Slow performance and lag after iOS 26 update on iPhone

I have waited a week after update now and it's terrible. Many new serious bugs have appeared. The keyboard is utterly broken. Safari is almost unusable with Glass off (with Reduce Transparency). Often apps are unresponsive. Scrolling freezes. Etc

I upgraded iPhone 15 pro to iOS 26.1 ten days ago and safari is just DESTROYED. bookmarks and web navigates so slowly, lags exceed 6 to 10 seconds between click and action. I have gigabit fiber and eero 7 500 m WiFi speed so it’s definitely the operating system. Apple please fix ios26.1’s interminable lags.

You are not addressing Apple here. This is a user-to-user forum. Apple is not reading your post.

You can let Apple know your thoughts here:

I also am not happy with this new IOS. Just opening mail or messages causes serious lags in loading content or simply not loading at all and having to close and reopen the app. It also seems and has been in previous IOSs, to be less intuitive requiring more steps to complete the same tasks. Then the layout of controls on safari and other apple apps is difficult to navigate with way too many hidden actions. Finally, the liquid glass should have never made it thru beta testing and obscures the clean look apple products typically have. This is by far my least favorite update. Please fix it.

Yea, they did the same when updating my IPad, we have 4 phones all with great battery health, oodles of space and each one is laggy, unresponsive and and slower than the last update with the oldest one almost unusable. Won’t be updating again. They should issue a slimline upgrade which fixes security issues only with none of the ‘enhancements’ older generation phones struggle with.

And all that could be. But what’s in the past is done. You want to affect change? The path forward for those hoping to contribute to a better iOS in the future need to share their experiences and thought through the official Apple feedback channel.

iPhone 11 here, new original battery.

After 26.3 update, Apple Maps is lagging with its directions in background, screen off in my pocket.

I am missing turn directions, sometimes by minutes - until the phone wakes up again or something. Definitely an issue that was not there on 18.7.3.

Should I start using Google Maps instead? No i do not want to please…

The rest of functions is good as it was.

I have a new iPhone 13, fresh from the box, updated it to ios 26. Experienced significant lag. I noticed this to be related to the camera. Sometimes, when I open the camera, there's a significant lag and when I type on other apps I notice the keyboard is not responding. This even with just 2 applications open. I followed the recommendation here and observe the phone for a month. It's still the same. ***

You do understand Apple and Apple Support do not participate here, correct? Reporting bugs here in the community (Apple users) serves virtually no purpose. You can report bugs through the Apple Developers portal and Apple Feedback Assistant app (once you register to be a beta tester). You can also report bugs through the feedback link, but don’t expect a response from Apple Support, if using the link.

Here is the link to provide feedback,

If you register to become a beta tester, you will also receive the Feedback Assistant app.

Exactly, and that is the exact reason why I am refusing to spend another $1,200 to upgrade to the new iPhone 17. Buying a brand-new phone isn't going to resolve anything because this is a deep software optimization problem, not a hardware issue.

Our current phones are more than powerful enough, but the software is completely holding them hostage. Until Apple actually fixes these core system bugs and stops the battery drain, moving to a newer model is just throwing money at a broken system.

iPhone SE

Where did you have the Battery replaced?

If it was done by Apple, take it back to them. What you describe is common with the installation of a third party battery and if that is what was done, there is little Apple will likely do.

Tried resetting the iPhone and loading no backup make it a little better but the lag was still there.

using 16 pro max 1TB and feeling as if it’s an iPhone 6🤦
