Bug ID: 444847
Summary: Battery health jumps all over the place.
Product: plasmashell
Version: 5.23.2
Platform: Other
OS: Other
Status: REPORTED
Severity: normal
Priority: NOR
Component: Battery Monitor
Assignee: k...@privat.broulik.de
Reporter: yiz...@kulodgei.com
CC: plasma-b...@kde.org
Target Milestone: 1.0
In the one month I have been using KDE Plasma 5 and occasionally I hover over
my battery system tray icon. The battery health % keeps jumping all over the
place. I have seen the following in roughly this order:
100%
98%
99%
96%
100%
98%
100%
97%
99%
100%
Can the algorithm for this be looked at and improved if possible?
STEPS TO REPRODUCE
1. Buy a new laptop and install KDE Plasma minimal
2. Hover over the battery system tray icon and note the battery health %
3. Use your computer as you would for a couple days
4. Hover over the battery system tray icon and note the battery health %
OBSERVED RESULT
Not guaranteed but the health will probably say a number between 95% and 100%.
EXPECTED RESULT
Battery health should be accurate. It should not be possible for the battery to
lose up to 5% of battery health in the matter of a few days when it is only
used a couple hours a day. At which point the laptop battery would be dead
within the span of a month or two. Let alone for the battery health to improve
itself.
