i keep having this problem too! i just bought this stupid thing, and i turned it off yesterday with maybe 1/5 of the battery drained, and then i turn it back on not even 5 hours later, and all the power is COMPLETELY gone! i couldn't even get to the menu. i also have a problem with the screen that comes on after awhile (you know, the clock and the battery indicator?) where the battery indicator ALWAYS shows a larger depletion than the other one. not only that, but when i first turn on my ipod and choose a song, i can feel the hard drive cranking and the menu's get very slow. actually, the menu's get slow if i don't touch the click wheel for awhile too, and the pictures get stuck on the screen and stuff. VERY ANNOYING. i hope they fix this, or i will just have to return it, it really is a rip-off.
