Yes, if you're in a city you're tracked constantly by dragnet surveillance.

Questions like this one aren't very useful without a threat model. Who are you trying to prevent tracking you? If it's just your phone carrier then obviously turning off your phone and removing the battery will render it inoperable. But now you don't have a phone, and your location info wasn't very useful to begin with anyway unless you were involved in an operation where you need to conceal your location.

A patron was telling me that the way the GPS is so accurate is because it uses the phones radio... Didnt know that either. (i mentioned to him that there is one spot in MA where our google directions are off by 1/2 mile.. Same place every trip.)

It's called Assisted GPS: https://en.wikipedia.org/wiki/Assisted_GPS

It speeds up getting an accurate location, doesn't provide a more accurate location than GPS.

GPS on is generally accurate to around 5 or 6 metres. That's the technology on it's own.
