Overview
- The iPhone Duo uses a passport-style dual-display design with a 5.4-inch outer screen and a 7.6-inch inner foldable OLED and is built from grade‑5 titanium with Ceramic Shield and a matte nano-texture inner display.
- Apple fitted the Duo with the A20 Pro chip and 12GB of RAM and added foldable-specific cooling, including a vapor chamber and a hinge heat pipe, to sustain high performance.
- Apple made deliberate hardware trade-offs by removing Face ID in favour of Touch ID in the side power button, fitting two 48MP rear sensors but no dedicated telephoto lens, and selling the phone as eSIM-only.
- Reviewers report real-world battery results of about 6.5 hours of active screen time under heavy use and praise the hinge and build quality while noting a learning curve for repositioned controls and limited third-party app optimisation.
- Apple is positioning the Duo as a premium halo product with high prices such as S$3,099, constrained early inventory due to low panel and hinge yields, and near-term software additions including Apple Pencil support expected via iOS 27.2.
