Xiaomi Mi wireless mice (Mi Mouse, Mi Portable Mouse, Mi Silent Mouse, etc.) are popular for their compactness, ergonomics, and long battery life. However, over time, even the most reliable technology requires maintenance: dust cleaning, replacing the battery, repairing buttons or wheels. To disassemble the Xiaomi mouse is not as easy as it seems - the manufacturer uses hidden latches and glue to prevent accidental opening.
In this article, you will find step-by-step instructions for all current models (including the Mi Mouse A1, Mi Lite, Mi Pro and Mi Silent Edition), a list of tools you need, and tips for safely opening without damaging the body. We will also tell you how to avoid typical errors that lead to mount failure or loss of warranty. If your mouse stops working, jammed the wheel or just needs to be cleaned, this guide will help you do everything yourself.
What models of Xiaomi Mi mice can be disassembled at home
Not all Xiaomi mice are equally easy to disassemble, the manufacturer uses different types of mounts depending on the model and year of release. Below is a table with the devices and their features that are relevant for 2026:
| Model | Type of attachment | Difficulty disassembling (1-5) | Frequent reasons for disassembly |
|---|---|---|---|
| Mi Mouse A1 (2020) | Latches + glue | 3 | Cleaning the wheel, replacing the battery |
| Mi Portable Mouse Lite | Just the latches. | 2 | Repair buttons, remove dust |
| Mi Silent Mouse | Latches + screws under the legs | 4 | Replacement of micro-switches, cleaning of the sensor |
| Mi Mouse Pro (2023) | Screws + glue + latches | 5 | Update of firmware, battery replacement |
| Mi Dual Mode Wireless Mouse | Latches + magnetic latches | 3 | Cleaning the optical sensor |
The Mi Mouse Pro and Mi Silent Mouse are considered the most difficult models to disassemble because of the combined mounts. If your mouse is not on this list, check its exact model on the sticker under the case or in the documentation. Metal-bodyed mice (such as the Mi Metal Mouse) are different, they will need a special tool to remove the top cover.
Preparation for disassembly: tools and precautions
Before you start opening the case, prepare everything you need, and the lack of the right tools is the main cause of damage to plastic latches or scratches on the case.
- ๐ง Plastic mediators or shoulder blades (2-3 (S) to remove the stainless stains.
- ๐ฉ Screwdriver T5 or T6 (depending on model) for screws under legs.
- ๐งฒ Magnetic substrate or bowl โ so as not to lose small details.
- ๐ธ Smartphone for photography โ fix the location of parts before disassembling.
- ๐งด Isopropyl alcohol (70%+) โ Cleaning contacts and fees.
- ๐งน Soft brush or compressed air cylinder to remove dust.
Important: If your mouse is warranty, disassembly will void it. Check the conditions at Xiaomi service center before you start work. Also pay attention to the hidden screws under the stickers or legs - they are often overlooked, which leads to break the latches when you try to separate the case.
โ ๏ธ Warning: Don't use metal screwdrivers or knives to unplug the latches! The plastic of the Xiaomi Mi body is thin and easily breakable. If the latches don't lend themselves, check if all screws are twisted.

Step-by-step: how to disassemble the Xiaomi Mi mouse (universal method)
This guide is suitable for most models, including the Mi Mouse A1, Mi Lite and Mi Dual Mode. There are some nuances for the Mi Silent Mouse and Mi Pro, which are described in the next section.
Step 1: Removal of legs and stickers
Turn the mouse over and carefully remove the rubber legs (you can put them in a plastic spatula) and there are often screws underneath them, and check the serial number sticker, which sometimes has another screw hidden underneath (for example, in the Mi Mouse A1).
Step 2. Screwing the screws
Use a T5 or T6 screwdriver (depending on the model) to remove all visible screws. Some mice (e.g., Mi Portable Mouse Lite) don't have screws - the body is only held on the latches.
Step 3: Separation of the hull
Insert a plastic blade into the gap between the top and bottom of the body (start with the side without buttons). Carefully drive the blade along the seam, alternately snapping the locks. Don't force - if the body does not detach, then you missed the screw or latch.
Step 4: Extracting the fee
Once you remove the top cover, you'll see a circuit board attached to 1-2 screws, unscrew them and carefully pull the board, do not pull the wires (in wireless models, they can be soldered to the battery compartment).
What to do if the latch breaks?
Features of disassembly Xiaomi Mi Silent Mouse and Mi Pro
These models have additional elements of disassembly protection, so they require a special approach.
For Mi Silent Mouse:
- Remove the upper cover of the wheel (it is attached to two latches and removed by moving up).
- Under the cover you will find 2 T5 screws - unscrew them.
- The body is held on 4 latches on the sides and 2 magnetic latches on the front. Use two blades at the same time to evenly separate the parts.
For Mi Mouse Pro:
- Remove 4 screws under the legs (2 of them can be hidden under stickers).
- Heat the body with a hair dryer (temperature 50-60 ยฐ C) for 1-2 minutes - this will soften the glue.
- Disconnect the body from the back (where the battery is located). Be careful - the board is attached to the top cover with thin wires.
โ ๏ธ Warning: The Mi Mouse Pro uses a lithium battery soldered to the board. Do not attempt to disconnect it without a temperature-adjusted soldering iron (maximum 300ยฐC).
๐ก
If the mouse wheel becomes less responsive after disassembling, lubricate it with silicone lubrication (e.g. WD-40 Specialist Silicone). Don't use hydrocarbon-based oils - they break down plastic.
Cleaning and repair of internal components
After disassembly, you can start maintenance.
- ๐ Button microswitches: If the buttons fail or fail, they must be replaced (details can be found on AliExpress for "Xiaomi Mi mouse switch").
For deep cleaning of the board, use an ultrasonic bath with isopropyl alcohol (no more than 5 minutes at 40ยฐC). After cleaning, dry the board with a hairdryer for 10-15 minutes. Do not turn on the mouse until all parts are completely dry!
If the mouse does not turn on after assembly, check:
- Correct connection of the plumes (in Mi Pro, the touchpad plume often departs).
- Polarity of the battery (in models with replaceable batteries).
- Integrity of the fuse on the board (it can burn out with a short circuit).
Xiaomi Mi mouse assembly: how to avoid mistakes
Assembling is often more difficult than disassembling. Follow these rules so you don't have to start over.
- Check the location of all the latches before closing the case, and if one doesn't fit, the case will hang around.
- Don't pull the screws over, because it can cause cracks in the plastic, and pull them into the cross (like a car wheel).
- Make sure all the plumes are connected (there are three in the Mi Pro: touchpad, sensor, wheel).
- Check the buttons before final assembly โ connect the mouse over the wire (if the model supports) or temporarily insert the battery.
After assembly, test the mouse in Paint or a special utility (such as X-Mouse Button Control):
- Check the smoothness of the cursor.
- Make sure all buttons are triggered without delay.
- Scroll the wheel in both directions - there should be no extraneous sounds.
โ ๏ธ Warning: If, after assembly, a mouse double-clicks files instead of a single mouse, the left-hand button switch is incorrectly installed or contaminated. Disassemble the mouse again and clear the contacts.

The most common mistake in assembly is a skewed board. If the case does not close smoothly, check if the wire or dust is under the board.
Frequent breakages of Xiaomi Mi mice and how to fix them
Many problems can be solved without disassembly, and here are the typical malfunctions and ways to fix them:
| Problem. | Possible cause | Decision |
