How to get the Xiaomi Mi Band 4 watch from charging: 5 proven ways

The Xiaomi Mi Band 4 is one of the most popular fitness trackers, but even such a reliable device has a weak point: a charger. Many users face the problem when the watch capsule “fits” to the contacts of the dock and does not want to be removed in the usual way, and the longer the bracelet is on charge, the higher the risk that plastic latches will deform or break if improperly removed.

In this article, we will explore all the possible reasons why the Mi Band 4 can get stuck in charging, from overheating to factory contact defects, how to remove a watch without damage even in the most advanced case, which tools to use and which methods to abandon, and we will give recommendations for prevention so that the problem does not recur in the future.

Importantly, if you've tried to pull out your watch by force and you hear a characteristic crunch, don't panic. In 80 percent of cases, the capsule can be saved, but you need to act carefully and according to instructions.

Why is Xiaomi Mi Band 4 Watch Stuck in Charging?

The problem of sticking the capsule to the dock is typical of the Mi Band 4 and is associated with several factors.

• 🔥 Overheating of contacts - with prolonged charging (more than 2 hours), the plastic softens and deforms, and the metal "tickles" of the charger literally grow into the case of the watch.
• 💧 Oxidation or pollution – sweat, dust and moisture over time form a sticky coating on the contacts that acts as glue.
• 🏭 Factory marriage – in the early Mi Band 4 (2019 release) latches of the docking station were too tight, which led to a spell.
• ⚡ Unoriginal charger – cheap analogues often have inaccurate groove geometry, causing the capsule to get stuck.

According to service centers, 60 percent of the time, the problem is caused by a combination of overheating and pollution, such as when you charge your bracelet after a workout, when you have salty sweat on your contacts, and then leave it on charge all night.

Preparation for extraction: what to do before Attempts

Before you try to pull out the watch, assess the situation:

1. See if the metal contacts in the dock are bent, and if they're deformed, don't pull the capsule by force, it can damage the connector inside the watch.
2. Check if the charger is on. If the Mi Band 4 is still powered, disconnect the charger from the mains.
3. Examine the capsule body for cracks, and if the plastic has already burst, further manipulations may exacerbate the problem.

If the watch is not completely stuck (protrudes at least 1-2 mm), try to gently sway the capsule left-right, without exerting effort.

Cool the docking station (if it is warm)

Disconnect the charger from the socket

Prepare a flat screwdriver or mediator

Examine contacts for oxidation

Take a picture of the clock (for the service center)

Do not use sharp objects (knives, needles, scissors) to extract the internal components of the Mi Band 4, and the risk of damage is greater than 90%.

Method 1: Extracting with a thread (for mild cases)

This method works if the watch is stuck due to minor contamination of the contacts or mild deformation of the plastic.

• 🧵 Strong thread (for example, a fishing line with a thickness of 0.2-0.3 mm)
• 🔍 Lupe or flashlight (for accuracy)
• 🧴 Alcohol wipes (for cleaning contacts)

Algorithm of action:

1. Wipe the docking station and the visible part of the capsule with an alcohol napkin to remove fat and sweat.
2. Strip the thread between the watch case and the charger. If there is no gap, gently tuck the capsule on the side with a plastic card (not metal!).
3. Move the thread in sawing movements left-right, gradually deepening, the main thing is not to pull up, namely, to "cut" the connection.
4. Once the thread is 2-3 mm deep, pull it perpendicular to the dock body. The capsule should come out with a characteristic click.

If the thread breaks or slides, try moistening it with a drop of silicone lubricant (e.g. WD-40).Do not use oil or water-based liquids - they can damage the electronics.

💡

After removal, wipe the contacts of the clock and the docking station with a cotton swab dipped in isopropyl alcohol (concentration 90% or higher), which will remove the residue of oxides and prevent re-filling.

Method 2: Disassembly of the docking station (for medium cases)

If the thread doesn't work, you'll have to partially disassemble the charger, which is a technique that requires precision, but allows you to retrieve the watch even when the plastic is severely deformed.

You'll need:

• 🔧 Tiny cross screwdriver (for example, for glasses)
• 📱 Plastic mediator or guitar record
• 🔥 Fen (optional, but will help with "staying»)

Step-by-step:

1. Turn over the dock and find two small screws (usually hidden under the sticker) carefully remove the sticker by heating it with a hair dryer at minimum power.
2. Unscrew the screws and unplug the charger, and inside you'll see a board with contacts and a plastic tongue that holds the capsule.
3. If the plastic is deformed, bend it carefully with a mediator. Don't make any effort on the capsule itself!
4. If the contacts are oxidized, clean them with a blower or alcohol. Then collect the dock back and try to remove the watch with a thread (mode 1).

⚠️ If you see that the dock board has blackened or the capacitors have ballooned, stop the manipulation immediately).

Method 3: Thermal method (for "steeped" clocks)

If the Mi Band 4 capsule is literally welded to the contacts, controlled heating will help, a technique based on the physical property of plastic: when it is heated, it expands, and when it is cooled, it shrinks.

Important: Do not use open fires (lighters, matches) – this melts plastic and can damage the watch battery.

Instructions:

1. Place a dock with a stuck clock in the freezer for 15 to 20 minutes. The cold will make the plastic more fragile.
2. Take out the device and immediately direct hot air from the hair dryer to the joint (hot, but not maximum!) Keep the hair dryer at a distance of 10-15 cm so as not to overheat the battery.
3. After 30 to 40 seconds, try to gently sway the capsule, and if it doesn't work, repeat the cooling/heating cycle.
4. Once the clock is moved, remove it with a thread (mode 1).

This method works in 90% of the cases of "fixing", but it requires patience. Do not try to speed up the process by increasing the temperature - this can deform the capsule body.

Method 4: Mechanical impact (extreme case)

If all the previous methods have failed, then mechanical extraction is left, which is risky, but sometimes the only way.

You'll need:

• 🔪 The Dumb Side of a Knife or Plastic Spattle
• 🧲 Small Neodymium Magnet (optional)
• 📸 Macrophoto lens for monitoring

Algorithm:

1. Secure the docking station in the vise or between two books so that it does not move.
2. Insert a plastic spatula into the gap between the watch body and the docking station, move from edge to center, as if rocking the capsule.
3. If the clock has moved but it doesn't go out, use a magnet. Hold it to the end of the capsule (where the speaker is) and pull it upwards. The magnetic field will help you overcome the last resistance.
4. After extraction, inspect the watch case for cracks. If you have any, fill them in. UV-glue and dry under an ultraviolet lamp.

⚠️ Attention, if you hear a crunch inside the capsule when you're mechanically extracting it, it could have burst the battery or gone off the display plume:

1. Put the clock aside immediately (do not turn it on!).
2. Place them in a sealed silica gel bag for 24 hours.
3. Contact the Xiaomi service center - self-repair can be dangerous (the risk of fire of a lithium polymer battery).

What to do after extraction: preventing re-entry

To avoid recurring problems, follow these rules:

• ⏱️ Do not leave your watch on charge longer than 2 hours – after full charge (100%) disconnect the docking station from the network.
• 🚿 Wash your contacts after exercise or shower. Use lilaless wipes and alcohol.
• 🔌 Use only the original docking station. Cheap analogues often have inaccurate groove geometry.
• 🌡️ Avoid overheating – do not charge your watch in direct sunlight or near heat sources.
• 🔄 Once a month, clean the capsule connector with a toothpick wrapped in microfiber.

If you notice that the watch is beginning to "tight" into the docking station, that's the first sign of a future stuckness.

1. Check the contacts for deformation.
2. Try charging the watch in the inverted position (capsule down).
3. If the problem persists, replace the docking station.

💡

The original docking station for Mi Band 4 costs about 500-700 rubles, but its replacement is cheaper than repairing the watch after unsuccessful extraction (the repair price is from 1500 rubles).
