iFixit iPhone Duo Teardown Points to Possible Cause of Screen Cracks

Key Points:

• iFixit's teardown of the iPhone Duo revealed that while the device has an IP68 dust and water resistance rating, dust particles entered the USB-C port, speaker mesh, bezel, and hinge, potentially leading to screen damage, though less so than competitors like the Galaxy Z Fold8 and Pixel 11 Pro Fold.
• The cover layer is designed for easy removal and replacement by Apple, with costs of $19 under AppleCare+ and $49 without; the battery uses new adhesive technology allowing for easier removal with a small electrical charge, marking the best battery removal experience for a foldable device so far.
• The outer display is robust and removable, aiding repairability, but the inner display is complex with a 10-layer stack and heavy adhesive, making repairs more challenging; iFixit noted possible display failures may stem from pressure, trapped particles, repeated bending, or manufacturing defects.
• The hinge design, which differs in faulty units, shows stress concentration near critical points where cables and edges meet, possibly causing damage; iFixit’s 3D hinge model and interactive CT scan suggest curved rails and hinge components may contribute to failures, but no definitive cause was identified.
• iFixit gave the iPhone Duo a provisional repairability score of 5 out of 10, the highest among foldables tested, citing the inner display and hinge as major vulnerabilities; this score surpasses the Galaxy Z Fold8 and Pixel 11 Pro Fold, which both scored 4 out of 10.
