Display

The Duo design features a 5.4-inch outer display and a 7.6-inch inner display when unfolded. The device uses a book-style folding design. The two displays have a consistent aspect ratio, allowing content to transition between the folded and unfolded configurations.

The inner display also incorporates a camera beneath the display for FaceTime.

The iPhone Duo uses Apple's C2 cellular modem. The device also includes Apple's N1 wireless networking chip, which supports Wi-Fi 7, Bluetooth 6 and Thread.

Battery

The iPhone Duo uses a dual-battery system. Apple states that the device provides up to 24 hours of battery life with the use of the two displays. The battery can charge to 50 percent in approximately 20 minutes using a compatible fast charger.

Software

The iPhone Duo will be shipped with iOS 27.1 on release.

Accessories

The iPhone Duo is the first iPhone to support the Apple Pencil (USB-C), although it will not be supported at launch.
