I try not to leave my phone plugged in "all the time" - this is the #1 killer of cell phones. Doesn't matter how smart the phone, battery, charger, etc is, charging it all the time shortens the batteries life. Charging it to 100% drastically shortens the life. But that's a different subject.
I use a stand alone GPS as my always on GPS, but I use my phone to navigate to "places". The phone has a much larger and up to date database of places. So I want to find an oil change, or a certain restaurant, or whatever, I ask Google for directions. My phone is fairly new and can run the screen for hours before the battery becomes an issue, so if I need to see the map, I just leave it on. Most of the time the turn by turn audio prompts are enough.
When I drive from one city to another, across 100s of miles, I use the stand alone GPS.
The stand alone gps has a battery in it too, but I don't care about that battery. the stand alone gps is usually turned on when a trip starts and left on until the trip ends.
just my opinions
This whole first paragraph is not correct.
The best thing for your battery is to plugged in at 100%. Phone, laptop and tablet batteries only have so many charge cycles in them. The faster you use those cycles, the faster you use up the battery. Charging from 90% is less of a cycle than charging from 5%.
I use my phone. Truck GPS in terrible. I mainly use Waze. Apple Maps arent very good. Google is pretty decent.
If Im in my vehicles, my phone is charging. To use Carplay I must be plugged in.
