First two months, now two days doesn't sound like bad battery but like activated services.
Two months is realistic without sensor, if you use heart rate regular or gps or ... (possibly without knowing), battery gets drawn quickly.
Try disabling stuff in health app, ... and check again.
Interesting. Next time I charge it, I will try uninstalling all apps and watchfaces except the one I had running when I got good battery life. I'll also turn off all services I can in the settings, except bluetooth. I'll report back after that.
