Disassembly Xiaomi Mi 5s Plus: instructions with photos and repair tips

Xiaomi Mi 5s Plus is the flagship smartphone of 2016, which is still popular today due to the powerful hardware and metal body. However, over time, even such reliable devices have problems: battery discharge, speaker fails or screen cracks. If you decide to repair the device yourself, disassembly is the first and most important step.

This article will help you disassemble the Mi 5s Plus without damage, tell you what tools you will need, and warn you of common errors. We will take a detailed look at the process of removing the back cover, turning off the plumes and removing key components. And if you are planning to replace the battery or display, here you will find useful tips for selecting spare parts and checking their health.

Important: disassembling your smartphone takes away your warranty (if it's still valid) and can cause permanent damage if you're not careful. If you're not sure about your abilities, trust the repairs to the professionals.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need. Xiaomi Mi 5s Plus has a metal body with adhesive back mount, so a regular screwdriver will not be enough.

• 🔧 Plastic mediators or shoulder blades (2-3 (S) for a careful sliding of the lid.
• 🔨 Cross screwdriver PH00 — screw-hole.
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic mat or tray – so as not to lose small screws.
• 🔋 Screen suction cup – will help remove the display module (if required).
• 🛠️ Tweezers and antistatic bracelet - for working with boards.

Also, prepare your workspace: it should be well-lit, without dust or static electricity. Put your smartphone on a soft substrate (like a silicone mat) to avoid scratching the case. If you plan to replace the battery, discharge the phone to 20 to 30 percent in advance to minimize the risk of fire in the event of an accidental short circuit.

⚠️ Warning: Do not use metal tools to lid the lid - they leave scratches and can damage antenna lines on the inside of the case. Also avoid overheating with a hairdryer: if the temperature exceeds 100°C, the glue can drier even more.

Step 1: Removing the back cover

The back of the Mi 5s Plus is attached to the glue and the latches around the perimeter, and to remove it, you first need to soften the adhesive layer.

1. Turn off your smartphone and remove the tray for SIM-map.
2. Heat the back cover around the perimeter (especially in the area of the chamber and the lower part) for 2-3 minutes. Keep the hair dryer at a distance of 5-7 cm, so as not to overheat the plastic elements.
3. Insert a plastic mediator into the gap between the lid and the body (start at the bottom corner where the charging connector is located). Carefully drive the mediator along the body, gradually splitting the latches.

If the lid doesn't respond, reheat the problem area. Don't put too much effort into it, it can cause the fingerprint scanner plume to break down, which runs under the lid, and once the latches are snapped, remove the panel and put it aside.

Under the lid, you'll see:

• 🔋 Battery with connector.
• 📱 Motherboard closed with metal screen.
• 📷 Camera plumes and fingerprint scanner.
• 🔊 Dynamics and vibrator.

Step 2: Turn off the battery and remove the metal screen

Before you continue disassembling, be sure to turn off the battery.

1. Put a plastic mediator on the black connector of the battery (located at the top of the battery).
2. Carefully pull it up to disconnect from the motherboard.

Now you can remove the metal screen that protects the board from interference, and it's mounted on 10 PH00 screws (different lengths!) and remember the location of each screw, and you have to screw them into the same places when you build them, otherwise you can damage the board.

After removing the screws, gently tuck the screen on one side and remove it, and underneath it you'll see the motherboard, the plumes, and other components.

⚠️ Warning: Don't touch the contacts on the board with your fingers - static electricity can disable the chips. If you don't have an antistatic bracelet, regularly touch a grounded metal object (for example, a heating battery).

Step 3: Removing the motherboard

The Mi 5s Plus motherboard is mounted on multiple screws and connected to the body by multiple plumes to extract it:

1. Disconnect all the plume connectors (camera, display, buttons, fingerprint scanner) and gently apply a plastic mediator to that.
2. Unscrew all the screws holding the board (usually 6-8 pieces).
3. Put the board on one side and gently lift it up, and if it's not taken out, check if there are any unconnected plumes left.

Be especially careful at this point: the board is connected to the body with thin antenna wires (they are glued to the back cover), if they are torn off, the reception of Wi-Fi and 4G signals will deteriorate.

After the fee is extracted, you will have access to all the key components:

• 📟 Snapdragon 821 processor and RAM.
• 📡 Communication modules (Wi-Fi, Bluetooth, NFC).
• 🔌 Charging connector USB Type-C.
• 🎤 Microphones and speaker.

Step 4: Replace the battery

The battery in the Mi 5s Plus is one of the most vulnerable, and over time, its capacity drops and the phone starts to run out quickly, to replace the battery.

1. Unplug the old battery. It's glued to double-sided tape. Plug it with a plastic mediator and pull it up gently. If the glue is too strong, warm the battery with a hair dryer (no more than 60°C!).
2. Clean the installation site from glue residues with alcohol or acetone.
3. Install a new battery (we recommend the original or from proven manufacturers, for example, ZOP or CAM).
4. Connect the battery connector to the board and check its operation by temporarily assembling the phone.

The cost of a new battery for the Mi 5s Plus is from 800 to 1500 rubles. When buying, pay attention to the capacity (should be at least 3800 mAh) and the availability of protection against overheating.

💡

Before installing a new battery, check its voltage with a multimeter. It should be in the range of 3.7-4.2 V. If the voltage is below 3.5 V, the battery may be malfunctioning.

Step 5: Disassembly of the display module

If you need to change the screen or touchscreen, you need to remove the display module, which is one of the most difficult operations, because the plumes are very fragile.

1. Warm up the front of the phone (especially on the edges of the screen) for 3-4 minutes.
2. Stick the suction cup to the bottom of the display and gently pull it up. Insert a plastic mediator into the slit.
3. Slowly drive the mediator along the body, separating the glue. Take your time - if you pull too much, you can damage the plumes.
4. Once the display is separated, disconnect the touchscreen and display plumes from the motherboard.

In the Mi 5s Plus, the screen and touchscreen are glued together, so it is impossible to replace them separately - only the entire module. The cost of a new display is from 2500 to 4000 rubles.

⚠️ Attention: If you have stripes, broken pixels or a touchscreen that doesn't work after you change the screen, check the density of the plumes. Often the problem is solved by reconnecting. If the defect remains, the new module may fail.

Build the phone: reverse order and check

To assemble Xiaomi Mi 5s Plus you need in reverse order, but with some nuances:

• 🔧 First, connect all the plumes to the motherboard and check their performance (for example, turn on the phone without a lid and check the camera, display, buttons).
• 🔋 Make sure the battery is tightly glued and doesn’t hang around – this can cause contacts to break.
• 📱 When installing a metal screen, do not drag the screws - this can damage the board.
• 🔥 Before the final assembly, warm up the back cover with a hair dryer (this will help the glue better grasp).

After assembly, turn on the phone and check:

• 📶 Network operation (4G, Wi-Fi, calls).
• 🔊 Sound in the speaker and microphone.
• 📷 Cameras (main and front).
• 🔋 Charging and battery indication.
• 👆 Fingerprint scanner.

If everything is working correctly, the disassembly was successful! If there are problems (for example, the touchscreen is not working or there is no sound), disassemble the phone again and check the connection of the plumes.

💡

The key to disassembling is to take your time and follow the order of turning off the plumes, and most breakages in self-repair are due to haste or the use of inappropriate tools.
