Stop charging at 100

I’ve noticed a new issue recently and I'm not sure if it's due to a recent update or a configuration change.
My laptop is usually plugged in all the time because it has very poor battery backup. Earlier, this setup worked fine, but now I’m seeing a problem:

There seems to be a setting where charging automatically stops once the battery reaches 100%. However, because my battery drains quickly, as soon as it drops to 99% (which happens within 10–15 seconds), the laptop immediately starts charging again.

This constant cycle causes a plugged-in/plugged-out notification sound to play repeatedly, which is very distracting and annoying.

This behavior wasn't happening before. It’s only started recently.

Any help would be appreciated!

I would imagine that charging is being controlled at a very low level and its trying to compensate for a dying battery.

A workaround / solution may be to just disable the notification.

Some notebooks (notably lenovo) will allow you to set charing thresholds, https://wiki.archlinux.org/title/Laptop … ry_control
So the hardware model will matter a lot here, but in general I'd agree w/ Nikolai5 - the battery seems to be on its death bad anyway, you're using the system as desktop w/ the rattling battery as poor man's UPS and the only problem about that is some pointless notification. Disable the notification.
