Disassembly of smart watches Xiaomi Amazfit: instructions for models GTR, GTS, Bip and Neo

The Xiaomi Amazfit smartwatch has become popular thanks to a combination of affordable price, functionality and stylish design. However, even the most reliable equipment sometimes needs to be disassembled - to replace the battery, repair the screen or clean the dust. Unlike classic mechanical watches, smart gadgets require caution: improper disassembly can lead to damage to the plumes, detachment of the display or failure of sensors.

This article will help you disassemble the watch without the risk of failure, even if you have never repaired electronics. We will look at the design features of different lines (Amazfit GTR, GTS, Bip and Neo), list the necessary tools and give step-by-step instructions for typical errors. Importantly, the procedure voids the warranty, so resort to it only as a last resort or if the warranty period has already expired.

Preparation for disassembly: tools and security measures

Before you start, make sure you have everything you need, and if you don't have at least one tool, you can make it harder or damage the body, and here's the minimum set:

• 🔧 Plastic mediators (2-3 pieces) - for careful licking of the lid. Metal blades leave scratches!
• 🔥 Building hair dryer (or powerful household) - to soften glue. Temperatures 60-80°C is enough.
• 🧲 Suction cup (3-5 cm in diameter) - will help to raise the display after heating.
• ⚡ Screwdriver. T4/T5 (depending on the model) - for screws inside the body.
• 🧴 Isopropyl alcohol 90%+ — glue-residue.
• 📦 Container for screws - so as not to lose small details.

Also prepare your workspace: a table with good lighting, an antistatic mat (or at least a regular napkin), a magnifying glass (for small parts) and spare batteries/ plumes if you plan to replace. Don't work on a carpet or couch - static electricity can damage electronic components.

⚠️ Warning: If the watch has been in water or has been hit, disassembly can be dangerous! Condensation inside the case or a damaged battery can cause a short circuit.

Design differences of different models Amazfit

The case of the Xiaomi Amazfit watches differ in the way they are built, so there is no universal instruction. Below are the key features of popular lines:

The GTR and GTS models have a 3M double-sided tape glue on the body, which becomes elastic when heated, but does not lose all of its adhesiveness, which means that once the watch is dismantled, it will have to be glued back together again, so the original adhesive will not recover.

The Bip U/S and Neo have a simpler design: the body consists of two halves, held together by latches or screws, but the Neo has additional mounts hidden under the rubber buttons that are easy to miss.

💡

Before disassembling, take a photo of the watch from all sides, which will help to properly assemble the case back, especially if you are doing repairs for the first time.

How to Disassemble the Amazfit GTR/GTS

These are the most popular models, but also the most difficult to disassemble.

1. Turn off the watch and remove the strap. The GTR 4 has a strap attached to spring pins, and put a thin screwdriver in it.
2. Heat the body with a hair dryer around the perimeter of the display for 2-3 minutes. Keep the hair dryer at a distance of 5-7 cm so as not to overheat the battery.
3. Put the display on a plastic pickup on either side. If it doesn't, heat it up for another 1 minute. Don't use metal!
4. Disconnect the plumes: 🔋 Battery plume (orange connector). 📱 Display plume (black, under metal latch). 🔊 The dynamic plume (if any, the GTR 4).

Twisted the screws.

You can then remove the motherboard and access the battery or other components. Note that the GTS 3 has a display plume glued to the board, so you need to tear it off very carefully, you better stick it with a thin blade.

⚠️ Warning: If the battery is turned off immediately, it is a sign of a short circuit on the board. Immediately turn off the power and check the contacts for moisture or oxidation.

Amazfit Bip U/S Disassembly: A Simple Way to Deal

Bip models are much easier to disassemble because they don't have glue.

1. Remove the strap and find a slot between the body and the back cover (usually near the button).
2. Put a plastic mediator in the groove and gently guide the perimeter, snapping the clamps. The lid will be removed with a characteristic click.
3. Under the lid, you'll see a battery glued to the body. Unplug its plume (white connector).
4. Unscrew the 2 screws (T5) and remove the motherboard.

Replacement process:

1. Disconnect the old battery by disconnecting the plume.
2. Put a plastic shoulder blade on the battery (it is glued to the body).
3. Clean the place of planting with alcohol from glue residues.
4. Stick a new battery, plug in the plume and check charging.

A critical error: Reverse battery (plus to minus) will disable the power controller. The plume usually has a + marking and, if it isn't, check the photo of the original battery.

💡

After replacing the battery, be sure to check the charging clock for 30 minutes. If the case heats up above 40°C, turn off the power immediately and check the contacts.

Common Mistakes and How to Avoid Them

Even experienced craftsmen sometimes make mistakes that lead to breakdowns.

• 🔥 Overheating of the body with a hairdryer. Temperature above 90.°C can melt plastic or damage the battery. Use a thermometer.
• 🛠️ Loss of screws, screws on the Amazfit are small and magnetized, work on non-magnetic surfaces.
• 💧 Isopropyl alcohol dissolves the oleophobic coating of the display. Apply it only to the body.
• ⚡ Forgetting to turn off the plumes before you take off the board, it can tear the contacts off.

Another common problem is damage to the waterproofing gasket, where waterproof models (such as the GTR 4) have rubber bands on the perimeter of the body, and if they are broken or mislaid during assembly, the watch will lose its leakiness.

⚠️ Attention: If the watch doesn't turn on after assembly, but when you connect to charging it vibrates, the problem is the plume of the display. Check if it sits tightly in the connector. Sometimes it helps to lightly press the screen after assembly.

Building a watch: how to avoid mistakes

It's often harder to assemble a watch than to disassemble it.

1. Check all the plumes for contamination, wipe the contacts with alcohol.
2. Twisting the screws cross-cross to avoid skewing the board.
3. Apply the new adhesive to the body before installing the display. Use B-7000 adhesive or 0.2mm thick 3M double-sided tape.
4. Check the buttons before final assembly. In a GTS 3, the button often sticks if the body is clamped too tight.

After assembly:

• 🔋 Charge your watch 100% and check your work time.
• 💦 Check the water protection (if the model supports): dip the watch in water for 10 seconds (without pressing buttons!).
• 📱 Sync with the Zepp app to make sure the sensors are up and running.

If the screen became less sensitive after assembly, you probably pressed the display too hard against the case. Take apart the watch and add a thin pad (like a piece of paper) between the battery and the back cover.
