Battery Keeps Dying

I keep having this issue where my battery will die if my car sits for more than a day. I took it to the dealer, and they said it was due to the "aftermarket" dashcam, which I then removed. The issue still remained. I had it jumped last time, and the person saw that the battery health was at 0%, but when it was at the dealer previously, it was stated to be at 92%. Do you think I should replace the battery?
