Apple’s first foldable, the iPhone Duo, is one of the best first-generation foldables I’ve seen in a while, though that’s also because almost every other major smartphone manufacturer has one and Apple is exceptionally late to the party. Arriving roughly two months after the Samsung Galaxy Unpacked event, the Duo, through no fault of its own, competes directly with the Galaxy Z Fold 8. 

Given that the phones share a similar design philosophy and price bracket, you’re bound to ask which one is the better pick between the two. In this comparison, I’ve tried to break that down, focusing on the practical aspects that shape your day-to-day experience with foldables rather than the spec sheet. Take a look at the hardware differences below, then dive into the real-world differences.

iPhone Duo vs. Galaxy Z Fold 8: Specs at a glance

iPhone Duo: A well-hidden hinge, unique iOS 27 experiences, and IP68 durability

This is Apple’s first foldable iPhone, but that doesn’t mean it has experimental first-generation elements. Everything about the iPhone Duo screams sophistication. Talk about the screen, for instance. The glossy cover screen looks vibrant, but only when you open the Duo do you realize how much attention Apple paid to the details. 

The iPhone Duo’s seamless hinge comes from a three-part system: a nano-texture matte layer that cuts through reflections and glare, a stack of glide-adhesive glass layers, and a titanium backing plate that lets each layer flex independently. It’s not like the crease isn’t there or isn’t visible at all, but it doesn’t fight you the way it does on most rivals, including the Fold 8. 

It’s an irony that the foldable iPhone is actually slimmer than the iPhone Air when unfolded. However, the Fold 8 is even slimmer, something that I’ll come to in a bit. Irrespective of its thickness, it’s the aspect ratio that does the convincing, especially for buyers who’re sick of the black bars at the top and the bottom of a Netflix show or YouTube video. 

While I’m not able to look past the straight edges on the left as opposed to the rounded corners on the right of the cover screen, it’s the opening animation, fading and blurring out the content on the cover screen, then slowly appearing on the inner screen, that makes opening the Duo feel less like switching screens and more like transforming the small phone into an iPad. 

That’s how iOS 27 treats the two screens as one connected surface, scaling the apps from the outer to the inner screen. Then there are Duo-specific features. Split View, for instance, lets you run two apps side by side or two windows of the same app, save those pairs, and keep a Siri AI conversation going next to whatever you’re looking at. 

However, Samsung has had mature multi-window and Flex Mode on its foldables for years, so this is Apple playing catch-up rather than leading.

Controls, Dock, and the Dynamic Island slide aside. Later this year, both displays will accept an Apple Pencil, turning the inner screen into a genuine writing and markup surface, something that Samsung has ignored entirely for its foldables. 

While the dual 48MP camera system sounds boring on paper, Apple has put real effort into making it, well, slightly less boring. Smart Take watches the scene and fires the shutter the moment your subjects actually look ready. Duo Preview turns the outer display into a live viewfinder, while Kid Cue plays cartoons on the cover screen to hold a toddler’s attention long enough to get the shot.

Duo FaceTime lets someone standing next to you join the call on the outer display without crowding around one screen. None of these dual-screen camera tricks exist on the Fold 8.

I’m including these features so you’re aware of the experience Apple’s foldable provides. Powering all those features is a new 2nm chipset called A20 Pro, a highly efficient and powerful chipset, something that the Galaxy Z Fold 8 doesn’t get this generation. 

Add full IP68 protection (superior to the Fold 8’s IP48 rating), Apple’s first under-display selfie camera, Touch ID that works whether the phone is open, closed, or mid-fold, and a unique StandBy implementation, and you get a device engineered around one idea: a foldable shouldn’t feel like a compromise you’ve agreed to tolerate.

Galaxy Z Fold 8: A slimmer and lighter wider fold that disappears into your pocket

The Fold 8 shares its form factor with the iPhone Duo. But the execution differs. Samsung’s Fold weighs 201 grams versus the Duo’s roughly 254 grams. That’s not a rounding error, but the difference between a foldable that feels like a regular phone and one that starts feeling too heavy in your jacket pocket. 

Dimensions are the same story. At 9.7 mm folded and just 4.5 mm when open, it slips into a pocket the way a normal phone does, thinner when opened than the Duo and meaningfully lighter when closed. Samsung didn’t get there by cutting corners, but by cutting low-quality components and replacing them with a titanium-alloy film and titanium plate under the display, what it calls the Flex Titanium hinge. 

The crease is genuinely less visible than previous Samsung foldables, but Apple’s first-generation foldable has definitely done a better job here. Both the cover display and the inner screen have a similar size and aspect ratio as the iPhone Duo. However, despite the Galaxy S26 Ultra’s built-in stylus, the Galaxy Z Fold 8 lacks stylus support entirely. 

Combine that with the Snapdragon 8 Elite Gen 5 for Galaxy (and up to 16 GB of RAM on the top model), One UI 9’s three-app split view (against Apple’s two-app split view), floating windows, Flex Mode’s half-folded controls-on-bottom layout for hands-free video calls, and, most importantly, full Samsung DeX desktop output, and the Fold 8 pitches itself better as a productivity machine. 

You don’t get such features on the iPhone Duo. You also don’t get Google’s Gemini AI assistant with Gemini Intelligence for agentic abilities, plus features like Now Nudge, Photo Assist, and other Galaxy AI features. Unlike Apple, Samsung also commits to seven years of operating system and security updates, so long-term buyers should rest assured. 

Battery life is rather strong on the Fold 8. The phone provides around seven to eight hours of screen-on time with mixed usage. However, the lack of magnetic wireless charging on the foldable is my real gripe with Samsung. Apple’s iPhone Duo has it, Google’s Pixel 11 Pro Fold has it, but none of the latest Galaxy flagships do. 

Ultimately, the Galaxy Z Fold 8 excels with its design and hardware. Samsung’s years of experience making foldables really show in ways an average customer notices day to day. It doesn’t take much effort to get used to, especially for someone who’s used a Samsung phone or a foldable before, and that’s the real deal for me. 

iPhone Duo vs. Galaxy Z Fold 8: Which one should you choose?

Even though both phones follow the shorter-and-wider design philosophy, they’re not chasing each other. Each has its pros and cons, and there’s no one superior pick between the two. The easiest answer is your choice of operating system or ecosystem. For Apple users, iPhone Duo is the only option. For Samsung users, the Fold 8 is an excellent choice (though the conversation widens a bit when you consider Android foldables).
