My iPhone 15 is overheating after last 2 updates

during the overheating in the back of the phone, there is not any indication that the battery is the cause. Also the photo app crashes. No one and Apple support are at the store can figure out the problem. Though I see it is has been an issue in the past. And I actually purchased a new phone because they couldn’t figure out what was wrong with my 13. So I’m out 900 and some dollars with the same problem on a new phone.
