Apple reveals A20 Pro chip details for iPhone Duo foldable

Apple has revealed details about the A20 Pro chip in its first foldable phone, the iPhone Duo, highlighting unique features tailored to its design. The chip includes a second display engine and a new "metal on foam" material for thermal management. The second display engine allows simultaneous operation of the internal and external screens, ensuring a smooth user experience. The "metal on foam" material connects the chip to the vapor chamber, dissipating heat effectively while meeting mechanical requirements. A flexible graphite tube inside the hinge transfers heat between the device's two halves, enduring repeated open-and-close cycles. This addresses the thermal challenge of the phone's doubled volume when folded.
