Connecting smartwatches to Xiaomi Redmi 9: full instruction with tips and life hacks

Smartwatches have become an integral part of everyday life β€” they monitor health, display notifications and even replace the wallet. But to make all these functions work, you need to connect the gadget to the smartphone correctly. Owners of Xiaomi Redmi 9 often face the nuances: the app does not find the watch, the synchronization is interrupted, the battery goes down too quickly. In this article, we will analyze all the stages of connection, from choosing a compatible application to setting up notifications, and also tell you how to avoid typical errors.

The Redmi 9 is powered by MIUI, Xiaomi’s proprietary shell, which sometimes blocks the background activity of apps to save power. It can interfere with stable communication with the watch. Also, not all smartwatches are equally well-compatible with budget smartphones. We tested the instructions on the Mi Band 6, Amazfit GTS 2 and Haylou Solar β€” all of which have successfully connected, but with different nuances. If you have a different model, don’t worry: synchronization principles are universal.
