Overview
- The iPhone Duo uses a book‑style hinge with a 7.6‑inch inner display and a 5.4‑inch outer display and is marketed as Apple’s thinnest unfolded iPhone.
- Both screens are Super Retina XDR panels with ProMotion, Always On, a nano‑texture finish and a hidden FaceTime camera under the inner display.
- Apple removed Face ID and a dedicated telephoto lens to meet the Duo’s thin profile and placed Touch ID in the side button for biometric access.
- The device will be sold in two colourways, Star White and Night Sky, with UK pricing reported to start at about £1,999 and rise with storage.
- Suppliers and analysts expect limited early supply because foldable panels and hinge assemblies have low initial assembly yields, so Apple plans a tight, staged rollout and delayed support for some accessories such as Apple Pencil.
