How to properly disassemble the Xiaomi Redmi phone: instructions for beginners

Preparation for disassembly: what you need to know before the beginning

Disassembling the Xiaomi Redmi smartphone is a challenge that owners face when replacing the battery, display or cleaning from dust. However, this process requires accuracy and understanding the internal device, which can lead to damage to the plumes, disconnection of contacts or even complete failure of the device.

Before you start, evaluate your skills. If you have never held a Pentalobe screwdriver or do not know where the flexible battery plume is, you should contact a service center. For experienced users, disassembling Redmi (be it the Note 10 Pro, 9T or Redmi A2) will not be difficult with the right approach.

Required tools for disassembling Xiaomi Redmi

Without the right tools, it is almost impossible to disassemble the Xiaomi Redmi.

• 🔩 Pentalobe screwdriver P2 — for back cover screws (newer models often use Torx screws) T3 or Y000)
• 🔧 Plastic blades/mediators – to separate the cover and plumes (metal tools can scratch the body)
• 🔋 Suction - helps to lift the display or back panel after warming up
• 🔥 Dryer or thermo-air station - for softening the glue (temperature not higher than 80)°C!)
• 🧲 Magnetic mat or organizer - in order not to lose screws (in Redmi there can be up to 15 pieces of different lengths!)
• 📏 Plastic tweezers - for careful disconnection of plumes

For models with a non-removable battery (for example, Redmi Note 11) additionally require:

• 🔪 Special glue for batteries (e.g, B-7000) — If you plan to collect the phone back
• 🛠️ Isopropyl alcohol (90%+) — remove the residues of old glue

⚠️ Warning: Don't use knives or screwdrivers to jack the lid - it's almost guaranteed to damage the latches! 9A Redmi 8 plastic clips break especially easily.

Step-by-step: how to remove the back cover

The disassembly process starts with the rear panel being removed, and most Xiaomi Redmi models have it glued together, so you'll need heat treatment.

Step 1 Turn off the phone and remove it. SIM-If the battery is swelling, don't warm up the case, you're at risk of fire.

Step. 2. Warm up the edges of the back cover with a hairdryer during 2-3 minutes, keeping him at a distance 5-7 See temperature — 60-80°C. Don't overheat! in the Redmi Note 10 Pro at higher temperatures 90°C may be damaged. OLED-display.

Step 3: Put a plastic lid on the lid starting at the bottom edge (near the USB-C connector). If the lid doesn't lend itself, warm up again. Redmi 9 and newer models often use double-sided tape, which is harder to separate.

Step 4: Carefully remove the lid as you move around the perimeter. Don't pull too much - there may be antenna plumes inside (in Redmi Note 12, they are glued to the lid).

Disconnection of the battery and plumes: critical moments

Once you remove the lid, you'll see the battery, the motherboard, and a few plumes. First rule: always turn off the battery before you use the other components!

Step 1: Unscrew the screws that lock the metal battery plate (usually 4-6 Phillips #00 screws). In the Redmi Note 10S, the plate can be glued — gently tuck it into the shoulder blade.

Step 2: Unplug the battery connector with plastic tweezers. Don't pull the wires! In Redmi 9s and later, the connector is often fixed with a latch, and you have to lift it first.

Step 3. Turn off the other plumes:

Display (usually at the top of the board)

Camera (can be 2-3 plumes in Redmi Note 12 Pro)

Power/volume button (in some models integrated into the motherboard)

⚠️ Attention: Redmi Note 11 The Pro plume is extremely fragile. If it's damaged, it'll cost you to replace it. 30-50% Use an antistatic bracelet or periodically touch a grounded object to avoid static discharge.

💡

Before you unplug the plumes, take a picture of their location on the board, which will help you connect them back together correctly, especially if you're disassembling Redmi for the first time.

Disassembly of the motherboard and other components

If you need to get to the motherboard (for example, to replace the USB-C connector or microphone), act as carefully as possible. At Xiaomi Redmi, the fee is often fixed on double-sided scotch and screws.

Procedure:

1. Unscrew all screws around the perimeter of the board (in Redmi Note 10 Pro there are 12 pieces of different lengths!).
2. Carefully tuck the board with a plastic blade, starting at the top edge. Don't use force, there may be antenna contacts under the board.
3. Disconnect the remaining plumes (speaker, vibrator, charging connector).
4. Remove the board and put it on an antistatic surface.

In NFC models like the Redmi Note 12, the antenna is often integrated into the back cover, and if you damage it, contactless payments will stop working.

What can be replaced by yourself:

• 🔋 Battery (the most frequent case)
• 📸 Main/front camera
• 🔊 Dynamician or microphone
• 🔌 Connector. USB-C/3.5 mm (in models with audio connector)

What is better not to touch without experience:

• 📱 Display (requires special glue and press)
• 🔄 Folding plumes (in Redmi Note 11 their replacement is difficult due to the thin contacts)
• 🔋 Power controller (short circuit risk)

💡

If you're disassembling a battery replacement phone, never use superglue to fix a new one! only special battery glue (like the T7000 or B-7000).

Common Mistakes in Disassembly and How to Avoid Them

Even experienced craftsmen sometimes make mistakes that lead to breakdowns.

• 🔥 Overheating of the body - leads to detachment of the display or damage to the plumes. in the Redmi Note 12 Pro+ OLED-The screen is particularly sensitive to temperature.
• 🔩 Loss or tangle of screws, screws of different lengths, if you screw a long screw into an unintended place, you can break through the board.
• ⚡ Working without turning off the battery - the risk of short circuit in case of accidental closure of contacts.
• 📱 Display plume damage – 80% of cases lead to white screen or stripes.
• 🧲 Using metal tools – scratches the body and can close contacts.

To avoid problems:

• Work on a clean, well-lit surface.
• Use a magnifying glass to work with small details.
• If the plume does not disconnect, do not pull it - check if there is a fixing latch.

⚠️ Attention: At Redmi 10A redmi 9C There's a common defect: if you disassemble the power button, the contact area breaks off. If the phone doesn't turn on after assembly, check this point!

Build the phone back: nuances and verification

Building Xiaomi Redmi after a showdown is as important as disassembling.

1. Check all the plumes — they should be tightly inserted into the connectors. In the Redmi Note 11 Pro, the main camera plume often falls out when assembled, resulting in a black camera screen.

2. Secure the battery:

In models up to Redmi 9, use the original double-sided scotch.

In new models (Redmi Note 12) apply the glue B-7000 thin layer around the perimeter.

3. Twirl the screws in the correct sequence:

First, they are angular (they fix the fee).

- Then along the perimeter.

- Last of all, the screws of the lid.

4. Check the functionality before final assembly:

Turn on the phone (if not turned on, check the battery and power button).

- Make sure it works:

- Sensor and display

- Cameras (front and main)

- Sound (speaker and microphone)

- Network (SIM-map, Wi-Fi)

If something doesn't work, reassemble the phone and check the contacts and plumes, and 90 percent of the time, the problem is a poorly connected component.

💡

After assembly, allow the battery glue to dry for 1-2 hours before first turning on, which will prevent the battery from shifting when heated.
