As we move past the release of iOS 17, we’re hearing about a variety of performance issues affecting iPhone users.

While many iPhone users are having a great experience with Apple’s new operating system, others are complaining about bugs and performance issues.

The current list of iOS 17 performance issues includes UI slowdown, freezes, freezes, and random restarts. These are very common, especially on older iPhone models. However, newer iPhone models are not immune to performance issues.

Performance issues can be difficult to resolve. And while you may be able to fix them yourself, others may need a fix from Apple in a software update. In some cases, you may need to contact Apple Support or take your iPhone to an Apple Store.

If you can’t wait for a new version of iOS 17 and/or don’t have time to contact Apple Support, we have some solutions that can help resolve performance issues in iOS 17.

Restart your phone

If you notice a UI lag or other performance issue after installing iOS 17, you can try restarting your iPhone.

Turn it off, leave it off for a minute and then turn it back on. This has solved many performance issues for us in the past.

Update your iPhone

Apple will occasionally push new iOS 17 software to your iPhone. Point updates (xxx) typically focus on bug fixes, while milestone upgrades (xx) typically deliver a mix of new improvements.

The company may not mention performance improvements in the change log of an iOS 17 update, but new software always has the potential to improve (or in some cases, harm) the overall performance of your iPhone.

To learn more about the latest version of iOS 17, check out our guide.

Update your apps

If you haven’t already done so, make sure you update your applications to the latest version.

App developers are rolling out support updates for iOS 17 and can help stabilize iOS 17 performance on your iPhone.

Before you install the latest version of an app, go to the App Store and read reviews from other iOS 17 users. If the reviews are mostly good, download the latest version.

Clean up your iPhone’s storage

If you’ve had your iPhone for a while, you might have a lot of junk taking up space on the internal storage.

Deleting unnecessary files can help speed up your iPhone. This is especially true if you’re running out of storage space.

To start with, you need to check how much space is free on your iPhone. Here’s how to do that:

  • Go to Settings
  • Tap General
  • Tap iPhone Storage

Apple makes some recommendations based on your usage of your iPhone’s storage space, but you can also just go through each section manually and delete files you no longer need.

Stop using app refresh in the background

Background App Refresh refreshes apps in the background to show you the latest data when you open them. It also makes your phone work in the background.

If you don’t need your iPhone for this, you may want to disable the feature. Here’s how to do that:

  • Go to the Settings app
  • Tap General
  • Tap Background App Refresh
  • At the top of this screen, tap Background App Refresh and turn it off

If you want to keep it enabled for some apps, leave it enabled, then go through your list of apps and manually disable it for apps you don’t use.

Reset all settings

If you’re still not getting the performance you want from your iPhone, try resetting your device’s settings. Here’s how to do that:

  • Go to Settings
  • Tap General
  • Tap Reset Transfer or Reset iPhone
  • Tap Reset
  • Tap Reset all settings
  • Enter your passcode if you have one enabled

This will reset your iPhone’s settings to factory defaults.


If you can’t find a solution to your problem and/or don’t want to wait for the next version of iOS 17, you can try downgrading back to the previous version of iOS. Your downgrade options change over time and sometimes downgrading is not available.

Check out our walkthrough to learn more about the iOS downgrade process.

To recover

If you can’t find a solution to your problem and want to avoid taking your iPhone to a store, you may be able to restore your device. This should only be used as a last resort.

You can do this via Finder, iTunes, or iCloud.

If security is important to you, consider installing Apple’s iOS 17 update right away.

iOS 17 brings new security patches to the iPhone. If you’re interested in the exact nature of these improvements, you can read about them on Apple’s security website.

If you skipped older versions of iOS, like iOS 16.6.1, you’ll also receive the security patches from those updates with your iOS 17 update.

In addition to these patches, iOS 17 brings some additional privacy and security improvements, including improvements to communications security outside of messaging.

It now includes content sent by AirDrop, contact posters in the Phone app, FaceTime, and the system-wide photo picker. You now have an option to blur sensitive photos and videos before you choose to view them.

There is also an extended Lockdown mode that helps protect you from cyber attacks.

Apple has also improved sharing permissions and you now have more control over what you share with the apps on your device.
