Disassembly Xiaomi Redmi 5 Plus: a complete guide with photos and tips

Xiaomi Redmi 5 Plus is a popular smartphone released in 2018, which is still in use today due to its reliability and good performance, but even such a device requires repair over time, whether it is a replacement battery, charging connector or screen. If you decide to disassemble the device yourself, it is important to do it carefully so as not to damage fragile components.

In this article, you will find detailed instructions on how to disassemble photos, a list of necessary tools and key warnings to help avoid typical errors. We will also tell you which parts most often fail and how to replace them without risk to the motherboard. If you are new to electronics repair, don’t worry: following our recommendations minimizes the risks.

Before you start, consider that disassembling your smartphone will void the warranty (if it's still valid) and require caution. If you're not sure about yourself, you'd better go to the service center. But if you're ready, you'll get started!

Preparation for disassembly: tools and security measures

Before you disassemble the Redmi 5 Plus, make sure you have everything you need, and inappropriate tools or haste can cause plumes to be damaged, the body chipped, or even a short circuit.

• 🔧 Set of screwdrivers (cross-haul) PH00, flat 1.5 mm, five-pointed Y00 logo-screw)
• 📱 Plastic mediators or shoulder blades (for careful smearing of the body)
• 🔥 Dryer or thermoair station (to soften the glue under the screen if replacement is required)
• 🧲 Magnetic mat or container (to avoid losing screws)
• 🔋 Antistatic bracelet (protection against static electricity)
• 📸 Smartphone for photo fixation (to remember the location of details)

Pay special attention to antistatic protection. Even a small discharge can damage delicate chips. If the bracelet is not, regularly touch a grounded metal object (for example, a heating battery), and we recommend working on a clean, well-lit surface without carpeting, which accumulates static electricity.

⚠️ Warning: Don't use metal blades to tweak the body! They can leave scratches on the aluminum frame or damage the plumes. Plastic mediators are safer.

Step 1: Shutting off power and removing the back cover

The first step is to shut down the device completely. Turn off the smartphone and remove it. SIM-This will prevent the contacts from accidentally closing during disassembly:

1. Place the smartphone down on a soft surface (such as a napkin).
2. Find two screws at the bottom of the case (near the USB-C connector) hidden under the stickers — gently tuck them in with a nail or plastic spatula.
3. Remove the screws with a five-pointed screwdriver Y00.
4. Insert a plastic mediator into the gap between the case and the screen (start at the lower right corner) and gently lead along the perimeter, separating the adhesive layer.

The back cover of the Redmi 5 Plus is attached to glue and latches. Don't put too much effort into it -- if the cover doesn't lend itself, warm it up with a hair dryer (temperature no higher than 60°C) for 1-2 minutes. This will soften the glue.

When you take the lid off, you'll see the battery, the motherboard, and the plumes. Don't touch the contacts with your bare hands -- use gloves or antistatic tweezers.

Step 2: Disconnect the battery and plumes

Before you continue disassembling, be sure to turn off the battery, which will protect the device from short circuit. On the Redmi 5 Plus motherboard, the battery connector is located at the top (near the camera), gently tuck it in with a plastic blade and disconnect the plume.

Then, turn off the other sleeves:

• 📷 Main camera plume (locker goes up)
• 🔊 Dynamics and microphone plume (attached by a latch)
• 📱 Touch screen plume (most fragile - be careful!)
• 🔋 Charging connector plume USB-C

For convenience, take a picture of the plumes before you shut them down, which will help you connect them back together correctly. Note that some connectors have protective covers (for example, on the camera) - don't lose them!

⚠️ Attention: The touchscreen plume is extremely thin, and if it's damaged, it will stop responding to touch, and it will cost you a lot to replace it. 30-50% smartphone.

Step 3: Removing the motherboard

The Redmi 5 Plus motherboard is mounted on 12 different sized screws, so you don't want to confuse them when you build them, you can put them in groups on a magnetic mat. Use a PH00 cross screwdriver and follow the algorithm:

1. Remove all screws around the board perimeter (start with corners).
2. Carefully tuck the board with a plastic spatula on the side of the USB-C connector.
3. Raise the board at an angle of 30-45° and check if the plumes (for example, antenna cables) interfere.
4. Completely remove the board and put it on an antistatic surface.

On the back of the board are located:

• 📡 Antenna modules (for Wi-Fi and cellular communication)
• 🔋 Power controller (often fails when overheating)
• 🖥️ Snapdragon 625 processor (under metal radiator)

💡

If the screws don't twist, don't force them! They may have been stuck by oxidation. Drink some alcohol or WD-40 and wait 5 minutes.

When you remove the board, be careful with flexible antenna cables, which are soldered to the board and easily detached. If the cable is detached, you can solder it back, but it requires soldering iron skills.

Step 4: Replace the battery (most common procedure)

The Redmi 5 Plus battery (BM47, 4,000 mAh) loses capacity or swells over time, and if you notice that the phone is rapidly draining or the body is deformed, it's time to replace it.

1. Unplug the old battery with a plastic spatula. Be careful, lithium polymer batteries can ignite if punctured!
2. Remove the residues of the glue from the body (you can use isopropyl alcohol).
3. Install a new battery and glue it to a double-sided scotch (comes complete).
4. Connect the plume to the motherboard and fix it.

When choosing a battery, pay attention to the originality. Counterfeiting often has an understated capacity and can damage the power controller.

• 🔋 The original Xiaomi BM47 (Best option, but expensive)
• 🔋 Baseus BAT-R5P (good analogue with overheating protection)
• 🔋 Remax RBA-40 (Budget, but check the reviews)

⚠️ Warning: If the battery is swelling, don't try to puncture it! It can cause fire. Carefully remove it and dispose of it at a special reception point.

Step 5: Replace the screen and touch module

The Redmi 5 Plus screen consists of two parts: an LCD matrix (responsible for image) and a touch layer (responsible for touching), and 80 percent of the time, the sensor suffers from a fall, but sometimes the matrix cracks, and you will need to replace it with:

1. Warm up the screen with a hair dryer (70-80°C) for 3-5 minutes to soften the glue.
2. Undercut the screen with plastic mediators, starting at the bottom edge (where the USB-C connector is located).
3. Carefully separate the sensor module from the matrix (they are glued together).
4. Disconnect the matrix and sensor plumes from the motherboard.
5. Install a new screen and glue it to a double-sided 3M 9448A tape.

The cost of the original screen for Redmi 5 Plus, about 3000-5000 ₽, analogue — 1500-2500 ₽. When buying, check whether the adhesive tape and plumes are included, as they are often sold separately.

💡

When changing the screen, be sure to check the sensor before final assembly! If touches are not recorded, the problem is in the plume or its connection.

If after replacement the screen flickers or stripes appear, the following problems are likely:

• 🔧 Bad plume contact (check the connection)
• 🔥 Overheating of the matrix during installation (let cool for 10 minutes)
• 🛠️ Marriage of a new screen (return to the seller)

Step 6: Camera disassembly and dynamics

The Redmi 5 Plus camera (main 12 MP, front 5 MP) is attached to the motherboard via a plume.

1. Unscrew two screws that fix the metal frame of the camera.
2. Carefully put the frame on and remove it.
3. Disconnect the camera plume from the board (the locker goes up).
4. Remove the camera and install a new one by fixing the frame back.

The speaker and microphone are located at the bottom of the case, and their replacement requires:

• Unscrew the screws of the metal protection mounting.
• Disconnect the plume from the board (it is combined with the USB-C plume).
• Remove the speaker and install a new one, pasting it around the perimeter.

Frequent camera problems:

• 📸 Fogging of the lens (requires replacement of glass or the entire module)
• 🔍 Blurring photos (check focus or clear the lens)
• ⚡ Artifacts in the pictures (damaged plume or matrix)

Assembly of a smartphone and checking the performance

The Redmi 5 Plus is built in reverse order, and follow these tips to avoid mistakes:

1. Check if all the plumes are tightly connected (especially the touchscreen and battery).
2. Make sure that no screws are left unnecessary (there should be exactly 12 pieces on the board).
3. Close the back cover and check if there are gaps (if any, the glue is not warmed enough).
4. Turn on your smartphone and test all the functions: touch, camera, speaker, charging.

If after assembly the smartphone does not turn on:

• 🔋 Check the battery connection (possibly the plume is not fully inserted).
• 🔌 Connect the charger – sometimes forced charging is required (hold on Power) + Volume Up 10 seconds).
• 🛠️ If the indicator does not burn - a problem with the motherboard is possible (diagnosis is required).

💡

After replacing the battery or screen, the smartphone may show an incorrect charge level for the first 2-3 charging cycles.
