Apple’s foldable iPhone output stuck at hundreds a day before Wednesday unveiling

Apple ↘ 0.52% is struggling to ramp up mass production of its first foldable iPhone just days before the device is expected to be unveiled at a launch event on Wednesday, September 9. Daily output stood at only a few hundred units as of late August, far short of the tens of thousands needed to meet initial demand, according to a Nikkei Asia report cited by multiple Korean outlets.sedaily+1

Quality Standards Slow the Ramp-Up

The bottleneck stems from Apple's exacting quality requirements. According to supply chain sources cited by Nikkei Asia, Apple added an extra round of trial production in August before beginning full mass production, driven by concerns over surface flatness and hinge performance. The company demands testing under more extreme conditions, a higher number of fold cycles, and greater screen flatness than its competitors — standards that have created yield problems throughout the development process.sedaily

The foldable iPhone's road to production has been rocky for months. Engineering setbacks surfaced as early as April, when Reuters reported that development issues were "more complex and taking more time to resolve than Apple had expected". In May, leaker Fixed Focus Digital pointed to surface-mount technology yield failures during pre-assembly. By August, the same leaker said those earlier hurdles had been "overcome" and the device remained on schedule for a September launch — though the latest reports suggest the ramp-up remains slower than planned.reuters+3

A Foldable Showdown With Samsung

The launch will pit Apple directly against Samsung, which unveiled its Galaxy Z Fold8 at an Unpacked event in London on July 22. Samsung's device starts at $1,899 with a 7.6-inch inner display, while Apple's foldable is rumored to feature a 7.8-inch crease-free inner screen and a 5.5-inch cover display at a starting price north of $2,000.cnet+2

Analysts see Apple's advantages in its iPad app ecosystem, in-house silicon, and the AI model integration built into iOS 27, which will let users choose between ChatGPT, Claude, or Gemini behind Siri. Apple's entry is also expected to reverse a decline in the broader foldable market, with analysts projecting 12.6 percent category growth this year.yellow+1

Limited Supply Expected at Launch

Forbes reported that the foldable iPhone will likely be announced on September 9 alongside the iPhone 18 Pro and iPhone 18 Pro Max, with sales potentially beginning September 18 — though availability may be "very limited". Phone Arena noted the unveiling's excitement "may be overshadowed by limited availability". If Apple cannot accelerate production, supply chain sources warn there is "a strong chance inventory will be short when sales begin".forbes+2
