5 Things to Know About the iOS 15.1 Update



Apple’s finally pulled the iOS 15.1 update out of beta and it’s now available to download.

iOS 15.1 is compatible with all iOS 15-powered phones, a list that includes the iPhone 6s, iPhone 6s Plus, iPhone SE, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus, iPhone X, iPhone XS, iPhone XS Max, iPhone XR, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone SE 2, iPhone 12 mini, iPhone 12, iPhone 12 Pro, iPhone 12 Pro Max, and the new iPhone 13 series.

Unlike the previous version of iOS 15 (iOS 15.0.2), iOS 15.1 is a milestone upgrade and it’s a much larger update than its predecessor. It brings a mix of new features, fixes, and enhancements to the iPhone.

With that in mind, we want to take you through everything you need to know about Apple’s new iOS 15.1 update for iPhone.

In this walkthrough we’ll take you through all of iOS 15.1’s changes, the software’s performance, iOS 15.1 problems, the iOS 15.1 jailbreak status, and more.

We’ll start with some quick thoughts on iOS 15.1’s performance.

iOS 15.1 Review

If your iPhone is currently running iOS 15.0.2, you’ll see the smallest iOS 15.1 download size.

For iOS 15.0.2 users, the iOS 15.1 download is fairly large. iOS 15.1 is a 1.41 GB download for iPhone 12 Pro users moving up from the previous version of iOS 15.

The exact iOS 15.1 download size depends on your iPhone model and the version of iOS it’s currently running. So if your iPhone is running an older version of iOS, you’ll see a bigger download because your iOS 15.1 update includes the changes from iOS updates you skipped.

If you’re moving up from iOS 15.0.2, the installation process should take less than 10 minutes to complete. It took about seven minutes to install on an iPhone 12 Pro and an iPhone X that were previously running iOS 15.0.2.

We’ve been using iOS 15.1 on a few iPhone models for a very short time and here’s what we’ve learned about the software’s performance thus far:


  • Battery life is currently stable.
  • Wi-Fi connectivity is fast and reliable.
  • Bluetooth is working normally.
  • GPS and cellular data are both stable.

App Performance

  • Third-party apps including Netflix, Dark Sky, Twitter, Slack, Asana, Gmail, Chrome, and Spotify are working fine at the moment.
  • First party apps like Safari, Podcasts, and Calendar are also stable.


  • iOS 15.1 feels as fast as iOS 15.0.2.

If you’re running into bugs or performance issues on iOS 15.0.2 or an older version of iOS, you might want to install the iOS 15.1 update on your iPhone right now.

iOS 15.0.2 Problems

iOS 15.1 is already causing problems for some iPhone users. Some of these problems are brand new, others have carried over from iOS 15.0.2 and older versions of iOS.

The current list of iOS 15-related issues includes installation issues, UI lag, Exchange issues, problems with first and third-party apps, hotspot problems, touchscreen issues, issues with Touch ID and Face ID, charging issues, and stuttering.

If you encounter a problem on iOS 15.1, have a look at our list of fixes for the most common iOS 15 problems. We’ve also released tips that could help you improve your phone’s performance and some tips that could help fix bad iOS 15 battery life.

Apple is currently signing on iOS 15.0.2 which means you can drop your phone’s software back to the previous version of iOS 15 if iOS 15.1 is causing problems.

You can’t downgrade to anything older than iOS 15.0.2 so keep that in mind if you’re having a good experience on iOS 15.0.1 or older. Once you make the move to iOS 15.1, you won’t be able to go back.

We expect Apple to release new iOS 14 software in the near future so eventually you should be able to move your iPhone back to the previous operating system.

iOS 15.1 Update: What’s New

iOS 15.1 is a milestone upgrade, the first for iOS 15, and it brings some notable changes to the iPhone. Here’s the full list of changes on board:

  • Shared controls give everyone the ability to pause, play, rewind or fast forward.

  • Setting to turn off automatic camera switching when taking macro photos and videos on iPhone 13 Pro and iPhone 13 Pro Max.

  • New automation triggers based on the current reading of a HomeKit-enabled humidity, air quality, or light level sensor.

iOS 15.1 also brings new security patches to iPhone and you can read about those right here.

iOS 15.1 Jailbreak

The developer teams behind the Checkra1n and unC0ver jailbreaking tools have released versions that are compatible with newer versions of iOS 14, but only Checkra1n (currently in beta) is compatible with iOS 14.5. They don’t support iOS 15.1, iOS 15.0.2, iOS 15.0.1, iOS 15.0, iOS 14.8, iOS 14.7.1, iOS 14.7, iOS 14.6, or iOS 14.5.1 yet.

The newest version of unC0ver is compatible with newer iPhones including the iPhone 12 series. That’s big news if you’ve been waiting to jailbreak your new phone. Unfortunately it’s only compatible with versions up to iOS 14.3.

There’s no way to downgrade your phone’s software to iOS 14.3 or older versions of iOS which means you’re out of luck if you upgrade, or you already upgraded to newer iOS software.

What’s Next

Apple hasn’t confirmed a new version of iOS 15 so it’s unclear when the next version will roll out.

We expect the company to put a new version of iOS 15 into beta testing soon so we’ll let you know when we learn more about Apple’s future plans.
