I usually play my mini in Shuffle Song mode and my battery life is lousy. After completely charge up the mini and play shuffle song for an hour, I will have about 80% battery left. During play, I don't touch the mini to change songs or anything. Also, EQ and Sound Check are both off. My normal practice is 2 hours use per day and I will have to recharge it every two days so I am getting only ~4 hours of battery life on this new mini.
Is this normal or I should visit an Apple repair center?
Thanks for your input.
