We will look not only at the basic steps (charging, syncing with the Mi Fit application), but also at the typical errors that prevent the successful activation of the device. For example, why the bracelet does not respond to touch after connecting to charging or what to do if the charge indicator does not light up.

If your Mi Band 4 is already lying idle due to failed attempts to turn it on, do not rush to bring it to the service. 90% of the time the problem is solved by yourself in 5-10 minutes, following our step-by-step instructions.
