Use a Smart Focus Mode
Focus Modes are a great way to silence distracting notifications when you want to get some work done. While you can manually create as many Focus modes as you wish, Apple Intelligence can also filter out the notifications for you.
With Apple Intelligence, there’s a new Reduce Interruptions Focus mode, which will use AI to allow important notifications to interrupt you while silencing all other notifications that your iPhone thinks aren’t as important. Of course, you can still manually tell your iPhone which notifications you want to block or receive, regardless of what Apple Intelligence decides.
This works as a stand-alone Focus mode, and as an extra feature for any Focus mode, you already have.
If you want Apple Intelligence to reduce interruptions in existing Focus modes, you’ll need to go to Settings > Focus and then choose the Focus mode you wish to change. From there, tap on Intelligent Breakthrough & Silencing to let Apple Intelligence analyze and filter your notifications.
On the other hand, if you want to use this feature as a Focus mode, go to your Control Center, tap the Focus control, and choose Reduce Interruptions.
