As an Amazon Associate I earn from qualifying purchases. This post contains affiliate links.

Apple finally made a foldable. The iPhone Duo goes on sale October 23, 2026, and the obvious question is how it stacks up against the phone that's owned this category for years: Samsung's Galaxy Z Fold 8.

Here's the short answer:

If you already use an iPhone, buy the iPhone Duo.

If you want the lightest, most flexible foldable for less money, buy the Galaxy Z Fold 8.

The Duo is tougher and better integrated. The Fold 8 is thinner, lighter, cheaper, and better at multitasking.

Price

Neither phone is cheap.

• iPhone Duo: from $1,999 for 256GB, with 512GB, 1TB, and 2TB options
• Galaxy Z Fold 8: from $1,899.99 for 256GB, with 512GB and 1TB options

That's about a $100 difference at the base level. Samsung also runs frequent trade-in deals and discounts, so in practice the gap is often bigger.

Winner: Galaxy Z Fold 8

---

Design & Size

Both phones open into a 7.6-inch screen, but they feel different in the hand.

The iPhone Duo uses a wide, "passport-style" shape. Closed, its 5.4-inch outer screen is shorter and wider than a regular phone. It's built from grade 5 titanium with a titanium-and-aluminum hinge. It's also heavy: 254 grams and 11.3 mm thick when folded.

The Galaxy Z Fold 8 is noticeably slimmer: 201 grams and 9.7 mm folded, and just 4.5 mm open. That's about the weight of a regular large phone, which matters a lot when you carry it all day.

If pocketability is your priority, Samsung wins clearly.

Winner: Galaxy Z Fold 8

---

Durability

Foldables have always been more fragile than regular phones, so this category matters.

The iPhone Duo is rated IP68, meaning it's protected against both dust and water. It also uses Ceramic Shield on the outside and a scratch-resistant coating on the inner screen.

The Galaxy Z Fold 8 is rated IP48. It's water-resistant, but the "4" means only limited protection against dust and sand — the classic weak spot for foldable hinges.

If you're hard on phones, or spend time at the beach, this is a real advantage for Apple.

Winner: iPhone Duo

---

Screens

Both inner screens measure 7.6 inches and refresh at up to 120Hz, and both are very bright.

The Duo adds a matte "nano-texture" finish to cut glare, plus Apple Pencil support on both screens (Apple says this is coming later this year). The Fold 8's outer screen is a touch larger at 5.5 inches and uses a taller shape that feels more like a normal phone when closed.

Early coverage suggests the Duo's crease is less visible, but we'll wait for more hands-on testing before calling that.

Winner: Tie

---

Cameras

On paper these are close. Neither phone has a dedicated telephoto lens.

• iPhone Duo: 48MP main, 48MP ultrawide, up to 2x optical-quality zoom, 4K video at 120fps
• Galaxy Z Fold 8: 50MP main (with optical stabilization), 50MP ultrawide

The Duo has a few clever tricks: the outer screen can show people a preview of the shot you're taking, and FaceTime can show your face and the outer camera's view at the same time.

Apple and Samsung both make excellent cameras, and the Duo is too new for fair side-by-side tests. For now, this is a draw.

Winner: Tie (for now)

---

Battery & Charging

The batteries are almost the same size: 4,883 mAh for the Duo versus 4,800 mAh for the Fold 8.

Apple claims up to 31 hours of video playback on the inner screen and 44 hours on the outer one, plus about a 50% charge in around 20 minutes. It also supports MagSafe, so your existing iPhone chargers and accessories work.

Independent battery tests of the Duo aren't out yet, so we'll update this section when they are.

Winner: Too early to call

---

Software & Multitasking

This is where your current phone matters most.

The iPhone Duo runs iOS 27 with a new layout made for the bigger screen: two apps side by side, Safari with two windows, and a "half-folded" mode that adjusts apps to the hinge angle. It works seamlessly with iMessage, AirDrop, your Apple Watch, and your Mac. One early gap: left-handed reachability features aren't available at launch.

The Galaxy Z Fold 8 runs Android with Samsung's multitasking tools, which are more advanced after eight generations: up to four windows at once, plus floating app windows. Power users who live in multiple apps will feel more at home on Samsung.

Switching between iPhone and Android is still a hassle, so for most people the right answer is whichever system you already use.

Winner: Galaxy Z Fold 8 for multitasking, iPhone Duo for Apple users

Final Verdict

These are the two best foldables you can buy, and they suit different people.

Pick the iPhone Duo if you're already an iPhone user, want the most durable foldable, or want Apple Pencil support. It's heavier and costs more, but it's the first foldable that fits into the Apple world without compromise.

Pick the Galaxy Z Fold 8 if you use Android, care about weight and thickness, or want the best multitasking. It's lighter, slimmer, and $100 cheaper, and Samsung has had eight generations to refine it.
