Slow performance and lag after iOS 26 update on iPhone

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.

I am facing same issue with my iPhone15 too as phone is drastically slow post upgrade. Is this is upgraded OS or a way to force users to buy new phone. Never felt that Apple work in the way Android generally does to slow down performance using OS upgrade.

I downloaded iOS 26 on my 16pro and it is unbearable to use. I can’t Apple Pay as while it is thinking the app times out. I tried to open a website on Safari. I took a shower and it was still trying to open it.

How do I get 18 back?

After update i cant block cookies or java scripts

if i block the reading web page collapses

adds comes on top of the page and cant read anything

some times I can’t close the pages ,there used to be a kill button to close all tab

i feel like the web page is controlling our settings

Definitely Lagging issues. Apples performance over the years has been slowly dropping. More crashing apps, lagging speeds even with new devices and regular updates. We have all come to know Apple how it is today and put up with it. Newer tech which is fun and lifechanging, but still the glitches we just get use to. AirDrop between my devices is something I am used to these days. It sees the device, it says to send then it’s a waiting game or you have to back right out and try try again.

Ive been using the ISO 26 updated and still experience issues with majority of things. And my phone is only a couple of months old. But like many things, you get used to the problem and it feels like it has gone away.

Nope My phone is still laggy and mind it it was running perfectly all this while just after the update my phone started hanging up soo bad. I ve started to hate iphone as even my m3 ipad after the update is facing the issues its brand new …. the apps suddenly closes and more on my iphone14 plus maybe apple just trying to make people buy their new models scheme.

Definitely no lagging issues for me (and millions of others, or they would say so). So you need to troubleshoot the problem with your phone rather than making blanket false statements.

Hello Apple Team,

I recently updated my iPhone to iOS 26, and since the update, I’ve noticed that my battery is draining significantly faster than before. In addition, when using the Facebook app, scrolling through photos has become noticeably slow and laggy.

I’ve tried restarting my phone and closing background apps, but the issue still persists. Please look into this, as it’s affecting my phone’s overall performance and user experience.

Thank you for your attention and continued work on improving iOS.

It is always a good idea to read the posts before adding another comment and provide the details from what you have learned in those posts.

This site is a user to user forum, so Apple is not here to read your post. If you would like to address Apple directly, then it would be best to use their feedback link:

Product Feedback - Apple

For any app specific problem, that will have to be addressed by the Developer.

Two weeks have passed since the update. Have we been indexing since then, or what's going on?

Why can't they release an update without messing up our phones?

iphone 13 128 gb.

Apple can you patch this mess up? I would like to use my phone.

Beyond a joke now.

Still extremely laggy (iPhone 14 pro max) battery died during the night from 25% it has never done this before.

thankfully my contract is up and I will go over to Android. Apple customer service has been awful to deal with this issue.

Has anyone found a way to fix it as yet? Done everything that has been advised, thus far.

Please do not blame jailbreaking, dropping heat etc. I upgraded as required to use new apple watch and immediately after upgrade iPhone 13 connects to wifi but not internet. Even if only on cellular, it is very very slow and almost useless.

Apple should fix this!

iOS 26.1 is currently in beta and we cannot comment on the issues that have been resolved in that update as it is a violation of the terms for being a beta tester. If you have tried all the recommendations here then waiting for that update may be your only option to compare your results. I assume you have already Factory Reset your device using a computer to reinstall the OS in case of data corruption.

There is no reason for strong language, we are all civilized human beings that are perfectly capable of communicating with each other without any name calling, whether you feel it is appropriate or not.

Do they test older devices before releasing an iOS update? How far back do they go? For example, did they test iOS 26 on iPhone 11? Is there any interest on fixing these significant lagging and battery drainage issues? It seems to me that all they need to do is have the option to disable the heavy operating system's demands. I have more than 115 GB free and have tried every possible suggestion I find in here and on the internet, plus I have waited a few weeks, nevertheless nothing has improved for my phone performance. I’m at the point where I really wish I never updated.

I have already disabled Apple Intelligence and Transparency and the performance still feels like an Android device. It was super snappy, on the point, every single aspect of the phone was blazingly fast, even on my old iPhone 11 Pro was super fast, now i'm on an iPhone 15 Pro with a very odd and bad performance on the iOS 26 even after more than a month.
