I've got a new job that most of the day i'm in an area that doesn't get signal. I've noticed i don't lose a lot of battery life, but when i go to area's that have some signal and the phone seems to be flipping between no data, and data, as well as finding signal and losing signal my battery drains like i'm chugging a beer. I downloaded juice defender free version, but i'm honestly at a loss with it thinking i need a paid version. The location also has a wifi connection that i can connect to. Any advice on how to save battery life without having to shut the phone off, and turn it on when ever i go outside would be great.
