The Xiaomi Mi Band fitness bracelets have long been popular with users due to a combination of functionality and affordable price. However, many people face difficulties when first trying to remove an electronic capsule from the strap - whether it is to replace the strap, clean the device or repair. The manufacturer does not always pay attention to this point in the official instructions, which leads to the risk of damage to the latches or the body itself.
In this article, we will discuss three proven ways to safely remove the module from the bracelet for Mi Band 3-8 models, including nuances for each version. You will learn what tools you will need (and how to replace them at home), how to avoid the typical mistake of breaking plastic locks, and what to do if the capsule is stuck in the strap.
Important: the procedure is different for classic straps and metal bracelet versions (for example, Mi Band 7 Pro or Mi Smart Band 8 Pro). If you have this model, skip the first two methods and immediately go to the section about metal bracelets.
Why would you need to remove the capsule from the bracelet?
At first glance, it seems far-fetched to have to take an electronic module out of a strap, but in practice, it's more common than you might think.
- 🔄 Replacing the strap is the most obvious case: Xiaomi straps wear out in 6-12 months of active use (especially silicone), and metal bracelets can rub the skin.
- 🧼 Deep cleaning: Under the capsule, sweat, dust and dirt accumulate that cannot be removed without being completely removed, which can irritate the skin or cause sensors to malfunction.
- 🔧 Repair or diagnostics: If the bracelet is not charging, synchronizing or "glutching", the first thing to check the contacts under the capsule.
- 📦 When sending the bracelet (for example, when selling), the capsule is often removed to avoid damage.
In addition, some users modify their Mi Band by mounting the capsule in straps from other manufacturers (such as Amazfit or Huawei).
