Hey,
I have lately flashed CM10.1 nightly on my GT-I9300 and am experiencing high battery drain (twice-three times what I had before), and get over 1%/h over the night when all is turned off.
I have read a lot about fast battery drain reasons, but couldn't find an answer to mine.
I've downloaded better battery stats to check for any abnormal activity, but it seems normal to me (dump attached).
Note, I've installed the cm10.1 straight from my internal memory and I do not have an external SD card.
Also, from the dump file it seems that the phone was mostly in deep sleep mode and I see no reason then why it wouldn't just drain at 1-2% per 8h.
Thank you very much in advance!

I was able to improve battery life by turning off haptic feedback. Now I'm getting about 8-9 hours of moderate to slightly heavy use, which is much better than the four hours I was getting before.
Lower your brightness settings, screen is to blame the most.
Turn off gps, data, haptic.
Install Greenify, (requires root) to lower the battery usage of the phone by greenifying the apps that youre using.. However it works for me

Yes, another battery life thread but this one is a recent development for me.
I bought the phone on release day so I have some track record with it. I have not had any trouble with my battery life and have always been able to make the day on a charge. However, recently the Cell Standby and Phone Idle has been sucking my battery dry MUCH faster than in the past.
I unplugged my phone this morning and headed out to work as I do every day. I grabbed my phone at around 10am and saw that the battery was down to 58%. I checked that stats and this is what I saw:
Battery Level 58%
3h 46m 59s since unplugged
Cell Standby - 27%
Phone Idle - 20%
Display - 20%
Bluetooth - 11%
Android System 9%
Other stuff that was nominal >5%
Is this normal? Why would Cell Standby and Phone Idle suddenly be draining the battery when it didn't do it before?

More info on your rom? do you have Wifi calling APP? If you have a custom rom, did you do the battery recycle?
Thanks for the reply...
I am on the stock ROM (rooted). I am not ooposed to flashing a new ROM but I definitely don't want to DECREASE my battery life which is what I have seen occurs with some. Are any of the custom ROM's proven to increase battery life?
I don't have Wifi calling and I haven't done the battery recycle. I fell out of 'tweaker' mode a while back and have just been using the phone. I don't think I have even installed any apps since (or before) my battery life seemed to change. About the only thing different is the Market but I don't think that's a problem.
I just looked and it's down to 38% in 6h 24m and I haven't even touched it. It's rediculous. Something is like a parasite in my phone and I don't know what it is. The only thing running in the "Active Applications" is Launcher Pro but that was one of the first things I installed when I got the phone.

Nero V3 is great for battery life. Also check if you added some apps in the past few weeks. Might be some background sync process taking too much of battery life while in standby.
i've had this issue before and i've found that it was always a rogue app. your best bet is to start uninstalling or freeze them in titanium to find the one that is screwing you up.
one app that was my latest standby hog was beautiful widgets.
Thanks for the tips! I will start removing some apps and see if that helps.

I am not up to speed on the various ROMs. I will go start reading up but is Nero V3 fully functional (camera, GPS, etc.)? I was keeping track of the progress on all of the ROMs but there are now so many and they are updated so frequently it's tough to keep up (at least for me).
Thanks again!
Oops. Double post.
i'm sure it's an app that's causing that. I think a stock rom won't drain that too much.

It may not apply, but I've also noticed that beautiful widgets is a hog.

I am having huge issues with my battery on my galaxy s2. It drains really fast, 60% over the last 15 hours this night when the phone has been idle. This has been an issue for about a week now; I cannot seem to find a solution? I have tried various roms, wiping and doing a clean install, but the problem continues. Currently using lightening rom 3,2.
Do anyone know what can be causing this battery drain? Is the battery defective??
What apps do you have installed?
Sent from my GT-I9100 using XDA App
That is quite a drain I can see there. The drain might be caused by having too many widgets or having too many applications open. If you plan to put it on standby, do close those apps that are not important to you.
Have you tried rebooting?
I have a stock lightening rom 3,2. no apps installed, except titanium backup pro and opera mobile. I have frozen all kinds of stuff in titanium to try find the cultprit, but without success. As you see, no apps except andoid OS is running. Same drain on villainrom, lightening. Don't know what can be causing the error. Is there some way to check if the phone or the battery it self is to blame?
Try with screen on - normally I think that should run for 6 hours or so. Using that as a reference, you can check to see if the energy stored in the battery is normal. It doesn't look like your OS is staying overly active to me.
Hi bjorninge,
Every time after you flash a new ROM you should calibrate your battery.
Get the app "battery calibration" from the market and follow instructions and please report back whether you can achieve better performance.

I have a similar issue, as was the same with my captivate. I have stock ROM on my GS2 though, the way I got it out of the box pretty much. Android OS takes up most of the battery usage. I don't know what it is. Widgets updating constantly? The constant syncing from Gmail/push email?
Well that's surprising! Awake and Screen On bar is quite low and totally synchronized, yet 60% drain, now I gotta say it's weird.

Unfortunately, I have the same issue as you've described above. I am running on stock KE2 kernel and the battery drain is quite a lot. The 'Android OS' is always consuming a lot of processor time on standby mode.
This needs to be fixed A.S.A.P.!
Download and install the app BetterBatteryStats from Android section, it is a very useful app which will show what Awaking the device from deep sleep and processes too. For me, it was the damn Latitude stuff going on background and wasn't letting the device to go to deep sleep.

Thanks for the tip. I have downloaded the app now. what spesifically should I look for?
You just look under 'Wakelocks' and you will know what apps are causing the Awake, then you could take further steps.
Regards.
Would be great if you could look at the screenshot and tell me if something is wrong. Also, after the battery calibration, I've "only" lost 26% the last 7 hours mostly idling. I don't see anything abnormal in the screenshot I provided :/
Well nothing is wrong imo as everything is very low. You should check those which are using more than 10 mins Wakelock, some seconds doesn't matter actually. And you can post any query further to the original thread of this app, here,
http://forum.xda-developers.com/showthread.php?t=1179809
Regards.
OK, So I'm now back to 12% battery usage (from 100% to 88%) with 17 hours and 30 mins on battery, which IMO is normal.
What did I do? Well, I removed the battery and put the rest of the phone into the stove for an hour on 50-60 degreed celsius. My 98% android OS usage is gone and the battery works as normal .I also had problems with the phone constantly going into "car mode" which is now gone.
I got some tips around the internet that my issues were all related to moisture on the inside of the phone.
Hey guys,
I have been running unnamed rom lately, but on any other rom including stock. My battery lasts for like 8 hours with little use and 4 hours with moderate use. When I see what is draining my battery it looks normal as the display uses the most, but I only have it at 30% brightness most of the time I have insurance should I see if I can get a new battery? Or any other tips?
Can you post a pic of your battery usage?
Have you tried to calibrate the battery yet?

Many things could cause battery drainage, such as oc-ing. You could find the original Samsung battery on eBay for a cheap price. Before buying one, try doing the following:
Clear OC/UV settings (i.e. put to defaults)
Download Battery Calibration by NeMa (on the Play Market)
Charge your phone and wait until it reaches 100%*
Tap on "Battery Calibration" and done
Once calibrated, use your phone as you normally would until the battery dies. Only when it dies you can charge it. You can charge as you please from then on.
Note: If it does not reach up to 100%, go to CWM and clear battery stats.

Which other firmwares? Anything UCKK6-based has known documented wifi drain issues.
The usual applies - look in battery statistics, use BetterBatteryStats to hunt wakelocks.

never tried the battery calibration?... does it actually work or no?
have you installed any new apps recently? those apps that use a lot of apps in the background are a pest to your battery life as they usually won't show up in the battery monitor. try disabling your data when not in use and see if that helps. if the current rom you are on does not have a toggle bar with data use the "data enabler widget" by Farproc.
finally found a thread on this issue after posting
http://forum.xda-developers.com/showthread.php?t=1748301
sorry mods, pls delete
Me too ... it's driving me nuts.
I am experiencing this. My battery life is horrendous. Even when I barely touch the phone the battery drains extremely quickly. I have already rooted the phone with a few different roms with the battery setting "fix" to no avail. I'm on at&t. I have disabled wifi and gps. I have tried to use both the stock app killers and 3rd party ones recommended by these forums. My battery monitoring apps (both stock and 3rd party) consistently attribute the battery loss (always more than 90% of battery use) to an android system app. The android system app or file changes from day to day seemingly randomly. Files have included: UltaCfg, com.samsung.app.playreadyui and security storage.
Any help will be extremely* appreciated. I love the phone but it is nearly useless in this state.

I have been experiencing some serious battery drain issues. Looking at my battery stats, "Android System" is responsible for over half of the drainage. These are the only apps that run constantly besides those which the phone requires to operate:
- SetCPU
- HDWidges
- The Weather Channel
- LBE Privacy Guard
- avast! Mobile Security
other phone info is in sig. Any insight/advice??

I am draining my battery as quickly as I can (streaming Netflix through 4G LTE with max screen brightness, max overlclock w/ performance gov) and then i'm going to power off and do a full recharge. this seemed to have fixed similar issues in this thread:
http://forum.xda-developers.com/showthread.php?t=1756776
let you know the results.
edit: suppose i should say that i was not experiencing this issue until i updated KT747 this morning.
this is what i did:
1) drain the battery completely. let the phone die.
2) charge to 100%. do not power the phone on until it is completely charged to 100%.
3) when i powered the phone on I was at 99%. i plugged it in and it went to 100% in about 2 minutes.
this seems to have completely solved my problem. the android system has gone from using 57% of the battery to 6%. it seems like the kernel i was using vastly overestimates the percentage of the battery to allocate to the android system until it "learns" the capacity of the battery

I am also a Telus user. I had big time battery drain issues even with trying everything: enabling power savings mode, running Juice Defender, using wifi more, using darker wallpaper, keeping a closer eye on syncing operations, screen brightness and some other stuff.
After about 10 days I went back to the vendor (Futureshop) and convinced them to give me an exchange on the battery. They have a 14 day return/exchange policy for cell phones if you are not completely satisfied. I took some screenshots to argue my case. Thankfully the rep said ok and further explained how much power an AMOLED screen uses. I really didn't want to convince him that I am quite informed on battery drain issus and took the new battery and ran!
Conclusion is the new battery is so much better it's like night and day. I have the capacity now that others have been raving about.
If you can exchange the battery, do it. Then get the new battery and charge it up fully first thing.
Well recently I bought the Beast S3.
Now I installed this first Kernel - CF-Root-SGS3-v6.4
And CM9 rom, was working great though there's one problem the damn battery drain is like being raped evey 5-10 mins if not less I loose 1-2% battery.
Now I though it might be the Kernel so I switched to Siyah-s3-v1.5.3-CWM, no go still the same result.
I changed my Rom to CM10, same result.
Here's a Screenie of my device (In Attachments)
Could you help out a little? I've checked and not sure where is the issue, and I understand that super huge screen consumes allot of power but even if I set brightness to 0-25% I get the same result...
Most battery issues are caused by installed user apps. Install Cpu Spy for cpu deep sleep issues and Better Battery Statts for locating apps that show unusual activity`s and drain the battery.

This battery drain percentage looks normal to me.
Sometimes I lose 5% without doing anything, even if I have a perfectly cleaned rom.
