Last straw was last night. Had 13% battery life left before softball last night and knowing I wouldn't use my phone during the games, but having been burned by my battery before, I shut my phone down before the games. Played softball for two hours then turned my phone on. Booted up long enough to see that I had 0% battery before it shut down again.
What am I doing that's causing this? I get maybe 10 hours out of a Seido 1750mAh battery. I have no apps that do background updates. I keep my display on "dim" most of the day. I go most days without even making or receiving a single phone call!
Ideas? Thanks for any help. This is really frustrating.
Cyanogen Mod 7.0.3
Kernel: 2.6.37.4-cyanogenmod+ [email protected] #27
Baseband: 2.05.00.06.11
Seido 1750 mAh battery
I'm not sure, but there have been claims that Seidio inflates their numbers and their 1750 mah battery isn't actually that much. Has this been something that has been happening gradually? Like your battery life is degrading over time and now it's at an unbearable point?
Try a different Kernel or Baseband. I'm using MIUI w/ incredikernel and get great battery life w/ stock battery. I'm also using 2.15.00.07.28 Baseband. I use SetCPU to set a screen off profile of 245min 245max, havn't noticed any lag while having that set. If you wish to update your radio easily you could download "Inc Bits" from the market. Great app has all of our phone radios, all you need to do is rename it and move to SDcard.
Agree with tcberg2010 here. Try incredikernal with Smartass governor. Check out vipermod. I was having intense battery issues which i posted about a week back. My suggestion would be to get spare parts app and check partial wakelock to see if anything is keeping your phone up. I use maps occasionally and it turns out that it was causing partial wakelock constantly. After disabling a locations and gps i am back to standard battery life. Looking forward to next cyanogenmod update, hope there is a fix...
If your phone died while it was turned off, then I would either have battery tested or get another one it could have an internal problem.
Yeah unless the phone some how got turned on in your pocket (I'm not sure how, but it has happened to me), There should be minute if not no drain on the bat at all. I'm not sure where you can get it tested, but I would certainly be wary about that bat. Do you still have the stock 1300? I'd check to see if it looses charge while the phone is off. Maybe there's a short in the phone.
Thanks for all the suggestions. I'm at about 10.5 hours right now and 7% left with the only thing I've changed being the battery. I went back to my stock battery. Going to try a new radio first, then vipermod.
try the "battery moniter widget" from the market. it keeps perfect tabs on your battery, can tell you the REAL mA of your battery, temp, usage stats, all kinds of stuff. it's really a good app to use to watch your battery...you could also use MIUI, and watch your battery life almost double. it's superior to CM7 in so many ways. and the people that have used both, i think pretty much agree...
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.

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.

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
Hi! I'm using a gt-I9195 with stock 4.2.2 and arco's kernel. I've got this problem: after I get the battery popup warning, this wakelock pops up and keeps clock frequency at 810 mhz the whole time while idle. The battery drops so fast that after a few minutes the phone already shuts down itself. Sometimes I get the first popup warning (at 15%) and no wakelock, but usually after the second popup (5%) the wakelock appears.
I'd like to use even the last 5-15% of charge. This way, I absolutely have to charge the phone before 15% to be sure that battery won't start to drop like crazy.
I found nothing about this wakelock. What the hell is that??
After some days, I can say that it doesn't pop up always at the same time. Sometimes at 15%, sometimes at 7%, sometimes at 3% etc. And sometimes not at all.
However, EVERY TIME it appears, battery starts to drain like CRAZY. It is not a "regular" wakelock. In 2-5 minutes, battery is died. I keep reaching this low battery levels just for testing purposes... I really don't understand this wakelock.

Not that this will help you any, but seeing as no-one else has responded, just thought I'd let you know you're not alone, and also it's not a problem specific to Arco's kernel - I seem to get the same thing on a completely unmodified S4 Mini.
It suffers from the 'battery drain while idle' bug anyway, for which I'm planning to install Arco's kernel soon, but somewhere between 15% and 5% remaining each time the drain really goes nuts. I can't see the CPU speed, but I've an app installed to monitor and log battery drain in % per hour, and it's usually around 3-4%. After the low battery warning, it jumps to 70-80% an hour, and like yours my phone can go from low battery warning to dead within a few minutes, just sitting idle.

Glad I'm not alone. I assume you're on Jelly bean as well since you're talking about Arco's kernel whch is for JB firmwares as far as I know.
Maybe on KK this weird drain has been patched, some reports from KK stock firmware users would be interesting.

Yes, on JB - I thought it might be a battery calibration issue until I saw your post about the CPU (and until trying to calibrate the battery didn't do any good).
Would be nice if KK fixed it, although it'd probably be by chance - since I can't find any mention of the bug online except in your original post, it doesn't look like it's affecting many people, so doubt if Samsung are even aware of it. Still, fingers crossed!
Yeah, searching pm8921_bms_low gives very little results. For what I understand, usually this is a wakelock of 1 second or less that pops up when there's the battery low warning.

Hi again! Just wondering if you have any battery saving apps installed? I had one called Battery Doctor installed, and removed it after installing Arco's kernel as I no longer needed it - since then I've let the battery run down to 2-3% on several occasions without seeing any sudden drain. Previously it always seemed to happen me at 5%, and often before that. It might be worth removing any battery related apps just as a test.

It might be just luck... otherwise I don't know what to think It happened to me as well to reach 2 or 3% with no battery drain at all, but never regularly.
I don't have battery saving apps (last one I've used was green power two years ago), only greenify but shouldn't make a difference. I read from another forum that plenty of people have this issue, a guy sent his phone to samsung for this specific problem and wrote that he will inform us if they'll solve the problem (honestly, I hope it can be solved by swapping the battery or updating the firmware ).

That is strange - I was getting it literally every time at 5% if not before, and I still haven't had the issue once since I last posted, I've kept letting the battery get down to 2-3% each time just to test. Oh well, I'll enjoy it while it lasts! Will let you know if the problem reappears, and will be interesting to hear if this other guy gets a solution from Samsung.
I tried to let discharge it again and the drain appeared somewhere between 7 and 6%. I definitely have the issue but I've learned simply to plug it at 20% or more, it is better for the battery too.
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

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..

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 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.

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)
