Xiaomi Redmi 5 Plus has proven to be a reliable device with excellent value for money, but time goes by and even the most durable gadgets require maintenance. A broken screen, a worn battery or a faulty charging connector are common reasons why owners think about self-repair. Before you start physically interfering with the design, you need to clearly understand that the disassembly process requires accuracy, the right tool and compliance with safety precautions.
Unlike modern models with frameless screens and adhesive structures, the Redmi 5 Plus body is designed in a classic way, which greatly simplifies access to internal components. The main task in dismantling is to preserve the integrity of plumes and plastic mounts, which can burst if handled carelessly. In this guide, we will take a detailed look at each step, from power out to motherboard removal, so that you can perform repairs efficiently and without unnecessary risks.
It's important to understand that any interference with the device can lead to a loss of warranty, if it is still relevant. However, if the smartphone is no longer warranty, and replacing the screen or battery in the service is unreasonably expensive, self-disassembly becomes a rational decision. Proper preparation of the workplace and the availability of good lighting is the key to the successful completion of the operation to "resuscitate" your gadget.
Tools and workplace preparation required
Good disassembly is impossible without the right tools. Using inappropriate items such as kitchen knives or thick needles can damage the case or, worse, puncture the battery. To work with the Redmi 5 Plus, you will need a standard set of mobile repair wizards, which can be purchased from specialized stores or ordered online.
Special attention should be paid to the organization of space. The work surface should be clean, dry and well lit. It is recommended to use an antistatic mat or at least a clean sheet of paper so that small screws do not get lost and rolled under the furniture. Also prepare containers for sorting fasteners, as the screws in the smartphone can have different lengths and threads.
- 🔧 Set of screwdrivers: mandatory presence of cross PH000 and a small-sized flat screwdriver.
- 🛠 Plastic blades (mediators): necessary to snap the latch of the case without damaging the plastic.
- 🌡 Dryer or thermophen: You will need to soften the glue under the display if you plan to replace it.
- 🧲 Magnetic mat or jars: for systematization of screws of different sizes.
☑️ Preparation for disassembly
Keep in mind personal safety. Although the voltage in the smartphone battery is not fatal, short circuiting can cause the lithium polymer battery to heat up and ignite. So never start disassembling if the battery has visible bloating or shell damage.
Primary dismantling: Removal of the back cover and battery
Xiaomi Redmi 5 Plus design assumes that the main available element for the user is only the tray SIM-Unlike older phones with removable batteries, the back cover is mounted on screws and plastic latches. The first step should always be to remove the tray from the car. SIM-cards and memory cards so as not to damage it in further manipulations.
After removing the tray, you need to unscrew the two screws located at the bottom of the case on the sides of the Micro-USB charging connector. These screws are often hidden under decorative plugs or simply noticeable in the recesses. Be careful: do not make excessive efforts to not break the thread in the aluminum frame.
⚠️ Warning: Before starting any work, be sure to completely turn off the smartphone. Attempting to disconnect the plumes under voltage can lead to the combustion of the power controller on the motherboard.
Then comes the most important step of the first disassembly, which is to snap the back cover. Start at the bottom end, carefully inserting a plastic blade or mediator into the gap between the back panel and the frame. As you move along the perimeter, pass all the latches. A characteristic click will signal the successful release of the retainer. Do not use metal objects, as they can leave scratches on the glossy surface or damage the antenna inserts.
Once you remove the lid, you'll see an interior space that's covered by a plastic lining that has speakers and plumes on it, and you'll need to take that lining off to access the battery and the motherboard, and it's held on to a few screws around the perimeter and one in the center, under the Mi logo. Unscrew them, gently lift the lining, and try not to damage the plume of the lower speaker that might be glued to it.
Detailed instructions: disabling plumes and charging
Once the plastic pad is removed, key components are available: the battery, motherboard and main camera module, and precision of movement is crucial at this stage. The Redmi 5 Plus motherboard is secured with multiple screws that must be unscrewed before being removed.
The first thing you do is you turn off the battery plume, and this is a critical step that turns the device off and makes it safe for electronics to go on, and the connector is at the bottom of the board, closer to the center, and you need to tuck the connector carefully, using a plastic blade or nail, avoiding jerks.
Nuances of connector work
Then you detach the plumes of the display module and the touchscreen, which are located next to the battery connector, but have wider contacts. For secure fixation, some connectors can be pressed with a metal bar that also needs to be unscrewed. Once all connections are turned off, you can carefully remove the motherboard from the case.
When removing the board, look for an antenna contact (a golden spring) that connects the board to an antenna located on the back cover or at the end. It must be carefully sidelined so as not to bend or break. Also be careful with the main camera module - it can be attached separately or be part of the overall design with the board, depending on the revision of the device.
| Component | Firming | Features of withdrawal |
|---|---|---|
| Battery | Adhesive tape + plume | Requires heating for safe peeling |
| Maternity fee | Screws + plumes | Antenna contact must be disconnected |
| Display module | Glue + plume | Removed after the frame is removed or together with it |
| Charging charges | Screws + plume | Located at the bottom, access after removal of the cover |
💡
The main rule of disassembly is sequence of actions. Never pull components until you make sure that all screws and plumes are disconnected.
Replacement of the display and touch screen: design features
The Redmi 5 Plus model is used in IPS-This makes it much easier to replace the glass, because you don't have to glue the glass or clean the old glue from the metal frame, but if you buy a frameless module, the process becomes more complicated and requires a special glue. B-7000 analogue.
To replace the framed screen, you first need to completely dismantle the old broken module, it is held on a double-sided tape around the perimeter, heating the back of the screen with a hairdryer to 60-70 degrees will help soften the glue, be careful: do not overheat the matrix, otherwise there may be spots or it will stop working.
Once the old module is removed, you need to carefully clean the body frame of glue and dust residues. Any grain of sand that falls under the new screen will be noticeable and can lead to the appearance of "dead" areas of the touchscreen or cracks during assembly.
- 🧪 Apply a thin layer of glue around the perimeter of a new frame or module.
- 📱 Carefully combine the module with the body, starting from the top.
- 🔩 Press the screen on the edges and fix the rubber bands on 15-20 minutes before drying.
- 🔌 Connect the plumes and check the touchscreen and images before the final assembly.
If you sell a screen without a frame, you'll have to move all the small elements (speaker, button plumes) from the old bezels to the new one, a process that requires jewellery precision and good tweezers, and in most cases it's easier and more reliable to buy a full module assembled, even if it costs a little more.
Work with the battery and lower charge
Battery replacement is one of the most common reasons for smartphone disassembly after several years of use. In Xiaomi Redmi 5 Plus, the battery is located under the motherboard and glued to the body with a powerful double-sided duct tape. It will not be possible to simply “take it out” – it requires heating.
Use a dryer to warm up the back wall of the case in the battery area. The temperature should not exceed 80 degrees so as not to damage the plastic cells. After heating, you can carefully tuck the battery with a plastic card or a spatula, trying not to damage the shell. A puncture of the battery can cause ignition, so act extremely carefully.
⚠️ Warning: If the battery is swelling, do not pierce it or bend it, remove it as carefully as possible using only plastic tools, and immediately dispose of it in a special container.
The bottom board, which houses the Micro-USB charging connector and the main speaker, is screwed to the case. Often charging problems are not related to the board itself, but to contact oxidation or a plume break. Before replacing, try cleaning the connector with alcohol and a soft brush. If this does not help, the board is easily replaced after turning off the plume and twisting the fasteners.
When you install a new battery, make sure that the contact area on the board is clean. Sometimes you need to replace the contact connector on the board if it is unwell, and you need a soldering iron and small electronics skills, which goes beyond just disassembling.
Assembly of the device and verification of functionality
The Redmi 5 Plus is built in reverse order, but it has its own nuances. The main rule is not to close the case completely until the initial check is done. Build the device on weight: connect the plumes of the display, touch screen and battery, then turn on the phone.
Check the basic functions: sensor operation (swipe your finger all over the screen), speaker and headphone sound, camera operation, vibration and charging. If everything works correctly, you can turn off the device and start the final fixation of the components. If there are problems, take it apart again and check the density of the plumes.
When you install the back cover, make sure all the latches fall into place. Start fixing the lid on the top, then press the side faces, and at the end snap the bottom. Twistle the screws at the bottom of the body, but don't pull them over to avoid damaging the thread. SIM-map.
💡
After you build your new battery, the first few charge cycles (0-100%) should be avoided from emptying your phone or leaving it on charge longer than necessary, which will help calibrate your battery controller.
The final step is to clean the case of fingerprints and dust. Now your Xiaomi Redmi 5 Plus is ready for active use again. Self-repair not only saves money, but also gives confidence in the quality of the work performed.
