Of note - this seems to read “actual” battery capacity available - the one piece of the puzzle that I couldn’t get access to when using efficiency in mi/kWh to determine range. I always had to assume 100% of battery spec was available. Apparently I have 78 kWh available from 79kWh capacity, just a hair below the 81.2 kWh spec.
Anyway, including some screen grabs for you battery egg-heads out there.

Is this equivalent to iphone battery health? My phone battery health typically drops off dramatically after the first year (below 95%) but I'm not careful about optimum charging. Would the same be expected for i5/550e batteries but probably after 30-40k miles or so?
