I have posted this 100 pages ago but I'm a model 3 owner and my battery capacity went from 100% at 20something k miles to a 8 or 9% loss from June to August/September around the time of that software update. A lot of other model 3 owners are seeing the same especially AWD owners as we didn't get the bump to 325 miles. My battery has since recovered to 6% degradation.
Anyways I'm guessing they did something to the BMS as it is odd that I got 100% all winter and started seeing degradation in the summer. Tesla says my battery is fine and blames it on the warm weather but I'm in Canada and the weather really wasn't that warm.
I'm not saying that you guys don't have a capping issue but without seeing the voltage at 100% you really don't know if it's just degradation or capping, which is why I posted my scanmytesla data. You both may just be experiencing degration or the effect of temperature changing.Same boat as you. I've lost 2.34 miles in three months (7/1 -10/1). 3500 miles driven in that time. 2.34 miles lost for 3500 miles driven is extreme. I'm very suspicious. I started logging with tesla fi to get documentation on it. The true range loss is much worse, as I dropped 5RM off the range over night one day and that's what spurned me to start documenting it. ~7 miles lost since January of this year.
You really need to look at voltage before you can say you are experiencing capping which is what this thread is about.
