Q: MacBook Pro - battery drains when shut down

I use 2014 MacBook Pro by connecting to the electric outlet.  When I go to sleep, I close all the programs, and shut the Mac down.  Many times when I turn  it on again with the electric outlet, I have full 100% charge.  Some days, I turn the Mac on and see the charge at 96% or so.  I make sure that every program is closed, and the power goes off before I close the lid.

Why does it drain the battery sometime?

 

When the Mac is turned on, and the charge is about 96%, should I just use it without connecting to the electric outlet as every charge is counted?

 

Thank you!
