The Go v2 has an Auto Power Down (APD) feature. As such the device will power down after 30 minutes of inactivity. However sometimes, when the audio source level is low(eg phone, tablet etc.), the device will register the signal as lower than the APD threshold. This is because the volume on our Go v2 portable Bluetooth speaker is not synchronised to your mobile device(i.e. The two volumes are controlled independently).
To avoid this please ensure that your mobile devices volume is increased to above 50% or more and control the overall volume from your Go v2 speaker.
