The iPhone Duo is far more versatile than the iPhone Air thanks to its
second, tablet-sized screen. But it's also heavier and much more expensive.

The iPhone Air is slim, stylish, lightweight, and a much cheaper option than the iPhone Duo, but it can't match Apple's foldable for photography or versatility. Pros Slim and light Relatively affordable High-quality screen Cons Only one rear camera Low battery capacity Less powerful The iPhone Duo and iPhone Air are both oddities in Apple s current smartphone lineup. Theres only one of each, and they meet fundamentally different user needs.

Sure, they're both extremely sleek and slim (assuming were talking about the iPhone Duo in its unfolded form), and they share some other similarities. But for the most part, these two iPhones couldn't be more distinct. In this article, then, weve compared the iPhone Duo and iPhone Duo in full, to help you decide which model is right for you.

The iPhone Air is a bit older, having launched back in September 2025, but with no successor yet available, you can still buy it.

The Duo comes in four configurations, with the cheapest being a 256GB option for $1,999 / 1,999 / AU$3,499. Next up, theres a 512GB version for $2,199 / 2,199 / AU$3,899, with a 1TB model costing $2,599 / 2,599 / AU$4,699, and a 2TB configuration coming in at $3,199 / 3,199 / AU$5,899.

The iPhone Air also starts in a 256GB configuration, costing $1,099 / 1,099 / AU$1,899, while the 512GB model is $1,299 / 1,299 / AU$2,299, and the 1TB version is $1,699 / 1,699 / AU$3,099. Theres no 2TB version of this phone.

So, the iPhone Duos starting price is some $900 / 900 / AU$1,600 higher than the iPhone Airs, and to be honest, you're unlikely to need to pay full price for Apple's super slim handset. It's regularly on sale at third-party retailers including Amazon , so the price gap between it and the iPhone Duo
is $900 / 900 / AU$1,600 at worst .

With the money youd be saving by buying the Air, you could also buy an iPhone 17 or an iPad Air , which speaks to how expensive Apple's first foldable
phone is. What to read next iPhone Duo vs Samsung Galaxy Z Fold 8: 7 key differences Apple iPhone Duo vs Samsung Galaxy Z Fold 8: a big battle of

AU$3,099 iPhone Duo vs iPhone Air: design Image 1 of 2 (Image credit: Future) (Image credit: Future) Image 1 of 2 View Original Image 2 of 2 View Original Both of these phones are, first and foremost, examples of beautiful design.

With the iPhone Duo, Apple managed to make a remarkably slim phone thats just 117.8 x 164.6 x 5.2mm when unfolded. That makes it even thinner than the
156.2 x 74.7 x 5.6mm iPhone Air a phone that has a slim design as one of its main selling points.

Of course, when folded shut as it will be in your pocket the iPhone Duo is rather chunkier at 117.8 x 84.1 x 11.3mm. At 254g, the Duo also weighs a lot more than the Air, which clocks in at a remarkably light 165g.

Before we move on, it's worth reiterating that these measurements make the
Air one of the most comfortable phones to use and hold over long periods. Its slimness might seem like a gimmick, but there's a lot to be said for using a phone that feels almost weightless in your hand and pocket.

The Duo is equally well-crafted and impressively thin when unfolded, but in day-to-day use, it feels significantly heavier and chunkier than the Air. But then, with two screens, that was inevitable. Image 1 of 2 The iPhone Duo (folded) and iPhone Air (Image credit: Future) The iPhone Duo (unfolded) and iPhone Air (Image credit: Future) Image 1 of 2 View Original Image 2 of 2
View Original As far as durability goes, both phones have a Ceramic Shield 2 glass front, a Ceramic Shield glass back, and a titanium frame, and both also have an IP68 rating for dust and water resistance.

Of course, foldables are inherently more fragile than single-screen phones like the iPhone Air, but you needn't worry about the Duo breaking after a few folds Apple has confirmed to TechRadar that the phone's viral
screen-cracking issue only affected a "small number of units" at launch.

The iPhone Duo and iPhone Air also look somewhat similar from the back, with both having a horizontal camera block though this block houses two lenses on the iPhone Duo, and just one on the iPhone Air.

On the front, the Air has larger cutouts in its screen, allowing for Face ID something the iPhone Duo lacks. And the two phones come in different colors, with the iPhone Duo being available in Night Sky and Star White shades, while the iPhone Air is sold in Space Black, Cloud White, Light Gold, and Sky Blue shades.

So, there are as many differences as similarities here, but the designs of both phones shine, with our iPhone Duo review praising Apple's foldable as beautifully designed and engineered, while our iPhone Air review called it
the freshest look that Apple has delivered in years. These are two great-looking products. iPhone Duo vs iPhone Air: display Image 1 of 2 The iPhone Duo (Image credit: Lance Ulanoff / Future) The iPhone Air (Image credit: Jacob Krol/Future) Image 1 of 2 View Original Image 2 of 2 View Original You may not have noticed, but the iPhone Duo has two screens.

Its main foldable display is a 7.6-inch 1878 x 2670 LTPO Super Retina XDR
OLED panel with 430 pixels per inch, a 120Hz refresh rate, a peak brightness of 3,000 nits, and an anti-glare nano-texture finish.

Its smaller cover screen is a 5.4-inch 1398 x 2034 LTPO Super Retina XDR OLED panel with 60 pixels per inch, a 120Hz refresh rate, and a peak brightness of 3,000 nits.

The iPhone Air, of course, just has one screen a 6.5-inch 1260 x 2736 Super Retina XDR OLED panel with 460 pixels per inch, a 120Hz refresh rate, and a peak brightness of 3,000 nits. (Image credit: Future) The specs and quality
of both phones' front screens are similar, with our iPhone Duo review saying it has a bright, sharp, fluid display, and our iPhone Air review calling its screen punchy, sharp, and smooth. So youre mostly just choosing whether you want one screen or two, and what size(s) you want.

That said, having two displays undeniably makes the iPhone Duo more
versatile, as its suited to both large-screen and small-screen tasks it also supports the Apple Pencil, which the iPhone Air doesnt.

The nano-texture finish on the Duo's inner screen is a sight to behold, too. It does an excellent job of preventing glare, and an even better job of
hiding the phone's crease when viewed straight-on. This crease is, of course, still visible when viewed at an angle, but that doesn't really matter if it's not visible when the Duo is in use. iPhone Duo vs iPhone Air: cameras Image 1 of 2 The iPhone Duo (Image credit: Lance Ulanoff / Future) The iPhone Air (Image credit: Jacob Krol/Future) Image 1 of 2 View Original Image 2 of 2
View Original iPhones tend to excel at photography, but arguably neither of these devices ranks among Apples best. Still, of the two, the iPhone Duo has the edge by virtue of having more cameras.

On the back, it has a 48MP f/1.6 wide camera and a 48MP f/2.2 ultra-wide one (with a 120-degree field of view). Then, on the cover screen, it has a 12MP f/2.2 punch-hole camera, and on the foldable screen, it has a 4MP f/1.8 under-display one.

The iPhone Air, on the other hand, has a solitary 48 MP f/1.6 wide camera on the back, and an 18MP f/1.9 camera on the front.

So the main difference here is that theres no ultra-wide lens on the iPhone Air, making the Duo more versatile for photography. But the Air does have a superior selfie camera, even if the Duo has two front-facing snappers (the
4MP inner-display camera is really not very good).

All that said, both phones are still capable ot taking excellent shots. In
our iPhone Duo review, we said it has two strong 48MP lenses and an above-average Center Stage selfie camera, while in our iPhone Air review, we said its camera delivers sharp, natural photos and impressive portraits, but lacks the versatility found on other models. iPhone Duo camera samples Image

The iPhone Air is a step down from that, with an A19 Pro chipset, 12GB of
RAM, and no vapor chamber.

As such, the Air isnt quite as high-performing, though unless youre really pushing it with high-end games or other demanding tasks, youre unlikely to notice much of a difference, and both phones are speedy.

This was reflected in our use of the two devices, with our iPhone Duo review finding that it offered smooth performance across the board, while our iPhone Air review said it feels fast and smooth in daily use, though it can warm up under sustained heavy gaming. The Air occasionally heats up during FaceTime calls, too. Image 1 of 2 The iPhone Duo has a side-mounted app dock (Image credit: Lance Ulanoff / Future) Some apps still aren't optimized for the Duo (Image credit: Lance Ulanoff / Future) Image 1 of 2 View Original Image 2 of
2 View Original As for software, the iPhone Duo launched with iOS 27.1 out of the box, while the iPhone Air being older shipped with iOS 26. But both phones can be updated to iOS 27.2 at the time of writing, so theres not much to choose between them here, though the Duo does feature some unique touches like a side-positioned dock.

However, its worth noting that it might take a while for all apps to be optimized for the iPhone Duos form factor. First-party apps like Messages and Mail look great on either Duo screen, but third-party apps like YouTube and Instagram still need work.

This early-stage clunkiness may well be resolved by the time you're reading this, but don't be surprised if you encounter some software-related oddities on the iPhone Duo. iPhone Duo vs iPhone Air: battery Image 1 of 2 The iPhone Duo (Image credit: Lance Ulanoff / Future) The iPhone Air (Image credit:
Jacob Krol/Future) Image 1 of 2 View Original Image 2 of 2 View Original The iPhone Duo has a 4,883mAh battery, while the iPhone Air has a far lower-capacity 3,149mAh cell. This, unsurprisingly, also means the iPhone Duo lasts longer, with Apple claiming youll get 44 hours of video playback from
it when using the cover screen or 31 hours with the foldable display, while the iPhone Air is quoted at 27 hours.

This largely tallies with our test results. In the case of the iPhone Duo,
our reviewer found that all-day battery life is virtually assured, while for the iPhone Air we found that it should last a workday, but heavy users will need to recharge.

And when you do recharge, the iPhone Duo can reach 50% in roughly 20 minutes with a 60W or higher charger, or if youre using wireless charging, it can get to 50% in around 30 minutes with a 35W or higher MagSafe charger.

The iPhone Air takes about 30 minutes to reach a 50% charge whether using wired or wireless charging, so its slightly slower here. iPhone Duo vs iPhone Air: verdict (Image credit: Future) The iPhone Duo is far more expensive than the iPhone Air, and that price difference is probably the main thing you need to consider when choosing between them especially as you could buy the
iPhone Air and an iPad for less money than the iPhone Duo.

Of course, there are advantages to having two devices in one, and the iPhone Duo is a better phone than the Air in various ways too it boasts slightly better performance, longer battery life, an extra camera, and, of course,
that all-important second screen.

Both phones have sumptuous designs, though, and the iPhone Air can hold its own for screen quality it also features Face ID, which the iPhone Duo lacks.

So, if you want a more affordable, beautiful-to-use iPhone that works like every other iPhone you've ever owned, go for the Air. If you're willing to
try something new and happy to pay for the privilege of doing so the Duo is the obvious choice.
