How to open the Xiaomi wireless mouse: detailed instructions with nuances

Xiaomi's wireless mice are stylish and functional devices that are popular for their ergonomic design, long battery life and affordable price. But sooner or later, owners are faced with the question of how to open the case to replace the battery, clean the contacts or fix a malfunction? Unlike wired counterparts, wireless models often have hidden latches or non-obvious mounting mechanisms, which makes the disassembly process a non-trivial task.

In this article, we will discuss how to safely open a Xiaomi wireless mouse (including Mi Wireless Mouse, Mi Bunny, Redmi Wireless Mouse, and others) without damaging the case or internal components. You will learn about hidden locks, necessary tools and typical errors that lead to breakdowns. And if your mouse stops working after falling or getting moisture, here you will find tips for diagnosis and recovery.

Which Xiaomi models support disassembly?

Not all Xiaomi wireless mice are designed to be self-serviced, for example, cast models (such as the Mi Wireless Mouse Lite) are almost impossible to disassemble without damage — their body is glued or soldered. At the same time, most mid- and premium devices (such as the Mi Wireless Mouse 2, Mi Bunny or Redmi Wireless Mouse Silent Edition) have removable covers or screws under rubber legs.

Here is a list of popular models that can be opened without specialized equipment:

• 🖱️ Mi Wireless Mouse 2 – classic model with a magnetic battery cover.
• 🐰 Mi Bunny Wireless Mouse - Ergonomic Mouse with Hidden Latches.
• 🔇 Redmi Wireless Mouse Silent Edition – a silent model with a screw mount.
• 🎮 Mi Gaming Mouse (wireless version) – requires care when removing the top panel.

If your model is not on this list, check for screws under stickers or rubber inserts. Often the manufacturer hides the mounts under a logo or label with a serial number.

Preparing for Discovery: Tools and Precautions

Before you start disassembling, prepare the workplace and the tools you need. Never try to open the mouse with your bare hands, which is almost guaranteed to damage the latches or scratch the body.

• 🔧 Plastic mediator or opener - for careful putting of the cover.
• ⚙️ Screwdriver cross (PH0 or PH1) — leg-screw.
• 🧲 Magnetic screwdriver or tweezers - so as not to lose small screws.
• 📸 Smartphone for photography – fix the location of parts before disassembling.
• 🧴 Alcohol wipes – for cleaning contacts and internal surfaces.

Also consider the following nuances:

⚠️ Note: If your mouse is warranty, disassembly of the case automatically cancels it. In case of factory defects, it is better to contact the Xiaomi service center.

Before starting work, turn off the mouse (if you have a power button) and remove the battery (if possible without disassembling), which will prevent short circuits from accidentally contacting the board. If the mouse does not respond to presses, try to reset it to factory settings - this sometimes solves the problem without disassembling (reset instructions are at the end of the article).

Step-by-step: how to open a wireless mouse Xiaomi

The process of disassembly depends on the model, but the general scheme looks like this:

Inspection of the hull for screws

Turn the mouse over and look at the bottom of the mouse, and the screws may be hiding under:

• 🏷️ Stickers (with Xiaomi logo or barcode).
• 🟢 Rubber legs - they can be gently tucked with a nail or mediator.
• 🖼️ Decorative panels (for example, Mi Bunny screws are hidden under the ears").

If there are no screws, the body is held on the latches, in which case proceed to the next step.

Removal of the top cover (for models without screws)

For mice with a magnetic or snap-cover (e.g., Mi Wireless Mouse 2):

1. Take a plastic mediator and insert it into the gap between the top and bottom of the body on the side opposite the scroll wheel.
2. Carefully lead the mediator along the seam, alternately snapping the fixtures (you will hear characteristic clicks).
3. Don’t put too much effort into it – if the lid doesn’t lend itself, check if you missed the hidden screw.

For models with screws (for example, Redmi Silent Edition):

1. Unscrew all the screws and fold them in a separate place (they may differ in length!).
2. After removing the screws, the lid is usually easily separated, but sometimes it is necessary to tamper with a mediator.

3. Extraction of internal components

After removing the cover, you will see:

• 🔋 Battery compartment (usually) AAA battery-power).
• 📶 Radio module board (2.4 GHz or Bluetooth).
• 🖱️ Scrolling wheel mechanism and buttons.

To get to the fare:

1. Carefully disconnect the scroll wheel plume (if any).
2. Unplug or disconnect the contacts of the battery (if soldered).
3. Unscrew the screws that fix the board (usually 2-4 pieces).

⚠️ Warning: Do not touch the board contacts with your bare hands - static electricity can damage the radio module. Use an antistatic bracelet or periodically touch an earthed object.

Typical Problems and How to Avoid Them

Disassembly of the wireless mouse Xiaomi can turn into trouble, if you do not consider a few key points:

Pay special attention to models with built-in battery (for example, Mi Wireless Mouse 2).If after disassembling the mouse stopped charging, check:

• 🔌 Integrity of contacts on board and battery.
• 🔋 Battery voltage (should be) ~3.7–4.2).
• 🔧 The density of the charging socket plume.

💡

If the mouse doesn't work after assembly, check the polarity of the battery -- sometimes the contacts oxidize. Clean them with an alcohol napkin or a wipe.

Cleaning and repair of internal components

Once you've successfully opened a mouse, you can start servicing it.

1. Contact and fee cleaning

Dust, dirt and oxidation are the main causes of unstable wireless devices.

• 🧹 Use a soft brush or compressed air to remove dust.
• 🧴 Wipe the contacts with an alcohol solution (at least 70%).
• 🔍 Check soldering joints on the board - if they cracked, a soldering iron will be required.

Replacement of battery or battery

If the mouse is discharged quickly:

• 🔋 For models with AAA-Replace the battery with a new battery (Duracell or Energizer is recommended).
• 🔌 For models with built-in batteries, check the capacity with a tester. If it is below 80% of the nominal, the battery should be replaced (look for a similar size and voltage).

3. Repair of buttons and scroll wheels

If the buttons are crashing or the scroll wheel is creaking:

• 🛠️ Lubricate the mechanism with silicone lubrication (do not use it) WD-40!).
• 🔧 Check the springs under the buttons – they may jump or deform.
• 📏 Adjust the gaps between the buttons and the case (sometimes it is enough to bend the metal contacts).

⚠️ Warning: If a mouse becomes a double click response to a single press after cleaning, the problem may be microswitches (omron switches) that require soldering skills to replace.

Assembly of the mouse after disassembly

Collecting a mouse back is often harder than disassembling.

1. Check the location of all the details from the photos taken earlier.
2. Make sure the plumes are tightly connected - they should not hang around.
3. Twirl the screws cross-cross to avoid skewing the body.
4. Check the operation of all buttons before final assembly.

If the mouse is not turned on after assembly:

• 🔋 Check the polarity of the battery.
• 📶 Make sure the radio module antenna is not damaged (thin wiring on the board).
• 🔧 Check the connection of all the plumes.

💡

If the mouse doesn't work after assembly, take it apart again and check the contacts with a multimeter, and most often the problem is a poor battery or antenna connection.
