Overview
- Apple disclosed a foldable-specific thermal system that uses a flexible graphite heat pipe through the hinge to move heat between the two halves and increase dissipation surface area.
- The company described four heat‑management pillars — direct silicon access, a metal‑over‑foam thermal bridge, a vapor chamber with roughly three times the surface area and a nanotube copper display plate — to spread and move heat away from the A20 Pro.
- The Duo runs a 2 nm A20 Pro variant packaged as a wafer‑level multichip module that places DRAM beside the processor, and Apple added a second display engine plus under‑display FaceTime camera support to drive both screens.
- U.S. preorders begin Friday, October 16, with first deliveries on October 23 and U.S. pricing starting at $1,999; the phone is eSIM‑only, uses Touch ID in the side button, and lacks Face ID and a dedicated telephoto lens.
- Analysts and supply‑chain reports say early production yields were low, Apple positions the Duo as a low‑volume premium product, and strong demand has drawn reseller interest and warnings about pre‑order bots and scams.
