Why is the range of my BMW i3 decreasing so quickly?

I recently purchased a BMW i3 and noticed that the range is decreasing much faster than expected. Can anyone explain why this is happening and how I can improve the range?

There can be several factors that affect the range of your BMW i3, such as weather conditions, driving habits, and use of power-consuming features. It is important to monitor your driving habits and try to make small changes, such as using eco mode and planning your route to include charging stations. Also, make sure to regularly check your tire pressure and use regenerative braking to prolong the range.
