Apple iPhone Duo

A new iPhone enters the fold

The Apple iPhone Duo is Apple’s first foldable smartphone, announced in September 2026 and set for release on October 23, 2026. It features a book-style design that opens to a large 7.6-inch Super Retina XDR inner display with a nano-texture finish to minimize glare and crease visibility, while the compact 5.4-inch outer display provides nearly the screen area of an iPhone 18 Pro when closed. Powered by the A20 Pro chip with 12GB of RAM, it offers dual-battery architecture for strong endurance (up to 31 hours of video on the inner screen and 44 hours on the outer), a 48MP Fusion main camera with ultrawide support, and fold-optimized iOS experiences for multitasking and new camera modes.

Key Features

Large Foldable Dual Displays

The iPhone Duo opens to a 7.6-inch Super Retina XDR inner display with a nano-texture finish that reduces glare and crease visibility. When closed, the 5.4-inch outer display offers a compact yet usable screen that maintains visual continuity with the same aspect ratio.

Precision Foldable Design

Built with a durable grade 5 titanium frame and a refined precision hinge, the device feels smooth and solid with every open and close. It achieves an impressively thin 5.2mm profile when unfolded while remaining pocketable when closed.

A20 Pro Performance

Powered by the same A20 Pro chip found in the iPhone 18 Pro models, along with advanced thermal management, the Duo delivers strong processing power for multitasking, gaming, and AI features. A dedicated display engine helps drive both screens efficiently.

Dual-Battery Endurance

A dual-battery architecture places high-capacity cells on each side of the fold. This design supports up to 31 hours of video playback on the inner display and up to 44 hours on the outer display for reliable all-day use.

Advanced Camera Experiences

The 48MP Fusion main camera and ultrawide sensor deliver high-quality photos and video, with optical-quality 2x zoom. The foldable form factor enables unique new shooting modes and creative camera experiences not possible on traditional iPhones.
