Xiaomi Redmi 5 Plus is a popular smartphone of 2018, which is still in active use. However, over time, even reliable equipment requires repairs: replacement of the battery, cleaning connectors or diagnosing malfunctions. 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 a step-by-step photo guide, a list of necessary tools and safety tips. We will also tell you what mistakes beginners most often make and how to avoid them. If you have never taken a smartphone apart before, donβt worry: the Redmi 5 Plus has a relatively simple design, and with the right approach, the process will not take much time.
We warn you that self-repair will cancel the manufacturer's warranty, if it is still valid. If you are not confident in your abilities, you should contact the service center.
Preparation for disassembly: tools and security measures
Before you start disassembling, make sure you have everything you need, and without the right tools, you risk damaging the body, the plumes, or even the motherboard.
- π§ Plastic blade (or mediator) - for careful putting of the lid and plumes.
- βοΈ Cross screwdriver (size) PH00 or PH0) β screw-hole.
- π₯ Hair dryer or thermoair station - if the glue is too strong (optional).
- π§² Magnetic mat or container β to avoid losing small screws.
- πΈ Smartphone for photography β capture each step so as not to confuse details during assembly.
Also, prepare your workspace: it should be well-lit, clean and without static electricity. It is best to disassemble your smartphone on a table with an antistatic mat or at least on a smooth surface covered with fabric.
β οΈ Warning: Don't use metal tools to tamper with plastic parts - they leave scratches and can break latches. If you don't have a plastic blade, you can wrap metal insulation.
Before disassembly completely turn off the smartphone and remove SIM-Memory card (if installed) will prevent accidental contact closure and data loss.
Step 1: Removing the back cover
The back cover of the Redmi 5 Plus is mounted on latches and glue, and to remove it, you need to carefully tweak the edge and gradually separate it from the body. Start at the bottom, where the charging sockets and headphones are located, where the glue is usually weaker.
Put a plastic blade in the gap between the lid and the body and slowly lead it along the edge. You will hear the characteristic clicks - this is the latches detached. Don't put too much effort: if the lid does not lend itself, heat it slightly with a hairdryer (temperature not higher than 60 Β° C) to soften the glue.
- πΉ Start with the lower left corner β there is less risk of damage to the plumes.
- πΉ Move counterclockwise, gradually releasing latches.
- πΉ If the lid is raised, but not removed - check if there are no unconnected latches left.
β οΈ Attention: Under the lid are the fingerprint scanner plumes and antenna contacts. Don't pull the lid upwards, raise it to the top first. 1-2 mm and make sure nothing interferes.
When you take the lid off, put it aside, and on the inside, you'll see a battery, a motherboard, and a few plumes, and don't touch the contacts with your bare hands, because static electricity can damage the chips.

Step 2: Battery disconnection
The battery in the Redmi 5 Plus is glued to the body, and removing it is one of the most important steps. Before you disconnect the battery, be sure to disconnect it from the motherboard.
- Find the battery connector β it is located next to the motherboard and marked in black or red.
- Carefully tuck the connector into a plastic spatula and pull it up. Don't use metal tools!
- Make sure the connector contacts are not bent or oxidized.
Once you shut it down, you can start removing the battery, and if it's bloated, don't try to puncture it or bend it, and if it's blown, it's dangerous, it can ignite or explode, and you'd better go to the service.
To remove the battery:
- Tap the edge of the battery with a plastic spatula.
- If it does not lend itself, slightly heat the body with a hairdryer (not higher than 60 Β° C).
- Put a thin plastic card or spatula under the battery and slowly separate it from the glue.
Be careful, because there are plumes and antenna contacts under the battery, and don't pull the battery too hard, because it could damage it.

Step 3: Removing the motherboard
The motherboard is the most expensive and fragile component of the smartphone, and before you take it out, you have to disconnect all the plumes and connectors. Redmi 5 Plus has several of them:
| plume/connector | Location. | How to disconnect |
|---|---|---|
| Display plume | Top of the pay | Push the black fixator and carefully pull out |
| Camera plume | Upper left corner | Open the metal latch |
| The fingerprint scanner plume | The bottom of the fee | Plastic spatula |
| Charging connector | Lower right corner | Unscrew 2 screws and remove the module |
Once all the plumes are disconnected, unscrew the motherboard-mounting screws. Redmi 5 Plus typically has 8-10 of them. Remember or photograph the location of each screw - they may vary in length!
When all the screws are unscrewed, gently raise the margin charge. If it doesn't lend itself, check if there are any unconnected plumes or hidden screws under the stickers. Don't force - the board may crack.

If you're afraid of damaging the plumes, put paint tape on them before removing the board, which will help to fix them in the correct position and avoid clamps.
Step 4: Disassemble the front panel and display
If you need to replace the display, charger or speaker, you have to remove the front panel. In the Redmi 5 Plus, the screen is glued to the body, and it requires special care to remove it.
- Heat the edges of the screen with a hair dryer (50-60Β°C) for 2-3 minutes. This will soften the glue.
- Insert a plastic blade into the gap between the screen and the case and slowly lead it along the edge.
- When the screen rises, donβt remove it completely β first disconnect the display plume from the motherboard.
Underneath the screen are the sensor plume and the display plume, which are easy to damage, so act carefully. If the screen is cracked, use tape to fix the fragments and avoid cuts.
After removing the screen, you will have access to:
- π Dynamics and microphone
- π Headphone jack.
- π Charging connector.
- π· Front camera.
β οΈ Attention: If the screen stops working after disassembly, check the integrity of the plumes. Often the problem lies in damaged contacts or incorrect connection. Do not turn on the smartphone with the screen removed - this can lead to a circuit.
Step 5: Replace frequently failing parts
The following components are most often broken in Redmi 5 Plus:
- π Battery - Loses capacity through 2-3 Signs: quick discharge, shut down when 20-30% charge.
- π΅ Charging connector -- oxidized or loosened. Signs: phone not charging, cable falling out.
- π The speaker and the microphone are clogged with dust. Signs: quiet sound, distortion, the interlocutor does not hear.
- π· Main camera -- falls out of order. Signs: blurry photos, artifacts, no focus.
If you're replacing a battery, choose an original battery or a quality battery (such as a ZMI or a Baseus battery), cheap batteries can swell or lose capacity quickly.
- Make sure the contacts are clean (wipe with alcohol if necessary).
- Make sure the plume is not clamped.
- Stick the battery to a double-sided tape or special glue.
To replace the charging connector will require a soldering station. If you do not have experience soldering, it is better to contact the service - improper soldering can damage the motherboard.

The most common mistakes when replacing the battery: the use of non-original batteries, improper connection of the plume and insufficient fixation with glue, which leads to rapid failure or even fire!
Smartphone Builder: How to Avoid Mistakes
Building the Redmi 5 Plus after repair is as important as disassembling, and here are the key points to consider:
- π§ Screw them into the same holes you screwed them out of. Tangled screws can damage the board.
- π± Trains β make sure they are properly connected and fixed by latches.
- π Battery β make sure it is tightly glued and doesnβt hang around.
- π§Ή Cleanliness β Remove dust and debris from internal surfaces before assembly.
Don't rush to turn on your smartphone after assembly.
- Make sure all screws are twisted.
- Make sure the cover fits tightly to the body.
- Connect the charger and check if charging is underway.
- Turn on your phone and test all the features: camera, speaker, sensor, fingerprint scanner.
If something doesnβt work after assembly (for example, the sensor doesnβt react or the screen doesnβt turn on), take the smartphone apart again and check:
- All the plumes are connected.
- Won't they get a cable out somewhere?
- Are there any foreign objects (screws, pieces of plastic) left inside?
