Apple Innovates Folding iPhone Thermal Management
Tap title to read story
Apple’s newest folding iPhone, the Duo, introduces a clever hinge‑based cooling system that keeps the device’s new A20 Pro chip running smoothly. Engineers routed a flexible graphite pipe through the hinge, allowing heat to transfer between the two halves and expanding the surface area for dissipation.
The A20 Pro, built on a two‑nanometer process, is Apple’s first iPhone chip of that scale, following the M6 chip’s debut in the Mac mini. The Duo also adds a second display engine to drive both screens simultaneously and places the FaceTime camera behind the inner display.
These innovations demonstrate Apple’s commitment to balancing performance with thermal safety in a foldable form factor. The Duo’s design showcases a new “metal over foam” material that bridges the chip and vapor chamber, providing a compliant, thermally efficient connection. This material, refined over months of development, meets strict mechanical
