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.

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?

They say they have improved the cooling with every generation since the iPhone 13, but it’s still the same problem because the performance gains of the chip offset the improvements in cooling.
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!

Ha exactly. It doesn’t even take that much sun. I’d say the sun issue and the fact that the phones get pretty darn hot with fast charging are big annoyances. Maybe this will help with the charging issue?
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.
Biggest design overhaul since iOS 7 with Liquid Glass, plus new Apple Intelligence features and improvements to Messages, Phone, Safari, Shortcuts, and more. Developer beta available now ahead of public beta in July.
