Sudden Battery drop

[aK13994]

I have recently purchased Sony Xperia L, the phone is excellent and has no issues until recently i found a bug in the phne's battery. Whenever my battery reaches around 50% it suddenly drops t0 43% or 45% in a minute when the phone is idle. I dont use any battery doctor type of apps but i do use Clean master. Suggest me a solution ASAP. Thanks!

Remove any kind of task killers or battery savers and monitor your device.
