Critical battery threshold is disregarded

I’m using Kubuntu 25.04 with Plasma 6.3.4, and I’m having some trouble with the battery thresholds.

I set “Low level” to 15% and “Critical level” to 10%, but I get zero notifications or screen dimming or anything until my laptop hits 3% (at which point it says my battery is at critical level), and even then my laptop still doesn’t sleep like the screenshot says it should.

What I’d like to happen is get a notification and screen dimming at low level (so 15%) and then more aggressive screen dimming and another notification at critical level (so 10%), but I’m flexible, as long as I can actually raise it from the default 3% for critical to something more reasonable.

Is there a way to do this that I’m missing, or is this a bug that I need to report?

This is probably a bug you should report.
