Has anyone seen this type of drop of in their battery health?
I have a Model 3 LR AWD with AP3
You've got no deg or drift. It showed over 310 miles not even 100 miles ago. Don't be fooled by the straight line. It's misleading. Further, as it gets colder out, your car will have more phantom/vampire drain. I've noticed that Stats is anywhere from 1% to 3% or more below what the car says. So, the rated range number starts to show lower. It can show 15 miles lower.Not nearly that steep, but I think I’m going to do a full 100% charge soon just to see where it comes in. Was hoping I’d have the miracle battery but this is well within the realm of normal. Less than 1%. Wondering how much of it is weather related - was holding at a steadier clip until it got cold.
Also, approximately the time my wife started driving it every day ... so maybe that’s it.
My goodness, at this rate, in 10 years I’ll only have about 290 miles of range! Whatever shall I do?

Whatever is your charging routine, give it a change. Change your SOC level by at least 10%. That often corrects BMS drift issues.Has anyone seen this type of drop of in their battery health?

That shows 3 apps, the Tesla app, Stats and EV Watch. You can see Tesla says I have 59% while Stats says 60%. It's always off by at least 1% and sometimes even 5%. That's due to phantom/vampire drain. The Stats SOC %age doesn't seem to update, while the Tesla app does. EV Watch must be pulling the same data as Stats. Obviously, as it gets colder, this difference gets larger. So, when Stats shows an oddly low range estimate, I look at the SOC for the Tesla app and Stats. When you divide Rated Range by the correct SOC %age, my rated range is always normal, but Stats will show a drop. It's all due to the colder temps and phantom/vampire drain.
I told the Stats developer last Winter, he dismissed it, but you can see, the Tesla app matches the car's display, and differs from Stats.

Agreed, the Stats developer says the SOC %age comes straight from the API. That's why all the 3rd party apps seem to show the same small error, as they all pull the same figure from the API.I also noticed the 1% difference between what the tesla apps shows and what teslamate (another tracking tool) shows. This may be due to API changes from the tesla's end?

I was trying to figure out how to get a proxy for the difference, and surmised it was the phantom/vampire drain, since when I pull up the Stats phantom drain data, my biggest errors occur when my phantom drain figures are the highest.
In Summer, my drain, as reported by Stats is 0.1miles/hr, better than average. Very low. My Rated Range figures as reported by Stats are all pretty spot on hovering between 306 and 312 miles.
However, when it's cold, Winter, and thru the shoulder months, my drain starts to get quite bad, 0.4miles/hr, worse than average. Some days, 0.8miles/hr. My Rated Range figure on those days can be quite poor, as low as 290 miles. You can literally match the worst drain days with your weirdest Rated Range dots in Stats.
