Apple iPhone 17 Pro: Leak reveals enhanced cooling system for A19 Pro and cameras

Whilst the Apple iPhone 16 Pro already boasts a more effective cooling system than the iPhone 15 Pro, our testing showed that its GPU performance can still drop by around 40% under sustained load, significantly affecting gaming performance. Leaker Majin Bu Official recently obtained new insights into how Apple plans to address this issue. 

The iPhone 17 Pro and iPhone 17 Pro Max will reportedly come with a completely overhauled cooling system incorporating a vapour chamber – an element that has essentially been a standard feature for years in high-end Android smartphones. As shown in the photo below, Apple appears to use a relatively large copper base, potentially enabling the vapour chamber to cover not just the processor but also components like the memory and modem.

Vapour chambers contain a working fluid that evaporates when heated at one end and condenses at the other. This mechanism allows them to dissipate heat more efficiently than conventional copper heat sinks. Prolonged processor-intensive applications, such as gaming, AI workflows and video exports, stand to benefit especially from this enhanced cooling system. According to the leaker, this is a very crucial upgrade since the Apple A19 Pro is said to produce even more heat than the A18 Pro. The vapour chamber is also set to cover the camera module, presumably to keep the sensors cool during extended video recording, thus reducing image noise and preventing potential overheating.
