Does anyone know if the eTron's battery charge drops when it is not in use or being charged? And if so, how much does it drop each day? We parked our eTron at airport parking and it will be there for a week. We keep checking the mileage range from the Audi app and it has not changed in 2 days. We are not sure if it doesn't discharge at all while parked or if the Audi app isn't connecting to the eTron since it hasn't been used for 2 days. Does anyone have any experience with this? I would think that the mileage range would drop perhaps 2-5 miles per day when it is just sitting in long term parking.

I bet you're not the only one. Some engineer commented on the E-Tron's battery specs saying its "off" and raises questions.

Symptoms like this might be the result of what he's talking about.

Mileage range drops less than 2 miles per day when Audi is parked

So my wife parked the eTron at airport parking for six full days. When she left it, the range showed 163 miles. When she came back, it was down to 153 miles. So the miscellaneous electrical activity that happens when the car is parked drains less than 2 miles from the range every 24 hours. That is better than I expected.
Interestingly, I kept checking the range from the Audi app and it showed 163 miles for all six days. So it didn't seem as if the Audi app was able to obtain the mileage range when the car was parked during those six days.

I think you might actually want to limit your check to what the car reports as % of remaining battery capacity simply because range is recalculated dynamically based on driving habit and terrain (i.e., here in Seattle, going up our 3 block long, 20+% grade knocks 3-5 miles off of the range consistently even though distance traveled is more like about 0.3 miles.

That said, I'll see what happens when we leave the car off the charger while we are gone over Thanksgiving holiday weekend and see what the level of battery usage is over those 3-4 days.
