An efficient trip will have you charging to 100% when charging overnight, and to less than 80% in Superchargers along the way.
This is because charging speed will taper as your get closer to full.
You will get a note on your display if Tesla determines you have been charging higher than is good for your battery. You can adapt another strategy at that point.
I travel on business from Flagstaff, AZ to Phoenix and back about three times a month. Airline trip and the car is parked for 4 days usually.
2017 S100D.
Due to the altitude change, you can't make it round trip even if you leave Flagstaff at 100%.
I charge to 100%, drive the 154 miles to PHX, using about 125 rated miles. Parked for 3-4 days at the airport I lose several percent due to vampire loss; more when it's really hot or really cold in PHX, due to the BMS cooling or heating the battery while parked.
I stop at Cordes Lakes Supercharger, which is almost exactly halfway back. I usually have about 30% left. I only need to charge for 5-6 minutes to be able to drive fast uphill to Flag and still have 35 miles in reserve.
If I left the house with less than 100%, I'd have a longer charge at Cordes on the return.
