I am having the same issue. First hooked it to solar after 100% charge. It worked a couple days and stayed fully charged. After a week or so I say the battery drain 1% a day. Then called support and they sent a new panel. First I charged the cam to 100% again and it took about 12 hours which it should not. The for about a week it was fully charged. Then it started discharging the same way. Is it a bad camera or just a bug. It is so annoying as I wan to add more but not if this is the experience.
