Step-by-step: how to connect Xiaomi Mi Band 3 to a smartphone in 2026

Xiaomi Mi Band 3 remains one of the most popular fitness bracelets even years after its release, thanks to its reliability, long work time and wide functionality. However, many users have difficulties with the first connection of the device to a smartphone, especially if it is a used gadget or changing the phone. In this article, we will analyze all the current ways of synchronization (including bypassing typical errors), and also tell you how to set up notifications, pedometer and pulsemeter after connection.

It’s important to consider that since 2023, the official Mi Fit app has been replaced by Zepp Life (formerly Amazfit), but Mi Band 3 is still supported in both apps, although the functionality in them is slightly different. We tested both options on Android 13/14 and iOS 16/17 – the instructions below are relevant for all modern versions of the OS.

1. Preparation of the bracelet and smartphone before connection

Before you start syncing, make sure your Mi Band 3 is ready to go.

  • πŸ”‹ Charging the bracelet: Connect the bracelet to the charger (magnetic connector) and wait for the charging indicator to appear on the screen. Minimum level for connection is 20%, but it is better to charge to 50%.
  • πŸ“± Phone compatibility: Make sure your smartphone runs Android 5.0+ or iOS 10.0+. On older versions of the application may not be installed.
  • 🌐 Internet connection: To download the application and synchronize data, you will need stable Wi-Fi or mobile Internet (3G/4G/5G).
  • πŸ”„ Reset bracelet: If the Mi Band 3 was already in use, reset to factory settings (press the touch button for 10 seconds until vibration appears).

Also check if the phone is on:

  • πŸ“Ά Bluetooth (required!)
  • πŸ“ Geolocation (required for accurate weather display and some features)
  • πŸ”” Notifications for the Zepp application Life/Mi Fit (in the phone settings).

⚠️ Note: If you use an iPhone, turn off the β€œTracking Limit” function in your privacy settings before connecting (Settings) β†’ Confidentiality β†’ Geolocation services β†’ Otherwise, the bracelet will not be able to synchronize location data for weather.

2. App selection: Zepp Life vs Mi Fit - which is better for Mi Band 3?

Xiaomi has been gradually moving all wearable devices to the Zepp Life platform (formerly Amazfit) since 2023, but Mi Fit is still working with the Mi Band 3.

FunctionZepp LifeMi Fit
Support for Mi Band 3βœ… Yes.βœ… Yes.
Interface.Modern, with an emphasis on healthOutdated but familiar
Synchronization of dataFaster, fewer mistakes.Sometimes it hangs.
NotificationsFlexible customization for each applicationLimited options
Firmware updatesβœ… Automatic.❌ Only manually.

We recommend using Zepp Life for new users, as the app is being updated and offers more opportunities for health analysis, but if you want to use the familiar Mi Fit ecosystem (for example, to sync with Mi Home), you can stay on it. Both apps are free and available on the App Store and Google Play.

How do you know which app is already installed on the bracelet? When you connect to Zepp Life, the bracelet will suggest updating the firmware if you have previously used Mi Fit. That's fine - agree to an upgrade.

If you already have one of the apps installed, be sure to delete the bracelet from your account in the first application before switching to another. Otherwise, synchronization conflicts may occur.
