Notes App lagging after iOS 18 Update

Update on my part (1/20/25): The new formatting options that came with iOS 18 seem to be the cause. After a few posts here, I have now made the effort to change all the very long notes I know, which are nevertheless the ones with the new formatting, especially the ‘collapsibility’ of headings and subheadings. 

The app seems to work quite well again. Certainly not as fast as it should be (if, for example, the notes app on an old iPhone 8 with 16 iOS is even faster), but it significantly improves the really very limited usability. 

Perhaps this can help some of you until Apple has the courtesy to fix the issue.

When I went into accounts then iCloud then notes and turned off the sync a pop-up window came up to confirm “delete from my iPhone“. So this was not a solution in my book. I can’t afford deleting them from my iPhone and taking any chance I might not get them back. If I remove the app from my iPhone I’m afraid the same thing will happen. Why can’t they just fix the software?

Since apple has been ‘playing dead man’ on the subject for months, I would rather not hope at the moment. I assume that it simply affects too few users in Apple's eyes. Which of course doesn't help those of us who rely so heavily on Notes.

no bugs in ios18 then

Thanks a lot, worked for me and I have 3000 notes, some of them quite large. I never had this issue in my desktop and laptop (mac), just in ios18. Really appreciate your help !

I just tried Settings, Apple Pencil, and turning off the two options (only draw with Pencil; English/Scribble).

So far that seems to have helped.

I turned off the internet, but large notes (>130,000 characters) still slow down, it is impossible to work. Turning off the internet did not affect it.

What do I do though, I donot have an Apple Pencil), and I am having problems with notes app, also ?

If I uninstall it and re-install it, will I lose everything in my iphone 12 iOS 18.1 Notes app ?

I always find it very interesting how some users have problems with extensive, long notes in particular. For me, the lags have nothing to do with the size or length of the notes.

It’s 11/29/24, and this issue has not been resolved in iOS 18.1.1

has anyone found a temporary fix?

For me, only notes with a large number of characters slow down. Notes with few characters do not slow down.

Maybe there aren't many people with 130,000 character notes, so most are doing well.

Where else can I type a bunch of stuff into my computer and then have it at my fingertips on my phone when I am out and about? I doubt I am giving up on notes anytime soon. Hoping for a fix

This seems to be improved in IOS 18.2. There’s no mention of it in the update notes. However I’ve noticed a major difference since the update.

I can only encourage everyone affected to report their problem with Notes to Apple customer service. As long as there is no pressure to suffer...

I see no logical connection between the change of view and format-related bugs. And the most recent version is 18.3 (you talk about 18.2).
