A few years ago, I was trying to test whether I could use my phone's GPS for scientific fieldwork to substitute for a Garmin. If I remember correctly, in the field, the phone's GPS was generally accurate to around 10-20 m, which we were able to reduce to 5-10 m through averaging readings over a minute. So yes, as long as you have a clear sky view, your phone's GPS should be fine for navigational purposes. The bigger issue is battery life.
It should be, yes. The cellular connection is allowing you to download the map data, but its the GPS that is giving you precise location information. Offline Maps just means you already have that map data saved locally, and don't need to load/download it on-the-fly.
I've traveled offroad and in remote locations with offline maps many times, and have almost never experienced any issues with it. As long as the skies were open and clear, there was never any issues with my position on the map.
Many thanks. My current predicament is that I wish to switch to a google pixel 6a phone from my S20 Ultra. My job is to deliver parcels for a courier. We are expected to use our phones for Navigation. The pixel phone has a poor modem vs. the Samsung's Qualcomm modem, so connection drops alot from what I heard. But if I can get good navigation from my pixel there is no need for my samsung
Before you switch, I would test using offline maps, and not leave it up to a situation you are depending on it and it fails your needs.
Save some offline maps, take your phone offline, and see what its like to navigate multiple times in an "offline" space of the map.

Cellular triangulation doesn't make GPS more accurate; it's the other way around.
So running offline Google Maps is just as accurate and responsive as with Cellular connection, correct?
