Many curious users have installed iOS 18 beta on their iPhone or iPadOS 18 beta on their iPad, but since the beta system software doesn't always run the smoothest, some may be interested in removing the beta from the device and downgrading the iOS 18 beta back to the stable version of iOS 17.

Whether you're experiencing specific issues with iOS 18 beta, such as fast battery consumption, overheating of iPhone, app incompatibility, bugs, performance degradation, or anything else, you can downgrade with some effort and return to the stable iOS 17 version.

Let's take a step-by-step look at how to downgrade iOS 18 beta and return to iOS 17 on iPhone. This guide also applies to downgrading iPadOS 18 beta to iPadOS 17 on iPad.

Important Note: iOS 18 backup is incompatible with iOS 17

The iOS 18 beta downgrade method we will introduce, including all your personal data, depends on iOS 17 backups to your computer (Finder or iTunes) before installing iOS 18 beta.

If you did not back up your computer before installing the beta version, your downgrade option will require setting the device to a new device. This is because iOS backups do not support backward compatibility. Basically, this means that if you don't have an iOS 17 backup before installing the iOS 18 beta, you can't restore your data to iOS 17.

Even if you don't have an iOS 17 backup, you can still downgrade your device from iOS 18 beta, but it will be set as a new device without your data.

This is also one of the reasons why it is very important to back up your iPhone or iPad before installing any beta system software.

How to downgrade iOS 18 beta version back to iOS 17

The easiest way to downgrade back to iOS 17 from iOS 18 beta is to put your iPhone (or iPad) in recovery mode and then start device recovery. After iPhone or iPad recovery, you can restore your backup and retrieve all data. If you do not have a backup that is compatible with iOS 17, the device will have to be set as a new device. If you do not want to erase your device, please do not continue.

1. Connect your iPhone or iPad to your Mac or PC using a USB cable
2. Open Finder on Mac, or Apple Devices/iTunes on Windows PC
3. Now that the iPhone or iPad is connected to the computer, put it in recovery mode, press the following button sequence: Press and release the volume increase key, press and release the volume decrease key, and then hold the power/lock key until you enter recovery mode (the recovery dialog box will pop up on the computer)
4. Now select "Recover" to restore your iPhone or iPad to the latest stable iOS 17 version
5. Allow recovery process to be completed on iPhone or iPad
6. iPhone or iPad will eventually restart to a brand new installation of iOS 17 (or iPadOS 17), you can do the typical setup process, you will have the opportunity to restore backups from your computer to retrieve all your data, or set up your device as a new one

If you restore your iPhone or iPad from a backup made by iOS 17, you will soon be using your device again in iOS 17, and all data is successfully downgraded from iOS 18 beta.

If you haven't restored your iPhone or iPad from the backup, you'll run a new iOS 17 installation without data.

I only have an iCloud backup of iOS 18 beta, can I still downgrade to iOS 17?

No, unless you are willing to lose data, because the iOS 18 beta iCloud backup is not compatible with iOS 17.

Your best bet is to keep staying on iOS 18 beta and continue installing the iOS 18 beta update on your device.

The final version of iOS 18 will be more stable and reliable when it is released in the fall, and subsequent betas will usually be more reliable.
