I'm using MacBook Pro and it will be in charge nearly 12 hours in a day. I set the battery indicator to Percentage, so it is displaying the battery charge in percentage.
The problem I faced is, most of the time it showing 100%, but in some times, it stops (I don't know exactly) charging in 97% or in 99%. For a long time, it remains same until I discharge the battery then put again in charge.
What is the problem here?

It's all about charging your battery efficiently, resulting in minimal wear and tear where possible.
So, to try to illustrate it by example:
