Disassembling Xiaomi is a challenge that owners face when replacing a battery, repairing a display or cleaning from dust. However, improper removal of the back panel can damage plumes, cracks in glass or loss of leakage. In this article, we will discuss all the current ways to open the case for different Xiaomi, Redmi and POCO series, including models with adhesive mounting and classic latches.
It is important to consider that the design of Xiaomi smartphones has changed over the years: if the Redmi Note 4X (2017) was removed without tools, the Xiaomi 13 Pro (2023) uses a combination of glue and latches, as well as protection from moisture IP53. We will describe in detail what tools you need, how to avoid typical errors and what to do if the panel does not respond.
Preparation for the review: tools and security measures
Before you start removing the back panel, make sure you have everything you need.
- 🔧 Plastic mediators (2-3 Pc.) - for careful putting of the cover without scratches.
- 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
- 🧲 Suction - helps create an initial effort to separate the panel.
- ⚡ Screwdriver. T3/T4 — for the purpose of removing the screws (if any).
- 📏 Plastic card or spatula - an alternative to the mediator.
If you are working with a model with a degree of protection IP53/IP68 (for example, Xiaomi 12T pro POCO F5 Pro, note that after the disassembly, the leakage will be broken, B-7000). Also, it is necessary:
- 🔋 Turn off your smartphone and remove it. SIM-map + memory card (if any).
- 📱 Remove the cover and protective film – they may interfere with the.
- 🕒 Plan enough time – haste leads to breakdowns.
⚠️ Warning: Do not use metal tools (knives, screwdrivers) to lick the lid - they leave scratches on the aluminum frame and can damage the plumes under the panel. AMOLED-screens (e.g. Redmi) K50) The display plume is often located close to the edge of the body.
Ways to open the back panel: from latches to glue
The method of parsing depends on the type of mounting of the lid. Xiaomi smartphones use three main options:
- Classic latches (old models: Redmi 4A, Mi A1) - the lid is kept on plastic clips, removed without heating.
- Glue + latches (most modern models: Redmi Note 10 Pro, POCO X3 Pro) - requires heating the glue.
- Full gluing (flagships: Xiaomi 13 Ultra, Mix Fold 3) is a complex analysis with the risk of damage.
Below are detailed instructions for each case.
Models with latches (no glue)
Suitable for: Redmi 3S/4/4A, Mi A1/A2, POCO M2/M3.
Turn off the power and remove the tray. SIM-map|
Insert a plastic mediator into the gap between the lid and the frame (start at the bottom corner)|
Carefully drive the mediator around the perimeter, clicking clips |
When resisting, do not push harder - check if all latches are released-->
If the lid is not supplanting, check to see if the clips in the USB-C area of the connector or the volume buttons remain uncut. In POCO M3 models, an additional latch near the camera module is often found.
2. Models with glue + latches
The most common variant (e.g. Redmi Note 9/10/11, Xiaomi 11 Lite) requires heating:
- Warm up the hair dryer around the perimeter (keep at a distance of 5-7 cm, the temperature is 70-80 ° C).
- Suction create an initial force in the lower part of the body.
- Insert the mediator into the resulting gap and slowly lead along the edge.
- If the glue is too strong, repeat the heating.
⚠️ Attention: In models with NFC-antennae (e.g, POCO F3) It's often glued to the inside of the lid, and if you unscrupulously remove it, you can rip off the antenna plume, and that's going to lead to a non-working contactless payment.
3.Full-cleaning flagships
For the Xiaomi 12/13 series, Mix Fold or Black Shark, you will need:
- 🔥 Heating to 80-90°C (but not higher to avoid damaging the battery!).
- 🧴 Use of isopropyl alcohol (70%+) glue-dissolving.
- 🛠️ Special devices (e.g. iFixit Opening Picks).
These models often have two-layer glue, the first layer around the perimeter, the second layer under the battery, and if you're not sure about your skills, you should go to a service center.
What to do if the panel cracked when removed?
Table: Analysis methods for popular Xiaomi models
| Model | Type of attachment | Tools | Difficulty (1-5) | Features |
|---|---|---|---|---|
| Redmi Note 8/9/10 | Glue + latches | Fryer, mediator, sucker. | 3 | NFC-antenna on the lid, be careful with the battery plume |
| POCO X3/X3 Pro | Glue + latches | Fen, mediator, alcohol | 4 | A thick layer of glue, requires strong heating |
| Xiaomi 11T/12T | Complete gluing | Hazel, alcohol, professional shoulder blades | 5 | Glass back panel, high risk of cracking |
| Redmi 4A/5A | Latches | Mediator. | 1 | Removable battery, no glue. |
| Black Shark 4/5 | Glue + screws | T4 screwdriver, hairdryer, mediator | 4 | Screws under the lid, be careful with the cooler |
Common Mistakes and How to Avoid Them
Even experienced craftsmen sometimes make mistakes when parsing Xiaomi.
- 🔥 Overheating of the body - if you hold the hair dryer too close, you can melt plastic clips or damage the battery. Optimal temperature is 70-80°C, heating time - 1-2 minutes.
- ⚡ Sharp separation of the cover - this leads to a break of plumes (especially in models with a NFC Or wireless charging. Move the mediator smoothly, without jerking.
- 🛠️ Using inappropriate tools – metal screwdrivers scratch the frame, and too thick mediators break the latches.
- 📱 Ignoring screws – in some models (for example, Black Shark) there are screws under the lid that need to be unscrewed before being completely removed.
In Xiaomi models with liquid cooling system (for example, Xiaomi 12S Ultra), if you do not carefully parse, you can damage the heat pipes, which will lead to overheating of the processor. If after assembly the smartphone began to warm up a lot, check the integrity of the thermal paste and tubes.
💡
Before assembly, clean the inside of the lid and the body of glue residues with isopropyl alcohol, which will improve adhesion when re-silting and prevent dust from entering the inside.
What to do after the panel is successfully opened?
When the lid is removed, you'll see the inside of the smartphone, and here's what you can do.
- 🔋 Battery replacement – in most Xiaomi models, the battery is glued, a plastic spatula and isopropyl alcohol will be required to remove it.
- 📸 Cleaning the camera – dust on the camera module degrades the quality of the photo. Use a soft brush or a spray of compressed air.
- 🔊 Replacement of the speaker or microphone in models POCO Redmi speakers are often attached to latches.
- 🔄 Thermopaste update is relevant for gaming smartphones (Black Shark, POCO F4 GT).
If your goal is to replace the display, consider that in models with a AMOLED-The plume is very fragile, and if it is damaged, it will lead to artifacts on the screen or complete inoperability of the display.
⚠️ Note: In Xiaomi smartphones with Always-On Display (for example, Xiaomi 12 Pro) when the battery is turned off, the screen settings may be lost.
💡
Before assembly, make sure all plumes are tightly connected and the screws are twisted with the right force. Tight screws can damage the board, and weakly twisted ones can lead to backlash of components.
How to assemble the smartphone back: step-by-step instructions
The assembly is often more difficult to parse. Follow this algorithm.
- Make sure all components (battery, cameras, speakers) are connected correctly.
- If you remove the battery, glue it to a new layer of glue (for example, 3M 9448A).
- Make sure that NFC-The antenna (if any) is not dented and lies flat.
- Apply a thin layer of sealant glue (B-7000) around the perimeter of the case to restore dust protection.
- Carefully press the back panel, starting at the top (where the cameras are located).
- Twirl the screws (if any) with a force of 0.3-0.5 N·m (use a dynamometer screwdriver).
After assembly:
- 🔌 Connect the charger and check if charging is going on.
- 📶 Make sure all antennas (Wi-Fi) are working, NFC, mobile).
- 🔊 Test the speakers and microphone (record voice message).
If after the assembly of the smartphone does not turn on, check:
- Connecting the battery (possibly the plume has gone).
- Integrity of the power button (in POCO models it is often attached to a separate plume).
- Short circuit (if the board concerns metal parts of the body).
