Xiaomi 18 Fold vs iPhone Duo: Specs, Price & Full Comparison 2026 | BluePages

The Xiaomi 18 Fold vs iPhone Duo comparison brings together two of the most talked-about foldable smartphones of 2026.

Both phones use a wide, book-style foldable design, but they take different approaches to hardware, cameras, software, battery, design and overall user experience.

Xiaomi has focused heavily on hardware specifications, while Apple has combined its first foldable design with the A20 Pro chip, iOS 27 and its wider ecosystem.

So, Xiaomi 18 Fold vs iPhone Duo — how different are these two foldables?

Let's find out.

📱 Xiaomi 18 Fold vs iPhone Duo: Quick Comparison

*Reported capacity; Apple officially describes the iPhone Duo as using a dual-battery architecture.
