Watch a Live Test Fold the iPhone Duo Thousands of Times

A live stream is set to put a folding iPhone through a punishing durability test, opening and closing the device thousands of times while viewers watch. The listing names the iPhone Duo as the device under test. The premise is simple: how much wear can a foldable hinge and display take before something gives out?

Durability has followed foldable phones since the first models shipped. Repeated folding can wear down hinges, strain the crease in the screen, and loosen the seals that keep dust out. A long test run is one of the few ways outside buyers can see how a device holds up over time, rather than judging it from a single demo.

The listing offers few other details, including the test setup, the exact fold target, or how the results will be judged. Anyone interested in the outcome can tune in when the stream goes live.
