The recent update addresses battery drain issues and prevents downgrading, with iOS 17.3 set to bring further security enhancements in January 2024.

Apple recently released iOS 17.2.1, a minor but significant update that contains crucial bug fixes and security updates.
The update has fixed a major ongoing bug on the iPhone, specifically addressing battery drain issues, which was a widespread issue for users after updating their iPhones to the previous iOS update.
Apple has also stopped signing iOS 17.1.1 and iOS 17.1.2, preventing users from downgrading from any subsequent update.
The release notes for the update did not mention the battery drain fixes for the North American market, but the issue has likely been resolved.
Apple is also working on the iOS 17.3 update, which will be released in January 2024, carrying new features that will enhance device protection and security.
