Fixing a sluggish iPhone that keeps lagging or freezing after iOS 13

In this post, we will try to look into all possibilities and rule them all out one after another until we can determine the reason as to why your iPhone has become laggy and sluggish after the iOS 13.3 update. With that being said, here’s what you should do: 

First solution: Try doing the Forced Restart 

It sometimes happens that after an update, some files or caches gets corrupted and it may need more than one reboot sequence before a device can run properly again. As an owner, you should be able to tell or compare the performance of your iPhone before and after the update. If it was working properly prior to the iOS 13 update, then the problem is pretty minor and doing the forced restart may be able to fix the issue. Therefore, the first thing that you have to do if your iPhone has become laggy is the forced restart.

How to force restart a laggy iPhone

  1. Quickly press and release the Volume Up button, and then quickly press and release the Volume Down button. 
  2. The moment you release the volume down button, press and hold the Side or Power key until the Apple logo shows on the screen. 

When the reboot is finished, try to see if your iPhone is still laggy or slow. If it is, then move on to the next solution. 

Second solution: Try closing all apps running in the background

As we know, apps are left running in the background even after you use them. Depending on how you look at it, that’s actually a good thing because you don’t have to wait for several seconds to re-use the apps that might be important to you. However, if there are already so many applications that run in the background, that could also affect your device’s performance and that might be the case here. So to rule out this possibility, it’s best to close those apps while you’re troubleshooting your iPhone. 

How to close background apps on an iPhone

  1. Swipe up from the bottom of the screen and stop at the middle to view the app previews. 
  2. Now swipe up on every preview to force close all the apps. 

After closing all applications that are running in the background, try to observe your iPhone to see if it’s still laggy. If the problem remained, try the next solution. 

Third solution: Reset all the Settings on your device

Since this kind of problem started after an iOS update, it’s possible that some settings on your iPhone have been messed up and that might be the reason why it has become so slow and laggy. Fortunately, if that’s the case with you iPhone, there’s a procedure you can do to fix it and that’s to reset all settings. If you do this procedure, only the settings you made will be deleted and none of your files, data or apps will be erased. 

How to Reset All Settings on iPhone

  1. From the Home screen, tap Settings. 
  2. Find and tap General. 
  3. Scroll down to the bottom of the screen, and then touch Reset. 
  4. Touch Reset All Settings. 
  5. If prompted, enter your security lock. 
  6. Tap Reset All Settings at the bottom of the screen, and then tap Reset All Settings again to confirm. 

Your iPhone will reboot after this, once it has finished rebooting, try to use the phone as you normally would to see if it’s still sluggish, slow or laggy. When it comes to problems like this, more often than not, this procedure is more than enough to fix it. However, if your iPhone is still laggy and sluggish after this procedure, then try the next one. 

Fourth solution: Backup your files and reset your device

When it comes to performance issues, a reset can always fix them provided that the iPhone doesn’t have any signs of physical or liquid damage. That’s what you have to do now but prior to that, make sure to create a copy of your important files and data because they will be deleted from your iPhone and you may not be able to retrieve them after the reset. After the backup, follow the instructions below on how to reset your iPhone.

  7. Tap Erase iPhone at the bottom of the screen.  
  8. Tap Erase iPhone again to proceed with the reset.

Restoring your iPhone would always fix any firmware or software issues including performance problems. However, it may not be as easy as the rest of the procedures you have done. Some may find it very complicated so if you’re one of those users, it’s better to just let the Apple tech handle the problem for, although you may have to set up an appointment at the Genius Bar first.
