Replacement of the strap on Xiaomi smart watches: instructions with photos and tips

The strap on Xiaomi’s smartwatch is not just an accessory, but an important part of the device that affects wear comfort, sensor accuracy and even appearance. Over time, even the best bracelet wears out: rubber cracks, silicone loses elasticity, and metal fasteners begin to catch. Fortunately, you can replace the strap on most Xiaomi Watch or Mi Band models yourself in 5-10 minutes without resorting to a service center.

In this article, we will look at all the steps of the process, from choosing the right strap to fixing a new bracelet, and also talk about the nuances that will help avoid errors. For example, did you know that the wrong material can distort the pulsemeter data? or that some Xiaomi models require a special tool to replace? If not, read on.

We tested the instructions on popular models: Xiaomi Watch S3, Mi Band 8, Xiaomi Watch 2 Pro and Redmi Watch 3 Active. All the steps are universal, but for rare versions (for example, Xiaomi Watch Color 2) additional actions may be required - we will mention them too.

1. Which strap is suitable for your watch?

Before you buy a new bracelet, make sure it is compatible with your model. The width of the mount is the main parameter: most Xiaomi Watch it is 20 mm or 22 mm, and the fitness bracelets Mi Band – 18 mm. Check the size with a rod or ruler, measuring the distance between the ears of the mount on the body of the watch.

The material of the strap affects not only the appearance, but also the functionality:

• 🧴 Silicone is the most popular option for the sport, hypoallergenic, not afraid of water, but can stretch over time.
• 🏃 Tissue (nylon) – breathable, suitable for long wear, but absorbs sweat and requires washing.
• 💎 Metal mesh is a premium look, but heavier and can rub the skin with active movements.
• 👔 Skin (natural/artificial) - stylish, but not for exercise (fears moisture and sweat).

Importantly, magnetic fasteners can interfere with the heart rate sensor, and if you notice inaccurate pulse readings, try replacing the bracelet with a classic one with a buckle.

2. Replacement tools: what will be needed?

For most Xiaomi models, it is enough to have:

• ✂️ Flat screwdriver (or special tool for removing straps - sold in watch repair kits).

• 📏 Line or bar - to check the width of the fastening.
• 🧴 Alcohol wipes – to clear the grooves of dirt before installing a new strap.

Warning: Do not use a knife or scissors instead of a screwdriver - they may scratch the watch body or damage the fastening mechanism.

3. Step-by-step instruction: how to remove the old strap

The process varies depending on the type of mounting. Xiaomi uses three main mechanisms:

1. Spring pins (most Mi Band and Redmi Watch)
