It definitely should not be doing that. Have you tried rebooting the phone?

not sure if this counts as a reboot, but it has turned itself off twice after the temperature warnings. I was not even doing anything heavy.(just watching videos that I shot earlier in the day)

I read that Apple "will probably" correct this with a new update within the next few days.... hope it will cure this issue.
 
I don't get why they went with glass on the backs. Looks nice but not very functional. I prefer an aluminum matte finish back.
metal would not have wireless charging i think. Thats the reason for glass.

My 16PM got very hot while recording 4K 240, back case was 47°C
117 degrees F is hot. Found this article and it seems Apple says it's normal and designed to transfer heat to the frame. Last year it was a design flaw, this year it's a thermal feature. LoL

 
  • LOW HEAT
  • HIGH PERFORMANCE
  • LONG BATTERY LIFE
You can only PICK TWO.

  1. Low Heat + High Performance: This combination usually results in shorter battery life because high performance components tend to consume more power and generate more heat.
  2. Low Heat + Long Battery Life: This combination often means sacrificing high performance, as lower power consumption components are used to extend battery life and reduce heat.
  3. High Performance + Long Battery Life: This combination usually results in higher heat generation, as powerful components consume more power and generate more heat.
 
My 16 pro max warms up a little but nowhere near as much as the 15 PM. Just did a text snapping 40 48mp ProRAW in a row and it got mildly warm. My 15 would be sizzling. And the dissipation of that warmth is faster

Helpful information here. Thanks

There's a forum member that posted 117 degrees F when shooting 4K 240 on his 16PM.. Sounds hot to me. Heat doesn't just disappear it is transferred to cooler material around it. In this case the substructure and outer frame. When you have chips with this kind of performance confined in a small package it's going to get hot. The question is how long it takes for the 15PM to throttle and dim screen vs. the 16PM on the same workload. They will both get to that point regardless, I'd like to see how much of a difference Apples thermal changes actually make

the 16pm only goes up to 120 fps? Hard to tell with a report of one. I've recorded a bunch of 4k120 without anything more than slightly warm. And anecdotally, took a ton of shots outside on a 78 degree day and I didn't get any dimming on the 16PM. Will be somewhere tropical next week, let's see.

I actually found one comparison of thermal performance and although both phones got very hot, the 16PM was able to deliver higher frame rates for a substantially longer period of time than the 15PM. I'd say the thermal improvements are working well as far as extending the performance before throttling is necessary.
 
If you want to see how hot the phone can get in extreme cases, download Genshin Impact and set everything to max graphics @ 120fps… and boy it gets REALLY HOT although the game runs very smoothly.

This is the only time I’ve managed to get it this hot. Filming 4K120, restoring iCloud stuff, or something like that just made the phone quite warm.
 
Today I used Google Map for the first time on my iphone 16 PM ( for a short 20 min drive) and it was hot. I noticed that brightness was at max level. I don't have a case yet and was driving in Dallas without AC, 86 degree. I don't remember my old iPhone 14 PM was this hot using Google map. it might be that I was using a case on iphone 14 and did not directly touch the phone.

Should I have it replaced? Is your iphone 16 PM hot when using Google Map?
 
My 16 Pro Max definitely seems to run a bit warm compared to my iPhone 14 Pro Max. It’s definitely noticeable especially sitting outside here in Texas. My 14 Pro Max never got warm. I guess this is a thing starting with the 15 Pro Max? It is definitely noticeable, but it seems to really only get warmer if I’m sitting outside.
See my post above... I had exactly the same situation as you (Texas, iphone 14PM, outside, etc)
 
How is the heat for those out there for the 16P and PM. Saw mixed stuff on youtube. Did apple fix the heating from the 15 )being super warm and to temperature shutdowns for some).
 
If the heat dissipation is better in the new iPhone, shouldn’t it feel even hotter? Isn’t heat dissipation about efficiently pulling heat away from the components producing the heat (chip/battery/screen) so that they can function at full capacity (no throttling and dimming)? And that heat would end up being radiated by the phone casing which would feel hot to the touch. If the goal is just to feel less heat on your hand, then Apple could have just insulated the heat, but that would have destroyed component longevity. The only other way is to decrease performance and/or make the hardware/software more efficient. But heat that is created can’t just disappear.

Incorrect, as general dissipation is improved, the components stay cooler, more heat is moving into the ambient surroundings, therefore phone staying cooler and you feel the cooler phone. The heat is moved into the surrounding air, which is the entire point.

You might be thinking of something more along the lines of evaporation. a large amount of energy is required to evaporate for example water, so that is why evaporating water feels cold. Not really the same thing conduction and convection on the phone.
 
Currently on a tropical vacation. My 16PM is infinitely better at heat management than my 15PM. It does get warm but that heat doesn’t stay for long. I FaceTimed from my balcony for 20 min without it being warm; that would have boiled my 15PM last year

The article linked by BugeyeSTI explains it:
Basically, no matter how heat dissipation is improved inside the phone, the heat needs to escape outside the phone to the surrounding air which it can only do by going through the phone casing. So if heat is pulled away from the processor/etc more efficiently, it will improve performance but will result in the user feeling more heat on their hand. Because the iPhone uses the casing for heat dissipation, the only way to for the user to feel less heat is to insulate the phone (which is bad for the phone and performance), or for the processor/etc. to generate less heat in the first place.

Interesting article... No wonder I felt iphone 16PM (naked) hotter than iphone 14PM. However, many people, like myself, use iphone with case. This would defeat or slow down the effectiveness of iphone 16PM dissipating heat to outside.

Yeah a case does insulate and slow down overall heat dissipation, especially material like silicone. But a case, even one made of silicone, also has a lot of material and that material can probably absorb a nontrivial amount of heat (albeit slowly), which might make it ok for a limited period of heavy processing before it starts to trap too much heat inside the phone. But I believe there are also cases designed for heat dissipation—namely perforated and made of heat-conducting material.
 
Wonder if it is because Airdrop is on for everyone vs contacts only. I will toggle that off and see it that is the cause… might explain the battery drain. I do not recall ever setting it to everyone.
