Battery life down

When I first got my 2k doorbell, it lasted 186 days before needing charged. I charged it up and it’s needing charged again after only 42 days.

I’ve not changed any settings that would run the battery down.

I’m also finding that even though I have it on human only detection, every now and again it’s picking the fog up in the garden.

Anyone finding similar problems or gave any solutions please?
