Apple introduced its first foldable iPhone, the iPhone Duo, priced from £1,999 in the UK and $1,999 in the US. The device marks the first significant iPhone design change in nearly two decades and represents the initial major product decision by new chief executive John Ternus, who succeeded Tim Cook earlier in the month. Development took eight years. The launch places Apple in a market already led by Samsung and Huawei, where foldables currently represent 2% of global smartphone sales.
What is the iPhone Duo and how does it differ from existing foldables?
The iPhone Duo unfolds to the size of a small iPad and folds into a wider iPhone form factor. Apple described it as passport-sized and comfortable for one-handed use. CEO John Ternus stated that competing foldables feel like two phones awkwardly joined, while the Duo redefines the foldable experience. The device required eight years of development, with Ternus directly involved during his prior roles in Apple hardware. When unfolded it resembles a small tablet; when folded it takes the shape of a wider conventional handset. Ternus emphasised that the form factor feels familiar to hold and that the overall experience remains remarkably familiar despite being entirely new. The company positioned the product against rivals by highlighting that other foldables simply feel like two phones stuck together. Ternus told an audience at Apple's California headquarters that the model redefines the experience of using a foldable phone after others created versions that just feel like two phones awkwardly stuck together. It has taken eight years to develop and marks the first major iPhone design change in almost 20 years.
How does pricing compare with previous iPhones and rival foldables?
The Duo starts at £1,999 in the UK and $1,999 in the US, with configurations reaching $3,200. This exceeds the previous highest iPhone starting price of $900. Apple simultaneously announced the iPhone 18 Pro at $1,199 and the iPhone 18 Pro Max at $1,299. Analysts note the premium positioning risks limiting volume, similar to the Vision Pro headset priced at $3,699. The highest previous starting price for a new iPhone model had been $900. The foldable therefore sits well above the standard range and enters a segment already occupied by established competitors from Samsung and Huawei. In the US prices start at $1,999 but can go up to $3,200. Previously the highest starting price of the newest iPhone was $900. The product is facing established competitors in a market where the real fight is China.
Who is John Ternus and why was the timing of his promotion significant?
John Ternus assumed the role of chief executive this month after years as a senior hardware executive. Analysts from FDM CCS Insight suggested the appointment was deliberately aligned with the foldable launch, described as one of the largest iPhone releases in years. The presentation placed Ternus in the spotlight, with some observers noting the event felt as though he were presented as a product himself. Nothing happens by accident at Apple, according to one analyst, and the timing of the promotion was viewed as linked to the significance of the new device. Ternus had spent many years inside the hardware division before taking the top role. Ben Wood, chief analyst at FDM CCS Insight, said it was likely Ternus's promotion was timed specifically to coincide with what will be arguably one of the biggest iPhone launches for many years. Carolina Milanesi noted the spotlight on Ternus made it feel almost like he was a product himself.
What market share and growth forecasts exist for foldable phones?
Foldable smartphones currently account for 2% of global sales. Huawei holds nearly 80% of the Chinese foldable segment. Projections from FDM CCM Insight indicate the category may reach 4% of the total smartphone market within the next decade, even with Apple’s entry expected to increase visibility. The iPhone line itself continues to generate more than half of Apple’s annual revenue. The real fight is in China, where one competitor already dominates the segment. Even with added interest from Apple, forecasts remain modest over the coming ten years. Francisco Jeronimo, vice president for data and analytics at IDC EMEA, said the real fight is China where Huawei owns nearly 80% of foldables. The iPhone has been Apple’s top-selling product and accounts for more than half of the company’s sales each year.
How will Siri AI integrate with the new devices?
Apple introduced Siri AI capabilities that can access messages, emails and other phone data to answer queries and perform actions. The features begin with the iPhone 18 series and extend to the Apple Watch for conversation transcription. Ternus emphasised that processing occurs on-device where possible and that third-party cloud functions maintain privacy standards, with Apple itself unable to access user data. The assistant is described as an intelligent personal hub that draws on the most private details of daily life yet keeps everything private. When third-party processing is required the data stays in a remote server that Apple cannot access. Others see data as something to collect and store, Ternus said, but here not even Apple can access what is yours. Some Siri AI features will also be available on the new Apple Watch including the ability to take notes of conversations and transcribe them.
Frequently asked questions
Will the iPhone Duo replace the standard iPhone lineup?
Apple presented the Duo as an addition to the portfolio rather than a replacement. The company continues to release conventional models such as the iPhone 18 Pro series alongside the new foldable.
How does the software experience differ from a traditional iPhone?
Analysts highlighted a learning curve when moving from a standard smartphone to a foldable. The Duo runs iOS with adaptations for the folding screen, yet users must adjust to new interaction patterns for apps and multitasking. A lot of people are intrigued by foldables but the software adjustment is real. Carolina Milanesi noted that the software and the learning curve from moving from a traditional phone to a foldable is real.
Is the price expected to limit adoption?
Analysts at Forrester warned the Duo could function mainly as a premium ornament with limited volume growth, citing the Vision Pro precedent. Others noted the Apple Watch achieved steady annual sales despite lower popularity than the iPhone. The foldable risks becoming a premium-priced ornament in the portfolio, imparting badge value but not meaningful growth. Dipanjan Chatterjee said it could go the way of the Vision Pro or become the next Apple Watch bought by millions each year.
When will the iPhone Duo become available?
Apple did not announce an exact shipping date in the initial presentation. Pre-orders and availability details are expected in the coming months following the September event.
Does Apple plan further foldable models?
The company has not confirmed additional foldable variants. The Duo represents the first entry, and future iterations will depend on sales performance and component supply.
Key takeaways
- Apple’s first foldable iPhone Duo starts at £1,999 / $1,999 after eight years of development.
- New CEO John Ternus led the project and presented it as his first major product decision.
- Foldables currently hold 2% global market share; forecasts see growth to 4% within ten years.
- Siri AI features debut on the iPhone 18 series with on-device privacy controls.
- Competitors Samsung and Huawei already occupy the segment, with Huawei dominant in China.
Outlook for Apple’s foldable strategy
The iPhone Duo tests whether Apple can convert its brand strength into meaningful share in a still-niche category. Success will hinge on balancing the high price point with software familiarity and actual consumer demand beyond early adopters. The coming quarters will show whether the device follows the trajectory of the Apple Watch or remains a limited-premium offering. Altering the iPhone design may address criticism that Apple has not delivered a major product hit or truly exciting innovation since 2007, yet the outcome remains uncertain. The iPhone has been Apple’s top-selling product and accounts for more than half of the company’s sales each year, with recent versions becoming its most successful product launch.
