Owners of Xiaomi fitness trackers often face the need to replace the regular strap. This can be due to the wear of the old silicone, the desire to diversify the appearance of the gadget, or the need for a more sporty or classic design. Despite the apparent simplicity of the design, the process of removing or installing the module (capsules) has its own nuances, ignoring which can lead to breakage of the device or injury to the fingers.
Modern models such as the Mi Band 7, Mi Band 8 and Smart Band 8 Pro have different mounting mechanisms that differ from earlier versions. Incorrect mounting effort often causes body deformation or damage to charging contact areas. In this article, we will discuss in detail how to safely replace the strap on your model, what tools you may need, and how to avoid typical errors in the maintenance of wearable electronics.
Before you start mechanically impacting the device, you need to make sure you understand the design of your version of the tracker. The mounting design ranges from simple grooves to complex push-button mechanisms. If you act too aggressively, you can damage the moisture protection or the capsule body itself. Let's look at the basic stages of preparation and the replacement process.
Design features and preparation for work
The first step before any manipulation is to determine the type of attachment of your device. Most Xiaomi models, from the first generation to the Mi Band 6, use the classic scheme: the capsule is a convex oval that is inserted into the strap slot from the bottom up or side. However, with the release of the Mi Band 7 and especially the Mi Band 8, the company has introduced new types of attachments, including magnetic and hinge systems.
It's important to understand that the silicone strap loses its elasticity over time. The old material becomes stiff and tight, which makes it much harder to install a new capsule. If you change the strap on a device you've been wearing for several years, be prepared for the fact that it takes more effort than when working with a new accessory. The elasticity of the material plays a key role in the ease of installation.
- 🔍 Visually inspect the strap grooves for cracks or sprains that may weaken the fixation.
- 🧼 Carefully wipe the capsule body and the inside of the strap with an alcohol wipe for degreasing.
- 🌡️ Make sure your hands are dry and warm as cold silicone becomes stiffer and brittle.
Some users try to use sharp objects, such as knives or scissors, to tweak the capsule. This is strongly discouraged. Sharp metal can easily slip and scratch the screen, damage the touchpad or, even worse, punch through the battery case. It is better to use plastic cards or special tools to open electronics if standard methods do not remove the tracker.
⚠️ Warning: Never use metal screwdrivers or knives to slap a strap capsule. high risk of damaging the screen or impairing the tightness of the case, resulting in loss of water protection.
Workplace preparation is also important. It's best to replace a table with a soft coating, such as a towel, if the capsule slips out of your fingers during installation, the soft surface will prevent scratches on the glass or body, and the hardened glass of the screen, while strong, can get microcracks when it hits a hard corner of the table.
Instructions for Mi Band 1, 2, 3, 4, 5 and 6 models
Classic fitness bracelets have the most common type of attachment, and they have an oval or pill shape and they fit into the strap on the bottom side. To remove the tracker, you have to push it out of the seat. On the bottom of the strap, under the capsule, there's often a small recess or slot designed for that.
To put the capsule back in, you need to match the rounded edges of the body with the cutouts in the strap. First, one side is inserted (usually the top or bottom, depending on the design of the particular strap), then the capsule is forcefully snapped into the grooves. Fixation occurs by tensioning the silicone. It is important to hear or feel the characteristic click or tight fit.
The installation process takes a lot of effort. Don't be afraid to push, but do it evenly, spreading the pressure across the surface of the capsule, not the center of the screen. Pressure on the display can damage the matrix. It's best to push your thumbs on the back of the tracker and the side faces.
☑️ Checking the installation of the capsule
If the new strap is too tight, you can warm up the silicone a little. Warm water or a hair dryer (at a minimum temperature and from a safe distance) will make the material more malleable. This will make it easier to insert the capsule and reduce the risk of breaking the strap at the place of least resistance - at the edges of the slot.
Replacement of the strap on the Mi Band 7 and newer versions
With the release of the Mi Band 7, the design has changed, and although the principle has remained similar to previous generations (inserting the capsule into the slot), the shape of the body has become more rectangular with rounded corners, and the dimensions have increased, the straps from previous models (1-6) do not fit into the seventh version due to the difference in the dimensions of the capsule.
The Mi Band 7 strap also uses a push method to remove the module, and the inside of the strap has protrusions or indentations, and if you press your finger or blunt object, you push the capsule up, and when you install the new capsule, it's important to properly orient it, the touchpad should look up, and the charging contacts should look down, towards the wrist.
- 📏 Make sure you buy a Mi Band 7 strap, as the dimensions are different from previous versions.
- 🔄 When installing, monitor the orientation of charging contacts so that they are not closed by the strap material.
- 💪 Use uniform pressure when latching so as not to skew the module in the seat.
A common mistake is to insert the capsule sideways, the seat design involves moving strictly perpendicular to the plane of the strap, and lateral pressure can break the thin silicone lintels, and then the strap becomes unusable because the capsule will fall out when moving.
⚠️ Attention: Don't put too much effort into the capsule if the capsule doesn't come in. Check for correct orientation and no foreign objects in the strap slots.
Specifics of mounting Mi Band 8 and Pro versions
The Mi Band 8 and 8 Pro are very different from their predecessors, and they use a completely new mounting mechanism that allows you to turn the bracelet into a pendant or a shoe mount. The Mi Band 8 capsule does not fit directly into the silicone slot, as in the older models.
In these models, the capsule has special metal protrusions on the sides. To fit into the classic silicone strap (which comes with a package), you first need to attach the capsule to the plastic holder, and this holder is put into the holes of the strap, a normal watch. Or, depending on the type of strap, the capsule is inserted into special slots from the ends.
To remove the Mi Band 8 capsule, you have to press the special locks or compress the frame, and then the module is released. It's a more complex mechanism, which requires accuracy. The metal contacts here are more open, and it's important not to bend them when you sloppy replace. In the Pro model, the mechanism is similar, but the size is much larger.
Owners of the Mi Band 8 should be especially careful when buying third-party straps. The market is flooded with accessories of varying quality. Cheap copies can have poorly cast plastic mounts that will not securely fix the expensive capsule. There is a risk of losing the tracker if the fastener suddenly unbuttoned during training.
Installation problems and ways to solve them
Even following the instructions, you can run into difficulties. Often users complain that the capsule falls out of the strap or, conversely, does not stand up. One common reason is the stretching of the strap. Over time, the silicone stretches, and the seat becomes too wide, in which case the capsule will dangle and may fall out.
Another problem is contamination of contacts or grooves. Sweat, dirt and skin fat create a sticky layer that prevents a tight fit. Regular cleaning of Settings → System → Reset (if it's a software bug) won't help, you need physical cleaning. Wipe the inside of the strap and the tracker body.
| Model | Type of attachment | Difficulty replacing | Risk of damage |
|---|---|---|---|
| Mi Band 4-6 | Insert in the slot | Medium | Medium (scratches) |
| Mi Band 7 | Insert in the slot | Medium | Medium (scratches) |
| Mi Band 8 | Special frame/holder | Low. | Low. |
| Mi Band 8 Pro | Special frame/holder | Low. | Low. |
If the capsule falls out, you can try to slightly reduce the diameter of the strap at the mounting site by warming it up with a hair dryer and compressing it (although this is a temporary measure). A more reliable way is to buy a new strap. Accessories are low, and the risk of losing the tracker is not worth it. Security of fixation is the number one priority.
Care for the tracker strap and capsule
To extend the life of the accessory and the device itself, it is important to properly care for them.Silicon tends to accumulate dust and pile.Rule the strap regularly with warm water and soap.It is also useful for the hygiene of the skin of the wrist.The capsule can also be washed, but avoid soapy water entering speakers (if any, like in the Mi Band 8) or microphones.
Avoid contact with aggressive chemicals such as alcohol, acetone, solvents, which can make silicone cloudy, sticky, or even break its structure, and alcohol-based antibacterials are acceptable for quick wipes, but not for long soaking.
- 🚿 Remove the bracelet before applying creams, lotions and perfumes on your hands.
- ☀️ Do not leave the device under direct sunlight, ultraviolet light destroys the structure of the polymer.
- 🔄 Periodically change the side of wearing or loosen the strap so that the skin "breathes".
If you notice that the silicone has started cracking at the base of the capsule, immediately replace the strap. The cracks tend to grow quickly, and at one point you may find that the bracelet is dangling on your arm and the tracker is lost. Timely replacement of the worn strap is the cheapest way to keep your Mi Band.
⚠️ Attention: If you experience irritation or redness of the skin under the strap, stop wearing the device. Give the skin a rest and treat the injury.
