Ionic 4: BatteryStatus doesn't change

Issue

I am trying to get the battery status of the device in my app.

after having installed

cordova-plugin-battery-status
@ionic-native/battery-status
@ionic-native/core

I put BatteryStatus into the module providers.

In the component, I have :

batterySubscription: Subscription;
batteryLevel: number = 100;
isBatteryPlugged: boolean = false;

constructor(private batteryStatus: BatteryStatus) { }

ngOnInit() {
  this.initSubscriptions();
}

initSubscriptions() {
  this.batterySubscription = this.batteryStatus.onChange().subscribe( (status: 
  BatteryStatusResponse) => {
    console.log(status.level, status.isPlugged);
    this.batteryLevel = status.level;
    this.isBatteryPlugged = status.isPlugged;
  });
}

Everything compiled perfectly, but the battery informations never change (as well in the browser as in the app). It doesn't detect neither when I plug the computer nor when the battery level changes.

Has somebody an idea of the problem ? Thanks !

Solution

The code looks good to me, but that plugin is so old that it might not be working as expected on newer OSs. You can try and open an issue: https://github.com/apache/cordova-plugin-battery-status/issues

If I were you however, I'd try using capacitor: https://capacitorjs.com/docs/apis/device#getbatteryinfo
