Restart Your iPhone

The first step any time you notice performance issues or lag on your iPhone is to restart it. A simple restart can clear out memory leaks, flush caches, and remedy many problems caused by the iOS 17 upgrade.

To restart an iPhone 8 or later:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side button until you see the Apple logo appear.

For iPhone 7 or earlier:

  1. Press and hold the Sleep/Wake button until you see the slider.
  2. Drag the slider to turn off your iPhone.
  3. After 30 seconds, press and hold the Sleep/Wake button to turn your iPhone back on.

Restarting gives your iPhone a fresh start, closing all open apps and clearing temporary files that may be slowing things down. This quick fix may be all you need to get your iPhone back up to speed after iOS 17.

Update Apps to Latest Versions

Outdated apps are a common source of lag and crashes after an iOS update. Developers need to optimize their apps for the latest iOS version through updates.

Go to the App Store on your iPhone and tap your profile icon in the top-right. Then select “Update All” to automatically update all your apps to the latest versions. Updating your apps ensures compatibility with iOS 17 and resolves any performance issues.

Pay special attention to updating frequently used apps like social media, messaging, email, and gaming apps. You can also go through app by app and tap “Update” next to each one needing an update. Update all apps for the smoothest iOS 17 experience.

Reduce Animations

The animations and motion effects in iOS help create a fluid, engaging experience. However, too many animations running at once can overwork your iPhone’s processor and graphics capabilities leading to choppy performance after an iOS update.

You can speed up your iPhone by reducing certain animations in the Accessibility settings:

  1. Open the Settings app and tap Accessibility.
  2. Scroll down and select Motion.
  3. Turn off the following:
    1. Reduce Motion
    1. Auto-Play Video Previews

Disabling these animations gives your iPhone less work to do for a snappier feel. Try toggling them off and see if it helps improve overall responsiveness on iOS 17.

Turn Off Background App Refresh

Background App Refresh is a useful iOS feature that keeps apps updated with the latest data even when you aren’t using them. However, it can also tax your iPhone’s CPU and memory. If you have many apps refreshing in the background, it can cause lag when trying to use your iPhone normally.

To see if disabling Background App Refresh helps:

  1. Go to Settings > General.
  2. Scroll down and tap Background App Refresh.
  3. Switch Background App Refresh to Off.

Turning this feature off prevents apps from running background tasks and using resources while you aren’t actively using the app. Your iPhone has more power for the apps you currently have open.

Check for Software Update

Apple will often release incremental iOS updates after a major version like iOS 17 to address bugs and performance issues. Check to see if a new software update is available containing fixes for any lag you’re experiencing:

  1. Open the Settings app.
  2. Tap General > Software Update.

If an update is available, install it and see if your iPhone’s performance improves afterward. Keeping your iPhone updated with the latest software ensures you have all the latest optimizations.

Reset All Settings

Resetting your iPhone to factory default settings can fix performance issues caused by problematic settings that don’t jive with iOS 17. Note that resetting settings will not delete any data or content, just settings.

To reset all settings:

  1. Go to Settings > General > Reset.
  2. Tap Reset All Settings.
  3. Enter your passcode if prompted.
  4. Tap Reset All Settings again to confirm.

Your iPhone will reboot and you’ll have to reconfigure any customized settings. While inconvenient, the fresh slate can eliminate issues stemming from settings conflicts.

Clear Browser Cache and Data

Web browsers like Safari cache data to quickly load websites you frequently visit. Over time, the cache can build up and start to impact performance.

After a major iOS update, clearing the browser cache gives Safari a fresh start, which could help if you notice lag when using Safari on iOS 17.

To clear the Safari cache:

  1. Open Settings and tap Safari.
  2. Choose Clear History and Website Data.

This wipes the cache, cookies, and history. Any lag issues related to browser data will be addressed. You’ll have to re-enter passwords and login to sites again after cleaning the browser data.

Delete and Reinstall Problematic Apps

An app that is not playing nice with iOS 17 could be the culprit behind your iPhone’s lag. If you notice an app crashing frequently or slowing down your iPhone, try deleting and reinstalling it:

  1. Delete the problematic app.
  2. Restart your iPhone.
  3. Reinstall the latest version of the app from the App Store.

This gives you a clean slate with no corrupt app data that could be conflicting with iOS 17. A fresh install of the app has a good chance of fixing any compatibility issues.

Disable Accessibility Shortcuts

The Accessibility Shortcuts feature can be convenient for quickly enabling and disabling certain settings. However, some shortcuts like Reduce Transparency, Smart Invert, and others can inadvertently slow down your iPhone when toggled on accidentally.

Turning off accessibility shortcuts prevents this:

  1. Go to Settings > Accessibility.
  2. Tap Accessibility Shortcut at the top.
  3. Turn off all shortcuts you don’t use regularly.

Fewer shortcuts means less chance of enabling a performance-hindering setting that drags down your iPhone. Disable what you don’t need.

Check Battery Health

Battery degradation over time can reduce performance. As battery capacity deteriorates, the iPhone may throttle CPU and GPU speeds to compensate. This can cause lagging, especially after demanding updates like iOS 17.

Check your battery health in Settings > Battery > Battery Health. If your Maximum Capacity reads lower than 90%, the battery may be failing, limiting full performance.

Consider replacing the battery to restore peak performance if it is worn out. iOS 17 runs best on an iPhone with maximum battery capacity.

Update iPhone Software Using Finder/iTunes

Installing iOS updates wirelessly over-the-air can sometimes create software bugs or issues. For a clean install, try updating your iPhone using a wired connection to your computer.

For Windows:

  1. Download and install the latest iTunes version.
  2. Connect your iPhone to the computer via USB.
  3. Open iTunes. It should detect your connected iPhone.
  4. Click on your iPhone icon, then click Summary.
  5. Click Check for Update in iTunes.
  6. Download and install any iOS updates shown.

For Mac:

  1. Open Finder on your Mac.
  2. Connect your iPhone via USB.
  3. Click on your connected iPhone under Locations in Finder.
  4. Click General > Check for Updates.
  5. Download and install any available iOS updates shown.

Updating through iTunes or Finder downloads a fresh, clean copy of the iOS firmware file and installs it on your iPhone for a trouble-free update process.

Restore iPhone Using Recovery Mode

If all else fails, you can wipe your iPhone completely and restore from an iOS backup. This should eliminate any corrupted files or settings that may be slowing down your device after the iOS 17 upgrade.

Note: This will erase your iPhone data so make sure you have a recent iCloud or iTunes backup!

To restore via recovery mode:

  1. Connect your iPhone to your computer via USB.
  2. Put your iPhone in recovery mode:
    1. iPhone 8 or later: Press and release Volume Up. Press and release Volume Down. Then press and hold the Side button until you see the recovery mode screen.
    1. iPhone 7 and earlier: Press and hold both the Home and Top buttons until you see the recovery mode screen.
  3. In iTunes or Finder, you will be prompted to Restore your iPhone. Click Restore to proceed.
  4. Once the restore completes, set up your iPhone as new or restore an iCloud/iTunes backup during setup.

Restoring your iPhone gives you a fresh iOS install free of any bugs that may be slowing down performance after the iOS 17 upgrade.

Contact Apple Support or Take to Apple Store

If you continue experiencing severe lag or sluggish performance after trying the above solutions, you may need to contact Apple for support:

  • Apple Support: Book a session with Apple Support advisors who can run diagnostics and troubleshoot further.
  • Genius Bar: Make an appointment at an Apple Store Genius Bar where advisors can diagnose hardware-related performance issues.
