Apple's first foldable phone is reportedly struggling to clear the company's own quality bar on the assembly line before its October launch.
A supply-chain source told China's Jiemian News that final assembly yields for the iPhone Duo were just above 60 percent as of September 17, and could take another six months to a year to reach Apple's usual maturity level. Foxconn is reportedly still adjusting equipment and assembly settings, partly because Samsung Display's foldable OLED panels and hinge components arrived late and needed their own design changes. Apple reportedly tested a Liquid Metal hinge component before backing away from it ahead of mass production; the hinge that shipped has more than 100 parts and a 3D-printed cover. Apple's 2026 stocking target is reportedly 6 million to 8 million units, well below the 20 million to 30 million a Pro or Pro Max model typically sells across a full cycle, and one contract manufacturer has reportedly asked Apple to choose between higher yields and higher output.
That tradeoff is the real story here. A phone shipping in the single-digit millions in its first year isn't a mass-market bet, it's a controlled experiment Apple is charging $1,999 to run, with early buyers effectively testing a hinge design Apple itself was still second-guessing months before launch.
Samsung has spent years working through exactly this kind of foldable yield problem, and its early Galaxy Fold models had well-documented growing pains of their own. Apple is entering that fight with a supply chain that, by its own supplier's account, is still arguing over whether to prioritize quality or volume.
