Vapor Chamber Tech Keeps iPhone 17 Pro Cool

https://spectrum.ieee.org/iphone-17-pro-vapor-chamber
25•rbanffy•3h ago

Comments

leakycap•2h ago
I'm interested to see how many/few complaints we see about the iPhone Air overheating, since it has almost the exact same chip as the 17 Pro but a simpler cooling system

"My phone is really hot, is this normal or is it broken?!" is something I started getting asked by random iPhone-using friends over the last few years as they upgraded to a new model and then felt it sizzling.

thewebguyd•1h ago
Got my air yesterday and it definitely gets hot. Will see how it does after a few days as I expected the heat due to the initial sync and transfer, and iOS indexes everything for a day or two.

But even then it was no hotter than my 16 Pro

reaperducer•1h ago
Got my air yesterday and it definitely gets hot. Will see how it does after a few days as I expected the heat due to the initial sync and transfer, and iOS indexes everything for a day or two.

I have one, too, and you're right that the heating is just what happens while it restores its data and settings and whatnot.

I believe it also re-scans your entire photo library to re-identify dogs, cars, people, etc. with whatever improved algorithm comes with the new chip/OS.

This happens every time you get a new iPhone. Depending on how much it has to sort through, it can take a couple of hours to a week.

I always leave the case off for the first few days.

jtokoph•1h ago
I figure it will just be clocked down to maintain thermals
Wistar•1h ago
Last night I encountered a 3 min+ ad on YT about the construction of the iPhone 17 Pro. A few seconds were devoted to the cooling system. I watched the whole thing. It was better than the video it interrupted.

https://youtu.be/_-AS5DtDeqs?si=rTfubRDArVupqREt

VertanaNinjai•41m ago
This might be the first time I’ve seen someone happy about an advertisement in the wild. It is a cool video though!
supriyo-biswas•33m ago
The ads for ReMarkable 2 and Apple’s Don’t Blink are quite captivating and entertaining in a way that I can’t claim about typical advertising.
cj•39m ago
Watching that video, the first thought I have is "So much engineering and I still need to buy a phone case with my new phone?"

I'm guessing phone cases are still pretty much required if you drop your phone once or twice a month onto cement/asphalt/marble/etc from pocket height.

I would be really curious to hear the internal debate at Apple wrt design tradeoffs + durability. E.g. how much of the iPhone design is only possible because Apple is assuming the average person will have a case on their phone.

I wouldn't be surprised if the typical consumer would be more impressed by "No Case Required iPhone" compared to "Skinniest and lightest iPhone yet!".

JumpCrisscross•37m ago
> I still need to buy a phone case with my new phone?

…you don’t. I don’t. My phone is scratched here and there, but not in a way that I notice. I used to defend this with my purchasing of insurance, but frankly, I crack the screen now maybe once every 2+ years.

> Apple is assuming the average person will have a case on their phone

I think it is fair to assume that irrespective of the design, most people will case their phones. Leaning into that is fine as long as the phone is still functional without a case. (Which, again, every iPhone in the last decade has been.)

cj•27m ago
> functional without a case. (Which, again, every iPhone in the last decade has been.

Agreed they're functional without a case.

Whether it's functional after dropping it face down on the glass onto cement/marble is another question!

I'm not too concerned with cosmetic scratches. The main issue is the screen shattering. And the back of the phone shattering in older models where the back was glass.

ziml77•29m ago
How do you propose making a device that people wouldn't feel the need to put a case on? You could make the whole thing out of rubber but that's still going to take cosmetic damage that people want to protect the device from. You could make it easy to replace that rubber... but at what point is that not just functionally the same as a case?
cj•17m ago
> How do you propose making a device that people wouldn't feel the need to put a case on?

If the screen were reasonably scratch + shatter proof, I think most people wouldn't feel the need to wear a case.

cassianoleal•6m ago
I don't use a case or screen protectors. My 15 Pro frequently falls on the floor. The back shattered on multiple occasions, but even then never became a cut hazard. The screen remains pristine.
deadbabe•1h ago
I have an iPhone Air now and have no complaints about the heating. The thinness is worth the occasional heat and throttle down. Every time I pick up this phone, it just feels fantastic!
TheCraiggers•57m ago
Serious question: how is the thinness providing value? Is it simply the feel?
lysace•47m ago
Back when I had the iPhone 5S (7.6 mm vs the 5.6 mm of the iPhone 17 Air): It provided value in terms of feel. It felt like a piece of art meeting cutting edge technology. It wasn't about showing off.
reaperducer•40m ago
Nothing feels better than the original iPhone.

Solid, tactile, and just the right size. Mine finally got stuck in a boot loop earlier this year, but I keep it in my desk drawer, and pick it up occasionally. The mute switch (an actual switch, not a button) is still the best.

reaperducer•42m ago
Every time I pick up this phone, it just feels fantastic!

I find that I treat it very gingerly. Something in my mind expects it to be fragile; presumably because it's thin and looks like glass.

kasperset•1h ago
Phone usage is getting more intense as we move from mere passive consumption to having them as creative (compute) device. "Heat" is sort of reflection of that.

I want to see more optimization to reduce the heat from both hardware as in this case and in software side as well. I guess it is easier to show enhancements about hardware made to address something such as heat or processing but comparatively difficult or abstract to show software optimizations?

leakyfilter•55m ago
From a keynote perspective, I guess showing software optimizations is less cinematic and not everyone can appreciate them as opposed to new or beautiful looking hardware.

Why the emphasis on Apple when Samsung was there first?

It looks like the competition is making them sweat (pun intended).

jjice•1h ago
But the sweat is evaporating now, at least.

But seriously though, I think it's just due to larger market share (at least in the US), so more people are seeing it and commenting on it.

TheCraiggers•1h ago
You should know how this goes by now. It's not like this is the first time Apple introduced an old technology but marketed it like they invented sliced bread. I give their marketing team credit.
bapak•56m ago
Samsung is not Apple. Relatively no one cares about Samsung outside Korea.
orev•39m ago
Literally in the subheading:

> Apple joins Samsung and Google in managing heat

nicce•33m ago
Usually it is sign for stability and usefulness if Apple adapts it. They rarely add something very new for mass production.
GrabbinD33ze69•32m ago
Because average people "care" about Apple far more than their peers.
numpad0•24m ago
Samsung is definitely NOT the first.

Can this tech be used for EV batteries?
TheCraiggers•59m ago
I guess? But vapor chambers are mostly good where space is a premium and where passive (non-powered) cooling is enough.

I'm guessing for EV batteries, better options exist since you obviously have power. Although sometimes vapor chambers are used in conjunction with active cooling.

lazide•46m ago
Heat pumps are way better if you have to manage a lot of heat anyway.
Tagbert•13m ago
EV batteries have active cooling systems that force cool air through the packs.
lysace•1h ago
Not exactly brand new tech, but now on a mobile device without the long-term security baggage that often comes from using Android.
bigyabai•49m ago
I think NSO Group has pretty thoroughly demonstrated that iOS users aren't exonerated from security concerns.
lysace•45m ago
Yes, state actors will be able to breach into your iOS device if you're deemed important enough.

Edit: Meanwhile your average Android device has multiple publicly known remote execution issues.

bigyabai•44m ago
Yup. Pretty similar to the modern threat profile of Android, all things considered.

> your average Android device has multiple publicly known remote execution issues.

Help me distinguish between "publicly known" RCE vulns and private ones. Do the privately owned exploits like FORCEDENTRY count as "publicly known", or only the Greykey/Cellebrite exploits used by governments?

JumpCrisscross•34m ago
> Pretty similar to the modern threat profile of Android, all things considered

I don’t think this is accurate. Not even every nation-state would be expected to have access to iPhone zero days, particularly with the new memory protection rolling out.

bigyabai•26m ago
I don't think that's accurate, either. NSO Group sold their exploits to several other nation-states, seemingly without much (any...?) vetting concerning the ethics of their government.
lysace•31m ago
Apple’s primary motivation is to sell hardware. Their brand is hurt if their direct customers suffer damages through malware.

Google’s primary motivation is to sell ads. Their brand is not hurt if phone brand FlirpleFoo ships millions of Android devices and then hurts those customers by not keeping those devices secure.

Aerbil313•34m ago
With iPhone 17 line the security situation has improved dramatically. I'm not a cybersecurity researcher, but Apple says even nation-state actors will struggle to breach a single device with the newly introduced Memory Integrity Enforcement mechanism. Their research appears legit:

Oh, I remember when they said this about Blastdoor too!

This is a heat pipe. A technology from the 60s. Your laptop almost certainly has heat pipes in it. They usually use alcohol rather than water as the phase change material though. The (relatively) novel thing is that it's packaged small enough to be in a phone. I suspect the only reason it hasn't been used in handhelds more is because the TDP of mobile processors wasn't high enough to warrant it.
Onavo•50m ago
It's a little bit older than just the 60s..
JoBrad•47m ago
As I understand it, it’s more than that: there are small “inverted pyramids” that cause the water to condense more rapidly, to extract even more heat from the system.

https://youtu.be/qAZ-q3KmDHM?si=pb08RMHEAA4o94xF

esperent•40m ago
Heat pipes are one dimensional (a pipe), vapor chambers are two dimensional (a square chamber). Most vapor chambers I've seen on GPUs have the chamber attached to lots of small heat pipes on the side though (they even note this in article, in case you feel like reading it).

That said, I assume the main technical breakthrough here is in manufacturing, producing tiny chambers consistently in enough volume for iphones.

0_____0•8m ago
Any passive phase change thermal solution is doing the same thing - take thermal energy from one place, and distribute it for dissipation. My point is that the geometric configuration isn't that important, it's doing the same work the same way. Not really worth arguing about, I just suspect that the branding people love that they had a new buzzword in "vapor chamber" to bandy about.

I liked this article from 10 years ago that actually goes into detail about how Fujitsu actually constructed a super-thin heat pipe (really just a very long vapor chamber) https://spectrum.ieee.org/superslim-liquid-loop-will-keep-fu...

numpad0•39m ago
Also on some Android gaming phones since 2018. Regular heat pipes on phones dates back to at least 2013.
jml7c5•41m ago
Oppo uses these in some of their phones. They gave a factory tour to the "Know Art" Youtube channel, which made a good video on it: https://youtu.be/qAZ-q3KmDHM
orev•35m ago
Which most people are going to immediately cover with an insulating layer of plastic or silicone.

At least the heat will be spread out from one spot (and into the battery?). All phone makers are doing what they can within the design constraints.

jrowen•29m ago
Why have none of the major players tried integrating a case? Making a ruggedized version? They could probably do a lot better and find ways to innovate with something integrated.

Why do they ignore the fact that so many people use cases (and the market opportunity)? It's almost a defect at this point. Some people like the personalization but I think a lot of people just want something that won't break when you drop it...

vlovich123•2m ago
Lots of reasons. The most obvious ones that come to mind:

1. People like a variety of custom cases that themselves have features (eg wallet cases random designs etc). If it’s built into the phone that customization capability is worse because you now have two layers of protection making for a very thick and heat-insulating design.

2. It’s valuable to have partners that make accessories for your device. If you kill that line of business for them, other things may go away and those partners will want to work with you less.

3. An integrated case will still suffer cosmetic damage. But now without the option to replace, you’re stuck with that damage.
