Overview
- Apple unveiled the iPhone Duo on Wednesday, Sept. 9 at Apple Park with new CEO John Ternus leading the presentation.
- The Duo uses a book‑style fold with a 7.6‑inch inner display and a 5.4‑inch outer cover screen, a Grade 5 titanium frame, a precision hinge of more than 100 parts and a nano‑textured finish intended to reduce crease visibility.
- Under the hood the phone runs Apple’s A20 Pro 2nm chip, uses a two‑battery split design and is rated for up to about 31 hours of video on the inner screen or 44 hours on the outer screen depending on use.
- Apple has reworked iOS 27 for the Duo to enable Split View, saveable app pairs and other fold‑aware interfaces while bundling on‑device Apple Intelligence and updated Siri features for private local processing.
- The Duo starts at $1,999 for 256GB, opens for preorder on Oct. 16 with shipments beginning Oct. 23, and enters a premium, supply‑limited foldable market after Xiaomi’s recent China‑only 18 Fold announcement.
