notebook is a 10 year old macbook pro without macos 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?
My son has a gaming laptop that is plugged in constantly. I vaguely remember reading that all modern laptops protect the battery to some degree, though not sure how. I’m guessing it is by using the mains while charging. Not sure what the damage is to a battery that is constantly fully charged.
After reading this thread I hope this is true I have had 2 laptops plugged in one for like 5 years non stop (this one I deactivated the battery in BIOS it’s old) and the other for about a year…
The only thing that could potentially degrade the battery is not cycling it. There should be no direct effect on the battery due to using mains power
