iPhone 15 overheating

Hi everyone. I’ve recently purchased the new iPhone 15 pro max and it is heating up even when I’m not using it.

I was wondering if anyone else is having this issue or if it maybe a setting that is causing it that I can turn off?

Any advice is appreciated. :)

For all of you:


Do a simple Forced Restart on your new iPhone by:


  • Press and quickly release the volume up button
  • Then immediately press and quickly release the volume down button
  • Then immediately press and KEEP HOLDING the side power button and KEEP HOLDING it past the swipe to shut down and KEEP HOLDING it until the Apple Logo appears, then let go


Sign back in with your passcode when the phone prompt you and let the phone settle down over the next couple days. If you transferred a LOT of data, it can days for the indexing process to complete. There is likely NOTHING wrong with your phones.

That’s a great result! I am glad for you. Maybe per Following along may help me.

i am wondering what options those of us that don’t have physical Apple stores have? We only have resellers here and I bought the 15PM direct:


given that the 11PM I “upgraded” from was doing this exact heating up issues (leaves your hand feeling radiated for hours after it gets THAT hot) I can’t believe this is the case also with a brand new phone. Apple support even suggested buying a new phone when I mentioned my other was having this issue. It was otherwise in great condition. But could function as a cooktop…


With the new phone, I’ve tried draining the battery, updating the software, closing all aps, turning off background refresh, you name it.


I feel that this is a very expensive mistake and helpless in this case


I would love some guidance
