Previous max SOC + KW was about 135 low down and 125 at 50%.
Afterwards it's about 110 all the way through. Although I made a recent discovery. If you're on a long trip and you hit a very busy super charger where they want you out as fast as possible, Tesla is upping the max. I've seen it multiple times where I'm getting 125 at 30% and 120 at 50%. That's about half of the difference lost.
The way I've made up for it is that I now leave the house at 100% every time I'm going on a long trip so that the first charge is less time than if I only needed 70% to get to the first supercharger. i.e I'm intentionally beating up on the battery to keep my first stop charge lower duration. Tesla forced me to do it with their cap.
The other thing I'm doing is that whenever we have a long stop where we're eating, rather than run out of the restaurant when I have enough plus a 15% buffer to get the next charger, I just leave it set to 100% on the the trip and reset it from 80 to 100% when Tesla lowers it at busy chargers. It's harder on the battery but it mitigates the next stop time duration.
Additionally, rather than shooting for a 15% buffer, I now shoot for a 5% buffer. It's slightly more risky but now I've done it dozen times and it seems to be fine. In all, we haven't really increased our trip time but we've had to change to behaviors that will dramatically increase degradation. Since I'll be selling the car 6 months before the 8 year warranty expires, I'm fine with it. Too bad Tesla had to force me into it.
