The back cover of Xiaomiβs smartphone is not just a decorative element, but a complex design that protects the internal components from dust, moisture and mechanical damage. However, sooner or later, owners have to remove it: to replace the battery, repair plumes, clean up dust or install additional modules. Unlike the old βclamshellsβ, modern models of Redmi, POCO or Mi have adhesive joints, hidden latches and fragile elements that are easily damaged if unguarded.
This article will help you understand how to remove the back cover of a Xiaomi phone without the risk of breaking the device. We will look at the design features of different series (from the budget Redmi Note to the flagship Xiaomi 14), list the necessary tools and give step-by-step recommendations taking into account typical errors. Importantly, the procedure requires patience and accuracy - 80% of breakages in self-repair are due to haste.
If you've never taken a smartphone apart before, we suggest you first read the video instructions for your model or contact a service center, but if you decide to do it yourself, follow our advice to avoid common problems, from broken latches to damaged displays.
What tools will be needed to remove the cover
Without the right tools, itβs almost impossible to remove Xiaomiβs back panel β you risk scratching the body, breaking plastic fixtures, or damaging plumes.
- π§ Plastic blade or mediator to gently lick the lid. Metal tools leave scratches!
- π₯ Dryer or thermo-air station - to soften the glue (temperature 60-80)Β°C) Even a household hair dryer at minimum power will do.
- π§² Suction cups (1-2 pcs) - help lift the lid after heating.
- π Thin screwdriver (T3βT5) β for unscrewing screws (if any) in some models POCO screws hidden under stickers.
- π§΄ Isopropyl alcohol (90%+) β acetone or solvents should not be used!
- π οΈ Tweezers and antistatic bracelet β for working with small details and protection from static electricity.
Models with moisture protection (such as the Xiaomi 13 Pro or Redmi Note 12 Pro+) may require a special sealant to be reassembled. Conventional superglue will not work β it will damage the sealing gums.
β οΈ Note: If your model has contactless charging (Qi), there may be an additional metal plate under the lid. It can not be bent or scratched - this will disrupt the wireless charging.
Preparing the phone for disassembly: what to do in advance
Before you start dismantling, follow a few mandatory steps:
- Turn off the phone and remove it. SIM-Even when it's off, the residual charge can cause a short circuit when it comes into contact with tools.
- Remove the cover and film (if any) which can interfere with heating the lid and access to the latches.
- Discharge the battery to 20-30%, and a fully charged battery can ignite if damaged.
- Back up the data. In rare cases, when disassembling, the hardware protection may go off and the memory may be reset.
Also prepare the workplace:
- πͺ Work at a table with good lighting.
- π§Ή Remove small items β cogs are easily lost.
- π± Put soft cloth (such as microfiber) under your phone to avoid scratching the screen.
β οΈ Warning: If your Xiaomi has been in water or been hit hard, disassembly can be dangerous! corrosion or damaged components inside the case can cause short circuits when in contact with air.
βοΈ Preparation for lid removal
Step-by-step: how to remove the back cover Xiaomi
The process of dismantling depends on the model, but the general scheme looks like this:
Step 1: Heating the lid
The glue that glues the back panel becomes elastic when heated. Use a hair dryer:
- π₯ Heat the lid around the perimeter for 2-3 minutes, holding the hair dryer at a distance of 5-7 cm.
- π Pay special attention to the corners - there is usually more glue.
- βοΈ Don't overheat! Temperatures above 80Β°C can damage the battery or display.
Step 2: Filting the lid
After heating:
- With a suction cup, gently lift the lid from one of the corners (usually start from the bottom, where the charging connector).
- Insert a plastic blade into the resulting gap and slowly lead along the edge, separating the glue.
- π« If the lid doesn't respond, heat it up again.
Step 3: Disconnect the latches
Most Xiaomi models have not only glue but plastic latches on their lids, which need to be gently snapped off with a blade as you move around the perimeter, and work especially carefully near volume and power buttons, often with fragile plumes.
Step 4: Complete removal of the lid
When all the latches are disconnected, remove the lid and put it aside. Underneath it, you'll see:
- π Battery (usually glued).
- πΆ Antenna contacts (do not touch them with metal objects!).
- π Camera plumes and buttons (can be taped).
Critically, on Xiaomi 12T, Redmi Note 11 Pro+ and newer models, there may be an additional metal frame screwed under the lid. Don't try to tear it off - unscrew all the screws first!
What to do if the lid is not removed?
Features of removing the lid on popular Xiaomi models
The design of the rear panel varies depending on the series and year of release, and the table below shows the key differences for popular models:
| Model | Type of attachment | Difficulty | Features |
|---|---|---|---|
| Redmi Note 10/11/12 | Glue + 4-6 latch | Medium | The screws are hidden under the stickers at the charging socket, and the lid is fragile, and it breaks easily when pressed hard. |
| POCO X3/X4/X5 | Glue + metal latches | Tall. | Additional metal frame under the lid, requires a T4 screwdriver. |
| Xiaomi 12/13/14 | Glue + 8+ latch | Very high. | Thin glass cover, prone to cracks, it is recommended to use suction cups with a vacuum pump. |
| Redmi 9/10 | Glue + plastic latches | Low. | Simple design, but the battery is glued very strongly - you may need a thread to remove. |
| Xiaomi Mi 11 Ultra | Glue + sealant | Expert | Additional ceramic panel: Requires a special glue for reverse assembly (e.g. B-7000). |
For models with IP53/IP68 protection (for example, Xiaomi 13 Pro or Redmi Note 12 Pro+), after disassembling, be sure to replace the sealing rubber.

If you remove the battery cover, pre-check its voltage with a multimeter. Normal value is 3.7-4.2 V. If the voltage is below 3.5 V, the battery can be bloated (dangerous!).
Common Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi.
- π₯ Overheating with a hairdryer β Plastic latches melt or battery damage Solution: Use a thermometer to control temperature (maximum 80)Β°C).
- πͺ Use of metal tools β Scratches on the case or short circuit Solution: Plastic or wooden blades only.
- π Damage to battery plume β The phone doesn't turn on after assembly. Solution: Disconnect the battery plume first thing after the lid is removed.
- π§ Engagement of alcohol on screen β Oleophobic coating damage Solution: Apply alcohol only on the glue around the edges, avoiding the center.
- π§² Loss of screws β It's impossible to put the phone back together.Solution: Use a magnetic mat or container for parts.
Another common problem is the squeaking or backlash of the lid after assembly, which happens if:
- Not all the latches are fixed (check the corners!).
- The adhesive is applied unevenly (use 3M double-sided tape for even fixation).
- The sealing gum is damaged (replacement is required).
β οΈ Attention: On models with AMOLED-screens (e.g. Xiaomi 12 or Xiao) POCO F4) If you don't take the lid off, you can damage the optical glue that holds the display together with the sensor, and that will create a web on the screen.

If you're taking the lid off for the first time, take a picture of each step of the disassembly, which will help you put the phone back together properly and keep the details in mind.
How to glue the back cover back: assembly tips
Building a phone after repair is as important as disassembling it.
- Clean the surfaces of the old glue with isopropyl alcohol. The residue of the glue can cause the lid to unevenly fit.
- Check the latches, they have to be intact and properly positioned, and you can replace the broken latches with the same ones from the donor phones.
- Apply new glue: For budget models (Redmi 9/10), double-sided 3M 9448A tape will do. For flagships (Xiaomi 13/14), use liquid adhesive B-7000 or LOCTITE 406.
Press the lid evenly
- Put the phone under a press (for example, a heavy book) for 10-15 minutes.
- Do not turn on the phone right away β let the glue dry (at least 1 hour).
Important: After assembly, check:
- πΆ The operation of the antennas (whether there is a signal drop).
- π Charging the battery (does not warm the connector).
- π΅ The work of speakers and microphones (are there wheezing).
When is the best time to contact the service center
Not all breakdowns can be repaired by yourself.
- π₯ The cover cracked during dismantling - special equipment is required to replace the glass (UV-glue-lamp).
- π₯ The battery is swelling, it's dangerous, and you can't puncture it or heat it.
- π± The display stopped working after disassembly - perhaps damaged plume or connector.
- π§ The phone has been in the water - corrosion may not be visible to the naked eye, but it will damage the board in a few days.
- π§ Replacement of chips (such as a power controller) β this requires a soldering station and experience.
