Why is my laptop battery charge topping at 79%?

This pertains to a 2 1/2 year old HP laptop.

I run it plugged in most of the time, but once a week I'll start the day unplugging it, and leaving it unplugged until it gets down below 10%, which usually takes about 5-6 hours.

Late last week, I got a Windows notification I'd never seen before, which I now can't quote verbatim, but it suggested using "battery optimizer" - I think that's what it was called - to "optimize" my battery. Hey, why not?

Except that

1. The next time I ran the computer unplugged, the battery drained to my needing to plug it in, in about four hours. Much faster than usual.
2. Then today I noticed that my battery was only 79% charged, though plugged in.

Below is a shot of my battery graphic:





Having been plugged in more than a day ago, it should be at, and holding at, 100%.

So how do I get the battery back to 100% charged? Is doing so advisable or not? What's a true "optimum" setting for the battery?

In asking the "optimum" question, I've never had a performance problem/issue with the computer; my main goal is that, when it is running on battery, it runs for as long as possible.
