CNET Durability Test: Apple's First Foldable iPhone Duo Survives 457,000 Folds, Hinge Wears and Loosens / No Cracks on Screen
IT Home, November 14 news: After tech media CNET concluded its 15th day of live streaming yesterday (November 13), Apple's first foldable iPhone Duo has undergone 457,053 folds. It is still operational, with no cracks visible on the screen, but the hinge has shown obvious signs of wear.
IT Home attaches the relevant screenshot below:

Testers said the change first appeared at around 390,000 folds, when the hinge could be felt becoming loose. After the count increased to about 440,300 folds, the phone could no longer fully unfold before the machine's next fold, falling 5 to 10 degrees short of full unfolding, and the previously distinct feeling of opening and closing into place no longer appeared.
This folding test is still continuing. The termination conditions set by the team include the device losing power, the sensor failing to correctly recognize the screen state, and the screen going black, among others. Calculated at 100 folds per day, 450,000 folds is equivalent to more than 12 years of folding.
