No matter what i do, my phone dies within ten hours. I am not alone in the crappy smartphone battery department. So such measures are beyond workable for those of us too broke to afford a decent phone. I had to get a portable charger battery so i can review a gps app!

It will all be pointless anyway, if scuttlebutt i hear is true. Search teams will become nothing but recovery teams, since satellite advances will make it possible to zoom in and scan for critters in any terrain and identify them accurately. Not even a need for boots on the ground at that point.
