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.

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?

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

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).
just got juice defender ultimate, as it seems to do a good job of making my battery last longer....but there are so many settings, i'm getting confused.
I basicaly just want the best settings that will disable all internet to save battery, except for once every hour when my i want the phone to run the "autosync" process to sync my facebook, twitter, emails etc. i alsao want it to obviously allow me to connect to the internet if i manually start an app which needs it (internet browser, facebook app, peep, etc).
at first, the app seemed to be doing this, but now i'm finding that although it's doing a great job of saving battery, it's not syncing, and my internet connection doesn't come on when i open an app. (or occasionally, it will come on, then not turn off again until i manually tell it to.....which defeats the whole point of having jhuice defender...i got it so that the phone would automate this process).
any help greatly appreciated...
totally given up on these battery saving apps now. they all seem to do the same thing...
they work exactly as they should for a couple of hours (i.e. they cut out internet except when syncing or when needed for an app etc)...then they suddenly jsut stop working, cause my internet connection to be lost completely, and i can't get it back until I reboot my phone (losing temp root i might add, so having to go through that whole process again too).
i think i'm going to just suck it up and charge the thing every day...i bought an "extended battery" which is supposedly 2430mah (around twice the stock battery), but it doesn't seem to give twice as much performance....it just seems to slow down the battery drain slightly for the first half of the cycle....
i.e. it lasts for around 2 hours without going below 90%, then within the next 2 hours it will drop to 70%, within the next 2 hours to 50%, the next to around 20%, then finally dying within the next 2.....
this is with syncing on, occcasional text or email checking etc.
so i'm getting around 10 hours use instead of around 7 or 8. it's better, but it's far from being twice the capacity.
but anyways, yeh, battery saving apps jsut seem to kill my internet requiring reboot, so i'm gonna just manually cut internet at various stages through the day from now on, and keep charging every night? sound like a plan?

ok, i'll give the free version a try...but i'm not holding out much hope, i've tried so many of these battery saver apps now, they al result in my internet connection being totally screwed up until i reboot the phone.
The default settings are pretty good. I don't think I changed much in the way of settings. Your phone will save a lot of power throughout the night with this.
thanks! finally, a battery saver that actually works!
been trialing this today and so far so good.
7 and a half hour shift at work today, it's been syncing every hour (which i know has been working, cos on my break i had tweets and emails waiting, and again when me shift ended)...sent a few texts in the morning, on lunch and after work too. so far it's down to around 83% battery....
The important thing is that it hasn't destroyed my internet connection (touch wood). It switches it off until i unlock the screen, except when it periodically turns on to allow the syncing. It also knows when I am at home and will use my wifi instead of mobile internet.
I'm going to keep trialing it for a few days to make sure it definately doesn't crash my internet after a while like the other programs seem to. So far so good though. If it keeps working, i'll buy premium for the night mode feature. Save even more battery that way.
thanks again, very happy
No problem. Glad it worked out for you.
Green Power is no longer working at night mode....switching WiFi and mobile networks works still, but it doesn't seem able to switch to airplane mode. This is only since I rooted, but I'm on stock Rom and this appears to be the only problem now.
::EDIT::
apparently, someone else on their forums have the same issue, and it's a known bug, something to do with green power being "paused" then "resumed". weird how it's never done it before though :s
have uninstalled it and reinstalled, so hopefully that will sort it out :S
::EDIT::
worked perfectly last night, so it must have been a one off glitch :s
I have found that my One X often kills apps I have running when I press the power button and put it away for more than a few minutes. I know Android will try to reclaim resources starting with background apps but this is killing the app I am currently looking at.
I have almost nothing else running and my system normally has 200-300 mb of available memory so it is a very unexpected behaviour. A typical example is I have something like firefox displaying a page. I read a bit then press off. I come back 10 minutes later and it needs to restart and reload the page. With previous phones the app would still be in the foreground the next time I turn it on and unless I navigate away it would stay that way.
I have a nexus s running ICS and that does not happen.
I have a desire running GB and is doesn't hapen.
I have a desire running Froyo and it does not happen.
Is there any way to force a less aggressive memory management on HOX?
There is an option for this, in settings > developer options, furthest down under apps section, first one; "Don't keep activities" check if it is enabled.
Sent from my HTC One X using xda premium
.. also beneath it, there is a restriction "Background process limit", it may also cause immediate kills if "no background process" is set
Sent from my HTC One X using xda premium
Thanks for the suggestions but those were set normally.
Tried using the built in browser instead of firefox and the problem was significantly reduced. It seems the system has a bias against non google apps. Even so - this HOX is behaving different in this respect to my other phones. It is my expectation as a user that if I am doing one thing, that thing should still be there the next time I look at my phone.
Something on the device may be leaking and the result is this need to stop stuff. My money is on sense ( mainly because of the observed ripple/flicker on the home screen ).
I've noticed same with my new one x it seems over eager killing all apps even sense launcher.
settings are correct but using chrome I don't dear open anything else for fear of it closing chrome and having to log back into everything, sometimes its as bad as just answering call or replying to a text message and its been killed
just as annoying it even kills launcher if I press home after using an app for more than a few minutes I get the please wait spinner while it has to load launcher
had ICS on desire HD and on zoom tab... this is not how it should work can't believe a phone with more memory and designed to run ICS is having to kill everything when DHD runs perfect
annoying little thing that is so far ruining what is otherwise an amazing phone
Seeing the same issue on my One S.
This happens with Dark Meadow. If the screen times out, or you hit the lock button, the game kind of "crashes". Not sure if this is the One X killing it or whether it's how the app is coded.
It's irritating anyway ><
Applications with a notification icon have not this behavior. Is there a possibility to set a higher priority to applications without root?
I'm having the same problem.
With cm9 @ Desire Z, I could, say, restore my 3000 sms within GoSMS (which takes a while) and meanwhile do whatever I wanted with the phone, eg. browsing, texting and so on.
With the H1X, after a certain time, the apps gets killed/suspended and therefore anything that happened within the app - which is pretty annoying. Any solution in sight?
H1X @ ARHD
I get this too. Annoying.

Sense launcher closing is not cos of the over-aggressive app killing. It's cos the system needs more RAM, so closes Sense since it's not directly in use right now. I do notice that some apps are getting closed after a period of inactivity, probably a default ICS setting that we can tweak when kernels and ROMs get more mature releases
I'm suffering from this defect as well. It's frankly astonishing that this phone behaves in this way. Really makes you wonder if anyone actually uses the phones before releasing such junk. What use is such fantastic hardware if it performs so badly in real use conditions. Every time I press home, loading. Try to run some javascript Web pages then go send a text, then back to browser and all tabs have to refresh. Mine is going back if it doesn't get fixed pretty quickly as it's practically unusable in this state. Battery is unsatisfactory as well. 2 hours on battery, screen on for an hour, 57% left?! What are they thinking seriously

If your battery is that bad you have a bad app running rampant or your battery is faulty.
For everyone else, even in settings if "Don't keep activities" is unchecked, try checking it and unchecking it. I read that sometimes it is still set to "Don't keep activities" even if it is unchecked and checking and unchecking it could solve the problem if this is the case. Doesn't hurt to try.
Hopefully one of the devs will make a Rom/kernel with better oom adjustments... I'm hoping.
the multitask implementation on this phone is terrible. I was using runkeeper, stopped to check something in my settings during the ride, phone closed the runkeeper application deleting my ride. It is getting annoying ...
Hey guys just wanted to take some time to make a post about some things that I am getting use to. I have been an apple product owner for the past 5 years and this is my first non iphone. So far I enjoy my phone but there are some small quirks that I am having issues with. I will list and detail these issues.
1. Haptic feedback always finds a way to disable itself. I always have to go back into the settings and re apply the haptic feedback.
2. The battery is god-awful. I'm not rooted or undervolted. Just stock at&t phone and I'm lucky to get 6 hours off the charger. As in my phone comes off the charger at 9am and by 3pm it is already dead. Is this typical? I read that the facebook app affects the battery life, so I removed it.
This is one of my biggest complaints. My iphone 4S easily went from 9am-7 or 8 in the evening.
3. My home button is not solid. When I push it the feedback is not consistent. Sometimes it makes a light click, other times it feels normal. I feel like maybe something has gotten into the surrounding area around the home button. I take care of all my electronics so I doubt this is the issue, but I didn't want to discount the idea.
4. I have downloaded an advanced task killer, but are there any other tricks or tips you guys could let me in on? Or any apps that would be recommended? I would appreciate the feedback!
5. When receiving photos from iphone owners my phone displays pics as a video file? How can I just get normal mms's from iphones?
OH YEA...when is the GS3 going to get jellybean? My at&t phone still has ICS, and I keep checking for software updates every 24 hours and as of this evening I have not found any updates to the new OS.
1. where are you enabling haptic feedback?
2. as always, battery life depends on usage. screen on time? do you have a lot of apps that could use data? do you have both wifi and data enabled when you're not around wifi? try disabling any stock apps you don't use.
3. i don't have anything to say about this. try comparing to other s3s if you can. then you can figure out if your phone is a problem or it's all of them. i personally don't care nor try to feel the difference if there is one. i tend to use back until i exit the app, not use the home button.
4. task killers are not beneficial to you at all. they actually tend to kill the battery faster. uninstall yours and see how your battery life fares.
5. no one knows when official jelly bean will come. if you root and install a custom recovery and start flashing roms you can try jelly bean right now. but it won't be with touchwiz nor will it have everything working as you would find it in your stock rom.

Thanks for the quick reply. My on screen time is typically in the lower 4 hour range, I would post a screenshot but I am unable to since I am a junior member. I will not disable data as that is completely unacceptable on a smart phone. I didn't realize but my friend deleted my task killer a couple days ago. Using his GS3 I can tell a noticeable difference in home buttons-I wonder if at&t will replace my phone (within 22 days)? I guess I'm waiting for JB just like everyone else.
I am enabling haptic feedback via settings>sound>haptic feedback btw.
I've had my GS3 for about 4 days now and my battery life is awesome. I can go from about 8:00am to around 11pm before the battery icon even turns red.
apparently there's a gsiff_daemon bug or cell standby bug? i haven't personally experienced those, so i couldn't tell you much about them. turning off data is only acceptable if you're trying to avoid an overage, so i get where you're coming from. if your task killer is gone and you're still getting horrible battery life, something else may be the culprit.
a few suggestions: disabling unused stock apps (flipboard, those att apps if you don't use them). i don't know what you need synced but if you don't need your calendar or browser synced you should turn off sync for that. do you use the power saving option? if you don't need much processing power i'd turn that on. auto brightness may help too.
about the home button, if it irritates you too much att will likely replace it. maybe the new unit will have better battery life?

I think the biggest thing that seems to help battery life is keeping the power saving mode turned on all the time. Seems to make a HUGE difference with battery life (especially on stock), but doesn't really seem to affect functionality.
Yea I removed all those crappy widgets.
My phone is always in power saver mode! I'm going to try to get a new unit tomorrow. How does this work? When i had my iPhone I just scheduled an appt at the apple store and they would always switch my phone out whenever I had issues under 1 year.

If you bought at a local store, you should be able to call them up and ask for a replacement for a defective device.
It shouldn't cost you anything as you are within their 30 day return window.
Oh... and as for official JellyBean.... isn't the rumor so far saying potentially late Q3/early Q4? Apparently the International version of the S3 with the quad-core processor is expected to get Jellybean shortly after the "Samsung Mobile Unpacked" event taking place in Germany tomorrow. Haven't really seen anything concrete about when our S3's will see an official release... but seeing as T-Mobile also just recently had an official build leak for the S3, i wouldn't be surprised if the late Q3/Early Q4 speculation could be correct.
Root, install custom rom, install Ktoonsez kernel... Battery life will easily double. If you really want to get the most out of your battery, consider AOKP or CM10... Jelly Bean based, with 0 bloat and almost none of the background process the stock TW rom runs in the background.

4 hours screen time is a lot... even on my iPhone 4 and priors (I had them all) with that much screen time I wouldn't get more than 7-8 hours. Keep in mind you are going from a 3.5 screen to a 4.8... this screen will eat up battery at a faster rate.
With an average of 2 hour screen time I usually get 15-20 hours out of a full charge pending usage. Nothing special, rooted running triune, stock cpu settings.

I think after a bit of tweaking you will see better battery life. I get much better battery life than my sister does on her 4S. Also, disabling data won't hurt anything if you are not using the phone. I. Don't charge my phone overnight anymore.... I disable data while I'm sleeping and charge in the am while I'm getting ready for my day. With a few tweaks you should be able to make it through a full day, even with 4 hours screen time. Take some of the suggestions others have mentioned here.

1. happens to me as well when i turn powersaver on and then off again. (powersave disables haptic feedback, but it doesn't turn on again sometimes when i turn powersave back off) probably will be fixed in next update.
2. don't have this issue at all. how is your screen on time and what do you do on your phone? (ie: any specific apps/games you use?)
3. my home button is definitely solid.
4. do NOT download advanced task killer. it is not needed as android will kill off apps when it needs to. there's also a built in task killer if you'd like. just long press home button and click task manager.
5. happens to me as well but when i save the photo it changes back to jpq file.
6. jellybean hasn't been released yet for s3
Root your phone, install CWM and ktoonsez's sammy kernal. Stock rom by default has the performance governor enabled, which I believe has the phone either running at the lowest clock or the highest clock with no real middle. Rooting your phone and installing a custom rom will allow you to have access to more governors that will treat your battery much nicer as well as his custom kernal has added features and just performs faster as well as has better battery life.
There are all kinds of tutorials on the site and I'm sure even some youtube videos on the process. The only other thing I'll add is to READ READ READ on how to do the process, READ READ READ the thread for possible issues and READ READ READ some more for fixes to any issues that may arise.
The great thing about android is the ability to change almost everything about how your phone acts and operates. Once you start you'll end up like me that whenever you get a new phone, you'll already have downloaded root/custom rom/custom kernal on your home computer so that you're ready to get off of stock within 30minutes of being home.

1. I've noticed that when I enable battery save mode, it turns off haptic feedback, so it might be that.
2. Like others said it depends on what you do with your phone, but on average, I usually get 15-20+ hours on a charge with at least 3 hours screen time.
4. I wouldn't use task killers. But it's smart to do a little management of tasks yourself. For example, when you want to exit an application, don't just hit the home button, hit the back button until the app exits. From my experience, depending on the app, this will actually exit the app and not just leave it running in the background. Also, every once in a while, I pull up the multitasking screen by long pressing the home button, and I hit the "remove all" button to close any applications that I don't need running in the background.
Also, you may want to try installing Juice Defender. What that app does is turn off the data connection when the phone is in idle, and it turns it back on every 15 or 30 minutes (configurable) to synch, check email, etc. The phone connection is always on. It's actually made a noticeable improvement to my battery life. But this also depends on if it's ok with you that you only synch every 15 minutes. For my girlfriend, she likes to get 10 minute warnings when ebay auctions end, and with this installed she's missed some auctions. So it doesn't work for her.
Imo, the single best way to save battery is to get an app to automate toggling data off when you lock your phone. I've been using a Tasker profile to turn my data off after the phone has been locked for 10 minutes, and turns it back on when my screen unlocks. With data off, my phone drains maybe ~1.5%/hr.
Whatever you do though, you likely won't get more than 3-4hrs of screen time, considering the phone is 720p and 4.8".

Just a departure from what I'm use to(my battery on my old 4S was substantially better)...if I didn't want my data on all the time I could have bought a dumb phone ya know? Anyways with data turned off battery drain was better ~5% hour.
