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

[Allen_Wentz]

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.

Titanium Vs Stainless Steel: Which Metal is Right for Your Project?

Titanium may be the right choice for your project if you’re looking for a lightweight yet strong material with superior corrosion resistance.

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.

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.

I’m sure the next lawsuit is already knocking on their door.

Anyway it’s so funny to see people defending Apple in all kind of ways like… Apple has eaten my child, nooo your child ran into Apples mouth, it’s your child fault.

Glad they’re jumping on this. Did no one test these apps before release?

Apparently the app-specific issues only happen on the iPhone 15 (Pro), which the app developers may not have available to test on, after they successfully tested their release on the iOS 17 betas/RC.

Not sure if Apple is doing much testing of third-party apps on new hardware. They’re certainly less concerned about backwards compatibility then say Microsoft for Windows, and usually let the app developers sort things out.

Remember antennagate and bendgate? Apple will 100% mislead if it avoids a hardware recall.

I wonder if any of these bugs being fixed will further improve battery life overall on the 15 Pro.

 

[Allen_Wentz]

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.

Of course the lighter/stronger Titanium alloy used means that yes, they changed the thermal design. And it is better.

Apple is taking a page from the fanboys and is blaming the apps. I guess the Apple phone app should be added to the list since multiple people report being on a phone call generates a high heat condition.

 

[SebCohen]

Not just 15s….my iPad Pro 12.9 M1 gets insanely hot during normal use, ie Safari’ing. Yes, it normally gets hotter after an update, but this ramps up almost instantly from sleep. And it starts stuttering during normal use as well. But besides that, it’s a good update.

 

[Waragainstsleep]

So if these apps affect the A17 Pro and the Pro iPhones have better heat dissipation than the regular ones, why aren't the regular iPhone 15s also overheating?

 

[ifxf]

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.

If it is the apps why doesn’t Apple have a report for high battery draws like they do on the mac?

 

[spiderman0616]

But rando's on the interwebs with no technical metalworking knowledge and no development experience with the 15Pro's said its the titanium. 🥲

"Who are you going to believe, me or your lying eyes?" 😎

It’s amazing isn’t it? I never knew we had such a brain trust of metallurgists, industrial designers, and software developers in our midst. It’s a wonder Apple hasn’t sucked these people right up and given them a 401k!

For those of you that have this heating issue, do you notice the battery getting drained faster when it occurs?

 

[jarman92]

Remember antennagate and bendgate? Apple will 100% mislead if it avoids a hardware recall.

There's an enormous difference between downplaying an issue and deliberately making false statements. Here, Apple has said they will not reduce performance; that's a pretty definitive statement that, if false, can easily be disproven. There's absolutely no way Apple would make such a statement if it weren't true.

And there is precisely zero chance of a hardware recall here, whether Apple fixes the bug(s) or not.

 

[jarman92]

So if these apps affect the A17 Pro and the Pro iPhones have better heat dissipation than the regular ones, why aren't the regular iPhone 15s also overheating?

Probably because the non-Pro 15s have an A16, not an A17 Pro.

 

[jarman92]

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.

They very obviously changed the thermal design. You should read stories before commenting on them.

 

[Dirty Mac]

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!

Sonama has been wonderful for me so far... now lets talk about my last remaining windows 11 desktop running the insider canary builds if one wants omg this is getting worse.

 

[Mr. Dee]

Ming Cho and his educated guesses failed again. Mark Zuckerbergs time wasting apps isn't surprising for causing this. They have been notorious battery killers for a good while now.

 

[t0rqx]

Wow. The news must have made a big negative impact for Apple stepping out and addressing this issue. Good if it is true that 3rd party apps are the culprit.

 

[hans1972]

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.

Apple said it was recent changes to those apps.

 

[dantay]

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.

Trillion dollar company makes fundamental mistake……..highly unlikely.

 

[hans1972]

Titanium has poor heat conductivity I believe, so did Apple used their $$$$ to create a new kind of Titanium alloy that is not like this?

I believe if Apple made the iPhone 15 Pro Max out of Aluminium, the phones would be less likely to overheat.

Yes, but the iPhone 14 had stainless steel which is what you need to compare it to.

 

[bradl]

Sad to see. This would have never got past Steve. Apple has been going downhill for a few years now

Yet Antennagate and the iPhone 4 did.

Absolute fallacy, this statement is.

BL.

 

[hans1972]

Classic Apple defending themselves again of course it’s a hardware issue and titanium is that issue

Much more likely to be software.

You only need one programmer to take down an entire data center. They would have no problems causing performance issue on a mere phone.
