Troubleshooting Laggy iPhone After Update

Majority of the post-update performance issues are software-related. Thus, performing some basic tweaks can usually get the device back up and performing fast and smoothly again. Highlighted below are some helpful workarounds that you can try to fix your iPhone 13 Pro Max that’s running slowly after an iOS update. Try these before opting for service:

1. Update iOS again if a newer bug fix version is available

Known iOS bugs that are causing slow performance problems on an iPhone are usually addressed by Apple immediately with a follow-up minor firmware update containing the required fix patch. If you haven’t already, download and install the latest firmware version (iOS 17.0.2) on your iPhone. These emergency updates contain security enhancements and patches to fix prior bugs and system flaws.

2. Force quit all apps and restart your iPhone

If you left some apps opened and running in the background during the update, there’s a good chance that any of these background apps became unresponsive and eventually slowed your iPhone down. This is when force quitting background apps and restarting iPhone come in handy.

Force quitting all running apps and restarting your iPhone can help deal with post-update lagging issues in a few ways:

  • Frees up memory. When you force quit an app, it closes all of its background processes and releases the memory that it was using. This can help to improve performance, especially if you have a lot of apps running at the same time.
  • Clears temporary files. Restarting your iPhone clears all of its temporary files, which can also help to improve performance.
  • Refreshes the operating system. When you restart your iPhone, the operating system is reloaded from scratch. This can help to fix any minor software glitches that may be causing lagging.

4. Uninstall or delete large, unused apps

Performance issues including lags or sluggishness may likewise be associated with storage problems. This is usually the case when your iPhone is already running low on storage.

The iOS 17 update file is apparently huge and therefore requires a lot of storage space. If your phone’s memory was already low prior to the update, there’s a good chance that it gotten worsen afterward. As a result, the device slows down. In this case, freeing up some storage space would be necessary. One way to do this is to uninstall or delete unused apps from your device.

Uninstalling or deleting large, unused apps can help deal with post-update iPhone lags in a few ways:

  • It frees up storage space. Large apps can take up a lot of storage space on your iPhone. When you uninstall or delete large, unused apps, you free up storage space that can be used by other apps and the operating system. This can improve the overall performance of your iPhone, including reducing lag.
  • It reduces the number of background processes. Some apps run in the background even when you are not actively using them. This can consume system resources and slow down your iPhone.

If the app you want to uninstall is a pre-installed app, you can’t delete it permanently. However, you can offload it to free up storage space. To offload a pre-installed app:

  1. Follow the steps above to get to the app’s settings page.
  2. Tap Offload App.
  3. Tap Offload App to confirm.

Offloaded apps will be removed from your Home screen, but their data will be stored on your device. To reinstall an offloaded app, tap and hold the app icon in the App Library and tap Download App.
