iOS keeps closing background apps very quickly (iPad2)

Hello!

You view article in Flipboard, click on share to Pocket, view the Pocket and email the article from there. When you are back to Flipboard, it's already closed and restarts.

You want to copy data between tabs in Safari. It is nearly certain that if the tabs contain complex web pages, Safari will forget them to save memory once you switch even once. The web pages are sometimes quite simple ones, too. One particular example are bank pages, which are not so complex. And as for the example copying, you might want to copy the destination account number into such page, when you make a transfer.

How to gain certainity, that:

- 3 tabs in Safari will close after no less than 10 minutes,

- 3 recent apps will close after no less than 10 minutes?

On iOS 4, the problem appeared when # of tabs was ~6. Now it's much quicker. I cannot recall how it was about closing applications.

On iOS 6, the applications were closing quickly too. I think iOS 5 was better at this.
