notebook is a 10 year old macbook pro I installed xubuntu 24.04 in. It comes with an embedded battery.

First notebook I bought, not from apple, had a removable battery. The vendor told me to maximize its life I shouldn’t plug the battery in, unless I need it (like for traveling). This way, I’ve managed to keep the original battery in good working condition for 8 years so far.

Back to the macbook: I cannot remove the battery and constantly loading it to up to 80% and discharge it up to 20% seems ridiculous. Furthermore, this would deplete the battery even faster, I believe.

What can I do to spare the battery as much as possible?

    That highly depends on your model.

    1. Yes normally once the battery is fully charged, it should run from the charger. Probably runs from the charger directly but also charges the battery.
    2. The OS can limit the battery charging start and stop point. COSMIC desktop has such a feature. It may need interaction with the EC though.
    3. Yes, if the laptop is just running off the AC, charge it to 50% and keep it there. If not, then cycling between 20/80 is best. But that is unlikely, my 2012 thinkpad also runs direclty off the charging brick.
