iFixit has completed a teardown of the Apple iPhone Duo, revealing a water-drop hinge design composed of gears, springs, and metal components. The device features a ten-layer screen system with a nano-texture protective layer designed to minimize light reflection and crease visibility. This layer is removable for potential low-cost repairs.
The internal layout marks a shift back to a single-layer motherboard design, last seen in the iPhone 8, to save space for the folding mechanism. The battery utilizes a current-release adhesive system, which iFixit identifies as one of the most repair-friendly battery replacement solutions currently available in the foldable smartphone market.
Dust tests revealed that while the device holds an IP68 rating, particles can still enter the hinge area, causing noise during operation. iFixit noted that this ingress is lower than in competing models like the Samsung Galaxy Z Fold8 or Google Pixel Fold, though it remains a potential factor in mechanical wear.
Regarding reported screen failures, iFixit identified a specific area near the hinge support and flexible cable channels where stress concentration may occur. The team suggests that factors such as dust, manufacturing tolerances, or cumulative mechanical stress could contribute to screen issues, though there is currently no evidence of a widespread design defect.
