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?

The only thing I can think is that something I was doing when I used the phone before bed, kept some sort of process alive all night.

Great one! Less than 10% drain overnight, 30% per day with moderate-light usage

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
my galaxy w is rooted but not flashed, and suddenly it became so hot and draining so fast.. can anyone help me ? is it leaking ? do i have to replace my battery ?
There are programs that check for apps that cause memory and battery leaks.

Check if its bloated. If you can't see it well, take out your battery, put it on a table and spin it. If it spins for more than 15 seconds, then it is bloated. You will want to change it. And yes, we will require a screenshot of your battery usage

Don't take that as being 100% correct.
I have had batteries reported as healthy when in fact they were starting to show the smallest amount of bloating and starting to fail, which caused fast discharge and other problems like rebooting when forcing the camera flash, sudden drops in battery charge level etc etc...

It´s all your battery programms draining your battery. Yes they are draining battery too and if you need so much programms, don´t wounder your battery is drained so fast.
So rather than using all that battery apps better check what else is draining your battery.
sorry for late reply, but thanks for all of your suggestions..
gonna post the battery usage sooner when i got 10 post
Hey guys, so it's turned out that my battery is leaking, now i have replaced it with a new one, but it's still draining so fast. So what do i do ?

Greetings everyone!
I'm facing battery issues using Gimmeabreak 2.0.6, but (maybe) read somewhere that is a cyanogenmod related problem, but I still can't find a way to solve this problem.
I got huge battery drain by screen from (40% to 50%), with auto backlight, 1 min shut off.
Battery is 2 months new, cleaned cache and dalvik cache from recovery, recalibrated battery.
Is a rom related problem or a cyanogenmod problem and there a way to fix this?
Thanks!

Thats an awesome rom by an awesome developer.. If you concerned about battery use Gimmeabreak 1.1.. Best battery backup and most features as 2.0.6... Dirty flash over it...
Thanks, I'll try that later!
I think that for most ROMs, custom ones at least, the biggest battery drain is often from the display/screen. I'm currently using Jellytime 4.2.2 R11 and my battery drain from the screen is ~40% but I still get a decent 15-18 hours of usage daily before recharge. You could try saving battery life by disabling other features such as Google location reporting and turn auto syncs off your accounts
Hope my input could help :good:

The only other things I could think of would be to:
1) Wipe battery stats via recovery
2) Recalibrate the battery (but I see you've already done that)
3) Use the app BetterBatteryStats to find out what apps are keeping your phone "awake" cos it could most probably be just an app causing battery drain.
4) Worse-comes-to-worst, buy a new battery?!

eheh! Done everything, used another battery, still no solution!
I think I'll wait for a stable kit-kat rom!
Same case here
I have the same battery drainage issue. The battery drains from 80-70 or 50-40 in matter of mins or sometimes seconds when the screen is on. I guess its something to do with the CM ROM. I also use Greenify and i've hibernated most of the apps that relies on GCM.
Any good battery saving kernel's for CM10.1?
Wipe battery stats via recovery seems to help a little
It seems like a normal drain, I have the same drain for screen, is pretty big for the battery...

My battery is 2 year old, normally the screen uses about 50% to 60% with also auto and 1 min. I think your battery drain is not very normal.

I think you should consider replacing the battery after 2 yrs. It.s cheap, at least on ebay, you can buy one of 2-3000mah. I did so and the problems stopped, but I didn't had such a battery drain. Try a different rom, I.m on JellyTime R10, and I find it most stable and no battery drain.

Normally the battery can hang on about 1 day for a regular use, and I have 3 backups, after this one dead I will use another one. After randomblame release the stable 4.4 I will try. Maybe it's a cure for all problems, haha

I'm thinking if it's not because of the battery life or the ROM, maybe it's some apps are using too much resource. I've tracked my CPU usage, one weather app was always using about 20% CPU.

Sorry to bother you, bit which brand and model of batteries do you buy and use?
I already searched many and many opinions, reviews, etc...
And all say the best ones are OEM, Mugen and Anker.
I really want the brand with the best battery life 100% to 0% , bit also the best life and reability to end of life (years) based onde old users that buyed.
And best quality too, this is with temperature sensor and protection overcharche, trust legit laws, that things =D
Which are your recomendations guys/girls?
Thanjs so much
PS: sorry errors of keyboard correction prediction, and english not my native language. Lol.

It was just some batterys without a brand, haha. I think it's not gona be a big problem if we use a third party brand, just don't use too cheap one I think. I'm using it even with CPU overclock to 1.5GHz.
Apologies if this seems well travelled path, and I've certainly led a lot over the internet. But I just wanted to describe my issue and see if I've missed anything!
I've had chronic battery issues, and had a spare and I'd swap them in/out but I came to conclusion that wasn't great as it may not read battery stats well doing two different batteries. I was getting less than 12 hours between batteries. So now i have Powerbear 6500mAh battery and have been using it for a week. Apart from a heavy usage day I can now get 24 hours out of it. Superb.
Then as if by magic, trouble returns! The battery drained 11% overnight in seven hours. That's in airplane mode. 11% of a 6500mAh battery! Battery stats shows nothing has used battery in particular, just phone idle. Wake locks there was nothing significant. Now 5 hours later it's dropped another 43% with not a lot of use, just web and some maps.
Things I've tried:
Making sure the option to store activity logs is off.
Location turned off for all but most vital apps, like maps.
No automatic syncing of anything.
Greenify - and I shut down anything I can.
Wakelocks - ensuring nothing is abnormal, got rid of CityMaps due to excessive wakelocks.
Airplane mode at night - no cell, no wifi.
I rooted and reset the OS about six months ago, so that is my logical next step... but I'd rather understand what could cause 11% of 6500mAh to be drained by doing nothing!
Any thoughts of what I might have missed?
Stats: LG G4. LG-H815. Android 6.0. Build MRA58K. Software V20g-EUR-XX.
Thanks

What root method did you choose? SuperSU or Magisk? With Magisk my phone was hot (~70C) and got only 1.5h screen time, when i switched to SuperSU, it was gone.
Install GSam Battery Monitor app from the Play Store and see if it helps show you what's using up the battery.
I know you are not going to like reading this but
I don't use these extended batteries for a reason. Phone wasn't made for it.
Try your original battery
These extended batteries are also known to crap out after 500 charges
Use battery monitoring app to help you determine what's happening

I removed it as it never provided me anything worthwhile. I think it used to just say Android used the power or something vague. I can reinstall it, but there was never one specific identifiable reason I remember that.

Then I have to put up with a phone that won't last 6 hours, which is what led me to get additional batteries and now the PowerBear.
That said the following night, it used about 2% overnight... so erratic to say the least! And I have 59% left after 10 hours use. It's just the randomness the other day that spooked me. I did learn it was low on disk space, could have that caused that particularly bad event?
Did you try switching kernel? I can suggest you to try Imperium Kernel, that will reduce the system's usage. Other than this i have no idea. :\

idk what's the cause but that's a huge battery drain. Did you tried apps like greenify ? They freeze apps that may drain your battery. If this doesn't change your battery life, well it's time to change your battery!
