my phone battery draining very fast! it was fully charged 100% at 1:30 PM, and now 69% and its just 5:20 PM. I did not use it all day!!
I received the phone three days ago and since I been reading articles and how-to's to help minimize battery draining but without any luck.
so have you got any idea if i do a fresh install for iOS will my iphone lose its official unlock?
