Iphone 16 Pro overheating

Same issue here. I had to keep my phone in the refrigerator. I had take about 1,000 photographs in the burst mode in 8minutes. My friends who are Android users had a good laugh 😔

What do you mean by "log" a support call? Do you mean record the conversation?

Recording on .5 with flash only last 7-10 minutes in a slim case. Overheated in a 75 degree room. This is terrible compared to my iPhone 13 Pro Max

My iPhone 16 overheated today and set off the ADT smoke alarm.

I will return it if this happens again.

Mine is also overheated, even though I set it to flight mode and let it sleeps, and either when I use magsafe or regular charger on different charging times.

Ever since I updated to iOS 18.0.1 my overheating issue has not returned. I have used the phone the same way as before. For now, I consider this problem resolved for my phone.

i updated iOS to 18.0.1 and updated most of my applications, it became good .

Same happens to me with brand new iPhone 14. Overheats and turns off while only browsing the web.

really considering switching to android

I see that there is actually a warning about increased battery drain and higher thermal output. During initial setup, you can see this on the battery settings page. I set up my phone on Saturday, it is now 48 hours later on Monday, and this screenshot was taken just now:

might heat issues only lasted for the first hour or so after I set up the phone, very soon after the data transfer from my old phone to my new phone had completed, and the phone was installing over 120 apps. I haven’t noticed any excessive heat since those few couple of hours of setting up the phone.

I deliberately had the phone on charge the whole time, so that the phone could draw power from the charger, rather than the battery, because draining a lithium battery hard will increase the actual batteries thermal output, further compounding heat issues for the phone itself. Having the phone at 100% charge (or whatever maximum you’ve configured in the battery optimisation settings) and connected to a charger, will keep it cooler during high demand periods.

Are you charging with MagSafe or USB-C cable?

If MagSafe, are you charging with the case on, or case off?

If MagSafe charging with the case on, is your case a well-known brand, or a not-so-well-known brand?

The reason I ask: a lot of aftermarket MagSafe cases for the iPhone 16 are being sold with MagSafe coils that are NOT aligned/centred with the phone's internal MagSafe charging coil. MagSafe charging relies on accurate alignment of the case's coils with the phone's coils. When they're misaligned, not only is charging less efficient (i.e. slower), a lot more energy is given off as heat.

If your case has a transparent or semi-transparent back, you can roughly tell if it's misaligned by seeing if the Apple logo is centered in the case's MagSafe circle, or if the logo looks a bit higher than centre. Recently I bought and reviewed two aftermarket MagSafe cases for my iPhone 16 Pro, both of which had misaligned MagSafe rings. I was wondering why they were charging at kinda USB 1 amp speeds and found that as soon as I removed the case, the phone charged a lot faster.

In the photo below, I have taken a spare magnetic ring that fell out of a MagSafe battery pack, and I've let it snap into place on the back of the naked phone, as a visual indicator of the position of the phone's internal charging coils. I've then put the offending case onto the phone, and taken a photo from dead centre above.

I also confirmed separately that the Apple MagSafe puck aligns itself to the case's coils, not the phone's coils. As you can see, the case's MagSafe ring is about 3-4mm (0.12" - 0.16") too low. I believe this is a design challenge for case manufacturers that have a rugged thick frame around the camera lenses - if they put their MagSafe ring any higher, a lot of MagSafe chargers and mounts would clash with that frame. The second photo shows an example of how close my MagSafe battery pack comes to the phone's own camera structure - and this is without the case and its thick camera frame. If the case's ring was properly aligned with the phone's MagSafe coils, I reckon my battery pack would not be able to attach properly because it would hit the case's thick frame around the cameras.

The third photo is me pushing the Apple MagSafe charger puck upwards by approximately 3-4mm just to illustrate how the bottom edge of the case's camera protection frame pretty much hits the top of the MagSafe coils.

I think cheaper case manufacturers are dealing with this by simply putting the case's MagSafe coils lower. Effectively this means that such a case does not officially support MagSafe, because Apple's specs would no doubt be very exact about coil alignment as they don't want to be blamed for slow charging.

Thank you! I was trying to log the issue online and must have been in the wrong place. It just kept asking whether I had an issue with a broken screen, battery etc. No option for overheating. I’ll try a call tomorrow.

Same problem. First day with the SIM in. It was just very warm compared to to iPhone 14 Pro which was next to it not doing very much apart from streaming music to the car. The 16 pro was very warm indeed. I think there is a fault. Never had this with the 14 pro streaming music for hours long journeys in the car. I’ll use it for 2 more days before returning it if it happens again

And the same set of suggestions. Pretty much every new iPhone release is accompanied here by a spate of "overheating" complaints. After week or two we don't see many posts about it anymore. Why? The iPhone has done its set of initialization procedures and is just running normally. Why don't you see it with your iPhone 14? Maybe because the iPhone 14 is likely 2 years old.

I received my phone on 9/27/24 and initially the phone wouldn’t turn on even after charging for over 3 hours. I arranged for Apple to send me a box to investigate. I put the phone back in the original box and forgot about it. The box arrived today 9/30, and I decided to see if it would charge and turn on. To my amazement the phone finally began charging. Immediately, I noticed how hot it was. I’ve never used the phone but it’s super hot and worrisome. I read the comments about waiting but waiting too long will make the phone ineligible for return.
