Apple entered the foldable device market with the release of the iPhone Duo, starting at $1,999 and scaling up to $3,199 for the two-terabyte storage configuration, Mashable reported.
The device features an inner matte screen equipped with a glare-reducing nano-texture finish. It runs on the A20 chip, which is also used in the iPhone 18 Pro and Pro Max models.
iPhone Duo Features a Thin Folding Design and Stylus Support
The iPhone Duo adopts a passport-style folding mechanism with rounded corners, measuring thinner and lighter than Apple’s iPad lineup. The inner display supports stylus input from the Apple Pencil, priced at $79.
Senior Editor Stan Schroeder evaluated the inner panel during testing. “The nicest phone display I’ve ever seen,” said Schroeder, who described it as “crisp, sharp, [and] beautiful to look at; it’s downright addictive.”
A20 Chip Powers Multitasking Despite Camera and Battery Limits
Equipped with the A20 chip, the foldable handles split-screen multitasking and graphics-heavy tasks without lag. Battery longevity remains limited compared to the standard iPhone 18 Pro models, though it meets typical usage expectations for the foldable category.
Photography features lack a telephoto lens setup. The embedded FaceTime camera on the inner folding screen received negative feedback from early reviewers.
“Bad,” Schroeder told Mashable regarding the inner camera quality.
Inner Screen Fractures and Delivery Delays Affect Early Users
Early users reported instances of inner screen fracturing soon after purchase, an issue receiving attention across social media platforms. Apple said that the defect remains restricted to “a small number” of units and advised affected purchasers to request replacements through AppleCare.
Sister publication CNET mounted a test unit inside a mechanical folding apparatus to evaluate structural integrity. The machine tests the hinge mechanism by folding the device 900 times every hour.
High demand caused extensive delivery delays upon release. Customers placing orders through the Apple Store face waiting periods extending into the opening weeks of 2027.
