New owner here. Charged my car and drive to work. I got out of the car and it had 203 miles on it. Checked it at lunch still 203 miles and after work went down to drive home and got in the car and now it has 199 miles. I lost 4 miles in eight hours. I was fine. I still had 199 miles but I’m just wondering if this is normal so I can factor it into my charging plans. TIA.
