  The design they describe is how you do anything on iOS that's going to go out and talk to some web services, otherwise talk on the network, or the like. You do your UI stuff on the UI thread and you use additional background threads for the network stuff. In any case, if you're not in the Facebook app, then iOS has frozen it and it's not getting any CPU time at all. Removing it from the multitasking tray does not stop it from consuming any CPU resources, because if Facebook isn't on the screen then it's not running.

  The Facebook iOS shouldn't be running once it's off your screen. I really loved the iOS app actually. I went from S3 to iPhone 5 to HTC One. The Android app was fine when I was on the S3, but it seemed to have gotten worse while I was on iOS. Battery usage on my HTC One has several times been double what my screen uses (very, very, very weird) even if I've swiped the app away from my recent apps after using it for maybe 10 minutes. Either way, I've always been amazed at how terrible a company like Facebook is at designing a coherent mobile experience. Their Symbian, Windows Phonee, Android, and iOS apps are all different from each other and just hit (recent iOS is mostly fine) or miss (all the others). I think they have a different team for each platform.
