This sounds like what's going on with my phone. I have found that once it's running again as a newly setup phone it stays on unless nothing is running. I've had a white noise generator running since Friday and it hasn't crashed again yet. For me it seems safari related. My next thing is to try a new iCloud account and never use safari. That way no safari data comes over from my existing account. I'll post about it if it works.

Did the same situation happen after you flash your iPhone?

For me the situation continued even after being reset to factory settings at the Apple Store. Though, mine doesn't require the battery to drain. It just has to sit quietly for hours.
