The Xiaomi Mi Band 4 fitness bracelet remains one of the most popular trackers even years after its release, thanks to its combination of affordable price, reliability and wide functionality. However, new users often have questions about how to properly turn the device on, connect it to a smartphone and adjust basic parameters. In this article, we will analyze the activation process by steps, from unpacking to first synchronization, and also consider typical errors and how to fix them.
Itβs important to understand that the Mi Band 4 works in conjunction with the smartphone through the official Mi Fitness app, without which the bracelet will not be able to reach its full potential: sleep tracking, call notifications, heart rate monitoring and other functions will not be available, and the activation process itself takes no more than 10-15 minutes, if you follow the instructions and take into account several key nuances.
Preparation for activation: what to do before turning on the bracelet
Before you start setting up the Xiaomi Mi Band 4, make sure you have everything you need, which will eliminate unnecessary problems such as incompatibility of the smartphone or lack of the right cable.
First, check your phone's compatibility. The bracelet works with Android 5.0 devices.+ or iOS 10.0+. If your smartphone is older, the Mi Fitness app may not install or function with errors. Second, prepare the charger: complete with the Mi Band 4 comes a special cable with a special device. USB-You can't plug the bracelet directly into the socket, just through an adapter or a computer.
- π± Smartphone on Android/iOS current-only
- π Charging cable from the set (or compatible analogue)
- π² Mi Fitness app (download in advance from Google Play or App Store)
- π Charge at least 20% on the bracelet (at first switching on)
Also worth considering that Mi Band 4 was released in several versions: standard (XMSH08HM) and NFC-version (XMSH09HM). The latter supports contactless payments, but requires additional configuration in the bank application. If you purchased a bracelet with NFC, check whether your bank supports this function (for example, in Russia works with Sberbank Online, Tinkoff, etc.).
β οΈ Warning: If you bought a used bracelet, reset to factory settings before activation. To do this, press the touch button on the Mi Band 4 screen for 10-15 seconds until the vibration and the Mi logo appear.
Step 1: Charging the bracelet before first switching on
The new Xiaomi Mi Band 4 usually has a minimum battery charge, which is only enough for the first turn on.To avoid a sudden shutdown during setup, it is recommended to fully charge the device before use.
For this:

- Connect the magnetic charging cable connector to the back of the Mi Band 4 body. Contacts should match - you will hear a slight click.
- Connect the cable to USB-computer port, charger (5V/1A) power bank.
The charge indicator will appear on the bracelet screen, a battery icon with animation. Full charging takes about 1-1.5 hours. The optimal level to start setting is at least 50%, but it is better to wait for 100%. If the bracelet does not respond to the cable connection, check:
- π Clean contacts (wipe them with a dry wipe)
- π Correct connection (magnet must fit tightly)
