    For example I'm using the YouTube app and then I decide to go on safari for like 5 minutes, then when I go back to the YouTube app, I can see a 'screenshot' of what I was doing last, me thinking good let me continue with what I was doing, then suddenly the app refreshes. When I had iOS 6 it would take a little bit more longer for this to happen and if I remember correctly, iOS 6 doesn't show you a 'screenshot' making you believe everything is still intact. btw I'm using an iPhone 4S.

    Simple answer. You have a two year device that is very capable, but has 512mb of RAM. This will make things refresh as they are no longer cached.

    Things of that nature also happen on iPhone 5 (and I'd imagine even 5S and newer iPads as well) with 1 GB of RAM.

    Yes. They would also happen if the iPhone had 4GB + RAM. It is just more noticeable on devices with less RAM...

    This constant refreshing and limited cache is UNBEARABLE on the iPad mini, specially since I use the iPhone 5.

    Right, so it's not really a "simple answer" essentially.

    No it still is. Limited RAM = limited cache = refresh

    Is its problem also due to apps not properly supporting state restore?

    Happens also on iPhone 5s. I don't think it is a RAM issue, just the last image for that app being displayed, while the app itself has now closed. They could fix this fairly easily in an update.

    It doesn't really address some of the things the OP brought up, like it seemingly not happen as much in iOS 6 and it not being as misleading given that the screenshot almost serves no purpose in cases like that.

    The more resource intensive the task the more RAM the system uses. So on iOS 6 there is less RAM the system uses compared to 7. Don't quote me on this, but it seems the preview itself is stored in RAM. If true, that's a big hog right there if too many apps are open.

    It's a good question. It happened on my mini under 6 and happens more with 7. Hope you're right.

    I thought it has been this way since iOS 4. I refer to how it shows you where you left off while it tries to recover. Perhaps your device is too slow or the way you use it make it run out of RAM often.

    The OP didn't say it happened less in iOS 6. He said the refresh delay was slightly longer.

    iOS 6 didn't even give screenshots.

    Anyways I just tested it on my iPhone 5 with Facebook, Twitter, and YouTube and they all were little to 0 lag when switching back to them.

    I think it might be more of the iPhone 4S is older, but since some people are saying that it's even happening on the iPhone 5S, try closing all heavy apps like games or camera apps (I've noticed that sometimes Snapchat or other apps where the camera is still open will actually cause my phone to heat up, though the battery stays the same) and see if that helps. I hardly ever have open an app that uses more power than Skype or YouTube so maybe it's just the apps I'm using aren't using many resources.
