iPhone Duo passes 20,000 fold tests in CNET's Galaxy Z Fold 8 showdown

Apple's first foldable smartphone, the iPhone Duo, has surpassed 20,000 folding cycles in CNET's independent durability testing, which pits it against Samsung's Galaxy Z Fold 8. CNET's custom-built "Fold-a-Phone" machine, developed over months, systematically tests the hinge and screens of both devices. The test simulates real-world usage with a four-second open-close cycle, monitoring motor power and using sensors to ensure accuracy. Apple has not disclosed an official folding durability rating, while competitors typically claim 200,000 to 500,000 cycles. CNET will livestream the ongoing test on YouTube, as Apple's entry into the foldable market, seven years after Samsung, could drive broader adoption of the category.
