[Q] Battery drain during night hours - Galaxy Note II Q&A, Help & Troubleshooting

Last night I had a weird battery drain for the first time... it went down from 100% to 76% in 8 hours of sleep... looks like the call app is the reason... I'm on stock without root.
Have a look

Reboot the phone in recovery, clear caches and reboot. That should solve it mate.

Maybe someone used it while you sleep.

No, the screen was off all nighty but the phone was awake most of it.

Do you use Perseus kernel ? Same happened to me a couple time while using it.

I got it too this night. Had 48% when I went to bed, 7 hours later battery dropped to 19%. First time I get that, and also the phone app that's been eating the juice. My device is not modded at all.

Android System at 53%

Why is it so high?
Ever since the last OTA update it seems to be worse..
I have downloaded *but uninstalled* a non market app.. is there a way to scan to see if there is a rogue app hiding?
I can't remember what I was running on a touch wiz ROM.. but I'm using Task650/ktoonzsez aokp ROM and android system is only 6%

Edit: there is an app called carat on the market that will take a few days but will periodically monitor your phone and apps and let you know which ones are battery/system hogs or problem makers

I was on a touchwiz ROM and getting that too. It made my battery life complete sh*t. But I've been running AOKP with no problem

I believe there is a cell standby zip you can flash to fix that.

Android OS battery drain CM10

While sleeping my phone was connected to WiFi and not touched for 7 hours or so, but my Android OS says it was awake the entire time. I'm new to CM10, but on TW my biggest battery drain was screen and cell standby. Any ideas?

I had the same issue then I realized that for some reason my proximity sensor was not turning off when I turned the screen off which may have had something to do with my phone not sleeping...I reset my phone and the sensor turned off and overnight I lost 3% battery.

I am on cm10 but all I had to do was reset the device and the sensor would be off once it rebooted...battery life still isn't quite as good as stock just yet but I can easily get through the day on one charge with about 4hrs of screen time...where did you find cm10.1 for our device?

100% awake time, horrible battery life.

Okay guys, I hope this phone gets better battery life than 8 hours, and I'm not hard on a phone at all. Any ideas on this? My wake locks are horrible for some reason and I'm running the synergy r71.

Install BetterBatteryStats. Great tool for identifying what's killing your battery. You may post some screenshots if need be.

Deep sleep battery will help alot as well your at 49% so if you think of it by the time you are drained to 10 youll probably have about 18+hrs of battery

Yeah alot of people freak out when tbe phone gets to about 50% they don't realize that thats half the day usually. ... and it also depends on how long your last flash was it takes a few days forvthe kernel to settle.

Depends on usage anyhow. You should get 6+ hours easily on any stock based ROMs with any sort of usage IMO. Without any of the power saving stuff that is. The first phone where I've never really used power saving option at all
Okay Hmm i use Stock

So that you can get rid of any rogue apps/processes that might be sucking your battery. If it still persists - then you'll know that it's hardware issue, not some rogue apps.

I thinks it automaticly went to deep sleep as soon you put the phone to sleep, maybe you got some apps that keeps awaking your phone.
In my case I change the kernel, you can try it if you want might help you

I'm using stock kernel. deep sleep works on both stock and custom kernels. use Wakelock Detector 1.5 to check what things that keeps ur phone awake, and greenify them (if possible, use greenify donate)
