iPhone 17 Pro tipped to feature advanced vapour chamber cooling system: Here’s what it means

It appears that Apple may finally be integrating a vapour chamber in upcoming

iPhone 17 Pro

and iPhone 17 Pro Max. According to a new leak by MajinBu, the two Pro models of the upcoming

iPhone 17 series

is said to come with vapor chamber cooling system, a technology already common in high-end Android devices like the Galaxy S25 Ultra. The popular tipster shared an image of a copper thermal plate which is said to be a part Apple’s new cooling system. The component talked about in the leak is expected to be central part of the vapour chamber. Unlike the graphite sheets traditionally used in iPhones for heat dissipation, a vapour chamber employs a thin, sealed metal chamber containing a small amount of liquid. When the device's processor (expected to be the new

A19 Pro chip

, rumoured to generate substantial heat) warms up, the liquid evaporates, turning into vapour. This vapour then spreads across the chamber, carrying heat away from the hot spots. As it reaches cooler areas, it condenses back into liquid, and the process repeats, continuously moving heat away from critical components.This technology is said to be important for preventing

thermal throttling

, a common issue where devices reduce performance to avoid overheating during intensive tasks like extended gaming sessions, 4K or 8K video recording, or demanding AI computations.The decision to integrate vapor chamber cooling into the iPhone 17 Pro models is seen as a direct response to the escalating power requirements of Apple's latest chipsets and the increasing demand for on-device AI processing capabilities expected with iOS 26.
