Ring Solar Stick-Up

I have had my Stick-up Battery installed using the solar panel since day 1. I have been using the camera for a few months now and love it. For the first 2-3 months the battery health has been above 90% and the majority of time close to 100. Recently the battery has been draining very quickly. Just yesterday it was at 12%. I have not changed or modified any of the settings that would cause the camera to drain faster. On the contrary I think it should be getting more sunlight now, as my neighbor cut down a large 100yr old tree that was blocking some morning sunlight. The solar panel is clean from debris. The only factor that has changed is when I installed it, it was July and 90 degrees and today is October 5th and its 60 degrees. I can understand some drainage from colder weather but almost draining down to the last 10% with a 30 degree drop seems very unlikely. Could the battery be bad? Could the solar panel be bad?
