iPhone lagging and slow after iOS 17 Update

I have the same issue. For me, I mirror my phone to my PC for streaming the game MLBB. I noticed that as soon as I updated to 17, the picture quality and frame rate dropped when playing games or mirroring to the PC.

I purchased, from apple, the lightening-HDMI connector and it worked beautifully up until the update. I tried to check if it was the cord and tested the same game on my iPad and it is crystal clear.

I think there is an issue with the new update and it definitely needs fixing. "troubleshooting" will not fix this, it's the OS that is the problem. Sorry.

I have this issue with a brand-new iPhone 15 Pro Max. Problem not solved

If you ever buy a new iPhone, never upgrades major iOS update more than twice. So iPhone 11 came with iOS 12, you should only be using iOS 15 or 16 maximum.

Fixed my CONTACT search issue. Thank you for the suggestion.

Go to SETTINGS, then SIRI & SEARCH, then CONTACTS, then SUGGESTIONS, then turn off “Show contact suggestions” button.

FINALLY. It is Siri that was slowing the search in Contacts. I didn’t have to shut Siri off, just had to unclick the suggestion button.

Do you get any solutions

my iPhone 13 is very laggy

it is 4 months old only.

Switching between apps looks very hangy type.

playing small game like mini milita looks very shaky.

it is on ios 17.3.1

wtf broo

iOS 16 was stable and smooth for me, and after update to 17.1 it’s stuttering and lagging in 35% of animations, stutters in scrolling, battery drain and more more more. After update to 17.4 I don’t see any improvements, think that it planned obsolescence, I don’t know. It’s my first device from Apple and negative experience, never buy it in future, gonna back to android

Today I proved my iPhone 13 Pro Max is the problem. I'm on my same home WiFi as my HP computer, my PlayStation 5, and my iPad Pro 2021.

My iPhone is SO SLOW!!!! Even the Amazon app is running slow and reporting "Something went wrong" and I have to refresh. The iPhone with iOS 17.2.1 (current) is reporting a Speedtest.net download and upload of

ONLY 14.0/0.83 Mbps.

My 3 year old HP Specter with Windows 11, says 88.5/11.5 Mbps.

My PlayStation 5, original model, says download of 83.2 Mbps.

And my 12.9" iPad Pro 2021 says download of 82.86/11.91 Mbps.

All tests done within 5 minutes. APPLE NEEDS TO STOP ADDING FEATURES AND FIX THE FOUNDATION!

I'm so very dissapointed I'm actually depressed. This is where Apple leaves us today. I have a few months left of T-Mobile credits until I can dump iPhones since my first iPhone 3.

It’s a how Apple gets you to upgrade to the next phone. By reducing your phone performance. They have been sued for this already

iPhone 12 mini control center slow as a **** sometimes. Today I bought a brand new iPhone 15 and… same lags here too. That lags starts from the iOS 17 to present latest 17.2.1…

So that definitely not about storage, not about battery and even not about factory reset

I have iphone 13 pro max.

since upgrading to 17.* everything is just slower.

i am an IT professional and computer engineer.

app shortcuts got noticeably slower.

app cold starts got slower.

battery life 10% shorter.

i kept on v16 as long as i could but…

Well 17.3 is here. I decided to try connecting Bluetooth to my car again to see if I could drop the iPod wire to my USb port to get music in my Honda. Worked for a few days and I thought, "It's fixed"! But silly me, thinking that Aside wanted to fix anything... same old missing album artwork, and random drop outs for up to 30 seconds. The music is still playing and my iPhone still says connected, but static drop outs continue. APPLE: I don't want to leave after more than a decade and my iPhone 3, but this toxic relationship has to end. Out of focus photos, audio issues WITH YOUR MUSIC AND PODCAST APPS, keyboard issues, incredibly bad autocorrection, and dropped calls. The implied usability of the phone is not reliable.

After reading this entire thread, ive come to the conclusion that there is a MAJOR bug in ios 17.

no issues at all

on my phone with previous ioss

and this lag thing seems to effect all phone models new and old.

come on apple... publish a fix or help us ALL downgrade to ios 16

Very laggy and choppy since iOS 17

I regret to update it. Only outcome for the new update for me is slowing down my iPhone 13 Pro

Experiencing the same problem here. It's incredibly frustrating to say the least! Ever since the latest update, my iPhone 13 Max Pro with 1TB has became really choppy and lagging especially when switching from one app to the other - lost all smoothness. As much as I love Apple products, the company seems to have some bad intentions! The ongoing Device Performance Litigation certainly doesn't inspire much confidence in Apple.

Hope they fix it soon. After many years of Apple products I’m getting sick of it. BTW, Experiencing the same issue with my iMac. Can’t even open regular websites anymore without getting frustrated!
