Why is the range of BMW iX shorter than advertised?

I recently purchased a BMW iX and was disappointed to find that the range was significantly shorter than what was advertised. What could be causing this and how can I improve the range?

The range of an electric vehicle can be affected by various factors such as weather conditions, driving style, and the use of accessories like air conditioning. In order to improve the range, try to minimize the use of these factors and stick to more efficient driving techniques.
