iPhone 17 Pro models may sport vapor chamber cooling system

All iPhone 17 models are expected include internal design enhancements for better heat management, with the iPhone 17 Pro models reportedly incorporating a new vapor chamber cooling system – a first for iPhones. The logo for Apple’s September 9th “Awe Dropping” event resembles an infrared heat map from a thermal camera, possibly hinting at these upgrades.

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.
Samsung’s Galaxy S25 Ultra and select other Android smartphones have a vapor chamber cooling system, but the iPhone has yet to offer such a feature.

MacDailyNews Take: Bring it on, our iPhone 16 Pro Max units can get quite toasty when under sustained load, especially when working outdoors on warm sunny days.
