I wonder if at some point phones will have built-in maps to the nearest (sponsored, naturally) charging location, to plan our routes like electric cars can do.

It's not built-in to any devices or sponsored by anyone but OpenStreetMap already has a tagging scheme for phone charging stations: https://wiki.openstreetmap.org/wiki/Tag:amenity%3Ddevice_cha...
