A staggered rollout is underway that brings an option to make Maps download data primarily over -Fi. If you have the feature (I was unable to see it even with the latest A) you’ll find a prominent -Fi only toggle in the settings menu.  There’s also a small popup box that will tell you a small amount of data will still be used with this enabled, but far less than if you were downloading everything over a cellular connection. Some are also seeing a Subway Status setting that would let you get “real-time disruption alerts” when there’s a delay on your local mass transit. Since this is an issue with pretty much every single system out there, it should be welcomed with open arms. If you want to give these new features a try, make sure you have version 9.32.1 of Maps from the ay Store or A Mirror. You may need to be patient, as these features aren’t showing up for everyone yet; it may be a staged rollout, or just limited testing. The impact on you: Maps can be a data hog, so the -Fi setting may save you from running over your plan’s limits. On the other h the mass transit notifications can be a lifesaver in a city, giving you an excuse to grab a cup of coffee on the way home instead of getting frustrated by trains that aren’t going to show up.
