Galaxy Z Fold 8 vs iPhone Duo: Specs, Design, Price, and Key Differences

Samsung's Galaxy Z Fold 8 became available in August 2026. Apple followed on September 9 by officially introducing its first foldable iPhone, the iPhone Duo, with availability beginning October 23.

That gives shoppers two premium book-style foldables to consider and gives online retailers another major accessory launch to prepare for. Here's how the confirmed Galaxy Z Fold 8 vs iPhone Duo specifications compare.

Galaxy Z Fold 8 vs. iPhone Duo: Quick Comparison

Design

Both devices use a book-style fold, but their proportions and construction differ. The Galaxy Z Fold 8 weighs 201 grams and measures 4.5mm thick when unfolded. Its redesigned proportions give users a wider cover screen than previous Fold generations.

Apple's iPhone Duo fold specs include a Grade 5 titanium design and a precision-engineered hinge. At 254 grams, the Duo is heavier than Samsung's Fold8. It measures 5.2mm thick when open and 11.3mm when closed. Apple also uses Touch ID in the side button rather than Face ID.

Those differences mean cases need to be designed specifically for each model.

Display

Both phones open to a 7.6-inch main display. The Fold 8 pairs that with a 5.5-inch cover screen, while the iPhone Duo has a 5.4-inch outer display.

Apple uses Super Retina XDR OLED displays with ProMotion up to 120Hz on both screens. The inner screen also has a nano-texture finish designed to reduce glare. Samsung's 7.6-inch main screen uses a 4:3 aspect ratio and includes an anti-reflective treatment.

Camera

The Fold 8 has two 50MP rear cameras: a Wide and an Ultra Wide. It also has a 10MP cover camera and a 10MP under-display camera.

Apple equips the Duo with a 48MP Fusion Main and 48MP Fusion Ultra Wide camera. The Main camera also provides a 2x optical-quality telephoto option. There's also an under-display camera for FaceTime beneath the inner display.

The hardware is different enough that shoppers should consider the entire camera system rather than comparing megapixel numbers alone.

Battery Life & Charging

Samsung lists a 4,800mAh typical battery for the Galaxy Z Fold 8 and rates it for up to 26 hours of video playback.

Apple doesn't provide an mAh capacity for the Duo. It uses two built-in rechargeable batteries and is rated for up to 44 hours of video playback using the outer display or 31 hours using the inner screen. When both displays are used equally, the Duo delivers up to 24 hours of battery life per charge. It also supports MagSafe and Qi2 wireless charging up to 25W.

Performance and Software: Android vs. iOS

The Fold 8 runs on the Snapdragon 8 Elite Gen 5 for Galaxy and offers Samsung's foldable Android experience, including Multi Window, Samsung DeX, and Galaxy AI features.

The Apple iPhone foldable uses the A20 Pro chip. Apple has adapted iOS 27 for the foldable format, with multitasking features designed to take advantage of the larger inner display.

For many buyers, the software ecosystem may matter as much as the hardware. Android users get Samsung's established foldable platform, while iPhone users now have their first foldable option within Apple's ecosystem.

What the Galaxy Z Fold8 and iPhone Duo Mean for Online Sellers

Two new foldables are giving the accessory market plenty to watch this season.

The Galaxy Z Fold 8 is already in stores, bringing a new generation of Samsung's foldable range to shoppers. That creates demand across the usual essentials, from cases and screen protection to accessories that fit naturally into everyday use.

Then comes the iPhone Duo. Apple's first foldable iPhone arrives on October 23, bringing the foldable format to a much broader iPhone audience. For retailers, it is another chance to refresh their assortment around one of the year's biggest device launches.

The interesting part is how the two launches complement each other. Samsung has already opened the door to this new accessory cycle, while Apple is about to bring another large customer base into it.

Two Foldables, Two Ecosystems
