One is the next-gen update and the other, iOS 17.7, is for those who want to keep their iPhones safe but would rather wait to roll out the first version of a new release.

iOS 18 has a built-in Game Mode that limits background activity on your iPhone so your games run more smoothly. You don’t need to do anything to enable it except launch a game: You’ll see a Game Mode notification at the top (tap this if you want to turn it off).
