How to turn on Xiaomi Mi Band smart bracelet: from charging to first synchronization

The Xiaomi Mi Band fitness bracelets have long been one of the most popular wearables thanks to a combination of functionality, compactness and affordable price. However, even with such a simple gadget, users often have questions: how to turn on the bracelet after buying, what to do if it does not respond to presses, or how to properly charge it for the first time.

It is important to understand that the activation process may vary slightly depending on the model (Mi Band 3 vs Mi Band 8), but the general logic remains the same. We will look at the universal steps, and also pay attention to the typical errors that prevent the bracelet from turning on. If your gadget is already lying idle due to a naughty screen, do not rush to carry it to the service: in 90% of cases the problem is solved in 5 minutes.
