iPhone display lagging after iOS 18.4 update

After updating the phone to version 18.4 of the display, it worked perfectly as it should, 2 days passed and the display began to work terribly, to start using the phone you need to wait about two minutes to enter the main screen, what should I do in this case?

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.



Remember, the right question often leads to the solution!



Was/Is your device Jailbroken? If that's the situation, please be informed that attributing the issues to iOS updates may not be accurate.



iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.


Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.


Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

Clear the Caches:


Clear "System Data"

Clear the storage named "System Data" (formerly called "Other"). It basically contains unnecessary files such as caches that are used for system ease of use - all of which gather over time. Use my User Tip: How to Clear "System Data" in your iPhone’s Storage - User Tip. Caches would be being used for remembrance of application use.l.
