iPhone 16 Pro Max lagging after iOS 18 Update

SOLVED: Just got off the phone with Apple support to talk about my identical issues. They had me reset my phone but only the “network settings”. It solved the lag and Siri problem.

I suspect a setting carried over from my previous phone in the automatic transfer, which was cleaned up at network setting reset.

This needs to get moved to the top of the thread!!!!!

This solved all my crash issues as well. Easy fix and did not take long, may help a lot of people on this thread!

My phone is now working!

So after looking at the suggestions for a fix, I happily discovered that the reset worked perfectly for me. Suddenly Siri is working perfectly, there's no dictation lag, and I'm 100% happy with my phone. I strongly recommend this for everyone suffering lag on their 16 Pro Max (or possibly other models,) as this was a lifesaver for me. I'm sure other's have posted links, but here's a simple guide:

** Edit ** yeah, sure wouldn't want to share a youtube link that would help fellow users, would we, Apple? They removed my link, but here's the simple process:

1. press the volume up, followed quickly by the volume down button
2. press and HOLD right side button (top one, not camera button) until the screen goes blank followed by the apple logo reappearing. Then release. Done!

It's not always the iOS update's fault!  Many things can cause phone problems.  If you tell people you think it's an iOS update, it might make it harder to fix or find a solution for the real issue.

Remember, the right question often leads to the solution! Please look in the right direction.

iOS updates aim to enhance user experience, boost security, and fix bugs rather than disrupt core features. The majority of the issues after updates might stem from underlying, unmentioned factors. Updates won't typically alter personal data but may refine settings or features. Backup before major updates for safety. Review Apple's update details and backup advice for a smooth process.

Kindly consider checking your settings and addressing any device issues before attributing the issue to external factors. This could be a pure coincidence that the iOS update affected the iPhone functions.

Before initiating a standard iOS update, it's advisable to create a backup. Have you completed this step? If yes, proceed with the restoration from the backup.

I have the same problem with my iphone 16 pro max, when I try to take a picture the screen goes black and then the camera app crashes. A restart of my iphone fixes the problem temporarily until the problem is back.

Have been using my new iphone 16 pro for past few days and it continues to give me the spinning wheel on opening apps, trying to open most things in settings and my subscriptions was the last thing. Went to Verizon store all they could do was close open apps and suggest resetting to default. I have an older work iphone on Verizon and setting the two side by side the work phone has not issues. Very frustrating. The mirror function on my old iphone 7 works at home with my Samsung tvs, however, the 16 pro doesn't even find them, while on the wireless network. My take this phone back if a can and switch to another brand, ridiculous given it is version 16.

I am so glad I found you all. I upgraded from the 12 Pro Max to the 16 Pro Max. I am in full regret mode and I wish I had not turned in my 12 to Verizon. I can't seem to do anything on the 16PM. It freezes and restarts. I can't access iMessage, etc. Is this a bug fix issue or a hardware issue? (Please forgive my lack of knowledge.)

I went to the Verizon store yesterday.. and just checking the OTD total price... and wanted to think about it a week.. i was determin to get a 16 pro max and upgrade my 14 pro max.. but the reviews from all of you.. it looks like I will just keep my 14 pro max and just wait for the iphone 17 now...

looks like there are too many problems with the phone at this time... I wish I had better batter life and a better camera.. but having less problems outweights the benefits of a new phone.

I just bought an iphone 16plus and it lags so much and glitches , i updated to IOS 18.0 and it still lags!! When i go to the home screen it freezes and then lags a bit before returning to home. When i open safari theres a little split second of glitching, and when the phone is off and i try to turn it on, it doesnt turn on sometimes!! I have to wait like 10-20 seconds for it to turn on, even if i click buttons or tap on the screen!!

I am also having similar issues. Phone is little laggy compared to 13 pro max which I traded in. Was expecting a lot from 16 pro max... Screen little bit stutters when open the phone, animation is little off... Little lag in the OS as well. Hope software update fixes this..

My lags a lot too, it’s crazy. The camera crashes when you try to use it, it doesn’t really know which network to go on. You have to turn off your 5G in order to use Internet with the router, it hangs on everything.

iPhone 16 pro and iOS 18 lagging.

I recently changed from an iPhone 12 that had iOS 16 to this iPhone 16 pro.

I’ve updated the phone to iOS 18 but it still lags. Auto correct is bad, slow keyboard while typing. Apps close by itself etc I could go on for days. It’s just crazy how I’d buy a phone for 1100-1200 dollars and get this nonsense. I’m really contemplating changing it back to my 12. Nobody better say I don’t have enough space because it’s 256gb and I’ve only used up 61gb because of transferred space. And don’t even think of saying to force restart a new $1200 phone

Upgrading from a 13 Pro Max to the 16 is the least exciting Apple experience I’ve ever had.

I’m having major buyer’s remorse.

It is not our job to troubleshoot this problem with “better questions”.

A $1,000+ purchase should be flawless out the box.

Siri/voice-to-text is painfully slow.

Camera app has a mind of its own.

The overheating is true, it’s hot to touch but only sometimes.

Texting androids is glitchy: We now get “😊 at a Gif” instead of the smile being attached to the image.

I’m embarrassed, not proud of my new device.

So glad to see my misery has company.

Wow! I hope this gets better. Non stop lags, crashing, glitches, apps don’t work, iMessage has been going in and out , my contacts and favorites don’t work half the time, it usually takes a reboot or factory reset to fix, but it sucks because I feel like I’m resetting it all day long. Buyers remorse!

Fun Fact:

Apparently you can’t take a photo if you’re on a phone call connected to ear pods.

I’m not sure of the exact combination, but the phone spazzed out, disconnected, reconnected ARGH!

And you can’t take video while on a phone call anymore. Video with no sound, understandable, but no video at all? Why????
