I’ve got a 2013 P85 with 52k on it. Recently I’ve noticed the range when battery at 100% has dropped significantly, and all of the sudden. I’m not positive but it seems to coincide with the V9 update. The car used to charge to 251 miles at 100%, and suddenly is only charging to 211 miles. I’ve tried fully discharging and recharging several times and I’ve made sure the setting is correct for displaying the range. I’ve tried charging on home charger and supercharging and there is no difference. Has anyone else experienced this, and does anyone know if this is enough degradation to warrant a battery replacement? Thanks everyone!
