Why does my iPhone turns off randomly and take hours to reboot?

[iMore Question]

it was still on 100% charge, and this happened twice now

It sounds like you have an issue with the phone. What model iPhone do you have? What version of iOS are you running?

I don't know why that's happening. It's possible you have a defective battery, or maybe even a corrupted iOS version, but I can't say for certain. Having said that, I recommend you make a Genius Bar appointment with the nearest Apple Store and have them diagnose the problem for you.

Sounds like a bad battery to me. My iP 5 has a battery that does sort of that way. Usually when using the camera on cellular. It'll go from 80% to the black screen in a second. But when I plug in, it's back up to around 80%. It seems my camera/FaceTime are the hardest on this old phone's battery.
