Huh my Pixel 3 XL also just died in a very similar way the battery was starting to lose charge faster than expected and a few nights ago it died again and then wouldn't power on. It was taking charge, I plugged it into a powerbank with a wattage meter, and it was pulling just 5W over USBC. (The powerbank supports full PD) It's probably the wrong spot to report this sadly so it's probably been muted it seems like a hardware issue not an issue with Android itself.
