Apple releases updates for the iPhone throughout the year, with a major update every fall. The major update is timed with the release of that year’s iPhone range.

Well, iOS 17.4 is here, with tweaks to autocorrect, and many other requested features.

This begs the question: How do you update your iPhone to iOS 17.4, and what do those updates do?

The smaller updates introduce new features that didn’t make it into the major release, as well as security patches and bug fixes.

Major updates, on the other hand, provide a comprehensive overhaul, transitioning your iOS from an older version to the latest one.

You can manually update iOS on your iPhone or let the iPhone do it automatically. The best way to keep your iPhone secure from attack is to keep it updated, so we’ll show you how.
