Buying the Xiaomi Mi Band 4C is a great choice for those who want to track activity, sleep and health at no extra cost.

If you skip even one step, the Mi Band 4C may not display the time, not synchronize data or even turn on, we will tell you how to do it right the first time, and we will give tips for fixing possible problems.

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

Before you turn on the Xiaomi Mi Band 4C, make sure you have everything you need to set up successfully.

• 📱 Smartphone on Android 5.0+ or iOS 10.0+ (The bracelet does not support older versions).
• 🔌 Outlet charger 5V/1A (Charging from the phone is fine, but it is better to use the original Xiaomi adapter).
• 📲 Installed Mi Fit app (you can download it from Google Play or App Store).
• 🔄 Stable Internet connection (for downloading firmware and synchronizing data).

Pay special attention to smartphone compatibility. If your phone is Released before 2015, there is a high risk that Bluetooth 4.0 (the minimum version for working with the bracelet) is not on it, you can check this in the phone settings in the About Phone → Bluetooth version.

Also, you should turn off the energy-saving mode on your smartphone in advance - it can block the background work of the Mi Fit, which makes the bracelet unable to sync. On Android, this is done in Settings → Battery → Power Saving Mode, on iPhone - in Settings → Battery → Low Power Mode.
