Is there much of a difference in the battery life of PE5 verses PE 4.*? Right now I am still on 4.2, and I absolutely love it except for one issue. While at work I like to stream radio stations to my BT headset while I work. Now I don't have a problem doing it, but my battery drops from 100% down to as low as 40% while it is still plugged into a wall charger. I just got a new Samsung Galaxy Tab (unrooted) that I have started bringing with me to work and I will do the same with it, but with no battery drain what so ever.
