This happens. Search the apple support forums - there are long threads on this very topic - especially with camera shutting down the phone. Always started with ios7, and can be fixed by a new battery. I recommend just replacing the battery.

At least yours is covered under warranty. Whatever caused it, swapping out the battery fixes it. Maybe it's an ios7 glitch that only affects some batteries. Maybe something happened to your battery. Swap it, get a battery with zero cycles for free.
