Livestream Puts the iPhone Duo's Folding Hinge Through Thousands of Cycles

A livestream has started a test that anyone interested in foldable phones will want to follow: repeatedly opening and closing a device called the iPhone Duo, with the goal of reaching thousands of folds over several weeks. The broadcast is meant to show, in real time, how the hardware handles the stress that comes with a bending screen and a moving hinge.

The format is the main draw. Rather than waiting for a written verdict at the end of a review, viewers can check in at any point and see the fold count climb. Durability has been the central question for foldables since the first generation of devices, when early models drew attention for creased displays, loose hinges, and dust working its way into the mechanism. Manufacturers have since added stronger hinges, better seals, and tougher display layers. A long, public test is one way to check those claims without relying on a lab's summary.

It is worth being careful about what the stream can prove. A few weeks of mechanical folding is not the same as years of daily use in a pocket, and one unit may not represent every device that comes off a production line. Grit, temperature swings, and accidental drops are harder to reproduce than a repeated bend, so a clean result on a stream does not settle the question of real-world toughness.

The name and the device's details should be read as the livestream presents them, not as an official specification. Anyone watching should look for the fold count, any visible creasing on the display, and whether the hinge still feels consistent near the end of the run. Those moments will say more about the hardware than the headline number.
