On my 2015 MacBook Pro 15 inch with 2.5 ghz I7 the battery capacity reads 7200 mAh. I have 220 battery cycles and I know stock it has about 8200 mAh. Is there a reason for this and can I improve it?
 
A laptop battery will degrade over time even if it's never used or charged. There is nothing you can do to prevent it from degrading.
