Owners of popular fitness trackers often face the need to replace the silicone strap with a more stylish one or simply clean it after an intense workout. However, the Xiaomi Mi Band 4 is designed so that the tracker itself, or capsule, sits in it extremely tightly, causing difficulties for inexperienced users. Many are afraid of damaging the fragile body or tearing the silicone while trying to extract the device by force.
There are several proven ways to safely disconnect the module from the mount. In this article, we will look at the official recommendations of the manufacturer, as well as folk life hacks that greatly simplify the process of replacing accessories.
Before starting the procedure, it is important to understand the design of the device. The tracker has no buttons or latches on the body itself, so all actions are performed by physically acting on the elastic material of the strap. Silicone is a durable material, but requires a certain skill when manipulating.
Design features of the Mi Band 4 fastening
The base of the fitness bracelet is an oval capsule that is inserted into a special recess of the strap at the bottom, which is fixed by the tight fit of the walls and a small sideboard that prevents the device from spontaneously falling out when running or swimming, and this side is the one that creates the main resistance during dismantling.
The strap material is made of hypoallergenic silicone, which can become slightly deformed or stiffer over time, and this affects the effort you need to pull the module out, and understanding how the capsule is held helps you choose the right strategy and avoid making mistakes.
It's worth noting that it's often packed with a plug or an extra insert, but the extraction process itself requires care. The fastening is designed to withstand high loads, so the tracker doesn't just fall out.
⚠️ Warning: Do not try to poke the capsule with sharp objects (knife, needle, screwdriver) from the screen or sensors. This is guaranteed to lead to scratches, chips or impaired sealing of the body.
Classic method of extraction without tools
The most common way to remove the Xiaomi Mi Band 4 from the strap is to use your thumbs. You need to take the bracelet in both hands so that your thumbs are under the capsule, on the inside of the strap. The rest of the fingers must be around the device on top for fixation.
The idea is to push your thumbs up at the same time, pushing the tracker out of the nest, and the movement must be confident and sharp, but controlled, and it often requires a lot of effort, especially if the strap is new or strongly clamped.
- 👍 Place your thumbs strictly under the center of the capsule for even pressure distribution.
- 👍 Use the surface of the table or a solid support to lean on your fingers if your strength is not enough.
- 👍 Move the capsule from side to side, shaking it before pulling on yourself.
- 👍 Make sure your hands are dry to avoid slipping during the jerk.
If you don't get it the first time, don't despair. Changing the angle of your fingers or the position of your hands often helps you find the point of least resistance, and the key is not to squeeze the screen itself so as not to damage the matrix.

Use of supporting tools
When the classic method doesn't work because of a tight fit or weak fingers, simple household tools come to the rescue. One of the most effective is using a flat screwdriver with a wide sting or a special plastic tool to open the cases. Many users also successfully use coins or even a toothbrush.
The technique is to gently stick the edge of the tool between the capsule and the strap on the bottom side, so you don't have to pick the tracker itself, you just have to bend the silicone a little bit to release the locking side, and then the capsule is easily removed by hand.
| Tool. | Efficiency | Risk of damage | Recommendation |
|---|---|---|---|
| Big fingers. | Medium | Low. | Basic method |
| Flat screwdriver. | Tall. | Medium. | Only for the experienced. |
| Coin (rib) | Medium | Low. | A safe alternative |
| Toothbrush | Tall. | Low. | Perfect for silicone. |
The great life hack is using an old toothbrush, and the stiff bristles make it easy to get under the edge of the capsule without scratching metal and glass, and just brushing it a few times along the joint, and the tracker will start to come out of the socket.

Folk methods and life hacks of users
Over the years, the Xiaomi Mi Band 4 has been used by the community of users to amass many original ways to solve the tight strap problem. One of the most popular methods is to use a doorknob or the edge of a table, where you place the strap in a gap between the capsule and a hard angle, and then you pull the bracelet down sharply.
Another interesting way involves using tape, where you stick a strip of strong tape to the back of the capsule, and then you pull it abruptly, but it requires caution to avoid leaving any traces of glue on the pulse sensors.
- 🚀 The method of "Door handle": hook the strap by the door handle and sharply pull the bracelet down.
- 🚀 Two Straps Method: Insert the second strap under the capsule and use it as a push lever.
- 🚀 The method of "heating": short-term exposure to warm air (dryer) makes silicone softer.
Some users recommend that you pre-bend the strap backwards from the bend of the capsule, which creates stress in the material and opens the gap through which it is easier to tamper with the tracker. Experiment with different angles of application of force.
💡
Use a screen protector before you change the strap, and if the tool slips, it will hit the film, not the glass of the display, which will preserve the product appearance of the device.
Common mistakes when replacing a belt
Many beginners make mistakes that can cause the device to break, the most common being trying to squeeze the capsule with their nails from the side of the screen, which is not only inefficient, but also dangerous, because the nail can slip and scratch the glass or leave a dent in the frame.
Another mistake is to use excessive force without fixing the bracelet itself, which can result in the tracker flying out at high speed and hitting the floor or wall, always performing the procedure over a soft surface, such as a sofa or bed.
⚠️ Warning: Never use boiling water to soften the strap.High temperature can damage the adhesives inside the capsule or deform the silicone itself permanently.
Also avoid using solvents or oils to lubricate the strap, chemicals can react with silicone, making it sticky or brittle, and damage the coating of the tracker body.
Strap care and pollution prevention
Regularly replacing and cleaning the strap is not only a matter of aesthetics, but also of hygiene. The gaps between the capsule and the silicone often accumulate sweat, dust and skin particles that can cause irritation. Timely removal of the tracker allows you to wash out hard-to-reach places.
Use warm water with mild soap to clean the bag, and after washing, be sure to dry both the strap and the capsule, especially the sensor area, and moisture left in the contacts can lead to oxidation or sensors malfunctioning.
If you are actively involved in sports, it is recommended to have several interchangeable straps. This will allow one kit to dry while you wear another, which will prolong the life of the accessories and preserve the neat look of the gadget.
💡
Regular removal of the cleaning capsule prevents the accumulation of bacteria and prolongs the life of the silicone strap, preventing it from rupturing at places of tension.
