Why does Xiaomi’s disassembly require a special approach?
Xiaomi smartphones are some of the most popular in the world, but disassembly is often a headache for users. Unlike Samsung or iPhone, where the case can be opened with a single screwdriver, Redmi, POCO and Mi devices require accuracy and special tools, due to adhesive joints, fragile plumes and non-standard screws, which are easy to damage if handled carelessly.
In this article, you will find step-by-step instructions tailored to the specifics of the different models, a list of tools you need, and unique tips for undamaged disassembly — such as how to safely disconnect the battery without breaking the plumes — and we will also look at common errors that cause a display or motherboard to break, and give recommendations for reverse assembly.
If you've never disassembled a smartphone, you'd better practice on an old device or go to a service center, but if you decide to do it yourself, follow our instructions carefully.
What tools will you need to disassemble Xiaomi?
Without the right tools, it’s almost impossible to disassemble Xiaomi. Here’s the minimum set you’ll need:
- 🔧 Set of screwdrivers (cross-cross-haul) PH00, PH0, flat 1.5 Mm, five-point Torx. T3/T4 for some).
- 🧲 Suction cup for display removal (diameter 5-7 cm).
- 📏 Plastic mediators or guitar mediators (0.2–0.5 mm thick).
- 🔥 Hair dryer or thermo-air station (for softening glue).
- 🧴 Isopropyl alcohol 90%+ (cleaner).
- 📦 Container for screws (so as not to lose small parts).
For models with a waterproof body (for example, Xiaomi 13 Pro or Redmi Note 12 Pro+) additionally require:
- 🔨 Special glue (e.g. Tesa 61395 or 3M 9448A) reverse-assembly.
- 🛠️ Ultrasonic bath (optional, for cleaning connectors from corrosion).
⚠️ Warning: Do not use metal blades or knives to tweak the body! this is almost guaranteed to result in scratches on the frame or damage to the plumes.
Preparation for the disassembly: what should be done before the beginning?
Before you take up the screwdriver, follow a few critical steps:
- Turn off your smartphone and remove it. SIM-map + memory card (if any).
- Discharge the battery to 20-30% – this will reduce the risk of fire in case of accidental circuit.
- Back up your data (via Mi Cloud or Google Drive).
- Take a picture of the initial state of the case and connectors - this will help with the reverse assembly.
If you're disassembling a battery replacement or display, pre-order original parts. For Xiaomi, this is especially important: non-original batteries can swell or malfunction with a fast-charging system.

Step-by-step: how to disassemble Xiaomi without damage
The disassembly process can be divided into 4 stages. We will consider a universal algorithm suitable for most models (Redmi Note 10/11/12, POCO F3/F4, Mi 11 Lite, etc.). For flagships (Xiaomi 13 Ultra, Mix Fold) may require additional steps.
Step 1: Removal of the back cover
Most Xiaomi smartphones have a glue back cover to remove:
- Heat the edge of the body with a hair dryer (temperature ~60-70 ° C) for 2-3 minutes.
- Suction pick up the lid near the charging connector and gently pull up.
- Insert a plastic mediator into the resulting gap and slowly lead them around the perimeter, separating the glue.
Step 2: Battery shutdown
This is the most dangerous step! Never touch the motherboard until you turn off the battery.
- Unscrew the screws that fix the metal plate of the battery (usually 4-6 pieces).
- Carefully tuck the battery plume and disconnect it with plastic tweezers.
- Check with a multimeter that the voltage on the contact board is 0 V.

Stage 3: Removing the motherboard
The key here is not to break the camera and display plumes.
- Unscrew all the screws on the board (they can be of different lengths - remember where it was!).
- Disconnect all the plumes, starting with the top (camera, speaker) and ending with the bottom (display, Home button).
- Carefully raise the charge, starting at the edge opposite the charging connector.
Step 4: Disassembly of the display (if required)
Xiaomi's display is glued to a frame.
- Heat the screen with a hair dryer (temperature ~50°C).
- Put a plastic shoulder blade on the display, starting at the corner.
- Disconnect the display plume and the fingerprint counting sensor (if any).
| Xiaomi model | Features of disassembly | Difficulty (1-5) |
|---|---|---|
| Redmi Note 10/11 | Sticky back cover, battery on 5 screws | 3 |
| POCO F3/F4 | Metal frame, brittle camera plumes | 4 |
| Mi 11 Ultra | Additional IP53 adhesive protection, complex display module | 5 |
| Redmi 9A/9C | Simple design, removable battery | 2 |
💡
If the screws don't unscrew, don't force! They're likely to have different threads (e.g., the POCO X3 Pro uses reverse- threaded screws on the camera). Check the markings on the screw head or disassembly scheme for your model.
Common Mistakes in Xiaomi Disassembly and How to Avoid Them
Even experienced craftsmen sometimes make mistakes that lead to costly repairs.
- 🔋 Battery plume damage occurs when you disconnect sloppy. Always use plastic tweezers!
- 📱 Scratches on the display -- they appear when you poke the screen with metal tools. Use only plastic mediators.
- 🔧 Loss of screws – Xiaomi often uses screws of different lengths. Store them in a container with cells.
- 💧 Getting moisture on the board - if you clean the case with alcohol, let it dry completely before assembly.
Another common problem is that you don't build correctly, for example, if you forget to plug in the fingerprint sensor plume, the smartphone will turn on, but the scanner won't work. Always check the photos you took before you disassemble.
⚠️ Note: In Xiaomi models with AMOLED-screens (e.g. Mi 11 or POCO F4) The plume is extremely fragile, and if it's damaged, the screen will flicker or fail completely. If you're not sure about your skills, you should contact the service.
How to assemble Xiaomi after disassembly: tips and nuances
Building is often more difficult than disassembling, and here are the key points to consider:
- Check all the plumes - they should be tightly connected, without distortion.
- Apply new glue to the back cover (if it was glue). For waterproof models, use a special sealant.
- Tighten the screws cross-cross to avoid skewing the board.
- Check the operation of all modules before the final assembly: camera, speakers, sensors.
If after assembly the smartphone does not turn on:
- Check the battery connection and charging connector.
- Make sure that no plumes are closed to the body.
- Connect to charging for 10-15 minutes – sometimes it takes time to initialize.
💡
If the touchscreen doesn't work after assembly, the vibration or the camera is probably the problem with the plumes, so take the device apart and check the connection.
When is Xiaomi’s disassembly inappropriate?
It's not always worth it to do self-repair, but here are some of the best times to get in touch with the service:
- 💥 Smartphone fell into the water – corrosion on the board requires professional cleaning.
- 🔥 Damaged motherboard (for example, after a short circuit).
- 📉 Model over 5 years old – parts can cost more than the device itself.
- 🛡️ Device for warranty - self-disassembly cancels it.
It is also worth considering that some models (for example, Xiaomi Mix Fold or Black Shark) have a unique design, and their disassembly without experience is fraught with breakage of hinges or flexible screens.
If you're in doubt, consider the cost of repairs and risks, for example, replacing a battery in a service will cost between 1,500 and 3,000 dollars. ₽, A self-replacement error can result in a 10,000-dollar repair.+ ₽.
