Disassembly of the Xiaomi Redmi 8 Pro smartphone may be necessary to replace the battery, repair the display or clean up dust. However, this process requires care and proper preparation - one wrong movement can damage plumes or chips. In this article, we will discuss in detail how to disassemble the device without risking to disable it, what tools will be required and what to pay attention to.
The Redmi 8 Pro (codenamed Olivelite) differs from the standard Redmi 8 with an improved camera and some hardware improvements, but the body design remains similar, which means that the manual will also fit the basic version, but taking into account the nuances of the layout of the components. If you have never disassembled a smartphone before, we recommend you first practice on a non-functional device or watch video reviews from experienced craftsmen.
Preparation for disassembly: tools and security measures
Before you start disassembling, make sure you have everything you need, and using the wrong tools is the main cause of damage to the body or internal components, and here is the minimum set you'll need:
- 🔧 Plastic mediators or shoulder blades (thickness 0.2–0.4 mm) for disengagement of the housing.
- 🔨 A cross screwdriver the size of PH00 or PH0 screw.
- 🧲 Magnetic mat or container for storing small parts.
- 🔥 Dryer or thermo-air station (to soften the glue under the back cover).
- 📱 Suction (optional, to lift the display module).
- 🧴 Isopropyl alcohol 90%+ (clean-up).
Important: Redmi 8 Pro is made on adhesive basis, so without heating the back cover is almost impossible to remove.°C, otherwise you can damage the battery or plumes. Also, turn off the smartphone in advance and remove it. SIM-Memory card – this will save data from accidental damage.
⚠️ Warning: If the battery is swollen or deformed, it is better to trust the dismantling to professionals.
Step 1: Removing the back cover
The Redmi 8 Pro's back panel is glued around the perimeter, so it needs to be heated carefully.
- Put the smartphone on a flat surface with the screen down.
- Heat the back cover in a circle for 2-3 minutes, holding the nozzle at a distance of 5-7 cm.
- Insert a plastic mediator into the gap between the lid and the case (start at the lower corner where the charging connectors are located).
- Carefully swipe the mediator around the perimeter, separating the glue. Don't put too much effort into it -- if the lid doesn't lend itself, heat it up again.
When you remove the lid, you'll see the battery, the motherboard and the plumes. Don't touch the metal parts with a screwdriver, it can cause a circuit. If the glue is left on the case, remove it with alcohol or a special cleaner.

| Component | Location. | Features |
|---|---|---|
| Battery | Central part | Sticked, has a power plume. |
| Maternity fee | Under the battery. | Fixed with screws, connected to the display plume |
| Camera. | Upper left corner | 4 modules covered by a metal frame |
| Dynamician | The bottom part | Fixed to a bilateral scotch |
Step 2: Shutting off the battery
Before any manipulation with the internal components, be sure to disconnect the battery.
- Find the battery power plume (usually black and located next to the motherboard).
- Put a plastic scapula or a nail on the jack, pull it up. Don't pull the wires!
- Make sure the contacts are not closed – you can check with a multimeter (voltage should be 0 V).
If the battery is swelling, you can't force it off, it can cause it to rupture. In such cases, you'd better go to the service center. Also note the flexible plume that connects the board to the display, which is easily damaged when you're not moving sloppy.
⚠️ Warning: After the battery is turned off, the smartphone is completely powered down. Do not turn it on until the assembly is complete - this can burn the components.
💡
If the battery connector fails, take a picture of the battery's position before you try to disconnect, which will help you plug it back in correctly.
Step 3: Removing the motherboard
The Redmi 8 Pro motherboard is mounted with multiple screws and connected to other components by plumes to remove it:
- Unscrew all the screws (usually 6-8 pieces) and fold them in a separate container.
- Disconnect the plumes: 📱 Display plume (at the top of the board). 🔊 Dynamic plume (bottom). 📶 Antenna contacts (sides).
Carefully raise the charge, starting at the top edge, and if it's stuck, check if all screws are unscrewed.
On the back of the board are the memory chips and the Qualcomm Snapdragon 439 processor. Don't touch them with your fingers, static electricity can knock out the chips. If you need to replace components (such as a charging connector), you'd better pay the fee to a soldering workshop.

Step 4: Replace the battery (Step-by-step)
The Redmi 8 Pro battery has a capacity of 5000 mAh and is glued to the body.
- Heat the battery with a hair dryer (temperature 60–70°C) for 1-2 minutes.
- Put a plastic blade on it from any angle, and if the glue is too strong, use a thread or a special glue solvent.
- After extraction, clean the contacts with alcohol and install a new battery, having previously removed the protective film.
- Connect the power plume and check the voltage with a multimeter (should be 3.7-4.2 V).
Important: The new battery must be original or certified, cheap fakes may swell or not hold a charge, after replacement, calibrate: fully discharge and charge the smartphone 2-3 times.
💡
When installing the battery, make sure that the plume is not bent or clamped with the body.This can lead to overheating or failure to charge.
Step 5: Disassembly of the display module
The Redmi 8 Pro display is paired with a touchscreen and glued to the frame.
- Heat the screen around the perimeter (temperature 70-80 ° C).
- Use a suction cup to lift the module. If the glass is cracked, paste it with tape so that the fragments do not fall apart.
- Disconnect the display plume from the motherboard (it is fixed by a latch).
- Install a new module, pre-cleaning the contacts with alcohol.
If the device does not turn on after assembly, check:
- Connecting the battery and display plume.
- Integrity of contacts on the motherboard (possibly contaminated or oxidized).
- Correct installation of antenna modules (lack of network signal is a sign of poor contact).
💡
Once assembled, reset (Settings → About Phone → Reset) if the smartphone is unstable, which will help avoid software conflicts.
