[Q] Galaxy s serious battery drain problem by andorid OS

Samsung galaxy S 1 gt-i9000| rom- AOKP milestone 6 |devil 3 kernel
lately, I notice there is a serious battery drain. in 1 night, I lose over 35% of battery. (I used to lose only 3% Average each night..)
when I click on 'battery' in settings, this is what I see:
Android OS- 55%(!!!!)
mediaserver 6%
android system 2%
and more of course.. but its not important
I dont know what happened, and what the problem is..
NSTool settings:
volt- DEFAULT| governor- smartassV2 | min cpu: 100mhz, max: 1400| OC value: 100|live OC- taget low: 100mhz, target high 1400mhz| deep sleep- ON
min cpu load- 1% max 90% |ramp down step 200000hz | ramp up step 200000hz
down rate 49000us up rate- 49000us
awake idle freq 40000hz . sleep idle freq 10000hz
deep sleep information:
deep sleep(TOP=ON time(ms)1886234 avg(ms)7 deep idle(TOP OFF)= 0 0 Idle time(ms) 2120672 avg(ms)2
_________________________________________________________________________________________________
EDIT:
UPDATE-
Ok I have done factory reset+ full deletion.
installed milestone 6 (aokp) again and flashed devil (3) kernel.
no OC for now.. settings are set to default and have not been changed
still having problem: when I click on settings->battery:
first of all, it says phone is awake most of the time (why?)
android OC 3% (finally normal)
screen 17%
Voice calls 17% (its kinda normal too right?!?!?)
cell standby 8%
***android system 15% (normal or not? I think its too much doesnt it?)
**google services 26% (this is not normal I think.. when I click on that, it says included apps: google bookmarks sync, contacts sync, network location, google account manager, services framework (google account is not registered on this phone)
and more of course..
when I click on "android system" I see included apps: settings.key chain(wtf is that?), system UI, galaxy s settings, android system, theme chooser, vpndialog(what is this?), settings storage, google backup transport, settings. (is this normal?)

try easy battery saver app..
And u can also use help modem and semaphore kernel with any custom ROM...
If my post helped, don't mind hitting THANKS ;-)

Have you tried removing the battery for 10 minutes then booting back up?
This worked for me a number of times.
Sent from my GT-I9000 using xda app-developers app

I would also try to use another kernel (semaphore works good for me), if you don't have your battery drain anymore, try flashing back to your kernel (or wait for an update...)

easy battery saver app hsnt solved the problem.. still battery drain (but made that liitle bit better)
now im trying flashing another kernel.. (semaphore) and after few hours i will be coming back to devil kernel.
The problem might be with the rom? (ho and I have never done any factory reset/delete partition when I switch kernel or upgraded to another AOKP version)
waiting for more help.. ty everybody

Sounds like a rogue app is causing battery drain......instal better battery stats from the market and see what is causing the problem ....they have support website as well

Also try a clean flash, that would seem to be at the root of your problem, probably corrupt data or app data

The problem fore when I had Thais is that smartassv2 would stick at the highest frequency all the time. Try a governor like lulzactive and go to devil kernel 0.98.3. 0.99 has strange issues cause of the jb support

still looking for a solution.. just came back from semaphore to devil 3 and I think the battery is little bit better but still got serious drain..
1.what is "mediaserver" ? it takes me like 10% of battery.. what is that used for?
2. how to I apply backup for whatsapp?

thanks for helping every1
-problem hasnt still been solved.. even with another kernel
-all those battery saver apps are not helping..
-devil 3 is a good kernel right? I mean, it does not supposed to have any battery drain issues?
-titanium backup makes backup for game's and apps' date right? (whatapp conversation ..) ?

it is a very good kernel and if it has battery drains with latest version u can see it in the devil thread, if u like tweaks alot then its better to use devil then semaphore, but if u like a simple but smooth kernel then stay with semaphore ,both have a low battery consumption if u dont oc

Do you have any email accounts set to push ? I had serious battery drain with a few ICS roms when exchange email was set to push, setting them to manual or scheduled helped.

guys when I click on "battery" I see my phone is awake most of the times..
WHAT? WHY?
(and not im not using it.. it was during night!!)

Ok I have done factory reset+ full deletion.
installed milestone 6 (aokp) again and flashed devil (3) kernel.

After 2 months of normal behaviour on SlimICS+Semaphore kernel, my phone got the same problem today.
I have a feeling that "Google Backup Transport" is the main culprit. I have tons of such processes in "OS Monitor", that weren't there before.
Better Battery Stats shows nothing, I only have high battery usage for "Android OS" (29% - CPU: 9min, Awake: 2h 10min) of 9h total time.
And I have "Backup & reset" disabled in "Settings".
This option was causing battery drains on few of my friends phones, so I always suggest to disable this option!
I hope phone reboot will fix the issue automatically if not I will have to reflash my phone again!
PS: Google Play and Skype could also be few of the usual suspects.

Note getting hot after 4.0.4 after 20 min of use

I had the same problem with some kernels on 4.0.4.
I booted into Recovery, wiped cache, then wiped Dalvik cache and rebooted.
(Don't have to reinstall ROM. And it doesn't wipe your data)
Sometimes I had to reboot again.
Now no more heating.

Some application is making the processor run at 1400 MHz.. Check what it is.. You can install CPU Spy and verify if this is true.. Cheers..

Sorry guys ... all what you prosposed is not working ...
Tried wipping cache and Davlock ... still getting hot
Out of CPU Spy, I can see that when I am using Facebook app it is going to 1400 mhz.
But what is the solution ?

what kernel & governor & scheduler do you use ?
My phone gets really hot sometimes but it doesnt bother me, This phone packs some serious processing power - 2 CPU's, a HUGE LED screen, massive battery and a plastic housing... its gonna generate heat.
unless its blistering your fingers or frying an egg i wouldnt worry so much

Change the rom and use it for 20 mins or more without downloading any app from play store , with this you can be sure that your hardware has not damaged :good:

When you gion to use in this way install setcpu(root) and set you max cpu frecuency to 1000 mhz you goin to see the diference

Even i faced the same problem when i was using dolphin browser hd came to know from cpu spy
Just stopped using that app

Had the same problem with 4.04. After changing provider (new sim card). But I guess my installation got messed up a bit after a long time without wipes.
Never had problems before, but suddenly got a lot of FC on systemUI (tried a few 15 toggles, couldn't get them to work anymore. Also was suffering from the CSC unknown (and samsung keyboard Null error). And a very hot Note. Also, 10% battery drain an hour, even when idle and deep sleep.
Went back to GB. Factory reset. And reflashed LRG. And then again, the second time no CSC unknown and null errors on sammy keyboard. I traced the batterydrain down to exchange push service. Now I just pop every 15 minutes. No more heating, no more draining.

Interesting was it a simple deep sleep issue? I have exchange service in background always set to automatic and iam fine with GPS wifi and data all day long, for me I get 45% when iam home at 22:00 with moderate usage.

Not going into deep sleep!

I have always found the battery life to be poor but I have come to accept this device has a large screen and great processing power etc!
My UK phone is rooted on the latest ICS and has various apps frozen with titanium backup manager! It use to be in deep sleep mode for about 68% of the time but since 2 days ago cpu spy says it hasn't been in deep sleep mode! I have installed various apps that kill running apps but the phone fails to sleep!
Any ideas why it isn't sleeping, just sits at 200mhz!

Go to Settings -> Sounds -> Go to the bottom -> disable touch sounds. (Better if you untick all 4 options). Reboot. Leave phone for 10 mins. Check CPU Spy. :good::highfive:

Thanks for the reply, I did that when I first got the phone! Just checked and all the boxes are un-ticked!? Any other ideas?

Turn off custom power saving mode.. Check after that.. I faced issues with these two.. Sometimes even l2_hsic goes crazy and drains the battery.. Check that too.

Thanks, again this setting is disabled on my phone! Still sitting at 200mhz! Though the battery doesn't seem to be draining as much!?

hello sir..
hmm since i read that you installed various apps that kill running apps, maybe that is cause to kernel wakelock since your system always working to searching what app running and killed it in various time you set
..many system app that switch back on like google app no matter you turn off except you log out your account
or maybe you can try one off the famous airplane metode which is
- switch your phone to airplane mode
- turn off your phone and pull out your battery (until 10 sec or more)
- put again your battery and turn on your phone
- after complete reboot let it for a while then turn off the airplane mode

I had the same problem with audio_out one but only in imilka's paranoid Android.. Couldn't fix it in any way so left the rom..

the reason taskkillers are disputed is because memory works different on android. It reloads certain stuff afterbkilling it, causing a cycle of killing and reloaded that can cause more drain than is intended to safe

Battery Life with 10H firmware

Hi Guys,
I just want to share my idea to improve the battery life, I tried to test it already:
I did flash factory reset from 10E firmware and flashed 10H, then rooted(of course no problem with 10H firmware)
again factory reset, charge the 4X HD to 100%, install "Battery Calibration" it is free, calibrate your battery after 100% charging
After that I installed other than stock " Ram Manager Pro" it is not free, you need to buy from Google Play, set RAM to "Balance" for everyday use
create Swap file to your choice, but I kept 128MB, then VM Heap size set as per your choice, I set to 256mb, then tick "set on boot"
After reboot i installed "Root cleaner", you need buy from Google play, do "Quick cleaning" after cleaning, it is finished.
Whole night just dropped only 3% of battery life, i am using for every day use, no games, no other software install, keep stock.
I tired to flash 10E,10F and finally 10H showing good result, improved camera.

I have V10H and have no issues at all with deep sleep. Must be an app keeping the phone awake?
See screenshots.

Battery's duration is the same for me with V10H, as the V10F....

im using V10G and no need do all of this changes to keep 3% at night. Just remove bloatware, root , and run LG Gearbox with powersaver mode. battery duration about 22h on light use , 12h on gaming.

Installed lg gearbox: 2cores and 1000GHz and i have 0% loss during night!
I also get feeling that disabling some apk's ( like Maps or cell broadcast) can cause deep sleep problems (searching networks etc).
Also i found on two phones that when i root phone and freeze apks my phone somehow just drains battery during night... (from 100% to 20% !!!!!)
So mentioned method works for me and i don't want to touch it anymore - because battery on this phone is mystery.

I read that somebody under-clocked phone (800ghZ) and had unexpected random reset of phone.

hey sell your quadcore phone and buy a slow dualcore :silly:, thats a bad solution for better batterytime

Hi,
How do you switch to a different stock Rom?
I found a thread that lists many stock Roms but the links have been removed and there is no guide or flashtool to install a different firmware to phone.
Would be great of there was a guide and also a link for the v10h open Europe.

[Q] Battery problem

I have problem with my s3 mini.
I used stock ROM. it's still official without any root or something.
My baseband is DXAMB1.
My problem is, when I start my phone, the battery life up to 18 hours. But after 70-80 hours up time, the battery suddenly really sucks.
it just about 9-10 hours a day. For example (I forgot to screen capture), I charged my phone and full at 11 pm and then in the morning (6 am) it says my battery 50%. When I look at the battery status it says Android OS stay awakes for 6 hours.
After I restart my phone, it back to normal. When I woke up, it says 80% battery and Android OS stay awakes for 1 hours.
Everytime my battery life become sucks, I need to restart the phone.
Is anybody have the some problem with me? And how to fix this?
It just sucks that I have to restart my phone every 3 days.

Are you rooted, if yes try using Better Battery Stats from xda and find out whats draining your battery

I'm not rooted yet.
But Du Battery Saver said Android OS is draining my batteries.
Even in battery saver mode.
I will give screen shot after if it happening again.
Do you know why Android OS consumed much power?

I was pretty curious about this option too, some time ago, so I googled it and finally came to the opinion that it is like using a task manager, = useless on Android, because it has its own RAM manager.
This option to limit process is what it is: for developers, to test how their eventual app handle once it goes in background, and what if once killed. (read http://www.extremetech.com/computing/112013-how-multitasking-works-on-android-and-ios/2)
My personal advice/choice for a longer life for your battery:
1 - root your device and freeze/delete bloatware (system apps: first freeze them, see how it goes, then, delete them (after making a backup)
2 - use
A) Juice Defender (balanced or aggressive), set 2g connection when the device is in your pocket,
B) Use Wakelock Detector to check what most consumes your battery (https://play.google.com/store/apps/details?id=com.uzumapps.wakelockdetector&hl=en)
3 - use wifi and 3g only when needed, - don't count on the smartness of automatic mode 2g/3g under data
4 - switch off syncronization if you don't need it 24h (whatsapp / viber will work anyway)
5 - settings / display /
A) Auto adjust display tone ON
B) Turn off softkeys (I know exactly where 'back' and 'option' keys are..)
6 - Power saving mode ON for screen and cpu (http://www.youtube.com/watch?v=XTLTBo2DRQA)
7 - Disable double tap on home button for S-Voice (http://www.youtube.com/watch?v=OmU8hXUXNFE)
8 - Keep normally a mid-low brightness level, you can adjust it quickly if needed, can't you?
9 - Disable Auto-update in Google Play (you can update manually)
10 - How To Disable Samsung Push Service and Samsung Ad Utility Services (http://www.eyes4tech.com/2013/03/ho...e-samsung-push-service-and-samsung-ad-utility)
11 - Turn OFF vibration (actually, I like it and I use it for SMS and incoming phone calls)
12 - Set airplane mode when you go to sleep (or just switch it off if you don't count on it for morning alarm or to use it as an eventual light)
13 - Never use a Task manager
Assuming you're enough smart for keeping Bluetooth OFF if you don't need it, by this way, according to my daily use (phone calls, texting, internet, no gaming), I recharge it each 1d 15/22 hrs.
Hopefully this helps. :cyclops:

I'm using fb, twit, whatsapp and line as 4 background process and working as usual.
Here is my RAM Usage and my battery up to 18-20 hours with 3G connection always ON.
