2022 Tesla Model 3 Long Range — how are you estimating real battery degradation?

Dash range changes with temperature and driving, so I'm looking for a better way to judge battery health. What data do you trust—usable kWh, charging energy, service-mode values, repeated range tests? I'm in Phoenix. If I fix it I'll come back and update the thread.

Charge curves lie if you don't match starting SOC and temp. Match starting SOC and battery temp if you're comparing 2022 Tesla Model 3 charge sessions. That's where I'd start. Time, temperature, and whether it's in gear are the notes that actually help a shop. A day of patience here is cheaper than a wrong part. Heat soak after errands is the other window.

It did how are you estimating real battery degradation twice this week, both times after sitting. No change in mileage feel. I refuse to clear codes until someone else sees them.
