Apple on Wednesday redefined its flagship smartphone with the launch of the Duo, a folding $1,999 iPhone, betting its design and promises of data privacy will let it leap ahead of rivals who have been ​selling folding phones for years.

The Duo could shake up a category long dominated by Samsung and Chinese companies like Huawei, whose devices have struggled to move beyond a niche audience. Analysts have long said Apple’s entry could be the ‌catalyst foldables need, helping bring the form factor into the mainstream much as the company did with smartwatches and wireless earbuds.

Key Features 

Displays: It features a 7.6-inch inner display when unfolded and a 5.4-inch outer display when closed, which is similar in size to a passport. 

Design: Crafted from grade 5 titanium, Apple calls it their thinnest iPhone yet. 

Performance: It runs on the new A20 Pro chip and includes Apple’s C2 modem. 

Security: Touch ID returns on the device to replace Face ID, allowing easy unlocking whether the phone is opened or closed.

Availability: Pre-orders start on Friday, October 16, with official store availability beginning Friday, October 23, 2026.
