It probably is trying to charge it, but batteries are chemical mixes, so

 - there is no real 100% or 0% - the software is handwaving to some extent...

 - the charge and performance of the battery changes with many
variables, and generally degrades with use

so I have many batteries that after some use I only see reported as
"95% charged". Even if they get more "charge", the battery doesn't
hold it. Or perhaps the software estimated the capacity a bit too

In short, the % you see is a fiction, a bad simplification. This is
increasingly apparent as you use older batteries, and in general as
you gain experience with different batteries...
