How to encourage users to provide a more precise position

I use my iPhone’s GPS geotag for virtually all my observations. I have no idea how it calculates the accuracy bubble, but I do notice that it is wildly variable even when the pinpoint is accurate. I don’t often check the accuracy bubble when I submit an observation, so I seldom know what it is. Of course if someone asks me about a specific location I check it, and I shrink the bubble if that’s appropriate. But my point is that I don’t think most people are controlling the accuracy estimate when they submit.
