Overview
- Apple launched the iPhone Duo in China on October 23 with a book‑style inward fold, a 5.4‑inch outer screen, a 7.6‑inch inner screen and the A20 Pro chip, priced from ¥15,999.
- Early teardowns showed a dual‑cell 4,883 mAh battery, a main board labeled A20 Pro plus a C2 baseband, a modular USB‑C port and global eSIM‑only hardware that affects carriers and physical repairs.
- A widely viewed JerryRigEverything durability test found hinge dust ingress and a reverse‑bend sequence that deformed the midframe and cracked the inner 7.6‑inch display, raising concerns about long‑term hinge robustness.
- Apple published official hinge and screen troubleshooting guidance and has begun pushing iOS 27.1 to improve how unadapted apps behave on the Duo, while many popular games still show black bars on the inner display.
- Retail listings and early reseller moves produced short‑term price concessions in some Chinese regions, third‑party makers like PITAKA launched protective covers, and commentators compared the Duo as refined but not clearly ahead of Xiaomi and Huawei foldables.
