The decision to disassemble a smartphone is usually made when the device is critically damaged or requires replacement of failed components. Xiaomi Mi 5 Plus (also known as Mi 5s Plus) has a rather complex internal architecture, where many elements are hidden under metal screens and tightly fitting plumes. Inexperienced users may think that the process of disassembly will irreversibly damage the gadget, but with the right tools and patience, this procedure can be performed at home.
The main difficulty with this device is the location of the fingerprint scanner on the back, which is connected to the motherboard with a long and vulnerable plume. Any careless movement when removing the lid can lead to a break in this connection, which will require complex soldering or replacement of the entire unit, which is why it is important to strictly observe the sequence of actions and not apply excessive physical force where it is not intended by the design.
Before you start work, you need to evaluate your skills and prepare the workplace. B-7000 glue or similar adhesive is a must to seal the case after assembly, as factory adhesive tape always loses its properties when opened. If you have never faced mobile electronics repairs before, it is recommended to carefully study each stage to minimize the risks of damage to the motherboard or display module.
⚠️ Warning: Before starting any work, be sure to turn off your smartphone and remove the tray SIM-Attempting to disassemble the switched-on device may short-circuit and cause the power controller to fail.
Tools and workplace preparation required
Quality workplace preparation is the key to successful repair and preservation of the integrity of all small screws and parts. To disassemble the Xiaomi Mi 5s Plus, you will need a specific set of tools that you can not always find in a standard home medicine cabinet. Lack of the right screwdriver can lead to slicing of the screw faces, which will make further disassembly almost impossible without drilling the fastener.
Special attention should be paid to the heating elements, since the display module in this model is glued around the perimeter. The use of open lights, such as a lighter, is strictly prohibited, as this can damage the matrix or melt plastic frame elements.
- 🔧 Precision screwdrivers (cross-haired) PH000, flat, torx T5) — squirt.
- 🌡️ Thermophen or heating platform – to soften the glue under the screen and back cover.
- 🎴 Plastic blades and mediators - for safe snapping of latches without damage to the housing.
- 💳 Suction or suction holder - for careful lifting of the display or back panel.
- 🧴 Clay. B-7000 or bilateral tape - for the final sealing of the body.
Organize the space so that all the parts are at hand and the light falls evenly, without creating glare on the screen. It is recommended to use a magnetic mat or a sorting tank for screws, signing each stage of dismantling. This will help to avoid a situation where after assembly there are unnecessary parts or the body does not converge due to improperly screwed screws of different lengths.
☑️ Preparation for disassembly
Rear cover removal and shutdown of plumes
The process of opening the case Xiaomi Mi 5 Plus begins with the separation of the rear panel, which is made of metal and is attached to the glue around the perimeter. Heat the edges of the device evenly, paying special attention to the angles where the glue concentration is usually higher. Do not try to remove the cover immediately after heating, let the material warm up, otherwise the metal can deform when applied force.
Insert the suction cup into the bottom of the back cover, closer to the logo, and gently pull upwards, creating a small gap. Insert a plastic blade or a thin mediator into the resulting gap and lead the tool along the side faces, gradually cutting the glue layer. The movements should be progressive and not too deep, so as not to damage the plume of the fingerprint scanner, which is immediately under the lid.
⚠️ Warning: Do not open the back cover sharply and completely! first make sure the fingerprint sensor plume is disconnected or has a sufficient length reserve, otherwise it will break instantly.
When you remove the lid, you'll have access to the top of the battery and connectors, and the first thing you need to do is turn off the battery to turn off the system, and then you need to carefully bend the protective metal plate that covers the connectors, and disconnect the battery plume with a flat blade, and then you can safely turn off the display and touchscreen plumes.
- 🔋 Disconnect the battery plume from the motherboard.
- 🖥️ Remove the metal protective brace from the display connectors.
- 🔌 Disconnect the plume of the main camera module and touch screen.
- 🆔 Carefully unplug the fingerprint scanner plume from the inside of the cover.
Remember or write down where each fastener was twisted. Using a screw too long in the hole for a short one can cause the board to break down and the smartphone to fail.
Removal of the display module and frames
The display module in Xiaomi Mi 5s Plus is glued to a metal frame, and its replacement often requires a complete dismantling of the insides or neat unplugging of the matrix. If your goal is to replace the screen itself, then after turning off the plumes, you need to continue disassembling the main part of the device.
To remove the frame, you have to twist all the visible screws around the ends of the device, and then you have to heat up again, because the glue under the display is very strong. Use a suction cup to create tension, and a thin line or a special string of pass through the adhesive under the screen, moving the tool from side to side, and this process requires maximum concentration, because the matrix is very fragile.
Risks of screen removal
If you plan to change only the glass (touchscreen), the process becomes even more time-consuming, requiring separation of the glass and matrix on a special machine, which is almost impossible to do at home without damaging the polarization layer or the matrix itself, so most often the module is replaced in the assembly.
| Component | Type of attachment | Difficulty withdrawal | Risk of damage |
|---|---|---|---|
| Back cover. | Glue + latches | Low. | Medium (FPC plume) |
| Battery | Adhesive tape | Medium | High (puncture) |
| Display. | Perimeter glue | Tall. | critical |
| Maternity fee | Screws + plumes | Medium | Medium. |
Replacement of the battery and work with the battery
One of the most common reasons for disassembling the Xiaomi Mi 5 Plus is the wear of the battery. Over time, the capacity of the Li-Ion cell drops, and the phone stops holding charge. In this model, the battery is located under a metal protective plate and is tightly glued to the body with double-sided tape.
To remove the battery, you must first remove the metal plate, which can be further fixed with glue. Carefully heat the battery area with a hairdryer, but do not overheat it so as not to cause bloating or fire.
- 🔥 Heat the bottom of the case to soften the glue under the battery.
- 🏗️ Remove the metal protective plate over the battery.
- 🧩 Carefully tuck the edge of the battery and slowly disconnect it from the body.
- 🧹 Clean the seat of old glue before installing a new battery.
When installing a new battery, make sure the connector sits tightly and until you click. Don't bend the battery control plume at a sharp angle, as this can damage the current tracks. After connecting, check the voltage on the contacts with a multimeter if possible to make sure that the new battery is working.
💡
Remains of old adhesive from the case are best removed with isopropyl alcohol and plastic card. Do not use metal objects so as not to damage the antenna inserts.
Assembly of the device and verification of functionality
The Xiaomi Mi 5s Plus is assembled in reverse disassembly order, but requires even more care. Before you twist the screws and stick the covers, you need to conduct an initial check of the health of all systems.
Check the touchscreen, the speaker response, the vibrator and, most importantly, the camera module and the fingerprint scanner. If all functions are working correctly, you can proceed to the final fixation. Put a thin layer of B-7000 glue on the frame, spread it evenly and press the screen.
⚠️ Warning: Don't put too much glue on, because excess glue can squeeze out and damage electronics or lock buttons.
After applying the glue and installing the components, the device must be fixed with rubber harnesses or a load for 1-2 hours until the adhesive is completely dry. Only after complete polymerization of the adhesive can the phone be turned on and active operation begin, this will provide the necessary tightness and protection from dust.
Frequent errors and expert recommendations
When self-repairing, users often make mistakes that can cost a device life. One of the most common problems is damage to the plumes when you carelessly handle the tool. The plumes in the Xiaomi Mi 5s Plus are very thin and sensitive to the hall, so you need to work with them exclusively with plastic tools.
Another mistake is ignoring the heat when you take the screen off. Trying to pull the display "cold" is almost guaranteed to cause a crack in the glass or rupture of the matrix. Patience and proper temperature are key success factors. Also, remember static electricity, which can kill chips.
- 🚫 Do not use metal blades to tweak the screen or cover.
- 🌡️ Do not overheat the device, keep the temperature within 80-90 degree.
- 🔋 Do not try to remove the swelled battery without eye and hand protection.
- 🧼 Degrease surfaces before applying new glue for better adhesion.
If you find that the screw is not spinning or the part is not amenable, do not use force. You probably missed the hidden screw or the glue is not warm enough. Recheck the instructions and evaluate the situation again. The right approach will keep your smartphone functional and prolong its life.
