Disassembling the Xiaomi Redmi Note Pro is a challenge that owners face when replacing a battery, display, speakers or other components. Despite the apparent complexity, the procedure is even possible for beginners, if you follow the proven instructions and use the right tools. The main thing is to understand that each model of the Redmi Note Pro series (from Pro 3 to Pro 12) has its own design features: somewhere the glue is applied point-only, somewhere β solid layer, some versions are equipped with a glass back panel, others β plastic.
In this article, we will discuss the universal disassembly algorithm that is relevant for most line models, and also point out key differences between generations. You will learn how to safely remove the back cover, disconnect the plumes and avoid damage to flexible cables. Special attention will be paid to the Redmi Note 10 Pro model with IP53, its protection from dust and moisture complicates disassembly, but does not make it impossible. If you plan to repair with your own hands, this guide will help save on the service center and avoid typical errors.
Preparation for disassembly: tools and precautions
Before you start, make sure you have everything you need, and without the right tools, the risk of damage to the body or internal components increases dramatically.
- π§ Plastic mediators (2-3 - for gently putting the lid on. Metal tools can leave scratches.
- π₯ Dryer or thermo-air station - for softening the glue (temperature 60-80)Β°C) Even a household hair dryer at maximum power will work.
- β‘ Suction cup - helps to raise the back panel after heating. It is better to use a small one (diameter 3-4 cm).
- βοΈ Thin knife or scalpel β for cutting glue in hard-to-reach places (for example, near volume buttons).
- π¦ Container for screws β magnetic substrate or tray with cells, so as not to lose small parts.
- π Screwdriver. T3/T4/T5 β for twisting screws (new models often use screws with protection against vandalism).
Also, prepare the workplace: the desk should be clean and well lit. It is advisable to use an antistatic mat or at least an earthed surface to avoid damage to the chips by static electricity. If you disassemble the Redmi Note Pro with a faulty battery, do not connect it to charging - this can lead to fire.
β οΈ Note: Redmi Note 8 Pro and later have an L-shaped battery plume with fragile contacts!
Step 1: Removal of the back cover β heating and slashing technique
The Redmi Note Pro's back panel is attached to the glue, and you can't just take it off, and the main goal is to heat the body evenly so that the glue becomes elastic.
- Turn off your smartphone and remove it. SIM-card from the tray (if any).
- Heat the hair dryer back cover around the perimeter for 2-3 minutes, holding the nozzle at a distance of 5-7 cm Pay special attention to the corners - there the glue is applied more densely.
- Push to the center of the lid (near the camera) and pull up. If the lid doesn't respond, repeat heating.
- Insert the mediator into the gap and carefully guide it along the body, separating the glue. Do not press too hard - you can damage the fingerprint plume (in models with a sensor on the back).
The Redmi Note 10 Pro and the newer one have a glass back, so the heat needs to be more delicate. Temperatures above 80Β°C can cause cracks. If the lid cracks when removed, it can be replaced β the original parts cost between 800 and 1500 rubles depending on the model.
βοΈ Checklist before lid removal
β οΈ Note: In the models Redmi Note 7 Pro and Note 8 Pro under the back cover hidden plume NFC-If you take it off carelessly, it's easy to tear!
Step 2: Shutting down the battery β why itβs critical
Once the lid is removed, the first thing to do is disconnect the battery, which will prevent short circuits from being shorted as you disassemble it further. Most Redmi Note Pro models have the battery plugged in via a battery. FPC-A plug (flexible plume) with a latch to disconnect it:
- Find the battery connector β it is usually located at the bottom of the board, next to the vibration motor.
- Carefully tuck the latch with a plastic pickup or tweezers.
- Make sure the connector contacts are not bent. If they are deformed, the battery may not charge after assembly.
In some models (for example, Redmi Note 5 Pro) connector soldered to the board, in this case, you do not need to turn off the battery, but you should work with the device extremely carefully, avoiding screwdriver closures.
| Model | Type of battery connector | Features |
|---|---|---|
| Redmi Note 3 Pro | soldered | A soldering iron is required to shut down. |
| Redmi Note 4/4X | FPC with a latch | Fragile plume, easily broken |
| Redmi Note 7/8 Pro | FPC with a latch | The connector is located under a metal screen |
| Redmi Note 10 Pro | FPC with a latch | Additional glue on the plume |

If the latch of the battery connector breaks, it can be replaced with a similar one from the donor board or fixed with a drop of superglue (but this is a temporary solution).
Step 3: Removing the motherboard β working with screws and plumes
The Redmi Note Pro motherboard is mounted on screws and hidden under a metal screen (in the new models) to remove it:
- Unscrew all the screws around the perimeter of the board. In the Redmi Note 9 Pro and later, some screws can be hidden under stickers.
- Disconnect all plumes: π± Display plume (the widest, at the top of the board). π Speaker and microphone plume (usually at the bottom). πΆ Antenna cables (thin, glued to the body).
Carefully raise the board, starting at the top edge, and if it's stuck, make sure you've forgotten to disconnect the plume.
In the Redmi Note 11 Pro and 12 Pro, the board is additionally fixed with latches on the sides, and you need to bend them with a flat screwdriver. Be careful, if you press hard, you can damage the contact areas on the board.

Step 4: Battery Dismantling β How Not to Start a Fire
The battery in the Redmi Note Pro is glued to the body with double-sided tape or special glue to remove it:
- Put a plastic blade on the battery from any angle. Don't use metal tools, they can puncture the battery!
- If the battery fails, heat the body with a hair dryer (50-60 Β° C).
- Put a thin plastic card under the battery and slowly lead it along the case, separating the glue.
In the Redmi Note 10 Pro and later, the battery is often glued to graphite tape, which conducts heat, it needs to be carefully cut with a knife without touching the battery itself. If the battery is swelling, do not try to disassemble it β dispose of according to the rules of recycling lithium-ion batteries.
β οΈ Warning: If the battery is damaged, it can produce a caustic smoke. Work in a ventilated room and keep baking soda on hand (it neutralizes lithium).
π‘
Never throw an old battery in the trash β take it to a battery reception center or Xiaomi service center.
Step 5: Display module disassembly β when you need to change the screen
If you're disassembling the Redmi Note Pro to replace the display, you need to remove the motherboard, and it's attached to the glue and held by a metal frame.
- Heat the front of the smartphone (from the screen) for 3-4 minutes.
- Subdense the display with a plastic mediator, starting at the bottom edge (where the plume is located).
- Carefully separate the screen from the body, making sure not to break the backlight plume.
- Disconnect the display plume from the board (if it is not already removed).
In the Redmi Note 8 Pro and later, the display is often assembled with touchscreen and glass. If only the glass is cracked, it can be replaced separately, but this requires special equipment (laminator).
| Model | Screen type | Cost of replacement (original), β½ |
|---|---|---|
| Redmi Note 5 Pro | IPS LCD, 5.99" | 2500β3500 |
| Redmi Note 8 Pro | IPS LCD, 6.53" | 3500β4500 |
| Redmi Note 10 Pro | AMOLED, 6.67" | 5000β7000 |
| Redmi Note 12 Pro | AMOLED, 6.67, 120 Hz | 7000β9000 |
Common Mistakes and How to Avoid Them
Even experienced masters sometimes make mistakes when disassembling Xiaomi Redmi Note Pro. Here are the most common of them and ways to prevent them:
- π§ Broken latches of plumes - never pull the plume itself, only the plastic latch.
- π₯ Overheating of the case β do not heat one place for more than 20 seconds, otherwise the plastic will deform.
- β‘ Short circuit β before working with the board, touch the grounded object to remove static electricity.
- π± Display plume damage β do not bend the screen more than 90 timesΒ° disconnect.
- π Battery puncture β use only plastic tools to extract it.
If after the assembly of the smartphone does not turn on, check:
- Is the battery connected (sometimes the plume leaves when installing the board).
- Are the contacts bent on the connectors?
- Are there any foreign objects (screws, pieces of glue) left inside the body?

If the camera or speaker doesn't work after the disassembly, chances are you forgot to plug in the appropriate plume.
