Background-mode plugin causes high CPU usage

[n1705771]

I check the CPU usage and find the application consumes more CPU usage when application running in background mode.
I am not sure if the option setting can improve CPU usage issue, could you please help?
This is my code for using background mode.

backgroundSetting() {
    if (this.globalvar.platform.is('android')){
      const options = {
        id: -1,
        title: 'Test',
        text: 'Running in Background Mode',
        hidden: false,
        silent: false,
        sticky: true,
        resume: true,
        foreground: true,
      };

      cordova.plugins.backgroundMode.setDefaults(options);
      cordova.plugins.backgroundMode.enable();
      cordova.plugins.backgroundMode.on('activate', () => {
        cordova.plugins.backgroundMode.disableWebViewOptimizations();
        console.log('background mode activate !!!');
      });

      cordova.plugins.backgroundMode.on('deactivate', () => {
        console.log("background deactivate xxxx ");
      });

    } else {
      cordova.plugins.backgroundMode.enable();
    }
  }
