This is a strange move. I hope it returns but honestly I haven't used it myself and prolly won't.
I remember back in 2018 or so hearing how many battery variants were in Tesla cars, just under 20 IIRC! I can't imagine how many there are NOW.

I can't say I'll miss this feature, since I never really used it or ever planned on using it. The only reason I could see a use for it, is if you plan on selling your car yourself to a third party, or something along those lines. Outside of that, I think it would just cause more unwarranted concern when customers see their battery degrading over time.

2023 MYP HW4 - 2025.26.4. I still have the test option. Last used Feb 8 this year.

Out of pure curiosity, what were your results? How many miles do you have on the car?

I had about 20,000-23,000 miles at the time, and degradation was at 12%. I now have 33,000 miles on it and degredation as reported by S3XY Commander is at 16.5%. I have not run the battery test again, but I notice two things with it. First, it says battery is healthy. Second, it no longer gives the old 12% test value from February; it doesn't give a value at all.
