Apple’s new on-device AI Siri in iOS 27 is presented as a phone-changer: it reads and reasons over private data in Mail, Messages, Notes, Photos, Calendar, Files and more (all kept on the device), answers natural questions about your life, and operates apps by voice. The tester ran 125 practical tasks to measure reliability and found most succeeded - Siri pulled flight numbers, calendar details, specific emails and photos, totals and averages from spreadsheets, and even inferred locations from photo geodata. It supports compound commands (add tracking numbers to reminders and send emails), creates images via Image Playground, drafts and proofreads messages, edits dictated text by voice, and can add identified songs to playlists. Apple’s staged rollout uses a waiting list.
The experiments also reveal limits: Health app integration is incomplete (no steps query; medication reminders go to Reminders, not Health), some UI actions fail (unsubscribe, favorite photos, delete apps), audiobook chapter skipping and some shortcut triggers don’t work, and a few voice-timing requests (10-second countdown) misbehave. Overall, the new Siri replaces many routine searches and assistant workflows by surfacing facts from scattered personal data and automating phone tasks, dramatically speeding common chores while remaining imperfect in specific system integrations and UI manipulations.
