Apple has rolled out iOS 18.4 earlier than expected, delivering a suite of new features, critical security updates, and Apple Intelligence enhancements. With security vulnerabilities patched and performance improvements in play, iPhone users have a crucial decision to make: update now or wait?
Who Can Get iOS 18.4 and How to Install It
Apple’s latest iOS update is available for all devices starting from the iPhone XR, iPhone XS, and iPhone XS Max, covering every iPhone released since 2018. This includes the second- and third-generation iPhone SE and the newest iPhone 16 models.
To install iOS 18.4:
- Open Settings on your iPhone.
- Navigate to General > Software Update.
- Tap Download and Install.
Be prepared for a large file size—up to 3.76GB in some cases—so ensure you have enough storage and a stable Wi-Fi connection before updating.
New Features in iOS 18.4
This update introduces several enhancements, particularly for newer iPhone models. Apple Intelligence, the company’s AI-powered system, is now available in eight additional languages, broadening its accessibility.
Other key features include:
- New Emoji: Apple has added eight new emoji, expanding customization options for users.
- Photos App Improvements: Better search capabilities and organizational tools for managing media.
- Apple Vision Pro Integration: A dedicated app for users of Apple’s mixed-reality headset.
- News+ Enhancements: A stronger focus on food-related content and personalization.
While some of these upgrades cater specifically to iPhone 16 users, older devices will still benefit from general performance boosts.
Security Fixes: 62 Vulnerabilities Addressed
One of the most pressing reasons to update is security. iOS 18.4 addresses 62 different security vulnerabilities, including:
- WebKit Flaws: Fixes for issues affecting Safari’s core engine, preventing potential web-based attacks.
- Kernel Vulnerabilities: Security patches for iOS’s operating system to block exploits that could allow unauthorized access to device functions.
Given the severity of some of these vulnerabilities, Apple strongly recommends updating as soon as possible.
User Reactions: Mixed but Largely Positive
Initial user feedback has been largely favorable, though some concerns have emerged. A handful of iPhone owners reported faster battery drain, but others claimed improved performance instead. One user noted, “This is probably one of the best iOS 18 updates we’ve had so far… and I’ve actually noticed better battery performance.”
Some users also experienced longer installation times due to the update’s size, but no widespread performance issues have been reported yet.
Should You Update?
Considering the sheer number of security fixes, this update is a strong yes for anyone prioritizing security. The added features, while appealing, may not be revolutionary for all users. If you have an older iPhone and are concerned about performance, it may be worth waiting a few days to see if any major issues emerge. However, for most users, updating sooner rather than later is the best move.
