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.

Okay, just to say and maybe to calm a few people down. I picked up my iPhone 15 Pro Max 2 days ago and so far I can say that I had zero issues with it. I transferred all my data including all 324 apps from my old phone to this one and I didn´t noticed any kind of "extra" heat, it was normal. I also charged it the whole night using Magsafe and in the morning, no heat at all.


I also tried normal surf and a game. Nothing at all so far.

But I will of course try some other stuff, demanding apps and though games and so on.


The issues people say here might be related to some countries or something else, I really don´t know. I live in Sweden! Just wanted to say this so people don´t think the heating issue has do do with every phone out there.

I think it's even useless to reply, they didn't chat or call the support, they didn't test the iphone, they didn't measure the temperature and they didn't get any message on the iphone for overheating, so in my opinion all this doesn't count unless they head to an Apple store. BTW my iphone 15 pro 256GB is just great I love it, it's much better than the iphone 14 pro I had and it's not overheating at all.

please for all those who want to be the apple advocates doubting what millions are going through. You can do that outside this community where all the Samsung users are waiting to troll! The phones are overheating and the least you can do is downplay that!

When you buy the forum, you can dictate who can post what. Until then, why wouldn't people who don't have an issue be welcome to post? Is there some rule we have all missed which suggests only those with an issue can post? Or do you not think someone who comes here, might appreciate knowing not every iPhone 15 out there has a heat issue?


Finally, can you please validate the claim that "millions" of people are experiencing this? I thought so. You simply can't. I could do the same and ask you to not make claims you cannot backup without evidence.

Hi. My wife and I each bought the iPhone 15 Pro Max 256gb models. The iPhone's here is South Africa have 1 physical sim and 1 e-sim. Thus far we had no heat issues during the setup or now after setup with normal use. Temp is normal like our iPhones 13 Pro Max. Battery live is same as (well ok...actually slightly better) than our previous iPhone 13 Pro Max's. Because of all the overheating reports, we were in doubt whether we should upgrade before the iPhones were released here but decided to "take a change". Glad we did. Hope Apple can quickly solve the heat issues for the folks having it.

Iphone 15 pro 256 GB blue here it’s quite a piece of technology I love it, it’s just awesome, lighter than my iphone 14 pro, the shape is really nice, it’s working perfectly, no overheating or strange warming up. Everything is fine. I do not use any of the apps pointed out by Apple. I don’t like Android os. I left them for Apple many years ago, not going back
