Why does the Bluetooth suddenly disconnect while using the Redmi Buds 6 Play?

The earbuds suddenly disconnected from the phone.
The reasons for the problem are as follows:
1. The earbud battery is low;
2. The phone is too far away from the earbuds, exceeding the effective transmission distance (10m), or obstacles are blocking between the earbuds and the phone;
3. Due to the special nature of Bluetooth earbuds, electromagnetic waves in your area will interfere with Bluetooth connections.
To resolve the above problems, please refer to the following methods:
1. Please charge the earbuds immediately;
2. Put the earbuds together with the phone and reconnect them;
3. Please confirm if your earbuds are in an environment with strong interference, away from objects with significant electromagnetic interference such as microwave ovens and surveillance cameras.
If none of the above can solve the problem, please try restoring the factory settings. Press and hold the button for 10 seconds, and the indicator will flash. Reconnect to restore the factory settings.
