How to properly disassemble a Xiaomi device: from a smartphone to a router

Disassembling Xiaomi equipment is a task that every owner sooner or later faces. Whether you want to replace the battery in the Redmi Note 12, clean the cooling system in the Mi TV Q2 or update the antennas in the Xiaomi Router AX6000, you can not do without knowing the design features. Unlike Apple or Samsung, Xiaomi devices often have unique mounts, hidden latches and non-standard connectors, which makes the process of disassembling both simple (driven by the modular architecture) and dangerous (dribly plumes).

This article doesn’t just list the steps, it explains why you should do it this way, not the other way. We’ll take a look at the tools (and why a cheap plastic mediator can cost you a display), look at the hidden traps in the design of different series (POCO, Mi, Redmi), and show how to avoid mistakes that make the device “brick.” For clarity, we’ll give mounting schemes, comparative tables of complexity of disassembly, and even unique data on the percentage of failures in self-repair (a 2023 study from iFit for Xiaomi).

We warn you right away that if your device is warranty, the disassembly will invalidate it, but if you're willing to take a risk, go ahead!

1.Preparation: tools and safety

The first rule of Xiaomi disassembly is no improvisation: a plastic card instead of a mediator, a knife instead of a screwdriver or tweezers instead of a screen sucker is a surefire way to get a chipped case or a torn plume. Here is the minimum set that any brand device will need:

• 🔧 A set of screwdrivers with bats PH00, T3, T5 (for smartphones and H1.5 (Xiaomi bits are often of unusual depth, so cheap sets may not be suitable.
• 🧲 Magnetic mat or tray for screws – in Xiaomi devices, they can be up to 20 pieces of different lengths (for example, in the Mi 11 Ultra).
• 📱 Plastic mediators 0.1–0.2 mm thick (metallic scratches the body). POCO F5 You will need a mediator with a rounded end.
• 🔥 Hair dryer or thermoplatform (for devices with adhesive screen mounting, for example, Redmi Note 10 Pro).°C.
• 🧴 Isopropyl alcohol (90%+) — to clean the contacts and remove glue residues, acetone or solvent cannot be used!

Pay special attention to the antistatic bracelet. The chips in Xiaomi devices (especially the motherboards of Snapdragon 8 Gen smartphones) are sensitive to static electricity. If the bracelet is not, regularly touch the grounded metal object.

⚠️ Note: Xiaomi Mix series smartphones (such as the Mix 4) have a graphite gasket for heat sink under the battery, which can easily be broken if the battery is not properly removed, causing the processor to overheat.

2.Stealthphone Disassembly: From Redmi to Mi

Xiaomi’s smartphone design depends on the series and year of release, for example, Redmi’s 2020 (Redmi Note 8 Pro) models were relatively easy to understand — the back cover was mounted on latches and the battery was kept on Velcro. But since the Redmi Note 10, the company has moved to adhesive screen mounting and more sophisticated battery locking mechanisms.

The general disassembly algorithm for most smartphones:

1. Turn off the device and remove it. SIM-map.
2. Heat the edges of the screen with a hairdryer (for models with adhesive attachment).
3. Carefully tuck the display with a plastic mediator, starting at the bottom edge (there is usually an antenna that is easily damaged).
4. Disconnect the display and battery plumes (in the POCO X3 Pro, the battery plume is hidden under the metal plate!).
5. Unscrew the motherboard screws (in Mi 11 there are 12 pieces of different lengths - remember the location!).

Features by model:

⚠️ Note: In smartphones Xiaomi with AMOLED-screens (e.g., Mi) 10T Pro) the display is glued to the touch layer, and if you separate the layers without any special equipment, the screen will fail.

Disassembly of Mi TVs: what is hidden behind the screen

Xiaomi TVs (Mi TV series A, Q, P) have a modular design, but their disassembly requires caution due to high-voltage components. Even after disconnection from the network, capacitors can retain charge up to a few minutes!

Main stages:

1. Remove the TV from the mount and place the screen down on a soft surface.
2. Unscrew the rear cover screws (there are 16 pieces in the Mi TV Q2 75, including those hidden under the stickers).
3. Disconnect the matrix plumes (they are fixed with latches that are easy to break!).
4. Remove the motherboard – in models with Full Array Local Dimming, it is attached to the radiator.

Features:

• 🔌 In Xiaomi TVs with Android TV (Like Mi. TV P1) The motherboard is often combined with a power supply, and if you change the board, you'll need to reconfigure it. EDID.
• 🔊 Dynamics in models QLED They are attached to magnets – they are easy to lose when turning the body over.
• 💡 Lighting in Mi TV The A Pro consists of 96 LEDs arranged in 12 zones. LED I'll have to cut the whole tape.

If the purpose of disassembly is to replace the matrix, note: Xiaomi TVs use a proprietary eDP connector, and non-original panels may not support HDR10+.

4. Disassembly of routers: Xiaomi Router AX6000 and other models

Xiaomi routers (such as the Router 4A Gigabit or AX3600) are simpler than smartphones, but have their own nuances. The main difficulty is the compact layout: antennas, radiators and ports are very dense.

Step-by-step:

1. Turn off the power and remove all cables.
2. Put the plastic plugs on the bottom cover (the AX6000 has 4 of them, and they break easily).
3. Unscrew the screws (in Router 4C they are hidden under rubber legs).
4. Carefully raise the fee – in models with Wi-Fi 6 antenna soldered directly to the board and can come off.

Typical problems in disassembly:

• 📡 Damage. U.FL-antenna connectors (in AX1800 4 of them, and each one is worth it. ~500 rubles).
• 🔥 Qualcomm chip overheating IPQ6000 incorrect assembly (new thermal paste required).
• 🔌 Oxidation of port contacts RJ-45 (Clean only with alcohol, without abrasives!).

⚠️ Note: In Xiaomi routers with support for Mesh networks (for example, Router) AX9000) When disassembling, you reset your sync settings. After assembly, you will need to reconfigure the network through the Mi Home app.

💡

Before disassembling the router, take a picture of the location of the antennas and cables. In models with MU-MIMO (for example, AX6000), improper connection of antennas reduces the speed by 40%.

5. Disassembly of smart watches and bracelets: Mi Band and Watch

Xiaomi’s smartwatches and fitness bracelets (Mi Band 7, Watch S3) are rarely understood — they’re usually easier to replace.

Design features:

• 🔋 In the Mi Band, the battery is soldered to the board, and to replace you will need a soldering station with a temperature not higher than 300°C.
• 🛠️ The Xiaomi Watch case S2 glued with ultrasonic welding - it is almost impossible to disassemble it without damage.
• 💧 Waterproof (5) ATM) It is provided with a rubber seal, which will have to be replaced when disassembled.

If you're still going to get a break-up:

1. Heat the body with a hair dryer (60°C is enough for Mi Band).
2. Use a metal mediator (in this case it is acceptable, since the case is plastic).
3. Disconnect the vibration motor - it is attached to the glue and easily comes off with the board.

The cost of repairs often exceeds the price of a new device, such as replacing the screen of the Xiaomi Watch S1 costs 70% of the cost of the watch.

💡

Disassembling Xiaomi smartwatches is not economically feasible 80% of the time, except for replacing the battery in the Mi Band 6 if you are confident in your soldering skills.

6. Common mistakes and how to avoid them

Even experienced craftsmen make mistakes when disassembling Xiaomi.

Another problem is the loss of propellers. The Xiaomi Mi 11 Lite has 14 of them, all of them of different lengths. If you mix them up, the body doesn't sit tight, and eventually you'll have a backlash.

7 When Disassembly Is Not Needed: Alternative Solutions

Before you take up the screwdriver, check whether it is possible to solve the problem without disassembling:

• 🔄 Software glitches: 60% of Xiaomi smartphone problems are solved by resetting via Fastboot (fastboot erase userdata).
• 🔋 Fast discharge: 40% of the time, it's not the gridded iron that's to blame, but the background processes. Check battery consumption in Settings → Battery.
• 📶 Bad Wi-Fi signal: In routers, Xiaomi helps to change the channel in manual mode (in Mi Wi-Fi, open 192.168.31.1) → Settings → Wireless mode).
• 🔊 No TV sound: 70% of cases are to blame for settings HDMI-CEC (Turn off the option in Settings → System system → Device management).

If the problem is physical damage (for example, a cracked screen or a broken camera), estimate the cost of repair. Replacing the display in the Xiaomi 13 Pro costs 15-20 thousand rubles - sometimes it is cheaper to sell the device for spare parts and buy a new one.
