It's been 5 months since my original post so I figured it'd be a good time to post an update to this data. Plus, the weather has turned warmer for the season so the winter decline in Batt Kapa Max seems to be over for this year.Same disclaimers from original post apply (not a random sample of data, one car only etc.).And to highlight the new data since last post, here is the past 5 months only. The trends are definitely flatter and even upward in graph #2 and #4 which is very likely due to the warmer weather being on the right side.At this point I am seriously considering taking the car in to ask BMW about the capacity because recent months of Batt. Kapa Max readings have mostly been below 13.1 (which I calculate to be the 70% warranty threshold--anyone please correct me if they know/ suspect otherwise).Additionally, the "Electrified" app shows my battery State of Health at 68% which both lines up with what the Kapa Max reading shows and is also below 70% last time I checked.Anyone have any thoughts/ recommendations on whether I should do that or not? I realize I'd have to pay for the test if it passes, but I also feel pretty strongly that the capacity is below the 70% warranty threshold (even if just by a few percent)
