Hello... I had my EVO in for repair and got it back (after 20 days) on 8/3 when 2.2 was released and update my phone. Today, I decided to try out the Google Navigation for the first time on the phone since the 2.2 update and return from repair because it appeared that the Navi app had been updated during my long repair. Anyway, with the phone PLUGGED INTO MY CAR using Google Navi in conjunction with whatever other service the Navi needs (GPS, Google Maps, etc) plus my "basic settings" (brightness around 25%, email sync for 5 accounts ever 30 minutes, my weather apps running) the battery ***WAS NOT GAINING CHARGE WHILE PLUGGED IN***!!!!! I am essentially RUNNING IN PLACE while plugged into the car :-/// MY reading of this issue is that the phone was using the battery AS FAST AS the car charger was charging the battery. Before my 2.2 update I was using the SAME phone with the SAME charger WITH Google Navigation and my phone WOULD increase charge (albeit slowly). I do NOT have the specs on the charger that I am using in the car but my ASSumption is that the "charging power/rate" (layman's term) for the charger is just NOT ENOUGH to keep up with the battery consumption while using Navi and everything else while in the car. Can anyone guide me as to whether my above theory is right?? Can someone suggest MINIMUM "specs" for a car charger so that I actually experience my battery CHARGING in the car and not just "running in place"?? THANK YOU!!
