A Weibo tipster has revealed fresh details about Apple's rumored foldable smartphone, claiming the device will pack vapor chamber cooling for better thermal management. The leak suggests Apple achieved impressive vapor chamber performance despite design constraints.

Apple faces significant engineering challenges with the foldable's thin chassis, especially when unfolded. Integrating vapor chamber cooling into such a slim form factor shows the company is prioritizing sustained performance over basic functionality. This addresses a major pain point in current foldables that often throttle under load.

The same source indicates the iPhone Ultra will use a liquid metal hinge, potentially solving durability concerns that plague existing foldable devices. These materials choices suggest Apple is taking a premium approach rather than rushing to market.

Notably, vapor chamber cooling already debuted in the iPhone 17 Pro and 17 Pro Max lineup. If the foldable maintains the rumored September timeline, it would arrive alongside Apple's existing advanced cooling technology, giving the company more time to refine implementation.
