Hi everyone! Today, we are talking about New in iOS 18.1.1. This is the latest update from Apple, and it comes after iOS 18.1. Along with iOS 18.1.1, Apple also released updates for iPad OS, Mac OS, and Vision OS. These updates help keep your devices secure and working well.
Update Size
The size of the iOS 18.1.1 update is about 436.48 MB. However, this size can change based on your device and if you are updating from an older version.

Build Number
If you want to check the build number of the new update, you can find it in the settings. The build number for iOS 18.1.1 is 22B91.
What’s New in iOS 18.1.1?
Now, let’s talk about what’s new. If you have watched my videos before, you know that a double point update usually means there are no new features. This update is no different. Apple said this update only has important security fixes. It is recommended for all users to update.
So, if you had issues with saving photo edits, this update does not fix that. If you had app crashes, battery drain, or Wi-Fi issues, those are also likely not fixed. Apple seems to be waiting until iOS 18.2 for those bug fixes. This update is strictly for security patches.
Security Fixes
There are two main security fixes in this update:

- The first fix is for a JavaScript core bug. This bug could let bad web content run code on your device. Apple has improved checks to fix this issue.
- The second fix is for a WebKit bug. This bug could lead to a cross-site scripting attack. Apple has fixed a cookie management issue to improve security.
It’s important to note that even though these bugs were reported as being exploited on Intel-based Mac systems, they could also affect iPhones and iPads. So, it is crucial to update your devices for better security.
Performance and Battery Life
Now, let’s talk about performance. You should not expect any performance boost from the iOS 18.1.1 update. If you are coming from iOS 18.1, the performance will be similar. However, if you are still on iOS 18.0, you might see some improvements in battery life and performance.
Geekbench Test Results
I ran a Geekbench 6 test to see how iOS 18.1.1 performs. The single-core score was 3205 and the multi-core score was 7685. These results are very similar to what we saw with iOS 18.1.
Should You Update?
So, should you update to iOS 18.1.1? Yes, if you are on iOS 18.1 or an earlier version, it is a good idea to update. Even though you won’t see new features, you will be protected with the latest security patches.

For Beta Users
If you are currently using the iOS 18.2 beta, it is not worth downgrading to iOS 18.1.1. You will receive these security patches in the next beta update. They will also be included in iOS 18.2.
What’s Next?
What can we expect next from Apple? The next update will likely be iOS 18.2. There could be an iOS 18.1.2, but that would need a major bug to be found.
We expect iOS 18.2 to be released in early December. The possible dates are December 2nd or December 9th. After that, we won’t see iOS 18.3 until 2025.
Conclusion
