Fold 8 vs iPhone Duo: price and storage
The Galaxy Z Fold 8 starts at $1,899 in the US, which is $100 less than the iPhone Duo at $1,999.
However, storage options differ. Samsung sells 256GB, 512GB and a 1TB model with 16GB of memory. Apple goes further, with 512GB, 1TB and even a 2TB version.
Outside the US, the gap can grow much wider, so check local prices before you decide. For example, the Fold 8 starts at Rs 1,79,999 in India.
Design and build
Both phones use the new wide, passport style shape.
Even so, the build is very different. The Fold 8 uses an aluminium frame and weighs only 201 grams, which makes it Samsung’s lightest Fold yet. In contrast, the iPhone Duo uses a titanium frame and weighs 254 grams. You will feel that 53 gram gap every day.
Durability favours Apple. The iPhone Duo is rated IP68, so it handles water and dust well. The Fold 8 is rated IP48, which means good water protection but weak dust protection.
Both phones use a fingerprint sensor in the side button. For Apple, that means Touch ID returns and Face ID is missing on the Duo.
Fold 8 vs iPhone Duo screens
On paper, the screens are almost equal. Each has a 7.6 inch inner display with a 120Hz refresh rate and a peak brightness of up to 3,000 nits.
The small differences come from design choices. Apple hides the inner selfie camera under the screen, so nothing breaks up the view. Samsung uses a hole punch camera inside, but it gives you a slightly bigger 5.5 inch cover screen.
Both brands say their crease is less visible than before. In addition, reports say Apple Pencil support is coming to the Duo with iOS 27.2, while Samsung dropped S Pen support on its Fold line.
AI features and software
The iPhone Duo runs iOS 27 with Siri AI, which can use what is on your screen and your personal context. It also has Smart Take, which uses on device AI to snap a photo at the right moment. You can read more in our guide to iPhone Duo AI features.
Meanwhile, the Fold 8 runs One UI 9 on Android 17 with Galaxy AI. You get tools like Now Brief and Photo Assist, plus stronger multitasking. You can run three apps side by side, open floating windows and plug into a monitor with Samsung DeX. Samsung also promises up to seven years of Android updates. Our One UI 9 update guide covers the new features in detail.
As a result, the Fold 8 suits people who use their phone like a laptop.

Fold 8 vs iPhone Duo cameras
Neither phone is a camera king. Both skip a telephoto lens, so zoom shots are weaker than on top regular phones.
Still, both shoot good everyday photos. The Fold 8 has a 50MP main and 50MP ultrawide camera, and it records 8K video at 30fps. The iPhone Duo has a 48MP main and 48MP ultrawide camera, and it tops out at 4K, but at a smooth 120fps. For selfies, the Duo uses a 12MP camera and the Fold 8 a 10MP cover camera.
Battery and charging: Fold 8 vs iPhone Duo
Samsung lists a 4,800 mAh battery for the Fold 8, with 45W wired and 20W wireless charging. However, the Fold 8 has no built in magnets, so you need a magnetic case for Qi2 chargers.
Apple does not promote the Duo’s battery size, although reports citing an EU energy label put it at 4,883 mAh. On the other hand, it supports 60W wired charging, the fastest on any iPhone, and 25W MagSafe. Early reports say a 60W charger fills 50% in about 20 minutes.
Repairs and early reports
Foldables cost more to fix, so plan for it. Some early iPhone Duo owners have reported inner screens breaking near the hinge, and Apple charges a high fee for an inner display out of warranty. See our full breakdown of iPhone Duo screen repair cost before you buy.
