What is the best practice to optimize Li-ion battery life with an M series Macbook?

I have a newer Macbook Pro. I have heard conflicting methods for optimizing battery life as far as charging and discharging. Some say leave it plugged in all the time. Others say don't leave it plugged in all the time.

What does Apple recommend and what do you recommend and practice? Thanks for your suggestions!

MacBook Pro 14″, macOS 14.6

Here are Apple's recomendations:


Batteries - Maximizing Performance - Apple


Leaving the Mac plugged in all the time is fine. Your Mac will charge when it needs to. What you don't want to do is fully discharge it on any sort of regular basis. That will speed the degradation of the battery.


Ultimately the best general suggestion is to just use it as you need to and don't worry about it.


Regards.

My Samsung Galaxy phone has a Battery Charging option which stops recharging the battery when it reaches 85% capacity. It is supposed to extend the battery life by not recharging to a full 100% level. There doesn't appear to be any 'charging option' settings on Apple Macbooks. I have had good luck with Macbook battery life over the years. But I would like to keep this one working as long as possible. I appreciate your practical advice! Thanks!
