Interface
GioPowerProfileMonitor
since: 2.70
Description [src]
interface Gio.PowerProfileMonitor : Gio.InitableGPowerProfileMonitor 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::notify signal for
GPowerProfileMonitor:power-saver-enabled, and unref the
GPowerProfileMonitor itself when exiting.
