Оптимизирайте операцията за периодично извличане на местоположението на потребителя android

Опитвам се да разработя приложение за Android, което ще използва картата на Google и ще извлича местоположението на потребителя на всеки 5 минути и ще го показва на картата.

Имам три въпроса:
- Как да планирам услуга за намерение, така че местоположението да бъде извлечено за 5 минути?
- Моят код подходящ ли е за постигане на тази цел?
- Как мога да оптимизирам използването на батерията с то?

Благодаря
Ето моят код :

public class RetrieveActivity extends AppCompatActivity
    implements
    OnMapReadyCallback,
    GoogleApiClient.ConnectionCallbacks,
    GoogleApiClient.OnConnectionFailedListener,
    GoogleMap.OnMyLocationButtonClickListener {

public static LatLng mCurrentLatLn = null;
MapFragment mMapFragment;
// The map used in MapFragment
private GoogleMap mGoogleMap;
private GoogleApiClient mGoogleApiClient;
private String KEY_CURRENT_LAT_LONG = "KEY_CURRENT_LAT_LONG";

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Log.d("safer", "onCreate ");

// startService(); setContentView(R.layout.activity_main);

    buildToolBar();
    // Create a GoogleApiClient instance
    buildGoogleApiClient();

    mMapFragment = (MapFragment) getFragmentManager()
            .findFragmentById(R.id.map);

    mMapFragment.getMapAsync(this);

}

@Override

    super.onResume();
    mGoogleApiClient.connect();
