Ok, well, to start with, my Lenovo X1 Carbon 10th is known for not having the greatest battery life.

Despite this, to preserve battery health, I have notifications set to warn me when a charge goes under 20% or over 90%, so that I either plug in or unplug when I get them, which TTBOMK constitutes "best practices." Very possibly I'm just getting old and getting lost too deeply in whatever I'm doing, but I feel like I'm constantly getting these notifications, and they're really starting to get on my nerves!

I've tried tlp and auto-cpufreq without any noticeable difference in performance, and usually I'm on "Power Saver" in Mint.

Mrs. Erinaceus has a gaming laptop and just keeps it plugged in all the time, battery health be damned. Is that what I should do? Maybe time to get a new battery? Or is there just some way to tell it to stop charging and leave it plugged in?
