Efficiency mode enabled

Enables efficiency mode which helps extend battery life by saving computer resources. By default, efficiency mode is enabled for devices with a battery and is disabled otherwise.

If you enable this policy, efficiency mode becomes active according to the setting chosen by the user. You can configure the efficiency mode setting using the 'EfficiencyMode' (Configure when energy saver (previously named efficiency mode) should become active) policy. If the device doesn't have a battery, efficiency mode is always active.

If you disable this policy, efficiency mode is never active. The 'EfficiencyMode' and 'EfficiencyModeOnPowerEnabled' (Enable efficiency mode when the device is connected to a power source) policies will have no effect.

If you don't configure this policy, efficiency mode will be enabled for devices with a battery and disabled otherwise. Users can choose the efficiency mode option they want in edge://settings/system.
