iPhone overheats during game play
This might be a dumb question but:
I recently downloaded Magic: Duels for my iPhone 6 Plus. About 2 hours into it the phone locked on the "Overheated" screen, which is cool, looking at the app reviews this seems to be a known issue. But I want to keep playing the game, so my question is: would that do any sort of permanent damage to the phone? Or should I just delete the game and forget about it until it gets fixed. To be perfectly honest I also had the phone plugged in to charge and I wonder if that contributed to the heat since I've noticed that charging the phone generates some heat when I use the phone simultaneously for streaming.
Thoughts?
