Battery drain on lg g2 - G2 Q&A, Help & Troubleshooting

Hey,guys! I'm having some problems with my g2 lately. For two weeks now I have been having severe battery drain. When I open the battery menu it says that android system is using 25%,sometimes drops to 22%,sometimes goes up to 30%. The screen usage varies. I don't know what to do. I can barely get 3 hours screen time,most of the time i get 2 hours. Last night I left my phone at 12AM and I had 40% battery. Haven't been using it till I woke up and when I woke up the battery was dropped at 16%. That is just extreme! Any advice?

Turn off locations.
Long press power off and reboot to safe mode for a couple of hours. If bad battery continues just perform factory or hard reset and it will be fine. If battery life is good in safe mode then some app is eating your juice (no pun intended).

Hope you wiped cache .
Install clean master feom plan and let it scan. Follow suggestion promted also install grenify app (requires root) and hibenate the app which runs constantly. For this check app running section in settings. A
You can also have titanium backup to feeeze apps which you do not use and see them running to save some juice

Notice battery issue recently.

So im at a convention thisweekend and its been a while since I flash my rom to 3.2 freshbaked. This weekend I notice straight from 100% I was burning through most of it in 6-7 hour with out alot of usage. I took my phone out at 11:30 today and its only 4 and im already down to 36%. My battery usage shows 36% from system 22 from cell standby with 0 signal lost and 21 idle. Ill flash an updated rom when u get back.

flashed new 3.3.0 fresh and after a full charge i've left it idle for 2 hours and i've already drained 20% of the battery. That roughly 10 hours of doing nothing and my phones dead.
It could be some app you are using/installed.
I recently flashed Fresh and expierenced the same situation . My Android system was always the highest on the list . I removed apps and stripped it down , I wiped Dalvik and Cache you name it and the phone could sit idle and the Android system would be as much as cellstand by if not higher . I eventually just went back to stock Froyo with root . Android system now sits lower than cell stand by and phone idle
I'm using the newest fresh Rom with kings 9 kernel and set CPU. I never been a heavy user but I'm sitting at 19hrs and 43% I took it off the charger around 3pm Saturday and have not charged it since.

fresh 3.3, and netarchy's 4.1.9.1 fresh comp kernel, run your battery down to 3%, once there, boot into recovery, wipe your battery stats, and then reboot, once you reboot you may only get as far as the lockscreen before it shuts off, then either swap in a spare fully charged battery, or fully charge your battery with the phone turned off.
This is insane I'm currently Losing 1. 5. % a minute. Took it off 8 minutes ago and its down to 86 with 70% system usage

What is your signal like in the building? I had a similar issue when I couldn't get a good signal. The phone would last four hours just sitting on my hip.

Unique Battery problem

Sorry to start another thread on battery issues but I was unable to find a scenario like mine.
Hey everybody, Im new to the android scene, just got my vibrant less than a month ago. Before that I had an Iphone 3g. So far I like the phone but the battery life is horrible. When I surf the internet on wifi or 3g I noticed that I use like 3-5% in a matter of 5 mins. Is this normal? I consider myself to be a light-moderate user and have been getting and average of 12 hours or so on my vibrant. Also if it makes any difference when my phone is idle or being used my temperature runs around the high 80's low 90's but when being charged it drops to the low 80's or high 70's. What is going on? How can I get more 20 hours on my phone? With the iphone I used to get an easy 15 hours and still have like 40-50% remaining.

When I first got the vibrant, it had pretty bad battery life, I would lose like 25% while sleeping 8-10 hrs. So light usage would be like a day. Slowly I started to get longer battery life (2 days on light usage). Recently I could get up to like 3.5 days on real light usage. After updating to JI6, max I can get now is like 3 days. I didn't really do much and I tripled my battery life by just giving it time.
Thanks burntrat I guess ill be patient. And I must mention that I am running stock.i was just worried because my battery temperature gets colder when charging and warmer when idle or running.

Hey burntrat or anybody, has your battery ever acted sort of schizophrenic on you? I mean one day I leave it on standby and its drains like 1% in 7-10 hours another day I leave it on standby and it drains 18% in about 4 hours. Whats going on?

My battery has been draining inconsistently lately. It drains faster in the 50-100% level. Under 50%, it feels like it drains slower while doing the same stuff.

if your phone is draining a lot during standby or sleeping. There may be a rogue app out there or an app that didnt shut down properly. (I guess that would mean a rogue app)

@aamir123 and burntrat: maybe you guys need to calibrate your battery? Also the stock rom usually has a lot of bloatware running in the background. Flashing a custom rom oughta do the trick.

How do you recalibrate the battery?
Sent from my SGH-T959 using XDA App
Try this. Download the system panel app from the market. You can set it to monitor your system and it will chart what applications are running and how much they are using the cpu. If you find you have some unnecessary bloatware running in the background download titanium backup and freeze those apps.

There are a lot of different ways mentioned in different forums. Try this:
Let your battery drain all the way to the point when it turns off by itself.
Charge it while its off until its full.
Unplug it, turn the phone on, then plug it in again.
After it reaches 100, unplug the charger and turn your phone off.
Once off, plug it in and let the charging complete.
Once complete, unplug it and turn the phone on. When everything has loaded, turn the phone off (note: no charging involved in this step.)
After it turns off, charge it one last time until 100%. After this, go into recovery and clear battery info (or cache, I forget). There you go
Oh, and its better if you don't download too many apps that monitor battery usage, cpu etc. cuz they will contribute to the battery consumption.

It isn't a good idea to let your battery drain all the way to zero since it is lithium ion. I think skipping that part and just charging it when it's on to full, then off to full, then on to full, then off to full and then wiping battery stats would suffice. Also you need to have clockwork recovery to wipe battery stats.

When the phone turns off by itself, the battery still has some juice left in it to prevent it from losing the ability to charge, if that's what you meant by not a good idea cuz its lithium ion. If thats not what you meant, then please explain why.

Agreed. In my case, I barely lasted 12 hours on moderate use with any of the JI6 2.1 ROMS (Eugene's, Bionix, Fusion, etc). I think after I updated to 2.2, all of the ROMS have been giving me 18+ hours on moderate-heavy use no matter what modem or kernel I use.
So where is the "unique" problem?

[Q] Strange battery issues

I have CM7.1 on my MT4G. Over the past week or so, my battery has been dying after 2-3 minutes of use. I'll get a full charge, take it off the charger, use any app(Angry Birds, Gtalk, text messaging...) and the phone will shut itself off after just a couple minutes of use. When I turn it back on, it says 2%-3%. It then shuts itself off again, I plug it in and turn it on...says anything from 3% to 90%.
I've always ran the battery down and charged to full. Is my battery kaput? Is there a way to fix this?

Most likely.. take out the battery and inspect for leaks(might be very small discharge you might not see it clearly leak can and will damage your phone)..let it die completely, and let it stay off, charge it till the green light comes on, reboot into recovery, clear battery stats, reboot and see how long it last, also change your brightness, and other settings that might be consuming battery use..if none of these helps.. just buy another battery.
Sounds like your battery is screwed. Just buy a oem battery or get a mugen power 1650mAh

My issues aren't quite that bad, but after I upgraded to CM7.1 from 7.0, by battery has been terrible. 15-20m of phone calls over BT takes ~20% of the battery. 15m on Angry Birds chewed up ~40% of the battery. I downloaded the latest nightly (252) and will see what happens.
Try a dif battery and see if it does the same thing. So you can rule things out

Mines also been horrible since I went from CM 7.0 to CM 7.1. Not sure whats up but it dies in like 6 hours on standby. the battery use app shows that most of the battery usage is by "Cell Standby". So effectively, doing 'nothing' is eating up the battery?
~Phil
I guess I'm not having the problem you guys are having with battery drain. Granted I didnt use my phone that heavily, but still sitting at 60% after 10 hours. But if your battery is dead after 3 minutes something is seriously wrong, I agree and try a new battery.

You need to calibrate the battery after changing ROM's. Download a battery calibrator from the market. (Don't pay for one. There are like 10 free ones)
Charge the phone fully overnight. Calibrate it in the morning.
Give it a few days to gather new battery data, and then enjoy getting a full day's use from the phone.
Update
So, it's gonna have to be the battery. Recalibrated, no good. Tried a few different ROMs from CM7 nightlies to MIUI, no good.
Waiting for the new battery to get here to be sure.
Thanks for all of the help and advice!
same problem here
hello there, i got 2 mytouch 4g both running the same rom (virtuous unity 2.39) one of them has eaten 2 batteries that i bought thinking that the batteries were somehow broken or damaged... i came across this thread, read the reply recomending battery calibrator when i reached for my phone (that i left sitting on my drawer waiting for a new batt AGAIN) to give it a try and to my surprise it was still on and i has been on for 2 days 11hours and the fricking battery was at 97% before that it started to turn off-discharge so i put the thing on airplane mode and there it was till now... dunno why or what but i think it has something to do with the radio/network... hope we find a cure for this
I've been having this same issue, and I was wondering if replacing the battery fixed the issue? Thanks.

Battery problem

Hi folks....m using galaxy note...it's not rooted...the battery doesn't last long enough as it is claimed... is it something wrong with my phone or is this what they mean by long battery life... i text alot and during texting and playing gamea my phone gets warmed up and the battery lasts less than 3hours if i continue texting...my kernel version is [email protected]#2.....please help....

It sound like you have a faulty battery if it only lasts three hours, I think you would have to be gaming to flatten a good battery in that time.
John.
Mine is the same. If I'm browsing the web, using instagram, Facebook and receiving email my battery will go from full to empt in easily 3 to 4 hours.
Backup, factory reset, reinstall apps from market (try to install only the ones you use a lot at first), restore the data you need. If you're still seeing the same things happening, install a battery logger / system logger. Use this guide to see if there's a rogue app that's causing the trouble: http://forum.xda-developers.com/showthread.php?t=937080
If it's still acting up and you cannot identify any unusual drain, I'd ask for a replacement.
After you get things sorted, you can use apps like Juice Defender from the Market to prolong your battery life even more.
-KJ
thanks guys for the sincere contribution.... i hope your advices help me...
my top battery consuming activities are:
temple run
google play
msging
go launcher
and nothing else
gaming and browsing certainly make the battery drain almost visibly..
things above and beyond the above to try include..
1. reduce screen brightness
2. reduce frequency of or disable background updates by apps
3. no vibrate notifications
4. work more, play less!..lol
the battery life of the Note is great, unless you use it .. a battery monitor will allow you to see the battery drain over time..this will help when you address item #2 above.. if you accept default refresh times, and have lots of social apps your battery can die in 6-7 hrs without even using the Note at all!..

some hints for better battery life
Got mine the other day. First charge battery was fine. Second charge went down 7% in about 5-10 mins. Then it restarted :/ Came back on, down to 88%. Turned the phone off as was frustrating me as it restarted 3 times yesterday. But when I turned it back on I was at 83%?
Hasn't last me the day, it's on charge now. When it pops up telling me to charge it tells me to shut all apps and that using while charging may effect it charging. Is this correct? I didn't think it would have anything to do with it?
3 to the 4 hours continuous use is normal... Only if your phone is standby and then depletes in that time You should be worried. I recommend researching wakelocks in that case.
There are many variables that can atribute to batterylife depletion. Eliminate those first and you will have your answer.
I had best results on stunner version 19. To bad it has the death kernel (leaked ics)

Installed Better Battery Stats and discovered that the CPU was always running.
Factory reset solved it...

[Q] Huge Battery Drain

I dont know what is wrong with my N4 but suddenly it started consuming very much of battery..earlier it used to give me battery run of almost 20+ hours with normal to moderate use but now with similar usages my battery does not even lasts 8-9 hours.
ROM:- Carbon (Nighly 19th September)
Kernal:- Franco (JSS r183 nighly)
Governor:- Interactive
I have installed both BBS & Wakelock detector...but there is no rogue app keeping my N4 awake..
As per my today's analysis
Battery lasted 8 hr 30 mins.
SOT(46min)
Voice Calls:- 8 mins
Awake %- 33% (rest of time deep sleep)
Usages:- Very less use (was at office whole day and phone was sitting idle at my desk)
And i have noticed a strange thing :- it takes very long to charge completely..Earlier it used to get fully charge in 2-3 hours..now its taking almost double of it.
Any ideas people...My N4 is just 5-6 months old..Is there any issue with my Battery..? I can not see back of my phone swollen or nething..
REally appreciate the help
Could be a battery problem but you might want to try simulating a battery pull you can do this by making sure you n4 is powered off and not on the charger then hold the volume up and power together for 60 seconds, reboot and see if theirs any change.
