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.

Same here. And it’s really upsetting. I waited so long for this phone. I wanted to upgrade my old one 6 months ago but I told myself if I waited I could get this one because it’s supposed to be amazing. I’m deeply concerned that I just paid a small fortune for a phone that could double as an electric stove top because it gets sooo hot. I have to keep the brightness down to its minimum and it hardly helps, in the time it took me to write this it’s already almost too hot to handle. I really really hope they fix this issue because otherwise, I’m going to return it and go with Samsung. I’ve been an apple user since smart phones first came out but I can’t justify the price of this phone if it’s not going to operate properly. Sad Face

iPhone 15 Pro Max has been getting extremely hot while using it normally and especially while charging it. Having to charge it multiple times a day. The phone also arrived with scuff/discolouration-looking issues with it as well, and the silicone case I bought for it is misaligned. Very upset and disappointed in Apple... I called customer support and spoke to several different people (over 1.5 hours) - no one proposed any helpful solution other than to wait until November-ish for a new phone to come in stock... they wanted me to return the only phone I have from them in the interim, even though I run my business off of this phone! What an awful experience....

My iPhone 15 Pro stops charging when connected to CarPlay. It’s uncomfortable to hold when texting and listening to music. When it gets this hot, I can watch the battery life % drop each minute. I upgraded from 13 Pro because of poor battery life. Then to 14 Pro in hopes of an improvement. Now the 15 Pro is the worst of them all. Why is Apple making their new worse than their old ones?

I’m having the same problem. Phone is getting really hot. I’m not using a case and notice it right away when using the camera. Was outside testing out the camera for about 10 min in 20 Celsius weather and it was uncomfortably hot in hand and in pocket. Seriously considering returning my phone. This is not a problem I’m ok with in a phone at this price point.

My iPhone 15 Pro's battery is going haywire! There's no background stuff happening, and it's not getting too hot, but the battery's still dropping like crazy even when I'm not using it. Left it at 89% last night and woke up to a 78% this morning. I didn't even set an alarm to snoop on what's causing this, but in just 7 hours of chill time, it lost a bunch without me even touching it. What's up with that? Also, it's not getting as hot while charging anymore.

Well, this was NOT fun to hear and read.

I live in Sweden and have ordered a new iPhone 15 Pro Max that should come around October 18. But after everything I read and saw on YouTube about this overheating issues, I think I will not buy it, at least not until we know if it´s a software issues that Apple can fix, or if it´s a hardware issue that can´t be fixed. Then it´s better to keep my 14 Pro Max, that phone never gets hot for me!

Thanks for answers, helpful indeed!

It´s VERY scary to buy one now. The phone hasn´t started to burn like Samsung did, but it´s dangerous close.

My 14 Pro Max never get anywhere close to hot if I´m not in the sun!

It´s odd that a factory reset would help you gigimotown, but glad it did for you!

I do hope that Apple read threads like this and also knows about it. VERY odd that they didn´t find out during the manufacturing process...

Anyway, I keep my 14 Pro Max and hold the 15 back a while, at least until I hear any news from Apple about this.
