[Bug 2116870] [NEW] Battery charge regularly stuck at 90%

 

Public bug reported:

Hello,

I am experiencing an issue with battery charging on my Dell Precision
5690 running Ubuntu 24.04, kernel 6.8.0-63. The battery frequently gets
stuck at 90% charge, even while plugged in. To try and reach a full 100%
charge, I need to unplug the power, completely shut down the system, and
then restart.

However, this workaround does not always restore charging to 100% —
sometimes, even after a full shutdown and reboot, the battery remains
capped at 90%.

This behavior seems to occur intermittently and is not related to any
charge threshold settings that I have knowingly configured.

I have attached a charge history graph generated with gnome-power-
statistics. It shows periods of normal 100% charging, followed by
repeated instances where the charge caps at 90%, and more recently one
instance where it reached 100% again.

Is this expected behavior, or could it be a bug in the power management
system?

Thank you.
