Functionality remains the same between the two versions, though Apple’s vector-based maps do appear more lightweight. AppleInsider tests revealed the Google Maps-powered version transferred some 4 megabytes of data for a single request, compared to just over 400 kilobytes for Apple’s.
Apple stopped using Google Maps beginning with iOS 6. However, Cupertino has continued to use Google’s product through the Web version of iCloud. The switch made today on the iCloud beta site suggests that will soon change.
You can take the new version of Find My iPhone for a test drive by logging into your iCloud account at beta.iCloud.com.
