iOS 27 ships with full Siri AI, on-device video captions, tuning for old iPhones
APPSO · wechat · 2026-09-15
Apple has released iOS 27 to all users, supporting down to iPhone 11 and SE2. The headline feature is the new Siri powered by Apple Intelligence: it understands complex natural language, reads on-screen context, and chains multi-step cross-app commands (e.g. navigate to an address mentioned in a text), plus a dedicated visual intelligence entry in the camera app.
AI imaging also improves: cleaner object removal, Extend (outpainting) and Reframe (edge-side preview + cloud-completed viewpoint shifts), offline on-device video captioning discovered in testing, and realistic image generation in Playgrounds.
Non-AI highlights: an adjustable Liquid Glass slider for readability; app cold starts up to 30% faster, high-res photo loading 70%, AirDrop 80%; the long-requested Chinese-holiday-aware alarm; customizable camera UI, new photo views, frame export, AirPods custom EQ. Upgrade advice: iPhone 14+ should upgrade; iPhone 11-13 already on iOS 26 should too; older-device users staying on iOS 18 may want to skip. The full Siri experience remains unavailable in mainland China.
