Killing my battery !!

Rooted and installed assonance 5.2 and put on some other apps now something is draining my battery like a mother!!! I literally watched it go down by 10% in minutes. Anyone else experienced this? How do I find out which app is the cause of this without having to uninstall each app?

download OS monitor or system panel and see which apps are consuming or hogging cpu

I did that and nothing looks out of the ordinary. I'm so frustrated!!! Could it be the rom or is it an app?

No help here...........I got tired of the battery drain from all the custom ROM's I tried (just about all of them) and am now back to JH7, getting almost 32 hours before being drained. I have done some tweaking to it, got the GPS working great and everything works whereas with some of the ROM's something had to be sacrificed.
Here are some screenshots:

In the last screenshot it shows 30 seconds to lock, all day today I was around 10 seconds to lock and 10 satellites.

Did you flash with 100% battery and then calibrate your battery afterward?

No it wasn't at 100%... And no I didn't calibrate the battery... Was I supposed to??

It's certainly worth a shot. I had the same thing happen to me once a while ago and it seriously extended my battery. There's some threads here that describe the process which essentially involves discharging and charging your phone off and on and deleting the battery stats through CWM.
I always flash a ROM with a battery showing 100% and I typically net pretty good battery life doing it this way.

Always recommended to do so whenever you flash...........YMMV

Here's a great thread for you to look at.

So can I just calibrate it now or do I have to reflash my phone?

You can calibrate at any time. No need to reflash.

Maybe before you reflash, please wipe of the factory settings and partition and also the Dalvik cache and battery stats in "Advanced" settings using your Clockwork.

Ok I'm trying one of those recalibrating methods. Maybe I really should've read everything before I flashed... but there was sooooooo many stuff to read and watch...
When you say "advanced" in clockwork, thats the rom manager correct? when i look through it it says advanced mode for premium users only... is that the right app?

I'm sorry but now that I search through the forum I see that its a common problem and it's something I missed. I'm totally new to android (smartphones period) phones and flashing and stuff. Thanks for all the helpful tips!

One question though. When you delete the batterystats.bin file, does it get recreated at a later point or never again?

It gets recreated, yes.

Have to remember as well that each user may see different results with the same Rom. Kernels. Modems, Roms perform differently from one device to another based on a multitude of factors. After you have done the basic steps to try to stabilize battery drain, I would then begin by experimenting with different kernels and modems.
Idle drain is the test I normally use after ensuring proper battery readings, sensor usage and app CPU behavior. Many times simply flashing to another kernel shows immediate results.

I've yet to learn about flashing kernels. I'm now running perception 10.2
Sent from my SGH-I897 using XDA App

Download the sgs kernel flasher app from market. Go to kernel thread off your choice in captivate development an download kernel, placing the file on your internal sd card. Run the app which is poetry self explanatory.

Definitely try a different kernal or modem. Generally, you can find feedback in the rom thread about what kernal or modem gives the best battery life.
I haven't used Assonance but I had to flash the firebird 2 kernal to get good battery life with Perception 10.2. Keep trying.

Calibrate battery

Hi guys, i'm having the issue with my battery is only capable of charging till 98%. I mean, it's not that much of a problem, but is there any way to calibrate the battery again? Thanks in advance,

Try to completely empty the battery by rebooting after your phone shuts down because of low battery. Keep rebooting it after it shuts down again till it doesn't want to boot anymore. Till the battery is completely empty.
Then Charge it again and leave it on the charger for more then 20 hours.
Don't know if it's gonna work but give it a try
EDIT: Q? are you using a custom ROM ??

Ok I'll give it a try, thank you. I have this problem since i flashed a modaco firmware and wiped my battery cache via cwm. Anyone else having those issues?

I reverted back to stock on my O2X and I can get 48 hours out of the battery. I had the same issue as you and reverting back to stock seemed to cure it too.
Just an FYI I thought I'd share.

48hours when you are using him or 48h max on standby

USE phone heavily. Use it till the system turns OFF automatically
Turn OFF phone
Charge till it says it is FULL
Start phone in RECOVERY Mode
Select Advanced CWM Features
Select Wipe Battery Stats
RESTART phone

Sorry, should have given more detail. That 48 hours is with general browsing and social networking with a fair bit of video recording and camera use. No 3G though. All data was over WiFi.
Certainly not just stand-by though.

No full power use of the processor i understand

i thought i had the problem too with the MDC fear 5.3 but it just jumped from 98% to 100 after 10 minutes so its probably a mistake which solved itselve if you charge it long enough.

Didn't work for me, i did it exactly this way, charged it for about 10 hours, booted in recovery, wiped the battery stats and it stills shows 97% when i boot it. However, it's not a disastrous failure, i can live with it and hopefully it gets fixed sometime.

Finally, i found the solution for me. After i reflashed the stock rom, where this problem doesn't occur, i flashed a modaco rom again WITHOUT WIPING THE BATTERY STATS. Now it's all working fine, i charged my phone to 100% a few minutes ago. Hope it will help some of the people, who are still having problems.

Does kernel version has anything to do with this issue?

Don't think so, i tried the stock, Paul's kernel from FR12 and the EternityProject Kernels 1.3 and 1.4, it was all the same until i tried reflashing without wiping battery stats. For the record, i flashed the new TK-Rom V 0.6 with the EternityProject Kernel 1.4.

Battery drain xxjvp

Anyone know why Google Services has such high usage percentage in battery use(almost 50%)? A solution maybe?
Sent from my GT-I9000 using XDA App

I'm on jvp and have got no drain problems yet. Does it go away after a reboot?
Sent from my GT-I9000 using XDA App

no it doesn't. It shows that Google Services is running,and the processes are Network Location and Google framework.. I can't unninstall the framework,because i can't use the market after.

If a simple reboot doesn't fix it then if you wanted yo you could do a factory reset using this code *2767*3855# in phone dialer. This will delete everything on the phone and reinstall the firmware. But it will delete everything! Also any lagfixes should be reverted back to rfs before using this code.
There maybe another fix but that's all I can suggest for now.
Sent from my GT-I9000 using XDA App

Did you just flash the rom? It is expected that Google Services will consume an unusually high battery after flashing. It is because google account has to sync data from phone to its servers and vice versa. Let it run for a few hours or until the initial battery runs out. After that I think your rom's battery usage will "settle down".

Battery drain seems to be fixed with 2.3.4 for me.

Do you have Latitude activated?

+1, i have one day on Stock JVP with SpeedMod kernel and battery life is rock solid! about 1-2 % per hour in stand by.

This is the 3rd day with xxjvp. My latitude is unninstaled.

wow.. 1-2 % per hour in stand by?? i think something wrong with my battery.
I unplugged at 9.00 am and drain sooo fast.. 15% left at 1.00 pm!
but with 2.3.4 with speedmod kernel it can last up to 6 hour.. still this is not like others right? I

You must wipe the sdcard because it might have things from previous roms

[Q] Battery life - my sisters I9000

Guys, my sister has had her I9000 for a good few months now and everything was fine until recently.
She phoned me (knowing I like my phones) saying her battery life had become really poor over a couple days.
So I took the phone off her and updated it with Kies, so now it's running the latest Kies Gingerbread for that phone. I should point out it is not rooted, completely stock.
I noticed some crummy looking app's like Android Anti-Virus and Task Killer so removed them hoping one of them was acting the goat.......everything seemed to be going good until yesterday and she charged the phone all night until 8am and when it came to around 2pm the phone was flashing up with low battery alert. She said she had used twitter a little and browsed on the internet a while.
I have told her to get CPU Spy and look if the phone is going into deep sleep, yesterday it had 0% deep sleep and today it is saying 70% deep sleep even though the battery only lasted 6 hours before low battery warning...
Any ideas what I can do to track down where the problem is? Would she see better battery with ICS or a custom GB ROM?

Mine did this on stock ROM luckily mine lagged when I went into battery use it was Samsung app push update service or something like that but thanks to the lag it showed sleep lock before it shower that service I uninstalled then it could go back into deep sleep

it will root your device and install clockwork mod, should fix the battery issues though. Try flashing the CF root kernel via odin. Theres a tutorial in the thread.

After the odin flash, you can use titanium app for remove apps or system apps unnecessary

Best kernal for SM9 Rom (Battery preferred) ????

did you wiped battery stats in cwm? If not charge the battery to full first.go to cwm.wipe it under advanced.reboot phone.let the battery drain out.then charge to full again continuously.
You can use battery calibration from playstore also for the same purpose.

Okay I will try that...when u say let battery drain out do u mean I can still use it until its very low or until its un useable? Thanx Mr

yes, use it until it turns off and then put on charging and full charge it, if possible then in switched off mode only, repeat this for 2-3 cycles, it's best way to calibrate battery.
Recommended to follow this whenever you flash new rom.

I've not yet wiped batt stats yet but I going to give it full charges and let it run out and really charge again and see if that helps. Reason why is I never normally full charge it...I just charge it half way at times so maybe my battle might not need calibration.
