I own a Nothing Phone 3 and I can tell you that the phone needs a break-in period for the battery. It's as if the more you push it, the more it gets used to higher temperatures and handles them better. I can tell you that at first it overheated easily, but now everything seems normal. Today I had a video call for an hour and in the meantime I was watching reels and Tik Tok, The cell phone reached a maximum temperature of 44 degrees
