Why are my iOS app's session lengths 30 min + in Google Analytics?

Question

More importantly, how do I fix it?

It\'s as if backgrounding the app doesn\'t end the session.

Answer 1

It says if the user has an event with in 30 mins it will treat it as the same session. So all it means is if the user came back within 30 minutes of using your app.
