Slow performance and lag after iOS 26 update on iPhone

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 🙃🤷‍♂️🤔

(iPhone 16 Pro, 512GB, 223GB free storage)

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?

I updated my phone around 2-3 weeks ago and i’m still getting significant lag throughout apps, the most noticeable being Roblox, Discord and my work app. However i am using an iPhone 13 which could be the case but the phone was working perfectly fine before updating.

Im having the exact same issue! I have the IPhone 15 Pro (honestly this phone’s camera is so bad I shouldn’t have chosen this one but alas) and I’ve experienced more hardships than advantages with the new update. Had anyone experienced any of the specific issues below? I wish I could undo it.

1. The first is that I have trouble finding photos using search and my pics and videos don’t sync onto the cloud as easily or frequently. With the old version I could search for something and find what I was looking for but now the results are warped.
2. The second is that I have experienced significant battery depletion. My battery health is normal yet with this update, I feel like I am bleeding battery all the time
3. The third - GLITCHING AND LAG IN ALL APPS. So much lag on across all apps and specifically glitches with messages app. When I type it’ll just glitch and spaz out. I can say this has ever happened before.
4. connectivity to internet too. The fourth thing I’ll add is that my MacBook Air and iPad both connect then disconnect to the WiFi. I know it’s the update that’s causing this because as soon as I updated my MacBook, my Internet stopped working as it would connect then disconnect connect disconnect so thinking my computer was broken. I got out my iPad, which did not have the new update and no issues however I did update my iPad to double check and see if the same thing would happen and sure enough the same thing happened.

What do I do?

Honestly, there’s no need to be a smart Alec. We all know how to update our apps. I am still having lag and battery issues after the second update and I have an iPhone 15. I update my apps every couple of days. What’s your solution now?

even after the brand new iOS update 26.0.1 I am still having severe lag and my calendar widget will not show scheduled appointments that are definitely on the calendar. This is getting to be bad enough for me to start looking for other devices that are not Apple. And I have been a solid Apple user for years.
