I was hoping someone could help me as I'm using Google Maps to keep an eye on live traffic and have the screen timing out. Annoying when I have security on the phone and have to keep putting my pattern in while driving. Any options besides removing security or extending the time? Also, can someone give a definite answer whether or not WIFI drains the batter faster? Should I be using WIFI at home as opposed to 3G for optimal battery life? Thanks in advance!
