iPhone keyboard lagging after iOS 18 Update

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.

I just updated to iOS 18.2 and I dunno everything feels much better. In fact I turned auto correct back on and predictive text and it feels about the same as before.

the biggest surprise was how my iPad mini 5 felt after the update. That tends to be my test bench before I update my iPhone 12. I do a lot of studying and note taking on the mini with split screen. And I like having the notes app opened while I jot down some notes along the way. And it doesn’t lag so hard like it did before. Here’s hoping this is a sign things are getting better.

For me with an iPhone 12, since 18.2 the keyboard is gotta be 95% better,

but I just wanted to share what my current settings are, so that maybe other people can maybe replicate what I’m experiencing?

i got two dictionaries downloaded, the Apple dictionary and the new Oxford English

Auto capitalization, auto correction, predictive text, check spelling, smart grammar punctuation, character preview and the “.” Shortcut enabled. Everything else in that list Is disabled.

auto dictation is on below that. And emoji stickers enabled.

and so far I will say compared to how things felt before, it’s significantly less lagy. The lag before like was 3-5 letters behind for me. Right now it feels like maybe 1-2 at the most.

Oh thank you so much!!!!! Yea this resolved the issue for me!!!

at least one issue is sorted and the other issues where autocorrection is back.. lol

thanks for the advice! Yes had to disable both autocorrection and predictive txt

Yes, it worked initially, but after a few hours, the issues came back.

The issue has been resolved on iOS 18.1.

I disabled keyboard haptic years ago and regardless still have some lag going on. The only thing that sorta helped was disabling predictive text but that also disabled my emojis too

I have to press hard on each key to get response after ios 18 update

I think i have finally fixed my issue. I went to settings>accessibility>touch accommodations...i turned off touch accommodations. Now when i touch a key it responds!!!

Fresh after the update of iOS 18.2 on my iPhone 15 Pro Max, everything felt smooth. A few hours later everything is back as before. Again everything is very slow and sluggish.

Don’t know about your devices, but on my 16 Pro Max, after 18.2 update, one of the worst keyboard experiences is in the calculator! The app is now unusable.

Please explain this clean install process I would like to give it a go. Are you talking about an erase all files and settings, connecting to a pc, and downloading the firmware? 🤷🏻‍♂️

I’m mostly on my iPad Pro (iPadOS 18.2) and it’s lagging bad. Sometimes the emoji keyboard comes up blank. Same problem in my iPhone 13 Pro. I never had this issue until 18.2. On either device.

... like all the weird typos & other things the phone happily accepted and now keeps bugging me? Well, guess there's not much to be lost.
