Public bug reported:
The Battery Optimization 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,
3666923520 2021-11-19 Fri 15:13:58 kubuntu/jammy-desktop-amd64.iso and
3667288064 2021-11-13 Sat 14:10:03 kubuntu/jammy-desktop-amd64.iso.
On a recent morning i had found a third section in [Advanced Power
Settings] called Battery Optimization or something quite like that, 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 Battery
Optimization 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?
