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.

No, it's like a healthy person in the city stating, "because I'm not sick then no one in the hospital is sick either."


The narrative of "Not everyone has this problem" or "only the people that have this problem are complaining about it" is extremely weak.


The question now is what is going to be done about it.


Are they going to reduce the temperature at which the A17 Bionic slows its clock speed to reduce power consumption and heat? Are they going to modify the thermal solution on future production? Are they going to change the binning process of the A17 Bionic to use only the lower-power production on the iPhone and save the higher-power production for future iPads? The answer should be known within a few weeks.

lobsterghost1 – I'm curious, when you say that you're having no heating issues, does that mean that you're having no heat under normal usage at all, or that the heat that you're having is within your tolerance?


I'm torn on mine -- I haven't had it get *very* hot again like it did the other day, but it is still getting noticeably warm when performing tasks that shouldn't cause it to heat up. For example, just from browsing the web (this page and a few others) on Safari just now, it is now noticeably warm. I have never had a previous phone get warm just from browsing before.


Is it within the realm that it's dangerous to the phone? No. But is it something that I'd consider "normal"? No, not that either. It's not burning me or anything, but it's honestly not particularly comfortable to hold.


So... do I wait around, and hope that Apple issues a fix (that doesn't just throttle the heck out of the processor)? Go ahead and return it?


The reason that I'm curious about your experience though... Due to a double-ordering issue (for some reason my first order got marked for shipping rather than store pickup, so I tried to cancel that and re-order but they messed up the cancellation and shipped), I've actually got a second identical phone here in a box that I'm intending to return as soon as I have time to run to the Apple Store (probably this weekend). But now I'm wondering... Should I open it, try it, and see if it's better? I'm a little hesitant because I don't know how opened vs. unopened affects the return. But if it's possible that I've got a better working phone just sitting here...

It's always better to wait a while before purchasing a complex new product. Inevitably there are minor design and manufacturing changes to address issues that are not discovered in pre-release testing. The old adage of "never purchase the first model year of a new vehicle design" applies for other products, though with a shorter time frame, i.e. "never purchase a new phone the first six months after it is released."

I just got off the phone with Apple Support. They said my support call about the 15 Pro overheating when charging with a magsafe charger was the very first call that Apple Support has received for this issue... hmm. Anyway, they said this is normal behavior for a new iPhone to get hot and stop charging when using a wireless charger and that if the issue is still occurring in another week, to call them back.

How is this acceptable support? Referring us to help forums that we’ve already tried is not helpful. Apple needs to do something on its end. I’m not that loyal to their products so chop chop or get the chop apple and lose your core (base). Not going to thank you yet when you’ve done nothing.

This is a user-to-user forum. It is not Apple Support. And Apple isn't reading here for feedback, suggestions or demands.


If you want to discuss that matter with Apple, use the Support like at the bottom left of every page of these forums.

I have tried that. Uninstalled instagram but problem still persist. Tried hard rest, still no luck. Tried all workarounds as suggested by others, no luck. For me the heating is only when I am on a call. gets SUPER hot within 10-15 mins and then battery drains significantly (~1% for every minute) General browsing, watching videos/YouTube no issues at all.. I know others have reported issues when charging too but that's not the case for me. Charges all good & no overheating issues. It's just the calls for me...

I agree, suppose you have just bought the iphone, and you are setting it from a backup, d/l a number of apps, millions photos, documents, and in settings everything is enabled, and you immediately try to shoot a 30 minutes 4k video at 60fps, watch you tube for an hour or play games for another hour...while charging it, I think you could do scrambled eggs on top with a slice of bacon without having a faulty iphone

I don't this so. Just because some of you aren't having the issue doesn't mean there isn't one. A lot if us here have given this time. And a lot of us here aren't 1st time iPhone users. I myself have been using iPhone since series 4 and have upgraded every 2-3 years. We know how much time to give for initial setups/indexing. We are here because after all this we are still facing the issue and Apple hasn't been helpful in answering.. A basic task or a phone call for 15 mins should not overheat the phone to this extent and take up so much charge. There is some serious flaw with this new phone and it's affecting many many users. Period.

Unfortunately that’s what a lot of folks seem to be doing. Excitement with possessing a brand new device.


  • Connect new phone to old and start sync process.
  • When complete disconnect link.
  • Without realizing that background tasks (indexing, cloud shared photos etc.) are still running, promptly check out new features of an amazing phone - Hi-Res videos, Raw photos, games, share them to friends via social media, make calls etc.
  • Observe phone gets warm (more so with the titanium band), read these posts on forums and news sites and freak out.


Problem is they don’t know how long the end to end process takes and there is no update/migration status feature telling them when it’s done.

Please stop posting these comments telling everyone that nothing is wrong. You cannot be certain that all of these comments are not due to something serious occurring within the phone. I do know that titanium retains heat much better than steel or aluminum so I wonder if that titanium outer shell is trapping more heat than it should?

When you buy the forum, you can tell me and anyone else what they can post. I NEVER said nothing is wrong. I'm sure for some users there is. But in reading all these oh dear, the sky is falling posts, I'm willing to bet for many, nothing is wrong. Instead of psoting oh dear, the sky is falling to other posters on a public forum, which Apple doesn't even participate, anyone who believes their phone is not performing as expected, they should take the phone to the Genius Bar at their Apple Store and have it tested.


Whether the Titanium case is causing an issue, I can't answer. I'm not a thermal scientist. I'm sure Apple did a lot of testing before deciding to wrap the phone in a new metal. And there are people who have reported heating issues on non-Pro models. They're wrapped in aluminum as they have been for years now. So, I kind of doubt the metal makes that much difference.


Again, I NEVER suggested no one has a problem. But if they do, posting here about it is about a useful as shouting into the wind. Let Apple test the phone.

Yes, I reset without restoring a backup. I uploaded everything again. After 2 days, the battery seems to have stabilized a bit, but it's still not what I expected from a $1,200 phone. The phone heats up much more than its previous versions, it does not need diagnostics in the store, because you can feel it and see it on the thermometer. I still have a few days to return it, so I'm testing it. However, when I read some opinions here that there is no problem, I feel discouraged, because on the hotline they admitted that they had already had a lot of calls like mine.
