The iPhone Duo may be facing a rocky start on the production line. A source described as close to Foxconn’s supply chain told China’s Jiemian News that the foldable’s final-assembly yield sat only slightly above 60% as of September 17, and that under Apple’s current quality standards, it could take another six months to a year for the line to reach a mature yield. Foxconn is said to be continuously adjusting its production equipment, assembly processes, and settings to raise that number.
The trouble reportedly isn’t confined to final assembly, either. Jiemian News says Samsung Display’s foldable OLED panels and the device’s hinge components have separately dealt with low yields, delayed deliveries, and design changes, which in turn cuts into the time Foxconn has to fine-tune its own line. The hinge is one of the more complex parts of the design Apple has said it contains more than 100 components, including a 3D-printed cover and the report adds that Apple had experimented with Liquid Metal for parts of the hinge before reconsidering the approach ahead of mass production, something Apple hasn’t confirmed either way.
These production issues line up with concerns about how many units will actually be available:
| Source | Estimate |
| Supply-chain source (Jiemian News) | ~6–8 million units globally in 2026 |
| Retail source | Sales guidance above 5 million units |
| Analyst Jeff Pu | ~6 million units in 2026, down from a prior 7 million estimate |
| Typical iPhone Pro/Pro Max | 20–30 million units over a full product cycle |
Separately, MyDrivers reports that one of Apple’s contract manufacturers asked Apple to choose between prioritizing higher production output or higher yield since pushing the line faster can mean more finished units, but also more defects, scrap, and cost. That tradeoff may be why Apple appears to be leaning toward improving yield first rather than ramping volume aggressively.
None of this points to a delayed launch so far. Apple’s pre-order date of October 16 and availability on October 23 remain in place, alongside the $1,999 starting price. If the reports hold up, the more likely outcome is a tight, constrained launch rather than Apple pushing the date back.
