If someone told you that iOS 6 Maps had one advantage over Google Maps, and that it was 80% more efficient in using data, you’d probably quip, “That’s because it’s 80% less accurate” then do an air drum roll and punctuate the whole thing with the sound of a cymbal crashing that you made with your mouth.
Joking aside, though, it’s true. iOS 6 Maps uses way less data than Google Maps, and it has nothing to do with accuracy, but with its beautiful new vector graphics.
