With iOS 18 now available in public beta, adventurous iPhone users who are not developers might want to try out the new operating system on their devices. The iOS 18 public beta provides early access to exciting new features such as dark mode icons and widgets, the Passwords app, a revamped Photos app, iPhone Mirroring on Mac, numerous AI Apple Intelligence features, and more.

If you're okay with the risks that come with using beta system software, installing the iOS 18 public beta is quite straightforward.

Should I install the iOS 18 public beta on my iPhone?

It's important to remember that beta system software can be quite buggy.

Although the public beta of iOS 18 is open to everyone, it's best suited for advanced users who are comfortable with beta software.

Beta system software is more likely to crash, have app incompatibilities, cause battery drain, and other performance issues, making it unsuitable for casual users on a critical-use iPhone.

There are advantages to running the iOS 18 public beta, such as experiencing new features before the official release in the fall. You can also use the Feedback app to report bugs and provide feedback on features and apps.

Always backup your iPhone to a computer and iCloud before installing any iOS 18 public beta.

Which iPhones are compatible with iOS 18?

iOS 18 is compatible with the iPhone 15, iPhone 15 Plus, iPhone 15 Pro, iPhone 15 Pro Max, iPhone 14, iPhone 14 Plus, iPhone 14 Pro, iPhone 14 Pro Max, iPhone 13, iPhone 13 mini, iPhone 13 Pro, iPhone 13 Pro Max, iPhone 12, iPhone 12 mini, iPhone 12 Pro, iPhone 12 Pro Max, iPhone 11, iPhone 11 Pro, iPhone 11 Pro Max, iPhone XS, iPhone XS Max, iPhone XR, and iPhone SE (2nd generation or later).

In essence, any iPhone newer than the iPhone XR can run iOS 18.

How to Install & Run the iOS 18 Public Beta on Your iPhone

Some users have noted that installing the iOS 18 beta can take longer than a typical software update (more on this later), so be prepared for potentially slow installation times.

1. First and foremost, backup your iPhone/iPad to iCloud, and also to a Mac using Finder, or to a Windows PC – do not skip this step.

2. Visit http://www.miracleart.cn/link/2a3500f75bcde2b99b4999f34133a1d2 and sign up your Apple ID for the iOS 18 public beta program.

3. Open the "Settings" app on your iPhone or iPad.

4. Navigate to "General" then "Software Update," and tap on "Beta Updates."

5. Choose 'iOS 18 Public Beta' from the available options, then go back to the standard Software Update screen.

6. The iOS 18 Public Beta should appear soon; tap on "Download and Install" to update your iPhone to the iOS 18 public beta.

The iOS 18 beta installation process involves downloading the software, verifying it with Apple, preparing the iPhone for installation, and finally restarting the iPhone to complete the iOS 18 update. The duration of this process can vary significantly due to various factors and even random or unknown conditions.

Once the iOS 18 public beta is installed, your iPhone will restart normally.

Updating to New iOS 18 Beta Versions

Subsequent iOS 18 beta updates will arrive like any other software update, accessible through Settings > General > Software Update.

Typically, Apple releases a new beta version biweekly.

The final version of iOS 18 will be released in the fall, and you can update directly from the beta versions once it's available.

How to Uninstall iOS 18 Beta if You're Unhappy with It

If you backed up your iPhone to a computer before installing the iOS 18 beta – whether it's a Mac or PC – you can revert to iOS 17 by restoring from that backup.

Remember, iPhone backups are not backward compatible, meaning an iOS 18 beta backup won't work for restoring to an iPhone running iOS 17.

iOS 18 Beta Installation Taking a Long Time

Many iPhone users have reported that installing the iOS 18 beta can take a very long time, and iPad users have experienced similar delays with the iPadOS 18 beta.

You may see the "Software Update" screen stuck on "Verifying" or "Preparing..." for an extended period.

Keep your iPhone plugged into a charger and let the installation finish – it will, but it might take several hours.

iOS 18 Beta Update Stuck on Apple Logo and Loading Screen

There have been widespread reports of iOS 18 beta installations taking an unusually long time, sometimes several hours, before they are complete.

Personally, I had to wait over 3 hours for the iOS 18 beta to finish installing on my device, with the iPhone stuck on a black screen displaying the Apple logo and a seemingly frozen loading indicator. However, the installation did eventually complete! Patience is key, as many users have experienced long installation times.

Generally, the more data, such as photos, apps, videos, and media, on your iPhone, the longer the iOS 18 beta installation will take.

iOS 18 Beta Running Slowly or Causing Your iPhone to Overheat

When you first install iOS 18 beta, your iPhone might run slower due to background tasks performing maintenance, indexing the device, and updating for iOS 18.

Sometimes, an iPhone running iOS 18 beta might feel hot or warm. This is often due to the same reason the iPhone runs slowly; extensive use of the processor for background tasks and maintenance.

Leave your iPhone plugged in overnight, and performance should return to normal the next day.

Some iPhone users, especially those with older models like the iPhone 11 and iPhone 12, have noticed that iOS 18 runs very slowly. Keep in mind this is a beta version, and performance is expected to improve with subsequent updates.

If performance is a concern for you, it's best to avoid installing beta system software.
