iOS 27 public beta is now available for iPhone, offering early access to Apple's biggest software update. The headline feature is Siri AI, rebuilt around Apple Intelligence for conversational assistance, onscreen awareness, and cross-app actions. It requires an iPhone 15 Pro or newer.

Performance gains extend to older devices: apps launch up to 30% faster, AirDrop transfers complete up to 80% faster, and photos appear up to 70% quicker. The Liquid Glass design gains a customization slider under Settings > Appearance, while Safari, Photos, Passwords, and Shortcuts receive new AI tools.

Screen Time gets a major parental-control overhaul with category limits, schedules, and Ask to Browse for websites. Communication Safety now detects gore and violent content. The beta supports iPhone 11 and newer plus SE (2nd gen+), though advanced on-device features need iPhone 17 Pro or iPhone Air.
