One of my cameras won't hold a charge

One of my cameras won't hold a charge for more then 4 weeks I have 2 essential spotlight and it's only 1 that keeps going flat we turn them off most of the time as some one is always home

Have you tried swapping the cameras?  Then see if the problem moves with the camera or stays with the location.

Power drain can be caused by a lot of motion near the problem camera, or a marginal wifi signal.
