2025 Porsche Macan — fast charging tapers earlier than it used to — trying to narrow this down

I'd want a measurement, not a hunch. Two 2025 Porsche Macans can feel identical and have different causes, so measure before you copy someone else's repair. That's the branch I'd chase this week. Was this after sitting overnight? I'd sleep better after that step, even if it finds nothing. Wrote this up on my lunch break.
