ionic background mode not working when phone is unplug in android 10+

[YSoni89]

I am trying to use this plugin for one of my use case. I need to run some processes in background when app (built in ionic 5 and angular 10) is minimize and screen is locked. I am using Samsung X cover Android 10 + version. Its working fine for longer period of time (approx. 14-15 hours) if I plugin my phone (USB cable charging on), minimize the App with screen lock but it does not give similar results if I unplug the phone from charger. App stop the background processes after 2-3 hours.

Can you please advice here?

Below is the code implemented ->

On device platform ready => below code is written
this.background.setDefaults();
this.background.enable();
this.background.on('activate').subscribe(() => {
this.background.disableWebViewOptimizations();
this.background.disableBatteryOptimizations();
});

I tried using "cordova-plugin-power-optimization": "0.0.4" => this.powerOptimization.RequestOptimizations();
this.powerOptimization.IsIgnoringBatteryOptimizations();
along with above options.

Permissions are set in my AndroidManifest.xml file such as -
android.permission.WAKE_LOCK,
android.permission.FOREGROUND_SERVICE
android.permission.REQUEST_IGNORE_BATTERY_OPTIMIZATIONS

Using latest versions of backgroundmode plugin - "cordova-plugin-background-mode": "^0.7.3",
