And welcome to the topic of the thread... that's my point... my phone logged 45 minutes of usage while I was sleeping. Additionally I power cycled the phone before I put it down for the night, so nothing should have been running.
It's abundantly clear that something is running in the background, eating through everyone's batteries... if we all knew what that was this thread would have ended days ago.
I have FAR LESS than the default options enabled out of the box, and my battery life is 5x less than promised by Apple... so either they are fluffing the numbers, or the phone is having an issue. Maybe it's just mine, I'm just reporting what I'm seeing.
Exactly what happened to me. New iPhone, not having this problem.
