Modern smartphones are becoming more complex devices, and the Xiaomi Redmi 10 is no exception. The need to open the case can arise for various reasons, from the banal replacement of a broken screen to more complex operations, such as replacing the battery or repairing the charging connector. However, before you start taking up the tools, it is important to understand that opening the case automatically voids the manufacturer's warranty if it has not expired.
The disassembly process requires not only special tools, but also a certain amount of caution, since the internal components are very tightly arranged. Unlike older models, where the back cover was removed easily, modern gadgets are assembled using a large amount of glue and hidden screws. The glue under the back cover of the Redmi 10 softens only at a temperature of 80-90 ° C, heating below this mark will not work. Wrong actions can lead to damage to plumes or cracks on the glass.
In this guide, we will take a detailed look at each step of dismantling, from the preparation of the workplace to the unplugging of the core modules, you will learn which tools are really needed and which can be dispensed with, and we will pay special attention to safety when working with lithium polymer batteries, which can be dangerous to damage.
Workplace preparation and necessary tools
You can't do a good job of disassembling without a properly organized space. You'll need a clean, well-lit table, preferably with antistatic coating or just no pile, so that the small cogs don't get lost in the dust. Light should fall evenly, without creating glare on the glossy surfaces of the screen, allowing you to see the fine details and fasteners.
The toolkit should be specialized. The use of kitchen knives or sewing needles is highly undesirable, as they can damage plastic or scratch metal. To work with Redmi 10, you will need a minimum gentleman's set of masters.
- 🔧 A set of precision screwdrivers (mandatory presence of bits) PH000 Pentalobe, if any, although Redmi 10 is more likely to use crosses).
- 🔥 Hair dryer or thermoplatform for heating adhesive (heating temperature should not exceed 100)°C to avoid damage OLED-matrix).
- 🎴 Plastic mediators, suction cup and thin metal scalpel (for primary autopsy).
- 🧲 Magnetic mat or organizer for screws, so as not to confuse them when assembling.
Special attention should be paid to safety. Before starting any work, you need to completely turn off the device. If the screen is broken and does not respond to touch, press the power button for 10-15 seconds to force the switch off. Working with the device on can lead to a short circuit on the board, which is often fatal for the power controller.

Removal of the back cover and dismantling of protective elements
The most difficult step for beginners is to carefully remove the back panel. In the Xiaomi Redmi 10 model, it is attached to a two-part glue around the perimeter. Start by heating the edges of the body with a hairdryer, warming the surface evenly for 2-3 minutes. Don't hold the hairdryer at one point for too long to overheat the battery.
⚠️ Warning: Never try to cover the cell area or the center of the enclosure, where there are internal elements that can be easily damaged by a sharp tool.
Once warmed up, use a suction cup to create a small gap between the frame and the lid. Insert a plastic mediator or a thin blade into this gap carefully. The movements should be sliding, not stabbing. Lead the instrument along the perimeter, gradually cutting the adhesive layer. If you feel strong resistance, heat the area again.
Once the lid is separated, don't try to remove it completely. Inside, there may be plumes going to the control modules or the fingerprint scanner (if integrated into the side button, but in this model, the scanner is often on a separate plume or combined with a button).

Disconnection of the battery and removal of the protective panel
When you successfully remove the back cover, you'll see the interior layout, and in Redmi 10, most of the space is occupied by a battery, and on top of it, it's covered with a plastic protective lining, which also has a speaker and plumes, and the first thing you need to do is visualize the situation before any screws are unscrewed.
The plastic shield is mounted with a lot of screws of different sizes, usually around the perimeter and in the center, and you can twist them in sequence, fold them into individual cells, and some screws can be hidden under stickers or plugs, so be careful.
The most important rule is that the battery is always turned off first. Even if you only need to replace the speaker or the camera, de-energizing the board is a must. Find the battery connector on the motherboard and gently tuck it in with a plastic blade. Don't use metal to keep the circuit board in contact.
- 🔋 Disconnect the battery plume with a light swaying upward movement.
- 🔌 Disable the main camera module plume if it interferes with access to other components.
- 📡 Remove the antenna module if it is fixed on the inside of the cover.
- 🔊 Carefully remove the vibromotor, which is often glued or sits tightly in its lodging.
Once you've turned off all the visible plumes, you can remove the main plastic lining, it can sit tight because of the glue dots, use a dryer for easy warming up and a mediator for separation, and be careful with the tail of the side button that can be glued to this lining.
💡
Before removing any board or module, take a picture of their location on the phone, which will help you remember exactly how the plumes were and where the screws were, especially if you are doing this for the first time.
Dismantling of motherboard and modules
The motherboard in Xiaomi Redmi 10 is located at the top of the case. It's secured by screws and protected by metal screens that are soldered or screwed. Access to connectors and components often requires removing these screens, but it's not usually required to replace the display or battery.
To remove the board, you have to disconnect all the plumes that go to it. These are the display plume, the lower board plume (with the charging connector), the antenna cables (if they go separately) and the button plume. Antenna cables (coaxial) have round connectors that you need to pull very carefully from the bottom, trying not to damage the wire itself.
Turn all the screws that hold the board to the frame. Notice the screws of different lengths: a short screw screwed into a long hole can pierce the board and damage the components on the back. Always check the length of the screws.
| Component | Type of attachment | Features of withdrawal | Risk of damage |
|---|---|---|---|
| Maternity fee | Screws + plumes | Requires antennas to be turned off | Tall (a lot of small electronics) |
| Display module | Glue + frame | Perimeter heating needs. | Critical (fragile glass) |
| Battery | Clay (bilateral) | It's hard to pull, you need a lever. | Medium (puncture risk) |
| Lower fees | Screws + plume | Simple attachment | Low. |
When you remove the board, gently lift it, check if any small plume is caught. The board should come out freely. Place it on an antistatic surface or in a safe place, away from metal objects.
💡
The order of shutdown of the plumes is critical: first the power (battery), then everything else. The order of connection during assembly is reversed: first the plumes, then the battery.
Replacement of the display and work with the frame
If your goal was to replace a broken screen, it's a little bit different. In Redmi 10, the display is glued to a plastic frame. Changing the glass separately at home is extremely difficult and risky, so you usually change the entire module assembled with a frame or reglade the old display to a new frame.
Removing the display from the frame (if you bought a frameless module) will require reheating around the perimeter. Use a string or a thin line to cut the adhesive layer between the display and the frame. The movements should be smooth, without jerking.
After the old display is separated, you need to carefully clean the frame of the glue residue. Use isopropyl alcohol and a plastic card to do this. The surface must be perfectly smooth, otherwise the new screen will lie uneven and may crack at the first press.
⚠️ Warning: When you install a new display, don't glue it to the top. First, plug in the plume, turn on the phone, check the touchscreen and the image. Make sure it works, apply the new glue (B-7000 or analogue) and press the module.
The assembly is done in reverse order. Make sure the display plume snaps to the characteristic click. An insufficiently connected plume is a common cause of a black screen or a broken touchscreen after assembly.
Nuances of work with the battery and its replacement
Replacing the battery in the Xiaomi Redmi 10 is complicated by the fact that it occupies almost the entire interior area and is attached to a powerful layer of glue. Trying to simply tamper with a screwdriver can lead to deformation of the battery case, which is strictly forbidden.
To extract safely, use a suction hood or a plastic lever. If you use a lever (like an old credit card), insert it between the battery and the case, trying not to damage the plume going from the bottom.
The chemical method of facilitating removal involves injecting isopropyl alcohol under the battery through special holes (if any) or around the perimeter. Alcohol dissolves the glue, making the battery movable. However, in Redmi 10, the design may not involve convenient holes, so the mechanical method of heating remains the main one.
- 🌡️ Heat the battery area with a hairdryer to 60-70°C (no more so that the electrolyte does not boil).
- 🧵 Use a line to cut the glue under the battery if it sits very tightly.
- 🚫 Never use metal tools to pick under the battery.
- 🗑️ Recycle old battery according to safety rules, do not throw in the general garbage.
The new battery before installation is also desirable to warm up slightly so that the glue is better grasped, or use a special adhesive layer (pre-cut adhesive), which can be purchased separately, this will ensure tightness and fixation.
Device assembly and initial start
The final step is assembly. Take a close look at all the components. Make sure the plumes are free of clogs and the connectors are free of dust. Collect a sandwich from the bottom board, the battery and the plastic pad, and twist all the screws.
Connect the battery plume to the motherboard, and then you can plug the other plumes (display, buttons, cameras) into the battery, and turn the device on without screwing the back cover to check that all systems, sound, vibration, touchscreen and cameras, are working.
If everything works, apply a new layer of glue (B-7000) to the frame of the case in a thin strip. Let the glue dry slightly (1-2 minutes), then gently press the back cover. For better fixation, you can use stationery gums, wrapping them around the phone for 15-20 minutes, but not too tight to avoid deforming the screen.
After you've fully assembled and dryed the glue, turn on your phone and check the proximity sensor and the fingerprint sensor, and if the scanner doesn't work, you may have misconnected the plume or damaged it during assembly, and then you'll have to repeat the procedure.
