Batter drain after gps usage. - Touch Pro2, Tilt 2 Windows Mobile General

so i found something strange.
the phone will last 24 hrs and lose about 5-10% battery life with light usage.
if i use google maps or any other gps app, the battery after the app is exited / task list show no running tasks, the battery will drain in under 8 hrs. or faster.
my only guess is, tho the app is not running the gps chip is still tracking / fixing to location with nothing making the calls. sort of like a stale process that does not list.
any other fixes for this besides a reboot?

It probably doesn't release the gps resources since they are shared with the other apps that use the gps. I haven't really got the result you're getting, maybe others can confirm or provide solutions.

GPS Power Drain
Yes, I get this from time to time, as I did on all my previous HTC devices. Supposedly, if you exit the program properly (ie, X to close), the program releases the GPS use and power drain stops. Many times, this seems not to happen and power draw continues at a high rate. When this happens, a soft reset is all that seems to stop it.
I have searched this issue for several years and tried many different settings and apps to close/edit resources, but it still occurrs from time to time, with no real pattern.
Guess we have to live with it and do soft reset if power draw is too high after GPS use. I have just gotten in the habit after using TOMTOM for a trip to reset the phone, just to be sure it kills the GPS usage.

My Kaiser used to do this often, I'd have to soft reset to get the drain from the GPS to go away, but I have yet to see this happen on the Tilt 2 and I use the built-in GPS quite a lot actually... I use it for Waze, TomTom, iGO, GPSToday.. I even use it in GCzII for geocaching a bit although the built-in GPS still blows for accuracy.

How can I check what ate my battery in the past 3 hours?

My battery life has been great with the current set-up, but in the past 3 hours something screwy happened. I basically went to a function and I turned off BT, Wi-Fi, Mobile Data and GPS. Only thing on was the cellular network and I swear I didn't use it for more than 5 minutes. The battery was at 98% before leaving, now in those 3 hours it came down to 50%. What the crap? The only thing I did was to play Super KO Boxing 2 before leaving for about 5 minutes(It still shows its battery usage as 20% but no option to force close, so I am presuming it isn't running). I did open Maps and HTC Locations(Sense 2.0) for 2 minutes but I closed it because I didn't need it anymore, I also disabled GPS right after that. Now after all of this(game and gps stuff) I had 98% battery. Yet 48% of my battery went into thin air just like that, my battery use is Display: ~40%, SKOB : ~20%, Voice calls: ~15%(About 3 minutes), Cell standby ~2%, Wi-Fi ~4-5% or something like that. These are from memory since I turned it off and kept it for charging.
Any ideas what screwed things up?
Edit: Just noticed you are already familiar with the battery %age lcations.
From what you describe, it sounds as though there were some apps running in the background, slowly om nom nom'ing your battery. I daresay there are a few apps on the Android Market and elsewhere that can tell you what services are running at any given time, so you could get one of those.
If you're after ensuring maximum battery life, however, your best bet is to shut down the Desire, then fire it up again. That way, you can be sure there are no background services to drain charge. Couple that with lowering the screen brightness and display idle timeout (not to mention upgrading to Android 2.2), you should be able to go at least a couple of days on standby.
Sounds like one of your apps is keeping your device awake. I'd suggest getting app monitor like SystemPanel and run the monitoring for a few hours to see which app is consuming the battery.
And get WatchDog. It will notify you if there's any app that use the CPU more than 20%. You can set the percentage yourself btw.
All right, I'll be formatting the phone and flashing the RCMixHD v8 ROM(Was using v7) and then see what happens. i can bet my life that it was either HTC Locations or Google Maps screwing things up.

If you get great battery life, please share your tips here!

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.

Best tip is to stay on wifi as much as possible. I got 3 days on wifi and about 4 hours use.

I turn data off when im not using the internet and when I'm just listening to musc I just put my phone in airplane mode
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).

[Q] GPS and Battery Drain

I've spent much of the last year honing my DHD for battery life with custom ROM's and automation apps like the fantastically versatile app TASKER. With it, I can automate just about any task such as turning on a data connection for 3 minutes every 4 hours to sync all my bits and pieces.
I als use another app, Juice Plotter to record a historical graph of batter use over time. It also has a widget which shows me amount of charge left in hours.
I've been using Tasker to automatically turn my GPS on when I open an app which uses it like CoPilot, Maps, etc... I've always thought that this would save battery life but recently ran a test where it's been left on continuously and I haven't noticed any difference in power use. I wonder if it only really turns on when needed and the GPS on is more of a standby until used, when it's immediately available.
I use tracking software should my phone get lost so would like GPS on constantly, but thinks that Prey and Avast! can turn it on when required anyway. I just haven't tested them.
Any thoughts?

GPS is turned off until an application with permission to discover your fine location uses that permission. If you turned off GPS, it shouldn't turn on anyway, but if you turn it on that is when it will start searching.

[Q] Battery issue: sometimes it drains very quickly

Sometimes the battery works great, lasts a couple days. And sometimes, I get strange spikes where the battery drains extremely quickly (see attached images).
I have tried:
1. New device - I swapped my unit yesterday
2. Hard reset - restore all factory settings (and erase everything) off the phone
3. Battery cycle - i.e. let the battery run out entirely, recharge it from scratch
I have also tried diagnosing the issue via the stock battery app, GO Power Master, and BetterBatteryStats, but I don't see anything out of the ordinary when the battery usage spike occurs. Maybe there is some process running wild, but it doesn't seem to do anything...
Has anyone had similar issues? The only non-Google Play store app I have installed is Visual Voicemail - the apk I downloaded from this board.
You have tried everything I would normally suggest, but might have noticed something. Your sharp drop coincides with that red band on your signal bar. The red part signifying no cell tower signal. The sharp drop seems to start there. Is your phone stuck searching for cell towers when it has already re-established a signal? The earlier dip in the battery also has a red bar under it.
Also battery performance is not linear. If you are at 50% after 24 hours, you will not necessarily get another 24 hours. I am alwaysfinding myself at 50% after 18 hours and think, "Cool, I've found the right kernel" but sure enough I'm still plugging it into charge at 24 hours!
I know you say you normally get two days (which is very good) but this is all I can think of.
I use a powerful automation app called Tasker. With it you can set any phone setting to any phone condition. I've just checked, and it is possible to set a profile based on signal strength. With this you could specify a weak or no signal to do any manner of things, from play a notification sound, to turn off 3G and auto-sync. Set an exit task and it will also turn 3G and auto-sync back on when signal strength is healthy again. Might be worth a try.
Edit: If you have root access, Tasker supports the app 'Quick Boot Plus' as a plugin. With this you could set Tasker to reboot your phone if it is out of signal for more than 'x' seconds. I know it might not be very practical, but it would tell you if you we are looking at the real culprit.
Another edit: Scratch that. You could set Tasker thatif it sees no signal for 'x' seconds, turn on airplane mode, wait 'y' seconds, turn off airplane mode. No need to buy a plugin.
Thanks, wnp_79 - appreciate the thoughtful response!
Yes, that's a good point - there is a drop in battery starting with the red line for the signal. I take the subway to/from work in the morning and evening. But I don't see any problems connecting after I get outside (i.e. it doesn't seem to be searching for signal).
Perhaps next time I can try setting airplane mode on/off when I notice the battery draining quickly - and see if that helps the issue. If it does, clearly it's a signal issue.
I like the Tasker idea, I will give that a try! Thank you for the suggestion.
I wasn't by any means expecting another 24 hrs, but that drain of "50%" occured over a span of like 3 hours... with no screen usage (i.e. the phone was just sitting next to me at the desk, supposedly "idle").
Whatever you do, don't cycle your battery deeply unnecessarily.
Sent from my HTC One X using Tapatalk 2
Thanks tsleng, will keep that in mind.
I guess I am surprised other people haven't seen this issue. Maybe it's something specific to my software...
I've got this issue but it's down to my signal. At home it's fine and battery last's me well but as soon as I get to work my battery starts to dip due to Vodafone having poorer signal. Bad signal is killing my battery too bad we can't change radio's as of yet due to no S-OFF.
what happens when we can s-off? i mean what adv will we encounter regarding with the issues that we are having?

Well S-OFF, we can unlock bootloader without having to use HTCDev meaning we can revert back to stock easily and without it tampering the status. We can lock it back to it's original state.
We can flash kernels without having to use fastboot.
We can flash radios. By flashing other radios we can improve our signals if one radio is bad, an improved signal is friendlier on the battery.
I get a weird spike too but mine causes the phone to die. Also mine was done overnight when I was sleeping. (see attachment) I'm not really sure what I can do. I hope this was a one time problem...but i'm not so sure. I'm still under warnty and this is my second HOX

SGSIII / General Android Battery Tips (Can triple battery life!) | Updated 8/27/12

This thread that I've revamped from my Evo 4G/3D days, hoping to share some of the love with newer users. Over the time I've been on android, I've learned a few simple things that can greatly assist in the battery life of our wonderful smartphones.
If you get anything out of the thread, please don't hesitate to rate it and drop me a thanks!
If you read the thread and like the tips, have a new one to suggest, or have a revision, please post it.
On a similar note, moderators, thanks for the sticky!
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. 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!
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

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.
BUMP

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.

well, when I turned Mobile Data Off, didn't receive any data (emails, etc.) so I turned it back on
I'm curiouis about this 1 as well. How do we accomplish this as I don't see that option?
Remove that "wipe battery stats" from your tips. its a old myth that needs to die permanently.

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.
