I only charge to 100% when I have to take a trip besides this past week when I was trying to see how much battery capacity was lost since I picked it up at Tesla. A loss from 212 to 190 which is a 9% loss in less than a week. I haven't tripped charged it again since then but am curious to see what it is now. Just FYI, I normally charge to 90% or less for the past 5 years.
Beyond the recent trip when it cut out at 139 miles, what were the longest trips and kWh usage before that? And to confirm, what was the SOC at the start of that trip (and the others). This data will help determine the actual pack capacity, otherwise the only metric is the estimated range which could be underestimating the true degredation.
(Apologies if this data is present in the preceding 20+ pages)
