So I finally switched about 2 months ago to a 3GS from my BlackBerry Bold and I am SUPER DISAPPOINTED with my battery life. I cannot even get through 1/2 of the day without needing to plug in to the car charger. This is my second iPhone - the first one was swapped b/c of the battery. I would say average use (15-20 sms, 40 min of phone, and 10-15 min of web) during this time. Does anyone have any suggestions before I decide to switch back to my BB?
