Fix iPhone Lagging and Freezing After iOS 17 Update in 10 Easy Ways

iOS updates bring in new features, enhance the security of the iPhone, and also optimize it to perform better. Sadly, numerous users have reported that ever since they updated to iOS 17, their iPhones have been lagging. Moreover, there are constant frame drops while scrolling, keyboard freezing when typing and even the browsing experience on Safari has deteriorated. If you’re facing similar problems, we’ve put together this guide to help you fix iPhone lagging after the iOS 17 update. 

How To Fix iPhone Lagging and Freezing After iOS 17 Update
1. Change Keyboard Settings To Fix iPhone Lagging After iOS 17 Update
With iOS 17, Apple updated the Auto-Correction feature with a transformer language model which also improves the Predictive Text feature. The keyboard has inline predictive text recommendations too. While this is a step in the right direction, it consumes a huge chunk of resources, especially if you have an older iPhone. 

Therefore, we suggest disabling the Auto-Correction and Predictive Text feature on your iPhone as it might help fix your iPhone lagging. Especially because other users have reported that doing so helps resolve the issue.

Time needed: 2 minutes
Steps to disable Auto-Correction and Predictive Text in Keyboard settings.
Open Settings on your iPhone and head to General. 
Tap the Keyboard option. 
Disable the Auto-Correction toggle. 
Next, disable the Predictive Text toggle.  

2. Remove Dictionary and Add It Back
The Dictionary feature helps you “Look Up” the meaning of words on your iPhone. You can add dictionaries of several different languages. But for some reason, these dictionaries might be the reason your iPhone is lagging. 

Yes, it does not make a lot of sense, but a user on the Apple Discussion Community have reported that removing all the dictionaries and then adding back only the ones you use helps fix iPhone lagging issues. Therefore, we suggest you do the same. 

Open Settings on your iPhone and head to General. 
Tap the Dictionary option. 
Unselect all the options on the Dictionary screen.

Restart your iPhone. If you’re unaware of the steps to do so, ask Siri to restart your iPhone. 
After your iPhone restarts, head back to Settings > General > Dictionary. 
Now, tap on the Dictionaries that you need to re-download them.

3. Disable Siri Contact Suggestions
Are you unable to search contacts or do the contacts take a long time to load in the Phone/Contacts app on your iPhone? Does your iPhone lag a lot when using the Phone app? In this case, we suggest that you disable Siri & Search and Show Contact Suggestions from the Contacts Settings. 

Why? It seems that certain software bugs in this feature are preventing the iPhone from functioning smoothly. And, disabling these features helped fix lagging issues in the Phone app on iPhone. 

Open Settings on your iPhone and head to the Contacts option.
Tap the Siri & Search option. 
On the next screen, disable the Learn from this App toggle. 
Disable the Show Contact Suggestions toggle too. 

4. Clear Safari History and Data
If Safari is lagging, freezing, or crashing on your iPhone running on iOS 17, the first thing you must do is to clear Safari’s History and Website Data. Safari might be lagging due to stored-up data instead of bugs in iOS 17. 

Open Settings on your iPhone and navigate to Safari.
Scroll down and tap the Clear History and Website Data button. 
Select the All History option from the Clear Timeframe menu. 
You can also enable the Close All Tabs toggle. It won’t delete any tabs that are in a Tab Group. 
Finally, tap the Clear History button. 
Scroll to the bottom of the page and tap the Advanced button. 
Tap the Website Data button. 
On the Website Data page, tap the Remove All Website Data button. 
Tap the Remove Now button to confirm your selection. 

If the aforementioned steps don’t fix the freezing issues on your iPhone, please refer to our detailed guide on how to fix Safari Freezing on your iPhone. 

5. Clear Background Apps To Fix iPhone Lagging After iOS 17 Update
Apps running in the background can also be the reason why your iPhone is lagging. Please clear all the background apps and it might free up the RAM and fix lagging issues. 

For iPhone with Face ID: Swipe up and hold on to the Home Screen. 
For iPhone with Touch ID: Double tap the Home Button.
Swipe up on all the apps in the Recent Apps tray. 

6. Force Restart iPhone To Fix Lagging

Steps to Force Restart iPhone (iPhone 8, iPhone SE 2nd Gen and above)

7. Update All Apps To Fix iPhone Lagging After iOS 17 Update
Does your iPhone lag only in some apps but not the others? Well, have you considered that the app might be outdated which is the reason it is lagging and iOS 17 is not to blame? Yes, it is possible which is why we suggest that you update all the apps to their latest versions immediately. 

Open the App Store on your iPhone.
Tap on your Profile at the top right corner. 
Scroll down to the Available Updates section and tap the Update All button. 

8. Check Storage Space
Most of us are aware that iPhones tend to lag when running extremely low on storage space. If you haven’t already, please check the free storage space on your iPhone. If it is low, we suggest uninstalling apps or unused media files to free up storage space as it might help fix the lag or stutters on your iPhone. 

Open Settings on your iPhone and head to the General option.
Tap the iPhone Storage option. 

The next screen will display the amount of occupied and total storage space on your iPhone. You can delete apps that you don’t use often to free up storage space on your iPhone. 
Tap on any app you want to delete.
Next, tap the Delete App button, and then tap the Delete App pop-up to confirm your selection. 

Also, in case your iPhone displays a “Recommendations” option, tap on it and follow the recommended actions to free up storage space. The quickest way to empty storage space is to use a maintenance tool. One of the most popular apps is the Intego Washing Machine because it fully declutters your iPhone and increases its health significantly.

9. Update to the Latest Version of iOS
There are several versions of iOS 17. And Apple keeps releasing updates periodically. There are chances that a certain build of iOS 17 is plagued with major bugs that are causing these lagging issues. We suggest updating to the latest version of iOS 17 as it will most likely fix these bugs especially if they are widespread. 

Open Settings on your iPhone and head to the General option.
Tap the Software Update option on the next screen. 
Here, tap the Install Now or Update Now button to update your iPhone to the latest iOS version.
Enter your device’s passcode to continue. 

10. Factory Reset iPhone
If none of the aforementioned methods help resolve the issue, the last option you’re left with is to factory reset your iPhone. Please refer to our guide on How to Factory Reset Your iPhone for detailed instructions. 

We hope this guide helps fix your iPhone lagging after the iOS 17 update. If you have any doubts, please let us know in the comments below.
