Why Xiaomi Smart Watches Don’t Connect to Android and How to Fix It

Xiaomi smartwatches and fitness bracelets are some of the most popular wearables on the market due to their combination of price, functionality and compatibility with Android. However, even with such proven gadgets, users often face problems when connecting the device for the first time: the application does not see the device, synchronization is interrupted, or the watch refuses to update. In this article, we will analyze all the ways of connecting – from the standard procedure through Mi Fitness to alternative methods for older models.

It’s important to understand that the process can vary depending on the watch model (e.g. Mi Band 7 vs Xiaomi Watch 2 Pro), the Android version (starting with Android 8.0 requires permission to access notifications), and even the device’s firmware region.

If you've already tried to connect your watch and you get an error like "Device failed" or "Synchronization failed" - do not rush to reset the settings. 80% of the time, the problem is solved by updating the firmware or changing the region in the application settings.

What Xiaomi Watches are compatible with Android

Before connecting, make sure your watch model officially supports sync with Android. Here is the current list of devices (data for 2026):

  • πŸ“± Mi Band Series: from Mi Band 3 to Mi Band 8 (including Mi Band 8 Pro)
  • ⌚ Xiaomi Smart Watch: Xiaomi Watch, Watch S1/S2, Watch 2 Pro, Watch S3
  • πŸ”΄ Redmi Watch: Redmi Watch 2/3/4, Redmi Watch 2 Lite
  • πŸƒ Fitness bracelets: Xiaomi Smart Band Pro, Mi Band Lite (limited functionality)

Note that some models (e.g. Xiaomi Watch S1 Active) require firmware updates via Mi Fitness before first connecting, and Chinese versions of devices (with CN firmware) may not support Russian in the interface, but data synchronization will work.
