[ltp] T480s, battery state jumping from fully-charged to charging while plugged in, battery LED doesn't change

[Rubin Abdi]

Hello.

I'm running Debian Sid 5.16.0-4-amd64 from the repo. I just did a long
needed aptitude safe-upgrade (I don't believe my kernel got upgraded).
After reboot I am seeing upower -i
/org/freedesktop/UPower/devices/battery_BAT0 report the state of the
battery going from fully-charged to charging every few seconds (which is
throwing up notifications in KDE every few seconds). The charging indicator
LED on the machine is maintaining white for fully charged (yes I know this
is subjective). Battery percent is maintained at 99%.

Additionally about a month ago I replaced the battery in this machine to a
new generic one off of Amazon, after install and discharge/recharging the
thing a couple of times upower reported about a 94% battery capacity (which
I feel like is typical of generic replacement batteries). Today it's at
93.1404%.

I looked through the "Battery recalibration" thread from April, I could
have sworn linux these days (along with the bios) manage recalibration on
their own, but I suppose I'm mistaken.

So at this point I don't know if the issue is something got tweaked on this
last apt upgrade, or a recalibration needs to happen. Any advice would be
appreciated.

Thanks.
