Apple's iPhone Ultra Hinge Acts as a Heatsink with Liquidmetal Build
Rumors claim the iPhone Ultra foldable will use a vacuum/ vapor chamber cooling system and a heat‑transfer hinge that doubles as a heatsink, with the hinge made from Liquidmetal for added strength. Apple allegedly designs a dedicated heat path to compensate Liquidmetal’s relatively poor thermal conductivity, though the device's IP68 status remains unconfirmed.
