Foldable Showdown: How Global Rivals Are Outpacing Apple’s iPhone Duo on Hardware

The foldable market accelerates as competitors launch thinner, lighter, and better-equipped devices ahead of Apple’s entry.

Although Apple has yet to release its first foldable — the iPhone Duo, slated for an October 23 launch with pre-orders opening a week prior — the industry has been preparing for this moment for years. Manufacturers have long anticipated how Apple might reshape the book-style foldable segment, and several have already brought compelling alternatives to market.

The competitive landscape is formidable. Xiaomi, Oppo, Motorola, and Samsung all offer passport-style foldables that mirror the Duo’s form factor. The question remains whether hardware advantages alone can withstand the gravitational pull of Apple’s ecosystem.

Xiaomi and Samsung Redefine the Wide Format

The Xiaomi 18 Fold debuted days before the Duo’s unveiling, matching its core specifications: a 7.6-inch inner display and 5.4-inch cover screen sharing the same aspect ratio. Xiaomi claims notable hardware leads, however. At 219 grams, the 18 Fold is 35 grams lighter than the 254-gram iPhone Duo. It also fields a triple-camera array, providing an optical zoom range the Duo lacks. Pricing starts at 10,999 yuan (approximately $1,640), though availability remains restricted to China for now.

In the U.S., the Galaxy Z Fold8 stands as the Duo’s primary rival. Samsung abandoned the near-square footprint of prior generations for a wider passport layout with 7.6-inch and 5.5-inch panels, opting for sharp corners over curved edges. Our review scored it 8.9/10, praising its media consumption experience over the pricier, square-shaped Z Fold8 Ultra. Like the Duo, it features a dual-camera system. However, at $1,900 — just $100 below the Duo’s starting price — Samsung’s value proposition hinges on software maturity rather than cost.

Oppo and Motorola Prioritize Battery, Charging, and Thinness

Oppo’s Find N6 retains the traditional foldable proportions seen on the Z Fold8 Ultra, with a 6.62-inch cover screen and 8.12-inch interior panel. Its differentiator is slimness: at 8.93mm folded, it approaches the 8.75mm thickness of a standard iPhone 18 Pro, besting the Duo’s 11.3mm. A 6,000mAh battery — 1,600mAh larger than the Z Fold7’s — pairs with 80W wired charging. The spec sheet adds IP59 water resistance and a 200-megapixel main sensor. While a global variant exists, official U.S. sales are absent; pricing starts at 9,999 yuan (roughly $1,490).

The Motorola Razr Fold offers a stateside alternative with similar dimensions: a 6.6-inch external display unfolding to an 8.1-inch internal panel capable of 6,000-nit peak brightness, doubling the Duo’s 3,000-nit maximum. It matches the Find N6’s 6,000mAh battery and 80W charging while adding a triple-camera system with optical zoom and optional stylus support (a $100 accessory). The Razr Fold retails from $1,900.

Despite the hardware onslaught, Apple enters the arena with software as its force multiplier. iOS 27 introduces extensive foldable optimizations — fluid cross-display animations, versatile multitasking modes, and interface continuity — areas where Android’s fragmentation still shows seams. The Duo’s success may ultimately hinge not on spec sheets, but on how seamlessly Apple translates its ecosystem advantage to a new form factor.
