Overview
The Apple iPhone Duo is Apple's first foldable iPhone, unveiled on September 9, 2026 and going on sale October 23 (pre-orders October 16). It opens like a book from a compact 5.4-inch outer Super Retina XDR OLED display into a 7.6-inch nano-texture inner panel with ProMotion up to 120Hz and 3,000 nits peak brightness, giving 50% more screen area than the iPhone 18 Pro Max. Beneath the Grade 5 titanium build with a precision 3D-printed hinge sits Apple's A20 Pro chip on a 2nm process with vapor-chamber cooling, a dual-battery system rated up to 44 hours of video playback, and an IP68 rating. It drops Face ID for Touch ID in the side button and pairs a 48MP Dual Fusion camera system (Main + Ultra Wide, no dedicated telephoto) with iOS 27's fold-specific features like Split View, Duo Preview, Smart Take and Duo FaceTime. The Duo is eSIM-only, uses Apple's C2 modem with Wi-Fi 7 and Bluetooth 6, and starts at $1,999 in Star White or Night Sky.
