The iPhone Duo that sold out in one minute exposes Apple's foldable screen production capacity shortfall

[[**iPhone Duo pre-orders sold out in one minute but face severe shortages, with shipping already pushed back to January 2027. Three major bottlenecks—hinge precision, panel yield, and assembly yield—have limited the first batch to just over 100,000 units, with full-year shipments expected at 5-6 million units. Apple is charging straight to second place in the global foldable market with about a 25% share, putting Huawei under pressure to defend its position.**

**Key Points**

**1. Demand is red-hot but production capacity is severely constrained**

iPhone Duo pre-orders sold out across all channels within one minute, with over 3 million reservations on JD.com, while the first batch supplied fewer than 200,000 units. Shipping on the official website is already scheduled out to January 2027, and the U.S. market is equally tight. Bloomberg reporter Mark Gurman directly called it a "big mistake" for Apple to insist on launching despite knowing supply was constrained.

**2. Three process bottlenecks—hinge, panel, and assembly—are choking production capacity**

Apple's self-developed hinge contains 80-100 precision parts with tolerance requirements of 0.01 mm; industry yield for foldable OLED panels is below 70%; and as of September 17, whole-device assembly yield was only just over 60%, far below the 97%+ level of mature models. Ming-Chi Kuo expects third-quarter shipments of only 500,000-1 million units.

**3. Foldable market growth is slowing, yet Apple surpasses Huawei in share in its first year**

TrendForce expects global foldable shipments to grow only 0.5% to 20.2 million units in 2026, with the Android camp declining over 20% year on year. Apple rises to second place with up to 6 million units and a 25% share, while Huawei slips to third with about 5 million units and a 22% share—but Apple's share relies on existing users upgrading rather than accumulated reputation.

**4. Huawei defends 5 million units amid Android decline and cost pressure**

Huawei needs to hold 5 million units in shipments against a backdrop of the Android camp shrinking by 20% overall and memory price hikes driving up costs. Apple's new requirements for supply chains such as UTG and hinges may push domestic processes toward maturity, but validation cycles are measured in quarters and will not affect the competitive landscape within six months.

**5. Repair prices and ecosystem adaptation will determine the course of future competition**

Users without AppleCare+ must pay 7,998 yuan to replace the inner screen, and 1,898 yuan for the battery—the most expensive in iPhone history—directly affecting upgrade decisions and second-hand resale value. Apple rarely makes such a high-profile show of support for iPhone Duo gaming adaptation, signaling that it is shifting the focus of competition toward a large-screen AI ecosystem rather than hardware form factor. 2026-10-19 22:40 The iPhone Duo that sold out in one minute puts Apple's production shortfall on full display | Old Uncle Quick Take

At 8 p.m. on October 16, Apple punctually opened pre-orders in China for its first foldable phone, the iPhone Duo. Yet just one minute later, the new device pushed Apple itself into an awkward position that is hard to explain.

From all models selling out on JD.com and Tmall within one minute, to the purchase pages on Apple's official website and the Apple Store temporarily failing to load due to a surge in instantaneous traffic, who could actually buy an iPhone Duo instantly became a question many Apple fans were eager to answer.

Moreover, the difficulty of buying an iPhone Duo can no longer be simply described as high popularity. About 12 minutes after pre-orders began, multiple Apple retail stores around Shanghai could no longer accept reservations for in-store pickup on the October 23 launch day; in less than half an hour, the estimated shipping time on Apple's China website was already scheduled for January 22-23, 2027. Even supply in the U.S. market was simultaneously tight; according to 9to5Mac, shipping dates for all versions were pushed to January 25, 2027.

Obviously, for the iPhone Duo, there are far more people in line than devices. Relevant media statistics put the number of reservations on JD.com alone at over 3 million, not counting reservations on the official website and Tmall, while industry estimates put first-batch all-channel supply at no more than 200,000 units.

With supply falling short of demand, the supply gap naturally soon turned into prices in the secondary market. Data from the Dewu app shows that the average pre-sale transaction price for multiple versions of the iPhone Duo exceeded 20,000 yuan, with the 1TB black version approaching 29,000 yuan, 7,143 yuan above the launch price.

Interestingly, despite the high premium, compared with September, before the device was released, when the 1TB version on Dewu was once quoted at 79,999 yuan with a premium of as much as 58,000 yuan, the current shrinkage of more than 50,000 yuan seems to indicate that consumers do not want it as much as imagined.

All these scenes together point to something unusual about this pre-order for Apple. Bloomberg reporter Mark Gurman said bluntly that Apple made a big mistake this time: insisting on launching despite knowing supply was severely constrained will disappoint many early users who have been eagerly waiting.

On one side is record demand, on the other is production capacity pushed to its limit, and in between are hundreds of thousands of buyers who have paid and must wait three months. This inevitably prompts questions about why Apple cannot make enough devices, why it insists on starting sales on time despite knowing of shortages, and what Samsung and Huawei will face once it enters the market.

What is holding Apple back is three process hurdles

Looking at it now, the warning bells for iPhone Duo pre-orders had already rung earlier.

On October 11, Gurman disclosed in a Bloomberg column that the iPhone Duo had encountered severe supply constraints, worse than Apple's internal expectations. Two months earlier, Apple had at one point believed it could not launch before late November; although it ultimately gathered enough inventory to support an October release, the cost was limited supply during the initial launch phase.

As for the 10-million-unit stocking target once discussed in the industry, it came from Apple's annual production and sales plan formulated at the end of 2025, and now it has clearly suffered a dramatic shrinkage. Counterpoint Research analyst Liz Lee said that in the first half of this year, Apple's foldable OLED panels encountered setbacks in production stability and delivery timing, the device plan was delayed, the hinge link underwent design adjustments, and the time ultimately required for final assembly to reach stability exceeded expectations.

Specifically, Apple faces multiple bottlenecks including panels, hinges, and final assembly.

First is the hinge. Multiple supply chain sources say that the iPhone Duo uses Apple's self-developed hinge mechanism, which internally contains more than 80 to over a hundred precision parts; the figures vary by source, but what is consistent is the tolerance requirement—some parts have machining tolerances controlled at the 0.01 mm level, equivalent to one-seventh the thickness of a human hair—and the device must pass more than 200,000 folding tests.

Because machining a single hinge part for one device takes several hours, and because Apple adjusted the design before mass production, upstream production lines had to repeatedly debug along with it, so the time left for ramping up was greatly compressed.

Second is the panel. It is reported that the iPhone Duo's inner screen is mainly supplied by Samsung Display, with some reports also mentioning LG Display's participation, using a solution of UTG ultra-thin flexible glass plus foldable OLED. The uniformity of foldable OLED in the evaporation process directly determines the depth of the crease; industry yield rates are generally below 70%. Considering that Samsung Display's foldable panels had previously been reported to have insufficient yield and delayed delivery, insufficient incoming materials directly compressed the downstream debugging window.

Finally, device assembly. People close to the Foxconn supply chain revealed that as of September 17, the assembly yield rate of the iPhone Duo was only slightly above 60%. By comparison, the yield rate of Apple's mature models is above 97%, meaning that for every 10 units produced, nearly 4 fail quality inspection.

Given that foldable screen lamination, battery installation, and mid-frame calibration are far more difficult than for slab phones, the iPhone Duo production line has to debug while producing, resulting in a daily output of only a few hundred units as of August.

A few other figures also make the iPhone Duo's capacity situation clear.

Ming-Chi Kuo expects that in the third quarter of this year, iPhone Duo assembly shipments will be only 500,000 to 1 million units, with the first batch of domestic supply at only a few hundred thousand units; according to analyst Jeff Pu's estimate, constrained by hinge capacity, he lowered his 2026 shipment forecast from 7 million to 6 million units; Counterpoint predicts iPhone Duo's full-year shipments will be at most 6 million units, and TrendForce's report on September 10 gave a figure of about 5 million units.

By comparison, the iPhone 18 Pro series is expected to ship 72 million units by the end of the year over the same period, and the Duo is less than one-twelfth of that.

Accordingly, the ramp-up pace determines this machine's final result this year. And the current shortage exposes the real situation of Apple's supply chain in terms of process accumulation when making a foldable screen for the first time.

With a 20.2-million-unit pie, how much can Apple take from Samsung and Huawei?

Setting aside the capacity problems it is currently facing, Apple is actually entering a market whose growth has already slowed.

TrendForce expects global foldable phone shipments in 2026 to be about 20.2 million units, only a slight increase of 0.5% over 2025. Excluding Apple's contribution, Android brands combined will be about 15.2 million units, a year-on-year decline of more than 20%, mainly due to sharp rises in component costs.

It should be noted that in this shrinking market pie, Samsung is expected to ship about 7.1 million units for 35.1%, and Huawei about 5 million units for 24.8%.

Looking at Counterpoint's forecast methodology in September this year, it expects cumulative global foldable phone shipments to exceed 100 million units by the end of 2026. That year, Samsung will remain first with a 38% share, Apple will rise to second with up to 6 million units and 25%, and Huawei will rank third with 22%.

The two sets of data differ in absolute values, but the conclusion is the same: Apple will take a quarter of the share in its first year, directly surpassing Huawei.

Interestingly, even if Apple really gets this share, it will not be relying on accumulated reputation. Considering that the sales window from the October debut to the end of the year is only more than two months, what supports the iPhone Duo's share is existing users' willingness to upgrade.

A Counterpoint research director believes that there are about 1.4 billion iPhone existing users. Even if only a small proportion are willing to try something new, short-term potential buyers would be close to 6 million, which exactly matches the firm's full-year capacity forecast of 6 million units.

But although demand is optimistic, it should also be noted that foldable screens still account for only about 2% of the global smartphone market, and their price is about three times that of traditional slab phones. Against this backdrop, the quarter that Apple takes is a quarter of a market that has not yet "grown up."

This means that if Apple wants to succeed through the iPhone Duo, it also bears the expectation of single-handedly raising the ceiling of the global foldable phone market.

How Huawei defends its 5-million-unit sales becomes a new test for the domestic supply chain

From the market landscape of foldable phones, after Apple enters, the most direct pressure will undoubtedly fall on Huawei.

Over the years, Huawei has maintained its lead in the Chinese market through a multi-form foldable screen layout. In 2026, its shipments are expected to be about 5 million units, almost the same as Apple's forecast.

However, the same numbers do not mean the same situation. Apple's 5 million or 6 million units are net additions, while Huawei must defend its 5 million units in an environment where the Android camp as a whole is declining by 20%, and with memory chip price increases driving up full-device costs, all Android manufacturers, including Huawei, are facing real pressure.

Of course, for the domestic supply chain, the iPhone Duo also brings new opportunities. TrendForce judges that Apple's requirements for displays, UTG, hinges, and overall device structure are expected to drive supply chain technology maturity and expanded mass-production scale.

Among these, UTG, or ultra-thin flexible glass, is a key material for foldable screen covers, and its yield rate and cost determine whether foldable screens can be sold at lower prices. As the iPhone Duo ships, the accumulated expertise of domestic manufacturers in this segment will be tested again. However, the validation cycle for such processes is often measured in quarters, so for at least six months, Apple's orders will not change the industry's competitive landscape.

If the iPhone Duo wants to take share from competitors, usage costs are also a hurdle it must overcome.

According to the repair prices already published on Apple's official website, for users without AppleCare+, replacing an iPhone Duo inner screen costs 7,998 yuan, close to the price of a top-spec Android slab flagship; outer screen damage costs 3,198 yuan, and the battery costs 1,898 yuan, the most expensive battery in iPhone history.

Based on past experience, screens are wear-prone components of foldable phones, so Apple's repair pricing will directly affect consumers' upgrade decisions and the devices' second-hand residual value, and in turn affect sales performance.

More importantly, looking to the future, the next stage of competition in the foldable phone market is increasingly moving away from hardware competition and focusing on the large-screen ecosystem.

TrendForce notes that after generative and multimodal AI enter phones, usage scenarios will extend from single-app operation to real-time translation, content generation, and cross-app collaboration, and the larger display space after unfolding can simultaneously present AI-generated content, source materials, and other apps. Apple has connected Apple Intelligence and Siri to the iPhone Duo, and whether the large screen can support these experiences will determine whether it can break away from the path of hardware differentiation.

On October 16, Cook visited miHoYo in Shanghai, where engineers demonstrated a game running on the iPhone Duo. Apple personally visiting developers to do adaptations shows that it itself understands that screen size only solves the form-factor problem, and only when the app ecosystem keeps up can it gain a firm foothold.

In my view, the signal value of this matter is greater than its PR value. Apple has rarely lent such high-profile support to third-party adaptation for a single product in the past, which means Apple wants to quickly push the foldable screen ecosystem toward maturity.

Given factors such as production capacity shortcomings, the competitive environment, and the large-screen ecosystem, compared with the current rush to buy the iPhone Duo in the market, the capital market's reaction has been more calm.

On October 16, Apple's stock price edged up 0.43% to $343.46 at the U.S. market close, though it was fortunately the only one among the week's seven major tech stocks to close higher. Analysts at Bloomberg Intelligence expect iPhone Duo sales to potentially exceed $28 billion in fiscal 2027, but this is premised on production capacity ultimately being able to ramp up.

As an ancient Chinese saying goes, one who stands on tiptoe cannot stand firm, and one who takes giant strides cannot go far. Correspondingly, Apple watched Samsung and Huawei spend six years turning foldables into an annual shipment category of 20 million units, yet pushed its product onto the stage in October before production capacity was ready, which inevitably raises concerns about its subsequent situation.

Incoming CEO Ternus's new answer, different from Cook's, will ultimately have to be proven on Apple's production lines in Zhengzhou and Shenzhen, China. Channel: 3C Digital.
