Removing the back cover of a Xiaomi smartphone is a necessary step to replace the battery, repair the camera or clean the internal components. However, the wrong actions can lead to cracks in the case, damage to the plumes or loss of leakage. In this article, we will understand how to open the rear panel on different models Xiaomi, Redmi and POCO, what tools you need and what to look for to avoid turning a simple repair into expensive.
The manufacturer uses different methods of mounting the cover: from classic latches to adhesive joints with sealing according to the standard IP53/IP68. For example, the flagship models of Xiaomi 13/14 or Redmi Note 12 Pro+ They have a more complex design than budget POCO M5 or Redmi 10A. It is also important to consider that the warranty Xiaomi is canceled at self-opening – this point is critical for new devices.
Before you start, evaluate your skills: if you've never taken a smartphone apart, you'd better go to a service center, but if you're confident, follow our instructions with a particular model and its features in mind.
1.Preparation: security tools and measures
To take the back cover of Xiaomi off carefully, you'll need specialized tools, and the use of improvised tools (knives, screwdrivers, plastic cards) often ends in scratches on the body or chipped glass.
- 🔧 Plastic mediator or suction cup to separate the lid from the case without damage, mediators from the smartphone repair kit are thinner than a credit card and do not scratch the surface.
- 🔥 Dryer or thermal air station - for softening the glue (relevant for models with sealing, for example, Xiaomi) 12T Pro or Redmi Note 11 Pro+ 5G).
- 🧲 Screwdriver. T3/T4/T5 — For twisting screws under the lid (if any) in some models, the screws are hidden under stickers.
- 📦 A blade made of metal or plastic, for gently grazing the latches. Importantly, the metal blade should be thin and shallow!
- 🧴 Isopropyl alcohol (90%+) — cleaning up the glue after opening.
Also, prepare the workplace: the desk should be clean, without debris and small parts, it is advisable to use an antistatic mat or at least work on a wooden surface - this will reduce the risk of damage to the motherboard by static electricity.
⚠️ Warning: Do not use a household hair dryer at maximum power! The air temperature should not exceed 80-90°C - if you overheat, you can damage the battery or display. Keep the hair dryer at a distance of 10-15 cm from the body.
2. Determine the type of mounting of the cover on your model
Xiaomi uses three main types of rear panel mounting:
- Latches are the easiest option, common in budget models (Redmi 9A, POCO C31), the lid is held on plastic clips around the perimeter.
- Glue + latches - a combined method (for example, Redmi Note 10 Pro, Xiaomi 11 Lite NE) Here the adhesive is applied point-by-point, and the main retention provides the latches.
- Full slugging - used in water-protected flagships (Xiaomi 13 Ultra, Mix Fold 2) and the lid is glued around the perimeter and requires heating to remove it.
To understand what type of mount your model has, check:
- 🔍 The presence of rubber plugs in the connectors (USB, 3.5 mm) - sign of sealing.
- 📄 Official documentation on the Xiaomi website (Service and Support section").
- 🎥 YouTube Disassembly – Look for videos with your exact model (e.g., “Xiaomi Redmi Note 12 Disassembly").
Critical: If your smartphone is IP68 certified (e.g. Xiaomi 13 Pro), after self-opening, the water protection will be broken!
3. Step-by-step instruction: remove the lid on the latches
This method is suitable for most budget and mid-budget models (Redmi 10, POCO X3 Pro, Xiaomi Mi A3). The main rule is to act slowly and without sudden movements.
Step 1. Turn off your smartphone and remove SIM-This will prevent short circuits from accidentally touching the board.
Step 2: Heat the edges of the body with a hair dryer for 1-2 minutes. Even if the lid is on the latches, light heating will make the plastic more elastic and reduce the risk of breaking the clips.
Step 3: Put the mediator in the gap between the lid and the body. Start at the bottom edge (near the USB-C connector), as there are usually fewer latches. Carefully drive the mediator along the perimeter, alternately snapping clips.

Step 4: Lift the lid after all the latches are snapped. Don't pull it out too hard, because plumes can be glued under the lid (like the fingerprint scanner in Redmi Note 11).
⚠️ Warning: If the lid is not amenable, don't force it! You may have missed the latch or the model has an extra mount. Check the video disassembly for your device.
4. Removal of the glued cover (flagships and models with IP-certification)
Full-cleaning models (Xiaomi 12S Ultra, Mix 4, Redmi K50 Pro) require a more careful approach, where the main thing is to heat the glue evenly and use a suction cup for inicial separation of the lid.
Algorithm of action:
- Heat the back cover with a hair dryer around the perimeter for 3-5 minutes. Move the hair dryer in circular movements so that the glue softens evenly.
- Stick the suction cup to the top of the lid (near the camera) and pull up. If the lid doesn't lend itself, heat it up for another 1-2 minutes.
- Insert a mediator into the gap and slowly move it along the edge, separating the glue. Be prepared to resist, the glue can be very sticky.
- After removing the lid, clean the glue residues from the body and the lid with isopropyl alcohol. Use a new adhesive (e.g., B-7000 or T-7000) to reassemble.
Features for models with aluminum frames (for example, Xiaomi 11T Pro): the metal heats up faster, but also cools down instantly. Work quickly but carefully to prevent the frame from deforming.

5. Common Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi, and here are the most common problems and ways to prevent them:
| Mistake. | Effects of consequences | How to avoid |
|---|---|---|
| Using metal screwdrivers instead of a mediator | Scratches on the body, broken glass | Use only plastic or nylon tools |
| Heating of the housing above 90°C | Melting plastic, battery damage | Control the temperature with a thermometer or keep the hair dryer at a distance |
| Sharp compartment of the cover without checking the plumes | The failure of the fingerprint scanner plume or NFC-antennae | Before the complete removal of the cover, raise it by 1-2 mm and check the presence of plumes. |
| Using superglue to reassemble | Damage to plastic, inability to open the next | Use a specialised adhesive (B-7000, T-7000) or double-sided scotch |
Another common mistake is ignoring the order of shutting down the plumes. For example, in the Xiaomi Mi 11, the battery plume is located under a metal plate, and accidentally grazing it can lead to a short circuit. Always turn off the battery first!
Is there any dust or debris under it?
Are the sleeves properly laid (they should not be overblown).
— Is there enough glue on the edges (add a thin layer if necessary) B-7000).-->
6. Features for popular Xiaomi models
Each Xiaomi series has unique disassembly nuances. Let's take a look at the most common models:
Redmi Note 10/11/12 series series
Xiaomi 12/13/14 series
POCO F/X series
💡
Before disassembling flagship models (Xiaomi 13 Ultra, Mix Fold), be sure to study the layout of the plumes. They often have additional sensors (for example, laser autofocus) that are attached directly to the cover.
7.Assembly: How to properly install the lid back
Successful removal of the lid is only half the battle, and it is equally important to build your smartphone properly to avoid creaking, backlashes, or button problems.
Step 1: Surface cleaning
Remove the residues of old glue from the body and cover with isopropyl alcohol and a lilac-free wipe. Pay special attention to the places around the camera and connectors.
Step 2: Checking the plumes and components
Make sure that:
- 🔌 All plumes connected (fingerprint scanner, NFC, antennae).
- 🔋 The battery is securely secured (if you have removed it).
- 📶 Volume and power buttons are not blocked by the lid.
Step 3: Applying glue (if required)
For models with gluing:
- Apply a thin layer of B-7000 glue around the perimeter of the body (don’t overdo it – excess can get inside!).
- For water protection (IP68) use UV-glue and ultraviolet lamp.
Step 4: Installation of the cover
Line the lid on the connectors and press it gently, starting at the top (near the camera). Use clamps or heavy books to stick evenly (but don't overdo it with pressure!).
⚠️ After assembly, check the operation of all sensors: - Fingerprint scanner. — NFC (Payment and data transfer. — Camera (whether there is a blur due to the shifted module). If something does not work, take the smartphone apart again and check the plumes.
