I took delivery 3 weeks ago, and have been tracking usage using TeslaFi.com for the last 2 weeks. At delivery car had 2018.14.7 and spent vast majority of the day in Sleep losing very little (15-20 hrs of Sleep / loss of 1-4 mi per day). After 2018.18.1 software update car has not slept but has been Idle instead losing a lot more (15-20 hrs of Idle / loss of 14-22 mi per day). After 2018.18.2 software update situation remains the same, with large Idle losses. Any ideas? Only TeslaFi has API access to the car, no settings have been changed.
