How to disassemble a Xiaomi device: from a smartphone to a smart watch

Disassembling Xiaomi devices is a challenge that owners face when replacing a battery, repairing a screen or cleaning from dust. But without preparation, this process can lead to damage to plumes, loss of warranty or complete failure of the gadget. In this article, we will learn how to properly open the case of a smartphone, smart watch or fitness bracelet from Xiaomi, what tools you will need, and what to look for to avoid typical mistakes.

It’s important to understand that the design of the brand’s devices varies depending on the model and year of release. For example, the flagships of the Xiaomi 13 series have a more complex mounting system than the budget Redmi Note, and the Mi Watch smartwatch requires a special approach due to the miniature details. We will consider the universal principles and nuances for different categories of equipment, as well as give recommendations for the choice of tools and safety.

Preparation for disassembly: tools and precautions

Before you start opening the case, make sure you have everything you need. Not even one tool can damage plastic latches or plumes. Here is the minimum set that most Xiaomi devices will need:

• 🔧 Plastic blades (2-3 Metal tools are not recommended for use, as they scratch the surface and can damage the internal elements.
• 🔨 A screwdriver with a set of bits (cross, star, triving) - for twisting screws. Xiaomi often has screws like this. Y00 or T3.
• 🧲 A magnetic mat or a container to keep the small parts from being lost, and the screws and latches in Xiaomi's devices are miniature and easily lost.
• 🔥 Hair dryer or thermal air station - for softening the glue (relevant for smartphones with adhesive attachment of the back cover, for example, POCO F5).
• 📸 Smartphone for photography – fix each stage of disassembly, so as not to confuse the order of assembly.

Also, prepare your workspace: it should be clean, well-lit, and without static electricity (ideally an antistatic mat). If you're disassembling your smartphone, make sure to remove it. SIM-a card and memory card before starting work – this will save them from damage and data loss.

⚠️ Note: Disassembly of the device will void the Xiaomi warranty if it is still valid. Before opening, check the warranty status in the Mi Account app or on the manufacturer's website. For gadgets older than 2 years (for example, Redmi). 9A 2020) is irrelevant.

Step-by-step instructions: how to disassemble a Xiaomi smartphone

Xiaomi smartphones (including the sub-brands Redmi and POCO) have a similar design, but there are nuances depending on the model.

1. Turn off the device and wait for it to cool completely (if it's heated). SIM-paper-card.
2. Heat the back cover with a hair dryer (~60°C) around the perimeter for 2-3 minutes. This will soften the glue. Don't overheat - the plastic can deform!
3. Put a plastic blade on the lid, starting at the bottom edge (near the USB-C connector). If the lid doesn't lend itself, warm up again.
4. Carefully remove the lid as you move around. Some models (such as the Xiaomi 12T) may have hidden latches under the lid — don't put too much effort into it.
5. Unscrew all the screws on the metal plate (usually 8-12 pieces). Remember the location - the screws can vary in length!
6. Disconnect the battery plume with a shoulder blade. Don't pull the plumes by force, they're fragile and easily torn.

After that, you will have access to the internal components: motherboard, camera, speakers, etc. To replace the battery or screen will require additional actions, which we will discuss below.

Features of dismantling smart watches and fitness bracelets Xiaomi

The Mi Watch and the Mi Band are different from smartphones, and their body is usually glued or snapped, and the internal components are miniature.

• 🕒 Mi Band 7/8: The lid is mounted on the latches, and to remove it, you need to carefully apply a plastic map around the perimeter, and inside you find a battery (soldered to the board) and a vibrating motor.
• ⌚ Mi Watch (series) S1, Lite: back cover glued. Opening will require the thermophene and a mediator. Under the cover, battery and sensors (pulsemeter, SpO₂).
• ⚠️ Xiaomi Smart Band Pro: has a touchscreen soldered with a plume.Shooting requires a soldering iron and microelectronics skills.

The main difficulty is miniature plumes and fragile contacts. For example, in the Mi Band 6, the display plume is glued to the board, and it is easy to tear off when you sloppy movement. If you are disassembling a watch for a replacement battery, note that in most models it is soldered, and you will need a soldering station with a thin sting.

⚠️ Note: Xiaomi smartwatches often use waterproof glue (e.g. Mi Watch) S1). After disassembly, the leakage is broken and the device will lose water protection. If you want water protection, apply a new glue after assembly (for example, apply a new glue, LOCTITE 406).

Disassembly of tablets and routers Xiaomi: key differences

Xiaomi Pad and Mi Router are less common, but sometimes it’s necessary to upgrade memory or clean up dust.

• 📱 Xiaomi Pad 5/6: The back cover is attached to the latches and glue, and underneath it is a battery (4 plume! SSD-The storage device (in some modifications) to replace SSD You'll need to cut off the contacts.
• 📶 Mi Router 4A/AX3000: It's screwed into a screwdriver, and it's a board with a Qualcomm chip inside. IPQ6000 (into AX-The main danger is static electricity, which can damage the chips.

Xiaomi tablets often use double-sided tape to fix the battery. To remove it, pull a special loop (if any) or gently tuck a plastic blade with a hairdryer before heating. In routers, the main problem is fragile antenna connectors. When disassembling, do not pull the antennas, but unscrew them counterclockwise.

Common Mistakes and How to Avoid Them

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

1. Pipe damage. In Redmi Note 11, for example, the fingerprint scanner plume goes over the battery and breaks easily. Solution: before you take off the battery, unplug all the plumes, even if they don't interfere.
2. The screws in Xiaomi often differ in length (e.g., in the POCO X5 there are 3 kinds).Solution: spread them out on a magnetic mat in order of extraction or photograph the location.
3. Plastic overheating. When heated with a hair dryer, the lid can deform (relevant to the Xiaomi 13 Lite with a glossy body). Solution: warm in short intervals (10-15 seconds) and check the lid's malleability.
4. They forget to turn off the battery. If you start to work with the board with the battery connected, you can burn the components. Solution: first of all, disconnect the battery plume.

Another common problem is damage to sealing rubbers in waterproof models (e.g., Xiaomi 13 Pro with IP68 certification). If the gum breaks or shifts, the device loses its protection from moisture. When assembled, check its integrity and correct position.

💡

If you are disassembling a smartphone to replace the battery, check its voltage with a multimeter before installing a new one. It should be within 3.7-4.2V. Batteries with a voltage below 3.5V may not start the device or damage the power controller.

When the Disassembly is Inappropriate: Alternative Solutions

Disassembly of Xiaomi devices is not always justified, and in some cases it is easier and cheaper to contact a service center or consider alternative options:

• 🔋 The battery is bloated, but it's still working: don't try to disassemble it! The risk of fire or damage to the board is too high.
• 💧 Liquid: If your smartphone doesn't turn on after contact with water, don't disassemble it immediately. First, wet the moisture with a napkin, dry it with rice (24 hours) or silica gel.
• 📱 The screen is cracked, but the sensor is working: in Xiaomi models, the display and touchscreen are often glued together.
• 🔌 The charging connector is not working: 80% of the time, the problem is contamination of the contacts. Try brushing them with alcohol and toothpicking before disassembling them.

Also note that some components (such as the cameras in Xiaomi 13 Ultra flagships) are calibrated in the factory, and the photo quality may deteriorate after replacement, and software configuration through service utilities (such as Mi Flash Pro) will be required.

If your device is warranty-worthy, first contact the official Xiaomi service.Disassembly will void the warranty, and repairs in unofficial workshops can cost more than fixing the problem under warranty.
