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.

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.

The screen uses the most energy. Pretty logical for it to be on the top. If you're not using your phone for a day, of course the android os process will be at the top.

Boot into recovery and wipe cache and dalvik cache and fix permissions. If that doesn't help, download BetterBatteryStats and see if apps are causing kernel wakelocks (not letting your phone go into deep sleep) meaning keeping it awake and using CPU.

Without any other information this history information is absolutely useless. If there is any problem at all you can solve it by doing what themadba suggested in post #3.

The battery history you posted is plain useless.
However, if you have autosync enabled, then disable it

Hi,
I am using Omega v34 ROM and battery very, very bad. On stock rom I had, at least one full day of usage, but now it is a figt to go through working day (7-9h).
I wiped battery stats following a procedure, but that didn't help at all.
And one more thing TouchWizz is crashing at least 5 times a day.

You would need to provide more information.
Have you check what's draining your battery? (you can find a general list in settings--> battery)
You should also try to use better battery stats and ask on the BBS thread/forum for help there to see what the culprit is.
I have between 8hrs to almost 2 days depending on usage.
It seems like screen is using allmost 40% of battery.
Sent from my GT-I9300 using xda app-developers app
set it to automatic brightness. Also use better battery stats and do a full day or night log and ask for help in their forum to see what might be draining your phone.
Sent from my GT-I9300 using xda app-developers app
As mentioned above, sounds like you might have a wakelock somewhere. You can identify any rogue apps with better battery stats and then uninstall or freeze them. Try using power saving mode, you shouldn't really notice any decrease in performance but your battery life will improve. You should be able to get screen on time off about 3 - 4 hours.

Stop using those apps. They use more battery than they save.

"battery saving" apps are really bad for your phone to begin with. remove that junk first. It's probably one ofnthe culprits keeping your phone awake.
then do the BBS thing I mentioned earlier.

Issues connecting to unsecured wifi hotspots
Using Omega v34 and love it! but when I try to connect to my unsecure wifi at work it won't connect. Please help
There seems to have been quite a lot of discussion regarding issues with battery life on Omega 34, in the Omega thread. Because of battery issues that some people are experiencing, Chris_84 has a suggestion in his FAQ (question 27).
You could try a different kernel. Apparently the Yank kernel is pretty good for battery life (I use Siyah version 1.8.4 with Omega 34 and get brilliant results, but then I don't use my phone that heavily. The Siyah kernel allows you to tweak some settings that help with battery).
Also, a lot of comments in the Omega thread talk about installing BBS (Better Battery Stats, as per the comments by mputtr) and posting the log file into the BBS thread (or even in the Omega thread).

Not sure, but have you tried;
a) Removing the WiFi profile off your phone and setting it up again.
or
b) Reset the router (if work let you)...
Hello, I do hope this hasn't been answered elsewhere and if it has, please point me in the right direction, that would be much appreciated, I have a samsung galaxy s3 i9300, I have ran various different roms, cm10, pacman, and now ultima rom 12.1 with Persues and Siyah kernel, anyway the issue is. I have tried with both these kernels that I would change the default profile with an app to change the settings. The settings have been changed and set on boot. But the battery change wouldn't change, or it would but after a reboot it would drain just as fast as if settings weren't applied. Or it comes and goes. Any help would be greatly appreciated. (I once got 2 days with Siyah) but never again. I don't sync.. Or have high brightness.

did you try to use BetterBatteryStats to identify where the battery consumption is coming from?
Yes I did. But it's nothing changed. When applying the settings. Even BBS doesn't change or show adormal things
Sent from my GT-I9300 using xda app-developers app
We dont really know if what you're getting is abnormal. We'd need screenshots.
Here are the recommended screenshots:
When Battery is nearly empty....
Android Battery Stats Page
Android Battery Stats GRAPH page
Android Battery Stats Screen-on Page
BetterBatteryStats Kernel Wakelock page
BetterBatteryStats Partial Wakelock page
(Set BBS to report from "Charged")
It is abnormal when battery drainage changes when I'm not doing or after a reboot. And battery is high or normal as if no settings are applied. However I'll get the following screenshots and report back tomorrow

Hello! I usually get about 2 hours of screen on time on my GS3. After doing some research, i found out that 2 hours is not very good...so I have some questions. Take into account that I have tried to minimalise the us on my GS3 and also watched battery tips and tricks videos and even flashed bestMultitasking fix already.
Is there someway to improve my battery life?
While making this thread, my battery dropped from 36 to 34, using wifi and power saving on...also, my signal is full, so it's not a problem from cellular reception
get checkup of your battery and apart from that also goto settings>battery and see how which activity uses the most battery

It seems that Android OS is killing some of your battery life, this usually only happens when you flash a custom ROM, Id suggest finding out what is killing your battery, download an app called wakelock detector, itll show whats using what
Also, the Greenify app is amazing, it wont let any app you chose to run unless you click it.
You could try turning on your power saving setting, itll slow the phone right down ( thats why i hate touchwiz ) but itll give you an extra 30 minutes of screen on time
Theres always custom Roms and kernels too, Ive got the Illusion Rom which ate up the battery for a day ( every new ROM does this ) and then applied the Googy Max kernel, Im running on 800 mhz with undervolting and still silky smooth
Also, try disabling Google services/ sync and disable Google now, for some reasons they seem to be the issue in most cases

This was today's usage...I don't get it. I guess that media server is when I play music through bluetooth in my car. Still, very bad screen on time ...
the factors that affect battery life:
-screen brightness
-bluetooh connection
-wi-fi connection
-gps
-3G/2G connection
-synchronization
-wallpaper
-vibration
Get zerolemon battery i can get 11/12 hours screen on time with juice to spare!
