But somehow the cut didn't bend the aluminum to make it look thicker? Nice trick you've got there.
The cut wasn’t straight. If you notice in your screenshot, the entire bottom of the frame is missing from the left edge. So, yes, only the metal present, titanium, was bent at the edge.

I’ve corrected your screenshot with properly aligned, parallel lines (green and orange lines).

Yeah you changed the angle to be wrong. Whatever. Enjoy. 🤦‍♂️

Doesn't matter, the frame isn't touching the SoC, it isn't dissipating the heat (like a heatsink or vapour chamber).

I'm not going to step into the whole objective fact titanium amount thing, but I will add that this year, the aluminium/titanium/whatever side rails do actually dissipate a fair amount of heat compared to the side rails on the stainless steel phones. One of the things you will notice straight away if you are running stress tests/games/etc.

That's the funniest/saddest thing about this whole titanium frenzy, is that the parts of the phone where the titanium is are actually obviously better for heat dissipation. Goes to show, all the people claiming titanium is causing these phones to run hot don't know what they're talking about.

I agree completely. The underlying aluminum dissipates heat better than titanium, which should facilitate better heat reduction. But some don’t like that Apple bonded the titanium to aluminum. Why? The world my never know.
 
interesting that no one mentioned a Facetime call for the heating problem! what's wrong with my 15 pro?

You're holding it wrong. :p

Sorry, you left that wide open.. Too easy! 😁

BL.
 
So today I had to navigate somewhere using maps, and I did so on my wireless car charger I got off Amazon. While doing so I was on a long phone call, the phone never got hot or overheated, passed the trifecta, make use of this info as you wish.
 
side-note (as posted elsewhere) - the Mail bug appears back (that is, Mail is running in the background for 100% of the time, when plugged in/charging) - which is causing both 15 and 14 Pro to get really hot in the morning.

Simply because the titanium sides are getting warmer than other iPhone rails doesn't necessarily mean that the titanium itself is better at heat dissipation. Remember, they're using ALUMINUM as basically the main heat dissipator, and it is fused to the very thin layer of titanium. The titanium is actually doing almost NONE of the heat dissipation. And that's not even mentioning the fact that with all the overheating issues, you can't properly compare these side rails with previous iPhones, as the 15 PM may be getting even hotter internally, which will obviously lead to warmer side rails as well. That's just how heat works.

It means the side rails are better at heat dissipation. Because they are.

No, there are no unique overheating issues with the 15 Pro.

Except it literally doesn't. Again, if the entire device is producing more heat in general, then the sides heating up doesn't mean they're dissipating heat better.

And again, as I said, the heat dissipation would be from the aluminum, NOT the titanium

Not sure what you mean by this. If the aluminum is bonded to the side rails, then the dissipation has to be happening thru the aluminum AND titanium because the titanium is what's exposed to air. If you're referring to the aluminum back plate then sure, that's definitely accounting for most of the heat dissipation.

Except the device isn't producing more heat in general. Which you would know if you'd done any testing yourself or even bothered to stress test a 15 Pro and 14 Pro side by side.

It's almost impossible to get the stainless steel side rails to heat up, whereas the aluminium/titanium side rails heat up immediately. The difference is overwhelming and not something that could be caused by the difference in TDP between the A16 and A17 Pro.

And again, as I said, the heat dissipation would be from the aluminum, NOT the titanium

As I said, the side rails are able to dissipate far, far more heat with the 15 Pro compared to any of the stainless steel phones.

And you've got no evidence the 15 Pro has an "overheating" issue, because it doesn't.
 
It’s not the hardware, it’s the software and our lack of QC. We couldn’t be bothered to test our flagship product with some of the most common apps on the planet. That’s what our users are for.
It's not Apple's job to test their phones with Apps, it's the developers job to test their apps. It's what my team does, and out company buys the new phones to ensure they work.
 
13 Pro here, and after upgrading to ios17, I noticed my phone was running very hot, screen was dimming all the time, and battery life was suffering. It resolved itself a couple days ago. Sucks that we can't really get any visibility into what apps are causing the issues...can't exactly load a terminal and run top.

Kinda puts a wrench into Apple's whole "side loading apps would be a disaster!" thing...I mean even with the walled garden you have situations like this where they are approving apps for the App Store that have the potential to ruin the user experience with the device.

I believe this is a software issue though and not related at all to any specific chips or chip issues; at least it was for me.
They have no way of testing every app that's submitted to ensure it won't cause some end user problem on the myriad of iPhones and iPads that are out in the marketplace. It's the job of the app developer, same goes with computer software.

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.
If it was a hardware issue, pretty much every one would be experiencing it. Neither my wife or I have had any issues with our 15 Pros, nor have we've had issues with our 15 Pros in our development department.

No, the 14 Pro was machined from a block of stainless steel, with the components attached to the back. With the 15 Pro, Apple rearchitected the entire device to have an aluminum midframe fused to the titanium rail.
12 pro, 13 pro, 14 pro, all NOT solid stainless housings. The frames are stainless steel. The mid plates are aluminum. I tear these devices down regularly. 15 pro series has the same aluminum midframe. Only difference is the titanium outer frame. Which is much better for heat dissipation, hence why the frame of the phone is warmer this year when the phone does run at higher clock speeds.
 
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.
It is actually a titanium alloy. Grade 5 titanium is mixed. Titanium is far superior for heat dissipation as well, over stainless steel. Top of the line car exhausts are titanium. I think we will see better battery health stats this year being tue titanium is dissipating the heat better.

Wrong. What was said was:
"the titanium frame and aluminum substructure provide better heat dissipation than any previous-generation Pro models with stainless steel frames."

That statement is true. It is not about the thermal conductivity of the Titanium alloy, it is about the superior heat dissipation of the titanium frame and aluminum substructure.

All here babbling about simplistic conductivities of a single metal alloy are only babbling. Reread: iPhones are assemblies, with frame and aluminum substructure.
THANK YOU! This is why the heat can be felt more in the frame this year. Also explains people freaking out. They need to educate themselves.

While the titanium side frame part might be an alloy, it's bonded to the inner aluminum side frame.
