iPhone Duo Teardown: A 5/10 Repair Score and a Hinge Mystery
iFixit gave Apple's $1,999 foldable its best foldable repair score yet, then pointed at a hinge support bar as one possible cause of early inner-screen cracks.

What an iPhone Duo buyer gets from this teardown is a foldable that can be repaired, and no answer yet on why some inner screens are cracking in the first days of ownership.
iFixit gave the Duo a provisional 5 out of 10 for repairability, the highest score it has awarded a foldable, with the number held open until replacement parts are actually available. Engadget quotes iFixit calling it "the most repairable folding device yet", while adding that opening it is not for the faint of heart. The Register's summary is blunter: "For a first attempt, Apple has done well." A 5 is still a middling score on iFixit's scale, and the category it leads has set a low bar.
What comes apart easily, and what does not
The good news sits around the edges. According to 9to5Mac's account of the teardown, the Duo carries two batteries, an 11.567 Wh cell under the back glass and a 7.506 Wh cell under the outer display, for 19.073 Wh combined. Both are held by electrically releasable adhesive, which iFixit described as the best battery removal it has seen in a foldable. The outer display lifts out easily, and that matters because several internal repairs start there. The Register adds that the cameras and logic boards were simple to remove, though a full teardown needs five screwdriver types.
The bad news is the inner display and the hinge. The Register reports that freeing the inner screen took heat and a pick and was "far from easy", and that cleaning or replacing hinge parts means removing that display first. Those two parts drove the largest deduction from the score. TechTimes reports Apple's out-of-warranty price for an inner-screen repair at $999, roughly half the phone's $1,999 price, with an estimated three to five hours of labour. It also lists a cover-layer replacement at $49 without coverage and $19 with it.
The cracks, and what iFixit can and cannot say
Fortune reports that some owners of the 7.6-inch inner display, on sale since 23 October, saw cracks along the hinge line within hours, often with a band of stuck white pixels. One Australian owner described a crack after about six hours and fewer than 20 openings. The scale is unclear. Fortune notes that 9to5Mac had counted about ten unique cases, that MacRumors found some circulating images appear to be AI-generated, and that reviewers who tested the phone before launch did not report similar failures.
Apple said it is "aware of an issue impacting the inner display on a small number of iPhone Duo units" and told affected owners to contact AppleCare for a replacement, according to Fortune. The report adds that AppleCare+ is not required, that in-store stock is limited, and that Apple has not disclosed a cause, a fix or a recall.
iFixit built a 3D hinge model from CT scans, teardown footage and Apple patents. Its leading hypothesis, as Engadget and 9to5Mac describe it, is that the central support bar may not drop far enough when the phone closes, pressing on the curved display. The Register quotes the team noting that the damage "isn't right where the display cable passes through the hinge", and Fortune reports that it sits slightly below that crossing, where several edges change how the thin display is supported. iFixit also listed pressure, a trapped particle, repeated bending and a manufacturing defect as possibilities, and said more investigation is needed. It has not reproduced real screen damage from the support bar. That is a hypothesis built on a model.
Dust is a separate worry. Despite the IP68 rating, fine powder reached the hinge in iFixit's test and the hinge "started crunching", per The Register. It took in less powder than recent Samsung and Google foldables did, but the rating clearly does not mean the mechanism is sealed.
What this means for a buyer
Treat the 5/10 as a statement about the parts around the screen, not about the screen. The component most likely to fail in the early reports is also the one iFixit marks down hardest and the one that costs $999 once the warranty no longer covers it. Apple's one-year warranty covers defects from normal use, per Fortune, so a failure in the first weeks should go through AppleCare, not a paid repair.
If you already own one, the evidence supports modest caution rather than alarm: the failures reported so far are a small, unquantified group, and iFixit's own advice, as The Register puts it, is "You'd better baby that screen". If you are deciding whether to buy, wait for two things: iFixit's final score once parts ship, and any Apple disclosure of a cause. Until then, the extra protection plan is a real part of the price of this phone.
