iPhone keyboard lagging after iOS 18 Update

Yes! This is literally me. I’d been thinking it was my phone because of how old it is compared to the newest ones (11) but My friend who has the 14 told me last night that she updated to iOS 18 and her keyboard started glitching like crazy when she’d never had problems with it before so it wasn’t just my phone. Which is what made me come look into it

This is exactly what fixed it for me. I had tried resetting the keyboard dictionary, which didnt work. But turning off “predictive text”, “auto-correction”, and “show math results” completely removed the keyboard lag I have been experiencing since updating. If youre experiencing this, i suggest turning these features off if you can deal with auto correct not being on.

Settings —> general —> keyboard

iOS 18.1.1 issue is still happening even in the passcode sign on screen. I have reset the keyboard dictionary and disabled multiple options on the keyboard and I can still type 2 to 3 sentences before the on screen keyboard catches up. The lag is horrible I thought by installing Google board that it would help, but the problem still exist, even in third-party applications. I uninstalled the Google board and I am still having issues with the regular iOS keyboard the other issue is it's not suggesting emojis either when I have the options enabled and the emoji keyboard enabled. I have tried reset all settings and the problem still exist.

Apparently Apple do get data about this sort of problems but either don't care or they don't know what really causes it.

If you look into analytic data on your iPhone, you can see that the phone sends regular reports back to Apple about any bug. In my case for example, only in the past 4 days the phone reported multiple problems with the keyboard. I used chat gpt to decode the file, as it is easier to read this way.

i also experienced random heating lately while scrolling on websites on Safari and doing light tasks. Those heating issues also appear in the analytics but somehow Apple manages to screw something back with every update lately.

Everyone you need to do a clean install after a big update.!I did everything and finally I remember when I went from 16 to 17 it’s was a similar issue apple isn’t doong anything because Ionce you do a clean install there is zero issue. I did it to my whole family’s devices and zero issue keyboard is so fast I can’t even type fast enough to have any lag. Your welcome everyone do a clean install and boom restore from iCloud back and zero issue I have a brand new iPhone again thank the lord and I didn’t have to download Microsoft keyboard!!! Apple you have restored my faith and do not download temu on your phone that slows the phone down as well. Merry Christmas

I updated to 18.2.1, wasn’t fixed. For me it’s emoji keyboard. Tap on it and eventually it doesn’t load (it’s blank) Have to back out to the Querty then back to the emoji. Rebooting fixes it for a bit then it happens all over again.

Good advice! I disabled the predictive text and seems like the lag is gone. Writing is a little bit hard now, but it’s kind ok…

Thank you so much!

I had 5-6 dictionaries downloaded, did as you said and I think it might help. Will need to use some more time and come back here to give some reviews..

yep most definitely this has been fixed since the new update of 18.1

Nope it still doesn't work proper. If I delete one of the languages and leave only English or my main language it's all right, but if I have both on it's unbearable

**** just did it and lag is worse and lost my learned data Jesus people are the worst

Lol, why would you do that.

delete data is the last thing you want to do.

its a bug, just wait for a proper fix from apple

I think it’s an apple intelligence thing because my issue has resolved itself. I didn’t even noticed

yesterday I've even reset my iPhone, but again, without success. Is someone experiencing the same issue even in iOS 18? And have you managed to fix this? Thank you.
