Thanks for the update, @NickA! As mentioned in our Community post about battery drain, connection variables can be related to a battery draining. If the device is working harder to connect due to distance or interferences, it can drain battery quicker compared to a Camera that is not. It is also a common factor in live view connection concerns. Check out your RSSI in the device health section of the Ring app, to ensure for optimal wifi signal.
I see a reset has also already been suggested in this thread, which would be the best next step, as well as fully charging the battery if you were on site. Feel free to check back here to see if any neighbors chimed in with suggestions.
