Why is the BMW iX's range significantly lower than the advertised range?

I recently purchased a BMW iX and have noticed that the range I am getting is significantly lower than what was advertised. I have been using the car mostly for city driving and I expected to get a similar range as the advertised range. What could be causing this and how can I improve my range?

The advertised range for electric cars is usually based on ideal driving conditions, such as highway driving with consistent speeds. In city driving, there are more stops and starts, which can affect your range. To improve your range, try to avoid sudden accelerations and plan your routes to avoid traffic.

Another factor that can affect your range is the temperature. Cold weather can decrease an electric car's range, so if you are driving in colder climates, try to use the car's pre-conditioning feature to warm up the battery before your trip.
