Xiaomi has launched the Xiaomi 18 Fold, the company’s first device in a new “mid-folding” form factor. It was launched alongside Xiaomi 18 Pro series smartphones. The exciting foldable gadget brings a larger inner display while retaining a conventional-looking outer screen, and features Xiaomi’s new XRing O3 flagship chipset.
Xiaomi 18 Fold takes a different approach. It doesn’t feature a book-style design that uses a tall outer screen and a wider inner panel. The company calls the new design “mid-folding,” with the phone using a 5.38-inch outer display and a 7.58-inch foldable inner display. The device competes with Apple’s iPhone Duo and Samsung’s Galaxy Z Fold8.
Xiaomi 18 Fold Overview
7.58-inch foldable display and design
The Xiaomi 18 Fold features a 5.38-inch cover display and a 7.58-inch internal main display. The two screens use a 2:1-style aspect ratio, allowing the unfolded display to provide a more tablet-like experience.
Xiaomi says the design is intended to make multitasking more practical. The inner screen can be divided into multiple sections, allowing users to run applications side by side.
The foldable phone is essentially designed to remain slim. Xiaomi’s three-link hinge design enables the device to measure just 5.02mm when unfolded, according to Xiaomi’s published specifications.
Xiaomi 18 Fold uses a three-link hinge and a strengthened internal structure. Xiaomi says its dual-layer ultra-thin glass structure improves the durability of the inner display, while the redesigned hinge helps reduce the visible crease. The phone uses a P58/IP59 certification for dust and water protection.
It is available in Nishino Red, black, and a warm gold/white finish.
Powered by Xiaomi XRing O3
The Xiaomi 18 Fold is the first smartphone to launch with Xiaomi’s new XRing O3 flagship processor. The chipset is manufactured using a 3nm process and features a 10-core all-big-core CPU architecture. The Xiaomi 18 Pro series runs on new Snapdragon 8 Elite 6 chipsets, though.
Xiaomi says the XRing O3 CPU delivers a 60% performance improvement over the previous generation, while its new G2-Ultra NX GPU provides a major graphics performance increase with lower power consumption.
The XRing O3 also brings a new NPU architecture focused on on-device AI processing. Xiaomi has positioned the processor as a major part of the 18 Fold’s AI capabilities.
The Xiaomi 18 Fold is also the first mobile device to introduce LPDDR6 RAM to the market. The phone is available with up to 16GB of RAM and 1TB of storage, with the 1TB version using LPDDR6 memory. LPDDR6 memory technology helps the foldable handle demanding applications and multitasking.
