iPhone 15 overheating during FaceTime and charging

I’ve had my iPhone for over a year, most of the community questions I see about it they only have the issue for the first two weeks of getting the phone. My phone constantly overheats over the littlest things and it’s only getting worse. A simple FaceTime will have my phone almost ready to blow up. And now charging has become an issue, too. I put it on the charger and the temperature skyrockets. God forbid I FaceTime and charge at the same time and now it’s almost melting in my hand. Any normal thing I do on my phone causes it to heat up insanely and the only way to bring it down is to unplug it, turn it off, close all apps, and put a bag of ice on top of it. What on earth do I even do about this? I’m not the only one with this problem with the 15 either as I have family and friends with the same phone who experience the same thing. It’s not exactly like I can drop another thousand on a phone either.
