I find that in standby the phone is good for about 6 days, listening to music for about 7 hours a day it'll last about 3 days.
If you talk a lot, it'll be a lot less. I get about five hours talk time with mine.

Mine seems to last 3-4 days depending on how I use it. It has an amazing standby time though so if you're not very popular it will last all week.;)
