Problem Encountered : iPhone turns off without me knowing. To be exact every couple of hours. Then i would have to turn it back on. Sometimes, it wont turn on att all and the only way to make it alive again is to charge it. Never happened before this. It happened for 2 days already.
Steps Taken So Far : Soft reset, deleted unnessary apps, do memory cleaning, sync with pc.

Hello again guys.

Any idea why does the phone suddenly drains up the battery so fast? As in the battery will drop from 100% to totally flat overnight. Its really bothering me.. Started happening 2 days ago.

All unnecessary stuff, wifi, push is turned off.
