An obvious concern with using any electronic device for satellite navigation is the lifetime of the battery, particularly given the high amplification levels needed to use weak GPS signals from space. For mobile phones, there is a cheap solution:  USB "power bank" (external batteries) can be purchased for as little as £5 and are small enough to slip in a pocket.
