Bugzilla

Hello, I tried to investigate this issue using the welt.de site for a long time. For now, I tested the site using the Wifi service and after more than 20h those are my findings:
- Using Google Pixel 3 (Android 9) the usage data was ~ 100Mb;
- Using LG G7 fit (Android 8.1) the usage data was ~ 150Mb;
- Nokia 6 (Android 7.1.1) the usage data was ~ 900Mb;

The scenarios tried was:
- Using the site for a couple of hours(browsing on the site, watching some posts, playing some videos);
- Using the Browser while the site was opened on a different tab);
- Let the browser with the site on the background(also, let the phone opened on the night with the site opened);
- Using other apps while the browser with the site was on background;

From my investigation, I see that the site have a notification about the running of audio from the main page of welt.de on all scenarios presented above. In my opinion, is that the site runs that information in the background anytime when you use their site(what would make the app to use more data than normal). 
Also, I found a similar bug filed some times ago who is investigating the same behavior. On bug 1273552 you'll found more information and investigation about this problem.
