The battery was 88% at 10PM and at 6AM it was same 88%. I enabled battery saving mode and flight mode. Wifi was off. Auto Killer set on when the screen is off and Droidwall enabled for unwanted apps. I think this is good performance of Battery. by the eay, the binary count is 0 (inspite of flashing 6 custom roms). Thanks to Triangle away. The device N7000, Kingdoird V4 and speedmod #3.3.
