Battery charge limit
In order to extend the lifetime of the laptop battery, charge limits can be set. There is a Dell utility to do this called Dell Command Configure, but it only supports old versions of Ubuntu, and does not work with Arch due to dependencies on old system libraries.
But there is a better solution. Install. Then, to limit the charge level to 80%:

To revert to the default settings:
# smbios-battery-ctl --set-charging-mode=adaptive
