How to turn on the fitness bracelet Xiaomi Mi Band 3: from charging to the first launch

The Xiaomi Mi Band 3 fitness bracelet remains one of the most popular trackers even years after its release, thanks to its reliability, long run time and wide functionality. However, new users often have difficulty with the first turn on: the bracelet does not respond to pressing, does not charge or connect to the phone. In this article, we will discuss all possible ways to activate the Mi Band 3, including solving typical problems.

It's important to understand that the switching on process depends on the current state of the device: whether the battery is dead, whether the bracelet has been previously paired with another phone, or you just unpacked it out of the box. We'll look at each scenario separately, and we'll give you recommendations on how to choose a customization application (Mi Fit or Zepp Life) and optimize the bracelet after the first run.

Preparation for the first turn on: what to check before activation

Before you try to turn on the Mi Band 3, make sure that the basic conditions are met. Often users miss these steps, which makes the bracelet seem "unworkable."

• 📱 Install compatible app: Mi Band 3 works with Mi Fit (version 4.6.0 and higher) or Zepp Life (formerly Amazfit). Download one from Google Play or the App Store.
• 🔄 Update your phone’s firmware: Older versions of Android (below 5.0) or iOS (below 10.0) may have connection issues.
• 📶 Turn on Bluetooth and geolocation: without them, synchronization with the bracelet is impossible. iPhone also requires you to allow access to Notifications for the application.

If the bracelet has been used before, it can be blocked by binding to another account, in which case you will need to reset to factory settings - how to do this, read the corresponding section below.

Method 2: Initiation after prolonged downtime or discharge

If the Mi Band 3 had been idle for months, its battery could have gone into sleep mode, in which case the standard charging connection might not work.

1. Use "hard" reset: Connect the bracelet to charge and hold the touch button for 20-30 seconds. The screen should go out, then turn on again with the Mi logo. This signals the exit from sleep mode.

1. Connect the bracelet to the charger.
2. Hold the touch button for 15-20 seconds until the screen goes out and turns on again.
3. Release the button and the bracelet will reset.
