Why does my BMW i3 have lower than expected range?

I recently purchased a BMW i3 and noticed that its range is significantly lower than the advertised range. What could be causing this issue and how can I improve my range?

The range of your BMW i3 can be affected by various factors. One common cause for lower than expected range is extreme temperatures, both hot and cold. Extreme heat can reduce the efficiency of your car's battery, while very cold temperatures can cause the battery to lose its charge more quickly. It is recommended to park your car in a garage or shaded area during hot days and to pre-condition your car before driving in cold weather.
