iPhone Duo screen may crack after about 75,000 folds, tests show
Gizmodo reported that independent testing found the iPhone Duo’s inner display can develop cracks after roughly 75,000 hinge folds, a durability figure Apple has not publicly disclosed. Earlier tests had shown mixed durability results: iFixit’s teardown highlighted dust ingress in the hinge and gave the device a repairability score of 5 out of 10; JerryRigEverything documented dust entry and screen damage in its durability assessment; CNET began a systematic folding test to compare the Duo with Samsung’s Galaxy Z Fold 8; The Verge observed that after 11,500 folds the crease became more visible while the hinge remained solid; Joanna Stern and a hardware designer each folded the phone over 32,000 times with a custom rig, noting only a slight increase in hinge stiffness. The device’s launch sparked strong demand and mixed reviews.
