How to open the smartphone Xiaomi Redmi: detailed instructions with photos and tips

Disassembling the Xiaomi Redmi is a challenge that owners face when replacing a battery, repairing a screen or cleaning from dust. However, improper opening of the case can damage the plumes, lose leakage or even break the device. In this article, we will learn how to safely open any Redmi model — from the budget Redmi Note to the flagship Redmi K — what tools you need and what to look for before you start working.

It's important to understand that modern Xiaomi smartphones are built using glue and latches, not screws (as in the old models), which complicates the process, but makes it possible even at home. The main thing is to follow a clear algorithm and take your time. If you've never disassembled gadgets before, we recommend you first practice on a non-functional device or watch video instructions for your particular model.

In the article you will find:

• 🔧 List of necessary tools and where to buy them
• 📱 Step-by-step instructions for different Redmi series (including Note 12, K60, A2+)
• ⚠️ Common Mistakes and How to Avoid Them
• 🔄 Tips for reverse assembly and performance check

1.Preparation: security tools and measures

Before you open the Xiaomi Redmi, make sure you have everything you need. Not even one tool can damage the case or internal components.

• 🔨 Plastic mediators (or guitar mediators) – to separate latches
• 🔧 Pentalobe screwdriver P2 (For screws in some models, for example, Redmi Note 8 Pro)
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C)
• 🧲 Suction cups (optional, for models with glass back panel)
• 📦 Container for screws - so as not to lose small details
• 🧴 Isopropyl alcohol 90%+ — glue-cleaner

If you are looking at a model with a degree of protection IP53 (For example, the Redmi Note 12 Pro+), be prepared for the fact that the adhesive will be more durable, and the sealing pad may break. In this case, we recommend you to order a new adhesive tape for the case in advance - it can be found on AliExpress or in specialized spare parts stores for Xiaomi.

⚠️ Warning: Do not use metal tools (knives, screwdrivers) to lid the lid! This is almost guaranteed to result in scratches on the body or damage to the battery plume.

Also before the start of the work:

1. Turn off your smartphone and remove it. SIM-map + memory card (if any).
2. Discharge the battery to 20-30% – this will reduce the risk of fire in case of accidental circuit.
3. Make a backup of the data (in case something goes wrong).

2. Features of disassembly of different series Redmi

The design of Xiaomi Redmi smartphones varies depending on the series and year of release. Below we have discussed the key differences that will affect the opening process.

For example, in the Redmi Note 10 Pro, the back cover is attached to glue and latches, but underneath it are screws that hold the metal frame, and if you don't unscrew them before you try to remove the lid, you risk tearing the camera plumes or the battery. 9A It can be disassembled in just 2 minutes - there are only plastic latches without screws.

If you are not sure about your Redmi model, check it by number in the settings: → The phone. → Model. Or Google a search for "Redmi teardown" and you'll find video demos with precise nuances.

3. Step-by-step instruction: how to open the back cover

Now, to the process itself, here's a generic guide that's suitable for most Redmi models, if your device has specific features (e.g., Redmi). K60 with a glass panel, we will point to them separately.

Step 1. Warming up the hull

Use a dryer at minimum power (or a thermal air station with a temperature of 60-80).°C) Warm up the edges of the back cover for 1-2 minutes, moving the hair dryer evenly. This will soften the glue and make it easier to uncouple. Don't overheat! Temperature above 90°C can damage the battery or screen.

Step 2: Filting the lid

Insert the plastic mediator into the gap between the back cover and the frame (start at the bottom edge where the charging connector is located). Carefully drive the mediator along the body, disconnecting the latches. If the lid does not respond, warm up again.

For models with glass panels (K40/K50): Use a suction cup to evenly pull the lid up, while simultaneously poking up the mediator.

Step 3: Disconnect the plumes

Once the lid is removed, you will see the battery and some plumes (fingerprint scanner, camera, speaker). Don't pull the plumes! First unscrew the screws holding the metal plates (if any), then gently disconnect the connectors with a mediator or tweezers.

💡

If the plume is stuck to the connector, don't use force. Put some isopropyl alcohol on the contacts, it will help to remove it safely.

Step 4: Remove the battery (if necessary)

The battery in Redmi is glued to the body to remove it.

1. Tap the battery with a plastic spatula (start at the edge where there are no components).
2. If the glue is too strong, warm up the battery with a hairdryer (max. 60).°C!).
3. Do not use metal tools – the risk of a battery puncture!

⚠️ Warning: If you see a bloated battery (lid raised, screen "going away"), do not try to remove it yourself - it is dangerous.

4.Typical mistakes and how to avoid them

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi Redmi, and here are the most common ones and ways to prevent them:

• 🔋 Battery plume damage occurs when you pull the lid too sharply. Solution: warm up the glue longer and use multiple mediators at once.
• 📱 Scratches on glass panels — metal tools or sand under the lid can scratch the surface. Solution: clean the workplace and use only plastic.
• 🔌 Charging contacts break - the power plume in the Redmi Note is often glued to the lid. Solution: Before removing the lid, check if the plume is reaching for it.
• 🔧 Loss of screws in some models (for example, K60) Solution: put them in order or take pictures of the location.

Another common problem is damage to the sealed gasket in models with protection. IP53. If you plan to collect the phone back, buy a new gasket (costs 100-300 rubles) in advance.

If after the assembly of the smartphone does not turn on, check:

• Is the battery plug connected (sometimes it falls out of the connector).
• Are the contacts closed on the motherboard (look for foreign objects).
• Is the charging connector damaged (try charging through wireless charging if supported).

💡

If the touchscreen doesn't work after disassembly or the screen flashes, the display plume has probably gone away. Carefully plug it back in and check for fixation.

5. Reverse Assembly: nuances and verification

Build Xiaomi Redmi after a showdown is sometimes harder than disassembling, and here are the key points to look out for:

1.Glue and sealing

If you've taken off the battery or the back cover, make sure to replace the glue.

• Double-sided scotch 3M 9448A (battery-powered)
• Adhesive tape for the body (for example, Tesa 61395)
• Sealer for gaskets (for models with IP53)

Stick the tape evenly, without bubbles - this will prevent dust and moisture from entering.

Procedure for connecting the plumes

First, plug in:

1. Battery plume (otherwise the phone will not turn on to check the rest).
2. The display plume (if disconnected).
3. The rest of the plumes (camera, fingerprint scanner, speaker).

After connecting each plume, check its operability (for example, turn on the phone and check the sensor, camera, etc.).

3. Rotary screw twisting

The screws in Redmi are often of different lengths, for example, in the Redmi Note 11 Pro there are:

• Short screws for mounting the cover
• Long screws for a metal frame
• Screws with thread for fastening the motherboard

If you confuse them, you can damage the board or the case. If in doubt, check the photo taken before disassembly.

4. Post-assembly check

After full assembly:

• Turn on your phone and check the sensor, camera, speakers.
• Connect the charger and make sure that the charge is going.
• Check the work of the fingerprint scanner and Face ID (if).
• Make sure there are no backlashes in the case (this is a sign of an improperly installed cover).

⚠️ Warning: If the phone overheats or discharges quickly after assembly, it is likely that the battery is not connected correctly or the plume is damaged.

6. when it is better to contact the service center

Despite the fact that the dismantling of Xiaomi Redmi is possible at home, there are situations when it is better to trust the professionals:

• 🔋 Battery swollen or deformed - the risk of fire when self-extracting.
• 📱 The screen broke and shards of glass hit the inside of the case.
• 🔌 After disassembly, the phone does not turn on and you can not find the cause.
• 💧 The device has been in water (even if it dries later) - you need to clean and replace the gaskets.
• 🛠️ You need to replace the chip or solder components on the board (for example, a charging connector).

The cost of dismantling in the service center varies from 500 to 2000 rubles depending on the model and complexity of the work.

• Replace the battery in the Redmi Note 10 — ~1000 rubles (with spare parts).
• Disassembly and diagnostics of Redmi K50 — ~1500 rubles.
• Replacement of the screen in Redmi A2 — ~2500 rubles (with display).

If you decide to use the service, choose official Xiaomi centers or proven workshops with good reviews. Avoid "garage" repairs - they often use non-original parts that can fail in a few months.

💡

Before visiting the service center take a photo IMEI Your phone (on the box or in the About settings) will help avoid switching your device.

7. Alternative ways to access the insides of Redmi

If you need to access the internal components of Xiaomi Redmi, but you do not want to take the risk and disassemble the case, consider alternative options:

1. Use of magnetic covers

Some models (e.g. Redmi) 9T) have a removable plastic panel to access the SIM-But it's more of an exception, because in most modern Redmis, the cap is non-removable.

2. Contactless diagnosis

If the purpose of disassembly is diagnostics (for example, checking the battery or sensors), try:

• 📊 Programs like AccuBattery to analyze battery status).
• 🔍 Test codes (e.g. #4636## for system information).
• 🖥️ Connecting to the PC through ADB deep-diagnostic.

3. External accessories

For some tasks, you do not need to open the phone:

• 🔌 Wireless charging (if the charging connector breaks).
• 🎧 Bluetooth headphones (if the audio connector is not working).
• 📸 External camera (connected to the USB-C).

If you can’t do without disassembly, but you are afraid to damage the device, consider buying a used phone for training. Avito or Yule often sell non-working Redmis for 500-1500 rubles - ideal for training before working with the main gadget.
