I had a Evo before and the Android System used maybe 15% of the battery (as seen in the battery stats section of the settings.) Now I have an Evo with far worse battery life, and it says that 55% of the juice is being used by Android System? Anyone know why, or how to fix it? These are essentially stock Evos, no rooting or such. Thanks.

Mine says 30% right now but that's with me playing on it for a while tonight. Try a battery pull, or reset it.

Click on it and see how many apps "android system" contains. Also if you havent made any phone calls or used 3rd party apps to much "android system" will occupy most of the battery.
Ok, did some research and found that people have been having issues with version 1 of the HTCfacebook app keeping the phone awake all the time and killing the battery. Seems.it.can not he deleted on non-rooted phones, but I did force close it and the drain on the battery seems to have slowed, and the system is down to 30% battery usage. now, does anyone know how I might delete this app without root? (this is the app which comes preinstalled and runs all the time in the background, not the one downloaded from the market.)

Did you make sure it's not set for auto sync using the HTCfacebook app?
You should be able to update it to the newer version that fixed that issue. No need to delete.
How does one update the preinstalled version? Thx.

I re-read one of your posts and noticed that its the htc facebook that's giving you the problem.
You should be able to download facebook for android (ver. 1.3.2 I believe) on the market and that should become your default facebook app and solve your issue.
Thanks lovethyEVO, I have done that but the default app keeps running in the background
Wonder if you went to settings, applications, and found the bad fb. App. Then hit clear defaults. Now set the upgraded version as default. Idk. It might work
Was going to suggest an autostarts type of app, since you can't uninstall it unless your rooted, but it looks like you have to be rooted on autostarts also. You can maybe try to find one that doesn't need root, or an autokill type of app. You can't uninstall it, but maybe you can keep it under control.

Thanks all. Well, I spent about 2 hours rooting from 2.2 today, and now I am running Fresh, which seems to have far superior battery life. Thanks for all of your ideas. (rooting the Hero was way, way easier)
i would like to know if this problem continue on jvp.
it will be much easier to see it in one post instead of following it on 3 different post.
No battery drain for me. I did 34 hours with one charge.

Definitely no battery drain here. Auto-rotation and GPS is ON all the time, played orientation-based and 3d-intensive games multiple times, used Google Maps (just had a nice tour today here in Japan )
By the way I haven't charged yet since I installed this rom 2 days ago.
samsung finally solved it or you did not have the problem before?
same for me right now i am at 1day and 8 hours with wifi on the whole time 3 hrs of calling and texting ,few games,radio etc i always have had the battery drain in the previous roms so this one is looking good
No drain here. With one charge phone now survives two days of intense use.

I surely had it before that is why I started this infamous thread: http://forum.xda-developers.com/showthread.php?t=1039696
No unusual drain here.
In fact this is the best battery efficiency out of any rom (except stock 2.1) I've used. Down to 64% after 24hrs with pretty low usage, which is subjective. To put it in perspective I rarely got past 24hours with typical usage on any 2.2 rom.

Well, it depends on personal preference , but for me bloatware is software that I will never use, or use someting else instead of the preinstalled one, for exaple : layer,mini diary, write and go, thinkfree office, stock audio player, swype, stock gallery app, samsung apps, touchwiz+widgets, live wallpapers,dual clock, etc.
Of course you need root, and titanium backup to remove, or you can delete the apk`s manually with root explorer, just don`t remove crucial stuff. You can search on google, or in the forums for a list of files,that can be safely removed.

For most it is amazing.
For me it has been so-so but I am letting it drain to calibrate now. Maybe it just looks like it's so-so.
persistence (with a modicum of technical ability).
Ever since I received my SGS 2 I've been plagued with "poor" battery performance - The stock ROM that came with it wouldn't stay charged longer than 12 hours when I was doing nothing with it and barely 6 hrs when I used it. I quickly discovered that Samsung had released a newer version via KIES, updated it and it improved it, not life changing but just enough to see me through the working day.
I was also disillusioned with the stock ROM that came with the phone - too much "bloatware" that I'd never use. Found this forum and started by rooting the phone, then using CWM and Titanium Backup to make full backups before moving on to loading custom roms. Tried the 3 that seemed most popular and stable - VillainROM, LightningROM and DarkyROM.
Much preferred Lightning ROM but after I'd installed it found that battery life was abysmal to the extent that I could have the phone plugged in and charging via USB and the battery would continue to go DOWN!
After restoring back to a CWM backup I did more research and found an app that would let me know what was killing the battery (see link at end). I re-installed the Lightning ROM and found that a security application called Privacy Guard (not LBE Privacy Guard) was chewing the battery up. This now made sense as this particular app had stopped working as it should after upgrading to Lightning ROM.
Un-installing this app made a massive difference to the battery life.
During this period I did have Juice Defender installed and since rooting the phone SetCPU. I had also encountered the "issue" with SetCPU appearing to cause reboots, closedowns and had turned off the functionality. But I was trying to use setCPU under the stock ROMS not a custom rom.
Since fixing the Privacy Guard issue and performing a clean install of Lightning ROM I now have a phone which lost only 3% battery last night (almost 8 1/2 hours).
I now have Juice Defender Ultimate, SetCPU configured to on-demand between 200Mhz and 1Ghz (I raise manually when I play games needing 1.4 or 1.6Ghz), Timeriffic to turn stuff off when I don't need it.
I have also put time into either removing or freezing (using TB) apps that I won't need.
Yes when I use the phone the battery goes down but it's a powerful phone and I treat it the same as a laptop running on batteries - The more I use it the less the battery lasts, get use to it people!

If you use it correctly and know what it is doing = yes.
A solid tip is to never ever ever ever ever ever ever use any of the bloatware provided by Samsung. Don't even start it once because some stay active even if you don't use them. They drain the life out your battery and there are enough good alternatives.

It's an old one and oft repeated, but for anyone fresh to the 4378 (and counting) battery life threads, get out of Google Latitude and stay out - kills the battery
I'm wondering if you use your phone frequently all day and JD constantly renegotiating connections is it better to not use it at all
Sent from my GT-I9100 using Tapatalk
If you are using yout phone really frequently (data) then JD is useless, but for me it really good.
I have bad signal at work, so I have JD set to sync every hour, preferred wifi and automatic night mode when i'm asleep.
Data on when screen on and everything is fine (for me).
Is there a safe way to delete bloatware apps? I mean what if I delete something that messes up the phone? Do I need to reinstall the Rom?

It works or not is a different matter, IMO it is not needed, nothing is needed actually. Just install JD and you will see it under Wakelocks in Better Battery Stats. So it drains more than saving it.

Thanks a lot!
For working and busy people, i think you guys can get better battery life than me. As a student in a holiday(nothing to do except playing ps3 and running errands), I most of the time will unlock the sgs2 whenever i glanced or watched it. moving the icons around, changing launchers, putting widgets, etc... i took so many times using sgs2 everyday and it can last about 6-7 hours with almost all the time screen on except when i sleep.
for me, 10 hours is already ok. get used to it guys. buy a spare battery, or an external charger. no need to worries at all. you dont want to be a freak for battery life. constantly checking the battery and whats draining them. its not cool~~ use it to the fullest! until the manufacturers make a phone with large battery capacity! i mean officially. those 3rd party large battery are just a show off. they drain as much as the stock ones.

Not sure - it may have dependencies with other more useful tools such as Maps. Just make sure you are logged out and keep clear of it - it's reasonably well behaved if left alone.
I have always used Stock not rooted yet and get around 13-19 hours, I don't use the samsung hubs, but have facebook, twitter, google + and three emails constantly running and use wifi browsing a lot
so am quiet happy as it is hence no need to root although I like flashing the new firmwares via ODIN
Just a brainwave??
With Titanium Backup you can freeze your unwanted apps. When the phone is working without problems you can safely remove the frozen apps (after making a backup of course)

36-38 Hours Battery Life!
I moved over from the HD2 a month ago. One of the things that astonishes me about the S2 is the battery life.
36-38 hours is the norm for me.
This is with:
- VillainRom
- Push Email (heavy use ~ 100 per day)
- No Lattitude
- No Wifi (HSDPA sufficient)
- No Bluetooth
I don't spend a lot of time making calls but being relatively new I am constantly fidgeting with it.
I am now on 25 hours without a charge and still have 65% battery left. Previously I couldn't make it through the day without hooking up the umbilical cord of life. I used to clear apps regularly with the stock task manager but would start out with 150MB free after boot and by the end of the day could not get better than 80MB free. Everyone was crying memory leaks. These are NOT memory leaks but errant programs that cache behind trhe scenes draining your battery and stealing resources. They are also immune to the stock task killer.
I found these bad bad apps by installing Memory Booster Lite from the market. After getting a 0 applications closed I went into the Task Killer in Memory Booster and found a bunch of apps loaded into memory still! Things like Google + hogging 28 MB of memory! There was Amazon Appstore, Maps, Facebook, Beatiful Widgets, Email, Telenav, Netflix, logsprovider....all immune to the stock task killer and slowly eating memory during the day as they load. I killed all the ones I recognized (no com.XXXX stuff) and then checked back in a few minutes to see what would reload. Google +, Beautiful Widgets, Facebook, Maps, and others would reload. Using the paid version of Titanium backup I froze apps like Google +, Maps, Netflix, and others that I don't use daily. You can use other apps for this like Autostarts. I deleted apps that are not worth my memory and battery power. I also set all syncs to manual and keep the display down as low as I need to. The results were tripling my battery life. I also stay on Wifi as much as possible and as soon as I get off XDA App, Tapatalk or any browser clear it with the stock task killer. I always have about 140 MB free now.
Your mileage may vary. The display is the biggest battery killer so if your a gamer, or spend hours reading, don't expect a lot of improvement from this but you will see some. I hope this helps battery life and memory leak myths for some of you.
The important thing in this forum is to have fun and help others.
I'm not trolling, and you do have great suggestions here. I just wish there were some easy way to get an entire day of full use without having to get an extended battery while using the epic to its full potential. I like autosync, adecently lit screen, and my range of Widgets which I use daily. Too bad I can't go more than 16 hours with everything on. I have tried at one point most of your suggestions, and it did greatly improve battery life. I suggest anyone at least give it a shot and then slowly turn back on the things they must have, like gmail sync or haptic feedback.

Blankrubber, this is a good place to add on to what I just found. The key is to see what else is running that is immune to the stock task killer. I never knew how much Google + and Maps were killing my battery. I got rid of my extended battery long ago but now I am sill amazed. 29 hours and 52% left. But the key when you say using it fully is limiting display time and intensity. No matter what that is the biggest drain so if you are glued to your phone for over 4 hours it will always be tough to make it last. Phones that used to be just phones could go days without charge. Now they are little computers. Think...laptops only go about 2 hours runtime without a charge and those batteries are a lot bigger.
I use Bloat Freezer myself. It shows whatever is running in the background highlighted in gray. Google+,Maps, the others Kenny mentioned are the usual suspects. Doing what Kenny said will help out for sure. Yes, its annoying we have to do this to extend battery life but some apps are always at work. Memory Booster is pretty good. Viper baked it in a ROM a while back. Its definately worth checking out

If something is just sitting in memory why would that have any effect on battery life? It should actually improve your battery life cuz then it just loads the app from memory and not a full re open of the app. Now if your saying that these questionable apps are just running processes then yes that would have an effect on battery as it is just sitting there doing something. But back to the memory side of this. Memory is used in all devices to take some of the load off the processor to make it load faster. It is there for a reason every device would not use memory if it was not efficient at loading apps and saving battery.
But if you only use the app once a week or so why waste those resources or the initial load time. If it sits in memory and another app needs that memory the processor uses more power and battery swapping apps in and out of memory needlessly. My phone is super fast and running 32 hours with 46% left. I can't put up a better argument than those results. Memory swapping is bad on battery it seems.

I've been around the Android platform for more than 3 years. I've pretty much read all google has shared with us (the Military) for application development and I do agree that there are dormit services that hog up your memory / battery even when your not using the phone.
I agree with this dev and his tool: http://andrs.w3pla.net/autokiller/details
I think that he nailed it when he found out how did Android manage memory and the determination it takes in order to "kill" what you don't use.
Now... Do you care to share what you know about the subject that we don't, in stead of just coming bashing and leaving?

Nice. That was my issue though is that some of these memory/battery killers don't show up in the launcher's task killers. Google + and Maps never show up and get stopped and continue to kill the battery getting data behind the scenes because Google wrote them in that way. It is important to at least check if you have bad battery life what else is running with a good task killer like Memory Booster Lite.
i think the best solution for battery life is autokiller, v6 script and titanium..the stock gingerbread task manager aka (the running services in settings) isn't that great...when i was on eg22, i noticed it displayed the wrong amount of ram left and didn't display every single app running in the background..autokiller is able to see every single app running in the background but never kill the programs with (com.google and android.process)...I only kills apps i use like engadget and pulse..when u exit these with back button, they always stay in the background and use autokiller to make sure it's completely killed...never set any task killer to autokill apps, that will drain your battery faster...and they are some annoying 3rd party apps that always run in the background since they are not coded well (imo)..for example, i froze the script manager with titanium after i implemented the v6 script because it kept restarting itself all the time..i suggest people follow RandomKing's tutorial on how to extend battery life, it helped a lot..http://forum.xda-developers.com/showthread.php?t=1106524...i constantly have 150 to 200 ram free with im not running any apps..im on eco5 aosp rom with eco5 (eg22 and eh06 are not stable enough for me)
To be honest, I think you're overestimating the effect these task killers are having on your phone.
Your graph looks very similar to mine when I'm using it moderately, and I haven't installed any task killers. (And, yes, I've got the same Maps, Google+, etc apps on my phone). The only changes I've made are:
- Turning my screen brightness all the way down.
- Having very few non-push syncs.
Today I'll be using my phone a lot as a camera, but I'll try to remember to leave it off the charger one day this week so that I have a power graph that lasts longer than 18 hours.
I was getting horrendous battery life on my new Nexus 7 stock and rooted / custom ROM.
I decided to wipe, install zero apps except Chrome and fire away at the battery. YouTube has streamed 3 hours worth of an HD video and I'm at 72%!!! Nice!!!!
I was using FB and FB messenger, Firefox beta and really that's about it. Needless to say I'll hold off on installing them until they've been optimized with 4.3

Its FB. Seriously. Its a horribly written website with horribly written apps. It sucks information all the time.

I'm sure my battery life would be great with no apps installed too. I'm holding off on wiping mine though, because I'm sure after I root and reinstall my stuff, the battery life will go to crap again.
On my Nexus 7 Google Services has an inordinate amount of keep awake time. So I'm hoping updates will fix the issue.

I've heard people uninstalling Google Services helps. Might cause issues elsewhere though. I think certain battery savers can limit specific apps from keeping the device awake. Im on CM and my device goes into deep sleep quite often. Like 86% of the time.

Better battery stats always helps finding the culprit. I had some issues with suspend_backoff and it seems chrome was the issue for me.

A thousand times THIS.
If you really want FB install tinfoil. You lose notifications, but it's FBs garbage constant notification polling that is keeping your device awake.
Not trying to defend Facebook but.... Its not like fb doesn't have the option to turn notifications off. Chat availability off. Refresh interval to never. Messenger location off.
At some point no matter how bad the app is it comes down to user error.

It doesn't matter. I turn that crap off and while it probably helps, FB is always eating up tons of memory and keeping the battery drained.
I use APW Widgets, setup a Facebook widget, and click through to the mobile Facebook page using Next Browser. The Facebook app has some perks over this but using this method, I know its not leeching my contacts and mobile usage.

I believe you as I've had issues like this too with many apps.
What I don't understand is how two people with same hardware, same ROM, install same app, one will have drain and the other doesn't. For example I have FB installed on my N7 2013 and its fine (at least it doesn't pop up in the usage chart if I don't use it).

Using memory doesn't = using battery,
With those settings the device should idle perfectly. Assuming the rest of your set up is well behaved of course.
While your device is up and running the process will run time to time but it shouldn't cause any noticeable battery drain.
Don't get me wrong I can go on and on about all the stupid things that app does but set it up that way and you should not suffer any battery issues / drainage.
Once the MBA and CEO Class got their hands on Facebook it was Game Over .....
Most MBA's and CEO's aren't well enough educated to run a technically/scientifically based operation .... Look what happened to Gateway, Yahoo, Dell and almost happened to Apple in the 90's before they brought the Brains back ....
Google is one of the few that haven't went that route which is why they are leading the pack on most things. .... As long as the Brains of Google keep majority share and thus control of Googler I'll stay invested but as soon as the MBA and CEO Class takes ovber (hopefully never) I'll dump all my Google stock just like I did with Yahoo in early 2000 .....
Just look at the Damage the MBA and CEO Class did in the late 90's (The wrongly named Dot Com Bust) and in 2008 ..... Mainly because they are too poorly educated to work the technology and their insane belief in disproven Economic Theories like Supply Side that falls completely to pieces in the Tech World ....

does a battery saver app like juice defender ultimate work or it just wastes 'more' battery?, i don't think my battery is all that great but i do have alot of apps installed
anyone installed snapdragon battery guru app?
gonna try to unistall chrome, but i find its the best looking browser interface for the sites i visit
I'm gonna tell you greenify changed my life, my battery life that is. Try it out and you will not be dissapointed.
an app that has not been used in over a day.. after a reboot yesterday should not be in top ten active apps and have near 7000 wakelocks when all notifications in the app are turned off. so yes, Facebook app sucks more than just itself
still. I'm at 22 hours unplugged, 4 and a half hours screen on time and only at 54% battery... I rate that as good

I would have recommended JD a few years ago.. its victims abandon ware for almost 2 years.. (never updated for ICS let alone JB) you are better off having tasked handle the same functions.. or just removing apps that are poorly writted

I haven't had any need yet on my Nexus 7, but I found Gemini App Manager to be a godsend on my Virgin Mobile phone. I can disable all the Intents that apps believe they ought to wake for and just allow them to respond to me actually running them. Much better battery life and more responsive phone without memory cluttered by all the bloatware that believes it needs to run all the time.

I just picked mine up yesterday and snapdragon was one of the first apps I looked for. Couldn't download because it's "not compatible with this version" I'm on stock BTW...

so your saying that the app by default should run constantly in the back ground grab your location any time it wants. THen its user error that they dont dive in setting and change everything so it doesn't suck battery life
LOL yes its user error, now Im off to sound full of myself elswhere
