Why Removing Xiaomiβs Cover Needs Caution
Xiaomiβs back cover is not just a decorative element, but a sophisticated engineering design that protects the interior components from dust, moisture and mechanical damage. 9T) The manufacturer uses a combination of adhesives and plastic latches, which makes it difficult to disassemble, and the wrong actions can lead to cracks in the glass panels, damage to the plumes or even loss of leakage. IP-Certification (if any).
The main reasons why users decide to remove the cover:
- π Replacement of the battery (especially important for models older than 2 years)
- π± Repair or replacement of the display/touch screen
- π§ Cleaning from dust or recovery after liquid ingestion
- π οΈ Modding (installation of additional modules, for example, wireless charging)
Itβs important to understand that even if you successfully remove the lid, reverse assembly can be even more difficult, as the glue loses its properties after the first opening, and new latches often break when re-installed. In this article, weβll look at all the current techniques for different generations of Xiaomi smartphones, including the budget Redmi and flagship Mi/Mix series.
Preparation: security tools and measures
Before you start disassembling, make sure you have everything you need, and even one tool that you don't have can damage the body or the internal components, and here's the minimum set you'll need:
- π§ Plastic blades/mediators (2-3 pc, thickness 0.2β0.5 mm)
- π₯ Hair dryer or thermo-air station (for softening glue, temperature 60-80)Β°C)
- π§² Magnetic screwdriver (cross, size) PH00 or PH0)
- π Suction cups (for models with glass back panel, for example, Mi 11)
- π§΄ Isopropyl alcohol 90%+ (glue-cleaner)
- π New glue tape (e.g., scotch, 3M 9448A electronics)

Note: If your Xiaomi smartphone has an official warranty, removing the lid will cancel it. The manufacturer uses special seals (for example, on screws under the lid) that break down when you open. Check the warranty status in the Mi Service app before starting work.
Also note that some models (such as the Poco F3 or Redmi K40) have hidden latches under decorative inserts. If you are not sure about the location of the mounts, it is better to pre-examine the disassembly maps for your model.
Method 1: Removal of the cover by heating (for adhesive models)
This method is suitable for most modern Xiaomi smartphones, where the back cover is glued around the perimeter. IP-The main objective is to heat the glue evenly to a temperature at which it becomes elastic, but does not melt.
Step-by-step:
- Turn off your smartphone and remove it. SIM-Memory card (if there is a slot).
- Heat the back panel with a hair dryer for 2-3 minutes, keeping it at a distance of 5-7 cm. The temperature is 60-70 Β° C (not higher!). Pay special attention to the corners and edges.
- Hold the suction cup closer to one of the corners (like the bottom left). Pull it up carefully, and if the lid doesn't lend itself, warm it up for another 30 seconds.
- Put a plastic blade in the gap, run it along the edge, gradually detaching the lid, and if you feel resistance, stop and warm up the place.
- Repeat the process for all sides. Don't try to pull the lid off abruptly, it'll lead to cracks!

Note: On models with glass back panels (such as the Mi 10T or Redmi K30 Pro), don't use metal tools - they can scratch the surface. Also avoid overheating: if the glass gets too hot, it can crack when cooled.

Method 2: Disassembly of models with latches (Redmi 4X, Mi A1, etc.)
Older Xiaomi models (until 2018) often had plastic caps with latches around the perimeter, which require less effort, but more accuracy - plastic becomes brittle over time. Typical representatives: Redmi 4X, Mi A1, Redmi 3S.
Algorithm of action:
- π§ Start at the bottom edge of the lid (where the charging connector is). Insert a plastic blade and gently press upwards.
- π You'll hear the characteristic clicks -- these are the mounts that are snapping. Don't put too much effort into it!
- π± After separation of the lower part, swipe along the side faces, gradually freeing all latches.
- π« Don't pull the lid around corners, it can break the mounts.
β οΈ
Note: Some models (e.g. Redmi Note 4X) have a plume of antenna attached to the inside of the lid, so if you tear the lid abruptly, you can pull it off the board, and before you take it off, make sure that something is preventing you from completely separating the panel.
For clarity, the following table with the features of disassembling popular models:
| Model | Type of lid attachment | Features | Difficulty (1-5) |
|---|---|---|---|
| Redmi Note 8/8T | Glue + latches | Glass panel, high risk of cracking | 4 |
| Poco X3 NFC | Perimeter glue | A thick layer of glue, requires strong heating | 3 |
| Mi 9 Lite | Glue + hidden latches | Thin aluminum frame, easy to bend | 5 |
| Redmi 7A | Latches (no glue) | Plastic is fragile, the latches break when reassembled | 2 |
Method 3: Removal of the lid on flagships (Mi 11, Mix 4, etc.)
Xiaomiβs flagship models (such as the Mi 11 Ultra or Mix Fold) have the most complex design.
- π Double-sided glue of increased strength (often with reinforcing fibers)
- π‘οΈ Additional mounts near the camera or connectors
- π Sealed sealants for protection from moisture (IP53 higher)
For such devices, it is necessary to use:
- π₯ Thermo-air station with temperature control (up to 90)Β°C)
- π§² Special vacuum-mounted suction cups
- π Set of blades of different thicknesses (including ultra-thin for plumes)
β οΈ
Attention: The Mi Mix 4 and similar models have fragile flexible plumes under the lid of the underscreen camera and sensors, and if they are damaged, your front camera or fingerprint scanner will not work, and if you don't have experience with this technique, you should contact the service.

What to do after removing the lid: tips for assembly
If you take the back panel off successfully, you'll see the interior design of the smartphone, but the reverse build is just as important.
- π§Ή Clean the glue residues with isopropyl alcohol. Don't use acetone or solvents, they'll damage the plastic!
- π If you're replacing the battery, check the contacts on the board.Oxidation can lead to poor contact.
- π§ To re-install the cover, use a new adhesive tape (e.g. Tesa 61395). Apply it with continuous tape around the perimeter.
- π₯ When heated, it is enough to glue 50-60Β°C β This will prevent plastic deformation.
β οΈ
Note: If your smartphone has IP-Certification (e.g. Redmi Note 10 Pro with a IP53), After disassembling it, it will be lost, and it will require professional equipment and original seals to restore the leakage.
To check the performance after assembly:
- Turn on your smartphone and check the sensor, camera, speakers.
- Connect charging β make sure there is no overheating at the contact area.
- Call the device β check the microphone and network modules.

If the lid is not tightly attached or βplaysβ after assembly, the cause may be an uneven distribution of glue. To correct this, carefully warm the problem area with a hairdryer (not higher than 60 Β° C) and press the lid for 10-15 minutes under the load (for example, a book).
Disassembly maps for popular Xiaomi models
To make the process easier, we have prepared latches and adhesive layouts for the most common devices, and note that the design may vary slightly depending on the regional version (e.g. Redmi Note 9 Pro for India vs. global version).
Examples:
- Redmi Note 8 Pro: 12 latches around the perimeter + glue at the bottom (near the Type-C connector).
- Poco X3 Pro: The glue around the perimeter, but the densest layer at the top (near the camera).
- Mi 10 Lite: Hidden screws under decorative legs (required to remove them before the lid is removed).
π To accurately determine the design of your model, we recommend using services such as iFixit or Xiaomi Service Tool, where there is a 3D-Disassembly schemes with marks on fragile elements.

Before disassembling, always check for hidden screws or plugs β skipping them can damage the board when trying to separate the lid.
Frequent Mistakes and How to Avoid Them
Even experienced users sometimes make mistakes that lead to breakdown.-5 Problems and ways to prevent them:
- Cracks on the glass cover Cause: Uneven heating or use of metal tools Solution: Use silicone suction cups and heat the lid gradually, starting at the edges.
- Battery plume damage Cause: Sharply detach the lid without checking for glued elements Solution: Before removing the lid completely, make sure nothing reaches behind it (plates, antennas).
- Loss of power/volume buttons Cause: The buttons are attached to thin plastic holders that break when untidy.Solution: Once the lid is separated, remove the buttons immediately and put them aside.
If you've already made a mistake, don't panic, for example, a crack in a glass panel can be temporarily sealed with transparent tape, and a torn plume can sometimes be soldered back (but this requires professional skills).
