Solar not charging propertly. Was charging but actually did not charge

I have the S220 Solocam. It is in partial shade but usually at half charge. I put it in the sun to fully charge. I wanted to see how long a charge last for and if I can keep them where their at. I have two. I placed them in full sunlight. they were both charging. Now they are not. One was 26% when I put it in the sun. A few house later it was charging, now it’s not and the charge did not go up. Still at 26% in the sun. Any ideas?

P.S. Why is there no drop down box for CHARGING? I’m sure it’s a top concern!

Hi, what was the temperature in your area? If it’s too hot, say like above 90° f the internal temperature of the camera would be much hotter and then a battery safety feature would cause it not to charge the battery.
Operating Temperature
-4°F - 122°F (-20°C - 50°C)

Sounds logical. But then again, the sun charges them and the sun is hot.:crazy_face: It wasn’t quite that hot today but the sunlight could have been that hot. I’ll have to wait until tomorrow to find out. Thanks for the information.
