I just put up the spotlight cam and Solar panel. It was charging back to 100% every day but today. It’s at 40% and hasn’t moved all day. It’s a bright day and has been getting full sun ever since the sun came up. I stopped all motion and recording today to make sure it wouldn’t continue draining while trying to charge. Still not moving in % but says it’s connected.
I found for one of my Ring cameras that the % displayed in the app only updated once a day. So you might see if waiting 24 hours will give you an updated % figure.
