2018 Mazda 3 Sport Hatchback. I have a dash cam connected to the car charger in the center arm rest. The light on the car charger stays on even after turning the car off and locking the doors. Even coming back after 10+ minutes the light is on. This is the second dash cam that I've tried, and both do the same. Does this mean it's drawing power from the battery even after the car is off?

 

Yes...
