Apple iPhone Duo vs. Samsung Galaxy Z Fold 8: It comes down to just one thing

Apple iPhone Duo vs. Samsung Galaxy Z Fold 8: Pricing and availability

The iPhone Duo made its debut at Apple's launch event on September 9, 2026. The foldable starts at $2,000 in the U.S., but you'll be paying closer to $2,700 in most countries around the world — it is launching in 70 markets globally on October 16.

Samsung unveiled the Galaxy Z Fold 8 on July 22, 2026, and the foldable retails at $1,899. This is the base model with 256GB of storage, and there's also a 512GB edition that costs $2,099 in the U.S., and a 1TB model that is $2,499.

Apple iPhone Duo vs. Samsung Galaxy Z Fold 8: Design

The iPhone Duo is different to every other iPhone thus far, with the foldable design ushering in an entirely new form factor for iOS. The iPhone Duo has a similar wide-and-short configuration as the Galaxy Z Fold 8, and the passport-style design is definitely intriguing — there's no wonder that other Android manufacturers are emulating a similar style.

It has a 5.4-inch cover panel and a 7.6-inch inner panel, and the iPhone Duo is 5.2mm while unfolded, making it a little thicker than the Z Fold 8 and other Android foldables. That said, the weight at 254g makes it one of the heaviest foldables around, and it is 15g heavier than the Pixel 11 Pro Fold. The design looks a lot like the Pixel 11 Pro Fold, with rounded edges and a flatter profile along the hinge. While Apple introduced a bright burgundy color with the iPhone 18 Pro, the iPhone Duo is sold in white and blue models.

Just like Android foldables, the iPhone Duo gets Touch ID housed within the power button as the standard mode of authentication instead of Face ID. The Z Fold 8 gets a 5.5-inch cover panel and a 7.6-inch inner screen, and Samsung managed to deliver IP48 dust and water resistance. By contrast, the iPhone Duo has IP68 dust and water resistance, giving it a distinct advantage.

Interestingly, one of the biggest selling points of the iPhone Duo is the display crease. The Find N6 and Vivo X Fold 5 do a fabulous job in this regard — they're better than the Galaxy Z Fold 8 and Fold 8 Ultra — and with the iPhone Duo using two layers of ultra-thin glass and a liquid-metal hinge, Apple's foldable has a creaseless design, outshining Samsung's Z Fold 8 in this key area.

Apple iPhone Duo vs. Samsung Galaxy Z Fold 8: Hardware

The iPhone Duo has the biggest battery of any iPhone, and that in itself is exciting. There is a 4,700mAh battery, and that's similar to what's available on the Z Fold 8. That said, iOS has much better efficiency in general, so the iPhone Duo should have better battery life, and with Apple switching to a 2nm node, battery life will get an additional boost.

Wide foldables are smaller than book-style devices like the Galaxy Z Fold 8 Ultra, and as a result, Samsung just went with two cameras on the Galaxy Z Fold 8: a 50MP main camera and 50MP wide-angle lens.

The iPhone Duo uses a similar arrangement, and it gets two 48MP cameras, without a dedicated tele lens. There are a lot of interesting camera features with the foldable, but the tele lens is the one I use the most, and not adding that is a big omission on both devices.

Apple iPhone Duo vs. Samsung Galaxy Z Fold 8: Software

Software makes a big difference on a foldable, with the added real estate ideal to multitask. This is a priority in iOS 27, and there's no doubt that the iPhone Duo has what is arguably one of the most well-thought-out interface design of any foldable.

The taskbar and other UI elements are located on the right to maximize real estate, and it has smooth animations that other brands should immediately steal. You get split-screen multitasking similar to the iPad, and while Samsung offers a lot of the same features, I get the feeling that the iPhone Duo has it beat in this area.

Apple iPhone Duo vs. Samsung Galaxy Z Fold 8: Which should you buy?

While foldables have been around for the better part of a decade now, they're still pretty niche. That changes with the introduction of the iPhone Duo; say what you will about Apple, but the brand has an unmatched ability to grab attention, and interest in foldables has skyrocketed following the iPhone Duo launch.

Now, whether this will translate to sales is another thing entirely, but if you're an iPhone user and wanted to switch to a foldable, the iPhone Duo is the obvious choice. While Samsung got a lot right with the Z Fold 8, it doesn't do nearly enough to convince iOS users to move to Android in any meaningful numbers.
