iPhone Duo Passes 300,000 Fold Test in Durability Trial
A durability test conducted by CNET shows the new iPhone Duo surviving over 300,000 folding cycles without visible damage.
On November 7, 2026, the technology news outlet CNET reported on a rigorous durability test performed on the iPhone Duo, Apple's first foldable smartphone, which was released on October 23. To assess the device's longevity, the team developed an automated testing machine dubbed 'Fold-a-Phone' to simulate continuous real-world usage. The device was subjected to a non-stop folding and unfolding process for 24 hours, which was broadcast live on YouTube. According to the report, the iPhone Duo successfully surpassed 300,000 cycles without showing any signs of damage to the hinge mechanism or the foldable screen. The testing apparatus utilized a thin steel wire, less than 0.4 millimeters in diameter, to operate the device, with each cycle taking approximately four seconds to prevent overheating and premature mechanical failure. For residents and travelers in Thailand who may be considering this new device, these results suggest a high level of build quality for the folding mechanism. However, while the initial 300,000-cycle milestone is significant, long-term performance under varying environmental conditions, such as high humidity or dust exposure common in tropical climates, remains to be confirmed through further real-world usage.
