iPhone battery decreasing dramatically
Last night i was trying to back my iPhone up to iCould and i tried to restore it to original factory settings but then I gave up. I charged my iPhone 6 to 52% last night and when I woke up, it was down to 43%. I then turned on wi-fi and went on Snapchat and it jumped down to 33%! I then reset my iPhone by holding the lock button and home button and it went up to 35%. Not too long ago, I updated to iOS 9.3.1 and i am in the middle of restoring my iPhone to original factory settings.
My iPhone has never jumped down like that before that until this morning.
iPhone 6, iOS 9.3.1
