iPhone Duo Hinge Starts Failing After 440,300 Folds, No Longer Opening Fully Flat

Summary
Around 440,300 folds, the iPhone Duo stopped opening completely flat on CNET’s test rig, leaving the screen about 5 to 10 degrees short of fully open.
Sensor data showed the hinge began degrading near 390,000 folds, with weaker opening force and motion gradually worsening until the phone could no longer finish opening before the next close cycle.
The device still works, holds other positions and shows no cracking, blackout or sensor failure, so the issue does not yet meet the test’s formal failure conditions.
At 100 folds a day, the wear equates to nearly 12.5 years of use, and Apple has not disclosed a durability rating; CNET plans to keep testing to see how far the hinge deteriorates.
