iPhone Duo: A Look at the Real-World Capabilities of Apple’s Foldable
One week after launch, we evaluate the performance and potential of Apple's first foldable device.

A week has passed since the iPhone Duo launched, and its real-world performance is becoming clear. As Apple’s first attempt at a foldable smartphone, the device has generated significant interest. While reviews have been mixed, it remains an intriguing development for many users.
Screen Issues and Reality
Recent reports have highlighted white lines appearing on the screen, a common concern for foldable devices. Apple states that this defect affects only a small number of units. It is important to note that the issue typically manifests shortly after purchase. If your iPhone Duo has functioned without issue during the first week, it is highly likely that your device is not affected by this defect.
Design and Daily Use
The external screen, despite its compact size, has proven quite practical. It is ideal for checking notifications, sending quick replies, and navigating apps. When unfolded, the device provides a full-sized screen designed for multitasking. Watching videos in portrait mode and running multiple apps simultaneously is particularly comfortable.
Regarding security, the Touch ID fingerprint sensor is easily accessible, and the Apple Watch unlocking feature is as fast and convenient as Face ID. App optimization is still an ongoing process, though it improves daily. The 'Wider' extension for Safari allows webpages to expand fully to the edges of the external screen.
Battery and Camera
The iPhone Duo’s battery life sits between the iPhone 18 Pro and Pro Max, meaning it easily lasts through the day for the average user. However, the camera system requires some compromises. Those who rely on a telephoto lens may find its absence noticeable, as the Duo’s cameras offer only basic functionality.
Despite some shortcomings, the iPhone Duo has brought new life to the Apple ecosystem. It is not just a smartphone, but a new form factor that developers and users are gradually adapting to. If you are already using an iPhone Duo, sharing your experience is valuable, as user feedback will define the future of this series.
