Slow performance and lag after iOS 26 update on iPhone

After updating my device to iOS 26, I have been experiencing significant lag across apps and system settings. The performance has dropped noticeably, making the device feel slow and unresponsive. This is affecting the overall user experience, and I would appreciate guidance on whether this is a known issue or if there are recommended steps to resolve it

Had the same issues as OP, waited 3-5 days for the indexing to finish and still have some lags, but what worked was, I went on Setting - Accessibility - Display & Text Size - Reduce Transparency,

Turning it off, quiting setting, and then turning it on again, seems to make the phone run better. Everything is snappy again. Maybe it’ll work for you too.


I’m on iphone 13 128gb with 24gb of storage left.

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?

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.

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:

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