It’s official. Apple’s first foldable phone, the iPhone Duo, will be taking up a surprisingly small space in early adopters’ pockets next month.
It’s undeniably expensive, however. The base 256GB model will set you back $1,999 which critics have noted is more than it would cost to buy the iPhone 18 Pro and the latest iPad mini 7.
So is that worth doing, or does the unique form factor of the iPhone Duo justify the extra cost? Here’s what you should consider before making your choice.
Why you should choose iPhone Duo
Unmatched portability
The main thing the iPhone Duo has going for it is its portability.
When folded, it measures 117.8mm x 84.1mm x 11.3mm. Though that’s not too far removed from the iPhone 18 Pro’s 71.9mm x 150mm x 8.75mm, add in a 134.8mm x 195.4mm x 6.3mm iPad mini 7, and pockets alone just wouldn’t cut it.
And while the iPhone Duo weighs a not-insubstantial 254g, that’s still lighter than the combined weight of the phone and tablet, which together tip the scales at 504g.
When Tom's Guide sat down to talk with CEO John Ternus and Greg Joswiak following the Apple keynote, Joz specifically highlighted the joy of being able to fold up an iPad and take it around with you as part of the device's appeal.
Unique features
As well as the cool factor of a folding phone, the iPhone Duo has a couple of features that are unique to the iPhone family. The internal FaceTime camera is an under-screen model, only visible when required. And that internal screen has a matte finish for less glare and fewer reflections.
In addition, the iPhone Duo's apps can morph based on the folding state of the device. For example, if you're watching Netflix and fold the device like a laptop, you'll see the video up top and controls down below.
Also, bear in mind that while the iPhone Duo uses the same A20 Pro chipset as the iPhone 18 Pro and iPhone 18 Pro Max, the iPad mini 7 is a bit longer in the tooth, still using the same A17 Pro silicone as the iPhone 15 Pro. The iPad mini 8 will no doubt close the gap, but its release date (and likely price increase) is still to be determined.
Better multitasking
One of the main reasons people use a tablet is for the enhanced multitasking abilities that a larger screen offers.
While both the iPhone Duo and iPad mini allow multiple apps for genuine multitasking, the former has the advantage here. Why? Because all your files, apps and notes are in one place. With an iPad mini, you’d need to make sure your files were synced between devices — something made that bit harder if you opt for the Wi-Fi-only model.
Only one device to keep charged
Keeping electronics charged is one of the more tedious things about modern living. As a two-in-one device, you only need to monitor the battery of one handheld, rather than two.
Why you should choose an iPhone 18 Pro and an iPad mini
Significant savings
The most obvious advantage of opting for a phone and a tablet over the iPhone Duo is the price difference. An iPhone Duo starts at $1,999, whereas buying both an entry-level iPad mini 7 and a base iPhone 18 Pro together comes to $1,698 — a $301 saving. Even if you opt for an iPhone 18 Pro Max with the iPad mini, you'll still pay a combined $1,798 that comes in cheaper than the Duo. Given the iPad mini 7 is coming up to its second birthday, you’d be able to save a packet by shopping around, too.
These savings can be even greater if you opt for a different combo, too. The iPhone 17 starts at $899 on the Apple site, immediately slashing a further $300 from the price, and again, if you shop around, you’ll be able to get it cheaper.
The battery power of two devices
Though I already covered the hassle of having to top up two batteries, the flip side to this is the added longevity.
The iPhone Duo is expected to have a battery that will last for 44 hours of video on the outer screen, or 31 on the internal one. The iPhone 18 Pro is quoted as going for 34 hours of video (our own battery test knocked it out after 16 hours and 17 minutes of real-world endurance), and the iPad mini lasted just over ten hours in our battery tests. That’s a slight edge to the pair of devices if the Duo is only used folded, and a resounding win if unfolded.
Better camera power
For a flagship device, the iPhone Duo is surprisingly under-specced in the camera department. There are two 48MP rear cameras: a f/1.6 main lens and a f/2.2 ultrawide.
While the iPad mini’s camera can be safely ignored for the most part, the iPhone 18 Pro is clearly far more flexible. Not only does the 48MP main camera include a variable aperture, letting photographers choose between f/1.48m, f/1.8m f/2.8 and f/4.0 values, but you also get an additional 48MP telephoto lens with 4x optical zoom.
A full Apple Pencil experience
Although the iPhone Duo supports the Apple Pencil on both of its screens, there is one big caveat: you have to use the paired-back USB-C version. That means there’s no pressure sensor, haptic feedback, Find My support or added features like squeeze or double-tap.
While that’s better than the iPhone 18 Pro, which doesn’t support any Apple Pencils, the iPad mini 7 lets you use the USB-C model or the far better Apple Pencil Pro. That makes it the superior option for serious doodlers.
iPhone Duo or iPhone 18 Pro + iPad mini?
Ultimately, there are benefits to both configurations. The iPhone Duo is undoubtedly more convenient and portable than lugging around two devices, and it has a few neat features that aren’t (yet) available on other Apple handhelds, like the under-screen selfie camera and a matte display.
But opting for both a less glamorous iPhone and iPad instead will save you at least $200, and likely more if you shop around or look beyond the brand new iPhone 18 Pro. On top of that, you get a superior camera setup and the full Apple Pencil experience.
In short, there’s no straightforward right or wrong answer here, and what you should choose will depend on your budget and specific circumstances.
