I just upgraded from wicked sensations last series. I am an over the road driver and I use google maps constantly. I leave my phone plugged in and the screen live all day long. No issues. Since I upgraded my google maps now can not keep up with the power demand, I slowly discharge even though I am plugged in. I am not sure if this has something to do with the new series rom or something else in my phone. If anyone has ideas please let me know. This is kind of critical to me.
