How to disassemble the Xiaomi Mi phone: instructions for beginners with photos and videos

Disassembling the Xiaomi Mi smartphone is a challenge that every owner sooner or later faces: whether it is replacing the battery, repairing the screen or cleaning from dust. However, the wrong approach can lead to damage to the plumes, chipping on the body or even completely failing the device. In this article, we will understand how to disassemble any Xiaomi Mi model (from Mi 5 to Mi 11) with minimal risks, what tools you need and what to look for when working with specific series.

It is important to understand that the design of Xiaomi smartphones has evolved: while in the early models (Mi 3, Mi 4) the rear cover was removed relatively easily, in the new ones (Mi 10, Mi 11) glue and complex latches are used, we will tell you how to adapt the process to your model, and also give tips for safe disassembly without specialized equipment.

Before you start, answer three questions: 1. Do you have any experience with small electronics? 2. Are you prepared to have the warranty (if it still works) cancelled? 3. Are you sure the problem is with hardware, not with software?

If at least one question the answer is “no” – it is better to contact the service center.

Preparation for disassembly: tools and safety

The first rule of successful disassembly is the right tools, and without them, you risk damaging the body, the plumes, or even the chips.

• 🔧 Plastic mediators or shoulder blades (2-3 - for gently putting the lid on, leave the metal tools for extreme cases!
• 🔨 Screwdriver cross (PH00 or PH0) — for screws in most Xiaomi Mi models.
• 🧲 Magnetic mat or container - so as not to lose small screws (in Mi 9 and newer there can be up to 15 pieces!).
• 🔥 Dryer or thermal air station - for softening the adhesive in models with waterproof housing (Mi 10 Pro, Mi 11 Ultra).
• 📸 Smartphone for photography – fix the location of plumes and screws at each stage.

If you're disassembling a model older than the Mi 8, you can do without a hair dryer, the lid is attached to the latches. But for the Mi 10 and newer, be sure to warm up the body around the perimeter to 60-70.°C, otherwise the glue will not stop and you will tear the battery plume.

⚠️ Warning: Do not use a household hair dryer at maximum power! hot air flow should be uniform and directed at the edges of the case, not the screen or camera. OLED-matrix.

Also prepare the workplace: • Work on a flat, clean surface (preferably on an antistatic mat). • Turn off the phone and remove SIM-map + Discharge the battery to 20-30% – this will reduce the risk of fire in case of accidental circuit.

Step-by-step disassembly: from the cover to the motherboard

The disassembly process can be divided into 5 stages, and we will describe the universal algorithm, and we will put the nuances for specific models in a separate table below.

Step 1: Removal of the back cover

Start by warming up the case (if the model is glue-free). Keep the hair dryer at a distance of 5-7 cm and drive along the edges for 2-3 minutes.

1. Insert a plastic mediator into the gap between the lid and the case (usually start at the bottom edge where the charging connector).
2. Carefully drive the mediator along the perimeter, alternately snapping the clamps. In the Mi 9 and newer models, the latch can be up to 20 pieces!
3. Do not apply force - if the lid does not lend itself, warm up again.

In the Xiaomi Mi 5 and Mi 6, the lid is aluminum and mounted on screws under plugs. They must first be removed (for example, with a needle), and then twist the screws.

Step 2: Battery shutdown

Once the lid is removed, first of all, unplug the battery plume.

1. Find the battery connector on the motherboard (usually black or orange).
2. Put a plastic blade on the side, not on top, so as not to damage the contacts.
3. Insulate the connector with tape so that you do not accidentally close the fee during further disassembly.

⚠️ Warning: If you're understanding the Xiaomi Mi 10 Ultra or Mi 11 Pro, be careful - it uses a dual battery (two cells connected in parallel!

Stage 3: Removing the motherboard

The motherboard in Xiaomi Mi is mounted on screws and can be protected by a metal screen.

1. Untwisted all the screws (they can be of different lengths - remember where you were!).
2. Disconnect the plumes: display, cameras, on/volume buttons, speaker.
3. Carefully tuck the board from one edge and lift it. Don't pull around corners, there may be fragile elements (such as an antenna connector).

In the Mi 8 Explorer Edition and Mi 9 Transparent Edition, the board can be glued to the body – a hairdryer will help again.

Step 4: Dismantling the screen (if necessary)

If the purpose of disassembly is to replace the display, act as follows:

1. Warm up the screen around the perimeter (especially in models with a AMOLED — glue is very sticky).
2. Substrate the display module with a plastic spatula, starting at the top edge (where the speaker and front camera are located).
3. Disconnect the display and sensor plume (they can be combined into one connector or separated).

In Xiaomi Mi Mix and Mi Mix 2, the screen is glued especially strongly - you may need a special suction cup and thread for cutting glue.

Stage 5: Disassembly of additional modules

If you need to get to the camera, speaker or vibrator:

• 📷 Camera: usually mounted on 2-3 screws and a plume. In the Mi 10 Pro and Mi 11 Ultra, the camera module is massive - be careful with its weight.
• 🔊 Dynamic: Can be glued or fixed to latches. In stereo speakers (Mi 9 and later), there are two of them: the bottom and the top.
• 📳 Vibromotor: in models up to Mi 8 it is round, in new - linear (long strip.

Nuances of disassembly for popular models Xiaomi Mi

Xiaomi’s smartphone design varies greatly depending on the year of release and series, and the table below shows the key disassembly features for the most common models:

For Mi models 10T mi 11T (With a plastic case, the adhesive is less aggressive and the cover is flexible, but the Mi 11 Ultra with a ceramic back panel requires special care: if the hair dryer is overheated, the ceramics can crack!

💡

If you are looking at Xiaomi Mi with IP53 (Splash protection, after assembly, check the tightness by immersion in water for 10 seconds (no power!). If bubbles appear, repeat the pasting.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes when disassembling Xiaomi Mi. Here are the most common of them and ways to prevent them:

• 🔋 Forgetting to turn off the battery. Consequences: short circuit, burnt circuit board. Always first thing is to disconnect the battery plume!
• 🔧 The screws get confused. In the Mi 9 and later, the screws are of different lengths, if you mix them up, you can damage the board. Solution: spread them out in the containers with the signatures.
• 📱 Pulling by the plumes. The display plumes and the cameras are fragile. Right: pull the connector up, not the plume itself.
• 🔥 The hair dryer at maximum can melt plastic clamps or damage the body. OLED-Optimal temperature: 60-70°C.
• 🧹 They ignore the dust. When disassembling, the dust can get into the camera or the speaker. Solution: use an antistatic brush or a compressed air balloon.

Another common problem is damage to flexible printed circuit boards (FPC). For example, in the Xiaomi Mi 10, the fingerprint scanner plume goes under the battery. If you touch it, the scanner will stop working. Always check the disassembly circuit specifically for your model!

⚠️ Attention: In models with LPDDR5 In memory (Mi 11 and later), the motherboard can be multi-layered, and if you don't pull it out, you run the risk of tearing it apart, which is not refurbishable!

💡

If you’re disassembling the Xiaomi Mi for the first time, work out on a broken phone or watch a video disassembly of your model specifically – this will reduce the risk of errors by 80%.

Build the phone after disassembly: a step-by-step algorithm

It is often harder to assemble a phone than to disassemble it, and here are the key points to avoid problems:

1. Check all plumes: they must be clean, free of clatters and tightly inserted into connectors. In the Mi 10 and newer plumes, the plumes may have protective covers - remember to close them!
2. Apply a new glue: If you completely removed the lid, the old glue has lost its properties. Use B-7000 or special glue for smartphones.
3. Tighten the screws cross-to-cross: this will prevent skewing boards. In the Mi 11, first twist the corner screws, then the center screws.
4. Warm up the glue before the final assembly: if the lid does not fit tightly, warm it up with a hair dryer (50-60).°C) and press for 2-3 minutes.

Don't turn on the phone right away after assembly.

1. Connect the charging and check if the current is coming (the charging indicator should appear).
2. If everything is fine, turn on the device and check: 📶 Network operation (SIM-map, Wi-Fi). 🔊 Sound in speakers and microphone. 📷 Cameras (main and front). 🔋 Battery Charging (Percentage must be displayed correctly).

If the phone does not turn on after assembly, check: • Connect the battery plume (possibly the contact has gone away). • Correct installation of the power button (in Mi 9 and later it can block the turn on when the assembly is incorrect). • Integrity of the display plume (if the screen does not glow, but the phone vibrates when the buttons are pressed).

When the Disassembly Will Not Help: Alternative Solutions

Sometimes the problem that caused you to disassemble your phone can be solved without opening the case.

• 🔄 Phone glitching or braking: try resetting to factory settings (in Settings) → The phone. → Resetting. In 60 percent of cases, software lags solve this.
• 🔋 Battery goes down quickly: check the charge consumption by applications in Settings → The battery, maybe the background software, not the battery itself, is to blame.
• 📵 Sensor not working: If the screen is touch-responsive but delayed, try calibrating the sensor through the engineering menu (#4636##).
• 🔊 Missing sound: clean the headphone jack (in the Mi 8 and older it often clogs) or check the settings → Sound. → Sound quality.

If you suspect a hardware problem (for example, the phone does not turn on after a fall), but are not confident in their abilities, use the diagnostic codes:

#4636## - information about the battery and network
##0*## - Screen (Color) Test
#06# – IMEI check (if the phone is on but not catching the network)

In Xiaomi Mi models with Qualcomm Snapdragon (most lines) you can run hardware diagnostics in Fastboot mode:

1. Turn off the phone.
2. Press Volume Down + Power before the Fastboot logo appears.
3. Connect to the PC and enter the command: fastboot devices If the device is determined, then the problem is not in the motherboard.

Where to buy spare parts for Xiaomi Mi and how not to run into a fake

If the disassembly was successful, but the part still needs to be replaced, it is important to choose a quality part.

• 🛒 Xiaomi official service centers: sell original parts, but prices are 30-50% higher than the market.
• 🌍 AliExpress, eBay: Look for sellers with a rating above 98% and reviews of a specific part.For example, for the Mi 11, the original battery must be labeled with a label. BM4X.
• 🏬 Local parts stores: ask for a certificate of quality. In Russia, verified suppliers are MobiPart, GSMMoscow.

What to look for when buying:

For Xiaomi Mi 10 and newer models, be careful with fake batteries - they may not support fast charging or even swell after a month of use.

• 🏷️ Serial number sticker and QR-code.
• ⚖️ Weight corresponding to the original (for example, for Mi 11 - about 50 grams).
• 🔌 Support for the declared charging power (checked through Aida64).

💡

Before buying a part, check its compatibility by model number (printed on a sticker under the lid). For example, the battery for the Mi 10 (model) M2001J2E) It is not suitable for Mi 10 Pro (M2001J2G).
