Owners of popular fitness trackers often face the need to replace a regular accessory, and the question of how to remove the strap from the Xiaomi Mi Band 4 becomes relevant immediately after buying the device. The standard silicone option that comes with the kit can eventually become dirty, lose elasticity or simply stop liking it visually, requiring replacement with a more stylish or functional analog. The dismantling procedure does not require a specialized tool, but knowing the design features of the tracker capsule will avoid accidental damage to the case or loss of precious time in search for a solution.
The fourth-generation Mi Band is radically different from its predecessors, as it uses capsule design, where the tracker itself is completely removed from the frame of the bracelet. This engineering solution makes it easier to replace accessories, but requires accuracy when you first get acquainted with the fixing mechanism. In this article, we will analyze all the nuances of the process, consider possible difficulties and give recommendations for choosing compatible accessories for your gadget.
Design features of the Mi Band 4 fastening
Xiaomi’s fourth-generation fitness bracelet has been completely redesigned from the third version, which has directly affected the strap’s mounting mechanism. The main element here is the main module (capsule), which contains a screen, battery and sensors, and which is now not just inserted into the slots, but removed entirely. The silicone or leather strap in this model is a single frame covering the tracker from all sides, which provides reliable fixation even when actively engaged in sports.
To retrieve the device, you need to understand the way the guides work, which are located on the inside of the silicone frame. Unlike mechanical fasteners, it uses a tight fit like a friction joint, where the friction force keeps the capsule in place, which is why many users are afraid to make an effort at first for fear of breaking the plastic, but the design is designed for regular recovery and installation cycles.
It is important to note that the shape of the capsule Mi Band 4 has specific curvatures that should perfectly coincide with the inner contour of the strap. Using unoriginal or cheap analogues can lead to the fact that the seat will be too tight or, conversely, free, which will complicate the dismantling process or lead to the loss of the tracker during activity.
⚠️ Warning: Never try to nuke the capsule with sharp metal objects such as a knife or screwdriver, as this is guaranteed to cause scratches on the case and can damage the touch screen.
Technical details of the design
Tools and workplace preparation required
While replacing the strap with the Xiaomi Mi Band 4 is positioned as a process that does not require special equipment, properly preparing the workspace will greatly simplify the task. You do not need complex technical tools, but having a smooth, clean surface and good lighting is a prerequisite for comfortable work. Dust and small villi, getting between the capsule and silicone, can create additional friction that makes it difficult to extract.
The best option would be to use a table with a smooth surface, covered with soft cloth or a mouse mat to mitigate the possible fall in parts. If you have a plastic spatula on hand for electronics repair (a spooger), it can come in handy in the rare cases when the silicone is too tight, but in 95% of situations you can do with only your fingers.
- 🧤 Clean dry hands – skimmed skin slides better through silicone and provides reliable grip.
- 💡 Bright light source - allows you to see the gaps between the body of the tracker and the strap.
- 🧼 Soft wipe - for pre-cleaning the surface of the tracker from sweat and pollution.
- 📏 Smooth surface – prevents the loss of small parts in the event of their slippage.
Before the procedure, it is recommended to wipe the tracker itself and the inside of the strap with a dry cloth to remove any moisture or skin fat leftovers.This is not only hygienic, but also technically feasible, since clean surfaces interact more easily with each other. If you plan to install a new accessory, make sure that it is also cleared of factory dust.
💡
Slightly warm up the strap in the palms before removing - the heat will make the silicone more elastic, and the capsule will come out of the landing place with less effort, reducing the risk of damage to the latches.
Step-by-step instructions: how to remove the tracker
The process of removing the strap from the Xiaomi Mi Band 4 consists of several consecutive actions that must be performed smoothly and without jerking. First, take the bracelet in your hand so that the tracker screen looks at you, and the inside of the strap rests on the palm of the other hand or lies on the table. With your thumbs, find the bottom of the capsule, where the charging contact connector is usually located.
The main effort should be to squeeze the module out of the silicone frame. To do this, thumbs press the bottom edge of the tracker on the inside of the bracelet, while slightly pulling it up. The movement should be push-out, not jerk, so as not to damage the plastic case or break the silicone in places of tension. If the tracker does not come out immediately, try to change the angle of inclination or increase the pressure on the opposite edge.
Once one side of the capsule is free, carefully remove it completely, making sure that the screen is not touched with the nails. Some users prefer to first release the upper part and then the lower one, but the classic method of squeezing from the bottom is considered the most effective for the Mi Band 4. It is important to control the force of pressing so that the finger does not slip or hit the hard surface of the table.
☑️ Algorithm of the tracker removal
In some cases, especially if the bracelet has been worn for a long time and the silicone has shrunk or deformed, the process may require a little more effort. Don't be afraid to use moderate force, since the design is built with a margin of safety, but avoid using tools with sharp edges. If you feel that the tracker is stuck, you better stop and try stretching the silicone with your hands, warming it with body heat.
Installation of a new strap: an algorithm of actions
Replacing the old accessory with a new one is a reverse process, which also has its own technical nuances that affect the durability of operation. Before installing, make sure that the new strap is fully compatible with the Mi Band 4 model, since the fourth and fifth generation mounts, as well as earlier versions, can differ in the geometry of the seat.
Once you've fixed the top, gently press the bottom of the capsule into the characteristic click or feel of a tight landing. It's important that the charging contacts are not blocked by the strap material, otherwise you can't charge the device without removing it. Check the density of the fit on all sides: there should be no gaps through which moisture or dust can enter.
| Band type | Complexity of installation | Features of fixation | Recommended use |
|---|---|---|---|
| Silicone (original) | Low. | Tight landing, elasticity | Sports, daily socks |
| Metal (Milanian weaving) | Medium | Hard frame, requires effort | Office, business meetings |
| Leathery | Medium | Soft base, stretched over time | Everyday socks |
| Nylon (loop) | Tall. | Tissue base, may interfere with contacts | Active rest, hiking |
When installing metal or rigid plastic straps, be especially careful, as they are less elastic and can require considerable effort to snap the capsule. Make sure you don't overdo it and break the thin walls of the frame. After installation, check the stability of the fixation several times by slightly shaking the bracelet over the soft surface.
Possible difficulties and ways of solving them
Even with all the instructions, users may face a number of problems related to wear and tear of accessories or manufacturing defects. One common situation is that the capsule is too tightly fit in a new strap, making it impossible to remove it using standard methods. In such cases, you can try to slightly stretch the silicone with your fingers or use the temperature expansion method by placing the bracelet in a warm (but not hot) place.
Another common problem is the loss of the tracker from too stretched or poor-quality strap during active movements. This often happens with cheap counterparts, where the geometry of the inner cavity does not meet Xiaomi standards. If you notice that the tracker sits loose, it is better to temporarily return to the proven accessory or use an additional lock to avoid losing the device.
⚠️ Warning: If after installing the new strap, the sensor has stopped responding or charging is not going, check whether the material covers the frames of the sensors and contact areas.
Sometimes users are faced with a situation where the silicone strap begins to turn yellow or crack in the places of fold. This is a natural aging process of the material under the influence of ultraviolet light and skin fat. Regularly washing the strap with warm water and soap will help to prolong its life, but if there are microcracks, it is better to replace the accessory to prevent a complete rupture and loss of the tracker.
💡
The quality of the strap’s execution directly affects the safety of your tracker: cheap analogues may not ensure proper fixation of the capsule, which increases the risk of losing the device.
Choosing compatible accessories and caring for them
The wearable electronics market offers a wide variety of options, from simple silicone replacements to complex titanium engineering designs. When choosing a new Mi Band 4 strap, pay attention not only to the look but also to the quality of the material the inner frame is made of. Cheap silicone can have an unpleasant smell, sticky surface and quickly lose shape, which will make wearing the device uncomfortable.
To care for the strap, it is recommended to wipe it regularly with a wet wipe, especially after sports training, when sweat remains on the surface.The salt contained in sweat can aggressively affect certain types of coatings and metals, causing corrosion or color change. Periodically remove the tracker and wash the strap itself under running water using soft soap.
- 🚿 Wash silicone straps with warm water after each workout to remove sweat salts.
- ☀️ Avoid prolonged direct exposure to sunlight to prevent fading and destruction of the material structure.
- 🧴 Do not use aggressive chemical solvents or abrasive cleaning products to clean the surface.
- 🔄 Change the strap at the first sign of material destruction to avoid losing the tracker.
When buying, pay attention to the feedback of other users regarding the compatibility of a particular model of the strap with the Mi Band 4. Some manufacturers may claim versatility, but in practice the fit may not be ideal. It is better to choose a specialized accessory designed specifically for the fourth generation to be sure of the reliability of fixation and moisture protection of the device.
