Lr Rwd 1mi Decrease Every Day

[Lemonpie889]

My LR RWD has been decreasing in its max 90% charge every single day by one mile for several days now. It used to be 290, but then it dropped to 289, then 288, and 287. This has happened every single day. I've heard of old s and x's experiencing recent changes to max battery charge due to tesla's battery improvement measures but not with model 3's. This started happening recently, and I am on 2019.20.2.1.

Anyone have any ideas or experience this?

Yes. If you let the battery get down to about 15%, then charge to 100%, you will most likely see the miles increase again. The BMS recalibrates and provides a more accurate reading. The “miles” number is not exact, but an estimation based is battery voltages which is not an exact science when the pack is not balanced. Charging to 100% balances the pack. Just make sure you don't let the car sit a long time at 100%.

Several days does not make an statistical history on a battery. Just chill, the world isn't ending. For battery degradation, measure it a few times a year, not daily.

I’m actually not worried about degradation. I only have 7k miles on the car. I thought it was just quite strange that the 90% battery soc was dropping 1 mile consistently for several days, like it was being recapped.
