There are a number of ways of extending battery life. With the Geotag Photos Pro app, you can select the frequency with which your position is tagged--every 30 seconds, every minute, etc. Reducing the tagging frequency substantially increases battery life. Another option, which will give the greatest battery life, is to have the app tag your position only when you tell it to. Hence, if you spend a long time at the same location, you only tag once, whereas if you're moving around, you can tag each time you change position.
