I've spoken with mobile security researchers who have given me the
impression that this theory hasn't been tested very much. It's
theoretically possible that some phones could be recording or
transmitting without the main battery, but the equipment that would be
required to test is prohibitively expensive and you'd have a hard time
demonstrating anything but an evidence of absence.
