Why is my BMW i8's electric range decreasing?

I noticed that the electric range of my BMW i8 is decreasing over time. What could be causing this and how can I improve it?

One possible reason for this could be the battery aging. As batteries age, their capacity decreases, resulting in a lower electric range for your car. It is important to properly maintain and care for your car's battery to prevent this decrease in range.

Another reason could be the way you are driving your car. Hard acceleration, constant high speeds, and frequent braking can all contribute to decreased electric range. Try adjusting your driving habits to be more efficient and conserve battery power.
