Query: no battery life

I love archos, and I love my Gmini 20 GB player, but the battery life is awful!If you have a long commute or you are out and about alot, this player will let you down. I turned the backlighting OFF, and the thing is still constantly running out of juice. I have a short commute, so Ill live, but BEWARE!Also, the seek is slow if you have long sets, and you cannot queue up your next track without stopping the current one.Plusses are it is a no driver needed (XP) filesystem view, which is nice for transferring work files, and it is tiny, sexy cool. I fear for the device when the lithium ion battery performance starts to degrade - I just got it and it sputters after a few hours use!!!
