- The /proc/acpi/ directory structure of Linux 2.4.20 and 2.6.
- The /proc/apm file format of Linux version 1.3.58 or newer.
- The Haiku ACPI battery driver.
- BSD by using the apm program.
- Darwin (macOS) by using the pmset program.
- Windows via the GetSystemPowerStatus API call.
- Android via the BatteryManager APIs.
