What Apple says is new
Siri AI, Write with Siri, Visual Intelligence on the current screen, Photos Spatial Reframing / Extend / Clean Up, Safari tab topics and Notify Me, child-account Ask to Browse and Time Allowances, a Liquid Glass slider, and lab-measured performance notes versus iOS 26.6 on named devices. Features vary by language, region, and hardware. Server-side Intelligence features have daily limits.
Do this
- Install iOS 27 after a backup.
- If Software Update titles 27 as 26.7, read the 26.7 label bug.
- Battery collapsed? Has indexing finished?
- Siri still old? Waitlist and model download.
- Storage vanished? Intelligence storage.
- Ads on home Wi-Fi after 27? Connectivity Assist.
- iPhone 15 / 12 / 13 Pro Max: stay on 26.7 or update.
