Recently my battery percentage has been going down 1 every few months. MX June 2018 started at 208 miles at 90% now it’s at 203 miles at 90% my last known 100% was 222. What are your range looking like at 90-100%? In the first few months of having the car I only charged it to 80%. For the past 4 months, I started charging it to 90% and since then it has gone from 206 to 203 at 90%. Should I be worried? I rarely go below 20% maybe only 5 times max and 100% 4 times. SC about 75 times. When I first got the car it was at 228 100%. What are your thoughts? Let me know.
