Question for anyone running a tablet for navigation.
How's your battery life?
I sometimes use a GPS app on my smartphone, & a half-day trip will just about kill the battery, even with the phone plugged in to charge the whole time

Apparently, phone's aren't intended to have the screen turned on continually & it's the display that eat's battery power.
