Apple's new foldable iPhone Duo, priced between $1,999 and $3,199, introduces a larger 7.6-inch display but comes with several compromises compared to the iPhone 18 Pro lineup. The device foregoes Face ID in favor of a side-button fingerprint sensor and omits the customizable Action button. The camera system is also a notable trade-off, with the Duo featuring a 12-megapixel front-facing camera and lacking a dedicated telephoto lens, though it retains a 48-megapixel ultrawide lens. Battery life is also impacted, offering up to 26 hours of video streaming when unfolded, less than the 38 hours provided by the iPhone 18 Pro Max. The outer screen can serve as a viewfinder for the rear cameras, a feature users have dubbed 'boyfriend-friendly'.
