Was hoping someone could help me out here. I've noticed that if I'm using Google Music and/or Google Maps Navigation my battery continues to drain even if it's plugged in. It's rather frustrating because I like to listen to music and I also like to keep my eye on traffic during my commute home. It's even more frustrating that it drains even if it's just music! I had a 1A charger that I used with my old Droid Incredible for years without any issue. I thought that maybe with the 4G I needed some more output so I went out and purchased a 2.1A car charger. It doesn't seem to make any difference at all. I'm still seeing the same battery drain rate. I thought maybe it was thinking the chargers were usb (as a 500mA charge would definitely be insufficient) but as far as I can tell it believes it's plugged into a wall charger. Does anyone have any ideas? This is extremely frustrating!
