I never said people can't share their experience. And yes, if a phone is uncomfortably hot to hold, that shouldn't be. The use of the word "overheating" is somewhat abused though. A phone is overheating if its operating temperature exceeds the level Apple has determined is within normal range and if a phone does that, it is designed to put a warning on the screen, with a temperature symbol and the phone will be unusable until it cools down. If that's not happening to people, their phone may be running warmer than they are accustomed to, but it is not overheating.
For anyone who is concerned about their phone, complaining here is really not going to help them. We are all users on this user to user only forum and Apple doesn't actively participate here. So they should take their phone to Apple and have it tested. And if their phone is found to be defective, Apple will replace it. Doesn't make more sense to get ones phone tested, as opposed to being a "me too" poster on a forum of just other users? I can certainly if either our 15 Pro or 15 Pro Max had any heating issues, I'd be visiting my Apple Store Genius Bar. Fortunately, neither of our phones had any heating issues out of the box.
