Overview

• Multiple reports published on Aug. 27 say the iPhone 17 Pro and Pro Max are rumored to adopt a vapor chamber cooling system.
• The official event invite features a dynamic logo resembling an infrared heat map, which reporters interpret as a clue to upgraded thermal management.
• Outlets link the potential cooling change to the expected A19 Pro chip, suggesting longer sustained CPU and GPU performance with fewer throttling slowdowns.
• If accurate, the Pro models would be the first iPhones to use a vapor chamber, a design already present in some Android flagships such as Samsung's Galaxy S25 Ultra.
• Apple has not confirmed these details, with clarification anticipated at the Sept. 9 event that is also expected to spotlight other product updates.
