How to turn on Bluetooth on Xiaomi Mi Band: instructions for all models

Why Bluetooth on Mi Band doesn’t work out of the box and how to fix it

The Xiaomi Mi Band fitness bracelets have long been synonymous with affordable and functional smart electronics. However, many users face the paradox of buying a device and it refuses to connect to a phone via Bluetooth. The reason lies in the architecture of the gadget - the bracelet does not have a physical button on / off the module. Bluetooth is activated automatically when you first pair with a smartphone, but only if all the conditions are met.

In this article, we will not only discuss the standard connection procedure, but also consider the hidden settings in the Mi Fitness application that affect connection stability. For example, few people know that the Energy Saving feature in some firmware disables Bluetooth background mode, which causes notifications to arrive with a delay or do not come at all, and you will learn how to wake up the bracelet if it stops responding to connection attempts after the update.

It is important to understand: the activation algorithm of Bluetooth is different for Mi Band models 4/5 And the newer Mi Band. 6/7/8 (including the Mi Smart Band 8 The latter support the Bluetooth protocol. 5.2 It's power-efficient, but it requires an updated Zepp Life app (formerly Mi Fit) and if you're trying to plug the bracelet in with an older version of the software, it might just "not see" the device.

Preparing for Connection: What to Do Before Turning On Bluetooth

Before you try to activate Bluetooth on the Xiaomi Mi Band, make sure that the basic requirements are met. Without them, even a perfectly working bracelet will not be able to connect to a smartphone.

• 📱 Update the app: For Mi Band 6/7/8 Use Zepp Life (download to Google Play or App Store) Older versions of Mi Fit don't support newer models.
• 🔋 Bracelet charging: Battery level should be at least 20%.When discharged below this threshold, the Bluetooth module goes into deep sleep mode.
• 📶 App permissions: In your smartphone settings, give Zepp Life access to: 📍 Geodane (for accurate tracking of activity) 📱 Bluetooth and associated devices 🔔 Notifications (to make the bracelet vibrate when calling)
• 🔄 Reboot devices: If the bracelet previously connected to another phone, reset via Settings → About the device → Reset.

Pay particular attention to the operating system versions on your smartphone. For example, the Mi Band 8 Pro requires Android 8.0.+ or iOS 12.0+. On older versions, Bluetooth may be connected, but some features (e.g., fast data synchronization) will not be available.

Standard procedure for turning Bluetooth on the Mi Band

If the bracelet is new or has been reset to factory settings, the Bluetooth activation takes place in two steps: activation on the device itself and pairing with the smartphone.
