So I put my phone on the charger in the middle of night around four something in the morning EST. I woke up with the sun shining through my window directly on my phone but I paid that no attention at first. I picked my phone up to check the time and it was scorching hot, so I immediately unplugged it and went back to sleep. The battery was at 68%. I woke up forty minutes later and the phone was still hot and that's when I noticed that it was directly in the sun. So I cut it off and put it under one of my pillows away from the "sun" and boom. It was back to normal when I cut it on.
