Vampire drain higher when battery is low?

    I didn't have time to charge much last night. I had enough range to get to work and then to a local L2 charger at lunch so I could at least get all the way home after work.

    I arrived at work with 28 miles left. When I got in the car at lunch I had 18 left. I looked at my teslafi and I lost 10miles of range in about 90 minutes because the car didn't go directly into sleep mode like it usually does. So 30 minutes of my charging at lunch was just to "get back" the miles I lost this morning.

    I've noticed this a few times already so it doesn't appear to be a one-off scenario. It's like my car turns into the person that panics and eats all of the food in an emergency situation. Has anyone else noticed a significant increase in vampire drain when the battery gets low?

    Sounds like teslafi is preventing the car from going to sleep.

    That doesn't seem to be the case any other day. It's usually the opposite. As soon as I get out of the car, it falls asleep nearly instantly. Some days it takes ~30mins, but I only have 0.37-0.74mi of loss when that happens, not 10 miles in 90mins.
