iPhone 15 overheating during FaceTime and video playback while charging

When using the phone, if it overheats, you will get a screen warning and the phone will shut down. It doesn't seem like that or you would have mentioned it. I'm guessing the phone is just feeling hot. When using intensive processing apps such as FaceTime, or you are charging the battery, or watching video. Those are the 3 things that can make the iPhone hot. Charging the battery and the phone getting warm/hot is normal since charging the battery is a chemical reaction. Watching video or using FaceTime uses high process as well as using the camera which will make the phone warm. Unless the screen shuts down, it is just getting warm and nothing to worry about.
