Sorry, there was a problem. Please try again later.if your just playing music the battery should last for over 20 hours, I don't use mine a lot but after 4 weeks I still have half a battery.
Sorry, there was a problem. Please try again later.The one thing I've noticed about this player is the battery stays fully charged a lot longer than my older mp3 player. It seems to be pretty strong. I listen to it pretty long at a time, but not sure about the 5 hours. The battery indicator has only started to go down once and I just hooked up the charger cord to my tv and it seems to charge quickly to full. It has stayed on full ever since that charge. It also charges while I download tunes on my computer. Based on mine, I haven't seen a problem. I'm pleased with that aspect.
