Analysis
Apple unveiled the iPhone Duo, its first foldable smartphone, at a September 9 event the company called "Surprise and Shine," alongside the iPhone 18 Pro and iPhone 18 Pro Max, Variety reported. The device starts at $1,999 for the base 256GB configuration, pairs a 5.4-inch outer display with what Apple calls its largest-ever iPhone screen -- a 7.6-inch internal display Apple says offers 50% more screen area than the iPhone 18 Pro Max. Pre-orders open October 16, with the phone shipping October 23.
The Duo is a passport-style foldable -- opening top-to-bottom rather than book-style -- built around Apple's new A20 Pro chip, Tom's Guide reported. TechCabal and other outlets noted the design closely mirrors Samsung's now-familiar Galaxy Z Fold form factor rather than a flip-style design, and that iOS 27 has been rebuilt around the fold: Split View multitasking, hands-free FaceTime that repositions itself depending on how the phone is held, StandBy mode that works without a charger, and layouts that shift as the device opens and closes.
Five years behind, and pricing above the category
Apple is the last of the major smartphone makers to ship a foldable. Samsung's original Galaxy Fold launched in 2019 -- after a delayed, embarrassing relaunch following early review-unit hinge failures -- and the company has iterated through eight generations of Galaxy Z Fold and Z Flip devices since. Huawei, Honor and Oppo have all shipped multiple foldable generations in China, and Google entered the category with the Pixel Fold in 2023. Apple's decision to wait -- reportedly slowed by durability and crease-visibility concerns with its own hinge and display designs -- means the iPhone Duo arrives into a category rivals have spent five years refining, not one Apple is defining for the first time.
Apple's pricing bet is the more interesting story than the wait itself. At $1,999, iPhone Duo starts meaningfully above Samsung's current-generation Galaxy Z Fold, which has typically launched in the same general price band but with more aggressive trade-in and carrier subsidies driving effective prices down. Apple is betting its brand, software polish and iOS 27's fold-native features justify a premium that could otherwise push budget-conscious upgraders toward a standard iPhone 18 Pro Max instead -- a device with a larger, more mature app ecosystem for a lower sticker price and no fold-related durability tradeoffs.
The competitive and durability questions
Android foldables have taken half a decade to solve problems Apple's Duo will now face fresh: hinge durability under repeated folding, crease visibility on the inner display, third-party app layouts that don't gracefully handle a mid-screen fold, and battery life split across two displays. Samsung's early Galaxy Fold generations struggled visibly with all four; later generations improved materially but never fully eliminated crease visibility, an issue every foldable maker, almost certainly including Apple's first generation, will face regardless of engineering investment.
Whether the Duo sells at genuine scale, rather than as a halo device for Apple's wealthiest and most loyal customers, will show up first in how competitors respond: Pulse has tracked Samsung's own chip and display supply chain closely this year, and Samsung, Honor and Google have all signaled their own next-generation foldables are coming within the following two quarters. A strong Duo launch would validate premium foldable pricing across the category, while a soft one would hand Samsung fresh ammunition in a fight it has led uncontested for five years.
