Gio.PowerProfileMonitor

interface

GPowerProfileMonitor makes it possible for applications as well as OS components to monitor system power profiles and act upon them. It currently only exports whether the system is in “Power Saver” mode (known as “Low Power” mode on some systems).

When in “Low Power” mode, it is recommended that applications:

  • disable automatic downloads;
  • reduce the rate of refresh from online sources such as calendar or email synchronisation;
  • reduce the use of expensive visual effects.

It is also likely that OS components providing services to applications will lower their own background activity, for the sake of the system.

There are a variety of tools that exist for power consumption analysis, but those usually depend on the OS and hardware used. On Linux, one could use upower to monitor the battery discharge rate, powertop to check on the background activity or activity at all), sysprof to inspect CPU usage, and intel_gpu_time to profile GPU usage.

Don’t forget to disconnect the GObject.Object.notify signal for PowerProfileMonitor.power-saver-enabled, and unref the GPowerProfileMonitor itself when exiting.

Methods

get_power_saver_enabled

def get_power_saver_enabled(self) -> bool

Gets whether the system is in “Power Saver” mode.

You are expected to listen to the PowerProfileMonitor::notify::power-saver-enabled signal to know when the profile has changed.

Static functions

dup_default

@staticmethod
def dup_default() -> PowerProfileMonitor

Gets a reference to the default PowerProfileMonitor for the system.

Properties

power_saver_enabled

power_saver_enabled: bool  # read-only

Whether “Power Saver” mode is enabled on the system.
