Overview
- Apple confirmed preorders for the iPhone Duo will begin on October 16 with shipments starting October 23 and a U.S. starting price of $1,999.
- Design leaders say the Duo borrows proportions from notebooks and the international A-series paper system so the device stays pocketable when closed and retains the same aspect ratio when opened.
- Hardware engineers describe a custom variable-torque hinge tuned to feel solid, hold partial angles and resist becoming floppy over time.
- Apple built a layered ultra-thin glass inner panel with a matte nano-texture coating that it says cuts glare and makes the fold visually and tactilely less noticeable, and an early hands-on reviewer reported not feeling a crease.
- The Duo runs Apple’s A20 Pro 2nm chip, uses fold-aware software that keeps controls familiar when you open it, and is likely to remain a premium, limited-volume product because of complex parts and hinge production constraints.
