iPhone 17 Pro's Alleged Vapor Chamber Cooling System Partly Revealed

[Andy_2341]

I have strong doubts about this.
Are you saying it doesn't even heat up duribg facetime video calls??

Yeah, it gets warm after a while, but I wouldn't call it overheating. I can still hold it and not think
"ouch, its burning me." Often though, I use it through continuity camera on my Mac mini connected to a wired charger for 2 or so hours at a time, case on. It wasn't any warmer than if I was to charge it on a MagSafe pad.

Edit:Grammar/spelling

13 Pro just overheated when mounted on my bike to ride for about half hour in temperate climate zone under heat wave (93 F, 34 C now) with the bike tracking app.
It is a more intensive and sustained task on me than the phone though. 🤣

Interesting to see the part but not sure whether the 17 Pro will have a vapor cooling system. If so, it will be good and hoping that the device does not get too hot in bright sunlight.

Apple has long tried to appear as an innovator, but there are many things in which it lags behind its competitors. Siri of course, but also those so-called "new" macOS/iOS features that have been present in Windows/Android for ages (by the way, you might have noticed that Apple recently stopped using its increasingly ironic "Mac does that" slogan).
Competitors from Samsung to Meta, from Huawei to Alphabet, have clearly become the lead innovators, and Apple indirectly aknowledges this when it says that its objective is not to be the first, but the best.

This has been rumored for every iPhone for the past like 5 years 😂

 

[Fandroid killer]

Apple's upcoming iPhone 17 Pro and iPhone 17 Pro Max models are rumored to be equipped with a vapor chamber cooling system, and a leaker known as Majin Bu today shared a photo of an alleged copper thermal plate for the system.

Many high-end Android smartphones like Samsung's Galaxy S25 Ultra are equipped with a vapor chamber cooling system, which can manage heat dissipation inside the devices more effectively than the graphite sheets used in iPhones. If this rumor is true, the iPhone 17 Pro models would be the first iPhone models to use a vapor chamber.

A vapor chamber would help to prevent the iPhone 17 Pro models from overheating during intensive, sustained tasks like gaming. It would consist of a thin, sealed metal chamber containing a small amount of liquid. When the iPhone heats up, the liquid would turn to vapor and dissipate across the chamber's surface area. Eventually, the vapor would cool down and condense, allowing for the process to repeat. This system would help to move heat away from the A19 Pro chip that is expected to power the iPhone 17 Pro models.

Majin Bu has a mixed track record with Apple rumors. Most recently, they accurately leaked that iPadOS 26 would add a Mac-like menu bar to the iPad, but they incorrectly claimed that iOS 26 would add Stage Manager to iPhone models with a USB-C port.

We cannot confirm if this component is actually related to the iPhone 17 Pro models, which are expected to be unveiled by Apple in September.

Ifans excited for features that have been out for decades😂

Better to charge overnight or with slower power bricks. Fast charging will be always hot. But you can use a lifehack to prevent extra heat: turn iPhone off and let it charge in this state, almost no heat generated

Another one that I've found was charge with low power mode on

 

[platinumaqua]

The best way to manage heat is to use silicon that consumes less power.

I feel like phone chips are so overpowered these days, they can limit the chip to 80% max power (pulling a random number here) full time and most people wouldn't be able to tell the performance difference.

 

[N0ughtsAndCr0sses]

So excited that this rumor is still around and seems to be legit. It’s probably the single feature that will make me upgrade from my 15 Pro Max. Fingers crossed for much less display dimming and overheating!

Same device


Still in two minds, mate
Most likely I’ll give into the stupid temptation especially with the recycle ♻️ value.

Tut


Only human 😆

 

[dannyyankou]

Can we please start with iPhones not immediately overheating when used outside and keeping the display readable and not turning down to 0% when exposed to a bit of sun light?

Unfortunately, as long as the iPhone is made of glass and metal, it’s always going to get hot in direct sunlight. Car makers have been dealing with the same problem forever.

Apple's operation system feature reveals happen in two main stages. First at WWDC and then in September when new hardware is announced that often get new exclusive features in that year's OS release.

An iPhone that can be plugged into a display, keyboard and mouse and then operated like a desktop with Stage Manager sounds very much like a feature that can be sold as an exclusive to that year's pro hardware. I'd wait until September before dismissing the claim.

 

[emrelee]

That's basically how fridges works since 1834, but it’s always exciting when Apple explains how they’re the first to come up with an "old" new idea at their events.

 

[Zerlina]

idk but if this leak ends up becoming true then this will be my only reason of upgrading

Lordy lordy yes please. My stupidity for putting the iOS26 dev beta on my main driver and I guess it's playing a part. But don't be out in the heat and directly under the sun with an iPhone unless you want a hot had and screen that gets less readable than a Gameboy color screen in the sun. Ridiculous.

iPhone could be perfect but Apple loved dragging their feet with quality of life updates. While at it came we please get a universal solution for clearing red badge notifications? Tired of broken app showing notifications, I clear them all, and I still see at least 1 red badge over an app.

 

[LavaShark]

What are y’all doing with your iPhones to make them get hot so easily? My SE3 overheated 1 time after . My 15 Pro has never overheated and I take advantage of full brightness in direct sunlight often as well as game at max settings connected to an external 4k monitor.

Of course, I’m still excited for the vapor chamber.

Gotta go to my work. Summers where I am are hot and we're a high humidity environment and there's a heatwave right now. My 15 Pro Max hasn't really had many over hearing issues on it's own but in this crazy summer heat it sure will have an effect of these titanium and glass rectangles 😢

 

[LavaShark]

Heh, surprised it is not just my 78% iPhone 11 Pro doing this stuff😃

I am trying not to use it in hot areas, it overheats to infinity.


They are holding it for iOS 27😁

How? Like can you do this and not have the phone fully turned on? My phone always turns on when I charge it while off. Or is that the point? Are you just saying that it's better to charge from a powered off state?

 

[segfaultdotorg]

If Apple were truly committed to innovation, we’d get a proper cooling fan instead of this vaporware.

No problem with this if true, however as soon as you put the phone in any sort of case made of plastic the it will insulate the phone and prevent it radiating the heat away. The case would need to be conductive where the heat reaches the metal case.

Good point, Pedro. He said all iPhone models with a USB-C port, though.

 

[zenmacx]

If true this is a step in the right direction, as the current iPhone 16 Pro Max I'm using warms up all too easily as did its predecessor's.

Also this presents a golden opportunity to skip iPhone 17 and give them time to work out the issues that are sure to arise in its first year of use by consumers.

Perhaps by iPhone 18 or whatever they name it, the cooling system will be effective and reliable.

Can we please start with iPhones not immediately overheating when used outside and keeping the display readable and not turning down to 0% when exposed to a bit of sun light?

My 16 pro works well in the heat and sun. I'm often using it outside on 100F+ days with no real problems with heat or display brightness.

 

[cbdilger]

Liquid cooling? Oh no, not again...

 

[Andy_2341]

Liquid cooling? Oh no, not again...

Mmm, it’s a bit different set up though.

Hear. Hear.

Why would you do that???
