As you can see from the above comparison chart, like its predecessor, the Mi Band 3 does not come with a physical On/Off button. Its operations are completely through the companion app that you will have to download and pair.

How to Turn On Mi Band 3

The Mi Band 3 that we received did not have any charge out of the box. The only way to turn it on is by connecting the charging cable attached to a USB port. See the screenshot below:

Once there is a reasonable amount of charge (say 5%) on the band, you will be able to pair it with your phone if it’s the first time. To turn on the Mi band, 3 follow these simple steps:

  • Charge the device to at least 50% before pairing it for the first time.
  • Use the charging cable to force the band to turn on

Turning Off the Mi Band 3

The device is designed to be worn all the time for constant heart rate monitoring. Therefore, it does not come with a physical On/Off hardware button. So, to turn it off, we suggest the following:

  • Allow the battery to drain over time to turn it off.
  • Using the “Find your device” drains a lot of battery.

If you were already using the Mi band 3 on another device, do ensure to unpair from the original device first. If you try to unpair the device when the Mi Band 2 is not in range, it will result in a split-brain scenario.

It will lead to the device being removed from the software App only. Whereas the Mi band 3 will still think that it is paired with the original device. This is when you would need to do a hard reset. Ensure to remove the device only when it is in standard BlueTooth range.

Resetting the Mi Band 3

Option 1:

  • Force stop the “‘Bluetooth Share process” by going into Settings>Apps>Under Running Apps
  • Remove any Data that is cached in the process
  • Go to your BlueTooth settings and select the Mi band and tap “Forget Device.”
  • Reopen Mi-Fit App and pair the device from the beginning.

Option 2:

  • Unpair the Mi Band 2 from within the Mi-Fit App
  • Remove the device from your Phone’s Bluetooth settings by selecting “Forget Device.”
  • Remove any cache files or data stores in the Mi-Fit App from Settings>Apps
  • Uninstall and Reinstall the App from the Google Play Store.

Answering Phone calls on the Mi Band 3

On the ‘Mi-Fit‘ app, when you tap on your paired device, you get device-specific settings. See below:

You can toggle the “Incoming Call” option based on your preferences. There are no more granular options available. Also, you will have to remember, that the band does not sync with the phones “Silent” or “DND” settings. You will have to set this up in the app manually.


We hope our article helped answer your questions about the Mi Band 3. Since the band is 95% operated via the App, it is imperative to set all the options diligently. Once you have set up your preferences, you should have a smooth ride after that.
