Want early access to Apple's newest features before the official release? Installing the iOS 27 Beta lets you test upcoming changes, explore new tools, and experience Apple's latest innovations months ahead of other users.
Whether you're interested in the Developer Beta or the Public Beta, this guide explains how to install iOS 27 Beta safely, what to do before upgrading, and how to remove the beta if you decide to return to a stable version.

Before Apple releases a new iOS version to the public, it goes through a beta testing phase. During this period, selected users can install preview versions of the software and help identify bugs and performance issues.
Apple typically offers two types of beta releases: Developer Beta and Public Beta. Both provide access to upcoming iOS features, but they differ in stability and release timing. If you rely on your iPhone every day, the Public Beta is usually the safer choice.
Installing beta software has both advantages and disadvantages.
Benefits■ Access new features before official release ■ Test redesigned apps and interfaces ■ Experience performance improvements early ■ Help Apple improve the final version |
Potential Risks■ App compatibility issues ■ Faster battery drain ■ Unexpected crashes ■ Missing functionality in some apps |
For most users, installing the beta on a secondary device is recommended.
Taking a few precautions can prevent headaches later.
As the iOS 27 beta version is not stable and with small bugs, it is highly recommended to back up your iPhone data before you get the iOS updated.

Beta updates can be large. Removing unused apps and large media files can help avoid installation failures.
A reliable Wi-Fi connection is recommended for downloading beta software.
