Slow performance and lag after iOS 26 update on iPhone

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.

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.
