The iPhone Duo is the first-ever foldable iPhone from Apple, featuring a small 5.4-inch exterior screen alongside a very large 7.6-inch foldable screen. The device is made of titanium and is equipped with a nearly crease-less nano-texture interior screen along with an A20 Pro chipset and an IP68 rating. The biggest difference is the operating system, as iOS 27 is optimized in terms of controls, multitasking, and applications layout for a foldable phone. The iPhone Duo is equipped with a dual 48MP camera system, Apple Pencil functionality, MagSafe technology and up to 44 hours of video playback time on the exterior screen. The iPhone Duo is marketed for users who desire a foldable phone but still want to stay within the Apple universe.

The launch of the iPhone Duo is a significant development in the world of smartphones by Apple, where they have made their traditional iPhones more sophisticated by adding a tablet-size 7.6-inch foldable screen to their range of devices. The most notable highlights of this phone include the perfect foldable interface, the potent A20 Pro chip, the almost-creaseless inner screen, the titanium build quality, IP68 rating, and the high battery life. The phone's weight of 254g is a considerable one, but there are still limitations with its current capability of using only two apps simultaneously and using the right side of the interface for controls. However, for iPhone users looking for an advanced foldable device with a large screen, the iPhone Duo will be quite unique.
