How to disassemble a smartphone Redmi (design from Xiaomi) without damage: instructions with photos and videos

Xiaomi-branded Redmi smartphones are known for their value for money, but even they are not immune to breakdowns. Disassembly may be required to replace the battery, repair the display, clean up the dust or recover from a fall. However, improper dismantling often results in damage to plumes, cracks in the case or loss of warranty. In this guide, we will learn how to disassemble Redmis of different series — from the budget Redmi A to the flagship Redmi Note Pro — with minimal risks.

It's important to understand that Xiaomi's smartphone design has evolved, and if the back cover was relatively easy to remove in older models (before 2019), it's glued to the frame in new models, and the battery is often fixed with adhesives. We'll look at the universal steps and nuances for specific lines, and we'll also list the tools you need. If you've never disassembled your gadgets, you'd better go to a service center, especially if the device is warranty.

What tools will be needed to disassemble Redmi

Without the right tools, it's almost impossible to disassemble Redmi, and the risk of damage to the body or plumes increases significantly.

• 🔧 Plastic mediators or shoulder blades (2-3 pieces) - for careful putting of the cover and disconnection of the plumes.
• 🔨 The screwdriver. PH00 or PH0 — Most of the screws in Redmi have a small cruciform slitz.
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic mat or organizer – so as not to lose screws and small details.
• 📱 Suction cup for screens - will help remove the display module (relevant for models with OLED-screen).
• 🧴 Isopropyl alcohol (90%+) — cleaner.

For models with a waterproof body (for example, Redmi Note 12 Pro+) will additionally require a special glue for sealing after assembly. If you are planning to replace the battery, buy a double-sided tape or glue kit in advance - the original Xiaomi adhesive is disposable.

⚠️ Warning: Do not use metal blades or knives, they scratch the body and can close the board. If there is no plastic mediator at hand, a guitar mediator or credit card will do (but with caution!).

Preparation for disassembly: what to do before dismantling

Before you take up the screwdriver, follow a few critical steps:

1. Turn off your smartphone and remove it. SIM-card with memory card (if any).
2. Discharge the battery to 20-30% – this will reduce the risk of fire in case of accidental circuit.
3. Back up your data via Settings → About Phone → Backup or Mi Cloud.
4. Take a picture of the location of the screws and plumes – this will simplify the reverse assembly.

If you’re disassembling a Redmi with a non-removable battery (most models after 2018), consider that when the battery is disconnected, the smartphone will completely turn off, and all unsaved data will be lost. We also recommend working on an anti-static mat or at least grounding yourself (for example, touching a metal object) to avoid static discharge, which can damage the motherboard.

Step-by-step: how to remove the back cover of Redmi

The most important step is to separate the back cover, and depending on the Redmi model, the process may vary:

Models with clips (Redmi 4X, Redmi 5A, Redmi 6/6A, etc.)

Old smartphones have a lid on plastic clips to take it off.

1. Insert the plastic mediator into the gap between the lid and the frame (start at the bottom corner where the charging connector is).
2. Carefully drive the mediator along the body, snapping clips around the perimeter.
3. Lift the lid - it should separate without resistance.

Models with adhesive attachment (Redmi Note 8/9/10/11/12, Redmi K-series)

In new devices, the cover is glued, so you will need heating:

1. Heat the back of the smartphone with a hair dryer (keep it at a distance of 5-7 cm, a temperature of 60-80 ° C) for 2-3 minutes.
2. Try to cover with a sucker or a mediator, and if you don't, warm up again.
3. As soon as the lid begins to move away, slowly lead the mediator around the perimeter, separating the glue.

Critical: Do not overheat your smartphone above 80°C. This can damage the battery or OLED-If the glue is too strong, use disassembly threads (sold in smartphone repair kits).

💡

If the lid doesn't lend itself, don't force it -- you better dry the problem area again, and sudden movements can break the fingerprint scanner plume or the antenna contacts.

Disconnection of the battery and plumes: what not to do

Once you remove the lid, you'll see the battery and a few plumes connecting the board to the display, cameras and buttons. First of all, always turn off the battery, which will prevent short circuits from further disassembly. Most Redmi batteries are connected via a connector on the motherboard:

1. Find a black or orange connector with the inscription BATTERY or BATT.
2. Make sure you put a plastic blade (not metal!).
3. Make sure that the contacts are not closed – you can check with a multimeter.

Then disconnect the other plumes:

Display plume (usually wide, with a latch).

- The fingerprint scanner plume (thin, brittle).

- Camera plumes (can be glued, disconnect carefully).

⚠️ Note: If you are looking for Redmi with AMOLED-screen (e.g. Redmi) K60), Do not touch the metal parts with a screwdriver - static electricity can damage the matrix. Use an antistatic bracelet or periodically ground.

In some models (such as the Redmi Note 12 Pro+), the battery is glued to the body to remove it:

1. Put the battery on the side with a plastic spatula.
2. If it doesn't lend itself, gently pull the black pen-ribbon (if any) or use isopropyl alcohol to dissolve the glue.
3. Do not bend the battery and do not prick it - the risk of fire!

Disassembly of the motherboard and other components

If you need to get to the motherboard (for example, to replace the charging connector or microphone), after disconnecting the battery and plumes:

1. Turn out all the screws that lock the board. Redmi often uses screws of different lengths — remember where it was.
2. Carefully tuck the board with a plastic spatula. It can be glued to the body with a thermal paste.
3. Disconnect the remaining plumes (speakers, vibratory motor, antenna cables).

In liquid-cooled models like the Redmi K60 Ultra, there's a heat tube under the board, so don't rot or damage it, because it can overheat the processor.

- Charging nest (fragile contacts).

Microphone and speakers (can be glued).

- Antenna contacts (thin metal tracks).

If you're disassembling Redmi to replace the Type-C connector, note that newer models often solder it to the board, which requires a soldering station and microelectronics experience, and it's easier for beginners to replace the entire plume with the connector (if it's removable).

💡

The motherboard is the most expensive component of a smartphone, and if you're not sure about your skills, you'd better stop at replacing the battery or display and leave the board repaired to the professionals.

Redmi assembly after disassembly: how to avoid mistakes

Building a smartphone is often harder than disassembling it.

• 🔄 Check all the plumes - they should fit tightly into the connectors (you will hear a click).
• 🔩 Twisting the screws cross-cross to avoid skewing the fee.
• 🔋 Stick the battery to a new two-way Scotch (original Xiaomi glue loses properties after dismantling).
• 📶 Check the antenna contacts – they should fit tightly to the frame.

After assembly:

1. Connect the charging and make sure the smartphone is turned on.
2. Check the operation of the touch screen, cameras, speakers and fingerprint scanner.
3. If something doesn’t work, disassemble the device again and check the connection of the plumes.

For models with a waterproof body (for example, Redmi Note 12 Pro+), after assembly, apply the sealant on the joints of the cover and frame. Without this, the water and dust protection (IP53/IP68) will be violated.

⚠️ Note: If after assembly the smartphone does not turn on, but when connecting charging the indicator is lit - the problem may be in the power button (shute or micro-switch.

Frequent Redmi Disassembly Mistakes and How to Avoid Them

Even the most experienced craftsmen make mistakes sometimes, and here are the most common ones:

Another common problem is that the flexible power button plume is damaged, and in Redmi, it often goes along with the fingerprint scanner, and if you're not tidy, you can break the contacts, and if you're assembling the power button, but the smartphone is switched on from charging, the problem is the plume.

In models with an infrared port (for example, Redmi Note 11) be careful with its plume – it is thin and easily breaks. If after disassembly the remote control stopped working, check the connection of this module.
