I'm trying to figure out if it's worthwhile to turn off mobile data when the screen is off, and turn data back on when the screen is turned on. It would also be necessary for me to occasionally switch mobile data on even when the screen is off in order to check email. (I'm thinking something like 15 minutes off, 3 minutes on)
Does anybody have any success stories or advice whether I am likely to see any noticeable battery savings by doing this?
I started doing this from when I first got my evo. Just turn off mobile data, you can still get texts and make calls, and then turn it on when you need it. Also turning off background data in settings also adds additional battery, but just enable it when you need the market. I went most of all day with about 80% of my battery still good between it just being off, using the mobile data here and there, and some texting.
Edit: I don't use a tasker, I just use the power widget in my notification, so I can turn on my mobile data on/off with just a tap. And if you're like me you don't know when you actually need it or for how long. So I find it easier and more effective to do it manually.

X2, i use switch pro to toggle mine. Battery drops about 2% per hr while data is of with screen off even when listening to music from my play lists.
I turn off the "always on " mobile data and noticed a big difference. The data turns on and off with the screen.

Over the months I have been an Evo user, I have collected some valuable information that all users should probably know in regards to maximizing battery life. Besides the stuff about 4G and a few specific options, these steps apply to pretty much any other android phone running 2.2, and a lot of them apply to versions below Froyo.
General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users:
1. Turn off all radios when not in use.
(gps, Bluetooth, wifi, data, 4g) Use a widget like the default HTC power widget or Switchpro from the market. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
**IMPORTANT DISCOVERY**When you turn on your 4G radio, then turn it off, it will keep scanning and turning off all by itself.
The problem is apparently exacerbated by a 4G toggle widget, which causes the phone to automatically turn on 4G at boot. This repeating of scanning and disconnecting severely drains battery life, and sadly, no matter what ROM or kernel you use, there is only one way to fix it:
-If you don’t use the toggle widget, then you have to reboot your phone after turning off 4G
-If you do use a toggle widget, then you have to remove the widget from your homescreens, then turn off 4G via settings, then reboot.
**To check to see if this is happening, download alogcat off of the market. Look for the lines saying: I/Wimax ( xxx): <DC> Try to establish a connection to DC server.
E/Wimax ( xxx): <DC CONNECT> IO error: msg=’/xxx.x.x.x:xxxx –
Connection refused’
Over and over again.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Go to menu<settings<wireless & networks<mobile networks<disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you
This will prevent your phone from staying on when you don’t manually turn off the screen. Also with this, manually turn off your screen when you’re done with your phone.
6. Everyone has that issue where the first ten percent go the fastest.
This is due to two things. One is that these types of batteries stop charging once they get to 100% to prevent damage, and begin charging again at 90%. This means that you could potentially unplug your seemingly fully charged phone at 90% actual charge. The second is number 7.5.
6.5. Use the trick described in this thread, it works.
My idea behind how often you should do it is once a month, if you flash a new ROM, or if you stop noticing the benefits.
This is the calibration technique recommended by HTC themselves. Check it out!
7. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
8. People posting screenshots of the Battery screen as proof of long lasting battery are giving statistically irrelevant information.
See HERE That screen shows time since last REBOOT, not last charge. This isn't always the case, but a lot of people will post a lot of things about battery life, but look for definitive screenshots and testing results before you break down and cry due to the poster's life and yours.
9. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to menu>settings>about phone>battery, you can compare the two numbers, "up time" vs. "awake time." Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
Usually, SystemPanel will show an app that has gone "rouge" and is keeping your phone awake.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
Tips for Rooted users:
1. Try out custom kernels.
By going to the EVO 4G Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.pokedev.com/setcpu/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 4 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 5-10 of screen on
* *Heavy usage – LOTS of video watching and games, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

I am the owner of SuttCo. We developed the Locale Mobile Data Plugin (which can be used by Tasker). It has a condition that can keep tabs on your data use and a setting which can be used to shut off mobile data.
I know Tasker and Locale have screen off/on conditions. I don't have time to run any tests for you (busy working on a new plugin), but if you're willing to do a semi-scientific study and report the findings here... I'll comp you a copy of the plugin. Shoot me a PM.
Good stuff

Not to say that turning off mobile data when you're not using it is a bad idea but I've found during my own personal experience with trying to improve my battery life for daily use that using titanium backup to freeze Google Backup Transport.apk is also a helpful solution. Other things that helped are going into Accounts & Sync and turning off background data because believe it or not, that stuff eats your battery up like a fat kid eating cake...hahahaha...Anyways, another tip would be to hit up Display and turn off Automatic Brightness and play around with the scroll until you come to a setting where you can see because I've found that the Automatic brightness eats up your battery too, not as fast but it does! Another thing that I've done is this and although there are task killers that would do this for you....I've decided to do this myself and after using an app such as Facebook or the brand new CNN app, I've gone into Applications and force close them out just to save battery and all of this nonsense I'm talking about has helped me out alot......NOT TO BRAG but using these little tips of mine, I've gone from 2 and a half hours and I was at 70 percent to 4 hours, 36 minutes and 48 seconds and I'm at 68 percent.....and that's with out turning my phone off, that's talking on the phone, texting, checking my facebook, downloading some apps here and there and just leaving it on in front of me at my desk.
Please don't start posting "Oh what, you want a FUC%ing cookie now" and all of this....all I intend to do is help someone by sharing my story....that is all! I got to get my butt to working again...hahahahaha

I have setup a few Tasker profiles to do this exactly. I did this instead of JD because the free JD doesn't do exactly what I want it to do, and I don't want to pay for JD when I can emulate it with Tasker.
The only thing I cannot do, that JD can, is keep data on while there is an active connection. With JD, if you turn off the screen while there is an active data transfer, it will wait until the transfer finishes to turn off data.
According to the Tasker website, there is plans to make a state/event "connection data rate" which would make it possible to do this. But that has been in their plans for quite some time. (I actually happened upon this post while searching for a way to check if there is an active data connection with Tasker.)
Also, with the way that Tasker views an "Open program", the program has to be open in the foreground in order to be considered open. This makes it tough to keep data on when a specific program is open, unless you're planning on keeping that program in the foreground all the time. To get around this, I created a profile that leaves data enabled while I have headphones plugged in, since I have headphones plugged in while using all the programs that I want to have constant data with.
EDIT: here are the profiles, and the tasks that go with them (I also included a profile that turns off the wifi antenna after disconnecting from a wifi access point.)

Battery Save Like RandomKing
I find myself regularly repeating many of these suggestions on many threads to many different people on how to extend your battery life. When not in use, my phone loses at most only 1-2% battery per hour! So I'm making one thread in the Epic forums dedicated to maximizing battery life while trying to explain why these steps will work. Some battery improvements come at the cost of performance or lack of certain services. This must be distinctly understood, or nothing wonderful can come of these steps.
Step 1: Brightness & Battery
Let's face it. Our Android phone screens are huge. This feature is the largest, and completely unavoidable battery-drain. The only way to limit it is to not use the screen... ergo... not use your phone. But that clearly makes no sense, so how to limit that drain? Well, a good step is to turn down your screen's brightness to the lowest you can read clearly, don't hurt your eyes! For night-time use, there's an app that can turn the brightness down even lower called Screen Filter(Thanks to iModMM for the find!). Also, choose a nice dark background, something in the black color range. For all phones, the darker the color, the less brightness used, less power consumed! But for our Epic's Super Amoled screen, specifically, a black pixel is technically an "off" pixel. That's right, every black pixel on your screen is a part of your screen not being powered, since the Super Amoled does not need backlighting. Blackle is also a good alternative to the standard Google site for a black themed search engine, though it doesn't seem to be mobile optimized. Also, lock your screen with that nice little button on the top right side of your phone. Don't wait for it to lock itself! As far as the battery itself goes, charging to 100% can be tricky. The moment that led turns blue, your phone has generally reached 100%, but it will generally trickle charge between 97 and 100 after that. A good way to charge to 100 percent is to use an external charger, which generally come with 1 or 2 spare batteries for about $20. This way, the moment your battery dies, shut down, and pop a fresh one in.
Step 2: Using a Custom Rom
At this point, there are many Epic 4G custom roms out, and if you're in this forum, you've likely rooted or are trying to root. Well I will not go into rooting directions here. Take a look at one and see how it fare's out-of-the-box for you. If you choose to use my customized rom, you will find a task manager with a preset ignore list, ready to use as a one-tap app-closing widget; as well as the service-freezing patch mentioned below in Step 8 ready for execution through a terminal, and my entire setup(among many other mods, apps, and tweaks tested for the greatest battery performance). These are just roms I've used myself to great results. Many others exist. Updated 7/6:
RandomKing's Customized Rom
2.2.1 EC05 v.1 Plus [Journaled w/Genocide 1.0] [Screenshots]
SyndicateFrozen Rom
2.2.1 EC05 v.1.2
Bonsai Rom
2.2.1 EC05 v.4.1.1 Not Supported on XDA. Sorry.
Midnight Rom
2.2.1 EC05 v.5.3
Step 3: Disable Unnecessary Services
First and foremost, disable all location services, wifi and gps based. This will affect certain apps like weather apps, you'll simply have to deal with static locations. Next, disable data sync. Contacts will not synchronize with Gmail while this is off. You will have to enable it sporadically. The Gmail app also will not function while this is off, I recommend using the email app and simply adjusting the refresh interval. You can always manually check your own email . Likewise, you may put your phone into airplane mode altogether if you don't plan to use it for an extended period of time, such as school, work, swim meet, movies, or on an airplane.
Step 4: Task Killers and JuiceDefender
First, let's get JuiceDefender out of the way. It's a neat app, and in certain ways, effective. However, it's own effectiveness comes with certain contradictions. It disables nearly all signals, which will include, for example, Google Voice. In my experience, this app hindered certain other services, and if anything may have drawn further on my battery. My recommendation is to stay away from it. Now onto Task Killers, they are good, and they are evil. Let me explain. Many of us may find issues closing all the apps we open, and sometimes forget we left something open. A task killer can easily ensure that you've closed all of your programs. Now onto the bad. Task killers can try to kill certain system services. This is generally BAD. Certain services shouldn't be killed, and others can't be killed, and the ongoing battle only further drains your battery while trying to kill services that AREN'T actually bad. So on that note, the worst part of task killers is AUTO-KILL. Disable it! Kill it! Kill it with FIRE! I use Advanced or Adao Task Killer, with no auto-kill. It is one of the only widgets I use, and I simply tap it before I lock my phone each time.
Step 5: Widgets
If you don't need them, don't use them. Almost all widgets make continuous unnecessary calls to the Android system, and this can be a huge battery draw. Even simple widgets. Through all my testing, there's only 2 widgets I have approved thus far: Advanced Task Killer, Power Control. Other disapproved widgets: Pandora, Winamp, Weather(ALL OF THEM), etc.
Step 6: SetCpu, Voltage Control, and Over/Underclocking
As with much of this thread, this is opinionated and empirical theories. Through my testing, Overclocking is unnecessary, and guaranteed to draw on the battery. Most of these roms come from fantastic devs and are, by default, blazingly fast. Overclocking is completely redundant in my opinion, and I'm generally all about speed. Underclocking/undervolting may preserve more battery, but my opinion on the matter is similar to my feeling on widgets. If you don't need it, don't do it. If you feel the need to use these apps, a generally accepted setting for battery preservation is to undervolt to 800 max. and 100 min. (if your phone can handle it, some may experience wake-locks, raise min. to 200) on conservative governor, adjusting your profiles for when the phone is locked, unlocked and etc.
Step 7: Unnecessary Apps
Free apps are great, aren't they? But how many have you gathered, just because they're free? Now how many of those don't you use, but regularly draw on your phone regardless. There's an easy way to roughly check. Open your settings. Now go to Applications. Manage Applications. Take a look at which are running that you have not opened. Using a task killer prior, and waiting a couple minutes to see what re-opens may be a good way to check which apps are continuously running in the background and evaluate if they can be removed.
Facebook --- Notorious for running in the background. Disabling notifications may help.
Latitude --- Largest offender of location service usage. Neat app. Huge battery hog.
QIK/Fring --- Any video chatter really. If you don't use them, remove or disable them.
Browser --- Large ram usage. Try Dolphin Mini or Miren.
Step 8: Freeze Services
Using Titanium Backup Pro, MyBackup Pro, or Bloat Freezer (yes, non-free apps) freeze any of the following services:
sns --- (Will disable sns)
snsaccount --- (Will disable Facebook contact integration)
drm --- (May affect media programs like mediahub)
drmcontent --- (May affect media programs like mediahub)
systemupdater --- (Best disabled if on custom rom)
Enter the following commands into the Android Terminal to manually freeze the above services:
Code:
su
pm disable com.sec.android.providers.drm
pm disable com.sec.android.app.sns
pm disable com.samsung
Simply enter the previous commands into the Android Terminal while substituting "enable" for "disable" to manually defrost these.
If you would like a shortcut for this method, check out the patch in This Thread Also Included In RandomKing's Rom..
Step 9: Journaling
Journaling... some love it, some hate it. The fact remains, journaling enables extra write cycles. While this will prevent data loss, it also means more cpu usage. It follows that battery should last longer with journaling disabled. You can use chris41g's mod HERE to turn Journaling on/off at will.
Step 10: Turn it Off and Spend Time With Loved Ones
That's right. You're obsessing with your phone. Leave it be. Do something meaningful and memorable. Have fun with life! This is just a phone.
More coming as it comes to me! Including mods, apps, etc. aimed at improving battery life. Feel free to leave your own suggestions or questions! If this guide and it's features have helped you in anyway, leave THANKS so I know whether or not to keep up on it!
Y is this in q&a?

has anyone noticed an effect on the phone's ability to sleep when you manually reorder the apps alphabetically in the app drawer? I kept having problems and factory reset 2x. Now I did find 3 troublesome apps that although not apparently running in the background, kept my phone from sleeping simply by being installed. I also stopped ordering my apps, deleted the troublesome apps and now it seems my phone is working correctly. I wonder if that (editing the default order) could also prevent the phone from sleeping? Any thoughts?

I'm non rooted stock EC05. I used to use EDIT in the app drawer to rearrange my apps in alphabetical order (they don't arrange themselves automatically this way after rebooting). I had noticed in spare parts that my phone was never sleeping and killing my battery. I did a factory reset and it worked as advertised. I slowly added apps back until I found two that seem to prevent my phone from sleeping so I uninstalled them. Phone worked fine for a while but then started acting up again. I repeated the procedure, leaving only the apps my wife's phone had (hers always sleeps like a baby), but then my phone started up again. Tried another reset but this time decided to leave the apps in the order they put themselves and so far so good...wondering if that was doing something or if it is an app update that goes bonkers?

Hmm. If you can't narrow it down to a certain app, I'm not totally sure what it could be. Have you tried clearing the data/cache of Twlauncher? You could try a launcher like LauncherPro, you don't have to be rooted to use a different one.
No but if the problem comes back up I will try some of those...these are the 3 apps that when loaded caused problems: NIV Bible, Document Scanner, [I now have relacement apps for each of these now] and most recently Espn Score Center, but my wife had all of thse but the doc scanner and had no problems
i would check in spare parts to see which apps may be holding a partial wake lock. for me the facebook app was not letting my phone sleep until i disable all of its notifications.

Likewise. This is why I removed facebook altogether. The new mobile site has proven to be pretty useful now.

Yeah I found the same thing...but I would log out of Facebook too. Also the problem reappeared after a factory reset and I had not gone into Facebook. Are you saying that even if you don't log in, it can stop your phone from sleeping? My phone started doing it again a few days ago for no apparent reason, and I was able to stop that behavior by: finding and moving 2 apps from the phone to SD card (I thought I had gotten all of them), clearing any cache from different apps, and rebooting.

That wouldn't tell me anything when I had the problem. The only thing was Android System....and....the phone wouldn't sleep even if in airplane mode! Which meant it had to be a process or app doing it all the time. I had never thought to clear cache, but I wonder why doing that works? Also there's a menu option in Spare Parts about Button Behavior which leads you to believe you can make the phone sleep but the menu says "only available in Ver 1.5". I've checked the market and can't find a ver 1.5 Spare Parts...

I believe it means android 1.5, because that says "End Button Behavior", and no new phones have Call and End buttons on them. Because the "Fancy Screen Rotation" says 1.5 only also.

Step 6: Unnecessary Apps[/CENTER]
Free apps are great, aren't they? But how many have you gathered, just because they're free? Now how many of those don't you use, but regularly draw on your phone regardless. There's an easy way to roughly check. Open your settings. Now go to Applications. Manage Applications. Take a look at which are running that you have not opened. Using a task killer prior, and waiting a couple minutes to see what re-opens may be a good way to check which apps are continuously running in the background and evaluate if they can be removed.

I think you mean "Now go to Applications. Running Services." Going to Manage Applications will show all non-system applications and not tell you what is currently running, AFAICT.
Or am I mistaken?
Thanks for this thread.

No, there is a "Running" tab inside Manage Applications. An app doesn't have to have a service to be running.

That wouldn't tell me anything when I had the problem. The only thing was Android System....and....the phone wouldn't sleep even if in airplane mode! Which meant it had to be a process or app doing it all the time. I had never thought to clear cache, but I wonder why doing that works? Also there's a menu option in Spare Parts about Button Behavior which leads you to believe you can make the phone sleep but the menu says "only available in Ver 1.5". I've checked the market and can't find a ver 1.5 Spare Parts...

Sounds to me like a system process may be the cause rather than any particular application. For me also I had issues early on with the SNS service forcing itself to restart continually and being a battery drain. It usually takes a force stop on that service followed by clearing data in the sns app and rebooting to fix. Don't know if that will work for you, but hope it helps.

My tips you can add:
1. I always, no matter what, always have brightness on lowest setting! If you have a hard time seeing in sun, than do auto, but turn off when don't need to, I have on low 24/7. Then at night, I have this app called screen filter which lets you lower brightness then default setting(good on eyes).
2. I always have auto-sync off. If you want emails etc. configure with ur preferences. And most of the time background data. But with background data off, you don't have access to market and have to enable for use. Don't get notifications. Lately, haven't been getting WhatsApp messages. This is optional.
3. In wifi settings, network notification turned off. Haptic feedback and all vibration disabled. Sounds on key clicks or anything disabled. Auto rotate screen off. No window animations. Screen timeout, 15 seconds. Keyboard timeout, 3 seconds. In location, use wireless networks and gps satellites unchecked.
4. No live wallpaper! No bright colors! I use a black background for wallpaper!! Try to go a little dark, not bright, stay away from white! Id recommened, the full black wallpaper. Also on ur homescreen, avoid widgets! Especially ones that use live web feed like, facebook, scorecenter. These are battery suckers!
5. I delete all apps I do not use! Stock and user. Download titanium backup to fix this issue. I freeze, system updates, swype, drm content, drm content launcher, sns, snsaccount. I uninstall the stock browser, use dolphin!! I also uninstall, all sprint bloatware, my files, gmail, email, talk, news and weather. Uninstall all stock and user apps you don't use! Check spare parts to see what runs in the background that you don't use. Another thing to add, I uninstall swype and android keyboard and use better keyboard gingebread edition 8.
6. Disable refresh interval in facebook, do it manually when you are going to use it!
7. Use setcpu. Undervolt to 800max and 100min on conservative governor. Set profiles, when phone is locked and etc.
8. Now lets talk about juicedefender and task killers. Juice defender will work and is a good app! BUT: if ur a person like me, I text a lot in whatsapp and when u lock screen it disables data, so u wont get texts. Download it, take a look at it, try it out. I recommend using agressive mode. Now lets talk about task killers. Personally, I think they dont work at all, and actually waste battery then save it. I just would say don't use one, and use samsungs stock task killer(actually works!)
9. Use a custom rom and kernel. Always be up to date on updates. I usually use, SRF and midNight. All about preference.
10. Extended battery FTW!!! Buy a seidio extened battery! May cost some money, but will greatly increase battery!!! Or get a cheap asian knockoff on ebay.
11. Disable data and put phone into airplane mode when it wont be in use for a period of time. Like at school or work. I usually keep data off during school. You will see a difference with data on and off.
12. Always keep wifi, bluetooth, gps, 4g off when not in use. They will drain battery crazy!!! Wifi will search for networks constantly, same basic thing with gps and bluetooth.
13. Also do full charges!! At night shut off phone and let it charge for a good 8 hours. Then in morning, turn on still plugged in. The charging indicator will be red, leave it alone till its blue. Go get dressed and eat some breakfast lol. Then when you come back it should be blue. And when on boot, let it finish media scanning, don't interrupt it!!
I can guarentee if you follow my tips, you will see a significant increase in battery life!
These are my tips!! I will add more if I can remember some more!
Typed this all on my Epic!!
I'm currently on the CM7 ROM, I have juice defender and done all the minor tweaks as far as disabling wireless network location, turn off the wifi and GPS, and an app killer. I still only manage at max 9 hours before my phone tells me to recharge.
If your getting great battery life, help me and others by sharing your tips here.

Yeah, I need some help too. I get about a day and a half with no use at all, and about 10 hours with minimal use. 4 hours with real world usage... I can't deal with this. Could it be the battery? It performs like a 1 year old, used, refurb battery came with a stock phone!

Have you configured the battery since flashing the rom?
I get decent enough battery life, with light usage I can go about 36 hours w/o a charge but on my heavy usage days I usually have to use the car charger a few times a day.

all of these... biggest one is to turn off data when the phone is in your pocket. use wifi when u can, avoid using 4g unless plugged in, configure the battery in recovery (i've actually notice that this helps less than anything else for me), and finally: get an extended battery. it's worth the extra hours u can squeeze out of it. don't expect more than 4-5 hours screen on time with any rom/kernel/modem combo with a stock battery.

Yeah I also did that wipe battery stats at recovery.
I just thought maybe my expectations were too high, although it seems as if my battery drains drop pretty fast.
I would say about -10% battery drop every hour, just checking the time and send/receive text messages. Occasionally I surf the Web on the phone when on break at work. Other than that the phone is in my pocket, and after my 9 hour workday my phone demands the charger.
This is with the stock battery, so I guess this is normal unless I'm using the extended battery?

u could also run a kernel that allows for over (under) clocking/undervolting. that helps some, too
get the duricell portable battery extender, add milliamps to your arsinal in one way or another with extended batterys or whatever, if you call sprint and complain loudly and dickly they will rebate you the cost that u spend on a new battery or batt extender whatever... that being said all the above options work great, u can also use night mode on chainfire 3d to save battery, or perhaps half your pixel rate, or perhapes turn off some colors (havent seen an app to do this yet) and reset your battery memory in cwm, kill ur batt, charg while off, then cycle again like that. (theres an app for that) if your not rooted, root your phone. if you dont want to root your phone, cycle ur battery the old fasion way or pop it into a rooted phone and do it.
I used to get really poor battery life (due to my phone not sleeping as evidenced by Spare Parts app). I rooted, used Titanium Backup to freeze various apps, and got an Zboost antenna booster for the office and called Sprint who sent me an Airave for the house. I wiped battery stats and cleared my Dalvic cache and the thing the finally got me right was finding out the Amazon MP3 app was still logged in though not running. Once I made sure I was logged out of that and Lattitude (Google Map feature) and Facebook, I haven't had any problem with a sleeping phone. Stock Froyo, standard battery, but rooted. When they say a bad app keeps your phone from sleeping I think they mean an app that requires log in...although this does not seem to be a problem if you stay logged in from a browser, only from an app!

You may be shooting yourself in the foot with some of those things. App killers aren't that useful on Gingerbread since they keep killing apps that just reload on their own, and every time the reload it uses power. Just because an app is loaded doesn't mean it is running. Try letting the system take care of it. Juice Defender may help a little but it keeps shutting down data and starting it up, which means you don't get as much usefulness out of the phone and may waste power in some circumstances.
See what you have set to sync. Turn off any autosyncs you don't need, like weather screens, facebook, etc. If at all possible set them to only sync when you open the program.
I use the exchange option for gmail using the stock samsung app, which gives me push email but doesn't have to keep polling the server. I don't know if that makes a difference compared to imap, but it works well for me. don't think you have that option in CM7.
Wifi is a much more efficient way transfer data than 3G, use it whenever you can, and set it to never sleep. Otherwise the 3G radio keeps starting up again and wasting battery.
You can freeze the DRM stuff if you don't use it. I don't know if it really makes a difference but everyone thinks it does, so I do it.
Having a black wallpaper helps a little because on a AMOLED screen a black pixel uses no power.
The biggest battery killer is being in a bad signal area. If you always have 0 or 1 bars then your phone is going to always be draining the battery trying to find a good cell. In that case Roam Control may help you.
That's about all I do, and with the latest Stock gingerbread EH17 and EI22 I'm sitting with about 40 to 50% left after 12 hours, that's with light to moderate use.
I've been through the ringer with this. I'm pretty comfortable now, routinely managing to have 33% of battery left after 12hrs w/3g always on, sync always on, intermittent music listening, 2.5-3hrs of gaming and general "screen on" time (auto brightness), 1.1 GHz OC, no undervolting, and GPS always on. Here's what I'd suggest:
Flash a ROM w/ NO CIQ (thanks k0nane!) - In addition to being a leech on your privacy it's a leech on your battery. It's old news to long-time Epic owners at this point, but ditching CIQ improves battery life and overall responsiveness of the Epic. A popular stable Froyo ROM for this is SFR 1.2.
Minimize always-running services - Long press your homescreen, select "shortcuts," select "settings," and select "running services." Tap this to see what's running ongoing services (not apps) your phone is running. All of these are drawing current to stay in RAM. Things like Juice Defender, Tasker, and others show up here and draw power in doing so. JD and Tasker especially can drain a lot because they perform constant tasks as well. Uninstall them and let your phone manage itself.
The same goes for task managers and app-stoppers - Froyo and above does this fine on it's own
Freeze/Uninstall system services you don't use - This includes things like Sprint voicemail, the "Email" app, and the "SprintAndroidExtension.apk," and SNS services. You'll most likely find these on the "Running Services Page" as well. You can Titanium Backup to uninstall them, but I recommend the SDX Stock App Remover as that can restore them (TB can't reliably). TB can freeze these as well, which accomplishes basically the same thing. SNS is connected to Facebook, so if you use that a lot you might want to keep it. DRM services can also be removed, but may cause problems reading the SD card. I stay away from it.
Use Spare Parts to monitor wakelock and CPU usage - If you notice something giving you persistent trouble, shut it down. This is time-consuming, but you'll get a good feel for what apps are out there to accomplish similar tasks and which one best suits your needs.
Uninstall apps you don't use - Next time you wipe and flash a new ROM, reinstall or restore backed up apps as you need to use them and not all at once. You may find you don't need quite a few of them, allowing you to keep more space open on your phone and requiring less current to maintain them
Don't charge the battery overnight - most phones can reach capacity in 2-4 hours depending on charge level. Beyond that, holding at or around fully charged will degrade the battery by denying it the ability to release the stored energy. I charge mine in the evening a few hours before bed and top it off in the morning before leaving for work.
Get an 1800mAh battery sold for the Epic Touch - this is what moved me form "getting by" to "definitely comfortable." For around $25 (incl shipping) on ebay, I've gotten a new lease on my Epic's life. It may seem like cheating to bring in a new battery, but it makes a lot of difference WITHOUT adding more bulge to your phone (makes it a tad heavier though).
Hope this helps. Remember, of course, that what works for one phone won't necessarily work for another. Despite being the same model, minor imperfections in silicone can create individual temperaments for each phone.
I as always trying to make my battery last by stopping this and uninstalling that. Then I thought; why did I buy this phone with all of these capabilities to turn them all off
So, something like the "Hyperion Sprint Samsung Epic Touch 4G 2 x Battery + Charger" (too "young" to post a direct link)
Would fit in/work with the Epic 4G (without needing a new cover)? Even though its for the Touch?
Lol, I've been doing many of the suggestions across the board, and have gotten much better results. But I'm still not "comfortable" with my battery strength, especially when I'm unable to charge my phone all day...
Looking into your running services is a big one. week ago my battery life greatly decreased. I kept seeing market update pending and it wouldnt go away. Never update never go away. I manually updated the market and the battery is back to wonderful. It drops 2-3% at night off charger. Thats about 8 hours.
A sticky with all the main running services and which ones you can stop would be wonderful. I have sns services running. I think i can stop it but not positive. I also have sanservice running supposedly some type of samsung update. Its not doing anything but its been running for 2 days. No negative effect on battery(that i notice) but its running. Also make sure you turn location off. Ive also noticed that even when you back out of google maps its still in running services. A restart fixes that but thats annoying.

SNSservice is a Facebook and Feeds and Updates Widget service. ALWAYS stop it. It does not matter to Facebook, even if you use it, but if you remove the Feeds and Updates Widget on one of your screens, that service continues to search for it and will kill your battery in a matter of hours (it starts a "restarting" loop). Either leave the widget on or kill this service after every reboot or if you are rooted, freeze it along with DRM service.
My other battery tips are to log out or sign out of every app such as Lattitude, Facebook, Amazon MP3 (it's ok to use them, but don't just back/exit out, actually sign out of them so you have to log back in next time). Apparently, staying signed in causes your phone to not sleep and you can't find what is causing it (i.e. you can't see it "running" anywhere...people call it a misbehaving app, and you would have to delete apps one at a time to find it by trial and error).

General Lithium Ion Battery Information
^^This link includes stuff about charging, including trickle charging aka SBC (Why NOT to use it, or at your own peril)
My tips for good battery life:
Tips for Non-Rooted users
1. Turn off all radios when not in use.
(Bluetooth, wifi, data, 4G/Wimax/LTE, NFC, etc) Use a widget like the default power widgets, Switchpro, or a similar app from the market. Newer android versions generally allows users to access these radios and other settings from the notification pulldown menu, , under the "Quick Settings" tab or a row at the top of the pulldown. The radios of the phone draw power if on even if the user isn't actually utilizing the radio's functions. A radio searching for signal (if you are in a low-signal area) drains more than a radio with good signal, so again, turn 'em off when you aren't using 'em.
To manually turn off radios without a toggle, go to menu>settings>wireless & networks.
Wifi uses less battery than 3G, so use wifi when you can.
Unlike the others, GPS radios only draw power when you actually need them, so you can leave it on all the time.
2. Juice Defender is one of my favorite apps. Basically it controls your data for you to maximize life.
More explanations are on their page, search it on the market for free, or upgrade for more features.
Here are my settings for it: Click me
Note that for me at least, juice defender likes to deny apps data privileges whether you allow them or not, so screen on = data on works best for me.
3. I love live wallpapers, and I’ve always been a fan of pixel zombies, but they are really only good for showing off due to their battery drain.
4. Sadly, the "always on mobile data" setting is gone. This tip is invalid.
Go to menu>settings>wireless & networks>mobile networks>disable always on mobile data.
Product F(RED) said:
To clarify, "Always On Mobile Data", when turned off, lets the 3G modem go to sleep after the screen has been off for 5 minutes. It doesn't interfere with anything like email or any other application that requires an internet connection at that moment because it turns on on-demand rather than being on all the time and wasting battery.

5. Set your screen timeout to something that fits you.
The screen is the highest drain of battery power on any smartphone. BY setting the timeout, you can prevent your phone from staying on when you don’t manually turn off the screen. Also, manually turn off your screen when you’re done with your phone.
Menu>Settings>Display>Screen Timeout
I use 30 seconds.
6. Task killers used to be the shiz, but no longer.
Here is the ultimate, in depth, graphically assisted, explanation by the famous Fresh ROM's chef, Flipz. Shortly, in light of recent testing, really don’t do anything but force apps that the android OS needed to be open, and thus didn’t close, to re-open. So try not using them, unless for stuff like trying to figure out why your phone isn’t sleeping with system panel. You really won’t notice a performance difference, and the adverse effects you aren’t seeing will stop
+=+ A good alternative is the application SystemPanel Pro. It has a free version, but I highly reccomend purchasing the paid app. It basically monitors everything going on with your phone's usage both in real time an in terms of usage history. If your battery is draiging fast, it tells you what app was doing it, how much it was doing it, and allows you to stop it.
7. I'm sure you have all heard around that your phone isn't "sleeping".
This is referring to the phone's "awake" time, hence the name. When you go to Menu>Settings>About Phone>Battery>click on the small battery graphical, you can compare the two lines, time on and awake. Generally, up time refers to the amount of time since the last reboot. The "awake time" is how long the screen has been active. The problem is, a lot of the time, due to the endless possibilities of inconsistencies between apps/ROMs/kernels/phones, the phone will not go to "sleep", drawing power proportionate to the screen being in use when it reality the phone is sitting idle.
If you compare these numbers, and they are the same, or if you note the difference, turn off the screen for a minute, then re-check and they are the same, then your phone is not sleeping.
One solution is to reboot.
I recommend two apps to help monitor:System Panel and Better Battery Stats. These two apps (explained in their FAQ's and descriptions greatly aid in finding those rogues.
Usually, SystemPanel will show an app that has gone "rogue" and is keeping your phone awake.
-This is done by hitting menu>settings>monitoring enabled. Then after some time has passed, ht menu>monitoring>history>change tab to top apps, and see if anything is above, say, 2-4%.
Uninstall applications/reinstalling them slowly, checking after every install to see what is causing it is one tedious but surefire solution.
Lastly,
Follow these steps that I have discovered almost always work.
1. Reboot phone.
2. Instantly upon reboot, as soon as you gain control, open up some type of monitor/taskkiller
3. "kill all" tasks on startup; about 5 times in quick succession should do the trick.
4. Turn off the screen and leave it for about five minutes.
5. Check the up time v. awake time and see if they are the same.
6. If they are, repeat steps 1-5. If they are different, you are good.
8. Apps and Combinations to watch out for!
-Facebook- Tries to sync live feed all the time, HIGHLY recommend unchecking this box, as it creates a massive draw on data
-Skype- This app reportedly (I've seen it myself) likes to sync random data and open up the network for fun. Sign out of app when not in use to fix
A rogue process called "gsiff_daemon", associated with the gyroscope. Changing its name seems to be the only semi-permanent solution. It's located in system/bin.
Lightflow is a pretty damn cool notification/led manager, but it eats up ridiculous system resources using its alarm wakeups. Use at your own risk.
9. Manage your syncing.
This is a big one, and it differs from person to person. Go to Menu>Settings>Accounts and Sync, and take a look at what's going on there. The green or checked or activated box to the right of the option means that there is an account syncing data. I for example have four email addresses, facebook, dropbox, box, weather, etc. That is bad. You should go through and turn off syncing for nasty apps you didn't even know where accessing the internet, or limit the access of apps and services that you do want to allow.
The problem lies in the way this syncing is handled. Each app/service runs on its own schedule, making it particularly likely that your phone could almost always be establishing a data connection and trying to download data for your various apps. See step 2 regarding the app Juice Defender to handle this problem.
10. Vibrate Settings
Vibration and haptic feedback eat up a surprising amount of battery. If you have the haptic feedback enabled, then every time you press anything your phone puts out some juice to make itself dance.
At least on the GSIII, the settings are in menu>settings>sound
Some apps have their own haptic feedback settings, and notifications are their own set entirely.
Root Tips LIVE
Tips for Rooted users:
1. Try out custom kernels.
By going to the Galaxy S III Android Development section of the forums, you can see all of the different kernels being developed. These allow for all kinds of modifications like underclocking the CPU and undervolting, both of which save battery. To see how to use them, read the FAQ's in each thread's OPs.
Here is a great guide to custom kernel's by mroneeyedboh.
2. Use SetCPU in compliance with whatever your custom kernel allows.
This site will explain the basics of SetCPU: http://www.setcpu.com/
-Profiles from SetCPU should usually involve these for battery life optimization:
-Screen off at the minimum clock speed for both, with the max raised on level if sluggishness is apparent
-A temperature greater than “X”
-General power related profiles that lower cpu speed at lower battery levels
-Here are my SetCPU profiles: 1 , 2 , 3
-My profiles change a lot as time goes by, because different kernel creators recommend different settings. I suggest reading up on whatever kernel you are using to gather settings.
------------------------------------------------------------------------------------------------------
NOTES:
*Some apps or processes begin to run at startup and keep the phone awake. These apps are not detected by things like spare parts or system panel, unless sometimes represented in the "system" process, in which case its usage will be unusually high.
This shouldn't take more than three repeats, and if it does, you need to factory reset, and slowly add apps back to see what's causing the problem.
___--- When it comes to actually "calibrating" one's battery, there are a couple of methods floating around. The method I first learned is to charge the phone all the way, boot into recovery immediately, and "wipe battery stats". Then reboot quickly, and run your phone all the way to death without charging it, then charge it all the way without interrupting it, and you should be good to go. Do this when changing ROMs/kernels for best results.
----When it comes to people claiming 20 plus hours of moderate/heavy use out of their current setup or other ridiculous absurdities, consider my position: No matter what you do, the Evo battery is the Evo battery. You can tweak it and customize it with kernels, ROMs, and settings, but none of that will turn it into a car battery. The main problem (besides a false sense of pride) that leads to these reports is the misunderstanding of what the usage levels are, so here’s my best summary:
* *Light usage – Phone screen actually on for maybe 0-2 hours. Things like a few texts, some emails, 20 minutes web browsing, etc.
* *Moderate usage – You watched a few youtube videos or similar apps, sustained web browsing, hundreds of texts, some games. Hours range from about 2-5 of screen on
* *Heavy usage – LOTS of video watching and games, 3D pics or video, or some high def gaming/movie watching for at least an hour to an hour and a half in total, with lots of emails and texts, browsing, and other app shenanigans. 5+ hours
*I’m sure everyone doesn’t agree with all these numbers, but this is most likely a good average of what powerusers think. All specific hourage may vary due to differences in phones, batteries, ROMs, and kernels… Which also means that most battery comparisons are pointless; it’s only what you can improve on that counts!
I’ll update this whenever I see good stuff, people remind me, or I remember/come across things I do.
Hope it helps everybody!

Nice tips
I'm not quite sure if leaving the GPS on actually eats up battery now. I've seen articles now that state that GPS is only used if a program needs it. When I go into battery and usage, GPS will only show it has been used only a couple times with the apps that I opened such as Facebook, Speed Test or Gas Buddy. I think with ICS, it has changed in the way that GPS actually works and it is not actually constantly using battery.

This is correct and I have confirmed it. Just haven't updated the op.
Thanks for calling that to my attention.
The one about turning radios off is one that makes all the sense in the world, but I'm not sure in practice if it makes a significant enough difference to override the inconvenience of having to flip things on and off as needed.
I can only speak from personal experience but for about two weeks my wife and I, both with S3's, were shutting radios off when not needed out of habit from our Epic days.

My own take on that rule is to leave everything on and see what you see... it's always easy enough to turn things off if you find your battery life not living up to expectations and if it winds up being a trend, so be it, leave things off as suggested in the OP. For my wife and I at least we can get through an average day and finish up before going to bed around 30%-40% battery most days. To me, even if I could get that to 40%-50% left, that 10% difference I can accept for never having to worry about what's on or off.
Laziness has a price, and it's around 10% of my battery life apparently
great tips!!!! definitely improved my battery with these!
The radios are extremely dependent upon your area, signal strength, the walls of your house, the apps you have installed that actually call upon the data... So ideally, if your area has amazing signal, your walls are hyper radio permeable, and you don't have many data intensive apps, then you can probably get by with minimal loss. People who are feeling the itch to test should certainly go ahead and try, but the same could be said with most of these tips. This is simply a guide of suggestions. YMMV

The one about turning radios off is one that makes all the sense in the world, but I'm not sure in practice if it makes a significant enough difference to override the inconvenience of having to flip things on and off as needed.
I can only speak from personal experience but for about two weeks my wife and I, both with S3's, were shutting radios off when not needed out of habit from our Epic days. However, since then (well over a month now) we just leave everything on all the time... and I do mean *everything*: GPS, Wi-Fi, NFC, cell radio, BT... and the difference has been... wait for it... so little it's actually been hard to quantify!

Gps Radio?
Really? The radio, even if left on, uses power only when an app needs the position. I am kinda boggled by this? Wouldn't it take longer to aquire the location from the 3-7 sateilites upon the request and then shut back down. What would be the diference? This can't be true about the GPS not sucking any power in ICS when idle.

Try leaving it on for the day and go into battery and click on the graph. You will see that it should be black across the board for GPS if the signal was not used. Only time it would be green is when a program utilized it.
ICS changed the Battery Stats. It doesn't display that information in About Device. Uptime is there but awake time isn't.

Actually, that's incorrect. Menu>Settings>Battery>click on the small graph picture. It gives you many things, including time on battery, Awake time, Screen on time, and charging time. It's just graphically represented.
How do you accomplish #4?
Go to menu>settings>wireless & networks>mobile networks>disable always on mobile data.

I disable everything when I go to sleep at night, or when I am putting my phone on charge in middle of the day to maybe help it gain battery while not draining it, sort of like a power charge I like to think. It's so easy to do, just slide down status bar, uncheck everything (WiFi, Mobile Data, Sync, dim screen all the way) and that's it. I had 22h1m running since last charge today when I was at 4%.

It helps to use the right ROM and know how to work your phone:
:good:
Also, apparently Google apps backup is broken for some users. I had a problem with the phone not sleeping and traced it to google backup, apparently it's a common problem with ICS. This is unrelated to contacts/calendar sync. If you have the phone device rooted and use titanium you can leave this off, and as long as you don't lose your phone it's no big deal. Setting is under system settings -> backup and reset.
Figure I would show this off here, had the flu last week and was basically comatose for 30 hours. Only about 2 hrs screen on time, but all radios on and even passed out with navigation on after checking traffic at one point. 51 hours
Sent from my SPH-L710 using xda premium
I would try disabling Google backup so it no longer updated/synced my info to the web until I next turned it on, but the option says it deletes all the info already stored on the web. I suppose this is good if someone wanted to delete this info for privacy concerns, but there should be an option to just turn the syncing off, or to schedule it for once a day or something.
I have not tried disabling it as I do not want to wipe my info.
Better Battery Life Tips
I've been using (and tweaking) Android devices since the original HTC Dream (aka G1, Android Dev Phone) was released, and I've had devices that are both good and bad at power consumption. In this thread I will share what I have learned and invite you to share what you have learned as well so that we can all get the most out of our devices.
Please note that I like to keep my smartphones "smart" and don't like to be manually toggling things on and off throughout the day. If you like to geek out 24x7 you can manually turn on/off every feature of your phone every time you use it to conserve juice... that's not me though!
Here we go...
-Consider a Different Browser
It seems like Opera Mobile and Mini are the kings of battery conservation. I tried Dolphin, Boat, Firefox, Chrome, the stock browser, and about 10 others... I didn't see significant differences in battery with any of them, but with Opera I noticed the difference. It makes sense since Opera renders the pages and optimizes the images remotely and then sends the bare minimum amount of data to your device to display the page.
-Location, Location, Location
Android's location related services can be a big drain. There are 3 different location settings you need to know about.
1) Location Access (Settings -> Location access): For maximum savings, you can turn off "Access to my location". However, there are many apps that make good use of your location. If you don't want to cripple them, leave this option turned on but at the very least uncheck "GPS Satellites" to save some juice.
2) Google Apps Location Settings (Settings -> Accounts:Google -> Location settings): Allows Google apps, such as Google Maps, to access your location. Why this needs to be separate from #1 above is beyond me, but turning it on requires the above setting to be on as well. If you don't use Google Maps, Now, Plus, or any other Google services that use your location you can turn this off.
3) Location Reporting aka Latitude (Settings -> Accounts:Google -> Maps & Latitude -> Location Reporting): This is the bad one. Really bad. Wakelock and battery drain city. I don't even know why anybody would want this. Kill it with fire. Set it so that it does not update or report your location.
-Turn off stuff you don't use
This should be common knowledge by now... if you aren't using GPS, Bluetooth, or even 4G... turn them off. If you don't need instant notifications and app updates you can even turn off Auto-Sync. If you decide to do that, I recommend the Synker widget from the Play Store. It is nice and configurable so that you can sync on demand with one touch.
-ROMs and Kernels
I'm not going to go into these too much here... there's a whole development section devoted to them with tons of info. Generally you get the best life from the stock based ROMs. Liquid Nitro and HO!NO!'s v20f (+Wind kernel) are quite good. Next best is probably HO!NO!'s CM9. The CM10.1 ROMS and kernels have a bit of catching up to do at battery consumption, but they keep getting better.
-Kill Google Talk!
If you don't use this program, disable it. It is always trying to do something on the network. Even if you turn off data and wifi you can still get NetworkConnectivity wakelocks from this app trying to do its business! Killing it is the first thing I do after flashing a ROM, especially CM10.1. From home hit: Menu -> Manage Apps -> All -> Talk -> Disable.
*Some report that disabling apps through the Android OS might not stick. If this is a concern for you, download NoBloat or Titanium Backup and freeze this app. Or if you're a nerd like me, use a root file explorer and move or rename the .apk file in /system/app
-Kill Google+ (Plus)
Just like the above, if you don't use it, deactivate it. It also uses data and location services pretty regularly. Disable it in the same way, or use NoBloat or Titanium.
-Kill Google Now
If you don't use it, deactivate it. It uses data and location services pretty regularly. I like its features and keep it enabled on my N7, but leave it off on my phone. To turn it off, go into the Google Search app (long-touch menu/search button), hit Menu -> Settings -> Google Now. You'll see the option to disable it.
-Data-Toggling Battery Saver Apps
These are pretty controversial, almost as much as app-killers were when they were very popular. In a nutshell they turn your data connections on or off based on whether your screen is on or off. They usually will check to see if you are downloading or streaming anything before they shut off the connection. Then, they periodically turn the connection on while the screen is off so that the device can perform a sync to get emails, etc.
Should you use one? If you are running CM10/10.1/AOKP4x then YES USE ONE!! EDIT: THE LATEST VERSIONS OF QUATTRIMUS AND WIND FOR CM10.1 HAVE RESOLVED THE BATTERY DRAIN ISSUE. Use of a battery saver is no longer essential. If you still want to use one, read on...
Whether or not you use a battery saver depends on how you use your phone, and if you are willing to accept the trade-offs. These apps get their savings from maximizing deep sleep time for extended periods with zero data concerns or interruptions. If your usage habits allow the app to do its job, use it. If not, don't use it.
[What follows here is some long drawn out jibber jabber about the pros/cons of these apps. Read it if you like]
Some people love these battery saver apps and swear by them; others hate them. The reason some like them is because they get a few more hours of battery life. The reason why some people hate them is because:
1) They wake the device periodically to do their job... which negates some of the power savings you get from having them. To some people these tiny wakelocks are the most horrible thing ever... even if their impact is quite small compared to the power being saved. These people are usually the ones who live and die by their BBS logs. I'll admit, I was one of those people
2) Syncs are delayed, so messages and notifications do not arrive instantly but when either of the following conditions are met-
a) The screen gets turned on (which triggers data on and autosync)
b) The program hits a scheduled time trigger (usually at user selectable intervals)
3) There's a small lag while data connects when the screen gets turned on. If the screen gets turned on very frequently the constant on/off/syncing can actually hurt the battery more than it helps.
But, if you are ok with the delayed syncs and you set up the sync intervals long enough apart you WILL see a gain in battery life. Your phone will sleep much more soundly as well. With one of these apps my Nitro HD on CM10.1 can sleep all night and will only lose maybe a percent or two.
*Note that these will NOT help you at all when the screen is on, which is a bummer because the Nitro screen sucks down a LOT of power. Also, your usage patterns may make them ineffective for you... in which case you are probably better off without them.
Personally I get about an hour or 2 of extra life if I use one, but it's a trade-off since I lose instant notifications and a there's a slight delay while it reconnects to the network when the screen gets turned on. And the more you turn your screen on/off, the more it disconnects/reconnects/syncs... meaning it is using a bit MORE power than usual for those seconds.
[/jibberjabber]
The following are my favorite data-toggling battery-saver apps. All of them have "free" versions and more advanced "pro/prime/advanced/whatever" paid-for versions. These are not the only ones out there; feel free to report back on ones you prefer. If you find one that you really like, I suggest buying the pro version not only for the additional customization they offer, but to support the devs for a job well done.
1) DS Battery Saver - Super easy to configure and since it kills background tasks before sleeping it puts your device into a nice deep sleep. Also combines the feature of CPU Sleeper if you are rooted... it'll shut off a CPU core when sleeping.
2) Green Power - Works really well. The interface is simple and well laid out. I used it for years before I discovered DSBS.
3) Juice Defender - Another decent app, similar to Green Power. I personally preferred the options and the interface of GP better, but you may not.
4) CleverConnectivity +++Battery - The interface is a bit weak, and I had problems with the full data on/off features working on my P930 w/CM10.1... BUT this program has one very cool feature- it has an option for dropping the connection speed down to 2G/EDGE when the screen is off instead of disabling it completely. This allows syncs to still occur while still saving some power in 2G. I've even streamed Pandora on 2G, so in theory you could do stuff like that too. This feature worked fine on my P930 dispite the normal data on/off failing intermittently. There is a moment of zero data while it toggles between 2G/3G. I think this app might be awesome when development advances some more.
-Underclocking (rooted users)
Capping your max CPU frequency at a lower limit can save power. Quite honestly, for 99% of my daily use I can't tell the difference between the CPU clocked at 1.2ghz and 1.8ghz except that at 1.8ghz my battery bar laughs at me and gives me a wedgie. On custom ROMs there is often a built-in method to set the CPU clock frequency (Settings -> Performance -> Processor). On stock-based ROMs you'll need a 3rd party app like Kernel Tuner, SetCPU, or any of the other 50 options in the Play Store. You can usually safely set your minimum frequency to 192mhz, but some phone/ROM/kernel/voltage combos will cause stability or lag issues with doing this. YMMV.
*If you are using a CPU controlling app like SetCPU that allows for profiles, you might be tempted to set the screen-off frequencies to the absolute lowest setting of 192/192... be careful! This setting could end up costing more power consumption because the CPU has to work for a much longer time to handle the tasks at hand at such a low clock speed. If it was allowed to ramp up a bit the task would be done more quickly and efficiently. Honestly I gave up on setting screen-off profiles. I just use governors based on smartass which have their own screen-off settings integrated. Less adjustments needed, similar results. This leads us to...
-Changing governors (rooted users with custom kernel)
There's about 50 different governors floating around out there. If you don't know what a governor is or what each one does, read this thread: http://forum.xda-developers.com/showthread.php?t=1736168
In short: Any governor that is based on smartass, ondemand or interactive is going to be pretty light on battery, and you may not be able to tell the difference between them in normal use. I like smartassv2 and badass, which are both based on smartass. Conservative may sound the most battery friendly, but usually ondemand does better and is less laggy.
Try some out. Have fun with it. Eventually you'll want to start tinkering with the I/O Scheduler... that's a topic for another thread. There's not much battery life to be gained there anyway.
-Undervolting (rooted users with custom kernel)
WARNING: This can cause instability if done improperly. MAKE A CWM BACKUP BEFORE TINKERING WITH UNDERVOLTING!!! I've never seen *drastic* gains on any device, but you do get a little bit more life, and every little bit helps, right?
So if you want to do it, read this: http://bigfatreality.blogspot.com/2012/03/guide-to-undervolt-android-safely.html and then proceed with caution.
Generally you can aggressively undervolt at lower frequencies, but be careful at higher frequencies because your device needs more power under load and will not like it if it can't get it. If you're a car guy this is like running too lean of a fuel mixture
Kernel Tuner and IncrediControl have nice GUIs for fiddling with voltages. Remember, adjust in tiny increments, followed by thorough testing! If you get a crash or reboot then you've gone too far. DO NOT ENABLE "SET ON BOOT" UNTIL YOU ARE SURE YOU'VE GOT STABLE VOLTAGES!!!
-Screen dimming
Screen backlights use lots of power. This ain't no AMOLED where you can save power by using dark backgrounds- LCDs light up the entire display regardless of what is on them.
I suggest turning off auto-adjust and set your brightness at a level that is just bright enough to be comfortable. I keep mind around 30-40%. Auto-adjust periodically polls the sensor to get light data, and uses a small bit of power to do it each time.
Turn on the 'Status Bar Brightness Control' if your ROM supports it so that you can easily swipe your finger along the top of the screen to brighten or dim the display on the fly. In CM9/10(.1) this option is under Menu -> Settings -> System -> Status Bar -> Brightness Control.
If you MUST use the auto-adjust, consider adjusting the levels that it uses. Make them as dim as is comfortable for you. For stock-based ROMs you'll need a third party app like this: https://play.google.com/store/apps/...wsMSwyLDEsImNvbS52aXRvY2Fzc2lzaS5sdXhsaXRlIl0.
For CM/AOKP based ROMs this can be done from the Display -> Brightness sub-menu of your device's settings area. CM10.1 has an excellent and simple adjustment interface.
-Build.prop Tweaks (rooted users)
You can add the tweaks below into your build.prop file that may or may not help with battery life. Download BuildProp Editor from the Play Store and add them. They seem to help a bit, but it could be placebo effect. They certainly don't hurt anything so give them a shot and report back what you get. These seem to work with ICS and JB:
ro.config.hw_fast_dormancy=1
ro.ril.fast.dormancy.rule=0
ro.ril.disable.power.collapse=1
pm.sleep_mode=1
wifi.supplicant_scan_interval=180
net.tcp.buffersize.default=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.wifi=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.umts=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.gprs=4096,87380,256960,4096,16384,256960
net.tcp.buffersize.edge=4096,87380,256960,4096,16384,256960
^ this forum keeps adding a space near the 16384... there shouldn't be any spaces. I think they get disregarded anyway if they are put in the file, so no biggy.
^some of these have presets in BuildProp Editor, some you have to enter yourself. I copy/paste them individually. Don't paste the "=" signs though. Everything before the "=" goes under "Property Name", everything after it goes under "Property Value". If you are experienced you can edit the build.prop file directly using a text editor. Just back it up first and don't screw with the permissions.
-Some other useful apps that help with battery life:
*CPU Sleeper (root users)- Shuts off all but one cpu core when the screen is off. This probably isn't required with a good kernel and governor setup (and a stable phone that sleeps well), and if you are running DS Battery Saver this feature is built-in to it. It uses barely any resources whatsoever, so give it a shot.
*Greenify (root users)- This essentially freezes selected apps when they are not in use. They cannot do background tasks or wake your phone when they are not active. When you attempt to open one of the apps it instantly thaws them for use. After you are done with them it freezes them back up. It is quite brilliant really! It eliminates a lot of wakelocks and battery drain from apps trying to update, gather location data, etc. Use with caution though- don't greenify apps that you actually need to have a data flow from or ones that you use widgets for.
*RootDim (root users) - You know how when you are using your phone in bed at night and the screen is just too bright, even on the dimmest setting? This app lets you go even dimmer. Less brightness means less power, so it will reduce battery usage in the process.
-Apps that help diagnose battery drains
*Better Battery Stats - Good for discovering the cause of battery-draining wakelocks. Just uninstall it when you're done using it to diagnose- otherwise it is constantly doing its thing which is not going to help battery life any!
*OS Monitor - See if your CPU is settling down like it should and see what is keeping it busy. It also has a ton of other advanced options and features.
...there's too many apps to list here! Share the ones you like I'll add more later.
-Adjust your advanced Wifi settings
Go to Settings -> Wifi, then hit Menu -> Advanced
Most people agree that Network Notification should be UNCHECKED, Keep WiFi during sleep should be 'Always', and 'Avoid poor connections' and 'WiFi optimization' should be CHECKED.
If you have a noisy wifi router (some Netgears are guilty) that keeps waking your device from sleep with wifi packets you may get better results if you change Wifi During Sleep to 'Never' or 'Only when plugged in'.
-Watch the reboots!
Every time your phone reboots, Android checks the SD card for errors and then runs the Media Scanner to take inventory of all media files. Both processes consume power, so try to limit unplugged reboots. The more files on your SD card, the longer Media Scanner has to work, so get rid of unnecessary files cluttering up your card. You may have some luck using .nomedia files to tag directories to be skipped during scanning. You can also use an app like this to disable the automatic Media Scanning Service. It also lets you scan on demand. Caution- If you don't ever do a scan, then new pictures won't appear in your gallery nor will new music appear in your player.
I'm sure I'll think of some things later that I have forgotten, and I'll discover new things... I'll update this when I do.
Please share your findings so that this can be the best battery saving thread... In the world.
Very interesting and helpful info.
Thank you very much !!! :good::good::good:
Couple things I'd add, especially if you're running a CM-based ROM
Get NoBloat and disable the following:
SuperUser - Get SuperSU instead, less battery drain.
CM Update Checker - Every time I use my phone to go online (I don't have data on 24/7) this thing pops up and wants to check for updates, but never properly gets flushed. Disabling this one app dropped my hourly drain by about 1.5% on CM10

Thanks for this- I just disabled CM Updater.
BTW with JB there's no need to download NoBloat- you can disable most apps (including this one) from the built-in App manager. Settings -> Apps -> All -> CM Updater -> Disable
Here's another trick for a specific type of battery drain: (you don't apply the fix in on your phone though)
Symptoms:
1) Your phone drains its battery while doing basically nothing while connected to your wifi router.
2) BBS shows massive amounts of wlan_rx_wake wakelocks
3) Android OS seems to be a high contributor to battery use
Fix #1: (Found HERE) "Change DTIM value in your router configuration from 1 (default) to 255. This value is usually in Advanced->Wireless tab on most routers."
^Seems to help a lot.
Fix #2: Set a static IP on your phone for your home network. The easiest way to do this is to find out what address range your router uses when it hands out IP address via DHCP, then hard-set an IP on your phone that is not in that range so that there won't be any conflicts with other devices that connect to your network. You'll need to consult your internets and googles to figure out how to get this information from your router, if you don't know how. Once you know a clear address you can use, go into your phones Wifi Settings, long-touch your network name, hit 'Modify', 'Advanced', punch in the static IP you wish to use. This might not be an option on corporate or shared housing wireless routers.
Fix #3: Check ALL computers on your network for the presence of the Dropbox software. Mac, Windows and Linux computers alike. If it is running in the system tray, click it, go into preferences, turn off 'LAN Sync'. This little booger wreaks havoc with wifi locks on some Android devices.

I've found that for whatever reason the built-in app disabler doesn't always work. I still like using NoBloat better.
Second to this, once you do disable a bunch of apps it's good to boot back in to recovery and wipe dalvik/fix permissions.

Oh then I'm tripping then haha, I have a question though. I tried installing Liquid Nitro and every time I tend to wipe data, wipe cache, wipe dalvik, and wipe system. It just hangs at the LG logo and I haven't had the ability to try out your v7 or for that matter any of the other previous Liquid Nitro. I'll send you a PM since I can't really post in the development section due to my lack of postage xD :cyclops:
On the CM 10.1M3 with wind kernel 1.8, after one day of normal use with WiFi off and Data Off and Location services off I got Google Maps being the worst offender battery wise, the weird part is that I didn't really used maps that day. So even with everything off some service is still eating bat in background.
