The HTC's Aria cellular phone seems to be able to be used as an MP3 player. Depending on frequency of usage as far as games, calling and texting, as well as music playing, the battery life will reflect that.

In my opinion, I think what makes an MP3 player better than any other is a touch-screen and or good sound quality. Another thing that makes an MP3 player better than any other is good battery life and good wi-fi.
You either plug it in to the charger, or replace the battery.
well most obviously, charge the battery and turn on the mp3 player, if it doesn't turn on it's most liky dead, housever you should use a multimeter to check the actual battery. well most obviously, charge the battery and turn on the mp3 player, if it doesn't turn on it's most liky dead, housever you should use a multimeter to check the actual battery.

plug 1 end of the usb in the mp3 and 1 end in the computer
