Query: Nice Features, short battery life

I just got back from returning this phone. I purchased it at the local BJ's for $42, it wasn't worth that. The person I was talking to sounded like they were in a hole and the battery didn't last long at all, probably because of the photo storage and other features. I liked the concept of downloading songs and pictures to attach to callers, but I need it to work well first.
