Since GNOME 48, users can now on a limited set of hardware configure battery health preservation by setting charge limits. This works by setting a start and stop charge limit to prevent trickle charging or always charging the last X% of the battery preventing unneeded wear when they are mostly used plugged in to external power.

In this talk the existing sysfs API is explained, its limitations and the implementation of a new API (charge_types) to support specific Dell laptops and move other laptops over from non-standard sysfs API's to a new API which applications like UPower will use to offer battery health preservation to more models.
