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.
