I appreciate your help, but I am not 12.
That is good to know because the Terms of Use for these forums requires one to be 13 years or older. Note this excerpt:

Then you know that battery run time is a function of the number and type of applications in use, criteria you have not mentioned.
Have you reset the SMC and the NVRAM? If not consider doing so:

These resets may or may not have a positive affect on battery performance.

This may offer a clue to the sub-par performance you are experiencing and then it may not.
(It would be very helpful if you made certain that the charger were connected when you do so.)
Ciao.
