i run garmin XT, google maps, and now amaze for GPS. i used XT to go from my house 6 hours to hubert, Nc with no porblems. i used the car charger the whole way. one thing you have to remember is if the phone gets hot it stops charging and once you hit 100% it stops and doesnt start again unless you unplug and plug back in. one thing i do is if im not using the phone while its on the car charger is i turn the screen off. if you dont hit the power button the screen is still on even though its dimmed. wifi and data are always off unless i need to check the weather or use google maps and i have the long press setup to turn data off. so once im done i disconnect from data. thats the best way i know of to keep the battery life as long as i can.
