Focus isn't the biggest feature to change with iOS 27, but it has some cool enhancements worth knowing.
One of the best tools your iPhone offers to help you avoid distractions is Focus, which lets you control which alerts arrive at what times.
To select a Focus mode, swipe down from the top-right of the screen to open Control Center, then tap the Focus panel and select the desired mode from there. To configure your Focus modes, go to Settings, scroll down to Focus, then select any option to tweak what's allowed and what's silenced.
While Focus has been around for several years, some of iOS 27's improvements include tweaks to the feature.
With Control Center opened, long-press on any empty part of the screen until edit mode activates. Drag the bottom-right corner of the Focus icon to resize it as desired.
IOS 27 also brings improvements to Focus mode tracking that allow you to build better Shortcuts around them. As explained by Derek Seaman, Shortcut actions can check your specific phone state based on the Focus mode that's now active. You can now select Sleep Focus mode for an automation trigger, too.
"Otherwise if" logic statements are now supported with Shortcuts and Focus mode triggers.
You can use natural language commands to have Siri create a Shortcut that includes Focus mode status integrated to it, now improved with iOS 27.
