The higher the temps, the faster the degradation, which is why AZ, TX, HI, and FL Leafs were early indicators. We should know more about the 40KWh batteries after the summer. Bottom line: use and enjoy your EV, but plan on battery degradation.
Its too bad the 80% charging is gone. Would be really interested in seeing side by side of two cars in the Southern tier. One always doing 80% (which is a bit high but close enough) verses one who charges "normally"
Now I have had mine 2 months and 7 weeks of that time was during extreme driving need and I found the range to be sufficient in most cases that it was easy to park the car overnight at 50-70% SOC without range concerns. I did charge to full but most were for range or QC tests with only a handful due to driving need keeping in mind one week I exceeded 200 miles a day 3X.
