does keep the power cord plugged into a MAC diminish the life or storage of the battery?

My battery does not seem to achieve 100% charge despite the power cord being plugged into the device. Overnight the charge level was 79% despite being plugged in overnight


MacBook Air, macOS 13.4

Leaving the computer plugged in will not damage the computer or the battery. The MacOS manages the power/charging system very well. Maybe you have optimize battery charging on.
