Why is my Kia Soul's battery draining quickly?

I noticed that my Kia Soul's battery is draining quicker than usual. What could be causing this issue and how can I fix it?

Make sure all electrical components are turned off when the car is not in use. This includes dashboard lights, radio, and interior lights.

Check for any loose or corroded battery connections. If necessary, clean and tighten them to ensure a secure connection.

It could be a malfunctioning alternator. Consider having it checked and replaced if necessary.
