Make sure you update the firmware if at all possible. I charged overnight on Wednesday. Thursday I used the phone for 10-15 minutes of calls, took several pictures, showed off the GPS for a few minutes, uploaded a photo to flickr, played some system rush and snakes, watched some videos, and browsed some photos. I still have not lost any bars and it is 8:30 the next morning! My 6682 was about the same, as I had to charge it about every other day. An I had even fitted it with the extended life battery (the one you have to sand the battery door for it to fit). I've definitely noticed a battery improvement with the update.
