Since my last routine maintenance, I’ve noticed my car losing charge while just sitting, sometimes up to 3% per day. It stays in an attached garage (40-80°F), so extreme temperatures aren’t a factor. I track my m/kWh closely and recently saw my efficiency drop just from the car sitting. For example, after parking with 82% charge and 3.8 m/kWh, two days later, it was at 79% and 3.5 m/kWh. Even overnight, I lost 1.5% charge and 0.2 m/kWh. Is this normal, or has anyone else experienced unusual phantom drain?
