Sorry, there was a problem. Please try again later.I suspect volume plays a big role in battery life. If you turn up the volume on your source it may help as you can turn the speaker volume lower. Of course this means your phone/mp3 player will lose juice faster. I have played mine for at least 4 hours at a crack with no weakness in volume and no charge required.
