What's eating battery charge the most is the display. It would be best to install a power outlet and use the car charging cord while continuously running any phone as a GPS. But then it's best to run power to a dedicated GPS as well, even in a car or truck.
If you just take the phone out when you stop to get your bearing, then the battery should last a bit longer. It would still be better if you could charge it while riding, or while camped at night.
