The third iOS 27 public beta 3 is now available for iPhone, offering early access to Apple's biggest software update of the year. Siri AI is the headline feature, rebuilt around Apple Intelligence. It can hold ongoing conversations, search personal info, and understand onscreen content. The beta also includes a redesigned Screen Time experience, Liquid Glass customization, and performance upgrades.

Performance gains are significant: apps can launch 30% faster, AirDrop transfers finish 80% faster, and new captures appear in Photos 70% faster. These optimizations extend to older devices like iPhone 11 and newer. Liquid Glass now offers a customization slider under Settings > Appearance for clarity and flexibility.

Screen Time gets a major overhaul with a new dashboard, Time Allowances, and Schedules for different routines. Communication Safety now detects violent content. To install, enroll in the Apple Beta Software Program and select iOS 27 Public Beta under Settings > Software Update > Beta Updates. Beta software may have bugs, so back up your device first.
