Dissecting the iPhone Duo: Why is Apple’s First Foldable Failing?
A New Record for Repairability, With Questions Remaining
Apple’s first foldable smartphone, the iPhone Duo, has become the focus of the tech world. The renowned repair platform iFixit has conducted a detailed teardown of the device to understand its complex internal mechanism. The smartphone received a 5 out of 10 on the repairability scale. While this figure may seem low, it is the best result ever recorded for a foldable smartphone.
The Secret of the Screen Crease
One of the most significant concerns for users is the visibility of the screen crease. iFixit observed that Apple employed several clever methods to address this issue. A special matte "nano-texture" is applied to the screen surface, which not only improves readability in bright sunlight but also makes the crease less noticeable by diffusing light.
Microscopic examination revealed that the screen's subpixels are oval-shaped and arranged at different angles. This design choice aims to reduce image artifacts and visually mask the crease in the middle of the display. Notably, this nano-coating can be replaced without damaging the OLED panel, which helps reduce long-term costs for the user.
Why Are Hinges and Screens Breaking?
Despite these technological advancements, reports of cracked screens and damaged hinges on the iPhone Duo have already surfaced. iFixit’s analysis suggests the problem may lie in the device's internal structure. The hinge mechanism is exceptionally complex, and there is speculation that in some cases, it does not fold perfectly flat.
Furthermore, an "accordion-style" cable runs through the exact part of the hinge that experiences the most stress, located near the edge of the battery. Experts believe this cable may be creating additional pressure, causing a "loud click" that eventually leads to screen failure. Regarding dust resistance, the iPhone Duo performed better than competing models, though small amounts of dust were still detected in the USB-C port and speakers.
What Does This Mean for Users?
Foldable phones are becoming increasingly popular, yet they remain difficult and expensive to repair. While the iPhone Duo is one of the most "repairable" foldable models on the market, Apple's strict restrictions and high component costs mean users should handle the device with extreme care. In regions where the network of authorized service centres is still developing, the availability of warranties and professional service remains a top priority when considering such a purchase.
