Horrible battery life

Hi,
as I got the phone I already had bad battery life, so I made a factory reset, maybe it helps. It didn't, 1 hour of playing(not even 3d game) ate 40% of my battery, on 2g network and 40% display brightness.
I decided to put on the EURO open(jun 25) and root the phone. I uninstalled a couple of system apps(car home, unused apps, etc), and also put on minfreemanager on agressive settings(to kill background apps consuming battery).
It helped absolutely nothing. I disconnected the phone from the charger in the morning around 6am, and by now with approx 20 minutes of gaming, downloading it's only 75% left.
I also discharged my battery 2 times to 0%, and turned on repeatedly to kill the battery, and once recharged while it was on, once recharged while it was off. Helped also nothing.
some info if needed:
baseband: 1035.21_20110725
kernel: 2.6.32.9
build: FRG83G
LGE ver: LGP990-V10d
Please help, it would be such a good phone without this battery issue ((((((((

Install juicedefender

I installed it in the stock one, but it didn't help.
As I see I have problem when the phone is active, and I do something with it.
When my phone is sleeping it seems okay tho.
I played stupid zombies for 10 minutes just now, and it went down from 70% to 65%. This means every hour battery dies 30% which is actually 10% better then yesterday with the stock rom before this open EURO. It still is pathetic, that you can only play 3.3 hours and your battery is dead
My SGS was able to hold on at least until 5 hours with heavy usage.

I don't know guys my phone can last for 3 days only using for phone calls. Watching 2 hours of youtube can last 2 days.
Maybe because i don't use any Internet via mobile network.
I don't use task killers. After reading this http://lifehacker.com/5650894/andro...ed-what-they-do-and-why-you-shouldnt-use-them
I always charge the phone when the battery goes to 0%.
Autobrightness is always on.
Always use 2G networks and Data is disabled.
Useing Modaco Fear edition 12.6.
with baseband 622.
with TW Launcher.
5 Homescreens full of widgets.
and useing Watchdog Task Manager for monitoring what app uses cpu most.
So im very happy with my phone with heavy use i can still manage 24 Hours (Browsing, playing, Youtube). And maybe 6-7 hours of max usage.

I had about 5 hours of battery life on idle when I first got the phone brand new. I'm getting about 40 hours on idle now with Fear 12.6. I'm still testing whether underclocking cpu while idle will improve battery performance. But i dont use any app-killer and do NOT use JuiceDefender, it doesnt work well with this phone. Havent updated baseband, using stock _20110405, make sure you have matching RIL to baseband, so dont simply update baseband.

Try cronos Tom, it has been optimized battery driver, I've just bought brand new 2x 2 days back, my battery was lasting hardly whole day with 2-3 hour wifi usage then i read somewhere its a known issue with with 2x, not same like ur case, then I try various roms the only rom that gave me longest battery life on my phone is cronies mod, try it

Horrendous battery loss!!!! :(

ok....am totally depressed with the awful battery loss that i am left speechless!!!...
here's what i did
3 and a half hours on standby....45 minutes of music playback on headphone in LOW volume.
1/2 hour of angry birds @ full brightness.
15 minutes of surfing @3g with full brightness.
rest the phone was idle.
tried battery calibration, wiped battery stats, using task manager regularly. nothing helps.

v20? mine draining batt as well..

Im on temasek P20-32 and using Wi-Fi more than usually and battery is droping down every minute. Ill try kernel nova 11c and hope that this is my last chance.

cyanogen sucks for battery, it will drain like hell with wifi on

Mine also drain battert very fast! even in my sleep time. but the strange thing is even battery reached to zero, it doesn't turn off! i think it has a problem with battery level indicator.
Ps. now i'm using V20N kdz. considering about turning back to V10E Thai but regreting the smoothness of gingerbread

same here with V20N when i sleep i put`it in plain mode with 90% when i wake up the battery was 0% and now i`m back to V10F in battery monitor say`s at a certain hour/min the battery from 70% was gone to 0% and about activities that drain nothing strange , seems normal like battery monitor say`s

I have some tips for the battery:
- use your phone till it drops to 1%
- reboot you phone
- charge it till 100% (don't use your phone while it's charging)
- then turn it off
Believe me,it'll last for a week

Maybe you just have ****ty ( malfunctioned) batteries ? Buy new ones and test.
I am NOT sarcastic.

OP where are you? I am using CM7 #39 stock kernel, with no simcard, dropped 6% in 8.5 hours idle. But if there's data connection available and sync turned on, you only need 10-15 minutes to drop 6% (idle).
We need a good kernel, redy2006 told me if anyone could port Nova v3 kernel into stock GB/CM7 all in one it would be great.
Like universal Siyah kernel i am using right now on my SGS2 (MiUI ICS), very great sleep setup and reasonable wakeup battery use. I can managed up to a day much better than my OB (CM7#39-stock) that can only managed up to 10 hours with the same apps and behaviour.

weird and inconsistent battery!!!!
ok...i installed zeus1 over again, wiped batt stat and installed the echelon theme.
sersly, dats wat i did!!!....nw screen set @20% br8ness, played for 20 minutes, 15/20 mins f music playback & a good backup
now i hv 94% left!!!

[Q] ICS is not going into deep sleep after 6 hours Screen shots attached

After switching into flight mode - reboot (took out the battery ) - switch back from flight mode. Note was going into deep sleep.
But whenever i used the phone or played little game, battery was depleting around 1% in 5 min.
Now suddenly after 6 hours of use again ICS is not going into deep sleep.
I have attached screen shots of cpuspy and betterbatterystats.
Please let me know if anybody can find something in screenshots.
ICS is really getting irritating. I am always looking cpuspy and battery stats from past couple of days instead of enjoying my Note.
Also please let me know how to go back to GB os. I dont think ics having any major changes against GB from a normal user perspective. GB was lot stable.
Note: Never rooted.

If now it goes to 200 MHz and not to deep sleep when screen is off, some app must be keeping the phone awake. I'm running LPY with 37 apps installed, and used a few of them for days. Phone keeps going into deep sleep when unplugged and screen is off:
Speed is limited to 1200 MHz by power saver setting
200 MHz time is mostly while charging

I'm having the same problem. Some days it goes into deepsleep other days it doesn't. The day it doesn't, my battery drains 50% faster.

try task killer app and reduce ur screen light minimum possible and switch off wifi,bluetooth,gps wen not in use...
else every thing fail out try rooting with custom rom like KingDroid ICS ROM v2.0 its osum...!!! all d best dude...!!!

I also have this problem. I don't use my phone very often, so the screen is not draining as much power, but sometimes I get the phone to use 5mah in battery widget, but most of the time it just hovers 35mah or above.
I would really like to be able to get the one digit number when the phone is idle. I am still on Gingerbread but I would like to know if there is a way to solve the high Android battery usage?
I keep Wifi/3g on 100% of the time, as I did on my previous device running Android (HD2) and when the screen was off the device would only consume 4-5mah of battery.

[Q] ParanoidAndroid v.03 huge battery drain

Hey guys, i just wanted to know if anyone is getting this issue. After installing paranoid android V.03 im having this huge battery drain. Almost 10% battery loss every 40 minutes even with Mobile Data and WiFi off. I should say i've flashed this rom over a stock gb. There is no modifications and the kernel used is the same that comes with that rom.

look for BetterBatteryStats and CPU Spy, download it. Check in CPU spy if ur phone is going into deep sleep, If not, put it in airplane mode, reboot and turn airplane mode off, if still not going in Deep Sleep, open BetterBatteryStats check the wakelocks and come back here.

First day on v0.3 I had the same problem. But it was really interesting when I figured out why the battery drain was so fast.
Look at your battery status if there is any drops like 3-5% which was happened immediately in a second. If yes your system is rebooting sometimes and that makes your battery drained. I had 1 or 2 reboots every hour on the first day.
If you didnt wipe dalvik cache and wipe cache after flashing the update may be that is the problem.

i did wipe the device. I have not notice any reboots . I'll fully charge it and check the battery life again. I've notice a fast battery drain even when i'm using it to text only. Like it's 80% one moment and when i look back at it it's like 78% Out of nowhere ( and as i said no data or WiFi).
Edit: almost forgot to mention. Just checked the cpu spy app and it does go into deep sleep(it shows an 8hour record in that state).

If you flash a rom with less than full battery it will take a few days/restarts/charging cycles for the battery stats to reconfigure correctly. This is the case with all roms, stock or otherwise.
If it persists after that, better battery stats should help identify what program is swallowing all the juice.
PS. I'm on same rom and kernel and have excellent battery life so it should resolve itself after a couple of charges.
Sent from my Paranoid Android GT-N7000. It doesn't get much better than this!

Well.. i've been using it as always, and still feeling like it's going down too fast. When i flashed the rom , i did it with full battery. Anyways, i'll keep using it for a few days more and see if it changes. i've installed betterbattery stats and CPUspy as you guys recommended, so i'll keep an eye on it. Thanks for the replies, i'll let you know guys any changes :good:

ihave this problem with this rom battery drain
WTF ??!!!

[Q] Kernel = Battery Drain??

Noob question. Does the kernel have anything to do with battery life? Me and my wife both have a note 3. Mine is rooted hers isn't (4.4.2). Her battery life is great but Im not having any luck at all. If I charge my phone over night i wake up the next morning with 92% AND ITS STILL PLUGGED IN lol. Its like it stopped charging in the middle of charging. I would then have to unplug it and plug it back in for it to charge completely. through out the day I will get a full day but around 10 pm I would be at 30% or less with moderate use. Now thats ok but for this phone I should at least be at 50% with moderate use right? My kernel is 3.4.0-257432 Sat Jan 4 and hers is 3.4.0-722276 Sat Mar 15. I've used 4 different roms including DK 2.0 and DKX (Which I Love) and its the same thing. I've just stuck with the battery life. is this normal? Thanks for listening guys.lol

Since your GN3 is rooted, I assume that you are running Jelly Bean 4.3 since no one has rooted 4.4.2.
If so, you might try SafeStrap 3.71 and X-Note version 7. I had battery drain problems running the later AT&T 4.3 versions after the OTAs this year. After phone calls, my battery drain was at least five percent per hour. It used to be less than one percent per hour.
With X-Note v7, overnight I see 0.25 percent drains reported by Android Tuner. During a normal day with 25 minutes of phone calls, email downloading every four houses, some texting, and checking sport scores, I usually have 90 percent available at the end of the work day.
One of the biggest causes of battery drain is the dreaded wakelocks. They keep your phone from going to deep sleep and saving battery life. WakeLock Detector from the PlayStore works fine. I found that diagnostics.client.wakelock and NlpWakeLock. The latter can be stopped by turning off Location services. CPU Spy can show you the Deep Sleep percentage you are getting. At night, my phone reports as high as 98 percent Deep Sleep.

I'm actually running kit kat 4.4.2 and SS 3.72. Can I go back to 4.3? Meaning I'm still on the 4.3 (the phone itself) but I took the Odin update for 4.4.2 with Udroid. I hope I'm being clear. So the question is can I go back to a 4.3 rom from a 4.4 rom since I've already Odin flashed 4.4.2?
