Battery Charge Limit
Feature summary
The gnome-settings should have an option to enable laptop battery charge limit which is needed for the longevity and safety of the battery.
This feature already exists in Android, iOS phones; and Windows OS I think as well.
How would you like it to work
Under the power settings in the gnome-setting, there should be a toggle to enable it and a slider or an input field to specify the maximum charging capacity needed.
