Go step by step and test.


1. Reset PRAM:  Reset NVRAM or PRAM on your Mac - Apple Support

     Settings that can be stored in NVRAM include sound volume, display resolution, startup-disk selection, time zone, 

     and recent kernel panic information. 

     The settings stored in NVRAM  depend on your Mac and the devices that you're using with your Mac.


2. Reset  SMC:   How to reset the SMC of your Mac - Apple Support   Choose the appropriate method.

    Resetting the system management controller (SMC) can resolve certain issues related to power, battery, fans,

    and other features.


3. Startup in Safe mode. https://support.apple.com/en-gb/HT201262

    To leave Safe Mode, choose “Restart” at the bottom.

    Quote:

     Safe mode prevents your Mac from loading certain software when it starts up, including login items, 

     system extensions not required by macOS,

     and fonts not installed by macOS. It  also does a basic check of your startup disk, 

     similar to using First Aid in Disk Utility

     And it deletes some system caches, including font caches and the kernel cache, 

     which will be created again automatically as needed.

Batteries are considered Consumable Products. Over time it will degrade to a point where it needs to be replaced. In you case - the usage is normal as the capacity will go up and down all the time and never stay always at 100%. Apple Batteries are rated for 1000 Full Battery Cycles and / or 80% Capacity before needing Evaluation or replacement.
