Ring 2 not charging on hardwire anymore (after doing so for 2+ years)

As the title states, I've had a Ring 2 on hardwire for more than 2 years. Within the last 6 months or so, I got a notification that the battery level was depleated. I checked the app and it still said the power source is hardwired. No matter, I removed the battery and charged it up and put it back in -- because that's what the Ring "Help" content told me to do.I consistently lost 1-2% of battery life a day, despite turning off all motion activity and snapshot. You read that right: the battery still drained despite triggering no events.I've had to charge the battery twice since then, and I put a new one in last week... it's at 80% and falling. The app still shows that it's hardwired, and I haven't made any changes to the connection since it was working. Oh, and it's not cold here either. I'm attaching a picture of my app settings.
