Why would you need to open the back cover of Xiaomi Redmi?
The back cover of the Xiaomi Redmi smartphone is not just a decorative element, but a protective barrier for internal components. However, there are situations when it needs to be removed: replacing the battery, cleaning from dust, repairing plumes or even installing additional modules (for example, NFC-The manufacturer does not provide easy access to the "inners" of the device, so the procedure requires caution.
Many users are afraid of damaging the case or display when trying to open, and these fears are not to be considered. Modern Redmi (starting with the Note 8 and Redmi 9 series) often have adhesive cap fixation, and budget models can use latches. Wrong actions lead to plastic cracks, plumes break, or even battery damage. In this article, we will discuss three main methods of opening, suitable for most models, and also explain how to avoid typical errors.
Before you start, consider that self-repair is not warranty if the device is still in warranty service, in which case it is better to contact the Xiaomi service center, if the warranty has expired or not, follow our recommendations.
What tools will you need to remove the lid?
Without the right tools, it's almost impossible to open the Redmi lid. Here's the minimum set you'll need:
- π§ Plastic blade (or mediator) - for careful putting of the lid. Metal objects (knives, screwdrivers) leave scratches!
- π₯ Hair dryer or thermoair station - for softening the glue (needed for models with adhesive fixation, for example, Redmi Note 10 Pro).
- π§² Suction cups help to lift the lid evenly without damaging it.
- π¦ Set of screwdrivers (cross, star) T3, T5) β screw-up.
- π§΄ Isopropyl alcohol (90%+) β Removal of glue residues after opening.
If you have a Redmi model with a non-removable battery (for example, the Redmi 9A or Note 11), additionally prepare plastic separators - they will help to safely disconnect the battery from the motherboard after removing the lid. Do not use metal tools to work with the battery - this is fraught with short circuit!
β οΈ Note: Some Xiaomi Redmi models (e.g. Redmi) K40 or Note 12 Pro+) They have hidden latches under decorative plugs. If the lid does not respond after warming up, check for screws under the stickers or in the compartment. SIM-map.
Method 1: Disassembly of the lid with glue fixation (for most modern models)
This method is suitable for most Redmis released after 2019, including Redmi Note 10, Redmi 11 Prime, Redmi K50 and others.Adhesive fixation complicates the process, but with the right approach, the lid can be removed without damage.
Step 1: Warming up the cover
The glue that glues the back panel becomes elastic when heated to 60-80 Β° C. Use a dryer at minimum power or a thermal air station:
- Direct the flow of hot air to the edges of the cover, holding the hair dryer at a distance of 5-7 cm.
- Warm up around the perimeter for 2-3 minutes, paying special attention to the corners.
- Donβt overheat one place β it can warp plastic or damage the battery.
Step 2: Filting the lid
Once you've warmed up, take a plastic spatula and start gently pulling the lid from any angle. You'd better start from the USB-Type C side of the connector -- there's usually less glue. If the lid doesn't lend itself, warm it up again.
Warm the edges with a hairdryer (60β80Β°C)
Use a plastic spatula (not metal!)
Start at the corner USB-plug
Resistance: Reheat, do not use force.-->
Once you have a gap, insert a plastic separator or a second mediator into it so that the lid doesn't stick back in, and continue to walk gently around the perimeter, gradually increasing the gap.
β οΈ Warning: If black sealing rubber bands are visible under the cover (for example, in protected models) IP53), Don't pull them, they attach to the body and they break easily, and their loss will disrupt the dust protection!
Step 3: Disconnect the plumes (if necessary)
In some models (such as the Redmi Note 11 Pro), the back cover is connected to a fingerprint scanner or antenna plumes. If you feel resistance when you remove the lid, do not pull it by force, first disconnect the plumes, detach them with a plastic blade.
| Xiaomi Redmi Model | Type of cap fixation | Features of the parsing |
|---|---|---|
| Redmi Note 10/10 Pro | Glue + latches | The fingerprint scanner plume is attached to the cover. |
| Redmi 9/9A/9C | Latches | The cover is removed without warming up, but fragile - easily breaks. |
| Redmi K40/K50 | Glue + screws under stickers | First, twist the screws in the compartment of the SIM-card, then warm up. |
| Redmi Note 12 Pro+ | Glue + hidden latches | It requires a suction cup for a uniform rise. |
Method 2: Removal of the lid on the latches (for budget models)
Xiaomi Redmi low-end models (e.g. Redmi 8A, Redmi 9A, Redmi 7) often have a lid on plastic latches. It does not require heating, but requires accuracy - the latches are fragile and easily break.
Algorithm of action:
- Turn off the phone and remove the tray. SIM-map.
- Insert a plastic blade into the gap between the lid and the case from the USB-connector side.
- Carefully drive the blade along the edge until you hear the characteristic clicks of the detachable latches.
- Once all the latches are snapped, remove the lid without making any effort.
If the lid doesn't lend itself, don't push harder -- you've probably missed the latch. Check if there's any hidden mounts under the stickers or in the corners of the case. In Redmi 9C and Redmi 8 models, there are sometimes additional latches of the display -- you have to snap them separately.

If the latch breaks when the lid is removed, it can be replaced with a similar one from the repair kit (sold on AliExpress or in parts stores), the main thing is to find the right size.
Method 3: Disassembly of the lid with screws (for flagships and game models)
Xiaomiβs flagship and gaming models, such as the Redmi K60, Black Shark (based on Redmi), or Redmi Note 12 Turbo, often have screws under decorative plugs.
Instructions:
- Remove all stickers and stubs (usually located from the camera or USB-Type C connector).
- Unscrew the screws with a T3 or T5 screwdriver (depending on the model).
- Warm up the edges with a hair dryer (even if the lid is on the screws, there is often extra glue).
- Put a plastic lid on the lid and remove it as in Method 1.
In some models (for example, Redmi K50 Gaming) screws can be of different lengths - remember their location, so that when you build it, do not confuse. Using the wrong screw can damage the motherboard!

Frequent Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when parsing Xiaomi Redmi, and here are the most common ones and ways to prevent them:
- π₯ Overheating of the lid - leads to deformation of the plastic or detachment of the tinting. Use the hair dryer at minimum power and keep it at a distance.
- π₯ Abrupt removal of the lid - can break the plumes or tear antenna contacts. Always check if there are any mounts inside.
- π§ Using metal tools, scratches the body and leaves burrs, only plastic or special shoulder blades!
- π Working with the battery is a risk of short circuit.
- π§© Loss of small parts -- screws, latches, rubber seals. Work on a clean surface and use a magnetic mat.
One of the most frustrating mistakes is that the flexible plume of the display is damaged, and it passes through the edge of the body, and a sloppy movement of the blade can tear it up, and if the screen doesn't turn on after assembly or artifacts appear, the plume is likely damaged. In this case, a replacement will be required, which will cost 1500-3000. β½ service-centre.

Before disassembling, always turn off the phone and remove it. SIM-This will prevent contact damage and data loss.
How to reassemble the phone after removing the lid?
Assembling Xiaomi Redmi after repair is no less important than parsing.Incorrectly installed cover can lead to poor fit, dust or even overheating of the device.
Step-by-step:
- Make sure all the connections and contacts are connected correctly.
- Clean the edges of the body and cover from glue residues with isopropyl alcohol.
- Apply a new adhesive (e.g., B-7000 or T7000) with a thin layer around the body perimeter. Don't overdo it - excess glue can get inside!
- Carefully apply the lid and press it, starting at one corner, make sure all the latches are in place.
- Then, make sure to have a sleeve and see if there are any slits.
- Leave the phone under a press (for example, under a stack of books) for 1-2 hours to grab the glue.
If the phone does not turn on after assembly, check:
- Battery connection (possibly the plume has gone).
- Integrity of the power button (sometimes it shifts when assembled).
- No short circuit (try to connect charging β if the phone is warm but not turned on, the problem is in the board).
