Xiaomi has introduced the Wireless Mouse 4 Pro in China. The new wireless mouse is priced at 199 yuan (around $29) and is scheduled to go on sale on July 7th.

Xiaomi Wireless Mouse 4 Pro Specifications
The mouse is relatively small, measuring 115.5 by 62 by 36.5 mm, and weighs 66 grams without a battery installed. The dimensions are best suited for users with small to medium-sized hands. It comes in black and white plastic with a magnetic top cover that pulls off to reveal the battery compartment and a storage slot for the included 2.4GHz USB receiver. The bottom of the mouse is fitted with standard PTFE feet.
For the main left and right clicks, Xiaomi is using TTC silent switches. These are built with a longer key travel to provide distinct physical feedback while keeping the actual clicking noise quiet, which is practical for shared office spaces or libraries. The side buttons have a metallic coating and can be remapped, while a small LED indicator on top shows battery life and DPI settings.
For the scroll wheel, Xiaomi uses a dynamic electromagnetic mechanism that changes how it scrolls based on how fast you move your finger. If you scroll slowly, the wheel stays in a stepped, notched mode for standard line-by-line reading. If you flick it faster, the mechanism automatically releases into a free-spin mode to quickly scroll to the bottom of a long document or webpage.

Inside, the mouse uses Xiaomi’s TOG (Track-On-Glass) sensor. It is built to track on clear glass surfaces as long as they are at least 4mm thick, meaning you don’t necessarily need a mouse pad if you work on a glass desk.
For connectivity, the mouse supports up to three devices at once: one through the 2.4GHz USB receiver and two via Bluetooth 5.0. There is a dedicated button on the mouse to cycle through the connected computers or tablets.
The mouse supports a web-based driver. You can navigate to a browser utility to adjust the DPI (which has hardware presets of 1000, 1600, and 2400), remap the side buttons, and change performance settings without installing extra software on your machine.
In related news, Xiaomi has recently launched the Mijia Handheld Fan in a fresh new green color, alongside a new 5L smart kettle with app control, 1°C temperature adjustment, and water circulation technology.
