Apple iPhone Duo

After years of rumors about it, Apple has finally released its first foldable device, the iPhone Duo.

The Duo brings a whole new form factor to the iPhone lineup. Its book-style design features a 5.4-inch outer display that unfolds into a massive 7.6-inch screen—the largest ever on an iPhone. Think smartphone convenience with a tablet-sized viewing experience.

But the Duo has more going for it than a flashy folding screen. It packs the same powerful A20 Pro chip as the iPhone 18 Pro, delivering up to 40% faster graphics than the previous generation. And at just 5.2mm thick when unfolded, it’s also Apple's thinnest iPhone ever.

Of course, Apple's biggest iPhone innovation in years comes with a price tag to match. Below, we'll break down what the iPhone Duo costs, what makes it different, and where to find the best deals on Apple's first foldable phone.

iPhone Duo Release Date

The iPhone Duo was unveiled on September 9, 2026, at Apple’s annual event. Preorders opened on Friday, October 16, 2026, and hit shelves on Friday, October 23, 2026.

iPhone Duo Price

Apple's first foldable iPhone comes with a price tag that's every bit as big as its screen. The iPhone Duo starts at $1,999 for the 256GB model, while the top-of-the-line 2TB version will set you back a whopping $3,199. This makes the Duo Apple's most expensive iPhone ever, and a serious investment even by flagship smartphone standards.

Here's how pricing breaks down across the four storage options:

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

iPhone Duo Features and Specs

The iPhone Duo's folding display may steal the spotlight, but there's plenty more to Apple's newest device.

Both screens feature Super Retina XDR OLED technology, a smooth 120Hz ProMotion refresh rate, and up to 3,000 nits of peak outdoor brightness. All that screen comes with some bulk, though. At 11.3mm thick when folded and weighing 254 grams, the Duo is Apple's heaviest iPhone yet.

The Duo also makes a few compromises. Its dual 48MP cameras lack the dedicated telephoto lens found on the iPhone 18 Pro, and Touch ID replaces Face ID, with a fingerprint sensor built into the side button.

Rounding things out are up to 24 hours of mixed-use battery life and two color options: Star White and Night Sky.
