Xiaomi 18 Fold (CN Version)

Important Notice: This is a Chinese-market Xiaomi model. The system supports English and Chinese languages only. The Google Play Store can be installed, but it is not pre-installed on the device. Please consider these software and language differences before purchasing.

A compact outer screen opens into a wide 7.58-inch workspace on this Chinese-market foldable smartphone. The XRING O3 processor, Leica triple cameras and 6000mAh typical battery bring substantial hardware into a 219g design. PDAPlaza offers this CN Version with the memory and color combinations shown in the selectors; its Chinese-market software and regional services require particular attention before purchase.

Key features

5.38-inch outer and 7.58-inch inner AMOLED displays, with adaptive refresh up to 120Hz.
XRING O3 with a 10-core CPU, 16-core GPU and dedicated four-core NPU.
Leica 200MP main camera, 50MP periscope telephoto and 50MP ultrawide.
6000mAh typical battery with 67W wired and 50W wireless charging using compatible equipment.
Up to 16GB LPDDR6 RAM and 1TB UFS 4.1 storage on the top configuration.
Dual-layer UTG folding construction with IP58/IP59 laboratory-rated protection.

A compact phone that opens into a wider screen

The 5.38-inch outer display handles quick interactions without unfolding the phone. Open it for a 7.58-inch inner screen suited to reading, viewing content and working across compatible apps. Both displays support adaptive refresh up to 120Hz, HDR formats and DC dimming across the brightness range; the refresh rate changes with the application.

The body measures 5.02mm unfolded and 10.68mm folded, excluding the camera bump. Warm Gold White, Black and Xiye Red use a glass back, while the pink Ceramic Special Edition uses silicon nitride ceramic. The inner screen’s factory protector should remain in place and be replaced through manufacturer service rather than removed or covered with another film at home.

XRING O3 and configuration-specific memory

The 3nm XRING O3 combines a 10-core CPU running at up to 4.35GHz with a 16-core G2-Ultra NX GPU and a four-core NPU. Xiaomi HyperOS 4 supports multitasking with up to six compatible apps in split-screen layouts. The 16GB/1TB version uses LPDDR6 RAM; the other listed configurations use LPDDR5X, with UFS 4.1 storage throughout.

Leica cameras from ultrawide to telephoto

A 200MP main camera with optical stabilization sits alongside a 50MP ultrawide and a stabilized 50MP periscope telephoto. The telephoto provides 3.5× optical zoom; the separately described 7× mode is optical-quality zoom. Rear recording reaches 8K at 24fps, with 4K at 60fps also available, including Dolby Vision across focal lengths.

Leica image styles, Pro mode, motion capture and portrait tools offer different ways to shape the result. Two 16MP front cameras support selfies and video calls on the inner and outer displays. Audio-source tracking is available for video when enabled in the camera settings.

Charging equipment and everyday protection

The non-removable battery has a typical capacity of 6000mAh and a minimum rated capacity of 5875mAh. Reaching the supported 67W wired charging mode requires a compatible Xiaomi kit rated at 67W or more. The 50W wireless mode requires Xiaomi’s 80W lifting air-cooled wireless stand and a Xiaomi 90W-or-higher charging kit, which are separate accessories.

IP58 and IP59 ratings describe controlled laboratory tests, not unrestricted underwater use. Protection can decline with wear, a wet phone must not be charged, and liquid-immersion damage is excluded from the manufacturer’s warranty. The supplied USB-C cable also has a separate limitation: USB 3 data speeds require a different, separately purchased cable.

Configurations and regional details

The Storage selector uses 12GB/256GB, 12GB/512GB, 16GB/512GB and 16GB/1TB; the first capacity is physical RAM and the second is internal storage. Warm Gold White, Black and Xiye Red are offered in each pair. Ceramic Special Edition (Pink) is paired only with 16GB/1TB and is currently out of stock. PDAPlaza presents these as native choices on one product page so that the selected memory and finish identify the exact configuration.

This Chinese-market edition includes Xiaomi HyperOS 4 and Super XiaoAI 2.0. NFC payments, transit services, digital car keys, HD voice and dual-active SIM features depend on the applicable region, provider, vehicle or software. The published cellular bands are listed below; matching a band alone does not establish every carrier feature or universal network compatibility.
