iFixit's teardown of Apple's first foldable, the iPhone Duo, awarded the device a provisional repairability score of 5 out of 10 - the best mark the repair outlet has given any foldable phone to date. But the analysis also flags a costly inner-display replacement and possible hinge vulnerabilities tied to early reports of screen failures.
Easier access to batteries and components
iFixit found that Apple organized the iPhone Duo's internals so that cameras and charging hardware can be reached without removing unrelated parts first, a departure from the layered disassembly typically required on rival foldables. The phone's two batteries, with a combined capacity of 19.1Wh, use electrically releasable adhesive similar to Apple's standard iPhones, letting technicians loosen them with a small electrical charge rather than pulling or flexing them. Metal enclosures around each battery add further protection, and iFixit called the process the best battery-removal experience it has seen in a foldable. The outer display can also be removed without damaging its frame, and Apple has published an official repair manual, though parts availability is still being evaluated. For comparison, the Samsung Galaxy Z Fold8 and Google Pixel 11 Pro Fold each scored 4 out of 10 in iFixit's testing.
A replaceable layer to fight the crease - at a price
To soften the visible crease common to folding screens, Apple applied a nano-texture surface layer containing microscopic rounded structures that scatter reflected light; iFixit confirmed that removing this layer makes the crease far more noticeable. Oval-shaped subpixels arranged at varying angles may also help reduce reflection patterns. Crucially, this cover layer can be replaced separately from the OLED panel beneath it, though the procedure requires specialized tools and precise alignment rather than a simple peel-and-stick swap. Apple's published pricing, cited by iFixit, puts that cover-layer replacement at $49 without AppleCare+ or $19 with coverage - a sharp contrast to the $999 cost of replacing the entire inner display without AppleCare+.
Hinge pressure points and dust exposure under scrutiny
iFixit examined reports of unusual noises and bright lines appearing on some iPhone Duo units' displays, in certain cases within hours of purchase. Using teardown footage, patents, CT scans and a 3D model, researchers identified a possible pressure point near the central hinge support, theorizing that an internal component may not always retract fully when the phone closes. iFixit stressed this remains a theory, not a confirmed defect, and there isn't enough data yet to know how widespread the issue is. Separately, a fluorescent-powder test showed the iPhone Duo collected less visible particulate than the Galaxy Z Fold8 and Pixel 11 Pro Fold, though some powder still reached moving hinge components and produced an audible crunching sound - a result iFixit notes falls short of a formal dust-resistance certification test.
A stronger start, but durability remains unproven
The teardown suggests Apple made real repairability gains for a first-generation foldable, particularly around battery removal and the replaceable screen cover. But the steep cost of a full inner-display replacement, combined with unresolved questions about the hinge, means prospective buyers should weigh long-term repair costs alongside the purchase price.
