Bought a 70d 6 months ago. Started out 80% charge getting 215 miles. Once did a 100% and charged to 240. Would go to super chargers occasionally and the first time could not believe how fast and the amperage it was at. Fast forward 6 months and 3 updates and now 80% (daily charge) only gets 204 miles. Daily driving does not even come close to getting the miles as it did brand new. It is a lot colder as we are in the middle of winter and bought the car in the summer (Virginia). Did not realize the heater drains way more than the a/c. Lastly, superchargers..... was in need of a quick charge to get back home from 1 hour away, Got to the supercharger with 100 miles left thinking we could back to 200 in about 20 min or so and the charger would only charge at 26kw. Thought it might be a bad charger so moved over to the next one and same thing, after about 10 min only went to 35kw and stayed there. 8 superchargers and we were the only one using it. - anyone have charging issues after the 8.0 update - is the cold weather that bad on the charging and or daily driving mileage - are others experiencing same super charger issues.
