Overview
- Apple introduced the iPhone Duo as its first book‑style foldable with a premium price around $1,999 and the device is being offered with preorders and an October shipping window.
- The Duo pairs a 7.6‑inch inner display, titanium hinge, nano‑texture inner coating and IP68 water resistance with the new A20 Pro 2nm chip and a 4,700mAh battery.
- iOS 27 includes Duo‑specific features such as Split View, saved app pairs, a taskbar for multitasking, StandBy widgets and fold‑aware FaceTime that Apple says justify the form factor.
- Apple sacrificed several iPhone 18 Pro‑class camera and pro features for the Duo, including a dedicated telephoto lens, variable aperture, LiDAR, ProRAW/ProRes RAW and the higher‑res Center Stage front camera.
- Analysts say the Duo could speed foldable adoption over years by showing clear software use cases, but they expect near‑term sales to be limited by high price, tight component supply and competition from mature Android foldables.
