[Q] CM10.1 Android OS Battery Drain

When I install any CM10.1 ROM, it has decent battery performance but as it gets older (and more apps installed), Android OS starts sucking more than 50% of the battery. The battery life reduces to around 1.5hours of screen ON time.
I've tried almost every ROM for CM 10.1 and problem is consistent. How Do I fix it?
Following screenshot is for battery overnight (screen not turned ON at all in 8hours and battery dropped by 20%)

Check for the Google backup feature. It could be using the battery and data usage.

read ahalfords sticky on wakelocks, try identify drsin by actual cause, might be an app that causes it and the os
build in energy overview is really crap on identifying true cause

your going to have to download betterybatterystats or gsam battery monitor. just that screenshot wont give us any useful info to go by to deduce why your android system is so high. though it is quite common from what i'm seeing and what i've been testing on multiple roms and multiple kernel setups.

Helpppppp pls
Can someone here can help me with the same problem as the guy mention
i have 90% Usage from Android system.
What to do ?????????

Android OS accounting for more than 50% of battery.

As nobody seems to answer I want to start a little poll.
How is your consumption when surfing?
On GSM they proclaim about 14h web browsing. With my data it comes to 6 hours, if you add the screen consumption.
Maybe some of you could take a look in the settings under Battery & Performance to see what the respective browser consumes roughly per hour. Other devices / any browser are also welcome.
Thanks a lot!

Battery Level went down 46% within 22 minutes

Hello,
Please advise how to gather the needed data from the app. According to Battery Historian there is something which consumed 46% battery life between 14:52 and 15:14, but I don't know which app or process. There is huge percent of battery consumed given as 'Unaccounted' and there is no UID (attachments for more). I have some apps in mind which could cause it, but I am not sure. I thought about that apps which are not listed in the Apps (with Uid) section on Battery Historian (All apps listed here [Battery Historian] have Uid, so the apps which are causing the problem should not be here).
So what reference/data/stat should I look at? Thank you.
