Apple's first foldable iPhone takes some getting used to. At first, the iPhone Duo's compact shape and smaller outer screen felt unfamiliar, and unfolding it didn't seem essential. After a few days, however, its larger display and flexible design began to feel more natural.
A Foldable Design Built for Everyday Use
The titanium Duo has a 5.4-inch outer display that opens into a 7.6-inch screen. Its hinge supports several viewing positions, making it possible to prop the phone up for video, workouts or hands-free photos. The inner display has a matte finish, while the crease is difficult to notice when viewed straight on.
Apple has also changed the familiar iPhone layout: volume buttons sit at the top, and the lock button incorporates Touch ID instead of Face ID. The larger screen is useful at home, though using it one-handed while moving around can feel awkward.
Performance, Cameras and Battery
Everyday tasks felt responsive, and switching between the two displays was smooth. The Duo's split-screen setup makes multitasking and video editing more convenient, while its A20 Pro chip matches the iPhone 18 Pro line. Its 48-megapixel rear camera takes capable photos, but lacks some of the advanced controls and zoom features found on the Pro models.
The foldable form also enables features such as Smart Take, which automatically captures a photo when people are in position, and a preview mode that lets subjects check their framing. Two batteries power the device; during testing, it lasted through a full day of typical use.
Who Is It For?
Priced at $1,999, the iPhone Duo offers a polished foldable experience and a roomy screen for video, browsing and multitasking. Its camera is not as versatile as the Pro line, and its size can make on-the-go use less straightforward. People who value a simple, pocketable phone may prefer a conventional design.
The Duo shows how foldable phones could make one device more adaptable, though their long-term appeal will depend on balancing larger screens with everyday comfort and value.
