Disassembly Xiaomi Amazfit Bip: a complete guide with photos and expert advice

The Xiaomi Amazfit Bip fitness bracelet has become a cult gadget thanks to its combination of affordable price, monthly autonomy and wide functionality. However, over time, even such a reliable device can require repairs: a bloated battery, a cracked screen or moisture entering the case force users to look for ways to disassemble the bracelet themselves. In this article, detailed photo instructions, what tools are needed, what underwater stones await beginners and how to avoid typical mistakes.

It's important to understand that the Amazfit Bip is not designed for custom repairs, its body is sealed and its internal components are fragile. 90% of the breakdowns in self-disassembly are due to the use of inappropriate tools or excessive effort when opening the case. If you are not sure about your skills, you should contact the service center. But if you decide to act on your own, follow our recommendations.

Preparation for disassembly: tools and security measures

Before you start, gather all the tools you need, and if you don't have one tool, you can damage the body or the internal components, and here's the minimum set.

• 🔧 Plastic mediators (2-3) for the accurate fitting of the case. Metal screwdrivers or knives are not to be used!
• 🔥 Dryer or thermo-air station - for softening the glue (temperature 60-80)°C).
• 🧲 Magnetic screwdriver (cross, size PH00) - for unscrewing screws.
• 📦 A screw container to keep the small parts from being lost (there are only 4 in the Amazfit Bip, but they are tiny).
• 🧴 Isopropyl alcohol (90%+) — Cleaning contacts and removing glue residues.
• 🩹 Gloves and safety glasses – The bracelet battery may be swollen and the glass sharp.

Also prepare the workplace: a table with good lighting, an antistatic mat (if any) and a magnifying glass - some Amazfit Bip parts are smaller than a rice grain.Do not work on a carpet or sofa: static electricity can damage the board, and a lost screw will be hard to find.

⚠️ Warning: If the bracelet has been exposed to water, be sure to dry it in rice or silica gel for at least 48 hours before disassembling.

The step-by-step disassembly of the Xiaomi Amazfit Bip

The process begins with the back cover being separated from the main body, and this is the most critical stage, where 80 percent of the newcomers make mistakes.

1. Heat the body. Turn the dryer on to the minimum power and evenly warm the back cover of the bracelet for 2-3 minutes, holding the hair dryer at a distance of 5-7 cm The goal is to soften the glue, but not melt the plastic. The temperature of the body should be warm, but not hot.
2. Push the mediator. Put the plastic mediator in the gap between the body and the back cover (better start with the area next to the button). Carefully drive the mediator around the perimeter, gradually increasing the gap. Do not force - if the cover does not respond, warm up for another 1 minute.
3. Remove the lid. When the mediator passes around the perimeter, the lid should separate. If it's stuck in some places, don't pull it, warm up the problem areas again.

When you remove the lid, you'll see the battery glued to the board. Don't pull it, you'll first have to disconnect the display plume and the battery connector. Use tweezers or a plastic shovel to gently lift the black battery connector (it's next to the button).

Now you can unscrew the 4 screws (they're hidden under the stickers -- remove them carefully with tweezers) and remove the board. Be careful: there are sensors on the back of the board that are easily damaged.

Typical Problems and How to Avoid Them

Even with a careful disassembly, you can encounter surprises, and here are the most common problems and ways to solve them:

Pay special attention to the leakage after assembly. If you have replaced the battery or display, be sure to apply a thin layer of silicone sealant around the perimeter of the lid before installing it. This will protect the bracelet from moisture. To check the leakage after assembly, place the bracelet in a plastic bag with silica gel for 12 hours — if there is no condensation inside, everything is fine.

⚠️ Warning: If you notice that the Amazfit Bip battery has swelled to the point where it has deformed the body, don't try to puncture or heat it. Lithium polymer batteries can ignite if damaged, in which case the only safe option is to replace the battery at the service center.

💡

Before assembly, take a picture of all the plumes and screws on the board, which will help avoid errors in reverse assembly, especially if the process takes several days.

Battery replacement: the choice of parts and nuances of installation

The average life of an Amazfit Bip battery is 2-3 years, and then the capacity drops by 30-50%, and the bracelet requires charging every 2-3 days, and replacing the battery is the most common reason for disassembly.

• 🔋 The original battery is labeled BL-37B and has a capacity of 190 mAh. Counterfeiting often has a smaller capacity (150-170 mAh) and fails faster.
• 🛒 Where to buy: checked stores - AliExpress (sellers with a rating of 98%+), Banggood or specialized service centers. The price of the original battery is 500-800 rubles.
• ⚡ No soldering required -- the battery plugs in through the connector, but the contacts need to be cleaned with alcohol before installation.
• 📏 Matters thickness: A bloated battery can be 0.5-1 mm thicker than the original battery. If the new battery doesn't fit in the groove, don't press, look for a thinner one.

Replacement process:

1. Disconnect the old battery by smacking it with a plastic spatula. If it's glued, use isopropyl alcohol to dissolve the glue.
2. Clean the contacts on the board and the new battery with a cotton swab dipped in alcohol.
3. Install a new battery, making sure it's firmly in the groove. The connector should snap with a slight click.
4. Before assembly, check the voltage with a multimeter (should be 3.7-3.8V).

After you change the battery, the bracelet may not turn on immediately, which is normal. Connect it to charging for 10-15 minutes, then try to turn on the button. If the charging indicator is not on, check the density of the battery connector.

Replacement of the display: when it is necessary and how to choose the screen

The Amazfit Bip display is one of the most vulnerable places, and it can crack from impact, lose sensitivity due to moisture, or simply fail over time (vertical stripes appear, flickering), and it's harder to replace the battery, but it's also possible to do it at home.

Signs that the display needs to be changed:

• 💥 Visible cracks or chips on glass.
• 📉 Dead zones that do not respond to touch.
• 🌈 Permanent artifacts (colored stripes, flickering).
• 🔳 Complete absence of image when backlighting is running (lights white).

When choosing a new display, pay attention to:

• 🆔 Model: The original display is labeled TFT 1.28" 176×176. Counterfeiting may have a different resolution or color reproduction.
• 🔧 Compact: The kit must have a plume and sealing gum, and without it, the tightness will be impaired.
• 💰 Price: the original display costs 1200-1500 rubles. Cheap options (up to 800 rubles) are often defective.

Replacement process:

1. Disconnect the plume of the old display from the board (it is fixed by a latch - carefully lift it with tweezers).
2. Take the display off with a plastic blade around the perimeter, and be careful, the glass is fragile.
3. Install a new display, make sure the plume is not twisted. Lock the latch.
4. Check the screen before full assembly: connect the bracelet to charging and make sure the image is clear and the sensor responds to touch.

⚠️ Warning: If the bracelet overheats or discharges quickly after the display is replaced, the new screen is likely to be unoriginal and power-efficient, in which case it is better to return the old display (if it worked at all) or order the original part.

💡

When replacing the display, never use metal tools to smack the glass – even the slightest scratch on the plume can lead to a loss of screen sensitivity.

Bracelet assembly and performance check

Assembling the Amazfit Bip after repair requires no less care than disassembling.

1. Contact check. Make sure all plumes (display, buttons, vibratory motor) are tightly fixed. Connectors should snap with a click.
2. Battery stacking. Battery should be flat, smooth, and if it's a little thicker than the original, you can gently press it down with a plastic spatula, but don't overdo it.
3. Pressurization. Apply a thin layer of silicone sealant (such as Dow Corning 7091) around the perimeter of the back cover. Avoid getting the sealant on the charging contacts!
4. Closing the case. Start with the area next to the button, then gradually press the lid around the perimeter. Use clamps or screeds to ensure a uniform pressure for 10-15 minutes.

After assembly, perform the test:

1. Connect the bracelet to charge. The indicator (red or green) should light up.
2. Press the button – the bracelet should vibrate and turn on.
3. Check the sensor: swipe across the screen, make sure the swipes are working.
4. Synchronize the bracelet with the Mi Fit application and check all the functions: pedometer, pulsemeter, notifications.

If something doesn't work, don't panic. Take the bracelet apart and check:

• 🔌 The density of all plumes.
• 🔋 The polarity of battery connection (plus and minus should not be confused).
• 📶 Bluetooth antenna integrity (thin wiring next to battery)

Frequent Beginner Mistakes and How to Avoid Them

Even with the instructions, many people make the same mistakes. Here are the top -5 of misses and how to prevent them:

1. Using metal tools: Knives, screwdrivers or scissors scratch the body and can close contacts on the board. Solution: buy a set of plastic mediators (cost 100-200 rubles).
2. Overheating the body with a hair dryer. Temperatures above 80°C deform plastic and can melt the glue, which then hardens with lumps. Solution: use a temperature-adjusted thermo-air station or keep the hair dryer at 10 cm.
3. The screws in the Amazfit Bip are tiny (2-3 mm long) and easily lost. Solution: use a magnetic mat or a container with a lid.
4. The sealant gets on the contacts. Silicone or glue on the charging contacts disrupts conductivity. Solution: apply the sealant with a thin brush or toothpick.
5. Ignoring static electricity. Discharges can damage the board even if you don't feel the impact, solution: work in an antistatic bracelet or periodically touch an earthed object (such as a heating battery).

If you’ve never done electronics before, practice on an unnecessary gadget (such as an old charger or broken headphones) to help you feel the effort required to tweak the cases and avoid errors when working with the Amazfit Bip.

💡

If the bracelet is working after assembly but discharges quickly, check if there are any small metal particles (such as screw fragments) left inside the case, which can close contacts and increase energy consumption.
