Not good news if you have a Model S 85... Tesla owners see battery range drop after software update to 'improve longevity' - Electrek
Tesla owner David Rasmussen got one of the most severe drops we have seen so far. He told Electrek: “My 2014 Model S 85 was getting Rated Range of 247 miles until May 13. Now after the next update, it continued to drop to now 217 miles. This is an 11% drop in 5 weeks.” Rasmussen has been plotting the battery capacity degradation of his Model S over the last 100,000 miles or so and the recent drop is quite obvious:
He went to his local Tesla service center with the issue and like most other owners reporting the same issue, he was told that is “normal degradation” of the battery pack. That’s surprising because previous data showed that Tesla’s battery degradation is limited to less than 10% after over 160,000 miles. We contacted Tesla about the issue and the company confirmed to Electrek that the range reduction is due to the software update. Tesla told us that the goal of the update is to “protect the battery and improve battery longevity” and it resulted in a range loss for only “a small percentage of owners.”
