Slow performance and lag after iOS 26 update on iPhone

I have the same problems. It even goes to an extent where the screen brightness suddenly significantly drops down, and I am almost unable to read anything.

I am running an iPhone 13 Pro and considered, switching back to my old Pixel 6 since this phone handles all the updates perfectly fine

Just had Apple delete my previous post because I mentioned it might be a scam for us to buy a new phone well to whoever deleting my post I wouldn't think it's a scam if my phone was performing the same as it was before the update just seems a bit convenient

I have iPhone 16 pro max and after updating to iOS 26 my device has significantly slowed down. I am experiencing lag and sometimes the screen gets stuck for a while. today morning I even had my Bluetooth disabled and It was not letting enable it. I am attaching the screenshot

My iPhone 13 Pro after updated has to slow n lag…even I can’t make any call or answer someone call…I was shocked my iPhone became an Android phone…. Service inconvenience…I missed my iPhone 4! Disappointed ios26

Amazing! That really worked like magic ✨🙌

My iPhone 16 Pro has been SUPER lagging the past 10 days, since I updated to iOS 26. FaceID has been extremely slow at loading and registering my face every time I've picked it up, since the last update. But after using this "hack" it seems instantaneously more responsive at registering my face!

I didn't turn it "off and then on again" though, as mentioned. I turned it on, restarted the app, and then turned it off again. It seems like it has improved the speed and responsiveness for sure. Doesn't make much sense to me why that would work, but I'm happy it did 🙃🤷‍♂️🤔

Same here. After 10 days my device is slow to open from the lock screen, and very laggy, probably thanks to all the pointless animations and “dynamic” nonsense. I’ve done my best to switch as much of them, and rubbish Liquid Glass, off as I can but it’s still there. Not to mention how iOS26 has killed Safari…

I’ve experienced the lag as well. I also experienced a lot of issues with my bookmarks. I’m being forced to log in to sites I always left open. Also, they are taking h longer to load. Yesterday I was experiencing the failed to send text messages as well. I wasn’t aware that an update could take 3-5 days to settle. However, I’ve experienced these issues long after the update

Add me to the list of users suffering from severe lag after the update. I noticed it with just trying to move apps into folders - completely unresponsive when I try to move apps. I so hope they are working on fixing this, since the issue is so severe!

Just look at the reddit threads,

Yea, that is the answer. You will also learn the earth is flat! Are there any other conspiracy theories that you have found there? When you speak of misinformation, you really need to consider your sources.

After updating my iPhone 15 pro max to iOS 26, my phone’s battery performance has become terrible. Before, it easily lasted around 14 hours, but now it barely goes 8 hours, My battery health is still 92%, so this clearly isn’t an old battery issue.

Hi, I have an iphone 15 plus , and I updated on that day when ios26 was relased but still until now I have lag , battery is drain just using normal apps and making phone calls , and after update my battery healt just drops at 87% from 90% at just only 310 charge cycle , its not normal for a phone that I pay almost 1k euro… I had updated ios before but this ios26 is just ….

My trusty 15 pro max is slower and laggy compared to my fiancé s10 plus thats very old, the old ios theme looked classier and had a mature look and design.

A friend of mine got a 17 pro with the same laggy situation on ios 26 and he got an update that fixed that why this is not pushed for the "older" devices looks like the usual apple strategy to make older device look bad compared to the new ones, it looks like they purposely induce a feeling of age that might force you to buy the new shiny ones

I as well have been having issues with the new update on my iPad. It’s starts lagging and going to apps that was not clicked on. Research says that it can also be because of the older version of the device but that device shouldn’t be on the list for the update if it’s going to do that. My device has been doing the same thing since it was updated. It needs to be an update to fix the bugs or have a way to remove the update.

this is happening to me too. im sitting here having to use my macbook because my phone is so dang slow and i keep getting disconnected from my wifi. i updated 3 days ago and its still a problem. if its not fixed soon im switching to andriod. apple is seriously always having issues. i have been an apple user since the first phone came out. im ready for change.

I have the same problem and I own an iphone 16-pro, which i bought a few months ago with little data on it. Before the update -a few days ago- the mobile was super fast. Now it behaves like an old mobile that moves very slowly having a few seconds lag before opening something. I want to downgrade from ios 26 to a previous version, is there a way?
