Apple has opened access to the iOS 27 public beta, giving compatible iPhone users an early look at the next major software cycle. This release puts the spotlight on Apple Intelligence, an upgraded Siri experience powered by AI, broader Liquid Glass customization, and performance improvements designed to make the system feel faster and more refined.
Although the public beta is now available, Apple's full release is still expected later in the year, likely in September. The beta is meant for testing, which means users may encounter unfinished features, unexpected glitches, or stability issues. Compared with the developer beta, the public version is generally more polished, but it still carries the usual risks of pre-release software.
What users should know before installing
Anyone planning to try the beta should create a local backup on a Mac or PC first. An iCloud backup made while running beta software can overwrite a previous stable backup, making recovery more complicated if a downgrade becomes necessary. A computer backup offers a safer path back to the current official version, though any data created after the backup will not be included.
Apple says all iOS 26-compatible iPhones can run iOS 27, including the iPhone 11 series, iPhone 12 series, iPhone 13 series, iPhone 14 series, iPhone 15 series, iPhone 16 lineup, iPhone 17 lineup, iPhone Air, and iPhone SE models from the second generation onward. However, Apple Intelligence features require iPhone 15 Pro or newer, while Apple's most advanced on-device models are limited to the iPhone 17 family and iPhone Air.
How the beta is installed
To join the public beta, users need to enroll their Apple Account in Apple's beta program, then go to Settings > General > Software Update > Beta Updates and select the iOS 27 public beta. The developer beta follows a similar path, but it is aimed at users who want the earliest builds and are comfortable with a higher testing profile.
As Apple continues refining iOS 27, the public beta offers a preview of a more intelligent and responsive iPhone experience. In the longer term, this rollout may help shape a more adaptive mobile ecosystem for everyday users.
