	default boolean shouldEnableBatteryLevelNotifications(@NonNull final BluetoothDevice device) {
		return false;
	}
This method should return true if Battery Level notifications should be enabled on the
target device. If there is no Battery Service, or the Battery Level characteristic does
not have NOTIFY property, this method will not be called for this device.
<p>
This method may return true only if an activity is bound to the service (to display the
information to the user), always (e.g. if critical battery level is reported using
notifications) or never, if such information is not important or the manager wants to
control Battery Level notifications on its own.

@param device the target device.
@return True to enabled battery level notifications after connecting to the device,
false otherwise.
@deprecated Use
<pre>{@code
setNotificationCallback(batteryLevelCharacteristic)
      .with(new BatteryLevelDataCallback() {
          onBatteryLevelChanged(int batteryLevel) {
               ...
          }
      });
