From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

There’s two things you might be talking about here:
The old way of making sure nickel cadmium batteries didn’t degrade, which was to discharge them all the way and charge them back up all the way. Your new laptop is almost certainly using lithium ion batteries which are chemically “damaged” more through that process than just leaving them plugged up all the time.
You could be talking about the old way of dealing with charge controllers, where the controller relied on the bios or os to tell it what to do and didn’t “know” how to respond to batteries at different stages of charge. This hasn’t been the situation for like fifteen years. Nowadays charge controllers go “yup, ready to go boss, 12345mah of charge, 90%” when some bios or os polls them.
You don’t even need to manually keep your battery in the 20-80 range nowadays since almost every charge controller automatically monitors temperature and adjusts charging parameters to not damage the battery. It’s not like the old days where the charge controller was just an ic controlling a fet acting as a slucegate between the battery and the power brick.
Heck, lithium ion batteries nowadays last longest the longer they’re plugged in. Running them to <10% every charge cycle actually diminishes battery life!
Tldr welcome to the future, don’t worry about it!
Thanks for the detailed reply! I learned a lot from it. Cheers!
