How to disassemble Xiaomi wristwatch without damage: the full guide 2026

Disassembling Xiaomi smartwatches is a challenge that owners face when replacing the battery, repairing the screen or cleaning from dust. Despite the compactness of the devices, the process requires accuracy and knowledge of the nuances from choosing a screwdriver to properly removing adhesive joints. In this article, you will find step-by-step instructions for popular models (Mi Band 6/7, Xiaomi Watch S1/S2, Amazfit GTR/GTS), a list of necessary tools, as well as warnings about typical errors that lead to breakage.

Many users are afraid to damage the device, and for good reason: improper exposure to plumes or connectors can make the watch inoperable. We will tell you how to minimize risks, what alternative methods of disassembly exist (for example, without special equipment), and what to do if something goes wrong — FAQ Answering frequent questions and advice on choosing spare parts.

If you've never been electronics expert, start by looking at video instructions for your model to help you visually assess complexity, and remember, Xiaomi's warranty doesn't apply to devices with autopsy marks.

What Xiaomi models can be disassembled independently?

Not all Xiaomi smartwatches are equally repairable, for example, the Mi Band 3-7 has a modular design with latches, while the Xiaomi Watch S1 Pro is sealed and requires professional equipment. Below is a comparison table of the complexity of disassembly for popular models.

Pro models (like the Watch S1 Pro) typically have enhanced moisture protection (5 ATM), making it harder to disassemble. If your goal is to replace your battery, look at the Mi Band: their batteries are mounted on connectors rather than soldered, making it easier to do so.

⚠️ Warning: Sapphire glass watches (such as the Amazfit T-Rex Ultra) require the use of plastic shoulder blades – metal tools leave scratches.

Tools you need: what to buy and where to save

Xiaomi will need a minimal set of tools to disassemble the watch, but some of them are better not to replace with improvised means. For example, plastic mediators (for disengaging the case) can be found in the remakes for smartphones, but special screwdrivers (T3, T5) you will have to buy separately – they are thinner than standard ones.

• 🔧 A set of screwdrivers with bats T3, T5, PH00 (hull-rotor).
• 📱 Plastic mediators or shoulder blades (thickness 0.1–0.2 mm).
• 🔥 Hair dryer or thermo-air station (for softening glue).
• 🧲 Magnetic mat (so as not to lose the screws).
• 🔋 Multimeter (to check the battery after replacement).

Where to save money:

• 💡 Instead of a hair dryer, you can use hot water (immerse the watch in water at a temperature of 60-70).°C for 1-2 minutes - the glue will soften).
• 💡 Plastic mediators will replace guitar mediators or credit cards (but they are less flexible).
• 💡 For the storage of screws suitable tray for ice with a magnet at the bottom.

⚠️ Warning: Do not use superglue to reverse assemble! Only double-sided tape will do for sealing. 3M or special glue LOCTITE 401.

Step-by-step: disassembly Xiaomi Mi Band 6/7

The Mi Band 6/7 models are similarly designed, so the instructions are suitable for both, and the main difficulty is to disconnect the screen from the body, which is held on the glue and latches.

1. Take the strap off. Press the button on the back of the module and pull the strap up. In some models, the strap is attached to the clamps, which you need to gently tuck your nail.
2. Heat the case. Use a dryer at minimum power (or immerse the watch in warm water for 1 minute) The goal is to soften the adhesive around the perimeter of the screen.
3. Put the screen in the gap between the screen and the body on the side (where there is no button), carefully guide the mediator around the perimeter until the screen disconnects.
4. Turn off the plume. Under the screen, you'll see a flexible plume attached to the motherboard, and gently lift it by the black latch (don't pull the plume!).

Now you'll have a motherboard with a battery in your hands to replace the battery.

1. Unplug the battery (it is glued to bilateral scotch).
2. Disconnect the battery connector from the board.
3. Install a new battery (note the polarity!).

The critical point is that the screen plume in the Mi Band 7 is thinner than in the 6th model, and if you accidentally rip it, you'll have to change the entire screen — no tails are sold separately.

Disassembly Xiaomi Watch S1/S2: difficulties and solutions

Watch Xiaomi Watch S1/S2 have a metal case and sapphire glass, which complicates disassembly.The main problem is sealed glue around the perimeter, which requires heating to 90-100 ° C. Without a thermo-air station, the risk of damaging the screen increases by 3 times.

Step-by-step process:

1. Remove the back cover. It's mounted on 4 screws (T5). After unscrewing, apply the lid with a plastic blade, which sits on a sealant.
2. Disconnect the battery. It's glued to the body. Use the mediator to gently separate it (don't pierce!).
3. Take the motherboard off. It's mounted on 2-3 screws. Be careful with the antenna module (thin wire near the charging socket).
4. Separate the screen. Heat the body with a hair dryer (100°C) and gently tuck the screen with a suction cup (as for smartphones).

Features of the Watch S2 model:

• 🔋 The battery is soldered to the board (unlike the S1, It's on the plug. You need a soldering iron to replace it.
• 📡 Antenna module is fragile – if damaged, the watch will lose contact with the phone.
• 💧 After assembly, be sure to check the tightness (immerse the watch in water without a strap for 10 minutes).

💡

If you’re disassembling the Watch S1 Pro, pay attention to the extra screw under the button – it’s easy to skip and then the case won’t open.

Common Mistakes and How to Avoid Them

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

1. Screen plume damage, cause: too much pressure from the mediator or wrong angle of tacking, Solution: Use two shoulder blades simultaneously from opposite sides to evenly distribute the load.
2. Antenna wiring break. It's relevant for the Watch S1/S2. It's because of the sloppy motherboard extraction. Solution: Set the board with tweezers over the edges, don't pull the wires.
3. Overheating of the body. If you use a hair dryer at maximum power, the plastic parts will deform. Solution: Keep the hair dryer 10 cm away and heat it for no longer than 30 seconds in one approach.
4. Loss of screws.The screws in Xiaomi watches are tiny and easily lost.Solution: Use a magnetic mat or a tray with splits.

Another common problem is that the touchscreen is broken after assembly, and this happens when the screen plume is not fully inserted into the connector, and make sure that the latch on the connector is closed before the click.

⚠️ Warning: If the watch doesn't turn on after assembly, check the battery polarity. In Mi Band models, plus and minus are often marked in fine print on the board - use a magnifying glass.

💡

90% of Xiaomi watch breakdowns are due to careless handling of plumes and antenna wires. Always check connections before final assembly!

What if the clock doesn’t work after the breakup?

If the device fails to turn on or malfunctions after assembly, don't panic. In most cases, the problem can be fixed without professional help.

• 🔋 Check the battery: Connect the watch to charge for 30 minutes - maybe the battery is dead. Use the multimeter to check the voltage (normal: 3.7–4.2V).
• 🔌 Check the connections: Take the watch apart again and make sure all the plumes and connectors are tightly connected.
• 📱 Check the software: Connect the watch to the Mi app Fitness/Zepp Reset the settings to factory settings (Settings) → About the device → Reset).

If the clock is on but does not respond to touch, the problem may be:

• The wrong screen plume.
• Damaged glass (cracks can block the sensor)
• Firmware failure (try to reflash through Mi Fit Tool).

In extreme cases, if self-repair does not help, contact the service center. indicate that you have already tried to disassemble the watch - this will save time for the master.

Where to buy spare parts for Xiaomi watches?

When replacing parts, it is important to buy original or certified parts. Poor-quality counterparts (such as batteries without protection) can disable the motherboard.

Buying tips:

• 🛒 On AliExpress, look for sellers with a rating above 98% and reviews with photos.
• 🛒 Before buying a battery, check its capacity (for example, for Mi Band 7 the norm is 125 mAh).
• 🛒 If you buy a screen, check whether the set is glue for installation.

⚠️ Note: Avoid tagged parts "OEM" Without a certificate, it could be a fake. Original parts usually have a hologram or a serial number.
