So while doing nothing intensive except listening to music, my iPhone 7 (edit: 256 GB AT&T) started overheating. And I don't mean it felt warm, it was starting to hurt my skin just holding the device. I couldn't figure out what caused it to happen, but I shut it down, let it cool down, and restarted it. I checked the battery section, and saw that the camera (for being in use for a minute) had a 15% impact on the battery in the past 24 hours, causing my battery to drop from 95% to 81% in the 10 minutes I noticed the overheat and had to restart. The restart seemed to have solved the problem. What I did not get however, is that I did not use the camera in that time. The only thing that I did (besides music) was use the Messages app to pick out a picture to send. But in iOS 10, that feature makes it so that the camera activates in that tiny screen where your keyboard would be. (Which is an annoying feature, anyone know how to turn it off?). My guess is that something went wrong with that, maybe causing the camera to stay on? Has anyone else noticed any overheating issues? Edit: To clarify, this is separate from the processor intensive restore process. Also not when iOS Photos app is scanning pictures when it's on lock screen and connected to power. The issue so far hasn't been replicated. On my end, it appears that the restart so far has fixed it. But I'm being cautious here since there isn't really enough time since that overheating event and now to really tell.
