After using Remote S (now officially "Remote for Tesla") for years, I just today discovered that when no charge cable is inserted it shows the current and total usable charge levels in kWh as one of two alternating messages at the bottom left of the lower car-status display. For my 85D, for trip planning I've been using 73 kWh as my estimate of usable capacity. Remote S is today showing 72.7 kWh as its estimate.
