How to disassemble Xiaomi Redmi Note 5: instructions with photos and tips

The Xiaomi Redmi Note 5 (codenamed Whyred) remains a popular smartphone years after its release, thanks to its robust “stuffing” and self-repairability. However, disassembling this device requires caution: a thin plastic case, battery adhesive fixation and fragile plumes can turn a simple display replacement into expensive repairs. In this guide, we will examine the process of disassembling the Redmi Note 5 in steps from tool preparation to removal of the motherboard, and tell you about typical mistakes and ways to avoid them.

It’s important to understand that disassembling a smartphone is warranty-free (if it’s still in place) and carries risks of damage to the device. If you’ve never disassembled a smartphone before, work out on a broken device or go to a service center. However, even a beginner can do it to replace the battery, speaker or camera of the Redmi Note 5 disassembly, provided that instructions are followed and the right tools are used.

Preparation for disassembly: tools and security measures

Before you start disassembling, make sure you have everything you need, and even one tool that you don't have can damage the body or the internal components, and here's the minimum set:

• 🔧 Plastic mediators (2-3 pieces) - for separation of the back cover without scratches.
• 🔨 The screwdriver. PH00 — for shell screws (normal) PH0 won't fit!).
• 🔋 Suction - helps to lid the lid after heating.
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic mat or container – so as not to lose screws.
• 📱 Plastic blade - to disconnect plumes.
• 🛠️ Tweezers – to work with small details.

Also, prepare your workspace: it should be clean, well-lit and without static electricity. Put soft cloth (like a microfiber) on the table so that you don't scratch the screen or the lid. If you're disassembling a smartphone to replace your battery, buy the original battery (4,000 mAh for the Redmi Note 5) in advance, cheap ones can swell or hold no charge.

⚠️ Warning: Do not use metal tools to separate the cover! Even a slight scratching of antenna lines (located around the perimeter of the housing) can lead to loss of network signal or Wi-Fi.

Step 1: Turn off and remove the back cover

The first step is to turn off the power and remove the back panel, and even if the smartphone is discharged, the battery can retain a residual charge, which is dangerous if it accidentally circuits.

1. Turn off the Redmi Note 5 with a long press of the power button.
2. Remove the tray for SIM-cards (use a paper clip or special key).
3. Heat the back cover with a hair dryer around the perimeter for 2-3 minutes. The glue will become softer, and the cover will separate more easily.
4. Suction lid at the bottom edge (near the USB-C connector) and gently pull up.
5. Insert a plastic mediator into the resulting gap and lead them along the case, separating the lid.

If the lid doesn't lend itself, don't force it, repeat the heat. On the Redmi Note 5, the lid is not only attached to the glue, but also to the latches on the sides. When you separate properly, you'll hear the characteristic clicks. Be careful with the fingerprint scanner plume, which is glued to the lid and can come off!

Step 2: Turn off the battery and plumes

When you take the lid off, you'll see the battery, the motherboard, and some plumes, and the first thing you need to do is turn off the battery to avoid short circuits.

1. Unscrew 5 screws that fix the metal plate over the battery (use the PH00 screwdriver).
2. Take the plate off and gently tuck the battery plume into a plastic blade, which is located at the top of the battery.
3. Then, pull the wires upwards (do not pull the wires!).

Now you can turn off the other plumes:

• 📱 Display plume (at the bottom of the board).
• 🔊 Speaker and microphone plume (right of the battery).
• 📸 Main camera plume (under metal plate).

⚠️ Attention: The fingerprint sensor plume on the Redmi Note 5 is extremely fragile! If you don't plan to replace it, try not to touch this area.

Step 3: Removing the battery

The battery in the Redmi Note 5 is glued to the body, and removing it is one of the most difficult steps. If you replace the battery, be prepared for the fact that it can be bloated. In this case, do not try to pierce or bend it, it is dangerous!

Instructions for extraction:

1. Put a plastic blade on the battery from any angle, and if it doesn't lend itself, heat the body with a hairdryer (no more than 80°C!).
2. Carefully pull on a special black tape (pull-tab), if any, and in most cases, you have to put it on yourself.
3. If the battery is swollen, use isopropyl alcohol (70%+) to dissolve the glue. Apply a few drops under the battery and wait 1-2 minutes.
4. After extraction, clean the body of glue residues with alcohol or acetone.

When installing a new battery, use double-sided tape or special glue (such as the B-7000).Do not seal the battery completely - leave a small gap for pull-tab in case of future replacement.

Step 4: Withdrawal of the motherboard

The Redmi Note 5 motherboard is mounted on 12 screws of varying lengths. Remember or photograph the location of each screw -- if you confuse them when you build them, you can damage the board or the case.

1. Unscrew all screws (use a magnetic screwdriver to avoid losing them).
2. Carefully tuck the board with a plastic spatula from the edge where the connectors are located.
3. Raise the board at an angle of 30-45° and check if the plumes interfere (for example, the plume of the power button).
4. Completely remove the board and put it on an antistatic surface.

On the back of the board are located:

• 📡 Antenna modules (do not touch them with metal tools!).
• 🔋 Charging controller (often fails with short circuits).
• 📱 Memory chip (if you plan to replace, you will need soldering) BGA).

💡

If the smartphone doesn’t turn on after assembly, check if you forgot to plug in the power button plume. This is the most common mistake when disassembling the Redmi Note 5!

Step 5: Replace the display and sensor

The screen Redmi Note 5 is combined with the touch layer, so if you damage the display, you have to change the entire module. The cost of the original screen with a sensor is from 3000 to 5000 rubles (2026), but you can find quality analogues cheaper.

Replacement process:

1. Heat the screen with a hair dryer around the perimeter (temperature 70-80 ° C).
2. Put a plastic blade on the display from any angle, and be careful, there are plumes underneath the screen.
3. Disconnect the display and sensor plume from the motherboard.
4. Install a new screen starting at the top (where the speaker and front camera are located).
5. Press the display around the perimeter to fix the glue.

After changing the screen, you may need to calibrate the sensor. Go to Settings → Additional → Screen Calibration (if not available, use the engineering menu: ##6484###).

💡

When buying a new display for Redmi Note 5, pay attention to the version: screens for Redmi Note 5 Pro (code whyred) and Redmi Note 5A are incompatible!

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling the Redmi Note 5, and here are the most common ones and ways to prevent them:

• 🔧 Removing screws - use a high-quality screwdriver PH00 And don't use too much force. If the screw doesn't unscrew, drop it on it. WD-40 And wait 5 minutes.
• 🔋 Battery plume damage -- always turn off the battery first and plug in the last one. If the plume breaks off, it can be soldered, but it requires skill.
• 📱 Scratches on the body — use only plastic mediators. Metal tools leave traces that you have to paint over.
• 📡 The antenna wires break -- don't pull the camera plumes or the Wi-Fi antennas. They're soldered to the board and they come off easily.

If after the assembly of the smartphone does not turn on, check:

1. Are all the plumes connected (especially the battery and display)?
2. Are the contacts closed on the motherboard (look for foreign objects).
3. Are the capacitors near the power controller bloated (a sign that the smartphone is warming, but does not respond to charging).

⚠️ Warning: If the battery is not charged after the battery is replaced, check the thermistor (a small black sensor on the battery) which often breaks off when sloppy extraction and requires soldering.
