I've only had my D2G for four days, but so far I am extremely surprised (disappointed) with the battery life. I welcome any and all suggestions on how to improve it. I just installed BatteryFu, and it looks like it will help - if anyone has suggestions on how to best tweak that app, I'd love to hear them. I need all email and SMS to come through, and I also need my SIP client active at all times during working hours. Thanks.
