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

Lotta nonsensical words. Not "iPhones clearly have a design flaw." There is a software issue (apparently identified) that causes some 15s to overheat. iOS and apps will quickly evolve to fix it.
The software fix will throttle the processor because the software has no other ways to control the heat (unlike DIY PCs, the phone does not have the fans that software could speed up). The processor will be throttled well below it's unsafe temperature threshold and it's a design flaw. One can always throttle the processor to death thus avoiding any heat related issues. But that's a very flawed design.
 
That is simply untrue. A facade simply means the outer portion. I’ve made no statements, one way or the other, whether this makes the frame stronger/weaker, better/worse, etc. That the majority of the frame is aluminum is demonstrably true, as shown in the video I posted, in which someone cut and measured the cross-section of the frame. You can rage reply, argue, and make personal attacks all your want, but it doesn’t change that it is factually true that the frame is primarily aluminum with a 1-mm Grade 5 titanium facade. You may not like it, but that is what Apple has chosen to do.
Firstly, I've not personally attacked you. I’ve called your argument boorish. I say that because you continue the fallacy you have created. I believe you have chosen to deliberately ignore what the actual word, facade means. Stick with that word if you want, even though you’re using it incorrectly.

It is more than just a finish. It’s like calling an exoskeleton of an arthropod 'just for looks'. Is a grasshoppers looks a facade?

So what that it’s a millimetre thick. So I’m not sure that you could say without any qualification that it has more aluminium in the structure. Zacks video, btw shows there is also about 1mm of aluminium.

Aluminium has about 1/7th the strength of stainless steel and titanium. So how do you think the iPhone 15 pro gets its strength?

Why do you think they put Titanium on the outside? Is it just about the look? No. It also is much less corrosive than aluminium across water, air, oil, acid, and alkalis. Aluminium isn’t. It is also 1/16th the heat conductivity of Aluminium.

It is hardly a facade, it provides, strength, lightness, thermal barrier, less corrosiveness and it can have embedded colour throughout. It is much more than a facade.
 
Nope, you’re making bad faith assumptions because you’re looking for a reason to rage reply. From the Cambridge dictionary, a facade is the, “the front of a building” and “A person’s façade is the image that person presents to others.” Facade is a perfectly accurate word to refer to the 1-mm of titanium, which is the front of a majority aluminum frame and is what is presented to others. Just because you don’t like that Apple chose to use a majority aluminum frame with a 1-mm Grade 5 titanium facade doesn’t change the fact that it is intentionally misleading to claim the entire frame is titanium.
Why do you keep saying it’s a majority of aluminium? Where is this shown? Zack shows it is about the same. And where does anyone say that the entire frame is titanium? Every thing specifically says it’s titanium bonded with aluminium. Plus who even suggests, other than you, that the structure is primarily from the aluminium?

You’re wrong, and there is no little point in continuing a discussion with someone so closed minded.

You can continue to make personal attacks but it doesn’t change the factually accurate description of 1 mm of titanium over a majority aluminum frame as a facade. It is the outer portion that everyone sees, the very definition of a facade. Contrary to what you falsely claim in your bad faith rage replies, a facade can provide structure, can provide protection, etc. In fact, in some cases, like marble facades of medieval and renaissance churches, the facade is stronger than the underlying structure and provides superior protection than the underlying materials (e.g., more porous stone and wood). However, because the material is more costly, the material is only used as the facade. Just because you don’t like something Apple has chosen to do doesn’t change what Apple does.

That’s not remotely what he showed. In the cross section, the majority of the frame was aluminum, with a 1-mm Grade 5 titanium facade. In fact, in the video I shared, JRE says, “It’s definitely not a full titanium frame of course, more of a titanium adornment.”

You are wrong and there is little point in continuing a discussion with someone who makes bad faith rage replies and refuses to accept the objective truth when presented to them.

Sigh… And it’s Zack btw. He hates anyone calling him JerryRig. Bit of respect for the man please, even if you can't respect others opinions. If you were in anyway familiar with his sense of humour, you would know exactly what he is talking about. He lives on sarcasm. If it were just an adornment, it would be a facade, like the argument you seem to be sticking with.

I’ve not once personally attacked you (please show me where), and I’ve not once raged, with or without bold text. When you’re going to provide objective truth, I’ll answer accordingly, but your claims are opinion based on a subjective perception. I have actually listened to your bold claims. And they just don’t stack up.

I notice you ignored any comments by myself or others on external structures.

Nonsense. Ti conducts heat worse off than aluminium. It Ti were so good, why wasn’t it used in cookware?
Doesn’t seem like, it. I can’t claim for the accuracy, but I found this anyway. Can you provide a source that shows that thermal conductivity of aluminium is better?​

Aluminum Vs Titanium #7: Heat-conducting Property​

The thermal conductivity of aluminum is about 237 W/(m·K), while the thermal conductivity of titanium is about 15.24 W/(m·K). This means that aluminum conducts heat almost 16 times better than titanium. The higher the value, the better the thermal conductivity.​

Sigh… You are making absolutely no sense. I posted the video, which shows the objective truth that the majority of the frame is aluminum, with a 1-mm facade of Grade 5 titanium. Because all you want to do is make personal attacks and rage reply, you’re now denying what Zach actually said in the video. It wasn’t sarcastic - he was using an actual tool to make measurements. Bit of respect, please, even if you can’t respect objective truth over your subjective statements.

I see you continue to ignore what I say and what the video and objective measurements show. Your claims are based on willful refusal to accept objective truth. I also noticed you ignored that I said, multiple times, I’m making no claims about this making the frame poorer in strength, quality, thermal conductivity, etc.

Majority? Wow.

The processor will be throttled well below it's unsafe temperature threshold and it's a design flaw. One can always throttle the processor to death thus avoiding any heat related issues. But that's a very flawed design.

They don't need to throttle anything if they simply fix the bug that causes the CPU utilization to spike when it shouldn't. There is zero evidence that they need to throttle anything to fix the problem.

Doesn't sound like you have a background in software engineering, but there are plenty of ways that bugs can make it into software that cause performance issues and the fix is not "throttling" the CPU - it's fixing the bugs.

Notice how these problems mostly happen with the would-be-pro devices...

I used to get my iPhones at launch, but I'm happier and happier to wait, nowadays.

Provided I'll be able to afford it, I'm planning to get the 15pro around february.
 
I suspect apple didn't really source genuine "AEROSPACE-grade" titanium went with the lesser-cost toilet-grade Ti

The majority of the frame is aluminum, which dissipates heat better than titanium. More likely it is either software entirely or software and some hardware defects.
 
Perhaps it was subsequent app updates post iOS 17 "going gold" that caused the issue?



I guess it is a matter of semantics. The A17 Pro (hardware) is generating the heat, but it is generating the heat because some applications (software) are triggering the A17 Pro cores to run longer and harder than they should.
The only thing I’m not buying about this is that my 15 Pro Max seems to get hot when 1) using the stock camera app, and 2) using driving with CarPlay.
 
Exactly.
Titanium layer is quite small (~1mm). But their fusing result is quite masterpiece of engineering.

At 9:00 Zack (not Jerry ;D ) cuts down a frame of iPhone 15Pro
Apple should have used a solid titanium for the whole frame of the phone, not just effectively a cap over the frame. Technically its a titanium plating so the term “titanium” should be used sparingly - just like gold plated is not solid gold.

Can I ask why they “should” have done that? Is there a particular benefit you had in mind that offsets any weight, mass manufacturing, or performance compromises that might have to be made to do that?
 
That's just BS. All processors are designed to monitor their temperature and throttle when the temperature rises too high. iPhones clearly have a design flaw.

There is so much baseless simplistic low info reasoning in your post I almost don't know when to begin. If there is a design flaw with the 15 Pro, why does the 15 Pro not run meaningfully hotter than a 12/13/14 Pro? Out of the 4 or 5 people making this claim, will you be the very first not to duck this question?

The processor also should not get so hot as to make the phone itself uncomfortable to touch. Depending on the design of the phone cooling system, one or another threshold could be lower. In this case, despite of what Apple is saying, it looks like phone coling system is poor.

What evidence do you have that the cooling system is poor? The phone doesn't get hotter to the touch than the 12/13/14 Pro in any meaningful way, so again, what evidence do you have to keep making this claim?

The processor gets hot (but not too hot as to fail) and it heats the case too much.

According to what?

Apple saying that non-optimized apps cause the overheating is pure BS too. Apps have no control over the device temperature and they are not supposed to monitor it. It's the processor and the whole device (OS, sensors etc.) that should monitor the temps and throttle the apps as necessary. The app will always try to get as much resources as it needs. What Apple is implying is that if you only run the simple apps which do not require much in terms of processing power (aka "optimized apps") the phone will never overheat. The assumption is that their users are stupid and won't bblame them for design flaws.

This shows a complete misunderstanding of how any of that works. Firstly, the iPhones are not "overheating", they are just being run under full or close to full load and heating up. Again, not overheating, just running as if under full load. Anyone who knows anything about this will understand that a rogue app or bug can cause a device to run under full load inappropriately.

What I don't understand is, given you appear to have 0 understanding of how any of this works, and a complete ignorance of the facts, why are you compelled to write this post?
