iPhone Duo Reportedly Facing Production Problems Ahead of Launch

The iPhone Duo is reportedly facing production difficulties ahead of its October launch, with early output expected to be limited. A person said to be close to Foxconn's supply chain told China's Jiemian News that final assembly yields for Apple's first foldable iPhone were only slightly above 60% as of September 17. The source said that, under Apple's current quality standards, it could take another six months to a year for the assembly line to reach a mature yield. According to the source, Foxconn is repeatedly adjusting equipment, assembly processes, and production settings as it makes the ‌iPhone Duo‌ at scale. The source also said suppliers were waiting to see whether Apple would ease any quality requirements to accelerate production. The problems apparently extend beyond final assembly. Jiemian News said Samsung Display's foldable OLED panels and hinge components had experienced low yields, delayed deliveries, and design changes. Delays in those parts leave the assembler less time to tune its production line. The publication added that Apple tested Liquid Metal for some hinge parts before reassessing the approach ahead of mass production. Apple says its hinge contains more than 100 components and has a 3D-printed cover. A supply chain source also told Jiemian News that Apple's global stocking target for the ‌iPhone Duo‌ in 2026 is approximately six million to eight million units. The publication compared that figure with typical shipments of 20 million to 30 million units over a full product cycle for an individual iPhone Pro or Pro Max model. A separate retail source said Apple's sales guidance exceeds five million units. In another report, MyDrivers claims that one of the device's contract manufacturers asked Apple to choose between prioritizing yield and increasing output. The site suggested that running the production line harder could produce more saleable phones, but with the side-effect of more defective units and higher scrap costs. Apple unveiled the iPhone Duo on September 9. Pre-orders are scheduled to begin October 16, with availability following on October 23. The ‌iPhone Duo‌ starts at $1,999 in the United States.
