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.

I also purchased one in late Oct and exchanged it the next day for another iPhone 15 because it overheated while it was charging, thinking that it must just a faulty battery. But this other one has been also getting pretty warm to hot over the past two months especially when being charged. It's more than likely that there's faulty wiring in these new IPHONE model.

There is no evidence of any throttling or reducing performance. A few years ago a group including ArsTechnica myself etc engaged Apple and Mr Cook agreed to the battery issue and full universal free swap for a year I think. Back then we had a clear code evidence of throttling. In the present situation the 15 processors work as intended. Also a reminder that a more efficient cooling frame will be warmer as it evacuates more heat. The hardware in the 15 Pro is extraordinary in terms of performance and a 120 Hz screen . If indeed the phone was overheating versus design you would have clear rapid battery health issue with the State of Health and State of Charge. Also anyone loving an in-line 6 S M Performance BMW knows that it is way hotter than an inline 4 but as intended. So unless noticing major battery health issues, sudden shutdowns, erratic behavior and freezing, the hardware performs as intended.

Yes my iPhone 15 pro less than two months old overheated today after I put it in my cars wireless charging pad it only was on there about 15 min and it gave me the overheating message

What was the specific message? Did it say it was going to stop charging until the battery cooled? If so, that does not mean the phone was overheating. It just means that optimized battery charging was letting you know it was doing its job.


If, on the other hand, the phone said that it was going to shut down, that means it was overheating.
