iOS 27: 30% Faster Apps, a New Siri, and Every Feature That Changes Your iPhone
From a rebuilt Siri to self-organizing Safari tabs, iOS 27 is the most feature-dense iPhone update in years - and it lands this fall.
Apple ships iOS 27 features this fall, and the list runs deeper than most annual updates. Three years of Apple Intelligence groundwork surfaces here in a version that touches Siri, the camera, the Photos app, Safari, and the system's core performance - all at once. Public beta testing kicked off in June with 12 changes. September is the likely release window. iPhone 11 and newer will run it.
Siri Gets Its Own App and Learns to Write Like You
Siri AI is the headline change. Apple rebuilt Siri from scratch at WWDC 2026, replacing the command-response model with a conversational assistant that can reason across multiple turns, follow up on earlier questions, and take action inside apps. Ask it to find a photo from a vacation three years ago, pull an email buried under 200 newsletters, or add a song from a nearby speaker to your playlist. Siri processes all of that using personal context stored on your device - messages, notes, photos, calendar - without routing the query to a server. No more rephrasing until it works.
A dedicated Siri app now collects every conversation in one place, synced across iPhone, iPad, and Mac. Start a question on your phone and return to the same thread on your laptop without restarting. Write with Siri extends the AI into virtually any text field - describe what you need in plain language and Siri drafts it. In Messages and Mail specifically, Siri can match your writing style, punctuation, and tone. That last part is the genuinely useful piece: not a generic draft, but one tuned to how you actually write.
Siri Mode in Camera Lets You Point at Anything and Ask
Siri mode turns the Camera viewfinder into a visual search interface. Point at a plant, a restaurant menu, a nutrition label, or a piece of equipment and tap - Siri pulls information about what it sees. Visual Intelligence powered a version of this on iPhone 15 Pro last year. iOS 27 brings it to the default Camera app on all compatible devices, accessible with a single tap from the viewfinder. No mode switch. No separate app.
Photos Gets Three AI Editing Tools That Work on Existing Pictures
Spatial Reframing is the one worth understanding first. Shoot a tight portrait, then reframe it as a wide shot after the fact - Apple's AI reconstructs the scene around the subject. Photographers who regularly crop too close have a genuine fix here. The Extend tool adds canvas to the edges of any photo, useful when the frame cut off something you needed. Clean Up, which removes unwanted objects from photos, covers larger areas in iOS 27 - bigger objects, cleaner results around the edges.
Image Playground gains a photorealistic generation mode alongside the existing illustration styles. Describe an image, pick photorealistic, and the app builds it from scratch. For most people the reframing and cleanup tools deliver more practical value than generation - Image Playground serves creators who want original images rather than fixes to existing shots.
Apple Published the Performance Numbers - 30%, 70%, 80%
App launches run 30% faster on iPhone 11 Pro Max. New photos load in the Photos library 70% faster on iPhone 15. AirDrop transfers move 80% faster on iPhone 16 Plus. Apple tested all three against iOS 26.4.2 under controlled conditions, and the footnotes specify the exact devices used - which matters, because gains will vary across the model lineup. On older hardware the improvements will be smaller. On iPhone 16 and 17 models, Apple fast-tracked a new chip architecture specifically to handle AI workloads alongside these system-level changes.
Liquid Glass, the translucent design language Apple shipped at WWDC, gets contrast and legibility refinements in iOS 27. Refraction is more uniform. App icons render with sharper detail. A new slider in Settings lets you tune how frosted or clear the glass effect appears - from fully tinted to nearly transparent. Network transitions also improve: the phone picks the best available Wi-Fi or cellular connection more aggressively, so calls and navigation hold their connection as you move between networks.
Safari Tabs Sort Themselves - Passwords Fix Themselves, Too
Safari groups open tabs by topic automatically - travel, shopping, reading - without any manual sorting. A Notify Me feature monitors specific pages for updates like a price drop or a product restock and pushes a notification when something changes. Both require no setup beyond enabling them.
Passwords adds automatic detection and repair of weak or compromised credentials. Open the app, see which passwords are at risk, tap to update - Passwords visits the site and submits the new credential on your behalf without you navigating there. Mail search gets a new relevance ranking system that surfaces the most pertinent result first, even when it is buried deep in the inbox. Shortcuts gains natural-language input: describe the automation you want and Shortcuts builds the workflow from your description.
Child Safety Controls Are the Most Complete Overhaul in Years
Ask to Browse requires children to request permission before accessing any new website. Parents receive a Messages notification with a preview of the site and tap to approve or decline - no need to be in the same room. Setup Assistant now walks parents through selecting which system apps a child's phone can access before handing it over: a small set, a recommended set, or a custom list. Communication Safety, which previously flagged nudity in shared images and videos, now also screens for gore and violent content.
Time Allowances set app-category budgets across entertainment, games, and social media, with age-based defaults developed with child development researchers. Parents can adjust from there. Schedules control which apps are available at specific times or days - school hours, bedtime, weekends. Apple redesigned the parental controls section of Settings to surface status at a glance and allow quick one-tap changes on the fly.
Eight More Features Worth Knowing Before Fall
Call Context surfaces relevant information during business calls - a confirmation code from Mail while talking to an airline, displayed automatically without switching away from the call. iCloud Shared Albums gains Android and Windows access through iCloud.com for the first time, plus full-resolution sharing and photo reactions. Cycle Tracking in Health adds perimenopause detection for users 40 and above, with symptom logging and educational resources built in. Maps Flyover uses Visual Intelligence models to render individual trees and architectural details in aerial imagery, replacing the blurred textures of earlier versions.
GymKit comes to iPhone for the first time, connecting to treadmills, ellipticals, bikes, and stair-steppers directly from the phone - no Apple Watch required. AirPods gain a Custom EQ for adjusting lows, mids, and highs in AirPods settings. Home adds AI grouping for related security camera notifications and natural-language search across HomeKit Secure Video clips. VoiceOver adds richer image descriptions and Action button integration; a new captioning feature generates synced subtitles for any video and can translate existing captions into other languages.
Most iOS 27 features land on iPhone 11 and newer. Siri AI - the conversational assistant requiring Apple Intelligence - needs iPhone 15 Pro, iPhone 15 Pro Max, or any iPhone 16 or 17 model. Siri AI ships in English first; other languages follow later this year. Apple has not announced the exact September date. The update is free.
