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 just upgraded 4 phones in our family to Apple 15 Pro-max. When I charge it using a wall power socket the phone gets very hot and the i-phone turns the charging off, so it never gets to full charge but only about 75/80%. There is certainly a BIG problem with charging/power management, hardware or software both. Apple is playing a deceitful game here by not acknowledging the problem and acting as if all were fine. This problem must be addressed by Apple because denial or lies or blaming customer will not solve it. The problem is less severe when charging from a laptop socket. I did not have any such issue when charging my prior i-phone.

Are the iPhones on display at the Apple Store "indexing all the new data?" They're in demo mode. I just went to the Apple Store near me to buy a new 15 Pro Max. I held every 15 Pro Max on display. They were all very hot. Sadly, I did not buy one. I really wanted to but not until they fix the issue. Please correct me if any of my assumptions are incorrect. Thank you.

This is honestly the most odd thing i have heard about optimised battery charging today :/
If you have used Apple products, you would know OBC has a separate notification, and this is coming for me even when OBC is off :(

Even when OBC is off, your phone stops charging, but instead of at 80%, it's at 100%. It then lets the battery cool and drain slightly. Again, that warning does not mean your phone is overheating. If your phone was overheating, you'd get a big error message on the screen telling you it was overheating and shutting down.

This new iphone 15 promax is hot while it charges. Only iphone we possess that this has occurred with...But it charges relatively quickly and has not shut down as yet.

That would make sense, especially if you are fast charging the phone. The faster you feed power to a battery, the warmer it gets. It's physics.

My Overheating issue is back and my Amazon Music app is again crashing within a minute because of the overheating or the app is still not optimized?

When you say the phone is "overheating", do you mean that you get the warning on the screen that the phone is too hot and it's going to shut down? Or do you mean something else. If you mean something else, please be specific about what is happening, what error messages you're seeing and how you are diagnosing this as overheating.


Does the phone overheat if you delete the Amazon Music app?

Got mine this months, overheated when setting up then warm at times. But the battery drain is stunning. Worse than my 2020 SE with 85% health! Each time I grab it drops 2 percent. No instagram no Uber no Facebook. Also people cannot seriously believe that just because it is titanium it should get warmer ot it can handle it. Any heat in any electronic phone, above 25C is bad for the electronics and especially the lithium ion battery. Heat kills batteries to begin with.
