Even if you don’t plan on buying a new iPhone, you’ll be able to get a bunch of new features next week. Apple plans on releasing iOS 12, the next major version of iOS, on Tuesday, September 17th.

As always, iOS 12 will be available as a free download. If your iPhone or iPad runs iOS 11, you’ll be able to update to iOS 12 as Apple plans to keep supporting all existing iOS 11 devices.

Here’s a quick rundown of what’s new in iOS 12. The main feature of iOS 12 is a performance improvement, especially for older devices. If you have an iPhone 6 or an iPad Air for instance, you should see a big improvement when it comes to launching apps, triggering the camera and entering text.

The other big theme of the year is new features to help you spend less time using your phone. There’s a new Screen Time feature to see and control how much time you spend using each app. Notifications are now grouped and you can silence them from the lock screen. You also can turn on Do Not Disturb when you’re in a meeting, for a few hours or for longer.

Apple didn’t stop there, and added new power features as well. Developers will be able to take advantage of a new file format for augmented reality and new features in ARKit 2.0. Apple is releasing the Workflow app as a new Siri Shortcuts app. Developers will be able to add information to Siri, as well, so that you can add a boarding pass or a music playlist to Siri.

The Photos, News and Stocks apps have been improved, as well as Apple Books (the app formerly known as iBooks). Apple is introducing Memoji on the iPhone X. It’s a customized avatar that you can use in iMessage and FaceTime to represent you.
