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.

There are different kind of people … who loves to solve problems and play with new tech, who prefers something stable that’s working perfectly, and who loves beta software. The first like me change iphone every year it’s an hobby I enjoy myself, people like you shouldn’t preorder but wait a month or so when the main problems are already fixed…and there’s people that love betas and want the OS before it gets released having fun messing up the phone…

You are simply wrong. I have two of them. They DON'T overheat. I now know several people with an iPhone 15 Pro. Not one of them is having any heating issues. If they were ALL overheating, why doesn't mine or the people I know NOT overheating? Until you've personally evaluated every unit of the Millions upon Millions of them in users hands, you cannot validate your claim, which is simply, utterly, completely wrong. I get you're not happy. But DON'T make claims you have absolutely NO data to backup.

For all this I returned my iPhone 15 pro and my decision is to wait if they are able to solve the problem without lowering the performance of the chip, but my feeling is they are going to solve the problem in the production of new batches from now on, and unfortunately the affected devices what has been produced so far will remain as it is without much option for improvement.

Bug or not in iOS or a faulty app are non-factors. A bug may regress in a future fix, app may not stumble on this bug but another resulting in a likewise heat issue. no hardware is to overheat when stressed on handheld devices.

That's a noble, but completely uninformed statement. Any battery when pushed hard, will generate heat. As I said before to you, when you create a battery which cannot generate heat when pushed hard, you'll win the Nobel Prize for Engineering. I look forward to you doing just that. Not understanding the science of batteries however, is not an excuse for making assumptive statements, which aren't true.
