That depends on how you use the car. I live in Montreal and charge at home, so on my daily commute, I plug in overnight every ~10 days in summer and in winter, every ~7 days. That makes absolutely no difference since it takes 10 seconds to plug in. On road trips, yes, you need to stop more...
Keep in mind the "range" indicator is an estimate (many of us refer to it as a guess-o-meter, or GOM). The estimate is based on many things including past driving habits, weather conditions, some AI algorithm reading tea leaves and other magic. The true measure is what you actually got from driving.
