For years, Samsung, Google and others sold folding phones while Apple waited. On 9 September, at an event it called "Surprise and shine", Apple finally showed its answer. "iPhone Duo" has since become one of the fastest-rising phone searches on Google worldwide.

The Design

The iPhone Duo opens like a book. Closed, it is a compact phone with a 5.4-inch outer display. Open, it becomes a 7.6-inch screen — the largest display Apple has put on an iPhone.

The inner screen has 50 percent more screen area than the iPhone 18 Pro Max.
The outer screen offers more than 90 percent of the screen area of an iPhone 18 Pro.
A titanium hinge made of more than 100 components allows an IP68 water-resistance rating — a first for a book-style foldable.

Inside

Chip. The Duo uses the same A20 Pro chip as the iPhone 18 Pro, built on a 2-nanometre process.

Battery. There is one battery cell in each half of the phone, totalling 4,883 mAh. With a 60-watt or stronger USB-C adapter, Apple says it can charge to 50 percent in about 20 minutes.

Price

256GB: $1,999
512GB: $2,199
1TB: $2,599
2TB: $3,199

That makes the base Duo $100 more than Samsung's Galaxy Z Fold 8 — compared in detail in our Fold 8 vs iPhone Duo guide.

Release Dates

Pre-orders: 16 October 2026
On sale: 23 October in more than 70 countries and regions
Second wave: 28 more countries on 30 October

Should You Buy One?

It suits people who want a tablet-sized screen for reading, video, spreadsheets or split-screen work without carrying a second device — and who are already comfortable in Apple's ecosystem.

It is less suited to anyone who wants the best value. At $1,999 it costs far more than an iPhone 18 Pro, and first-generation products have historically improved quickly in their second year.

Worth waiting for: independent reviews of hinge durability and battery life in daily use. Apple's claims are specific, but real-world testing will show how the Duo holds up over months, not days.

If a foldable is more than you need, the rest of Apple's September line-up is covered in our iPhone 18 Pro guide and our AirPods 5 guide.
