Apple’s upcoming iPhone 17 Pro may receive a much-needed cooling upgrade. To meet the increasing demands of gaming, artificial intelligence, and other resource-intensive tasks, Apple is reportedly planning to install a vapour chamber cooling system, a thermal solution that has been used for years by all Android flagships and even the majority of mid-range phones.
This thermal solution rapidly transfers heat from important parts to the chassis through fluid evaporation and condensation. It is noticeably more efficient than the graphite sheets and copper heat spreaders found in the current iPhones.
This modification might have a significant impact. For example, it was reported that the iPhone 16 Pro experienced a 40% decrease in GPU performance when subjected to prolonged workloads. Better cooling is welcome and supposedly necessary since the iPhone 17 Pro is anticipated to house the new A19 Pro chip.
It is also claimed that the modem, memory, and even the rear camera module are all included in the vapour chamber. That might lessen heat-related problems during lengthy 4K or 8K video recordings or AI-based tasks performed on the device. Since iOS 19 will probably rely a lot on on-device AI capabilities, particularly regarding Siri, keeping the chip cool will be essential to ensuring steady and fluid performance. Regretfully, graphite sheets and copper heat spreaders will still be used in the non-Pro iPhone 17 models.
