172000km after 3 years Model Y

172,000 km in 3 years with a Long Range Legacy Model Y — and I haven’t strictly followed the 20–80% charging rule.

Out of curiosity, I used an app I found on the app store to estimate my battery health, and the result came out between 88%–91%.

Does that sound normal for this mileage and age, or does it seem off?

I can try to help if anyone is curious about how I measured it.
