I have a service that performs background updates. I want to give the user the the option to disable the updates when their battery percentage reaches a certain level. From my research, I'm going to use a receiver in the onCreate method of my Service class, eg:

 public class MainService extends Service  
 {  
     @Override
     public void onCreate()
     {      
        this.registerReceiver(this.BatInfoReceiver, new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
     }

    private BroadcastReceiver BatInfoReceiver = new BroadcastReceiver(){  
         @Override  
         public void onReceive(Context arg0, Intent intent) {  
           int level = intent.getIntExtra("level", 0);  
    }  
  };
 }

I'm assuming the best practice is to leave the service running and check the battery level in the service and not perform the CPU intensive code based on the percentage? I don't actually stop the service itself and start it up again, based on the battery percentage?
