Set it up as a new device. Something with your restore file must be causing the problems.
I did this and the problems persist. The only things I restored were my texts and I reinstalled 1password and the battery life has actually gotten worse.
Could it be related to having iTunes match? I notice the music library tends to flicker on the phone.
[doublepost=1452318666][/doublepost]I should also note that on NYE I installed the aforementioned ad blocker and battery life was great! I only lost 10% over 5 hours, but it seemed to be a one off since on New Years' Day the problems returned.
