Yes.
When I have the app running, with my typical (moderate/heavy) usage levels my phone lasts somewhere between 11-14 hours. When the app doesn't run I get about 5-7, maybe 8 hours with the same usage.
Suffice it to say, that there have been times when I've noticed my battery draining at an unusually fast rate and have realized (and then noticed) its because the JuiceDefender app wasn't running.
