In the battery management, there is an option to put the app in sleeping mode, which means when we enabled the option it supposed to control the background activity as and when the app not in use. Refer the screenshots which I shared, I enabled the setting in all the apps except few which we don't have the option to enable. But still you can see the app works in background. So the function "put the app to sleep" not at all works.
Samsung pls check this and resolve, if this works well the battery performance might increase.
Bro I did intense check on battery usage. I already put youtube app in restricted mode. but still it runs in background. not only this app, almost all the apps are running in background. so the programme for background restriction doesnt work.. see the attachment.
