IOS10 Battery drain
I got the impression that the battery life on my iPhone 6 has decreased dramatically since I have installeer iOS10. Battery drops suddenly from 80% to 37%. I didn't have these problems with iOS9...
iPhone 6, iOS 9.3.3
I had the same problem. In fact i realised that when i enter in Messeges, thebattery goes down really fast and the app crashes. I had to go back to 9.3.5.
