Nokia Lumia 920 WindowsPhone 8 WP8 Battery drain because of background tasks

Over the last days, the battery of my Lumia 920 was empty much faster than i was used to. Usually it lasted y couple of days, but now its empty after 1 day.

I fixed it by disabled a couple of background tasks. I also found out, that some of those Background tasks were added by recently installed apps.

Go to Settings->Apps->Background Tasks to see the list of apps that work in the background and choose the ones the disable.
