[Q] Extreme battery drain

I am experiencing an extreme battery drain with ALL the roms i tried.
The battery lasts maximally 5h, with 20-40mins of 3g browsing.
Currently at 38%, display max brightness, 2h 12mins usage,78% in battery use / Opera Mobile usage 22 m
ins, 9% in battery use.
13h since last recharge (i went to sleep).
Also my battery magically charges itself while on standby, up to 4% per hour.
Im pretty sure my battery is calibrated, even if it isnt it would give me the same power.
Also it heats up to 59c (even when i wasnt on 1.2GHz kernel)

I think u need a new batt. Same thing was happening with the iphone and untill i've replaced the bat the same thing happened.

.
Thought so.
Will flash stock 2.3.5 or should i flash 2.3.3, which is the latest official for my network?
I think it doesnt matter...
Well the guys in the service are a$$es so it will take them about 2 weeks for it...

i'm not sure tere is such thing as stock 2.3.5 and i think only MIUI has this. Last is 2.3.4 but i might be wrong.

There is xxjvs that is a 2.3.5 firmware

No your battery isnt wrecked neither magic took place its just that ypur battery stats are messed up!
Fixing them-fully recharge your battery until it shows 100% then switch your phone off and then let it charge for another 1 minute then go to recovery mode( you have cwm recovery right?) Then go to advamced then delete battery stats from their and reboot your phone ! Then for best result ypu can fully drain your battery to nil unt it switches off! Your battery stats should be now fully fixed ! Dont worry for deleting battery stats system will make them again in a few minutes or on a reboot !

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.

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] Automatic Battery Mis-Calibration

Currently Running
--> GingerDx V023
--> Stock Kernel.
I wiped out battery stats from CWM just after flashing the new ROM , but after calibration , and after charging the phone the battery gets mis-calibrated and gives me an error in battery percentage of about 20-25%
I calibrate again , and then again it mis-calibrates again.
To explain more , Suppose I have full 100% battery and I calibrate battery. I normally use my phone , and restart my phone after listening to music etc.
I get true and correct battery percentage every time I restart.
But when I charge my phone when it has about 10% battery , it charges up to 100% in about 50 minutes.
And when I restart my phone , it says I have only 77% battery left.
Mis-calibration is only when I charge my phone , not when I am using it normally.
I am not having problems with battery life as such when I finally manage to charge it to 100% after restarting my phone several times to actually get it fully charged (about 30+ hours of moderate usage after full charge) , but I don't get the true battery percentage on my phone when I charge , and my phone doesn't charge to its full capacity in one go.
I re-flashed GDx V023 three times , but the problem persists. I tried all calibration techniques and apps in the market but failed.
What can I do ?

Did you ever try to full wipe your system?
Try to full drain your battery after calibration,
maybe it will solve your problem.
Sorry for my bad english,

Initiated full wipe each time.
Not tried full drain yet. Let me do it and then see if it works .

Sounds very much like a problem I encountered with my spare battery (actually, 2 spare batteries). It also appears to (in part) depend on the ROM. Stock ROMs don't seem to have that problem. Consider it a kind of tradeoff for whatever benefit you're deriving from your custom ROM.

Still not able to fix
Not sure what I can do.
Never had this problem with GingerDx V022

you can revert back to GingerDx V022 if you want better battery life

I wish I hadn't had to revert back
But that's what seems like it now.

[Q] just wanna ask x8 battery life

hello
i just wanna ask something about my battery life on my x8...here's how it goes first i fully charge my battery up to 100% until it says on status battery full...then i unplugged it..after it i texted for a few minutes...and i check the status of my battery and it says: 28 mins 23s on battery..my battery is on 96%..is this normal.? or somethings draining my battery,?
i use minicm7 2.2

this is normal since battery is heating itself while charging, and when it cools down it shows less percentage of itself... to maximaze your current battery life, calibrate the battery:
1. charge it to 100% no more no less
2. leave the charger PLUGGED IN, and reboot to CWM
3. there you should find somewhere under options or advanced "wipe battery stats", and you press that
4. reboot your device and when it starts up it will show about 91%, charge it to 100% and you have your battery calibrated
NOTE: the charger is always plugged in

ok thanks i'll try it... one question should i drain the battery before calibrating it.?..as in zero percent??

Yes , that is recommended.
Also , one advice from me.
Even after calibration , whenever your phone says 100% charged , reboot it while the charger is plugged. You will get the exact battery charge after reboot.
Do it every time your recharge your phone.
Then stop rebooting when you get a 99% or 100% after a fresh reboot. Trust me , it helps.

ok thanks for the advice i'll try that too...

it is normal dude ....mine is giving 1day on heavy use

use zepplinrox's supercharge script...it really made a CONSIDERABLE change to m battery usage time

I have one question: "Why my battery is giving 6-8h. My battery 2 days ago giving 24 and more hour." Sorry for my English, but i am from Poland

what happened 2 days ago? did you install new ROM?

The OP might not have needed to install a new ROM, just an APP or maybe just a combination of APPs running. My phone sometimes canes the battery in a couple of hours from 50% to nothing for no apparent reason. On both stock and custom (actually better battery life on custom) it lasts about a day but sometimes about 6 hours! Not sure what is going on as this happened on both the stock 1.6, 2.1 and the custom 2.3.4!

Need HELP with CM9.1 BaTTERY

Guys please help me!!!!
My battery DRAINS even if I don't use WIFI BLUETOOTH .... or something like.
It just drains ,I want another kernel like battery extender by libiSC but some that is compatible with CyanogenMod 9.1 (RC2):crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying::crying:

Welcome to my world.......
Ever since i flashed nims kernel v2.2or so, my battery's been behaving weirdly: after a full charge, it goes down normally.. But when it reaches 80%, it starts dropping rapidly no matter what i do. A minute later, its 75% and it will stay there for a long time.... before dropping drastically again. at the end. i still use up my battery within 1h 30min or so with lite 3G usage... As you can see from the screenshots taken from Settings>Battery.. Another weird thing is that when i reboot my phone, the battery level increases... e.g. i was playing angry birds that day, batt. dropped from 84% to 66%. ( i played for around 5 min with 50% brightness). And when i rebooted, the batt. level went from 66% to 79%! Was very shocked.. I hope there is another battery efficient kernel for my phone. Im on unofficial CM9 beta 10 MaclawStudios. I have changed my battery and STILL no difference. I have trird to flash firekernel but my fone fails to boot... Pls help me..
