Set this policy to 'ActiveWhenUnplugged' and efficiency mode will become active when the device is unplugged.

Set this policy to 'ActiveWhenUnpluggedBatteryLow' and efficiency mode will become active when the device is unplugged and the battery is low.

Set this policy to 'BalancedSavings' and when the device is unplugged, efficiency mode will take moderate steps to save battery. When the device is unplugged and the battery is low, efficiency mode will take additional steps to save battery.
