Bug ID: 491731
Summary: battery applet should not report that the power supply
is not powerful enough to charge battery when it is
above the stop charge limit
Classification: Plasma
Product: plasmashell
Version: 6.1.4
Platform: Fedora RPMs
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: Battery Monitor
Assignee: plasma-b...@kde.org
Reporter: janne-...@jannau.net

Target Milestone: 1.0
SUMMARY
Notebooks with configurable battery charge thresholds might discharge the
battery if it is charged above the charge end threshold. This behaviour is
useful for battery health on systems which are connected to a charger most of
the time. Waiting for the battery self discharge after a full charge will take
a long time at which the battery is charged to an unhealthy level.
The linux kernel's sysfs has no property to report this and the documentation
for charge_control_end_threshold just specifies that charging will stop at this
threshold.
The battery applet should not confusingly suggest that power supply is is not
powerful enough in this situation.
STEPS TO REPRODUCE
1. Charge the battery in an Apple silicon / asahi notebook to ~90% and connect
a charger
2. Configure the charge limit stop threshold to 80%
3. look at the battery applet tool tip
OBSERVED RESULT
battery applet tool tip reports:
"Battery at 90%, plugged in but still discharging"
"The power supply is not powerful enough to charge the battery"
EXPECTED RESULT
"Battery at 90%, plugged in, discharging"
"Battery is configured to charge up to approximately 80%"
or simllar
