Apple Says It Can't Predict When iPhone Duo Will Return to Stock

Apple told investors Monday that it does not know when it will restock the foldable iPhone Duo, which sold out roughly a week after its late-October launch, according to the BBC. The company described the shortage as a byproduct of component "constraints" rather than a one-time launch glitch.

What did Apple say about the Duo shortage?

Apple reported that it is "really hard to predict when supply and demand will be in balance" for the Duo, the company's first major iPhone redesign in roughly two decades, the BBC reported. The device launched at nearly $2,000, Apple's highest price point for a smartphone, and sold out before Thanksgiving-season demand even peaked. Chief operating officer Sabih Khan said the company was working to get the phone "into the hands of our customers as quickly as possible," but offered no restock date, per the BBC.

How did the rest of Apple's iPhone and Mac business perform?

The shortage sits alongside otherwise strong quarterly results. Apple's fiscal quarter ended Sept. 26, before the Duo went on sale, so none of its figures include foldable sales, the BBC reported.

By the numbers

• iPhone revenue: $57bn, up 17% year over year
• Mac revenue: $10.7bn, up 27%, a record
• Total company revenue: $114bn, up from $102bn
• Pre-tax profit: $36.1bn, up from $32.8bn
• iPad revenue: down 10%
• Wearables (headphones, watch): down 7%

Apple said it sold more iPhones globally over the past year than in any prior year, according to the BBC.

Why are memory chip prices rising for Apple?

Chief executive John Ternus, who took over from Tim Cook in September and launched the Duo, said Apple is seeing an "unprecedented" increase in memory costs, including chips, the BBC reported. Much of that memory runs through data centers, where demand has climbed as AI platforms from companies including OpenAI and Anthropic expand, according to the report. Cook had flagged a similar jump in data-center-driven costs earlier this year, the BBC noted.

Separately, Khan said most Apple devices remain constrained by limited supply of advanced-node microprocessors, chips largely manufactured through Taiwan-based TSMC that let devices run faster. Khan said he expects that constraint to continue into next year, hitting iPads and Macs in particular, the BBC reported. Apple has repeatedly attributed the squeeze to what it calls "unexpected demand," according to the outlet.

What is known about the Duo's screen problems?

Apple said last week it would replace Duo handsets affected by a defect causing a "small number" of units to crack along the inside fold, the BBC reported. Some buyers had reported the issue publicly. During Monday's earnings call, Apple executives did not raise the screen problem, and Ternus instead said he was "thrilled" by the early reception to the foldable phone, per the BBC. The BBC did not report a defect rate or total unit count tied to the screen issue, and no third-party testing data accompanied Apple's statement.

What should shoppers watch for before Christmas?

• Whether Apple issues a restock date or timeline for the Duo before the holiday shopping window closes
• Whether memory and advanced-node chip shortages Khan described extend restock delays to iPads and Macs, as the company has signaled
• Whether additional reports of the fold-crack defect surface, and how Apple's replacement process handles volume if they do
• Whether Ternus or Khan offer updated supply guidance on Apple's next earnings call

The company's own numbers show the tension plainly: iPhone and Mac revenue both grew at double-digit rates even as Apple says it cannot source enough high-end chips and memory to meet demand for its newest device. Apple has not said whether the Duo's shortage reflects underestimated demand, component constraints, or both — and based on its public statements, the company says it does not yet know either.
