There is a setting in the JBL One app called Bluetooth reconnection. You can change the behavior to enable it to automatically reconnect every time the speaker is turned on, if this is the behavior you want.

The speaker has an auto calibration feature, which measures the space around the speaker and adjusts the sound quality based on the room around it. Auto calibration will automatically work when you power on the speaker and begin playing music. For the best sound, we recommend placing the speaker in the middle of the room, at least 0.5 meters away from any walls.

When not connected to AC power, the speaker will be automatically switch off after 1 hour of inactivity to save battery consumption. You can adjust the auto standby time on JBL One app.

If your Micro II does not sense an audio signal on its input, it goes into Standby to save power. It should wake up again when audio is sensed. Since Micro II senses audio on its input, not on the speaker volume, always turn up the volume on the source, then control speaker volume on the Micro II. This way it will not go into Standby unless music stops.

Please check your OS version. If you are using an iPhone with OS version of 8.3 or lower , please upgrade your system to the latest version.
