Disassembly Xiaomi Redmi Note 5: a complete guide with photos and tips

Xiaomi Redmi Note 5 is one of the most popular smartphones in the budget segment, released in 2018. Despite the years since, the device is still actively used due to balanced performance and reliable design. However, over time, even such a device can require repairs: from replacing the battery to cleaning the connectors or recovering from a fall. Disassembling the Redmi Note 5 yourself is a task that is feasible, but requires accuracy and knowledge of nuances.

In this article, we will take a closer look at the process of disassembling a smartphone, point out key points that beginners often miss, and give advice on how to choose tools. It is important to understand that doing the wrong thing can cause plumes to damage, detach the display, or even the motherboard to fail. So if you have never taken your smartphone apart, carefully study each step before you start.

Preparation for disassembly: tools and security measures

Before you start disassembling the Xiaomi Redmi Note 5, make sure you have everything you need. Not even one tool can complicate the process or cause breakdown. Here is the minimum set you'll need:

• 🔧 Plastic blades (2-3 (a) - for the careful smearing of the hull and the disconnection of the plumes.
• ⚙️ Set of screwdrivers (cross-haul) PH00, flat 1.5 mm) for screws of different sizes.
• 🔥 Dryer or thermoair station – to soften the glue under the display (if you need to change the screen).
• 🧲 Magnetic mat or container – to avoid losing small screws.
• 📱 Suction cups (2 pcs) - for removing the display (optional, but simplifies the process).
• 🔌 Tweezers – for working with small details, for example, plumes.

Also, prepare your workspace: it should be well lit, clean and free of static electricity (ideally an antistatic mat). If you're taking your smartphone apart for the first time, take a picture of each step on your phone, which will help you get the device back together properly.

⚠️ Warning: Do not use metal blades or knives to tweak the case! They can damage plastic latches or plumes. Also avoid excessive heat of the display with a hairdryer - temperatures above 80°C can damage the matrix.

Step 1: Removing the back cover

The first step is to separate the back cover from the body, and in the Redmi Note 5, it's mounted on plastic latches and a little glue, so you don't break the mounts, you have to be careful.

1. Turn off your smartphone and remove the tray for SIM-map.
2. Heat the edges of the back cover with a hair dryer (temperature 60-70 ° C) for 1-2 minutes - this will soften the glue.
3. Insert the plastic blade into the gap between the lid and the body (start with the lower right corner where the charging connector is located).
4. Carefully drive the shoulder blade along the perimeter, alternately snapping the clamps.

If the lid doesn't work, warm up the problem area again. The main thing is to take your time. When all the latches are disconnected, remove the lid and put it aside.

Warm up with a hair dryer longer (up to 3 minutes) |

Try another angle (e.g. upper left) |

Use the second blade for uniform pressure |

Check to see if there are any unclogged clamps left.-->

Under the lid, you'll see the battery, the motherboard and a few plumes. In the Redmi Note 5, the fingerprint scanner plume is glued to the lid -- be careful not to tear it when you're removing it. If you're planning to replace the battery, the next step is to disconnect the battery.

Step 2: Disconnect the battery and remove the motherboard

Before any internal component work, be sure to turn off the battery, which will prevent short circuits and protect the board from damage. In the Redmi Note 5, the battery connector is located at the top of the device under the protective film.

Algorithm of action:

1. Remove the protective film from the battery connector (it is usually black or yellow).
2. With a plastic spatula, gently slap the connector and unplug it from the board.
3. If the battery is swelling, don't try to puncture it or bend it. Better replace it with a new one.

After the power is cut, you can start removing the motherboard.

1. Unscrew all the screws that fasten the board (usually 8-10, of different sizes - remember where it was!).
2. Disconnect all the plumes: display, cameras, speaker and buttons. To do this, raise the locks of the connectors upwards (they are white or black).
3. Carefully slap the board with a spatula and remove it. Don't pull around the corners, there are fragile elements in there!

⚠️ Attention: In the Redmi Note 5, the display plume is very thin and easily torn. If you feel resistance when disconnected, check if all the locks are raised.

Step 3: Replace the battery (if required)

The battery in the Redmi Note 5 is one of the most vulnerable parts, and after 2-3 years of use, it loses up to 30-40% of its capacity, and in some cases it starts to swell, and replacing the battery is one of the most common reasons for disassembling a smartphone.

To replace, follow the following steps:

1. After turning off the battery connector, warm it up with a dryer (temperature 70-80 ° C) for 2-3 minutes. This will soften the glue.
2. Put a plastic blade on the battery from any angle and pull it up gently. Don't use metal tools!
3. If the battery is glued strongly, put a thin plastic card or a special pulling tape under it (attached to some battery sets).
4. Install the new battery, pre-removal of the protective film with the adhesive side, press it evenly throughout the area.

When choosing a new battery, pay attention to capacity: the original battery in the Redmi Note 5 has a capacity of 4000 mAh. Buy only certified parts - cheap analogues can quickly fail or even ignite.

💡

If the new battery does not hold charge after replacement, check if the connector is properly connected and if you damaged the battery plume during installation.

Step 4: Display Display Disassembly and Screen Replacement

Replacing the display in the Redmi Note 5 is a more difficult task than replacing the battery, and it's important not only to remove the glass carefully, but also to not damage the plume that goes from the matrix to the motherboard. If the screen cracks, but the image is displayed, most likely only the touchpad is damaged. If the image is missing, the problem is in the matrix or the plume.

Procedure:

1. Warm up the display with a hair dryer around the perimeter (80°C) for 3-5 minutes. This will soften the glue.
2. Hold the suction cups on the screen (if any) and pull up. If the glass doesn't lend itself, gently put a plastic spatula on it.
3. When a slit appears, insert a plastic card or mediator into it and slowly lead along the edge, separating the display from the case.
4. Disconnect the display plume from the motherboard (don’t forget to raise the connector lock!).

When installing a new display, make sure it is compatible with your model. The Redmi Note 5 uses a 2160×1080 matrix with a 5.99 diagonal. Also make sure that the plume is not twisted or squeezed - this can lead to vertical bars on the screen.

Step 5: Cleaning connectors and recovering from moisture

If the smartphone stopped charging, it does not see SIM-If you have a map or a sensor that's bugging, it could be that the connector is contaminated or the contacts are oxidized after they get moisture, and if you take it apart, it can bring the device back to life.

To clean the connectors:

• 🧹 Use isopropyl alcohol (90% or higher) and a soft brush. Do not use water or household cleaners!
• 🔌 Carefully clean the charging connector, contacts SIM-Pay attention to places with visible oxides (green or white coating).
• 🔥 After cleaning, allow the board to dry completely (at least 1 hour.

If your smartphone has been in water, disassemble it as quickly as possible and rinse the board with distilled water (it doesn’t contain any impurities that cause corrosion). After that, dry the device in rice or silica gel for 24-48 hours. Don’t turn on the smartphone until you make sure it’s completely dry!

⚠️ Warning: If the board shows signs of corrosion (green or white divorces), it is likely that professional repairs will be required.

Step 6: Build a smartphone and check the health

The Redmi Note 5 should be built in reverse order, and here are some key points to consider:

• 🔩 Make sure all screws are swirled into their places. Rotors of different lengths - if you mix them up, you can damage the board.
• 📶 Check that all the plumes are connected correctly, and the connector locks are omitted.
• 🔋 When installing the battery, do not overflex it - this can lead to internal ruptures.
• 🔧 Press the back cover evenly, starting from the corners. If it does not sit tightly, check if the plumes or latches interfere.

After assembly, turn on the smartphone and check:

• 🔋 Charging (plug the cable and make sure the current is going on).
• 📶 Work. SIM-maps and nets.
• 🎵 Sound in the speaker and microphone.
• 📷 Cameras (front and main).
• 👆 Sensor and fingerprint scanner.

If something doesn't work, take your smartphone apart again and check the problem node, and most often, errors are caused by improperly connected plumes or compressed cables.

💡

If the phone doesn't turn on after assembly, check the battery and power plume connection. In 80% of cases, the problem lies there.
