Overview
- Apple opened iPhone Duo preorders on October 16 and will begin retail sales in select markets on October 23, offering a book‑style foldable with a 7.6‑inch inner and 5.4‑inch outer 120Hz displays, A20 Pro chip, eSIM‑only design, and China pricing from ¥15,999.
- Supply‑chain reports say early demand exceeded expectations and Apple raised its 12‑month shipment target from 9.7 million to 14 million units, but first‑wave production is small at about 2 million units globally and under 200,000 units for China with assembly yields just above 60 percent.
- Apple published iOS 27.1 SDK support, an iPhone Duo simulator in Xcode 27.1, and the App Store 'Made for iPhone Duo' badge to encourage optimizations, and dozens of major apps including Tencent QQ and 高德 have issued Duo‑specific updates to fix black‑border and layout issues.
- Early hands‑on reviews praise the hidden under‑display camera for unobstructed screen look but report clear image quality limits for that 4MP sensor, while several reviewers noted device heat under heavy use and mixed performance during sustained workloads.
- Retail rollout includes new in‑store displays and limited walk‑in availability, and the combination of tight stock, ongoing app updates, and reported imaging and thermal tradeoffs will determine whether the Duo converts strong interest into sustained sales.
