Why is the BMW iVision's battery range less than expected?

I recently purchased a BMW iVision and noticed that the battery range is not living up to its advertised capabilities. What could be causing this discrepancy?

There could be a few reasons for this. One possibility is that you are not utilizing the regenerative braking system effectively, which can significantly increase your battery range. Another factor could be your driving habits and using features like air conditioning or heating, which can drain the battery quickly.
