Xiaomi 18 Fold 5G Foldable Smartphone – CN Version

• This is a Chinese edition, and only supports the English/Chinese menu.
• This smartphone is pre-installed with full Google Mobile Service, and with Google Play Store, OTA updating is supported.

The Xiaomi 18 Fold is a premium book-style 5G foldable smartphone powered by Xiaomi’s new 3nm XRING O3 flagship processor and Xiaomi HyperOS 4. It features a compact 5.38-inch outer AMOLED display and a large 7.58-inch foldable AMOLED inner display, both supporting a smooth 120Hz refresh rate. The new wide-format design is optimized for one-handed use when folded and for multitasking, entertainment and productivity when fully opened.

This brand-new Xiaomi 18 Fold CN Version features a Leica professional triple-camera system led by a 200MP main camera, together with 50MP telephoto and 50MP ultra-wide cameras. It also packs a large 6000mAh silicon-carbon battery with 67W wired and 50W wireless charging, while Xiaomi’s redesigned Dragon Bone hinge and dual-layer UTG display structure improve durability in everyday use. Available from IVORION with worldwide shipping.

Why choose Xiaomi 18 Fold?

• A 5.38-inch cover screen opens into a 7.58-inch AMOLED display, both with adaptive refresh rates up to 120Hz.
• Xiaomi XRING O3 combines a 3nm process, 10-core CPU and 16-core GPU.
• Leica imaging pairs a 200MP main camera with 50MP periscope and ultra-wide cameras.
• A 6,000mAh typical battery supports up to 67W wired and 50W wireless charging with the required accessories.
• The three-link hinge and dual-layer UTG support the foldable display structure.
• HyperOS 4 supports flexible multitasking with up to six split-screen applications.

A compact cover screen with room to unfold

Xiaomi 18 Fold brings a different set of proportions to the foldable phone. Its 5.38-inch cover display provides a compact surface for everyday interactions, while opening the device reveals a 7.58-inch inner screen for reading, viewing and working across applications. Both displays combine a full RGB pixel arrangement with adaptive refresh rates up to 120Hz. IVORION offers the CN Version, with the verified memory and finish choices available through the product selectors.

A folding structure built around the display

The new Xiaomi hinge uses a three-link mechanism to support the screen when open and create space for it when closed. The inner display incorporates two UTG layers, while the cover display uses Xiaomi Shield Glass 3.0. Standard colors pair a glass back with an aluminum-alloy frame; the pink Ceramic Special Edition uses a silicon nitride ceramic back. The factory-applied inner film should remain in place, with replacement handled by a qualified service provider.

XRING performance with configuration-specific memory

The Xiaomi XRING O3 is built on TSMC’s 3nm process and combines a 10-core CPU, a 16-core G2-Ultra NX GPU and a four-core NPU. A ring-shaped cooling system helps move heat away from working components. Memory technology depends on the chosen configuration: the 12GB models and 16GB/512GB model use LPDDR5X, while 16GB/1TB uses LPDDR6. Every listed configuration uses UFS 4.1 storage, with usable capacity reduced by the system and installed software.

Leica cameras for wide scenes and closer framing

The rear system covers three useful perspectives: a 200MP main camera, a 50MP periscope telephoto camera and a 50MP ultra-wide camera. Optical stabilization supports the main and telephoto cameras, while the telephoto provides 3.5× optical zoom. Leica photographic styles and manual shooting tools give you different ways to approach a scene. For customers comparing foldable camera systems, IVORION presents the published camera specifications below, including the supported recording resolutions and frame rates.

Battery capacity with wired and wireless options

A 6,000mAh typical-capacity battery sits inside the folding body, with a published minimum/rated capacity of 5,875mAh. The phone supports Xiaomi wired charging up to 67W and wireless charging up to 50W, alongside PD and PPS charging protocols. Reaching the stated Xiaomi charging rates requires the compatible charging accessories specified below. The USB-C port also supports fast USB 3.2 Gen 2 data transfers, but that function needs a separately purchased USB 3 cable.

More flexible workspaces in HyperOS 4

HyperOS 4 supports adjustable split-screen arrangements with up to six applications, providing space to compare information or move between tasks. Xiaomi highlights desktop-style applications adapted for the wider inner display, together with Super XiaoAI 2.0 features. Some assistant capabilities require particular software versions, compatible devices or later updates. The Inspiration Ball feature is scheduled for a later OTA release and must be enabled in settings, so it should not be treated as available out of the box.
