iPhone 13 Pro overheating since the last update

My 13Pro is randomly overheating while charging with zero apps open in a cool environment, not streaming etc. just charging. It started doing this overheating thing about 2-3 weeks ago very soon after the iOS16 update. It has never had any overheating issues before. The battery seems to be draining exceptionally fast as well but I'm not charging it any more then I ever did really. Powering the phone off will almost immediately cool it down. But removing it from the charger does not particularly cool it down without powering it off. It doesn't happen all the time but when it does I get the error message that charging has stopped while the phone cools down as if it has been sitting in the sun for 3 hours. Any advice? Closest Apple store is 1.5 hrs away.
