So I wanted to see if anyone else has seen this. My 7 shut off twice tonight while doing an Instagram live stream, I was out wandering the woods looking for some photo opportunities with my camera (not iPhone camera..) when out of nowhere the phone generates a VERY quick message on screen which I couldn't manage to read and then it goes dark. Weather outside is about 20F so it shouldn't be overheating. The phone then takes at least 3-4 minutes to be able to power on again, trying before that time results in the "you need to charge me" indicator on the screen. Apple support wants me to restore, which is a miserable pain because I have a number of two factor apps setup and nothing ever restores just right anymore. So, anyone seeing this on their 7?
