After 32,000 Folds, iPhone Duo’s Hinge Serves up a Big Surprise
Tech journalist Joanna Stern and hardware designer Aron Cohen created a custom machine called Hingey to test the iPhone Duo’s hinge durability by folding it over 32,000 times automatically. The test aimed to evaluate if the hinge would loosen or degrade through repeated use, addressing common folding phone concerns such as screen creases and hinge wear. Despite aggressive stress testing, the iPhone Duo’s hinge maintained its performance, demonstrating Apple’s complex engineering with over 100 components to ensure smooth opening and closing.
