When you fire up an app like Instagram, it does many things that create various drains on the battery. It opens the camera repeatedly when I don’t intend to use it, for instance. When you click stories, it opens the camera, often facing you. Who’s to say it doesn’t send that pic or some analysis of it to FB? I don’t think that would use any significantly higher battery or network anything especially since the processing and data transfer could be deferred.
