Apple today introduced iPhone Duo, the first foldable iPhone. Opened, it is the thinnest iPhone ever, with a 7.6-inch inner display featuring a nano-texture finish that minimizes glare. Closed, the 5.4-inch outer display delivers 90 percent of the screen area of iPhone 18 Pro in a compact design. Both displays share the same aspect ratio for seamless content scaling.

The device is built with a precision hinge for smooth use. Powered by the new A20 Pro chip, it includes an advanced thermal system with a vapor chamber and dual-battery architecture for all-day life. The camera system enables unique folding photography, while iOS 27 adapts to versatile interactions.

Apple Intelligence and Siri AI integrate personal context for powerful assistance. iPhone Duo comes in star white and night sky, with pre-orders starting Friday, October 16, and availability on October 23.
