I have two SoH measurements, so listing here two data points :

This one from August :
1) unknown
2) 96.7%
3) 3900 miles (6275km)
4) 330 kWh
5) May 2022
6) Charged 39 times, 14 charging 95% or more. Charging only 2 times from below 15%

Second one from December :
1) unknown
2) 92.7%
3) 9333 miles (15021km)
4) 493 kWh
5) May 2022
6) Charged 93 times, 39 charging 95% or more. Charging 11 times from below 15%

Finland, so cold winters

Curiously (and not statistically robust at all at this stage) but 4 of the 5 lowest SoH readings to date are in Turbo or Turbo S models.

How does one check their battery SoH?
You need to purchase/avail of an OBDII scanner/tool and use with (usually) free OBDII readout software e.g. CarScanner. As pointed out in this thread there are cheap Chinese knock-offs out there (that do work fine and that I did in fact purchase w/o realizing TBH!), but also legit companies/developers that sell these for very reasonable cost i.e. ca. US$85. These tools can provide a ton of data beyond basic SoH data and are 100% safe to use with your car - great cheap piece of kit to give you real and useful data on your car.

Appreciate the context. I am interested in learning more about the car.

Interesting! I have not been following the Forum much lately, but wonder if you can see if the majority of these curious samples also are related to the first model, MY2020.

I think I saw a post (think by @rs38 ???) about different chemistry in the first model year compared to later cars?? That is perhaps linked here?

Spot on - the data is actually there in the spreadsheet I have posted and keep updated in my first post - all 5 are 2020 (one 2019) builds! (modified chart comment to reflect your post).

The TSB does not say much though -- it may be a slightly different cell without much impact in practice. That is my guess or otherwise Porsche may have made this more public ??

Also, I am not sure if we have enough data to draw any conclusion -- I think in my case the low score is due to a single cell; there is a screen in the Car Scanner that shows all cells as a bar graph and one of them was a bit lower than the rest. My car is in service now (for the Update) but when it gets back I'll post a screen shot.
