One day I was playing games on my iphone for about 30 minutes straight. I have an otterbox case for it so after a while it felt hot. I took the case off and DANG it was extremely hot. The steel covering for the iphone was hot and the back was even more hot. I powered off my iphone and after 10 minutes of sitting on carpet it got cooled. This happens all the time even after 10 minutes of usage it will get hot. Is there anyway to prevent this from happening feels like my phone is going to overheat. Does your iphone do this?
