Bug Description
The Charge Limit section has gone missing ever since i changed the settings.
This morning i see only two sections, "Battery Levels" and "Other Settings", under [System Settings -> Power Management -> Advanced Power Settings], having just tried two recent jammy kubuntu live ISOs,

On a recent morning i had found a third section in [Advanced Power Settings] called "Charge Limit", and if memory serves me correctly i set it to begin charging at 40% and stop charging at 60%. But ever since, i only see the two sections in [Advanced Power Settings].
it makes sense that the panel icon is saying "Battery at 57%, not Charging" because that fits what i asked for, and not discharging either because as htop says it's "Running on A/C". i just unplugged the lappy momentarily and htop tracked it as it steadily dropped from "57.1%" to "56.6% (Running on battery)", so apart from the missing Charge Limit settings it all seems sensible. i was a bit surprised to see it remembering the settings from a prior live session, but it makes sense if the settings were set in the firmware.
in addition to what's currently (nearly) implemented in jammy kubuntu i'm curious about optimizing battery lifetimes in general, and specifically for my specific devices (see sig). Pointers to reasonably reliable specific information would be appreciated. Like, what's best overall, a full charge occasionally, a full discharge occasionally, both, neither, or more specifically what?

description: | updated |
Ran the battery down all the way this morning, restored power, booted into focal (on my HD), ran there most of the day, the battery charged up to 100%, then booted the jammy live iso again. The Charge Limit section is back now, showing the default settings, stop at 100%, always charge when plugged or something to that effect. Fascinating. So i clicked around within System Settings a bunch. Charge Limit still there. Changed focus settings, changed monitor settings, Charge Limit section still there. Changed Charge Limit settings like i did before, stop at 60%, start at 40%, clicked Energy Saving, answered "Apply" to the dialog, clicked right back to Advanced Power Settings, and the Charge Limit section is gone again now.
