Took delivery of my Model LR Y w 20's 13 days ago. Turned on Teslafi a couple days after I got it and 315.04 range reported (close to rated 316). Now, about 10 days later (odometer at under 350 miles), Teslafi reports 311.72 range, a loss of over 1% even after i did a 20% to 95% charge to "balance and calibrate" the battery a few days ago. And I am on the bottom of the Teslafi "fleet" results showing other Model Y cars. Surely i didn't already lose 1% range, did I? I could do another drain to 10-20% and then charge to 90%-95% but don't want to run these deep cycles too often, right? If this doesn't get better and perhaps slips further, maybe ask Tesla to run a battery check? Thoughts, anyone (besides "just relax" LOL).
