Two weeks ago I flashed 'Stock JellyBean 4.1.2 V7 ULTRALIGHT' from DevSwift1 on my girlfriend's Xperia U. The phone was finally running smoothly. However the battery drain is bugging her. Her phone is draining a lot of battery during the day while she is not using her phone a lot, her battery can't even hold out for a day.
Is there anyone else with the same problem? What could be the cause of this problem? How should I fix this?

Thanks in advance

More first get your phone's battery percent to 10%(or even lower) after that switch off your phone..and then charge it to this 3-4 Times (this method fixed this same problem for me)...if it didn't could be a kernel problem or something like that. So try to flash another Rom..
