Apple’s iOS 18 and iPadOS 18 have been out since September, but more features are coming, and you can test them after installing a beta build for iOS 18.3 or iPadOS 18.3.

Apple Intelligence debuted on iOS and iPadOS 18.1 and expanded on iOS and iPadOS 18.2, but iOS and iPadOS 18.3 improve upon them even more. But there are also new features and changes beyond Apple Intelligence you’ll want to try out.

The iOS 18 and iPadOS 18 betas were first available to registered developers on June 10 and to Apple Beta Software Program users on July 15. While stable iOS 18 and iPadOS 18 versions were released to everyone on Sept. 16, Apple continues beta testing 18.x versions. The iOS 18.1 and iPadOS 18.1 updates were released on Oct. 28. The iOS 18.2 and iPadOS 18.2 updates were released on Dec. 11.

The most recent beta build for the 18.3 developer beta for iPhone and iPad is 22D5034e, which started rolling out on December 16. The public beta should follow soon.

Anyone with an iPhone and Apple account can sign up and install the iOS or iPadOS 18 beta. If a public beta is not available, you can still create a free Apple Developer account to skip the wait.

Backing Up Before You Continue

Beta software isn’t perfect, so it’s always a good idea to back up your iOS or iPadOS software before installing a beta build. That way, you can downgrade to a public build if needed. Backups on iCloud are encrypted and can be up to 12 TB (or 14 TB with Apple One Premier). Backups on a computer aren’t encrypted by default and are only limited by the remaining space on your local drive.

To create a backup on iCloud, connect your iPhone or iPad to Wi-Fi, go to Settings » [Name] » iCloud » iCloud Backup » Back Up Now. If you choose to back up with your Mac, you should archive the backup so that future beta backups won’t overwrite it. To back up with your Mac:

1. Connect your iPhone or iPad and Mac with a compatible cable.
2. Trust your computer if asked.
3. Select your iPhone or iPad from Finder’s sidebar on your Mac.
4. Choose the “General” tab if not already open.
5. Check “Back up all of the data on your iPhone [or iPad] to this Mac” in the Backups section.
6. Check “Encrypt local backup” to protect it with a password. (This is optional.)
7. Click “Back Up Now.”
8. Click “Manage Backups” after Finder finishes backing up your iPhone or iPad.
9. Right-click or Control-click on the backup you want to archive.
10. Choose “Archive” from the contextual menu.
11. A date should appear in the backup’s name, indicating it is now protected from overwriting.

Both options will omit:

• Apple Mail data.
• Face ID or Touch ID settings.
• Data already synced and stored in iCloud, such as Contacts, Calendars, Notes, iCloud Music Library, iCloud Photos, iMessages, and text (SMS) and multimedia (MMS) messages.
• Apple Pay information and settings.
• Content from iTunes and App Store.

A backup on your Mac will also omit content synced from your computer, such as imported MP3s or CDs, videos, books, and photos. To back up Activity, Health, and Keychain data on your Mac, you’ll need to select the encrypted backup option.

Updating iOS 18 / iPadOS 18 Beta Software

If you already have an iOS 18 beta or iPadOS 18 beta installed on your device or have joined a beta before, you can simply go to Settings » General » Software Update to install new versions. When new versions are ready to be installed, you’ll see them directly on the Software Update page. If you’re not seeing any updates, ensure you’re signed into the correct account as follows:

If you already have the iOS 18 or iPadOS 18 beta installed or have joined a beta before, just head to Settings » General » Software Update to install new versions. Updates will appear here when available. If you don’t see any updates, check your account by following these steps:

1. Go to Settings » General » Software Update » Beta Updates.
2. Ensure the correct Apple Account (from the Apple Beta Software Program or Developer Program) is listed at the bottom. If not, tap it, select “Use a different Apple Account,” and sign in. Changing your Apple Account here won’t affect other Apple services on the device.
3. Make sure iOS 18 Beta or iPadOS 18 Beta is selected.
4. Go back to the Software Update screen to check if the beta is ready to install.
5. Install the beta update like any regular software update.

If a newer iOS 18 or iPadOS 18 beta is available before the stable release of the previous iOS 18 or iPadOS 18 beta, it will appear under “Also Available” on the Software Update page. Tap the beta in that section, then install the beta update like any regular software update.

Installing iOS 18 / iPadOS 18 Public Beta Software

These instructions assume you are already running iOS 16.4 or later or iPadOS 16.4 or later on the target iPhone or iPad.

1. Enroll your Apple Account in the Apple Beta Software Program if it hasn’t already been enrolled from previous beta installations. Visit beta.apple.com, then hit “Sign Up” or “Sign In.”
2. Log in with your Apple Account, read the agreement, and tap “Agree.”

3. Go to Settings » General » Software Update » Beta Updates.

6. Go back to the Software Update screen to check if the beta is ready to install.
7. Install the beta update like any regular software update.

As a beta tester, you can provide feedback to Apple about any software issues you experience, which will help get the iOS 18 and iPadOS 18 stable updates as bug-free as possible. You can give feedback via the Feedback Assistant app on your iPhone. The app is usually hidden on stable iOS and iPadOS software but visible when on a beta. If you want to attach a sysdiagnose report with your feedback, to help Apple determine what led up to the issue, use the volume buttons shortcut.

Using a Restore Image to Install an iOS 18 / iPadOS 18 Beta

The iOS 18 beta is available on the following iPhone models, which are the same as those that work with iOS 17. So, if your iPhone runs iOS 17, it can run iOS 18.
