Im getting some weird battery stuff, as well as the Android OS drain. If I restart my phone, once in a while It drops like 20-30%. i'll go from 46% to like 18%. I see the threads about slow draining, but mine seems to happen instantly sometimes (3 different times so far in a week), anyone have solutions? Got it from someone on ebay, can I still/should I RMA?
Someone posted a kernel fix in the international GSII forum, so we're either waiting for that to get ported over here or wait for samsung to release a fix. I have that same bug too. What percent r u getting on the Android OS? Mine is usually in the 60's.
Yeah I saw that thread, and I saw the 2 things causing it. Waiting for that fix I guess, hopefully it solves the big battery drops as well as the small draining. Mines pretty high, 30-50% I believe, and then cell reception takes 10-20% with LOS
That's alot better than mine. Although, I don't have that LOS problem. I'm running stock atm. Are u on a custom rom?
Running Starburst 1.5, stock was better for no LOS. But I like the customization on Starburst. Hopefully by the end of this week the kernel we be ported over.
Most likely a problem with the battery level algo and not an actual battery charge drop. It's probably showing the correct value after the reboot.
Using battery spy I was using like 12%-15% per hour, not even doing anything. Saw online that formating the SD card might help, just did, and now im using .8% per hour. The hell, something was scanning the SD card or something. Much better now, hopefully itll last 10-20 hours instead of 6 hours.
edit: so it went back up again. At .8% it will last 2 days+, but since the events keep taking the CPU, its draining it. I got it down to 4-8% by taking the SD card out. At least it will last a little longer. Cant wait for the fix, this baby will last days after.
Damn that sucks. I just formatted my card too cuz I was running out of options. Keep us updated tho.
so I think media scanner is draining, I downloaded rescan media root from android market and before I was draining at 12% per hour, but when I disable it with the app, it goes down to 5-6%. Anyone else try? Maybe thats something thats draining.
Oh btw have u tried turning off wifi? It only drained 6% after being off the charger for 9 hours. I havent touched the phone during that time span tho. Android os still in the 50s btw.

These are my overnight stats when I was sleeping. It's usually worse when wifi is on.

this is almost definitely correct. battery doesn't drop 15-20% because of reboot...the reading is wrong. Battery drivers have been bad on a few of the latest android phones. Just look at when your phone stays at 99% for the first 3 hrs of use each day...what, does it just get really inefficient in the afternoon because of food coma from lunch?

Trying now, seems to be charging faster too. I was mainly on wifi because cell standby was really high, keep getting LOS. But maybe I wont with wifi off now, and i'll see how battery does. ill keep you updated.
Still bad. Can only wait for the patches/fixes. 8 hours doing nothing almost. Sigh.
edit: sent to the galaxy support on twitter, see how that goes.

Hey man, I got one more tweak for u to try. I just rooted my phone w/ the latest zenomax kernel and Starburst 1.5. Download setcpu and create a profile for "screen off". Set it to 200-500mhz on demand. In theory, this should prevent 100% cpu utilization while the screen is off. I'm testing this myself atm, so I can't give u my battery stats yet.

Think I have the v3 version and 1.5 as well. I have setcpu set to 200-400 powersave. ive tried others and same. Suspend and events/0 keeping eating at the CPU. Thanks for the suggestions though.
figured i'd chime in here. i've had days where the battery was fine and days where the battery was absolute trash. it's happened on stock, and it's happened on root. but it almost always seems to coincide with LOS. the first picture is one of several instances where i've had pretty fast drain followed up by an instant dump in charge under normal use. it's strange how after the drop, it slowly works back up then levels off and drains normally. the 2nd pic is from today. i left my phone at home on accident when i went off to work, and when i returned, i had LOS and this battery stat. you can tell where i lost signal . the last pic is from yesterday while i had the phone at work all day and light use; a nice consistent drain.
FU battery drops and FML
Ok so i read all the posts in this thread and i understand theres a issue that effects the phone from even knowing what the battery % is. i had to post these though. i was at 47% then rebooted my phone. phone boots up and yehhh! woop woop 8% now mind you if you look at the graph it shows a nice constant cerve downward but steady because i was using my phone the entire time. now after the restart/batery drop of 40% i kept using the phone constantly but its funny how it took me over a hour of screen on to go from 8% to 5% !!!!! i bet to get from 5% to 1% it will take 2 more hours for sure. you can see the graph start to flatten out like its a super battery after the 40% drop because it didnt really drop to 8% !!! normally i wouldnt care since my phone battery last just as long, it just goes down really slow from 8%-1% but at 5% it auto dims screen and wont let me use my camera for the next 2-3 hours while i knock off the remaining "4%" of battery left. fml
Get Starburst v1.6. He removed DRM processes which should lower Android OS usage and thus battery draining. Plus with the LoStKernel, I haven't had any issues with losing signal since.
Also, use Titanium backup to remove running services that you don't need. I got rid of the stock email client, digital clock, media/social hub if you don't use those. They don't take up a lot of ram, but every little bit helps.
My battery life has improved after battery calibration. I suggest you calibrate if you didn't already so your battery usage graph may be more accurate. Hope this helps.
Thanks for the tips! I was wondering how you would calibrate the battery. Is it the same as wiping battery stats from CWM?
I feel like I make a thread for each phone I go through. First Blackberries, then Droid X, now Galaxy Nexus.
I am getting pretty horrible battery drain that is definitely worse than others' Nexuses. I have gone to the extended battery now for a few days, yet in the morning, when I unplug from charger (says 98% but charged?), with brightness only a quarter of the way up from lowest, I can literally watch the percentage (battery number mod in corner) drop one-by-one each minute or a few...So if I am actually using the phone, you can imagine it drops pretty fast. Yesterday, with very very moderate use the phone was still dead within 5-6 hours. It was at the mid-80s within an hour or more. Again, with moderate use.
It is stomach-dropping watching the percentage number just go down and down. Yet my friend's Gnex using the extended battery his first day did not hit 85% yesterday until 5+ hours later. The battery stats page on mine shows nothing with high numbers except Screen and Android OS, so I assume no apps are draining it. I am rooted with unlocked BL, on bigxie's deodexed ROM with softkeys mod, battery percentage mod, and power menu mod. I have 100-something apps and many widgets but no battery draining/updating ones. Others with the same ROM report fine battery.
I believe after using the ext. battery for a couple days, it should be "conditioned" if needed at all, yet I see no improvement.
I'm getting very angry watching this drop.. For example, 40 minutes off the charger with almost NO use except for turning the screen on here and there, I am at 94% battery with Screen at 46%, Android OS at 34%, Phone Idle 11%, Cell Standby 9%, and Android System 2%.
And then 1 hr 20 min in, at 88% battery with 55% Screen, 27% Android OS, 6% Phone Idle, 6% Cell Standby.
This doesn't sound normal right? Keep in mind, those numbers are with almost no phone use..very minimal settings menus visited and one update from Market.
Jesus, literally almost every time or two I turn the screen on just to check these numbers, I see the damn battery percentage drop a number. Not even using the phone how/as much as I normally would be. This is infuriating. Luckily, it doesn't seem to drain much with the screen off.
Quit checking and wait til the bug is fixed and blood pressure stabilizes?
Crazy world, ay?
Update to 4.0.2 or 4.0.3 with an improved kernel = success.
Use the phone for 1-2 weeks to stablize battery life - mine is better now than it was when I began using it. But the kernel/rom makes a big difference.
Thanks. Any suggestions on with combo to use now? 4.0.3 preferrably I guess.
Then why does my friend on totally stock 4.0.2, non-rooted have that great battery life from the first day using the extended battery?? I'm pretty much basing mine off of his and other's who are getting ridiculously long life. I never understood how it varies SO much. We should all have the same relative to usage.

No. Because no two phones are set up the same. Too many variables to say relatively same usage. For instance, when i go to bed i get 2-3 hours standby per percentage point. Not everybody is going to get that.

Maybe, but the fact that I have no other visible outstanding draining factors, and I get no 4G at home and therefore have it set to CDMA only...I should not be seeing 1% drops almost every time I turn the screen on for more than 30 seconds. Especially with an extended battery.
God forbid I want to use GPS or 4G.

Wow, really? At first glance in all sub-forums I saw about two, if that. I have a legitimate concern, especially when my friend is getting about 4 times better life. Thanks for your help though in the device forum where this 'doesn't belong'.
..And over the course of only a few minutes of the screen being on maybe twice and sending one email, I saw it go from low 82-83 down to 77. ****ing awesome.

You probably have a misbehaving app. Download better battery stats from the android apps and games section here at xda and let it run for a day or so and see what processes are being used the most and what your wakelocks are, etc.
Also, find a 4.0.3 rom with a kernel that can be undervolted and try that out.

Thank you, downloading now and will check it out.
I'll admit I'm using the GSM version so my experiences may not apply but for the first few days my battery life was utter crap.
Its been MUCH improved over the last few days, I dont have the wakelock issue and with the screen off the battery drain is literally only about 3% per hour, and thats with background data on.
YES, the screen DOES use a lot of battery, it isnt really avoidable and is somewhat expected with a 720p 4.6 inch super AMOLED screen.
The one thing I can recommend doing is finding a modded kernel and undervolting that CPU - It seems they've been really rather generous providing power to the thing, I've been able to take off at least 100-150mv across the board.

This - My battery on the stock battery on GSM sucked first few days, and I was really concerned I made a poor purchase. But with the screen on probably 5 or 6 hours of my work day it lives through the day and just enough to get home after that. I can charge it at work too, which I usually do. On my day off it survived 18 hours and still had ~20% battery life left on 4.0.3 AOKP/Francisco.Franco Kernel
From my experience, the battery life isn't bad. I did install the "extended" battery as soon as I bought the phone but is isn't much bigger than the stock battery. I am on stock rooted 4.02. With LTE off I use about 2% per hour in standby. With LTE on it is almost double that (3-4%/hour). I have several widgets running and gps enabled. (wifi when available) I can easily get a 16-18 hour day and have 50% remaining when I go to bed unles I sit around gaming for a couple hours.
I may try a new ROM tonight but I expect it will probably make things worse.
Im running a bone stock setup and im getting 12 -14 hours a day... normally I read posts like the one skiddingus posted and wonder why I never can achieve those readings so i feel your confusion . I do have 4g on and gps off screen is about 1/4 of the way up brightness wise
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
I've looked all around for any thread similar to this - couldn't find it.
Long story short. I rooted my phone and installed CM11 (Sept 14). My battery used to last around 30 hours. Now I'm lucky to get 8 or 9. Without any use, I lose around 40% during the night (7 or 8 hours). I used to lose 7 or 8%.
Is anyone having the same issue?
Go to the battery tab in settings and find out what is using the most energy. You can also use greenify to monitor usage.
Or try diff kernel..
what are your governor settings, and clock settings?
You can use Better Battery Stats to track down what is causing the drain.

Clock is stock, governor settings are at "interactive". I got Better Batery Stats. "Android OS" is draining my system. There were a couple of modules mentioned. I was expecting a rogue app was eating up all processor cycles.
I downloaded the Deep Sleep widget. My phone had a 35% deep sleep time.
I'm pretty sure it's doing something all the time that is draining the battery...
So I installed DS Battery Saver Pro. All I can say is WOW. Battery drain went from 7% (on stock Galaxy Note 3) to 40% on CM11 to...
0% overnight / 97% Deep Sleep
That's right. 0%!!! I can't believe it! Battery life is so much better and performance is basically the same.
I guess something was keeping the phone awake with CM11, and DS Battery Saver Pro fixed it!

Not that this will help you, but I had the same issue. Normal usage would drain before the day was over...went to Tweaked 3.55 and problem went away, which sucks because I LOVE CM11 minus the camera...for some reason I think the camera is always better with stock based roms.
DS Battery Saver Pro only did so much. With normal usage my phone simply won't last a whole day. CM11 is killing it. I have nothing else installed...
Found it!
So, I found what was eating up the battery. The battery stats didn't help. DS only saved some of the battery at night. The phone was simply consuming obscene amounts of energy while on and every indicator seemed normal.
It was ART!
I went back to stock Touchwiz and hated my phone so much I was this close to selling it and getting a OnePlus. But I reinstalled CM11 and decided to add apps one by one to find out what was going on. Everything was fine and yesterday I finally enabled ART in the end. The phone wasn't any faster, but it went from spending 3-4% battery at night to 45%. And during the day, it dropped 1% every 2 of 3 minutes with light use.
So, there it is. Blame ART and never enable it on CM11 if you have battery issues.

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).

This sounds like some app you're installing on your phone.

I'd generally think that, but I haven't installed any apps for weeks!

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)
