I have had problems with Ring 2 Doorbell battery discharging very quickly ever since winter. It is about a year old and the battery used to last months. I thought maybe I had damaged my original battery duing the winter by charging it while cold, so I bought a new one and charged it to full "green light" status. I installed it yesterday and today it is at 19%. Low temperature over night was 54F. High temperature this battery experienced was 80F. RSSI -36. What is going on? Can the Ring Doorbell 2 be shorted out or what?
