CNET answers 16 questions on folding the iPhone Duo 200,000 times

CNET is stress-testing Apple's iPhone Duo by folding it over 200,000 times with a custom machine, livestreaming the process to assess durability. The test aims to determine how the foldable phone holds up under realistic conditions. The Fold-a-Phone machine, built independently without Apple's involvement, opens and closes the device every four seconds, 24/7, in a cool room to prevent heat damage. CNET designed it to mimic human use, unlike a harsher 2019 clapper-style tester, and will compare results against competitors like Samsung's Galaxy Z Fold 8. The testing is ongoing until the phone breaks, with manual checks every 100,000 folds. CNET notes the machine should outlast the phone, and while results will inform durability comparisons, they do not directly advise whether consumers should buy the iPhone Duo.
