iPhone keyboard lagging after iOS 18 Update

Hello guys, I have an iPhone 13 Pro Max and I've been suffering for the famous keyboard lag since I've updated to iOS 17 one year ago. In my case the problem starts to occur when I enable 2 languages on my keyboard (for me, Italian and English). I hoped that with the iOS 18 update and the introduction of the bilingual keyboard this bug would finally be fixed but sadly, that was not the case. I've tried every possible troubleshooting known for this issue, 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.

Hello guys, I'm gonna share with you a little tip that might help you with this issue. If you go into Settings -> General -> Dictionary you will see the list of dictionaries enabled on your iPhone, in my case, 5 dictionaries were selected: Italian/English, 2 different English dictionaries, an Italian one and Apple Dictionary. I tried disabling the Italian/English one and one of the 2 English ones and the lag seems better on my device (not 100% gone but much better than before). I don't know if this will work also on your devices but you might give it a try, it doesn't seem to affect the keyboard prediction accuracy. I'll attach a screenshot of the settings page I'm talking about.

I was wondering about that. My iPhone 13 Pro has no problems nor my iPad Mini (which can’t run Ai) All my keyboard problems seem to be with my IPad Pro. Going to give this a shot.

Its really bizarre this many people are having rhis problem and apple has done nothing about it for years.

It doesn’t matter what app I’m using or how many times I have disabled haptic feedback, deleted the keyboard, shut off predictive text etc. Nothing works.

When you start typing it’s like starting a countdown. The more characters you type the worst it gets. For example right now it’s starting to slow down to the point that is almost unusable.

The only way I fix it is by copying the text, force quitting the app and then re-opening it. That restarts the “countdown” and gets me a few more answers until I repeat the process.

The only thing that I have not tried is getting a new battery. I know that sounds ridiculous but I have tried everything else and when I look up the condition of my battery it IS degraded……

I have ordered a new battery and I’m waiting for it to get here. In the meantime if you are reading this, open up your settings and click on the battery health. If your battery is degraded significantly and your keyboard is lagging can you let me know? Thanks!

I am on 18.4.1 (the latest I think). It’s terrible and slow.
