Disassembly Xiaomi Redmi 5: detailed instructions with nuances and warnings

Xiaomi Redmi 5 (codenamed rosy) remains a popular device even years after its release, because its reliability and maintainability attract users. However, disassembling this device has its own characteristics: a fragile battery plume, adhesive fixation of the rear cover and the risk of damage to flexible cables if you are planning to replace the battery, screen or speaker, it is important to know the right sequence of actions so as not to turn the repair into an expensive error.

In this article, we will take Redmi 5’s disassembly process by step, from tool preparation to back-assembly, and learn what key points beginners often miss (such as why you can’t pull the lid off the corner), how to avoid plumes breaking, and what to do if the screws don’t unscrew, and we’ll also provide unique data on the location of hidden latches that are missing from standard instructions.

Warning: disassembling a smartphone is warranty-free (if it is still valid) and can lead to malfunctions if you do not take the right actions. If you are not sure about your skills, contact the service center. For experienced users, below is the most detailed guide with photos and tips from the masters.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need.Redmi 5's minimum disassembly toolkit:

• 🔧 Plastic blade (or mediator) - for putting the lid and plumes.
• ⚙️ The screwdriver (PH00 or PH0) — hull-rotor.
• 🔥 Hair dryer or thermoair station - for softening the glue (optional, but recommended).
• 🧲 Magnetic mat or container – so as not to lose screws.
• 📸 Smartphone for shooting – fix the location of the parts before dismantling.

Also, prepare your workspace: clean, well-lit, and without static electricity; put soft cloth on the table (like a microfiber) to avoid scratching the body; if you're disassembling your phone for the first time, practice on an unnecessary device or watch video disassembly, this will help avoid typical mistakes.

⚠️ Warning: Do not use metal blades or knives – they will damage plastic latches and can close contacts on the board. Also do not apply excessive force when grazing the lid: the glue on the Redmi 5 holds tight, but it can be weakened by heating to 60-70°C.

If you are planning to replace the battery, pre-order an original or high-quality analog battery with a capacity of at least 3300 mAh (like the original). Cheap fakes may swell or not hold the charge. To verify the authenticity of the battery, check the label: the original is labeled Xiaomi or BYD with a serial number.

Step 1: Removing the back cover - how not to break the latches

The most important step is to dismantle the back panel, and on Redmi 5, it's attached to glue and plastic latches that are easy to break.

1. Turn off the phone and remove the tray for SIM-cards (use a paper clip or special key).
2. Heat the edge of the lid with a hair dryer around the perimeter for 1-2 minutes. The temperature is no higher than 70 ° C, so as not to damage the display.
3. Insert the plastic blade into the gap between the lid and the frame (start at the bottom edge where the charging connector is located).
4. Carefully drive the blade along the body, gradually snapping the mounts.

Redmi 5 has 3 hidden latches: two on the sides of the camera and one on the top (under the antenna lines) that are easy to miss, which will lead to a crack in the lid. If you feel resistance, warm up the problem area again.

Is the phone off the grid?

Is the tray removed? SIM-map?

Are the edges of the lid heated with a hair dryer?

Is the plastic spatula ready?

Is there a place for propellers?

-->

When you take the lid off, you'll see the battery, the motherboard, and the plumes. Don't pull the plumes! They're fragile and can come off the board. If the lid doesn't respond, don't use force, you'd better repeat the heat or use a special suction cup (sold in phone repair kits).

⚠️ Note: Some Redmi 5 versions (such as the global version) may have an extra protective film under the lid. Don't confuse it with glue - it needs to be carefully removed to get to the screws.

Step 2: Shutting down the battery – why it’s critical

Before you touch the board or plumes, be sure to turn off the battery. This will prevent short circuits and damage to components. On Redmi 5, the battery connector is located at the bottom of the board and closed with black insulation tape.

Procedure:

1. Remove the insulating tape from the battery connector (it can be glued - put it with a spatula).
2. Carefully slap the battery plume with a plastic spatula and unplug it from the board. Don't use metal tools!
3. Check with a multimeter that there is no voltage on the board contacts (optional, but recommended for safety).

If the plume doesn't move, don't pull it -- it's probably glued. Warm the socket with a hairdryer (60°C maximum) and try again. Never pull the plume off by force, which can rip the contact pads off the board, and you'll need a soldering station to repair it.

After the battery is turned off, lock the plume with tape to the case so that it does not interfere with further disassembly.

Step 3: Dismantling the motherboard and plumes

The Redmi 5 motherboard is mounted on 11 screws of varying lengths, and remember their location, because when you build them, the screws have to fall into place, or you can damage the board or the body, and we recommend taking a picture of them or putting them on a magnetic mat in order.

Once you unscrew the screws, you can gently raise the board with a spatula. It can stick to a heat-conducting paste -- don't pull it, but sway it slowly from side to side. Notice the plumes.

• 📱 The display plume is the most fragile, fastened by a latch.
• 🔊 Dynamic plume - often glued, disconnect gently.
• 📶 Antenna cables are thin, do not overflex them.

If the board fails, check if all screws are unscrewed (sometimes one screw is hidden under the sticker). Also make sure all plumes are disconnected - forced retrieval of the board can tear the connectors.

💡

If the screw doesn't unscrew, don't use force, try putting WD-40 or alcohol on it. Wait 5 minutes and try again. If the thread is broken, the screw can be drilled with a thin drill (0.8 mm) or pulled out with tweezers.

Step 4: Replacing the battery – nuances and errors

The Redmi 5 battery is glued to the body with double-sided tape, and it will require:

1. Disconnect the battery plume (as described above).
2. Put a plastic blade on the battery on either side, and if it doesn't lend itself, warm up the body with a hair dryer (maximum 60°C).
3. Carefully pull on a special black tape (pull-tab), which is glued to the battery. If there is no tape, use a spatula, but do not pierce the battery!

When installing a new battery:

• 🔋 Check that the contacts match the connector on the board.
• 🧴 Apply a new bilateral scotch (for example, 3M 9448A) fixative.
• ⚡ Do not turn on the phone immediately after replacement - let the battery "get used to" for 10-15 minutes.

Common mistakes in replacement:

• 🚫 Use of metal tools → Risk of battery puncture and fire.
• 🚫 Sticking the battery to superglue → Then it's impossible to take it off.
• 🚫 Connecting the battery plume to the board with the phone on → short-circuit.

1. Is the battery plume connected correctly?

2. whether there is damage to the contact board.

3. whether the voltage of the new battery corresponds to the original (3.8-4.4V).

Often the problem lies in oxidized contacts - they can be cleaned with alcohol and eraser.-->

Step 5: Disassemble the screen and replace the display

Replacing the display with a Redmi 5 is more difficult than replacing the battery, because the screen is glued to the frame and connected with a fragile plume. If you have a cracked glass, but the matrix is intact, you can only replace the glass (but this requires special equipment).

1. Removal of the back cover (as in step 1).
2. Shutting off the battery (step 2).
3. Unscrewing screws fixing the metal frame of the screen (there are 4 pieces).
4. Heating the display with a hairdryer around the perimeter (temperature 70-80 ° C) to soften the glue.
5. Screening plastic blade, starting from the lower edge (where the connector of the plume).

Important: The display plume on Redmi 5 consists of two parts:

- Main plume (goes to the motherboard).

Sensor plume (thin, often glued to the frame).

When disconnecting, be extremely careful - the sensory plume breaks even with a small effort.

If you are replacing only the glass, not the entire module, you will need to:

- Special separation knife for glue cut.

UV glue (e.g., LOCA) for bonding new glass to a matrix.

- Vacuum pump for removal of air bubbles.

This procedure is best entrusted to professionals, as if you make an error, you can damage the matrix.

⚠️ Attention: On Redmi 5, the screen is connected to the frame not only with glue, but also with two hidden latches in the upper corners. If you don't snap them, the glass can crack when you remove them. To get to the latches, carefully press them through a napkin.

Phone Assembly: How to Avoid Mistakes

The Redmi 5 should be assembled in reverse order, but with nuances in mind:

1. Make sure all the plumes are tightly connected (the snap of the latch should be heard).
2. Check if there are any extra screws left - everyone should be in their place.
3. When installing the battery, do not overflex the plume and do not press it with screws.
4. Close the lid, starting at the top, and gently snap all the clamps.

After assembly:

• 🔌 Connect the charger and check if charging is going (the indicator should catch fire).
• 📱 Turn on your phone and test all the features: sensor, speaker, microphone, cameras.
• 🔋 If the battery is new, calibrate: completely discharge and charge the phone 2-3 times.

Typical problems after assembly and their solution:

If you have any extra screws or parts left after you've assembled, don't turn on your phone! Go back to the disassembly and find what you forgot to install. Most often, small washers under the screws or insulation pads are lost.
