MacBook Pro (model:A2251) battery concern

My laptop is fully charged (100%) when I turned it off (in sleep mode). where status is Low battery mode is ON and no apps using significant energy. I have noticed when I turned on my laptop after 3 days it has been fully charged, the battery drops to 92%. May I ask the reason? see below screenshot of my battery settings. thank you

Other than letting Mac sit there while plugged-in and automatically regulate

its status. That being charge awhile and then coast; if not sleeping. It won't go

over the 'full' charge. But may try to maintain any losses, if left plugged in.

Just be sure it's really turned-off if you want to see how it

holds a charge over a week's time; and leave it plugged in.


Good luck & happy computing! ☺︎
