Apple’s first foldable device, the iPhone Duo, arrives in stores on October 23, 2026, following the start of pre-orders on October 16.
iPhone Duo Features Titanium Hinge and Large Display
The iPhone Duo features a precision-engineered titanium hinge and a 7.6-inch inner display, complemented by a 5.4-inch outer cover screen. Apple describes the device as its largest iPhone display ever in a foldable form factor. The unit is splash-, water-, and dust-resistant with an IP68 rating. Weighing 254 grams, it is heavier than the 249-gram iPhone 18 Pro Max. Reviewers have noted a matte “nano-texture” coating on the inner display, which is designed to reduce glare and the appearance of the screen crease.

Powered by the A20 Pro chip and supported by a thermal management system including a vapor chamber, Apple claims the Duo delivers up to 35% higher sustained performance compared to the iPhone 17 Pro. In battery testing conducted by Tom’s Guide, the device recorded 13 hours and 20 minutes in a web-browsing test using the larger display, 5G connection, and brightness set to 150 nits. This compared to 10 hours and 6 minutes for the Samsung Galaxy Z Fold 8 and 17 hours and 31 minutes for the iPhone 18 Pro Max in the same simultaneous test conditions.
Split View Struggles in Portrait Orientation
Early reviews from outlets including The Verge and Tom’s Guide identified that Split View multitasking functions well in landscape orientation but struggles when the device is rotated into portrait. Developers can use Xcode 27.1 to support adaptive screen sizes, but unoptimized apps remain a point of friction.

The menus are difficult to learn. Reviewers noted that interface controls are positioned for specific reachability, and Apple has reportedly been preparing a software update to fix how users move through the system. The device also utilizes Touch ID in the power button rather than Face ID, a choice that some users found less fluid for authentication tasks like Apple Pay.
Apple Offers Leasing and Trade-In Credits
The iPhone Duo is a new foldable device from Apple that features a large inner display and a starting price point that is high compared to other smartphones. For customers seeking more accessible payment options, Apple offers leasing through Klarna via Apple Upgrade, with prices starting as low as $57.99 per month for a 24-month lease, excluding taxes and trade-in credits. Apple Card users in the U.S. can also utilize Apple Card Monthly Installments at 0 percent APR.
Through Apple Trade In, customers can receive instant credit ranging from $175 to $885 when trading in an eligible iPhone 13 or higher. Additional incentives are available through carriers like Verizon, which offers specific plans including the Simplicity Plan with Simplicity Pro. Apple has confirmed that U.S. retail stores will have a limited number of units available for walk-in customers on launch day, though stores in other markets like Japan, France, and mainland China will be restricted to in-store pickup for online orders.
Apple Targets 11 to 17 Million Units
The iPhone Duo launches into a crowded market. Industry reports suggest Apple’s supply chain targets for the device range between 11 and 17 million units over the next year, a significant figure given that the entire foldable market to date is estimated at a much smaller scale. Historical data on supply partners, such as Skyworks Solutions, provides context for how component suppliers have historically outpaced Apple’s own growth following major product launches, though Apple has not confirmed specific suppliers for the Duo’s hinge or A20 chip.

As the October 23 launch approaches, Apple has begun preparing its flagship Fifth Avenue store in New York with large, concealed installations, continuing a tradition of special displays for new product releases. While early reviews provide a concrete picture of the device’s current capabilities, long-term display and hinge durability remain areas requiring extended observation by users and industry analysts alike.
