Don't suppose anyone knows the trick to make sure it's really turned off and not just "sleeping" (where it still seems to suck the life out of the battery even though you're not listening to anything)? Sometimes when I think it's off, it really is (I see the apple logo come on the screen like it's powering up) but other times.... that battery with it's "14 hour" life seems to last me only a few days of 2-3 hours use per day, max. confused
