As far as "the battery being dead", that seems to be a never-ending argument among the anti-cell-phone folks on here (not that you are one of them)... It really is simple, carry an external battery. Most do these days on long trails I would think, lots of choices out there, fairly light these days, a couple of phone charges for 5 ounces or so (like the Anker 6700 maH, or 10,000 mah, about 6 ounces). Keep you cell inairplane, navigate very, very accurately, and you're good to go for probably 10 days before recharging. I bet a modern cell with 4.7 ounce Anker battery is not much, if any heavier than a Garmin stand alone gps with its extra set of batteries.
