IOS 17 is TERRIBLE to say the least! I have iphone 12 and it is running like an iphone 3! Super SUPER laggy no smoothness whatsoever switching between apps.. even the keyboard is extremely laggy im furious and decided to switch to android this is extremely frustrated to say the least.

I have an iphone 14pro and after updating to iOS version 17.03, it’s been so choppy and laggy. Also, when connecting to my carplay, my phone calls are off. People are getting cut off or not hearing me. Never had this issue until this update. My battery is good, have plenty of storage, and so on. Please advise!

R U kidding Apple?! Are we going backwards?

Upgraded perfectly fine 13 pro w latest ios16 to 17.1.2 cause of scary stories of bug fixes and only available to ios17 but man do I regret this move!

Two days after indexing and whatever, phone feels and behaves like an iPhone 6s. I'll make an ig and YouTube video showing iphone 12 mini w ios 16 and 13 pro ios 17 how they open and switch apps... This is unacceptable and counter productive.

If ios17 has some hidden code to force use to buy latest product, I'll switch to android after using iPhone since 2007.

Wife has a Samsung s9 who knows how old but sprints apps opening and overall operation. This is unbelievable.

My iPad and iPhone 13 are seriously slow ever since IOS17 update. Is there a fix?

I have the same issues, not only on an iPhone 13 but on a wi-fi iPad Air 5. Both were running perfectly on ios 16 but one of the ios 17 updates has caused freezing, slow updates and poor performance on both. they both have plenty of storage (96GB free on the phone and 142Gb on the iPad. If Apple won’t fix the problem then why don’t they resign iOS16 so people can downgrade. It’s pretty bad when you spend the kind of money that iPhones and iPads cost and then get poor performance due to the software.

I did not face any significant issues after updating to IOS 17 or 17.1.

After updating to 17.2 the phone app is super laggy. If I search a contact it takes few seconds to show up. And even when i dial a number there is a lag. All the basics have been done like restarting, closing apps, enough storage available etc. Any help appreciated

Yeah this is definitely unacceptable, I have an iPhone 13 Pro 512 GB and it is extremely laggy, especially in iMessage and keyboard it's unbelievable.

I'll be typing something in two minutes later it finishes it, dictation does the same thing, and trying to select text and copy things is absolutely ridiculous, it's like having a 25-year-old phone but paying $1500 for it!

fix this Apple please immediately!

Same issue here. iPhone 13 mini w/ software + apps up to date + 100gb free space + 89% battery capacity. Tried restarting, force closing apps, resetting settings, etc. Does not resolve the lag problem.

One of the iOS17 updates created this issue. Was never like this on iOS16.

Everybody is experiencing this issue. It's driving me crazy the phone is super slow. My main work is with my phone, and Ican't function like this. I'm losing it. I'm about to switch to Android.

I have the same problems particularly after charging. Slow keyboard, excessive power drain, slow or unresponsive Home Screen, Apps or iPhone crashing. Apple needs to engineer a fix. It seems the latest updates have nearly rendered my iPhone 13 unusable!!!! Definitely disappointed with Apple.

Same here, ios 17.2.1 on iPhone 12 pro max.

the keyboard is so slow and laggy, it looks like using the iPhone 4 with ios 7.

The battery health is 92% and the phone need to be charged 2 times a day.

ios 16 was laggy too, but at least my battery was lasting a decent amount of time and I could still write messages the right way.

This is NOT a normal behavior, 1450€ for a phone that is more laggy than a 10 years old phone.

Apple needs to fix all this, I’m considering to stop being an Apple user after 10 years.

And stop providing false fixes like restarting the phone and resetting the keyboard.

The price is rising and the service quality is getting worse year after year.

I was advised to:

(1) Reset the dictionary back to the default (for me, that is just English)

(2) Make sure all apps are turned off

(3) Restart the phone

(4) Test the lag whether still happening

(5) Add back dictionaries needed.

It seemed to work for me thereafter.

Additional step suggested was to turn off the Predictive text in Keyboard as part of the above, then add it back in after restarting the phone.

They removed my post for stating basically the same thing.

It has been so bad that I have to almost reboot it every day. What a shame to see the quality of IOS going down this path. Same issue, excessive battery drain, heating issue while phone is idle, etc etc.
