For Osmand and Google Nav it also wears the battery down quickly - however, I'm pretty sure this is largely due to the fact that these apps KEEP THE SCREEN ON THE WHOLE TIME. I remedy this by returning to the home screen on long stretches, so that it will turn the screen off, then turn it back on when I'm close to needing direction again.
