A tech testing channel subjected Apple's iPhone Duo to 10,000 open-and-close cycles, finding the titanium hinge stayed smooth while the central display crease became more pronounced.
Apple's recently launched iPhone Duo was put through an extensive durability test by tech testing channel Mediastorm, which opened and closed the device 10,000 times. The test reportedly showed that the titanium hinge continued to operate smoothly throughout the process. However, the central display crease became noticeably deeper and more visible after repeated folding. The test was featured by Mashable Me and published on October 24, 2026.
