Short battery life | SoundTouch® Portable series II Wi-Fi® music system
The battery will lose some charge while not in use.
While the system enters into a standby mode after 20 minutes of inactivity when disconnected from AC power, the IR receiver on the system is still active in order to respond to commands from the remote. The system will remain in this standby state for eight days before it enters battery protection mode. A small amount of power loss will occur during this standby state, while the system reboots and when re-activating Wi-Fi functionality. Because of this the battery level indication may display a lower level of charge than previously checked.
