Something related to the battery, which are charge thresholds, are supporte= d in multiple laptop brands (Lenovo ThinkPad, ASUS, System76...) and are thus are exposed in the battery power supply device (/sys/class/power_supply/BAT0/charge_control_{start,end}_threshold) conservation_mode is basically an equivalent with a fixed value (60%) that = is exclusive to IdeaPads, and it's exposed in the platform device (/sys/bus/platform/drivers/ideapad_acpi/VPC2004:00/conservation_mode). I guess that my the verdict is that, because rapid charging is supported on multiple laptop series (both ThinkPads and IdeaPads, which use different drivers, and maybe there are more brands, though I couldn't find anything on Google), so it should be exposed in the battery power supply device. --=20 You may reply to this email to add a comment.
