Apple Says iPhone 15 Pro's Titanium Frame Does Not Contribute to Overheating Issue

It’s actually funny because since iOS 17 was dropped I’ve been waiting for apps like Instagram and Uber to update and adapt to iOS 17 but they have not dropped any updates.

A lot of apps actually didn’t update the week of released which is odd because usually on iOS release day there is a glut of app updates and this year there was barely any.

So I completely buy what Apple is sharing here.

I mean... dissipation from where? If we're just talking about getting heat from the SoC to the frame, then yes, aluminum conducts heat better and should work better than steel, all else being equal. But most of the heat is dissipated into the environment via the frame, which will be a function mainly of the frame material. So the phone could still be better at dissipating heat from the SoC while being worse at dumping that heat into the environment.

That said, I'm going to give the hardware engineers the benefit of the doubt for now, and I'm inclined to believe Apple when they say that rogue apps are contributing to the issue. And in any event, I would rather deal with an occasionally warm phone than have the performance throttled. But that's me.

Apple today said it plans to release an iOS 17 software update with a bug fix for the iPhone 15 Pro and iPhone 15 Pro Max overheating issue, and the company has since shared additional details about the matter with MacRumors.

Importantly, Apple said the issue is not related to the titanium frame. Contrary to a report this week, Apple said the iPhone 15 Pro's design does not contribute to overheating. In fact, Apple said the titanium frame and aluminum substructure provide better heat dissipation than any previous-generation Pro models with stainless steel frames.

Apple said some third-party apps have overloaded the A17 Pro chip for unknown reasons, including Instagram, Uber, and racing game Asphalt 9: Legends, and it is working with the developers of these apps to address the matter. 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.

To reiterate Apple's statement:More details are available in our initial coverage of Apple's statement.

Games with great graphics I understand that could overload the processor.
But Instagram, Uber? What kind of massive processing are these apps doing to overload the processor? Could it be something we should worry about?

Titanium somehow being hotter than other their metals was always an obvious misunderstanding of physics. Sure, aluminum has a lower specific heat, but all that means is that it doesn’t take much to get hot and it doesn’t take much to cool off. Besides, the phone is still aluminum on the inside.

Imagine making a phone today with the power of an Xs but with 3day battery life. Chasing performance is no longer attractive at these levels - battery should be the differentiator

Thanks Apple, but the issue started after 16.5.1 update and isn't isolated to the 15 Pro Max. 13 and 14 pro maxes are also affected. And let's not forget about the battery.

They don't do massing processing, but it isn't about that. It's about bugs. A very simple app can overload the phone with a bug that keeps CPU at 100%.

It’s because the frame isn’t actually titanium. It is aluminum with a thin titanium facade.

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 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...

You guys need to go back and watch his first video where he tears the 15 Pro Max apart, in that video he cuts a cross section of the frame and you can see the intersection of the aluminum and titanium. It’s easy to see there that Aluminum makes up a good part of the frame. That’s where Apple’s done the bonding of the two metals. The AL part just melted away in the second video leaving just the very outer titanium parts, and you can tell what is left is thinner than what he started with in the second video too, plus the buttons and USB-C port ring.

That aluminum part is on the INSIDE of the phone, not on the outside. It is exactly what Apple said it was. They said they bonded aluminum to the titanium, but the entire aluminum part is on the inside. The entire outside, except the antenna coating, is grade 5 titanium. Watch his latest video where he puts it into a furnace to melt away the aluminum. I saw the one you’re referring to and it showed exactly what Apple said it would be. Apple put more titanium into the phone than JerryRigEverything thought. Even the buttons are grade 5 titanium.

If it were a veneer, like so many people are saying here, the entire frame would have collapsed with no real shape because veneer can’t hold its shape. The entire outer frame is titanium.

How is the iPhone 15 Pro/Pro Max overheating not a hardware issue? It's the A17 Pro chip that's generating the heat, is it not? If the A17 Pro chip is not hardware, then what is it? It's certainly not software.

It happens with A16 too. Its all combination of iOS 17 + Zucc
 
Far from a scientist but riddle me this. For those who claim the 15PM overheating issues are indeed due to the design/ titanium etc, then why are people with older devices (14PMs and before) all of whom installed iOS 17 are also reporting their devices getting extremely hot ?
 
honestly in benchmark testing today with my 15 pro against other devices I have, the metal case of the iPad Mini 6, iPhone 7, and iphone 5S got MUCH hotter than my 15 pro.

Could part of the issue be many new users running without a case this year than before?

I have had the 256GB iPhone 15 Pro Max since September 22nd and I have never experienced any overheating issues, during setup or when fast charging or playing other games. During 22w fast charging my phone barely gets warm. Not saying that people aren’t having issues just saying I have not had issues. I also don’t use Uber or Instagram or Asphalt 9. So the issue is either hardware related and I don’t have impacted hardware or it is a combination of installed apps that is causing the issue.
Oh, the phone also doesn’t get hot during Geekbench 6 single or multicore tests. It barely gets warm during those tests.
