"iPhone 14 Pro Max very lag in typing messages: [...]By typing this messages it used up 15minutes to complete as the auto fill messages always misspelled and I have to type alphabet by alphabet and slowly in order to get the right words. It’s really not user friendly for me to type hundred of messages daily."

If Apps are Lagging...

Clear Space Using my User Tips:

See if you need to clear lots of space. System resources may be using up too much services, making it lag. Internal storage cannot be upgraded. It is what it is. So, the maximum internal storage capacity never increases, even if you upgraded your iCloud plan. Learn More here: What's the Difference Between Device Storage and iCloud Storage? Apple Support

Hmm, that’s nearly 80%, which is when Apple recommends you have the battery replaced. However, I don’t think the battery has degraded enough to where it should cause lagging.

I suggest you reach out to Apple Support:
