Please refer to the manual for diagram/explanation but:
If the iDSD is linked to the USB port before turning on it will be in USB Power/Desktop mode use USB Power to charge/top-up charge the battery all the time - the DAC and analogue stage still run directly on the Battery though, but the battery is maintained at optimum voltage by the charger.
If the iDSD is turned on before being linked to a USB port it is in Portable/Battery mode and USB power is disconnected internally. In this case and if the battery is discharged and if the USB Port can supply enough current to charge (meaning not iPhone, iPad, iPod or'droid phone) the iDSD will revert to USB Power/Desktop mode transparently or if no charge current can be drawn and the battery is flat it will shut down until it can recharge.
As the batteries used do not age due to cycling either way of doing things is fine. The battery is fully-protected against over discharge and overcharge, inherently.
