Apple officially released iOS 18, bringing a range of new features and improvements to supported iPhone models. This update focuses on enhancing personalization and privacy, allowing users to tailor their Home Screen and Control Center layouts to their preferences. One standout feature lets users hide specific apps, securing them from unauthorized access.
The rollout of iOS 18 underscores Apple’s commitment to providing long-term software support, as even the five-year-old iPhone XR is eligible for the update. This ensures a broader spectrum of users can access its new functionalities without needing to upgrade their devices.

Limitations on Advanced Features
While iOS 18 introduces many useful features, some advanced functionalities like Apple Intelligence, which leverages artificial intelligence for enhanced user experience, are restricted. Specifically, Apple Intelligence requires devices with the A17 Pro or M1 chipsets. Therefore, only the latest iPhone 15 Pro and 15 Pro Max models can fully utilize this feature. Older iPhone models will not have access to it, which may influence users considering an upgrade.
How to Install iOS 18
Installing iOS 18 is straightforward. Users should:
- Open the Settings app on their iPhone.
- Navigate to General > Software Update.
- If iOS 18 is available, tap Download and Install.
- Follow on-screen instructions and wait for the update to complete.
The installation duration depends on internet speed and device model. Apple advises users to connect to Wi-Fi and ensure their iPhone has sufficient battery life to avoid interruptions.
Context of iOS 18 in Apple’s Update Cycle
Although iOS 18 has been widely adopted, Apple introduced iOS 26 as its latest system alongside the iPhone 17 series in late 2025. This new naming scheme reflects the release year, explaining why the update immediately succeeding iOS 18 is called iOS 26. Newer iPhone models including iPhone 11 through iPhone 17 remain compatible with iOS 26, although devices from older generations might experience performance slowdowns.
Despite the arrival of iOS 26, iOS 18 remains an important milestone for iPhone users who have not yet updated or own compatible devices. It highlights Apple’s focus on personalization, privacy, and sustained support for legacy devices, keeping the iPhone ecosystem robust and user-friendly.
For those using older models or considering device upgrades, the availability of iOS 18 ensures continued access to new features without immediate hardware replacement. Meanwhile, owners of the latest models can enjoy the full suite of advanced tools, especially those powered by cutting-edge Apple chipsets.
Users interested in verifying which iOS version is installed on their iPhone can do so by going to Settings > General > About and checking the Software Version entry. This helps ensure the device is up-to-date with the latest features and security improvements.
Overall, iOS 18 delivers meaningful enhancements catered to a wide audience, balancing innovation with broad accessibility. It is now available for download, empowering iPhone users to customize and secure their experience more effectively than before.
