The fitness bracelet Xiaomi Mi Band 3 remains a popular device even years after its release - thanks to its reliability, long operating time and wide functionality. However, many users have difficulties when connecting to their smartphone for the first time. Unlike the new models ( Android. Unlike new models (Mi Band 7 or Smart Band Pro), the third version requires a special approach: from choosing the right application to manually setting notification resolution.

In this article you will find not only step-by-step guide for pairing, but also solutions to common errors (for example, when the bracelet is not in the list of devices or is constantly disabled), as well as hidden settings to optimize performance. We took into account all the nuances - from versions Android 10–14 to firmware features MIUI i ColorOS. If you have already tried to connect Mi Band 3 and encountered problems, here you will find the answers.

1. Preparing the phone and bracelet for connection

Before pairing, make sure that both devices are ready for use. Let's start with Mi Band 3:

  • 🔋 Charging the bracelet. Connect it to the charger (use the original cable!) and wait until the charge indicator appears on the screen. Minimum level for connection - 20%, but it is better to charge until 50%.
  • 📱 Phone firmware update. Outdated versions Android (below 8.0) may not support BLE 4.2, which is used in Mi Band 3. Check the software is up to date in Settings → System → System update.
  • 🚫 Disabling VPN and power saving. These features often block apps from running in the background, preventing synchronization. Disable them temporarily.

Also remove old versions of applications Mi Fit or Zepp Lifeif they were installed previously. Residual files may conflict with the new installation. For reliability, clear the cache in Settings → Applications → Storage → Clear cache.

⚠️ Attention: If your phone is running MIUI (for example, Redmi Note 10 or POCO X3), enable permission for application autostart in the security settings. Without this, the bracelet will turn off when the screen is locked.

2. Choosing the right app: Mi Fit vs Zepp Life has officially switched from

Xiaomi officially switched from Mi Fit to Zepp Life (formerly Amazfit), but both apps remain compatible. However, there are key differences: Mi Band 3 both applications remain compatible. However, there are key differences:

Criteria Mi Fit Zepp Life
Notification support Yes (requires manual configuration) Yes (automatic synchronization)
Data synchronization Slower, possible errors Faster, more stable
Interface Outdated, less intuitive Modern, adaptive
Support for third-party services Google Fit, Apple Health Google Fit, Strava, MyFitnessPal

We recommend using Zepp Life for Mi Band 3as it is optimized for new versions Android and is less likely to generate errors during synchronization. Download it from Google Play (avoid third-party sources!). If for some reason Zepp Life is not suitable, Mi Fit will remain a backup option.

Important: When you first start, Zepp Life will request access to contacts i SMS - this is necessary to display notifications. Refusal will result in the bracelet not vibrating during calls or messages.
