Any customer rom can solve battery problem caused by OS? The problem can been seen from the pictures attached（the brightness is at lowest level and Os use cpu for 1h14m）, it seems that still do not have a clear solution for this problem. So could I through flashing a customer rom to solve the os problem?
BTW, I am using ke7 now.

try updaring to the newest firmware or set your display brightness low.
mine is at 27% but the battery holds long for me (6h music, web browsing, facebook 24/7, and 10 mimutes playing asphalt 5 HD) if thats your problem...
btw... i'm on lite'ning rom

The "Android System" usage can be reduced by using Titanium Backup and Freezing stock Samsung apps that you don't use / need (ie. Social Hub, una service for Samsung apps, etc).
The Android OS usage issue I don't think there's much we can do about until either Samsung release a 2.3.4 android rom or someone manages to get AOSP CM7 ROM released because apparently it's a known Android bug for dual core phones....
many thx

your usage actually looks pretty normal to me. 13 hours unplugged with 4 hours screen-on time, 22% battery left. not bad at all. i didnt notice what the android OS CPU time was though to make any assessment of that.
I adding some detail u mentioned in the original post, does that help?

Ok well your CPU usage is low which is good and means you font have the issue that some others have. I wouldn't worry too much.

I have Samsung Galaxy S2 with ICS 4.0.3.
From many days, Android OS is causing too much battery drain.
Nothing is running and even then battery is discharging rapidly.
Before that, I used to enjoy 40-48 hours of battery at normal use(only calls & sms).
The screenshot is attatched as a proof...
Please somebody help..
And please forgive me if a thread on this topic already exists, coz I've short time and I m really worried about it.

Download BetterBatteryStats from here (there is a thread), and charge your phone fully, choose kernel wakelocks and when phone is unplugged. When the phone has filly discharged, look at what is causing wakelocks (preventing phone from going into deep sleep). Look up wakelocks on Google and solve problems.

first of all, i dont think that this i anyhow abnormal - since you are using sammy rom, 15% for almost 8 hours gives you 48 hours time between charging.
in settings/battery you should tap the field with uptime, and you will get info about battery discharging - if there are blue bars showing that device is awake, but screen is off, you are probably experiencing wakelocks; then you should either uninstall recently installed app which could wake your phone, or install betterbatterystats and check what is causing wakelocks.

What does it mean?
Sent from my GT-I9100 using xda app-developers app
that means that you had only 1 kernel wakelock, and it didnt last even 1 second.
go to settings, battery, tap uptime and take a screenshot and post it.

yeah, thats the one. compare "awake" and "screen on" blue vertical lines, every time there is line at awake but screen is off, you have a wakelock (event that wakes up device from deepsleep and causes battery drain).
as i can see there are 5-6 short wakelocks which arent too important. you would have best battery life if you choose not to use sammy roms, but its a different story.

sammy rom = samsung stock rom

there is no easy solutions... but if you want to get deeper into system tweaking, you must read a lot, root your phone and use different kernels to see which one suits your needs best. i could suggest you resurrection remix rom v2.6.1 as one of the most developed ics roms, since jelly bean roms are still in pre-release stage. also a dorimanx kernel, because its most supported. using above combo, i have great deepsleep with almost 0 wakelocks, and about 5 hours of screen time with heavy usage (opera browser almost all the time, and opera is very cpu intensive browser). battery drain while screen is off is almost obsolete.

It's the stock Samsung rom you should do some reading in the original development section if your interested in rooting and flashing.

Wait for his reply before jumping all these premature conclusions. Simple
I already know what is causing his problems, but he has to first post his ROM & kennel details before i can proffer any solution for him.

Battery calibration apps don't work. The s2 calibrates its own battery. You can try to reset fuel gauge chip through extweaks if you are using siyah kernel, but I have not seen a difference when I do that

I have GSam battery monitor installed on my Note 3 (SM-900) running stock JB 4.3 (MK1) ....
Since a last few days I have witnessed battery drain on my phone without any apparent reason....I charge my phone to 100% at night (wifi & 3G data is off at night) & when I wake up after about 8 to 9 hours of sleep I find that the battery is down to 85% !!! Strange isn't it ...
GSam battery monitor says that nearly 67% of battery is used by "App Usage" , on clicking App Usage for bifurcation of battery usage I find that nearly 50% of my battery is used up by "Kernel (Android OS)"......How to control this , any help will be appreciated dear forum friends !!

No...
Do you have Google Now turned on? If so try turning off location reporting in Google maps and see if it helps, it's made a huge difference on mine.
Turning the location off helps. The GPS kills the battery.

Nobody can say without having any information.
Biggest reasons it'd have are:
1. Bad connection, your phone is search for good signal all the time and thus draining battery.
2. One or more of ur apps interrupt deep sleep of ur phone and let it drain battery.
If bad signal is the cause the only thing u can try is flashing another modem. Otherwise a new provider is needed.
If apps are the problem, you'd get greenify and hibernate all apps u don't need to push notifications.
If this problem still persist, download betterbatterystats and check which app or process is stopping deep sleep of your phone.
I don't think I have to mention GPS,wifi,bluetooth and automatic sync should be deactivated right?

You could also use greenify to close any apps that are still running when your screen is off. Also, you could try using a different kernel such as dorimanx or apolo.
