From the recently released 4GEE Mobile Living Index which analyzes mobile data use and 4G trends on the EE Network (a British carrier) in the U.K. since 2013:
Traffic on the new Apple Maps now represents 70% of mapping traffic on the 4G network, from 60% in the second half of 2013, taking market share from Google maps, which is down 7ppts. This difference is even more marked over 3G where Apple Maps is up 19ppts and Google Maps is down 15ppts.
EE may push iPhones over Androids so this doesn’t necessarily mean this data applies to all carriers across the board, but every day Apple Maps is getting better and every day thousands of people get a new phone with Apple Maps pre-installed. Apple Maps is for real. You might want to pay attention to it.
