Overview
- Apple introduced the iPhone Duo at its Sept. 9 event and said preorders begin October 16 with shipments on October 23, starting at $1,999 for 256GB.
- The Duo folds open to a 7.6‑inch inner display and has a 5.4‑inch outer screen, uses a titanium frame, runs iOS 27.1, and Apple says it is the thinnest iPhone when unfolded.
- To fit the hinge and thinner body Apple removed Face ID, the Action button, and a dedicated telephoto camera and moved Touch ID into the side button, which reduces camera, biometric, battery, and charging capabilities versus iPhone 18 Pro models.
- Apple confirmed the phone will support the USB‑C Apple Pencil only and that Pencil functionality will arrive after launch, and it also includes MagSafe but many existing MagSafe accessories may not fit or work as expected.
- Analysts forecast about 5 million Duo shipments in 2026 and Apple shares and some supplier stocks rose after the announcement, but firms warn inventory limits and first‑generation trade‑offs may temper near‑term sales.
