Xiaomi 18 Pro Max 16GB/512GB Black (China Version) – Snapdragon 8 Elite Extreme Gen 6, 2.9-Inch Rear Display, 8500mAh, 100W, Dual 200MP Leica

The Xiaomi 18 Pro Max 16GB 512GB Black is the 16 GB + 512 GB version of Xiaomi’s largest new phone, finished in black glass fibre. Xiaomi launched the 18 Pro Max in China on 23 September 2026, and this is the China version. It has the Snapdragon 8 Elite Extreme Gen 6, a 6.9-inch AMOLED display with a privacy screen, a 2.9-inch rear display, two 200 MP Leica cameras and an 8500 mAh battery with 100 W wired charging.

Why 16 GB of RAM matters

16 GB of LPDDR5X is the most memory Xiaomi offers on the 18 Pro Max, and this version pairs it with 512 GB of UFS 4.1 storage for CNY 8,999 in China. More memory lets more apps stay open in the background, so switching between a game, a video call, the camera and a messaging app does not reload them. If you record gameplay, edit clips on the phone or simply keep dozens of apps open, the Xiaomi 18 Pro Max 16GB 512GB Black has the headroom of the top model with half its storage and a lower price.

A 6.9-inch screen with a privacy mode

The main display is a 6.9-inch AMOLED at 2624 x 1208 that adapts from 1 to 120 Hz and samples touch at up to 300 Hz. Its hardware privacy mode darkens the picture for people beside you while you still see it clearly, which is handy on the metro. Xiaomi quotes up to 4000 nits multi-scene peak brightness in its lab tests, and the Xiaomi 18 Pro Max 16GB 512GB Black dims down to 1 nit at night.

Black in everyday use

The black finish uses Xiaomi’s glass-fibre back, which keeps the phone at 235 g and 8.39 mm. Its surface shows smudges far less than glass, and black matches any case you add later. For a phone that goes into meetings, the car and the gym every day, the Xiaomi 18 Pro Max 16GB 512GB Black is the colour that still looks new after months.

Before you buy: China version

The Xiaomi 18 Pro Max 16GB 512GB Black comes from Xiaomi’s mainland China range and runs the China edition of Xiaomi HyperOS 4, as Xiaomi has not released a global model yet. Its China spec sheet does not mention Google services; message us if you need them. The band list covers the main UAE networks, including GSM 900/1800, LTE 1 and 3 and 5G n78, and the phone takes two Nano-SIM cards with no eSIM.

Who This Is Not For

At 235 g and 6.9 inches it is a big phone for one-handed use. If you already know you will shoot a lot of 8K video, the 1 TB version gives twice the space with the same 16 GB of RAM. This is the China version: Xiaomi lists no eSIM, its China spec sheet does not list Google services, and it has no local Xiaomi UAE agent warranty.
