5 Things to Know About the iOS 17.1.1 Update [u]
Apple’s pushed a new iOS 17.1.1 update to iPhone users in an effort to fix some of the more glaring bugs affecting the operating system.
iOS 17.1.1 is now available to download if you own a compatible iPhone model. All iOS 17-powered iPhones are compatible with iOS 17.1.1.
The iOS 17.1.1 update is a point upgrade which means it’s smaller than its predecessor (iOS 17.1) and the software that will probably replace it (iOS 17.2).
While small, the firmware is an important release and most iPhone users will want to install it today or at some point in the near future.
11/15 Update: Apple has closed the downgrade path back to iOS 17.1 and we’ve updated our guide to reflect the change.

With that in mind, we want to take you through iOS 17.1.1’s changes, offer some thoughts about the software’s performance, highlight the iOS 17.1.1 problems plaguing the iPhone, and more.
We’ll start with a quick look at iOS 17.1.1’s performance.
iOS 17.1.1 Review
If your iPhone’s currently running iOS 17.1, you’ll see the smallest iOS 17.1.1 download size. It’s a 314MB download for the iPhone 12 Pro. Unless your iPhone is running low on storage, you won’t have to make room for the download.
The iOS 17.1.1 download size depends on your iPhone model and the version of iOS it’s currently running.
If your phone is running a really old version of iOS, you’ll see a larger download. In some cases, much larger. That’s because the iOS 17.1.1 update includes the changes from any iOS updates you skipped.
As for the installation, it took about eight minutes to complete on an iPhone 12 Pro that was previous running iOS 17.1. If your iPhone is running older software, it may take longer.

iOS 17.1.1 Problems
We haven’t noticed any major issues with the software, but the firmware is causing problems for iPhone users. Some problems are brand new, others have carried over from previous versions of iOS 17.
The current list of iOS 17.1.1 problems includes abnormal battery drain, Bluetooth issues, installation issues, Exchange issues, and problems with first and third-party apps.
If you run into a problem with the software, take a look at our list of fixes for the most common iOS 17 problems. We’ve also released tips that could help you improve your phone’s performance and tips that could help fix battery life issues.
Apple recently stopped signing on iOS 17.1 which means you can’t drop your iPhone’s software back to older software if iOS 17.1.1 starts causing problems. Keep this is mind if you haven’t upgraded yet.

iOS 17.1.1: What’s New
Apple’s point updates (iOS x.x.x) typically focus on fixing problems within the operating system and that’s exactly what iOS 17.1.1 brings to the table.

iOS 17.1.1 fixes two problems:
- In rare circumstances, Apple Pay and other NFC features may become unavailable on iPhone 15 models after wireless charging in certain cars
- Weather Lock Screen widget may not correctly display snow
iOS 17.1.1 doesn’t have any new security patches on board.
iOS 17.1.1 Jailbreak
If you still jailbreak, make sure you avoid the iOS 17.1.1 update
We don’t expect developers to release a public jailbreak tool that’s compatible with iOS 17, or iOS 17.1.1, today. If you still jailbreak your iPhone(s), keep an eye out for new information in the weeks ahead.
What’s Next
Apple’s currently working on a new iOS 17.2 update and the software should arrive later this year, probably in December ahead of the holidays.
If you can’t or don’t want to wait that long, you can download a pre-release version of iOS 17.2 onto your iPhone via Apple’s beta program.
