Apple has officially entered the foldable phone market with its first device, the iPhone Duo, which combines titanium durability with a dual-screen experience. The device features an innovative design aimed at delivering a flexible user experience, with a focus on advanced display technologies and addressing traditional challenges in foldable phones such as the crease effect.
Design and Durability
The iPhone Duo relies on a titanium chassis, giving it a weight of 254 grams. The device features a notable thinness when unfolded at 5.2 mm, while its thickness when folded is 11.3 mm. To enhance protection, Apple used a Ceramic Shield 2 layer for the front and Ceramic Shield for the back, along with IP68 water and dust resistance support.
Functionally, Apple omitted Face ID in favor of a Touch ID sensor integrated into the power button, and the Action Button is not available on this model. In a move toward abandoning traditional physical components, the device operates exclusively via eSIM technology without a physical SIM card slot.
Display Experience and Performance
The device contains two OLED displays:
- External Display: Measuring 5.4 inches with a resolution of 1398 x 2034 pixels.
- Internal Display: Measuring 7.6 inches with a resolution of 1878 x 2670 pixels, featuring the use of nano-texture glass which effectively helps hide the screen crease and reduce reflections.
Both screens support ProMotion technology with a refresh rate of up to 120 Hz, along with the Dynamic Island located in the upper corner of the internal screen. The device is powered by the A20 Pro processor (featuring a 6-core CPU and a 7-core GPU), and is available in storage capacities starting from 256 GB up to 2 TB. However, it was noted that the device may experience a slight temperature rise during intensive use compared to the iPhone 18 Pro model.
Camera System and Battery
The rear system houses two 48-megapixel cameras (the main with an f/1.6 aperture, and the ultra-wide with an f/2.2 aperture), with an optical zoom capability equivalent to 2x. As for selfies, the device contains a 12-megapixel camera on the external screen, and an under-display hidden FaceTime camera on the internal screen with an f/1.8 aperture, though its quality is relatively lower.
Regarding power, the battery provides up to 24 hours of daily use and supports 60W fast charging, where 50% of the battery can be charged in approximately 20 minutes.
What Changes Practically?
The iPhone Duo represents Apple's attempt to merge productivity with portability, but it imposes some compromises. While the large screen provides an excellent experience for gaming and content viewing, App Optimization remains a challenge, as some apps do not display ideally when using the large screen or splitting it. Furthermore, abandoning the dedicated Telephoto camera and relying on high-quality digital zoom may not satisfy professional users who are accustomed to the Pro category.
