I rarely turn it entirely off, since it takes an annoyingly long time to start back up again, but it stays in silent mode most of the time. I don't use email sync, either, and I leave location services disabled unless I'm about to launch an app for which I think location services would be useful. Basically I want the phone to sit there and do nothing until I decide I want something from it.
