Is charging MacBook Air's battery to 100% and keeping it above 20%, a safe practice?

Question

I ensure my MacBook M2's battery never drops below 20% and always charge it to 100%. Is this practice safe, or could it potentially harm the device?

It is a good idea to use optimized charging. The battery then charges up to 80%. If you expect to need more, you can do this sporadically.

If you don't need your mac on the go, it's a good idea to keep connecting to an outlet
