Query: terrible battery life

This is a very comfortable headset and was quite easy to set up with my Motorola phone. The sound quality is as good as other headsets I've used, and people on the other end of a call have told me that my voice is clearer. However, I'm VERY disappointed with how poor the battery life has been. I get less than 1 hour of talk time and less than 48 hours of standby time. I could go over a week with my old Nokia bluetooth headset.
