Five Pro-Tips to use the iPhone Duo

 

The iPhone Duo is Apple's first foldable smartphone, launched in September 2026, marking the company's long-awaited entry into the foldable segment. It features a book-style folding design, runs on the same A20 Pro chip as the iPhone 18 Pro, and positions itself as a thin-and-light productivity device, though its pricing sets a new record for the iPhone lineup.

Make full use of split screen multitasking to boost your productivity. The Split View that iOS 27 brings to the Duo is the core value that separates this device from a regular iPhone, so pair Mail with Calendar or your browser with Notes, and enter work mode the moment you unfold rather than using it like just another big phone.

If you use a third party case, remember to enable the Shift Left Edge display setting. This hidden feature roughly doubles the width of the left bezel on the outer screen, ensuring that iOS back swipe gestures remain smooth and accurate even when a case slightly encroaches on the screen edge.

Use the outer display for quick, lightweight tasks. The 5.4 inch cover screen is more than enough for replying to messages, checking notifications, or grabbing a quick shot, so you do not need to unfold the device for every small task, which saves battery and reduces wear on the hinge.

Combine Touch ID with Apple Watch unlock. The Duo has no Face ID, but the side mounted Touch ID works in both forms, and pairing it with Apple Watch unlock delivers a nearly seamless authentication experience, especially when you are wearing a mask or your hands are wet.

Take advantage of the nano-texture inner screen for writing. The nano-texture coating on the inner display not only cuts glare but also provides a paper-like writing feel, so with Apple Pencil support, taking notes and annotating documents on the Duo feels noticeably better than on standard glass.
