Helloy guys will the kernel I told above 10 hours maxmium battery without touching the phone you know what does this mean it means without doing anything only alarm rigs 6 min and switched off the battery finishes in 10 hours why??
CM7 300-1000MHZ
for more specific deep sleep(by cpy spay) is 97%
Battery use
Mobile stand by 48%
phone signal 38%
Android OS 4%
display 4%
also the charging is too slow charging 1% / 10 min
It's CM7 bug. Heuxxx kernel is good, but it's old. Doesn't have latest CM7 commits which fix aspects of the kernel code.
Try boype's kernel but i still get max 16hrs of battery use on any CM7 rom. I think it would be wise to stay away from CM7 based roms until a fix comes if battery drain is an issue for you.

hello,
i've had my SGS for a little over a week now. from day one i noticed battery drain but i thought it was normal for a new device. i flashed darky's 10.1 extreme on the second day i got it because it was very slow and had a lot of bloatware ( i wasnt very patient and i flashed at 95% or 96% battery), the drain was still there. i let it go through a few recharge discharge cycles and no improvement, so i used an app from the market called "batterycalibration" by marosige, no improvement and it the reading would drop to 99% or 98% after taking it off the charger.
i did a little digging and discovered i had the android os bug (was over 50% usage usually) so i used titanium to wipe software update and samsung account, and froze the first, didnt help by much
i then flashed darky's again at 100%, and now it still reads full charge after removing charger and android os bug i gone (reads 4% system and 4% os), but drain was still there. i emptied it to the point it couldnt turn on anymore then charged it from wall charger while turned off to 100% while i slept
i woke up and tested it by playing a game (Blastmonkeys) for like 20 mins and the battery went down to 90%, that was less than 2 hours ago, and now its at 87% and it was completely idle
notes:
my brightness is turned all the way down with no animations but display reads 54%, wifi is usually on when im home but battery stats show 6% wifi so i dont think its a big problem
also, the device was bought locked in france by someone else and im in egypt, so i dont know anything about warranty..
im sorry for the long post but i tried to be as detailed as possible...
hello,when i upgraded my sgs to 2.3.3 i also got battery drain and android os was consuming hell lot of cpu about 70%,..,.,then i flashed 2.3.4 jvp i didnt get any battery drain in that firmware then i upgraded it to 2.3.4 jvq this also donot have ny battery drain..,,.i recommend u to flash it and try it once
will try, but isnt darky only compatible with JVH? what happens if i change to JVQ?

see jvp and jvq are bug fixing firmwares and i didnt use any custom rom ,..,i have stock firmware which i just rooted and didnt use any mod or rom.,,.,.jvp and jvq are stable roms diffrence between the both is that in jvq browser is improved gallery improvement,.,..,etc
As far as I know, the percentage not being 100% after unplugging is normal. To prevent wear on the battery, the phone cuts the charger after reaching 100%, and restarts charging when it reaches ~95%.
I don't think a 3% drop in battery over 2 hours is uncommon. Wifi and data connection will pull a lot of power if on, even in standby.

Normal, this phone drains about 20% battery per hour of screen use, slightly less when watching video.
2-3% drain over 2 hours is also pretty normal if you have wifi/sync on.

I just got my SIM card replaced today. The one I had used before was about 12 years old. So whenever you-re having battery issues, make sure your SIM card is not the cause for it .
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!!!
Last week I thought I'd try [CWM]AllianceROM N7000 ICS v2.1 and it was lovely but I think I started things going wrong by flashing notecore 13 kernel cause after that the battery started going flat withing 12 to 16 hours. So I thought I would go back to faithful [ROM] Criskelo's ICS V11.2 << LRK 4.0.4 yesterday afternoon and flashed with the latest speedmod. Over night with no phone usage the battery went down 40 %
Any help or advice would be appreciated thanks
Looking for a solution to my note battery power drain
Sent from my GT-N7000
probably deep sleep issues,
get cpuspy to confirm. You can reset stats to measure timeframe from zero again.
then if percentage is low, get betterbatterystats to check what causes wakelock(not letting phone go or stay in deepsleep)
Here you can set custom reference to measure in same time period.
Check partial wakelocks, which ones run for approx same, or long time as the time outside deepsleep, minus the time you wake device yourself.
note dont wake every 5 min, but couple of hours without touching phone. Otherwise your the wakelock lol

Thanks for that will try what you suggested and see what happens
I reset the starts for a fresh start, the results where
800 MHz 15%
500 Mhz 12 %
200 MHz 55%
Deep Sleep 13%
I have no idea whaat this means lol,. thanks again
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..
...
This is the first time I have flashed a custom ROM.I recently flashed the latest stable CM10 with the JB semaphore kernel and its been great so far as far as performance goes. But the main issue is the battery life, on moderate usage it seems to only last 10-12 hours. I tried the usual fixes like changing my modem, battery calibration and also making sure the com.media.process was not running continuously(using better battery stats app), and it seems to have slightly improved.
Questions are
1)Is this normal battery life to be expected from CM10?
2)Does CM9 have a better battery life than CM10?
3)Are there any other JB roms that will give me a somewhat bug-free plus high performance/good battery life?
4)Is the current stable CM9 more suited for everyday usage than CM10? I read that CM10 still has lots of bugs and issues?
Thanks in advance guys
My battery in JB lasts for maximum 10 hours
So there are no JB roms that have good battery life?
This is very important question for me, need to know witch ROM is better cm9 or cm10? battery draining extremely fast(8 hours aprx.)
Did someone tested this issue?
I'm not sure if I want to downgrade even if the battery life is better but I'm interested in this matter too.
Actually my only issue with JB battery life seem to be a rom issue ...
Yeah there is clearly something wrong with your installation. I am running CM10 Fishears Nightly, JB Semaphore 2.6.0 Old, XXJW4 radio and I usually have about 70% battery left at the end of a working day when I put my phone on the charger as I go to sleep. On a usual day, I listen to about 2hrs music on the train and do some light browsing/games throughout the day.
Here are my Semaphore settings:
Governor: Ondemand w/ Smooth UI enabled
Active scheduler: Simple I/O
Deep Idle Enabled
SAI Enabled
SD Card read ahead: 256KB
Normally the only apps that run in the background on my phone are:
BLN
Voodoo Sound
GO SMS
Settings
SwiftKey
WidgetLocker
Widgets
This way I don't have crap pulling my phone out of sleep all the time. On CM10 you should be able to get at least 2-3 days out of a single battery charge.
here my batterystatts i use stock cm10 with the newest nightly and the stock kernel sheduler noop govenor ondemand my 3g is enabled and i use more or less hole day wlan. i have the original battery.
