I am getting about 8hrs, thats with 3G & bluetooth on. With a normal amount of use. If I turn the 3G off and use only the edge and wifi for internet, making sure to disconnect after use and and with the brightness down one block. I am on day 2 1/2 right now with about 1/8 of the battery left. Thats with about 1 hour of 3g and 1 hour of wifi (making sure to change back to gsm after use), 1 hour max of mp3's, and maybe 20-30 mins of phone use. I have no active widgets.
