Why has the battery dropped so much and not gaining power back? I’ve had it for 18 days
Has it gone back to charging?
It’s up to 40% but won’t go past that
Hmmm.. is the blue circle in front of the camera lit, indicating that it’s being charged?
Check the solar panels USB-C power cord connection to the camera, remove it and then plug it back in.
If you’re using the extension power cord check those connections also.
If it’s still not charging, go out there with a power brick and a charging cable, or whatever you got so you can manually charge it to see if it will charge the battery that way.
