This Folding Phone Screen Survived 500,000 Bends — On Camera

The machine folds the phone once every 1.7 seconds. It ran for ten days straight, through a chamber held at minus ten degrees Celsius — the temperature at which earlier foldable screens tended to develop permanent creases.

The published timelapse compresses those 500,000 cycles into eleven minutes. At the end, a technician scrolls a full-white test image across the display: no dead pixels, no bright spots, a hinge that measures 0.3 millimetres looser than on day one.

Rival labs have questioned whether room-temperature tests matter more to real users. The company says it will publish both datasets next quarter.

“The stress test lab published the full timelapse: ten days of non-stop folding at minus ten degrees, and not a single dead pixel.”
