"Apple said its bug fix will not involve reducing the chip's performance in order to address the temperature-related issue, and it ensured that long-term performance will not be impacted."
Just because “Apple said” it doesn’t mean it’s true. Apple said a lot of things in the past, e.g. #Batterygate, yeah “Apple said they didn’t throttle”, well at the end it turned to “Apple lied”.
 
They are in denial of the fact that their software dev team is run by idiots.
They destroyed the ecosystem over the years. macOS and iOS have more bugs than apps.
They had the most solid os ever and they screwed it.
Bring back Bertrand Serlet and Scott Forstall please!!!!

I don't think macOS has ever been as stable as Sonoma is for me, and I've been running it since Lion. iOS is also pretty great considering everything it is doing and the massive number of 3rd party apps.

But sure, think it's run by idiots. Forum experts strike again!
 
No, material wise it’s worse…

Titanium thermal conductivity λ=15.24W/(m. K), about 1/4 nickel, iron 1/5, aluminum 1/14, and a variety of titanium alloy thermal conductivity than the thermal conductivity of titanium decreased by about 50%.

The thermal conductivity of stainless-steel ranges between 20-60 W/(m.K). Generally speaking, stainless steel has higher thermal conductivity than titanium and is thus more suitable for applications that require heat transfer or rapid cooling.

Classic Apple defending themselves again of course it’s a hardware issue and titanium is that issue
Education is your friend. Study up.

Note as you proceed in your studies that all Titanium and stainless steel product implementations are alloys, of which there are many with differing properties. Referencing Titanium or stainless steel as a single thing expresses ignorance.

Glad they’re jumping on this. Did no one test these apps before release?
I'm not claiming to be objectively correct here, but it's possible that some of these issues were caused by the iOS 17 compatible updates to these apps, which weren't allowed to come out until the day iOS 17 came out. iOS 17 only came out 4 days before the iPhone 15, so they wouldn't have had a long time to discover and investigate these issues.

I don’t think its the Titanium frame, but bear in mind that the frame is not pure Titanium, its not an alloy either but closer to Aluminum coated with Titanium.
 
My 15 Pro Max has been fine.

Yesterday I ran the Geek Bench app on mine and ran the CPU and Compute tests right after the other, and I then ran the same tests a second time and again ran the CPU and Compute right after each other, and mine barely felt warm, if anything my 15 Pro Max felt cooler than other iPhones have when using the app. So the comment from Apple with regards to "the titanium frame and aluminium substructure provide better heat dissipation than any previous-generation Pro models with stainless steel frames" seems to have some validity in my opinion.

When my 13 Pro got hot, I felt the heat coming through the back glass and not the steel frame. The 15 Pro has been identical in my experience. (In the 2 entire times it has gotten hot so far...) Do I have bad nerves in my fingers or something? Why all this discussion of such a small part of the total area that can radiate heat?
 
Should clarify that higher numbers are better here 😅
It depends what you want. If you want something that doesn’t feel hot when you touch it, lower is better.

As in, definitely don’t make oven gloves out of copper. Make them out of silicone or something insulating.

If you want the metal frame to dissipate heat from the internals of the device then higher is better. But you’ll feel the heat.
 
So during the whole testing phase no one at Apple thought that it was a good idea to say give out a few phones to do “real world” stuff. They’d rather keeping it under secret and risk this sort of public embarrassment after offices release?
Yes. Said "public embarrassment" is largely amongst click-baiting UTubers and the silly folks who seem to enjoy the week-one sensationalizing. Then the new issues found get routinely fixed and the world goes on.

Yeah it’s not pure titanium, it’s even worse than pure titanium, it’s Ti-6Al-4V a.k.a titanium grade 5.

Wikipedia:
Ti-6Al-4V has a very low thermal conductivity at room temperature, 6.7 - 7.5 W/m·K, which contributes to its relatively poor machinability.
 
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.
Let’s think critically.

If a material conducts heat better, that means heat radiates through it at a faster rate than another material. The fact that titanium and aluminum conduct heat better means that the heat that the chip and battery in an iPhone are radiating outward, conducts through those materials better than the previous materials.

That heat therefore, moves through the titanium and back glass at a faster rate and that energy is felt in a human hand faster, and to a greater degree.

So, it may actually be helping the chip and battery inside, but you get to feel it more in your hand…

It kinda does, actually. To lie in a public statement not only needlessly erodes trust, it also opens the company up to legal liability. So there’s literally no incentive for Apple to say they’re going to release an update that doesn’t reduce performance, when they’re actually planning to reduce performance; they could just say nothing and be in a far better position.

And your example is nonsense. Apple never said they weren’t throttling older iPhones; in fact, they were open about what they were doing in the release notes. What they have always claimed is that they aren’t deliberately slowing older devices to encourage upgrades, which was and remains absolutely true.
 
Not surprised. Unless they changed the thermal design, titanium has half the thermal conductivity as stainless steel and 40 times less that aluminum. Titanium just doesn’t conduct heat well so you tend to get hot spots.
