iPhone Duo vs Samsung Galaxy Z Fold8: Which Foldable Should You Buy?
Apple's first foldable takes on Samsung's lightest Fold yet. We compare price, screens, chips, cameras, battery and software to help you choose.
For years, Samsung had the big-screen foldable market almost to itself. Now Apple has arrived with the iPhone Duo, going head-to-head with Samsung's Galaxy Z Fold8. Both open from a phone into a 7.6-inch mini tablet — but they're built on very different ideas.

Battery life figures are each company's own claims and are measured differently, so they aren't a direct comparison.
Design and screens
Both phones use a 7.6-inch inner display, with near-identical outer screens (5.4 inches on the iPhone, 5.5 on the Samsung). Samsung says the Fold8 is its lightest Fold yet at 201g, and just 4.5mm thin when open. Apple says the iPhone Duo is the thinnest iPhone it has ever made when opened.
Performance
Both use top-tier chips: Apple's new A20 Pro and Qualcomm's Snapdragon 8 Elite Gen 5 for Galaxy. Either will handle anything you throw at it. The bigger differences are in software and ecosystem.
Cameras
The iPhone Duo uses a 48MP Fusion main camera and hides a FaceTime camera under the inner display, with a clever Duo FaceTime feature for calls through the outer screen. The Fold8 has a 50MP main and 50MP ultrawide camera, but no telephoto lens — for zoom, Samsung's pricier Fold8 Ultra adds a 200MP main camera and a 3x telephoto.
Battery and charging
Apple uses a dual-battery design spread across both halves, while Samsung uses a 4,800mAh battery with 45W wired charging plus wireless and reverse wireless charging. Real-world battery tests will tell us more once the iPhone Duo is in reviewers' hands.
Software and support
iOS 27 has been redesigned for the iPhone Duo's wide screen, and it's the obvious choice if you use a Mac, iPad or Apple Watch. The Fold8 runs Android 17 with One UI 9, and Samsung has years of experience making apps and multitasking work well on foldables.
One practical note: the iPhone Duo is eSIM-only, so check that your carrier supports eSIM.
Which should you buy?
- Buy the Galaxy Z Fold8 if you want a proven foldable you can buy today, for $100 less, with Samsung's mature multitasking.
- Buy the iPhone Duo if you're committed to Apple's ecosystem and want Apple's first take on the folding phone — ideally after the first reviews arrive around October 23.
- Want the best cameras? Look at the Galaxy Z Fold8 Ultra ($2,099) with its 200MP main and 3x telephoto.
