iOS 12 just hit a milestone: it’s now installed on more than three-quarters of compatible devices. That’s a lot of iPhones and iPads.

As you can see from the graph below, users have been updating their devices in droves since iOS 12 (orange line) first released back in mid-September. Ten weeks later and its adoption rate hit 75% – that’s several weeks faster than iOS 11 (blue line) hit the same milestone last year. As you can see, iOS 11 reached a peak of more than 90% last Summer, and it looks as though iOS 12 is set to follow an even faster course.

This bodes well for Apple, for whom regular software updates are one of the key selling points of its ecosystem. Unlike Android smartphones, which are made by a number of different manufacturers with no direct link to the software chain, Apple supports its devices with the latest software for five years after release. The majority of Android devices would do well to stay up-to-date for even two years.

If you’re part of the minority that hasn’t updated yet, there are plenty of good reasons to do so. iOS 12 introduced several new features: Screen Time, allowing users to track their device usage and set limits to help curb those social media addictions; Siri Suggestions, customizable actions that can be created in the new Shortcuts app and triggered with your voice; Group FaceTime, allowing up to 32 people to video chat simultaneously. And who could forget the face-tracking fun of Memoji?

There are plenty more features and improvements that came with iOS 12, and besides all that it’s worth updating just to ensure you have the latest bug fixes and security patches. Running an older version of iOS makes your device more vulnerable as it doesn’t include the very latest protections against hackers and other cyber threats.

Updating is much easier than it used to be, too: simply head to Settings > General > Software Update and follow the instructions.
