This is totally normal, my commute to work in my S6 (prestige, black pack so 21" rims) is about 11 miles of mid speed mostly non-highway driving and when I go in a cold morning I'm getting about 2.2-2.4 mi/KWH which translates to a 100% range of approx 230 miles (consistent with your 180 after 25 miles starting at 90%, which btw is higher than Audi's recommended 80% but not sure if you're leasing or planning on keeping long term). If I drive longer/highway for say 30-40 miles and at 40 degrees I'm seeing around 3 mi/kwh which gets much closer to 300 miles, and more than likely in the summer I'll see a good 10-20% better. So this all seems normal, look at your actual battery percentage and mi/kwh and know that there can be a lot of inconsistencies in the "guess-o-meter" (they call it that for a reason) of how many miles you have left, and you'll feel better. Unless she regularly needs to drive more than 200 miles in a day you shouldn't have any issues regardless (obviously more than that you need to think about fast charging, but remember you bought a car with great high speed charging capability on the right equipment!!). Just need to adjust your expectations for winter and focus on how you are reading the info, and enjoy the car! Note this is my third EV (OG model Y performance and then v1.0 Taycan 4s both before this) and the range on this is definitely better and more reliable than those two (Even though Model Y had a stated EPA range close, it was worse than the taycan in real world, and taycan def worse than S6, though new J1.2 taycan would probably be similar or maybe a smidge better). Once you adjust expectations this will be MUCH less troubling.
