Sound link Color II Disconnects/stays paired
I have Bluetooth paired my Soundlink Color II to Windows 10 laptop, as well as my LG Stylo 4 phone. The pairing work good and stays paired. When I want to listen I connect, at which time the voice prompt report battery status and which devices are connected. I listen for a while and then stop listening. I leave and come back 30 minutes later and the device has disconnected. It is still paired, only I need to connect again. Is this normal? Should the connection stay active until I explicitly disconnect?
