I did notice it drain a lot if you keep it pluged all the time to the computer with sonicstage on for a long time. But once you're done with editing/check-in/out, the battery meter goes up a bar or 2 agan in playback. :? Anyway , I give it a minute rest and plug it again and my baterry is good again for a few more edits :roll:
