Bug ID: 472603
Summary: Wrong / outdated charging rate
Classification: Applications
Product: plasma-systemmonitor
Version: 5.27.6
Platform: Neon
OS: Linux
Status: REPORTED
Severity: minor
Priority: NOR
Component: general
Assignee: ksysguard-b...@kde.org
Reporter: helium...@mailbox.org
CC: ahiems...@heimr.nl, plasma-b...@kde.org
Target Milestone: ---
SUMMARY
When monitoring the "Lithium Ion Battery Charging Rate" sensor, the reported
charging rate is
a. negative when charging and when discharging, so it's not clear from the sign
whether the battery is charging or discharging
b. updating infrequently in varying intervals: often (not always!) the charging
rate seems stuck, and doesn't change, even when change is expected due to
different system load. When plugging the device, charging rate is always stuck
at the last discharge value.
STEPS TO REPRODUCE
1. Have a system with a battery, unplugged
2. Open System Monitor
3. Add a "Charging Rate" sensor
4. Start stress-ng
OBSERVED RESULT
charging rate does not change (usually, not in 100% of cases)
EXPECTED RESULT
charging rate should change from ca -4 W to ca -25 W
SOFTWARE/OS VERSIONS
Linux/KDE Plasma: KDE Neon 5.27
(available in About System)
KDE Plasma Version: 5.27.6
KDE Frameworks Version: 5.108.0
Qt Version: 5.15.10
Kernel: 5.19.0-46-generic (64-bit)
Graphics Platform: Wayland
ADDITIONAL INFORMATION
/sys/class/power_supply/BAT0/power_now seems to report correct data, at least
it produces a way more credible value and updates when system load is changing.
This is not a new issue; it has also occurred on older versions, at least for
half a year.
When checking "About System" and selecting "Show More Information", in the
energy tab I also see a wrong value in "Energy Consumption", so it's quite
possible that actually the issue is not (only?) in System Monitor.
Device: Huawei Mateboox X Pro 2018 / MACH-WX9, Intel i5-8250U
