After today’s update, I’m facing immense lagging issue with the UI, while playing games ( graphics as Average) and typing pauses. System had utilised only 50% storage. What’s the suggested solutions?

iPhone 14 Plus, iOS 18
THIS WORKED PERFECTLY!!
I read through this entire discussion post and this was the first solution I tried and it was easy and it worked.
The search and Siri settings pages have been separated in iOS18, so I just toggled everything off from both settings pages. Then, I powered off my phone and let it rest for a couple minutes. Powered back on, turned all the settings back on, and ALL ISSUES have gone away…
Note: your phone might lag a little bit while starting up again, make sure to close all tabs and let the software boot up
EDIT: I realized the reply function doesn’t really work so the original post I was quoting does not show. I mostly outlined the process of fixing the iOS18 lag issues, but if this explanation isn’t clear just find an earlier post of someone talking about search and Siri steps.
I think that this may help with the lag issue.
Go to the haptic settings and change it to Fast.
Look up how to reset your keyboard dictionary, I didn’t think it would work but for some reason it did!
If u r facing lagging issues after iOS 18 update, then do ‘reset all settings’
issues will be cleared
The iPhone 16 is native to the new iOS 18, it is literally what the phone was built for, but all the other lineups (as you said, iPhone 14 pro) are not. You need to wait for patches, iOS 18.1 etc... for your older iPhone to actually work without lags, bugs, battery drops, frame drops etc... That's why they offer iOS 17.7 alongside with iOS 18. You don't need to buy a new phone, you just need to wait.
Apple keeps removing my posts- please Apple do not keep removing my posts to hide the extent of this issue!
apple this is my fourth post on this please stop deleting my posts
Resetting the dictionary seemed to help somewhat.
Anyone experiencing the ongoing device setup bug? Its under settings>battery>ongoing device setup It usually only last a few days then goes away but lately it popped up again. Ive been reading from others this has happened for them too. No clue why. Good thing I turn off my phone every night when I go to bed.
Any article that starts by suggesting you force-quit all your apps is suspect; they have no idea how iOS works. Those apps are not consuming resources and you're actually working against optimizations in iOS.
You should only force-quit an app like that if it's misbehaving.
i’ve updated the iOS to 18.0 on my iPhone 14 Plus, I’ve been seeing too many glitches where I log onto my phone to the main screen and switch over the pages to get to an app and it goes blue. Another issue my contact in messages show phone numbers rather than the contact name until I open the direct message and it shows the name instead of their number.
I remember years ago I was told never to download the first IOS to wait for the .1 or .2 to then update because .0 will always have glitches. Apparently it is true so far. I have even tried to turn off my phone and restart it but it still does the same thing.
same!! Also have a 15 pro max not even a year old and updated to iOS 18 last night. After my phone has been super laggy/glitchy. Examples like loading pages/sites on safari is taking forever, the widget for Apple News isn’t even showing anything and says “Apple News is offline” but if I click on it Apple News opens up like usual and I used Apple Maps for directions today for the 1st time (hooked up to my car) after the update and it took soooo long for it to load the directions and when I decided to take a different route than what Apple Maps wanted me too it freaked out and went into the load screen for a couple min trying to give me new directions. That has never happened before where it’s taken that long to find new directions, and I even had full service, before even when I’ve barely had service it found new directions pretty much instantly . It just seems like everything is so much slower now than it used to be and it’s not like my storage is close to being full or anything, I currently have 142 GB out of 256.
About a month later: 18.1 did not bring relief but the system is *slightly* less laggy. Persisting problems:
CAMERA continues to hang up and is the most frequent cause for initiating restart. The camera might appear to snap a shot but none is saved. (40GB storage space on the phone with 2T iCloud backup & storage optimization on)
Inability to MULTITASK: e.g. listening to music (an album saved on the phone so theoretically required less resources) and turning on the camera instantly freezes the system.
Issues with CALLS: regular but mostly WhatsApp - if receiving a call after having used other apps, like reading mags, chances are the call won’t come in smoothly ( inability to hear or be heard).
ISSUES I AM SEEING LESS OFF: Fewer instances of sticky keys, seem to be able to type normally. Dictation ok.
This is May 2025 and the issue is still overwhelming on older iPhones. Rendering the device practically unusable. Basically it overheats a lot. And too much of a battery drain, lags too much. Touch input is also lethargic.
I have an iPhone SE20 in good condition. Ever since updating to iOS 18, the performance has been abysmal. Things like starting safari where I have no active tabs, and watching, whilst over 20 seconds are needed for it to load the thumbnails and icons of the bookmarks.
Tapping on a notification causes very noticeable pause and lag for the entire UI whilst the phone tries to get to what the notification was linking to.
It's appalling just how poorly iOS 18 is performing. I have disable all Apple Intelligence features that are available (or that I can reach) to 1, not have them interfering, and 2, in an attempt to keep the phone doing as little as possible.
Even after 18.1…. That’s a surprise. I wonder if a full reset would solve the issues. Did Apple give this enough testing? 😳😲
I updated my phone to iOS 18.1 and did a shutdown and recovery and it fixed my phone and now it’s back to good performance
