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?
How long do you need the battery to last? My personal experience limiting a Dell convertible tablet to an 80% charge and keeping it plugged almost all the time was the tablet failed before the battery did. After 7 years the Dell battery utility still showed very little degradation and the battery hadn’t swelled at all.
I have multiple laptops (a couple used as servers) and mostly keep them at a 75% charge.
