iPhone lagging after iOS 18 Update

After upgrading I am facing lagging issue while typing text. Some time typed lot of letter but they don’t appear and comes after some second.

i have 45 GB of free space

background app refresh is enabled for few important app.

not sure what’s problem. Hope Apple will take care this in upcoming upgrade.

it’s should not happen iPhone 12 and later phones.

If it wasn’t for my son I wouldn’t be dealing with another broken apple update. Oh dad you’re being ridiculous apple isn’t Microsoft! YES IT IS.

proved him Wrong! Apple never disappoints always predictable updates breaks everything just like Microsoft

I’m on a XR and I almost got into it with my phone lbs it’s laggy at times and if u need to get warm all u gotta do is put this bad boy in your undergarments and boom your body temperature will rise again !!

I swear I feel like I have a ticking time bomb on my hands .. perhaps if it’s able to update on the older models .. maybe it should be optimized more or something to fit the standards of the older phones cuz man it’s annoying

Yeah, it is. After iOS 18, my iPhone 11 Pro is lagging more than usual. I’ve been using iPhones since iOS 9, and this is the worst release Apple has ever made, even worse than iOS 17. There’s no downgrade option either without erasing everything. In my opinion, Apple is now in a rat race, and I can’t trust their future updates and decisions without thinking twice. 👎🏾

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.

Hopefully another update comes to fix the “bugs”. I keep having issues with hitting certain commands like closing tabs in Safari, having to double click things for it to load, my swiping is lagging, and sensitivity doesn’t seem to be all the way there although I adjust it.

The same has been happening to my 14 Pro Max since the update. I’ll wish I didn’t update! There’s a lot of lagging, freezing, inability to end calls, texts are all over the place. Please fix this Apple!

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.

Same issue here doing iOS18. iPhone 15 Pro Max became really slow, glitchy, and UI refresh rate got slower, after doing the recent update 18.1 and enabled Apple Intelligence it is even worse performance, battery degrades significantly. It is 9:30am now and battery is at 33% with low power mode enabled, around 7am I left the house with 100% crazy !

I think that this may help with the lag issue.

Go to the haptic settings and change it to Fast.

Unfortunately this wont help the real issue. Thanks

OMG, my lovely 14 Pro. I’m never ever upgrading it! Thanks for sharing!

I was having the same issue for long time... After I turned off low power mode it became bit better.

I updated my phone to 18.1 Shute it down and reset and now it works beautifully

I updated my iPhone 15 pro max to iOS 18.1 and did a shutdown and reset it and now my iPhone is back to working beautifully again
