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

Disassembling the Xiaomi Redmi Note 5 is a challenge that owners face when replacing the battery, repairing the display or cleaning the dust. Despite the apparent complexity, the procedure can be performed independently if you act carefully and use the right tools. However, it is important to understand that improper disassembly can lead to damage to the plumes, loss of leakage or even breakage of the board. This article will help avoid typical errors and conduct the process as safely as possible.

The Redmi Note 5 (codenamed whyred) differs from its predecessors in its more sophisticated rear cover, glued to the body. Unlike the removable batteries in the old Redmi, it requires patience and special mediators. If you have never disassembled a smartphone, practice on an unnecessary device or watch video instructions before you start working.

In this article, we will look at:

• 🔧 What tools will be needed to disassemble
• 📱 Step-by-step process of removing the back cover and battery
• ⚠️ The main risks and how to avoid them
• 🔄 How to assemble the device back without consequences

Preparation for disassembly: tools and materials

Before you start disassembling the Xiaomi Redmi Note 5, make sure you have everything you need. Not even one tool can complicate the process or cause damage.

• 🔨 Plastic mediators (2-3 (a) - for the separation of the lid
• 🔧 The screwdriver (PH00 or PH0) — screw
• 🧲 Suction cup – helps to lift the cover after heating
• 🔥 Hair dryer or thermo-air station - for softening the glue
• 🧴 Isopropyl alcohol (90%+) — glue-cleaner
• 📦 Logs for screws - so as not to lose small details

If you don't have a thermal air station, a normal hair dryer is fine, as long as it can heat the air to 60-70°C. Don't use metal tools to separate the lid: they can scratch the body or damage the plumes. Also prepare a clean workspace with good lighting - small parts are easily lost on dark surfaces.

Critical: In the Redmi Note 5, the fingerprint scanner plume is glued to the back cover. It's easy to tear if you don't have a neat compartment. If you're not planning on replacing this module, be very careful about the top of the lid.

💡

Before disassembling, completely discharge the battery (up to 0%) and leave the smartphone off for 10-15 minutes.This minimizes the risk of short circuit in case of accidental contact with the board.

Removal of the back cover: heating and separation

The most important step is to separate the back cover, and it's glued all around the perimeter, and a strong mechanical impact can damage the body.

1. Heat the edge of the back cover with a hair dryer around the perimeter for 2-3 minutes, keeping it at a distance of 5-7 cm The temperature should be comfortable for the hand (do not burn!).
2. Apply the suction cup to the bottom of the lid (near the USB-C connector) and pull up slightly. If the lid doesn't lend itself, warm up again.
3. Insert a plastic mediator into the gap and carefully guide it along the edge, separating the glue. Take your time - it is better to spend an extra 5 minutes than break the latches.

Pay special attention to the area around the camera and the fingerprint scanner, and there are plumes that are easily damaged, and if the lid is difficult to separate, warm up the problem area again. Don't try to tear it off by force!

⚠️ Warning: Do not use a knife or other sharp objects to separate the lid.Even a slight slip can punctur the battery or damage flexible plumes.

3. Battery disconnection and work with the board

When the lid is removed, the first thing you need to do is turn off the battery to avoid short circuits.

1. Carefully apply the battery plume with a plastic mediator (it is located at the bottom of the device, under a black film).
2. Unplug the connector from the motherboard.
3. Secure the plume with tape or put it to the side so that it does not interfere with further work.

Now we can start dismantling the other components, and if you want to replace the battery, you'll have to take it out of the case.

• 🔧 Unscrew 4 screws that fasten the metal plate over the battery.
• 🧴 Apply isopropyl alcohol under the battery (it will dissolve the glue).
• 🪛 Put the battery with a plastic spatula and take it out carefully.

Do not use metal tools to remove the battery, this can cause it to puncture and ignite. If the glue is too strong, repeat the procedure with alcohol 2-3 times.

💡

All the screws in the Redmi Note 5 are different lengths, and if you mix them up, you risk damaging the board or the case when you build them, using a cell tray or sticking a layout on paper.

4.Typical mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when disassembling the Xiaomi Redmi Note 5. Here are the most common problems and ways to prevent them:

• 🔋 Battery damage occurs when using metal tools. Always use plastic mediators.
• 📶 The antenna plumes are broken, they're on the sides of the body. Don't pull the lid up too much.
• 🔧 Loss of screws: There are over 20 screws of varying sizes in the device.
• 🌡️ Overheating boards, with prolonged heat with a hairdryer. Keep the temperature at 70.°C.

Another common mistake is the wrong build, like forgetting to plug in the fingerprint scanner plume or the speaker, so to avoid that, take a picture of each stage of the disassembly or videotape the process, which will help you keep parts in mind when you build them back.

If the device does not turn on after assembly, check:

1. Is the battery on?
2. Are the display plumes and power buttons damaged?
3. Are all the screws twisted (uncut can cause a circuit).

⚠️ Note: If the touchscreen is not working properly after disassembly (for example, spontaneous pressing), the display plume is likely to have been damaged.

5. Battery replacement: nuances and recommendations

One of the most common reasons Redmi Note 5 disassembly is to replace the battery. Over time, the battery capacity decreases and the device begins to run out quickly. The new battery must be original or certified, cheap analogues can swell or not hold the charge.

Replacement process:

1. Remove the old battery (as described above).
2. Clean the seat from the residues of glue with alcohol.
3. Apply a new double-sided scotch (combined with the battery) or a special B-7000 glue.
4. Install a new battery and press it for 1-2 minutes for reliable fixation.

After replacing the battery, be sure to calibrate it:

1. Charge your smartphone to 100%.
2. Turn off the charge and use the device until it is completely discharged.
3. Repeat the cycle 2-3 times.

This will help the power controller to correctly determine the capacity of the new battery.

Buy the original battery (article: MB41 or MB42)

Prepare isopropyl alcohol and plastic tools

Backup of data (in case of errors)

Charge your smartphone to 30-50% before dismantling-->

6. Assembly of the device: the reverse process

Getting the Xiaomi Redmi Note 5 back together is often harder than disassembling, and it’s important to follow the reverse sequence and make sure all components are connected correctly.

• 🔌 All plumes (display, cameras, buttons) are connected to the motherboard.
• 🔋 The battery is securely fixed and its plume is not bent.
• 🔧 All screws are twisted into their places (use photos taken during disassembly).

When installing the back cover:

1. Apply new adhesive around the perimeter of the case (you can use B-7000 or double-sided tape).
2. Line the cover and press it gently, starting from the USB-C connector area.
3. Warm up the hair dryer of the edge of the cover for better fixation (temperature 50-60 ° C).

After assembly, turn on the device and check:

• 📵 Whether the network is working (sim card is determined).
• 🔊 Sound in speakers and microphone.
• 📷 Camera and fingerprint scanner.
• 🔋 Charging and battery indication.

If something does not work, disassemble the device again and check the connection of the corresponding plumes.

7. when is it better to contact the service center

Despite the fact that the dismantling of the Xiaomi Redmi Note 5 is possible at home, there are situations when it is better to trust the professionals:

• 💻 Problems with the motherboard (not turned on, not charged, overheating).
• 🌊 Liquid intake - ultrasound cleaning is required.
• 📡 Problems with antennas (no network, Wi-Fi is not working).
• 🔧 Cracks on boards or cliffs of tracks.

You should also contact the service if you:

• Not sure about their skills.
• Damaged the plumes during the disassembly.
• You can't find the original parts.

The cost of disassembly in the service center is usually 500-1500 ₽ (It's not that expensive when you compare it to the risk of permanently breaking the device.

💡

If you don't turn on your smartphone after you disassemble it yourself, don't try to "fix" it by disassembling it again. You're at risk of making the problem worse. Talk to your doctor about what you've done before, and that will save them time for diagnosis.
