Default [Q][SOLVED] Battery drain extremely fast after upgrading to KK

My battery was pretty cool before (2.5 - 3 days without 4G) and now it takes only 20 hours from 100% to 1%. The drainers are Screen 30% (sometimes it ended up to 99% even I dont use live wallpapers or any 3rd launchers/widgets) and Android OS 20%.

Any helps?

Make sure to backup/sync all your settings and apps!
