If the Xiaomi Bluetooth Speaker Essential automatically plays music, please refer to the following methods for troubleshooting:
1. If your device has previously been paired with the speaker, a connection record will be saved. When Bluetooth is enabled, your device can automatically reconnect to the speaker and start playing the audio from the device.
2. When your speaker is not turned off, it can be connected to other devices by others and play audio.
3. Check whether the music or media application on your device has the auto-play feature enabled, as some apps automatically resume playback when a Bluetooth audio device is connected.
4. To prevent this issue, you can turn off Bluetooth when the speaker is not in use, disconnect the speaker from previously paired devices, or power off the speaker after use.
