Overview
- The iPhone Duo, which launched on October 23, is Apple’s first foldable with a 7.6‑inch inner screen, a 5.4‑inch outer screen and an A20 Pro chip, and it went on sale with a China starting price of ¥15,999.
- A high‑profile durability test by JerryRigEverything showed the inner display cracked after repeated reverse bending and found dust ingress into the hinge, and multiple teardown videos confirmed midframe deformation under stress.
- Users in the United States, India and China have reported inner‑screen cracks near the hinge after limited use, and some Apple Stores have been replacing affected units where replacement stock is available.
- Apple published hinge troubleshooting guidance that says these faults cannot be fixed by software and advises component replacement, while independent teardowns revealed a dual‑cell 4,883 mAh battery, an A20 Pro with C2 baseband, modular USB‑C and eSIM‑only models.
- Market and ecosystem responses include local price reductions in parts of China, third‑party protective cases that may trap dust, and app makers shifting to Apple’s compatibility modes with an iOS 27.1 update expected to enable fuller foldable display support.
