Ok this is going to sound stupid. It actually is but it got me thinking. We all know that heat hurts our batteries. Today I was looking at a video on YouTube and after about 10 minutes I notice my iPhone 7 was a littler warmer than usual. Not sure if its because I was looking at the video from the pocket app and not the YouTube app but whatever it got hotter than normal. Being the maniac I am when it comes to this phone I stopped put it by the air vent and it cooled down. Now when they say heat is the killer of these batteries do you guys think they mean heat like leaving it in your car or heat the phone it self produces like from heavy use, videos, games, etc? It was like a 10 min video so I dont think I did any damage per say but this got me thinking. So what do you do when you feel your device get hot? My wife streams Pandora for hours, watches video and has a really care free iPhone experience. Heck we typically switch these bad boys out every year so is there really a need to worry so much? Have you guys notice the iPhone 7 getting warmer/hotter than the previous versions?
