Does the Assistant listening for OK Google destroy your battery life?

Your phone reads sensor data as a base state.

The Google Now only listens for the trigger phrase when idle - which is done all locally, without needing to talk to the servers.

It has a battery impact but much less than sending all the voice data continuously to a server somewhere. The biggest battery killer would be the wifi or 3G transmitting non-stop in that case.

It wouldn't have to transmit non-stop -- it could do some parsing/cleanup locally, then queue it up and upload it periodically with other, expected FB traffic.

Not really. These have hardware dsp support. The drain is minimum.
