Maybe test a new charging routine. Rather than cycle between 70 and 90% SOC, try something radically different, like 50 to 70%, and then charge up higher for weekends, if you plan to go somewhere.My car shows 230 miles at 90% and around 256 at 100%. Tesla said over the app that my battery is fine and that the car is underestimating my range. If i wanted to fix it, they suggest letting battery go down to 5% and the. Charge to 100%. Then going forward, I should let battery drain to 15-20% before charging back to 90% and it will fix itself over time. I haven’t tried that and just continue to charge from around 70% back to 90% daily.
