Apple's iPhone Duo: A Foldable Future or an Expensive Gimmick?

Apple has entered the foldable phone market with the launch of its iPhone Duo, a device that transforms from a standard smartphone into a mini tablet. Priced between £1,999 and £3,199, the iPhone Duo aims to blend the functionality of a phone and a tablet, but questions remain about whether its innovative design is a practical advancement or an expensive gimmick.

Design and Display

The iPhone Duo features a book-style fold, opening to reveal a 7.6-inch inner display, while its outer screen measures 5.4 inches. Despite initial concerns about bulk, the device's design is described as "stunning" in practice. When closed, it adopts a wider, shorter form than a typical iPhone, fitting easily into pockets. A notable design element is the nano-texture finish on the inner screen, which minimizes crease visibility and reduces glare, offering a matte surface that is pleasant to touch and improves usability in bright sunlight. The unfolded device is remarkably thin at 5.2mm. However, a raised rear camera bump prevents the phone from lying flat on a surface when fully open, causing it to rock when typing.

Functionality and User Experience

The outer screen's dock has been relocated to the right-hand side to accommodate its shorter aspect ratio. While Apple's native apps are optimized for this layout, many third-party applications, such as TikTok and Outlook, display distracting black bars on the right side, indicating a lack of immediate optimization for the unique screen size. This could be a significant drawback for users relying heavily on these apps. The right-sided dock also presents usability challenges for left-handed users, particularly when the device is unfolded.

Unlike its recent predecessors, the iPhone Duo utilizes a side-button Touch ID for unlocking, a departure from Apple's long-standing Face ID system. This change may require an adjustment period for users accustomed to facial recognition. The transition between the outer and inner screens is visually smooth, with the front display blurring as the inner screen fades into view. However, the physical act of opening the device requires considerable force and is difficult to do one-handed.

Split View and Camera Capabilities

The device's Split View mode, allowing two apps to run side-by-side, is highlighted as a key strength, facilitating multitasking such as transferring banking information while communicating via messaging apps or referencing a calendar while responding to emails. Despite the convenience, concerns about potential impacts on attention spans due to heavy media multitasking have been noted.

The iPhone Duo is equipped with two rear cameras: a 48MP main camera and an 8MP ultra-wide camera, alongside a 12MP front-facing selfie camera. This camera setup represents a step down from the triple-lens systems found on Apple's Pro iPhones, which have featured three rear cameras since the iPhone 11 Pro in 2019. Nevertheless, the cameras are considered capable of taking decent photos for non-professional users. The device offers multiple ways to take selfies, including using the front-facing camera, the inner camera when unfolded, or the rear cameras with a preview on the outer screen.

Accessories and Price Point

Apple offers two official case designs for the iPhone Duo: the Folio with Kickstand at £129 and a two-part polycarbonate case at £79. Both have drawn criticism for their feel and functionality, with the former described as clunky and the latter as flimsy. Third-party alternatives are suggested.

The considerable price tag of the iPhone Duo, starting at £1,999, positions it as Apple's most expensive iPhone to date. Compared to the iPhone 18 Pro, which starts at £1,199, the Duo is £800 more expensive. However, if viewed as a hybrid iPhone and iPad device, the cost might be more justifiable, as it could be less expensive than purchasing a separate iPad Mini and an iPhone.

Conclusion

While the iPhone Duo introduces appealing features like its matte screen and Split View functionality, it faces challenges. The lack of app optimization for its unique screen size at launch, the reliance on Touch ID over Face ID, and the premium price point are significant considerations. For users who frequently switch between phone and tablet tasks and desire a single device, the Duo could be a viable option. However, for those who prefer separate devices or do not require a larger foldable screen, the standard iPhone 18 Pro or other non-foldable alternatives may offer better value. The device's ultimate success will depend on its ability to overcome these initial hurdles and prove its worth beyond being a novel, albeit expensive, piece of technology.
