Broadcast Action: This is a sticky broadcast containing the charging state, level, and other information about the battery. See Android.OS.BatteryManager for documentation on the contents of the Intent.
You can not receive this through components declared in manifests, only by explicitly registering for it with Context.RegisterReceiver(BroadcastReceiver, Android.Content.IntentFilter). See Intent.ActionBatteryLow, Intent.ActionBatteryOkay, Intent.ActionPowerConnected, and Intent.ActionPowerDisconnected for distinct battery-related broadcasts that are sent and can be received through manifest receivers.
This is a protected intent that can only be sent by the system.
