Dear all,
I just upgraded my tab into overcome 3.1 from my initial GB 2.3 . The reason why i started to discover some issue on my batt usage is within 2hrs it will take off 20% of my batt when i fully charged in the morning.
After which i check on my application - batt use - it show "display" is at 92% on the top and android system is at 2% at the bottom. Whereby when i use GB 2.3 rom, it will show andoid system is at 80~90% and display is at the bottom of 3%.
(Note: i have even set my display to the lowest and set it to Auto mode, some of the un use application i also shut down)
I have started to think should i change back to GB 2.3 or is there any brother outside can advise what should i do to change this situation. Hope someone can help me on this ..... Thanks in advance.

dear all, after further confirmed, my colleagues also having the same problem as my, I was wonder is there a bug in this version as em not sure why the consumption of the battery was so high after installing overcome 3.1
First of all, old ROM had a bug, battery usage was displayed wrong. That is fixed, but they are now working on R2 version of kernel (Reverted lowmemkiller change which may have been blocking kswapd0 from sleeping, resulting in battery leakage).
This last kernel has a new ROM as it's base, so you have to install new ROM first and then full wipe version of kernel.
Good to hear I am not the only one.
Hermes was an awesome rom concerning battery stamina. I hope the guys from Overcome will make this R2 release just as good.

thanks for your quick response.
The latest version of the overcome kernel is pretty good on battery life for me.. the only thing that seems to be wrong is the reported charge level against the battery display level..
Even after calibration its still way off (20%)..

i think you need to perform a "wipe on batt" in cwm maybe can help. Anyway i also discover that my tap below 4 buttons occasionally the light will be blinking on and off during at the standby mode, i belived this also can cus some batt drain off too. Anyway, most of the people are concerning about batt duration especially devise such as non-detachable batt. For me, i use my tap outside most of the time especially during business trip hangging in the train station or airport.... Well, i think we appreciate the overcome team and the rest of you guys to test it out and gain feedback for improment.... cheerss... and Selamat Hari Raya to all muslim people ya.
did you try the tweaks here re: Battery Recalibration and Reconditioning…
http://p1000.teamovercome.net/?page_id=68
and do note that:
battery wipe by itself would not immediately “improve” your battery life. IN FACT, during the first charge cycle after a battery wipe, you might notice a slightly less than optimal battery-life! This is because, the stats have to be rebuilt, which is why after a couple of FULL charge cycles after the battery wipe, when the stats are properly “repopulated”, which is when you’ll see the difference.

yes, i have did that after going through the forum, and today is a second day after the wipe, but i would recognized that if you put the tab in Normal stanby mode, the batt will drop about 1% in about 4hrs since i have started to monitor this morning... well, i will continue to monitor aand post it again. thanks for your advise.
my one on overcome 3.3.1 seems to last at least 1 hr when the battery notification show 0!!!
I have tested my second days after batt wipe, it seem that if we put at standby mode the batt really better then earlier versions, i can notice that last night was 26% at 2.30am and this morning waikup at 7.15am, the batt indicate 24%. (Note : my wifi is on, except BT and GPS is off).
My conclusion for now is that the OC 3.1 batt life is ok and even better when it was in standby mode, however whenever any application for example browsing internet or starting reading news, the batt will start to drain off like 1% every 3min (my estimation point of view).
Hope the OC team can help to improve from here OR the nature of this OC 3.1 is normal on this circumstanses. Cheerssss....
Hi,
I have a SGN and CM10 nightly, and updating daily.
The only bad thing for me in this JB based ROM is the heat and the battery drain (almost can see the energy flying away the battery )
As I have been reading a little bit, I think, and please correct me if I'm wrong, that the KERNEL can change some equipment behavior...
Question:
Do I have to stay with the kernel of the nightlys?
If not, what options do I have, and what are the main differences between them?
If I change it, do I have to re-flash it every time I update to the new nightly?
According to your help... I'LL BE BACK!!!!
Thanks a lot

The new cm10 kernel uses updated Mali display drivers. Currently there are no alternative kernels with these drivers so you're stuck with the stock one.

I guess you have a rogue app misbehaving. I can clearly remember when I had this problem as well: battery drain and heat.
You might install the following 2 apps, to see whether your device enters deep sleep, if you already haven't.
- better battery stats (1.11)
http://forum.xda-developers.com/showthread.php?p=15869868 and
- CPUSpy (0.5.19 beta)
http://forum.xda-developers.com/showthread.php?p=28045183
Then, after you checked "deep sleep or not?", you could go to this thread concerning wake locks&battery life, a very informative thread by ahalford - and he is being very helpful!

I picked up a Galaxy Note the other day to mess around with, and have noticed that the battery life isn't fantastic.
I'm running Slim Bean 4.2.2 build 7, and NX OC kernal. The only relevant settings I've changed in the kernel utility are the clockspeed (from 1.4 to 1.6) and the governor (from Hyper to SmartassV2). Battery is stock.
Here's an Imgur album with screenshots of everything I think you'd need to see: http://imgur.com/a/fAUR7
Now, am I missing something, or does this look right? Should 'Android OS' be using that much battery?
Thanks a lot in advance for anyone that can help.
What's your screen-on time? To check that then go to battery and tap the screen. (report when the batter is nearly dead - below 5%).

Whoops, I missed that.
At the time of those screenshots, it was at 1 hour and 15 minutes, give or take a few minutes.
Ran the battery down playing some games. Updated screenshots are here: http://imgur.com/a/16ZRk
OK, so first and foremost then playing games will use a lot of battery. Usually you can't get more than 2h of intensive games. However the android OS usage is very high, install Better Battery Stats (search on XDA) and post the result. Also did you perform a clean install? As in did you perform the following wipes: system, data, cache, dalvik cache, preload?
The battery seems fine. It is normal with high Android OS. Same on my phone. Beanstalk + NX kernel. I managed to get around 2-3 hours of on screen time with gaming.

That's good to know.
I just bought myself a 7000mAh battery from Hong Kong, so I shouldn't have any issues with battery life now.
Do please keep us posted with how the battery performance is. Could u post a link if you bought it online..
Hello,
I've searched the forums about battery drain problems regarding android phones in airplane mode but each subjects seemed different to mine.
I own a Samsung Galaxy S3 LTE i9305 under Android 4.3.
The phone is rooted, Greenify installed, hoping saving battery life but...
I've tried to do a full data reset + reinstallation of Android 4.3 official, with no success.
I've done the folowing experience 3 times with the following similar behaviour as last time :
- Phone fully charged before to go to bed, Airplane mode activated.
7 hours later :
- Battery is at 80%
- 0 minute in deep sleep, all the time in awake state.
Several behaviours noted by Wakelock detector and Gsam Battery Monitor :
- Device Idle and androidOS consumed 80% of the 20% used
- Misc processes seem to have used a lot of battery among them :
- AlarmManager
- PowerManagerService.WakeLocks
- KeyEvents
I'm including screenshots to illustrate all this.
If anyone has been thru this problem I'd be glad to know how to solve it.
Thank you !

Hi,
I do not have the exact same problem, but my phone drains battery more than often. With wifi, mobile data etc turned off, i have ~10% of drain overnight (7~8 hours). But my phone does enter in deep sleep and battery stats shows me nothing weird (most of battery is being taken from phone iddle /standby cell), it is driving me nuts! My wife have the same phone as mine, same firmware, same system apps, the only diference is mine have the new bootloader, but her phone drains almost half than mine. I'm now reinstalling the firmware with the exact same steps i did in her phone and if someone want i post some screenshots later.
Did you tried installing some custom roms out here who have not all the system apps the original package have?

I am using 4.3 Alliance Rom with boeffla kernel. I had the same problem with battery drain during airplane mode. While I was at work with airplane mode on, I lost nearly 20% in one hour. Because of it I switched to 4.4.2 aosp rom "aosb 1.3.0. Probam" (meanwhile there is 1.3.2 published) but there I had music stuttering and camera issues, but perfect battery life. Because of the problems I decided to go back to 4.3 and gave Alliance Rom another chance. And now the battery life is wonderful like on 4.4.2.
Maybe try the same way, first to update on an aosp rom with excellent battery life and then go back to android 4.3. Maybe this will solve your problem, too.

Hi,
By any chance, do you have XPOSED framework enabled and do you use for example Wanam Xposed module ? If an option like "Turn on screen when unplugged" is unchecked (ie if you don't want your phone to wake up after you unplug it from USB), you may encounter battery drain. It seems that sometimes the phone doesn't enter in deep sleep if the USB cable is unplugged from a PC in this case. I have this kind of battery drain and since I've checked "Turn on screen when unplugged" option, no more battery drain after a reboot.
I'm not sure but you must give it a try as it worked for me. No problem so far.... I hope it will help.
Hi and thank you all,
I'm taking good note of your advices.
I did install Xposed and Wanam. I didn't pay attention to this option and since then completly reinstalled 4.3 official ROM. Battery drain vanished.
I now have the phone going to deep sleep normaly.
I've been reinstalling all my apps slowly one after the other, and didn't try yet to reinstall Wanam Xposed, as I know it modifies the system relatively deeply.
But the envy is here and I think I'll install it again. Ok, let's go, I'll do it tonight. I'll pay attention to "Turn on screen when unplugged" option and will ensure it is checked !
It's worth trying, though all these battery draining problems seem mysterious...
I'll post a reply in a few days with the results...
By the way, I installed Agni kernel wich uses Boeffla engine too. After activating "Extreme battery save" mode, the battery life has doubled or so. I'm happy about this.
Thank you again, and let's see how xposed wanam behaves...
GREAT.

I'm new to posting on XDA so I apologise if i posted this thread in the wrong section.
I've flash the ROM with nano Gapps about 2 weeks ago and been clearing cache over time and i still can't get above 4 hours SOT. I personally use a dark theme (substratum) throughout my apps and system apps, Bluetooth and NFC are always disabled and location is set to battery saving. I can't find the app which is hogging my battery. FYI, I rock a similar setup on oos 4.5 and easily it lasts 6 hours of SOT. However, i do think its the Snapchat application but it's an important app to me. Any suggestions ?

Hey,
If you could include a few more details such as your kernel (if you've flashed one) or PA version, whether you're coming from a clean/dirty flash and other additional information, that'd be great, so the community could address your issue better.
Also, you may want to check wakelocks and battery health (NOTE: not Battery Life, Battery Health).
If you're on PA, you may want to revert to OOS 4.1.X, and check your battery life and SOT.
Snapchat is a universally known app that has its' fame for being battery heavy, so if it shows up as a heavy battery user, that's because it is. The reason is, because it has heavy use on the Camera, GPU and mobile network or wifi.
Cheers.

I've not flashed any kernel or any other ROMs before and I clean flashed PA 7.3 which is the latest version available. I've also flashed arter97's F2FS boot.img. Wakelock details are provided in the screenshot attachment as well as the battery health condition data provided by Ampere.
I've not had any issues with Snapchat on OOS though :/
Note that I didn't greenify it too.
Edit: I'm having difficulties to post the screenshot
