On mobile, iOS will aggressively swap out webpages that haven’t been looked at in a while, though it still maintains the presence of the tab in the window. Navigate back to a paged out tab and it will force a page reload.

The swapping behaviour seems to be good at stopping leaky sites from ruining your browsing experience.

Personally I am also guilty of using tabs like bookmarks. Especially on mobile. Though I do think that if the aggressive swapping wasn’t done, this behaviour wouldn’t be so prevalent.
