Why does my Audi e-Tron's battery drain so quickly in cold weather?

I've noticed that during the winter season, my Audi e-Tron's battery seems to drain much faster, even when the car is not in use. Is this common with electric vehicles? Are there any tips or precautions I can take to prevent this decrease in battery life?

It is common for electric vehicle batteries to drain faster in cold weather due to the decrease in chemical reactions and efficiency of the battery cells. To prevent this, you can try to keep your car plugged in overnight and use a pre-conditioning feature if available to warm up the battery before using the car.
