At first, yes. I got about 4-5 hours. I read some of the messages and attempted to calibrate it. What I did to do this was ran the battery completely down, until there is no sign of life, when I came back to the nano, all I saw was the apple icon. I then charged it for 2-3 or until the battery life indicator indicated full. I then got 13 27 minutes. I am now getting 8 hours at this minute and the battery inidcator is still 1/4 lit up. I would try this at least once and maybe a second time, just drain it all the way, you will see a difference. Also, make sure that your backlight is kept low ( 2 seconds or so )and the EQ is turned off or set to the flat mode. You will see a big difference..... Good Luck.....
