Ring Doorbell 3 Plus hardwired and battery life draining

I have hardwired Ring Doorbell 3 Plus. Device health showing that Ring is hardwired and I have strong WiFi signal. This device is new and I have received it yesterday. This Ring is inside the building (apartment complex), location - California. That mean that I have pretty stable warm weather. My question is: What the heck and why my NEW battery on NEW device is draining? When I was selecting your product it was said that it can be hardwired and battery should not be drained. Or this is just a market trick? If so what the point to have this doorbell wired if I still need to charge battery?! Yesterday evening, I have fully charge the battery - 100% and now I have 97% after a day. Are you guys kidding me? Do not tell me that I need to disable some Motion settings, what the point to have them if I need to disable them? Can you fix this problem ASAP?
