I would guess that the Garmin takes into account the altitude change to do a better estimation of distance - i.e. going up an incline looks like a shorter distance is covered; the phone will likely not be sampling as frequently, so curves are treated as straight lines sometimes - all resulting in what appears to be less distance.
How do either compare with a cheap bike computer though? Do you find the Garmin is better than the bike computer calculating speed and distance from the tires revolutions?
