"Best practices" (?) with laptop battery driving me crazy (lemmy.ml)

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?

I don't have a Lenovo, but a Dell Latitude that i use like a desktop, mostly plugged in next to my couch. In the bios you can set it to optimize the battery and charging for 'primarily AC usage', as well as set a percentage to limit charging, I think I have it set to 85%, I would assume you can do the same on a Lenovo.

I wouldn't worry too much about it past that, if leaving it plugged in all the time is convenient, just do that. You could also probably buy a new battery on eBay and replace it if your battery is actually shot and you want better life.

Unfortunately, and somewhat surprisingly, there does not seem to be anywhere in the BIOS to set thresholds on my Lenovo.
