Check out this image I took. Android OS takes up a lot of battery and uses cpu active for nearly 4 hours...
How do i find out what is draining the battery?

Install GSam (don't forget to remove this later, it drained my battery itself) or buy Better Batter Stats.
See if you have wakelocks. If you have, some apps are preventing phone from going into deep sleep.

Go to BBS-> Click "Other" and check Kernel Wakelocks, Partial Wakelocks, Processes etc. to see what eats up your battery.

OK thanks Will do.
One more thing. Is it safe to have BBS running all the time? Will that drain my battery fast?
Yep. I have it running. GSam drained my battery, this didn't.
I use BBS and haven't uninstalled it once for many many months. It doesn't drain much battery life, so it's OK to have!
If you want, you can post your findings here and maybe someone can help you identify what problems you're having.

Yeah, that's another thread about battery drain overnight. With some screenshots.
ROM is AOKP b23, kernel s Trinity (tuna).
Sometimes it's about 20%, sometimes only 10. And rebooting phone (maybe with wiping battery stats) just before the night is helpful - then I get about 4-6% drain in 8 hours sleep time. And the phone isn't awake at that time (as you may see on graph), it's deep sleeping.
As BetterBatteryStats and SystemPanel tell me, it's system processes that use much of the battery at that time - few 'kworker' ones. I've searched the forums for some time, but still can't find a good explanation why they drain so much, nor why rebooting helps.
1) change kernel - yeah, I know, I can try that, but with stock kernel I've had the same problem - so I try to find the root of it, not just slap a few different kernels and see which one works better.
2) reboot every time before sleep - well... that's just isn't very convenient and weak way to deal with the problem.
See attached screenshots for further info.
So, any clues about what I can do to improve the situation?

Other than that, I couldn't find any relevant answers... perhaps a runaway system process... I'd recommend switching kernels, as this issue is known and yet unresolved. Seriously though, battery stats reports it using 56s, so is it really a major problem that is causing battery drain?

I'd check that out, thanks! Yeah I know that it's a known problem, but still can't find any good solution for it...
Well it's the process that uses MOST of the system time during that period, so I guess it's enough to cause a drain. And also, there're multiple kworker processes - each may use a bit, but together they get enough for 10% overnight drain.
Which kernel would you recommend to try next? Franco? Seems pretty popular.
Edit: Seen both of these posts, no good solutions anyway. Will try another kernel, then!
I've had great results with Faux123 and I'm just now experimenting with LeanKernel, which is working well so far (wakelocks nonexistent).
I get the kworkers appearing in system panel too, but it doesnt actually effect my battery life. I lose 4% overnight but they show up in system panel.
Also their percentages never add up correctly. For example system panel shows maybe 1.3% cpu usage in total. But when i click thru to the system processes list, the sum of all kworkers exceed 1.3% by a good amount. So i always just ignore them.
Hmm... So maybe they aren't the root of the problem.
Anything else? Maybe battery need to be calibrated, like charging to 100, wiping stats, then discharging to 0 and again charge to 100?
What's really weird is that excessive drain occurs only with extended no-reboot period. Ie, If I reboot just before night drain will be 4-5%...
Check this out. Normally I get about 10% drain overnight, look at what happened last night..
Completely annihilated the battery, everything turned off.
Anyone have an explanation?

Sounds like you may be worrying about battery life too much. If this is worrying alot you may want to get an iphone. The 1750 mah battery is only rated at 10 hours. Lower your expectations about drainage per hour. The phone is constantly pinging cell phone towers to find the best signal possible even in deep sleep. That is the bulk of your drainage.

No thanks, iOS is too restricted for me, and I like Google hardware better (I mean revised by Google, not manufactured ofc)
Yeah, I know, but that's 10 hours of USAGE. And I was getting much differentiated results in the same conditions (like <10% one night, >30% other) - that's what was worrying me.
I don't expect it to last whole week or anything, but 30% of power lost in one night when it's just on the shelf doing nothing (not even connected to wifi) - that's absurd. About 5-10% is ok, I guess. That's what I was getting with my Transformer, anyway - less than 1% per hour in sleep mode with wifi off.
Exact same problem. I'm on imoseyon's kernel. If I reboot I lose about5% over night. If not, about 30+. Some app is waking some system process up that is chugging away with the CPU. If I lay it on my bed our some other insulating surface, it is warm. Yes, my phone is entering sleep mode, no app doing wake locks, just kworker going nuts.
I am using samsung galaxy s2 and i am getting the kworker battery bug too. about 15% overnight which sucks.

Same happening here, but only after flashing the latest CM radio. I guess it might have something to do with that.
link i know it will help you,and let system go into sleep
hi guys, i visit the links posted but i'm still problems with that. Using watchdog app i notice that al least once a day it show me warning message about high use of cpu. In my case the process is kworker/u8: (here there's a number from 0 to 6)
My question is: what specific process causing that? There's a way to know it? I ask it because i don't think is battery releted, cause battery is very good, excluding for the monitor usage which is what consumes more...
I know that this is a really old topic but seeing that there's still at least one fresh enquiriy i thought i'd chime in...what in effect may indeed help you is wiping the cache (it did help me on several kworker/u occassions in the past). To do so you have to access the respective menu by booting your tablet while pressing the up volume rocker and the power button simultaneously. Hope this helps
First, I apologize to veterans who already know this......but posts about battery problems are all over our forum section.
So.....2 things I personally think work best to solve battery draining issues.
1. GSAM from playstore. It will tell you what apps are draining your battery...the top of the app list will be your main culprits. Then you need to find out why? You can check what apps are waking your phone and for how long. Gsam can tell you a lot if you play around with it and see what it can show you.
2. Cpuspy, also from play store. A simple yet easy way to see if your phone is deep sleeping. Deep sleep should pretty much be your total up time....minus screen on time. Roughly. If it isn't, or you have no deep sleep time.....back to gsam to find out why.
Once you narrow down the app culprits ....then you can search on why.
One last huge thing I personally have done for a long time now....reboot after you unplug from charger. Every single time. This used to be a fix for not getting deep sleep....and I think it still is a good practice.
That's it. 2 apps and you can post your battery draining questions with a lot more info than simply saying..."hey....my battery life sucks."
Cause 9.5 times out of 10.....it has nothing to do with the rom you are using. Usually anyway.
Good luck!!!
Sent from my cellular telephone
A couple other things.
Comparing our total battery time with each other is pointless and meaningless. You can drain your phone from 100 to zero in 3 hours playing certain games, or it can last 30 hours cause you barely touched it. The only reasonable comparison is screen on time. Period. Tho it can alter greatly as well. 2 hours screen time on a 3d game, or 5 hours watching movies. 3 1/2 mostly texting and browsing......but still, its a better way to compare.
Gps is a battery destroyer. Some people leave it on...and certain apps will use it whenever you open them.
Screen brightness is a huge factor.
Task killers usually do more harm than good. Personally I only use greenify, and only for apps I know drain batteries a lot. Like maps. If maps is part of the rom....I convert it to a user app with titanium backup and greenify it. Canada's weather network app is a battery hog. Greenify. Basically anything that tops my list with more than 10 percent in gsam gets greenified. My wife used to use Facebook app....I got her using the browser. The app sucked her battery and data sometimes. No....no notification now, but she's on it a lot....her eyeballs are her notification.
Juice defender....great for very light users....a battery waster for medium to heavy users. Turning wifi and data on and off 200 times a day will kill more battery than it saves. Ever see the amount of times juice defender wakes your phone? LOL. I got as high as 1000 before I deleted it. Gsam told me that!

Thanks for this. The thread is a great set of tips and much appreciated by a noob like me.
You mentioned TWO apps. One was gsam. I assume the other was related to #2, deep sleeping. But, I didn't see the name of the second app. What was that? Or, did I misunderstand?

Gsam resets when you unplug it, but statistics stop when you plug it in....for any doubters.
Yes....6+ hours only on charge, but with almost constant use this morning. Peek at the screen on time tho.
Do you feel the paid version of gsam is worth the buy? Or, is the free version sufficient?
EDIT: Sorry. Should have read further down the GPLAY description. It appears the pro version primarily just adds better tablet support.

Definitely a good way to go....keep gsam backup in titanium backup....restore it if you have an issue, then freeze or uninstall it again!
I don't mind the drain and run it 24/7 in case I get the odd issue....like phone process getting stuck in memory after a call. Happens now and then to me....my battery will plummet like 20 percent in a couple hours....I click gsam....see it, force close phone and all is well again. Gotta get thru my 10 hour work day!!! Lol

To be honest, I gotten quite tired looking at the battery percentage. It always gets me SO MAD when I see it start going down from 100 to 90 in a matter of seconds, but the battery icon looks the same. I know it's a placebo effect to turn off the percentage, but it helps to some degree if you're constantly worried about your battery lasting long, like me!

Honestly, I don't touch my phone much at school. Teachers and Deans are more vigilant this year so less texting for me. :/ On a full cycle, I'd say around an hour and a half or 2 hours. If stock had the ability to use the volume keys as track forward and back, it'd be less. That's what I miss from AOSP.

It seems you have 78% Battery left, after 16Hours 11Minutes 32 Seconds Uptime, giving you approx. another 48Hours at your present consumption. This looks reasonable to me for the LG G3.

There might be an app draining your battery. I use better battery stats to find which app is keeping my device from deep sleep. (Its paid app but I found it on the internet. Can't share links obviously)
For me today isn't a good example as I changed kernels etc but this is what u should have a look at too in settings. If your device is awake the whole day some app is preventing it from sleeping. I got 5.5 hr sot b4 I charged and that was with alot of snapchat
So overall my deep sleep was ok but apps like spoifty kept it awake.
Also the one in better battery stats is only the last 20℅ of my battery life. Didn't get a chance to do my sleep lol I was using it alot today.
