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
I have had very battery life for some reason (dies after 6 hours of light usage). I replaced the battery with a galaxy s II OEM battery which is also 1850mah. I also am using every battery saving root apps on stock 4.2.2. Any reason why? Maybe water damage since I got this from eBay?

Hi Im also having a similar issue. the way i regularly use my galaxy nexus the battery usually last 4 - 6 days. after one recharge i am loosing 5 - 6 percent an hour . I am currently running 4.3.1 on a yakju (previously yakjuux) galaxy nexus . my phone has worked fine since i bought it a year ago and the battery is just under 2 years old (Manufacture date is 2011.12.18) should the battery really be dieing this fast after one recharge?

Do you also get 60-70% battery useage by screen?
Install BetterBatteryStats, or similar, and check if the cpu enter in sleep mode when the screen is off.

Well the software issue might be resolved if your phone is rooted.
try charging yur battery to a full 100%, now go to the file "/data/system/batterystats.bin" and delete it. Unplug your charger and use your phone without restarting of powering it off. Let the battery level reach under 10%. Now charge your phone again (IN ONE GO). Do not unplug until it is again at a 100%.
If yu are not able to complete a full charging cycle, repeat from start.. Don't worry, nothing would get hurt.

Thank you, will try !
I've had my US factory unlocked phone for 2 months and battery life up until now has been stellar. Now, sometime since the December Nougat security update the phone has very rarely been entering deep sleep and the standby battery life has taken a huge hit. Any idea what could be causing these wakelocks? The problem is that they persist even after a factory reset and in completely stock configuration.
This screenshot is only of a couple minutes, but over the course of an entire day, these 2 wakelocks (NETLINK and HVDCPD_WL) combined keep the phone awake about 80-90% of the time when the screen is off.
EDIT: I should mention that the bootloader has never been unlocked, no custom software, firmware or rooting.
I've also just realized that Quick Charge is no longer working - either with the included wall charger + cable or with an Aukey QC3.0 charger. Multiple factory resets have not solved the wakelock issue, so I think it may be a hardware problem. Going to try to warranty it.
These wakelocks ended up disappearing after I flashed Maximus HD and ElementalX. Now, starting yesterday - about a month since they stopped and with no changes made to the phone - they're back and causing massive battery drain.
Anyone else seen these? I figure it must be some kind of weird hardware bug... But so far no amount of reboot / wipe is fixing it.
Any Solution

Hi!
I've been running Lineage OS for about a week now and I'm experiencing poor battery life. I get around 2 hours of screen-on-time and I'm not doing anything demanding other than browsing and social networking and I have the settings on Efficient in the power menu. I feel like stock was a good 50% better on battery life than LOS.
I also noticed that LineageOS System, Android OS and the Phone Idle processes eat up around 30% of the battery.
I didn't install any battery draining apps and I'm running the latest version of everything.
I tried reseting app preferences but it didn't help.
I also want to note that standby time is amazing. If I don't use the device the battery level stays the same while it's sleeping. When I wake it, it loses 2-3% immediately though. It seems that it only loses battery quickly when the screen is on.
Can someone please help? Is this normal battery life on LOS?

if you want more battery life you can use Greenify or something like that. It is stopping the background apps. This is a alternative way. Hope you find your solution

Ah ok have a good career w/ android.. bye
Hey.
I'm using the latest LineageOS same as you, on my LG G2 D802 32GB and having the same issue as you. If I leave my phone on table for a night, it usually drains 1 or 2%, but if I start using facebook or facebook messenger, or just browsing the system settigs, or just ANYTHING, the battery percentage suddenly starts to count down, like 1% every minute or so.
So i've tried stock LineageOS kernel and Lambda kernel aswell (most advanced, latest kernel for G2 atm), rooting and using Greenify, turning everything down to minimal, underclocking GPU and CPU frequencies, changing govenors, battery saving modes on, screenbrightness to minimal without adaptive, everything syncing off, bluetooth, gps, and wifi is usually off, but nothing really helped and it's been buggering me for a week. Compared to the Stock 4.4.2 or 5.0.2, the battery is half as good. Also, I've been reading posts and I've noticed that not everybody have this issue, because some people experience really good battery - or they just say that -, on the same phone modell. I've been thinking about reverting back to stock because of that, but I havent given custom roms like (crDroid or AICP, I'm torn between those two) a shot, but that not relevant to you because G3.
If I find a solution I'll let you know.
LineageOS doesn't have any battery draining bugs for me currently. Have you installed a custom kernel?
G3 D855 user here. Can confirm the same issue, with all nightlies I have used so far. Standby is OK, but it still drains faster than stock. When I use the phone though, that's when it begins to go down waaay too fast. One percent per minute or two tops, certainly at least 2x faster rate. Tried to solve it in many different ways, so far to no avail. Asked some people with D855 and lineage too and they had no issue. It's a mystery to me (btw I bought a new battery just recently)
Second that, same D855 with latest baseband 21C, i encounter same bizarre battery drain..

I'm glad I'm not alone then!
Same problem as everyone else.
Overnight lose only 1% per hour but using the phone it drains extremely quickly.
Look at this crazy battery history:
I've never had this issue on my other devices running CyanogenMod in the past.
Has anyone tracked this issue down to something in particular?
Phew, its not just me. Stock LOS nightlies, pick any... same issue as described by everyone above.
D855/32Gb etc and can not shake it. Wakelocks are all good, as meant to be, just screen on seems to destroy the battery. Have screen on adaptive brightness with around 50% brightness on slider in the first place.
Something is not quite right. Love every other aspect of LOS apart from the battery drainage.
I've got the issue too. I don'y know why but it starts to drain the battery quite fast during the usage of the phone. Any help will be appreciated.
I don't see an open bug unless anyone else has seen one:
https://jira.lineageos.org/browse/BUGBASH-167?jql=text ~ "G3"
https://jira.lineageos.org/browse/BUGBASH-17?jql=text ~ "D855"
There's also this bug:
https://jira.lineageos.org/browse/BUGBASH-364?jql=text ~ "battery"
which is similar to what happens to me, i.e. get to 30% and then suddenly shutdown.
I think this is the bug:
https://jira.lineageos.org/browse/REGRESSION-372
Clear caches!
I was having this issue, with Lineage OS as well as some others i tried based off CM. I would get better than stock battery life for a few weeks, then suddenly the battery would start draining in a few hours.
Booting to recovery and clearing all caches fixed this issue for me.

This is a hardware issue with the battery, not a software one. You need to replace your battery with an official one from a reputable source (careful, there are quite a lot of fakes around, so don't be tempted by saving a dollar).

I had already tried this but no luck.
Could you please check your battery stats?
Does the percentage used equal the total of the individual apps?
In my case, it never does, e.g. 15% usage but only 3% used by apps.

Same for me - the numbers never add up. When this occours, I can watch the battery go from fully charged to 30% in an hour or two, but the battery usage meter doesn't show anything like that kind of usage.
I'd post a screenshot, but I've just taken my phone off charge and have no data as yet. I'll post one tonight - but since clearing the caches, mine is behaving at the moment, although I'm not getting the same all-day battery I was 6 weeks ago.
Same here
Also experiencing this issue on my 6P. Lineage OS system consumes the largest portion of my battery and I usually only get 1hr 50 minutes max of screen time. The phone also seems to die at minimum of 24 percent. Just shuts off. I no longer think this is a hardware issue either as other people seem to be experiencing this. (On a somewhat unrelated note, I also can't flash SuperSU in TWRP without it going into a LOS bootloop)
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?

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. :\

What you said, is nosense for me. Some custom batteries are better than the original. You jsut must be lucky to pick the right one.
