> switching off the charger as soon as the battery gets charged 100%.

Batteries have a limited amount of charge/discharge cycles - if you are doing this you're unnecessarily wasting those. Keeping the device plugged in once charged is absolutely fine - the battery itself will stop charging and the power will be used only to power the device itself so it doesn't have to touch the battery anymore.

This stupid advice has been going around for ages and if it ever applied it definitely doesn't apply now - all modern lithium batteries use charging circuitry that stop charging beyond a certain point regardless of whether it's plugged in or not - if they didn't you'd be seeing battery fires everywhere.

yeah, if you really want to max your battery life you can even limit it to 50% or something: https://apphousekitchen.com/

Macs do this automatically but it doesn't seem to happen to me that often. Usually if I leave it plugged in for an entire weekend I think.

Wow, I did not know this is possible with a Mac now. I think Thinkpads supported this but not the Mac. Great find!
