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, iOS 15.0.2. 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. It’ll likely be a 1GB+ download for iPhone 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 X that was previously running iOS 15.0.2.

iOS 15.1 Problems

iOS 15.1 is 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.

Apple stopped signing on iOS 15.0.2 which means you can’t 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 either.

Keep this in mind if you’re having a good experience on iOS 15.0.2 or older. Once you make the move to iOS 15.1, you won’t be able to go back.

The company says support is coming to apps like BET+, Disney+, ESPN, HBO Max, Hulu, MasterClass, Pantaya, Pluto TV, and Starz.

iOS 15.1 also brings 12 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 14.5 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’s confirmed a new version of iOS 15 and iOS 15.2 is currently in beta ahead of its public release. The company hasn’t confirmed a specific release date yet, but it should drop sometime before the end of the year.

If your problems on iOS 15 are really bad, or you just want to try new features, you can download the iOS 15.2 beta onto your iPhone right now.
