Apple’s upcoming iPhone 17 Pro might be getting a much-needed upgrade in the cooling department. According to recent leaks, Apple is planning to add a vapor chamber cooling system — a thermal solution all Android flagships and even most mid-range phones have been using for years — to help handle the growing demands of gaming, AI, and similar resource-intensive tasks.
This type of thermal solution uses fluid evaporation and condensation to quickly move heat away from key components to the chassis. It’s significantly more efficient than the copper heat spreaders and graphite sheets of the current iPhones.
This change could make a big difference. The iPhone 16 Pro, for instance, reportedly suffered up to a 40% GPU performance drop during sustained workloads. With the iPhone 17 Pro expected to house the new A19 Pro chip, a better cooling system isn’t just welcome, it’s reportedly essential.

The vapor chamber is also said to extend to the memory, modem, and even the rear camera module. That could help reduce heat-related issues during long 4K/8K video recordings or on-device AI-based tasks. With iOS 19 likely to lean heavily into on-device AI features, especially around Siri, keeping the chip cool will be key to maintaining smooth and consistent performance. Unfortunately, the non-Pro iPhone 17 models will continue to rely on the copper heat spreaders and graphite sheets.
If these leaks hold true, the iPhone 17 Pro might finally offer the much-needed thermal headroom Android devices have had for years. We’ll know more when Apple unveils the device, expected around September 2025.
