5 Things to Know About the iOS 12.0.1 Update



Apple is rolling out the first update to its iOS 12 operating system and the iOS 12.0.1 update brings bug fixes for some of the problems plaguing the iPhone, iPad, and iPod touch.

After a bit of a wait, Apple’s finally rolling out a new version of iOS 12. Dubbed iOS 12.0.1, it’s a small maintenance release for all iPhone, iPad, and iPod touch models capable of running Apple’s new operating system.

The iOS 12 update is much smaller than the first version of iOS 12, but it’s still an important release. The update comes with several key bug fixes including one for a widespread iPhone XS charging issue.

In this guide to the iOS 12.0.1 update we’ll take you through the most important things you need to know as we push away from the release date.

Our walkthrough includes a look at the iOS 12.0.1 update’s known changes, iOS 12.0.1 problems, iOS 12.0.1’s performance, and what’s next for iOS 12 users.

iOS 12.0.1 Reviews

The iOS 12.0.1 update is a very small download for iOS 12 users. If you’re currently running iOS 12.0, you’re looking at a 75+MB download. If your device is connected to a high-speed Wi-Fi network you should be able to download the iOS 12.0.1 update in a matter of seconds.

Once the download is complete, the installation should take no longer than 10 minutes to finish. It took around five minutes on the iPhone X and iPhone XS and right around seven minutes on the iPhone 5s.

If you’re currently running iOS 11, you can expect your download and installation to take a lot longer. The features, enhancements and fixes from iOS 12.0 are baked into your iOS 12.0.1 update.

For more on the download and installation, take a look at our guide to the download and installation.

We’ve been using the iOS 12.0.1 update on a handful of devices for a few weeks now and here are some of our initial thoughts about iOS 12.0.1 and its performance.


  • Battery life is normal on all of our devices.
  • Wi-Fi is stable and fast.
  • Bluetooth is working properly.
  • GPS and cellular data are both functioning normally.


  • Core apps including Twitter, Slack, Asana, Gmail, Chrome, and Spotify are working fine.
  • First party apps like Safari, Podcasts, and Calendar are stable.
  • Google Hangouts continues to crash.


  • iOS 12.0.1 is as fast as iOS 12.0.

If you’re dealing with iOS 12 problems you should install the iOS 12.0.1 update right now. If you’re having a good experience on the first version of iOS 12, you might want to hold out and wait for long-term feedback to emerge.

If you need iOS 12.0.1 feedback, take a look at our reasons to, and not to, install the iOS 12.0.1 update on your iPhone, iPad, or iPod touch right now.

We’ve also published our mini iOS 12.0.1 reviews for the iPhone XiPhone 7, iPhone 6siPhone 6, iPhone 5s, and iPhone SE with more on the way.

iOS 12.0.1 Update: What’s New

The iOS 12.0.1 update’s change log is small and comes with two security patches for potential lock screen exploits and a few bug fixes for iPhone XS and iOS 12 problems:

  • Fixes an issue where some iPhone XS devices did not immediately charge when connected to a Lightning cable.
  • Resolves an issue that could cause iPhone XS devices to rejoin a Wi-Fi network at 2.4GHz instead of 5GHz.
  • Restores the original position of the “.?123″ key on the iPad keyboard.
  • Fixes an issue where subtitles may not appear in some video apps.
  • Addresses an issue where Bluetooth could become unavailable.

Note that a few highly anticipated iOS 12 features are missing.

Apple pulled its new Group FaceTime calls feature from the iOS 12 beta a few weeks ago, but the feature will arrive inside the iOS 12.1 update this fall.

Also missing are the new emoji characters Apple promised with iOS 12. The new emojis are also available in iOS 12.1 beta and will be released with the final version of the update this fall.

iOS 12.0.1 Problems

The iOS 12.0.1 update didn’t go through a beta and problems have slipped into the final release.

We’re hearing complaints about download issues, battery drain, Wi-Fi connectivity problems, Bluetooth issues, and problems with Face ID.

If you’re noticing iOS 12.0.1 problems on your iPhone, iPad, or iPod touch you’ll want to take a look at our list of fixes for the most common iOS 12 problems. We’ve also released tips to improve iOS 12 performance and some tips to improve iOS 12 battery life.

If you can’t stand iOS 12.0.1’s performance on your device you’re stuck until Apple rolls out a new version of iOS 12.

Apple’s no longer signing off on iOS 12.0 which means you can no longer downgrade your device to the previous version of iOS 12.

Unfortunately, there’s no way to drop back down to iOS 11 either.

iOS 12.0.1 Jailbreak

Developers haven’t released a public iOS 12 jailbreak tool and it could be weeks before we see one.

As of right now, the only way you can jailbreak a device running iOS is if it’s running an older version of iOS 11. Unfortunately, there’s no way to downgrade to anything older than iOS 12.0.

We’ve seen an iOS 12 jailbreak proof of concept (and some fakes) emerge so those of you interested in jailbreaking your device should be on the lookout for fakes as we push through the year. We’ll probably see several more.

For now, jailbreak users need to skip iOS 12.0.1 and remain on earlier versions of iOS 11. For more on the jailbreak, take a look at our guide to the iOS 12 jailbreak.

What’s Next

Apple might be working on iOS 12.0.2, but it hasn’t confirmed the release. At this point, an iOS 12.0.2 update seems unlikely.

The only known update in Apple’s pipeline right now is the iOS 12.1 update which is slated to launch sometime later this year. We expect it to debut in late October or early November.

The iOS 12.1 update is currently in beta for all iOS 12-powered devices and we expect it to deliver a nice mix of new features, bug fixes, and security patches.

Fortunately, Apple's patched up the issue. If you skipped it, you'll probably want to move to iOS 12.5.1 soon.

The iOS 12.0 update delivered 16 patches for security issues. You can read about all of them over on Apple's security page.

In addition to those patches, iOS 12 delivers new security features aimed at protecting you and the data you store on your device. These include:
