Xiaomi 18 Fold review: 7.58-inch inner screen and 6,000mAh stamina

At first glance, the 18 Fold feels different from many foldables on the market. It uses a passport-style outer display, which means you can use it like a regular smartphone when it’s closed, but you open it up to reveal a 7.58-inch inner screen. The inner display has a roughly 2:1 aspect ratio, giving you a broad canvas for multitasking and media. The phone also includes a large 6,000mAh battery and fast charging options (67W wired and 50W wireless in the hardware notes), which translates to real-world endurance in daily use.

When folded, the 18 Fold is about 219g and 10.68mm thick. Those figures place it in the thicker, heavier end of the foldable spectrum, but the reviewer notes that the extra heft never feels oppressive in everyday use. The cherry red finish stands out and helps this model feel more distinctive than the usual black slab that dominates premium devices. The build prioritizes battery and internal hardware over shaving millimeters, a choice that pays off in how the device feels in the hand.

The device ships with a HyperOS 4 software layer that enables features like running multiple apps on the inner screen with floating windows. In practice, that multitasking is impressive in concept, but you’ll likely settle into using two or three apps at once rather than six. App optimization varies, some apps adapt smoothly to the foldable format, others do not, highlighting a familiar issue in foldables: software needs time to catch up with hardware capabilities.

Right now, the Xiaomi 18 Fold is a China-only device. That means questions about local support, warranty coverage, and how easy it is to bring the phone to the US, UK or Canada aren’t answered in a broad, official way. For readers outside China, that makes the 18 Fold a compelling concept device rather than a practical everyday upgrade right now.

Foldables are inching closer to being genuinely usable as daily drivers, not niche gadgets. The Xiaomi 18 Fold showcases how big its inner display can be while still folding into a form that’s comfortable to carry. If you’re curious about the next wave of smartphones, this model points to a future where large screens and long battery life come together in a more portable package. But until software supports more apps and better optimization, the user experience can feel a step behind the hardware.

If Xiaomi follows its usual pattern, we could see updates aimed at improving app compatibility and multitasking workflows in subsequent software releases. For readers in the US, UK, or Canada, the key question is whether Xiaomi expands availability beyond China; there’s no official word yet about a global rollout.
