Fitness bracelet owners often face the need to replace accessories, whether it is the wear of a standard silicone or the desire to update the design of the device. Xiaomi Mi Band 4 has become a real hit, but its design implies that the main tracker (capsule) is inside the elastic strap. Over time, the material loses its properties, rubs or simply ceases to like visually, and then the question arises about how to safely remove the module.
The replacement process seems simple, but inept actions can damage the case of the gadget or rupture the bracelet itself. In this article, we will discuss in detail all the nuances of dismantling, the necessary tools and precautions that will help you perform the procedure quickly and without consequences for electronics.
Before you start physically affecting the device, it is important to understand the architecture of the attachments. The capsule is held in the pad by the tight fit and special protrusions that are fixed in the slots of the strap, which is a feature of the design that provides protection from moisture and loss during training, but creates difficulties in extraction.
Many users try to tamper with nails or sharp objects at random, which is a mistake. The polycarbonate case from which the module is made is quite durable, but its faces can scratch, and internal electronics can suffer from static electricity or a sharp bend of the board when sloppy pulling.
To start, you will need to prepare a workspace with good lighting and a soft surface so that an accidental tracker does not hit a hard table. It is also recommended to wash and dry your hands, as greasy marks can make it difficult to capture a slippery case.
Workplace preparation and necessary tools
The success of the operation to remove the Mi Band 4 capsule depends on 90 percent of the preparation. You don't need a sophisticated technical arsenal, but having the right tools will make the process much easier and safer for the device.
First of all, make sure the surface you are working on is clean and dry.Dust and fine debris can get inside the strap or onto charging contacts, which will cause problems connecting to the docking station in the future.
There are a few options for tools, and some users prefer to use their fingers, but if you don't have very long nails or sensitive skin, you'd better use foreign objects, like a plastic shoulder blade for smartphone repair or a regular plastic card that you don't mind bent a little bit.
⚠️ Warning: Avoid using metal objects such as knives, screwdrivers or scissors.The metal can leave deep scratches on the tracker body, damage moisture-protective squeezing or, in the worst case, close contacts when carelessly moving.
If you don't have specialized tools at hand, you can use a blunt edge of a ruler, or even a coin of sufficient diameter wrapped in soft fabric, the main thing is that the tool is smooth and has no sharp angles that can tear silicone.

Technique for Safe Tracker Removal
There are several proven methods to pull a fitness bracelet from the silicone base, and the most common and safe way is to hit the bottom of the capsule, where the pulse sensor and charging contacts are located.
Turn the bracelet down, find a notch on the inside of the strap that's exactly the size of the tracker, and carefully press your finger or blunt object on the bottom edge of the capsule, trying to push it upwards, towards the screen.
The movement must be forward and confident, but without jerking, and once one of the edges of the capsule rises above the level of the strap, you can grab it with your fingers and gently shake it from side to side, gradually removing it completely.
If the capsule is very tight, which is often the case with new straps or after long wear, you can use the "scroll" method. Try to slightly twist the tracker around your axis inside the pad to break the tight fit of the walls.
💡
If the Mi Band 4 capsule is not retrieved by normal pressure, place the bracelet on a hard surface with the screen down (putting a napkin on the back) and press the edges of the strap around the tracker on the back.
When extracting, try not to press directly on the sensor itself, so as not to damage its glass surface.
Alternative methods and life hacks
Sometimes standard methods don’t work because of the specific strap instance or the anatomy of the user’s hands, and in these cases, alternative techniques come to the rescue, often discussed in Xiaomi’s owner communities.
One effective way to do this is to use a thin but strong strand or dental floss, and you can thread it under the edge of the capsule on one side, you can loop it around, you can pull it gently, and you can push it back on the strap at the same time, and you can evenly distribute the force.
Another option involves using temperature: Silicone becomes more elastic when heated, you can slightly (literally for a couple of seconds) hold the area around the capsule under a jet of warm water or a hairdryer at a minimum temperature, which will soften the material and make it easier to slide.
- 🧤 Using thin rubber gloves will improve finger grip with the tracker's smooth body.
- 💧 A drop of soap solution at the edges of the lobe will reduce friction, but after the procedure, the device must be thoroughly washed.
- 📏 Plastic card, bent in half, creates an excellent lever for tweaking the edges of the capsule.
- 🔄 The method of rotation (scrolling) helps to loosen the tightly seated module without the use of force.
Some users recommend stretching the strap a little beforehand, stretching it in different directions, which reduces the internal tension of the material, and it is more likely to "release" the object inserted inside.

Compatibility of straps and choice of accessories
Once you've successfully removed the tracker, you're in a world of customization options. The market for Mi Band 4 accessories is huge, but it's important to understand that not all straps are universal.
The fourth-generation capsule design is different from previous models (Mi Band 1, 2, 3) and subsequent models (Mi Band 5, 6, 7).The main difference is the shape of the cutout and the location of the charging contacts. Trying to insert the tracker into an incompatible strap can lead to the fact that it simply does not stand in place or will hang out.
| Tracker model | Capsule shape | Strap compatibility | Features of attachment |
|---|---|---|---|
| Mi Band 3 | Oval, rounded. | Only Mi Band 3. | Leads on the sides |
| Mi Band 4 | Oval, flat back end | Only Mi Band 4. | Tight landing, hidden contacts |
| Mi Band 5/6 | Elongated oval | Mi Band 5, 6, 7 (partially) | Magnetic charging, another form |
When buying a new bracelet, pay attention to the labeling. Often sellers indicate "for Mi Band 4", but there may be universal options with a set of inserts. However, standard silicone, leather and metal bracelets are usually issued strictly for a specific model.
The metal armbands are special, they look stylish, but the process of inserting and removing the capsules from them can be more complicated because of the rigidity of the design. For these cases, manufacturers often provide a special key or make the pawn more open.
Care for the strap and capsule after replacement
Regularly replacing and removing the tracker is a great reason to review and clean the device, and while wearing it, sweat, dust, pile from clothing and skin fat accumulate between the capsule and the strap.
This mixture creates the perfect environment for bacteria to multiply, which can cause skin irritation or an unpleasant odor. So, after removing the module, be sure to wipe the capsule with a soft wet wipe, paying attention to the back panel with sensors.
Charging contacts also require attention. Oxidation or contamination of gold pads can cause the device to stop charging or lose connection to the docking station.
Silicone straps should also be washed. Use warm water with a little soft soap. After washing, dry both parts thoroughly - both tracker and strap - before collecting them back. Moisture inside the pad can cause the screen to fog from the inside or corrosion.
⚠️ Warning: Do not use aggressive chemicals, alcohol solutions or abrasive sponges to clean, which can damage the oleophobic coating of the screen, make the silicone sticky or break the labeling on the case.
If you plan to not use the bracelet for a long time, it is better to store the capsule separately from the strap so that the silicone does not deform and stretch in the places of attachments.
Frequent problems in extraction and their solution
Even following the instructions, users may face unforeseen difficulties, and understanding the nature of these problems will help to avoid panic and breakdown of the gadget.
One of the problems is cracking or crunching when extracting, often the sound of breaking silicone or rubbing plastic against rubber, but sometimes it can indicate damage to the body. If you hear a suspicious sound, immediately stop the effort and examine the device in bright light.
Another situation is that the capsule is removed, but there are pieces of silicone in the strap, or, conversely, sticky glue particles remain on the tracker (if the strap was not original).
- 🛑 The strap breaks under tension: the material has lost elasticity, a complete replacement is required.
- 🔋 Tracker does not charge after replacement: check if it is installed correctly and if it is not flipped.
- 📉 Screen dim or flashing: it is possible that the plume was hit or the display damaged when removed.
In rare cases, there is a production defect, when the size of the capsule and the strap do not match each other. If you bought a new original strap, and the tracker does not fit into it or falls out, it makes sense to check the compatibility of the batches or contact the seller.
💡
The key to success is not to use excessive force. If the Mi Band 4 capsule doesn't come out, you're using the wrong angle or method, not that it's stuck forever.
