I have a 85 RWD and 90D and I have noticed that my 90D has twice the degradation of the my 85 with HALF the miles. At 42k miles I am approaching 10% degradation, while my 85 has been consistent at 3% the last 30k miles. My 85 regularly charges to 232 miles at 90% (rated new at 265) while my 90D is currently at 241 miles at 90% (rated at 294). Chatted with Mary at Tesla support, she told me I could have a HV battery diagnostic on my car and stated range is dependent on how we drive (SMH). I tried to explain "rated" miles, but there was no hope for her. Are the 90D's that bad? I have tried to balance the battery pack / charge 100%, but it has no impact on range short or long term.
