iOS and iPadOS updates should generally be installed rather than deliberately skipped. Updates are not limited to adding new features; they also contain important security patches, bug fixes, performance improvements, compatibility updates, and changes designed to improve the overall reliability of the operating system.
For a normal iPhone or iPad user, there is usually little reason to remain on an older version simply to avoid an update. Keeping the operating system reasonably current helps ensure that the device, built-in apps, third-party apps, accessories, and online services continue to work properly and securely.
There can, however, be legitimate exceptions. For example, in software development, enterprise deployment, testing, or MDM-managed environments, an application or configuration may have been specifically designed and tested against a particular iOS/iPadOS version. In such cases, an immediate update may need to be evaluated before deployment because an OS change can alter APIs, system behavior, permissions, security requirements, or device-management functionality.
Even developers should not assume that their existing code will remain unaffected indefinitely. Apple periodically changes and enhances iOS/iPadOS, and those changes can expose dependencies on older APIs or assumptions made in the original code. Similarly, MDM configurations and profiles may occasionally require modification when Apple introduces new security controls, restrictions, enrollment mechanisms, or management capabilities.
Therefore, the better approach is not to avoid updates, but to test and validate them when you have a specialized environment. For ordinary personal use, keeping iOS/iPadOS updated is the recommended practice. For development and enterprise environments, updates should be incorporated into a controlled testing and deployment process before being rolled out broadly.

If you do not want to upgrade to iOS 27, because you do not need new latest features like Apple Intelligence, for example, you can still install iOS 26.7, which also adds some security updates to your device.
