When has the frame of an iPhone ever been a significant part of the heat dissipation of the phone? The times my phones have gotten hot it was always the back that was hot, never the frames.
Same here, except the front is hot on my 14Pro too. (the front and back get hot when it overheats.)

I just ran Geekbench 6 with phone plugged in to charger, and it didn’t even get warm. Also, I know there’s variability in performance but my 15 Pro Max appears to be about 15% faster than average 14 Pro CPU benchmarks, about 5% faster than the quoted 10% CPU performance gains. So even if my chip runs ever so slightly hotter to achieve slightly higher scores, I didn’t feel it at all in the phone.

I highly doubt that Apple has designed a phone that is unable to run without remaining at reasonable temperatures.

I understand that there are issues with certain devices, but it isn’t every device so that means it’s not the hardware at fault.

The Apple Watch battery drain issues, paired with this just screams “software”, and iPhones suffering will have the issue rectified. Anyone that has suffered third degree burns /s are still well within their return window.
 
What I said is if there is insufficient cooling, there would be throttling. One example is an Nvidia video card I have.

The manufacturer has software that allows you to overclock the GPU. If it gets to a certain temperature, the speed of the GPU will be throttled.

I never said the 15 Pro runs hotter than 14 Pro. Apparently Apple thinks the 15 Pro runs too hot or they would not be coming out with a fix, which will probably throttle the processor.
The assumption you have clearly made is that software won’t fix the problem. Why would they need to throttle the cpu if the app is (for example) pushing the high performance cores when there is no need, and it should be using the efficiency cores? Why would instagram need to use the high performance cores for background tasks? (As a possible example).

Which Apple apps are having an issue? I was under the impression it was only some 3rd party apps.
Phone and Camera from what I've seen. I don't use the phone that much, but the camera app definitely makes my 14Pro hot. (but it always has since I got it last year.)

So then you're not really saying anything. All CPUs and GPUs throttle under that logic, especially all phones. No phone can run at full load without throttling.

I never said the 15 Pro runs hotter than 14 Pro. Apparently Apple thinks the 15 Pro runs too hot or they would not be coming out with a fix, which will probably throttle the processor.

If the 15 Pro isn't running hotter than the 14 Pro, why would Apple be "fixing" it by throttling the processor? There's no evidence whatsoever that the 15 Pro requires extra throttling.

The issue isn't that the phone is running too hot under load, the issue is software bugs running the phone under too much load inappropriately. Does that make sense?

I really do hope there is no throttling with the investment people have made with these premium 15 versions. I also recommend constant testing after each software update to make sure people get what they were told they paid for.

The entire frame (the metal part around the phone) is titanium. Only the "substructure" (the "interior" portion of the chassis to which the components are fastened) is aluminum. This has been verified independently as well...
That is incorrect. The facade of the frame is titanium, bonded to aluminum. That has been independently verified:
 
It actually is Grade 5 titanium. JerryRigEverything just published a video where he and a friend put the entire frame into a 2000F furnace. The aluminum melted away leaving only the titanium. The entire outer frame actually is titanium, including the buttons. It’s not just a veneer. It’s the whole outer frame. Aluminum has a 1500F melting point while titanium has a 3000F melting point, hence the proof that the frame is exactly what Applle advertised it as. Grade 5 is very high grade, too. JerryRigEverything also put the frame through a spectral analysis that proved it was indeed Grade 5.
The grade of titanium isn’t what I’m talking about. I’m talking about the amount of titanium. It has been independently verified that the titanium is bonded to aluminum, and there is approximately 1 mm of titanium as a facade for the aluminum:
 
NEWS AT 9: In a world’s first breakthrough, Apple defies physics by creating a new form of Titanium that is as thermally conductive as Stainless Steel. Until Apple’s new iTit (TM) was introduced, Titanium had roughly half the thermal conductivity compared to a piece of stainless steel with the same cross sectional area.

Moreover Apple was able to achieve this physics defying feat of dissipating with titanium walls only 70% the thickness of the previous steel frame and amazingly has managed all this while using a chip 10% more power consuming than the previous model. Certain Nobel prize incoming for the material scientists that worked on this truly incredible device.


I’m a bit of a high power flashlight enthusiast and while titanium is a popular body material due to its weight / strength ratio, its hideous thermal performance means that heavy copper inserts are basically a must, offsetting much of the the weight advantage and creating a conductive mass in which to sinc and dissipate thermal energy.

If iPhone had introduced a vapour chamber I could believe that performance is similar to the prior model, but as it is, thinner walls, combined with the phone’s low overall mass and much poorer conductivity it’s clear that throttling will be more difficult to mitigate.

Instead of writing all that speculation you could have just tried out stress tests on a 15 Pro next to a 12/13/14 Pro and realised with your own hands that far more heat radiates out of the 15 Pro titanium/aluminium side rails than the older stainless steel side rails.

This is objective fact and anyone with access to the phones can replicate it themselves easily. You're just wrong.

I can’t really see how this can be anything other than a bug in iOS (or possibly the Xcode compiler) or the hardware just running too hot. There are no clockspeed APIs exposed to iOS developers; the OS (or the hardware) chooses when to reduce clock speed due to heat, its not in the control of the developer to throttle or not throttle their app.

Even if the developer is spawning tons of threads and using all the CPU and GPU resources, that shouldn’t cause overheating, the hardware should throttle back performance when the heat rises. For this to be the fault of specific apps makes no real sense to me. Maybe they’ve somehow found a way to force the hardware not to throttle back, but in that case they would be in violation of the TOS of the App Store as you’re not supposed to use undocumented API calls (I would actually be surprised if there is an API for adjusting performance though).

I just can’t see how this is the fault of the apps. I know when it comes to RAM usage iOS will force quit an app if it starts allocating too much RAM to itself too fast or using too much RAM. So again, it doesn’t make sense to me for this to be the fault of apps when Apple have had good controls for app misbehaviour for years.

There was a time when the behavior of software was controlled by the software. Today, the behavior of much software is controlled by what the server is doing. An application can be quite nice and polite when in testing phase. When it is released to the public, polling rates and such can be cranked up and the program goes feral.
Chronic problem in devops environments: Stuff works in Labs, fails in the real world. There's no scenario where even the biggest, best financed vendor could afford testing to "Street-Standards". Real intelligence and real life are vastly more complex. Pretty much everwhere you look, testing is a lofty goal, but largely an illusion. They do what they can, good days, bad days, some gems, some lemons, so it goes. The rest is covered under a license with liability waivers and indemnification clauses. Pays yo money and takes yo chances. Frankly, its a wonder anything works at all.
 
Titanium has a thermal conductivity of 21.9 W m-1 K-1 with aluminum at 235 W m-1 K-1. Stainless steel has a thermal conductivity of 15.0 W m-1 K-1.
Can't hang a conclusion on one property. One question is: To what extent was the stainless frame being interfaced with the heat source? As I understand it, the aluminum innards were/are epoxied to the frame, which makes sense because welding would warp the components beyond the tolerances to which they obviously designed. Then the question is how heat-conductive was that epoxy interface before, and how might the implementation have changed? And to what extend is the rear glass used as a heat sink? More or less now then before? Apple will never reveal that data, and reverse engineering to find out would be exhausting.

If both phones ran hot when used as intended, then both phones had insufficient cooling.

Almost any phone or computer can get hot. It's within the design tolerance so how is that insufficient cooling? Please elaborate.

It sounds like you're saying that any computing device that gets subjectively hot to the touch but well within the design tolerances has insufficient cooling. Surely you're not saying that though?
 
I just ran Geekbench 6 with phone plugged in to charger, and it didn’t even get warm. Also, I know there’s variability in performance but my 15 Pro Max appears to be about 15% faster than average 14 Pro CPU benchmarks, about 5% faster than the quoted 10% CPU performance gains.

you're comparing iPhone 14 Pro Max last year data results, here's mine just did it right now iOS 17.1 beta.

or... you know... fix bug that's causing an infinite loop or something.
Can't wait to find out. If it is an infinite loop or something, what does that say about Apple's QC before releasing the software to the public in new devices people just spent hundreds of dollars on?
