iFixit’s teardown of the iPhone Duo highlights Apple’s methods to conceal the fold crease and identifies possible causes for screen and hinge damage, awarding the device a repairability score of 5 out of 10—the highest for a foldable so far.

iFixit has conducted a detailed teardown of Apple's latest foldable smartphone, the iPhone Duo, providing new insights into the device’s internal design and repairability. The site discovered that Apple employs a matte nano-texture cover on the foldable screen, which not only enhances readability in bright conditions but also helps disguise the crease formed by the folding display. Under microscopic examination, iFixit found the screen uses oval-shaped subpixels arranged at different angles, a technique believed to reduce visual artifacts and further mask the crease.

Despite this thoughtful design, iFixit rated the device’s repairability at 5 out of 10. While this score might appear modest, it is the highest rating given to any foldable phone they have reviewed, reflecting some ease in replacing the nano-texture outer layer independently of the underlying OLED panel. However, replacing the OLED itself remains costly and complicated, consistent with the repair challenges typical of foldable devices.

The teardown also revealed some accumulation of dust within the USB-C port, speaker grills, and hinge mechanism. Notably, the amount of internal dust was less than that observed in comparable phones like Samsung’s Galaxy Z Fold8 or Google’s Pixel 11 Pro Fold model.

Addressing user reports of broken screens and cracking hinges on the iPhone Duo, iFixit suggested that the hinge’s sophisticated design may be prone to occasional misalignment during closure. They highlighted an accordion-style cable positioned near the hinge and adjacent to the battery edge, theorizing that pressure concentrated in this area might cause the audible cracking sounds and eventual screen damage some users have experienced. At the time of reporting, Apple had not commented on these findings.

Overall, iFixit’s analysis sheds light on Apple’s approach to optimizing the foldable display experience while illustrating the mechanical complexities that challenge the durability and repairability of foldable smartphones.
