Hi all,
I think I found my problem. I had linked my doorbell and my two floodlight cams together so they would all record when any one of them picked up motion. I live on a somewhat busy corner so there were already quite a few events triggering my cameras individually but linking them all must have just been too much for my doorbell. I unlinked the doorbell from the floodlights, charged up the battery manually, and since then the battery has remained 90-100% charged. It’s been several days now so it seems that was my issue. The doorbell wiring just couldn’t keep up with all of the new events the camera was handling.
I still wouldn’t mind knowing why it shows a solar charger is connected when I don’t have one. It’s still possible that is affecting the charge rate I suppose.
