What to Consider Before Buying
- Foldable usage scenarios: The outer display is suited to quick interactions, while the 7.6-inch inner display is better for multitasking, reading, and video.
- First-generation durability: Apple has shared materials and hinge details, but long-term crease behavior, dust resistance, and repair costs still need real-world data.
- App layout support: iOS 27.1 redesigns interactions for different postures, but third-party app adaptation will still affect the large-screen experience.
- Storage is a variant attribute: The iPhone Duo product name does not include storage; 256GB, 512GB, 1TB, and 2TB should be managed separately in each variant record.
