Apple has finally made a folding phone, and it’s called the iPhone Duo. If you’ve been holding off on upgrading because you wanted to see what Apple’s version of a foldable would actually look like, the wait is over. Below is a plain-English look at what the iPhone Duo is, what it can do, and exactly how much it’ll cost you.
What Is the iPhone Duo?
The iPhone Duo is Apple’s first-ever folding phone. The design is reminiscent of a smaller book, which acts as a phone with a front-facing screen when closed but transforms into a much larger display when opened up, similar to a small tablet in size. This product was unveiled at Apple’s “Surprise and Shine” event with the iPhone 18 Pro and iPhone 18 Pro Max, with the Duo representing an upgrade over the standard models as a new flagship product rather than a replacement.
Apple has eschewed their usual name for this product that is both elegant and short, going with a much more mundane-sounding name that represents the dual nature of the product, suggesting that consumers are getting two products in one.
Design and Displays
Open up and it’s an impressive 7.6 inches, claims Apple, which is its largest ever iPhone display and offers more than 50% extra screen space over the iPhone 18 Pro Max. Closed, it’s a more compact 5.4 inches – providing over 90% of the screen area of a regular iPhone 18 Pro, meaning it’s a more practical everyday phone than a compromised phablet.
As it doesn’t support Face ID, the iPhone Duo uses Touch ID, but Apple has put the fingerprint scanner on the side button, rather than the home button, due to the way the display folds. The screen uses a nano-textured surface to reduce reflections and hide the crease in the middle of the display.
It’s available in two colours at launch, Star White and Night Sky, with no price difference between any of the storage capacities.
Camera and Chip
The iPhone Duo is powered by Apple’s new A20 Pro chip found on the iPhone 18 Pro. The new SoC uses a more efficient two nanometer process than the previous generation. While some of the competition’s folding phones use last year’s chip in order to cut costs, Apple does not appear to be doing the same.
For cameras on the device, there is a main 48 megapixel sensor and a 48 megapixel ultra-wide angle camera on the back of the device. There is no telephoto lens, meaning the maximum level of magnification is four times optical and ten times digital, making it an area where the standard iPhone 18 Pro has the advantage. However, the flexible nature of the phone does introduce some unique features including Smart Take that snaps a picture of everyone once they are all in frame, a Duo Preview function that allows the subject of a photo to see themselves on the outside of the folded phone, and a Duo FaceTime function that allows someone nearby to jump right into a video call using the outside display.
Battery Life
Due to powering two displays, Apple made a decision to equip the device with a dual battery. According to the company, the battery capacity is enough for 24 hours of absolute usage or 44 hours of video playback on one outer screen on a full battery. A 60-watt charger will charge the iPhone Duos from 0 to 50 percent in about 20 minutes. Besides, the device is compatible with MagSafe and Qi2 wireless charging, which can provide up to 25 watts of power.
How Much Does the iPhone Duo Cost?
Here’s the bit most people actually want to know:
| Storage | US Price | UK Price |
| 256GB | $1,999 | £1,999 |
| 512GB | $2,199 | £2,199 |
| 1TB | $2,599 | £2,599 |
| 2TB | $3,199 | £3,199 |
That entry price is around $700/£700 more than the iPhone 18 Pro Max at the same storage level, so you’ll be paying a premium for the folding screen and hinge, not an upgrade in the cameras.
If you want something cheaper to spread them payments out, Apple also has installments that you can choose. In the US it would be $$83.29 a month over 24 months, or an Apple Upgrade lease starting from $57.99, while in the UK Apple offers financing over 30 months with 0% APR, which would see you paying £66.63 a month for the 256GB model, and £106.63 a month for the 2TB variant.
iPhone Duo vs iPhone 18 Pro Max
If you’re thinking about these two options, you should know what to choose based on what you really need in a phone. The iPhone 18 Pro Max is cheaper, uses a proper telephoto zoom lens, and is the right size to fit in any pocket. The iPhone Duo would be more expensive, have no zoom lens, and have a massive display to read or watch videos or have two apps open at once side by side – which is perfect if you want to use your phone for work as well as for texts and photos.
