Hey, i recently bought a sony nw-hd3 from a sony shop and am happy with it so far. I have read a few of the forums about charging the player a few times and letting the battery fully run out etc and have done all that, yet i seem to be getting nowhere near the 30 hours battery life! My files are 64kbs and i only seem to be getting 10 hours or less! I heard maybe charging the player with the usb cable attached to the computer as well fully charges it, (but i tried doing that and it took over 5 hours and still was not fully charged) and that only using the ac charger charges it only 80% can someone please help???!!!!
