The iPhone Duo offers a unique foldable experience with notable hardware limitations and high pricing

The iPhone Duo is Apple's first foldable smartphone, featuring a 7.6-inch inner display and a 5.4-inch outer screen with a matte nano-texture layer that minimizes reflections and creases. While the device introduces multitasking capabilities like split-screen functionality and a seated mode for media consumption, it lacks several professional-grade features found on the iPhone 18 Pro Max, such as ProRAW, ProRes, Apple Log, and variable aperture. The device is powered by the A20 chip and supports the Apple Pencil USB-C edition, though it lacks pressure sensitivity. Despite its premium $1,999 price tag, the Duo features a 5,000mAh battery, which performs comparably to the 18 Pro Max in daily use. The build quality utilizes a titanium frame, but the outer ceramic shield is prone to scratching. Furthermore, the device has faced reports of screen cracking along the hinge, and it lacks Face ID, relying instead on a side-mounted Touch ID sensor. The Duo is eSIM-only and features an under-display selfie camera, which provides lower image quality compared to traditional front-facing sensors.
