I installed a solar charge on a Ring doorbell 3 on 8/27/20. The doorbell faces south, a perfect spot for solar. I charged the battery to 90%. Device health shows solar connected, power level stayed around 90%. Then it said 18%, and was put offline. I had to remove and recharge the battery today. I have a doorbell 2 facing north, no solar charger. I charged battery up to 100% on 8/27/20. The power level was 50%. So solar charger so far works worse than no solar charger. I fully charged both batteries 100% today. I also installed a solar charger on the one facing north today. It says solar not connected. I will give it a week to show solar connected. Now I will see solar charger work on doorbell facing N. or S., or worse, stay tuned.
