Slow performance and lag after iOS 26 update on iPhone

I have to restart constantly. I am questioning everything about my devices that I once depended on. The performance is abysmal.

iOS 26 is complete garbage. My phone is lagging on every app, slow charges, and has become a nightmare to operate.

I had a big problem: when I opened a game, sent a message, or switched to another game or app, it started lagging, but if I did that again the lag stopped. How can I fix that?

I have the same exact issue some the update. Phone is slow, freezing up, and even shutting down

My iphone has been so glitchy with multiple frozen screens especially in photos. Is this designed obsolescence by apple with the new phone release?

Fix this please I love iPhone but this new update is ridiculous

ios 26 is the worst upgrade ever. The glass reflection is so annoying.

It’s been a long time since I’ve updated my phone and my apps are STILL lagging especially my keyboard. I have lots of space left in my phone and use the iPhone 14 Plus. They need to fix this issue

My phone when recording is lag

I was using version 18 it was fine but I updated to version 26 and it started lagging apps scrolling is lagging even webpage scrolling is also lagging. I did not test till now on games.

what if it’s been 3 months and it’s still laggy when I play high quality games? I have an Iphone 14

Good news everyone. I tried to update to IOS 26.1 official released today and the lag issue has gone. Tested with 3D games.

Same. iOS 26 and 26.1 on the 17 pro max is awful. So buggy, inconsistent behaviors throughout the software. Awful. Wish I had never upgraded. A trillion dollar company and this is what we get

Omg thank you so much!! I feel a huge difference since i toggled off Apple AI

Me too! Sucks. I shouldn’t have to do all theses things with a brand new iPhone 17.
