I was on wifi at home and headed out in the car. I needed to get an address from an old email and when I tried to retrieve my mail it said there was no connection. I checked to make sure data was on and still nothing. The bars were gray not blue (what does that mean?). I even switched to LTE (as I was on 3G) and still nothing. After 10 mins of this I was about to throw the phone out of the window. When I got home I realized that I had left WIFI on. I am also using JuiceDefender. Would JuiceDefender and WIFI enabled have any issue here? On another note...I am still trying to determine if I want to keep this phone. I am NOT rooted and have had multiple connection issues and the battery life has sucked. I never had these issues with my old DINC (great phone BTW). I am still playing with settings so maybe battery life is MY issue. I think it would almost be a good recommendation to people to not install many apps at first until you get a feel for what the battery can do. I think that FB, Twitter, and others might have been sucking the battery. I have disabled the updates on those to see what happens. And then maybe root... Thanks!
