iPhone 14 became unresponsive after iOS 17.2.1 update

Same issue with 13 pro max , can’t make call or receive messages it is an iso bug and Apple needs to address this and fix , especially with how expensive their phones are! I’ve bought a new iPhone and the same issue feels like I’m just throwing money away

I'm experiencing the following, after iOS 17.2.1 update on my iPhone XS Max:

• Frequent freeze/crash in Apple Calendar app -- especially if I select an appointment for details/edit
• Inability to search Contacts (just freezes)
• Set-up ("connecting...") for outbound calls takes > 30 seconds
• iPhone battery lasts about 20% less time than before update
• Apple Watch battery lasts about 40% less time (dies after about 8 hours), when corresponding watch update applied

My iPhone is InTune-managed by my employer -- so suggested incompatibilities may be the culprit.

Actions I've taken that have provided no improvement:

• Change primary cellular provider (I have AT&T SIM and Visible eSIM -- selectively disabled/enabled each)
• iPhone "hard re-start"
• Reset network settings
• Substantial reduction of Contacts duplicates and overall Contacts entries
• Settings->Contacts->Siri&Search: Turn off "Show App in Search" and "Show Contact Suggestions"

We are using InTune as well. This is the only device/user we’re having this issue with

Yes I have the same issue. Called apple support. They say it is caused by 3rd party software and they can’t do much — I don’t agree with them, it is obviously triggered by the update to 17.2

I want to believe that in ios 17.3 they will correct it... my iPhone 12 run like a 2010 Android.

We saw massive improvement with phone app performance with 17.4 RC build. With 17.4 already available, it is expected to fix the issue.

I had this same issue and my issue is coming from the device management from my company. We use the MSFT Intune Company Portal app. When I remove my company’s device management on my phone then the phone works fine. My company is now pointing the finger at Microsoft and Apple and Microsoft and Apple are pointing the finger back at my Company. Good times.

experienced this earlier actually. i've been experiencing issues w my 14 pro since the second it updated. i'm in alabama - we have gotten heavy snow and ice today, it won't be under freezing again for 3 days. the roads aren't drivable and i live alone. we've been warned to expect power outages due to the heavy ice. my phone froze earlier today with the lock screen on but backlight dimmed almost black, battery got SCALDING hot, and i could not restart it. force restarting didn't work, i attempted multiple times over the day. i had to let it just sit there for hours until the battery finally died, then wouldn't turn on for another two hours after putting it on the charger.

my parents live ten minutes from me and have a backup generator and fireplace and my stepdad has a truck that could make it to me if it was absolutely necessary but my car wouldn't have made it, all of our roads are covered in black ice. my wifi has been knocked out due to the weather so i spent the entire day worrying about what i was going to do if i lost power because had that happened and the phone never turned back on i would have no way to contact them at all. obviously it's fine now but this is unprecedented weather here and a scary situation to be in when you're unable to contact anyone.

this is on top of all the same issues you've mentioned as well. i've had an iphone since 2008 and have not had this many problems with an update since ios7, but it's interesting how it seems like every update for the last few years has barely addressed any of the real problems and created several that are substantially worse.

We manage our devices via Intune, however I don't think Intune is at fault. I've read some other posts where users with large numbers of contacts are seeing duplication happening. When duplication happens with large numbers of contacts, battery drain occurs, contact searching fails and WhatsApp calling also fails.

We sync around 4k contacts to the device via the outlook app. Microsoft have an article around duplication and that Apple needs to provide better sync capabilities as (even before recent updates) duplication can occur.

As I understand it, Apple created some contact issues in 17.1 (we didn't see any issues), but resolved these in 17.2 (when we started to see duplication issues, battery drain etc.....).

If you delete contacts and turn off sync, issues go away. This isn't a good solution though as WhatsApp then cannot find contacts to call etc.... WhatsApp cannot discover contacts via outlook unfortunately.

I see someone write about restriction policies in this post, but have not tried that yet. Also, not tried siri services disabling for contacts. Something I will test, however these restrictions are probably not something we want to change.

Overall, duplication of contacts seems to be causing lots of issues. The contacts app appears to be very inefficient, especially since recent updates. I suspect contacts app is consuming lots of resources on the device, certainly noticeable when deleting and recreating contwxts, as the device gets quite hot.

One other thing I need to test is to recreate contacts via outlook, export these contacts from the contacts app, delete all contacts and disable any syncs, finally import the exported contacts. Not ideal, but if sync is causing all the issues with it, it will at least give users a point in time contacts list that will not update automatically.

Quick edit - worthwhile checking how many contacts you have in the contacts app. If it is unreasonably large and increasing, you probably are experiencing what we are seeing. Also, check the amount of storage the contacts app is using, perhaps how match battery it is using too.

With the GA release of iOS/iPadOS 17.4 today - it would appear that updating to this version has improved the battery life and performance issues for the scenario where users have 4000 - 11000 Contacts (Outlook / iCloud).

Testing on my (Intune managed) devices seems promising thus far - has anyone else updated and have seen similar results?

Well, just confirming that from our experience, 17.4 has indeed resolved the issue. All good! :)

There may be some isolated cases where performance is still sluggish (particularly with Outlook) - for these devices, try factory resetting them (while on the 17.4 GA build) and then register them back to MDM from scratch. This had fixed the small handful of those that had persistent issues.

We are having the same issue with Intune / IOS 17.2.1. Has anyone been able to solve the issue?

I have been unable to solve this problem.

I have iPhone 14

after update iOS 17.2.1 I am facing issue with my contacts which greeting very slow response.

not know what to do with this issue.

How can I fix it? Same problem very slow since it was updated last night. iPhone 14 Pro.
