After having a HD5, what have Sony done with the NWA3000, after a full charge i only have to select a playlist or a few songs and it drains a bar out of the battery!!! , i use to charge my hd5 once a week and it never went below a bar on the battery, but this thing you only have to put the disply up and it saps the juice!!, i have everything to minimum, but it still saps like crazy, if i listen with my display remote from my mini disc player it saps even quicker, i shouldnt need to charge it once a day? what am i doing something wrong? Your thoughts please????
