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

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.

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🤦

My phone lag after ios 26 update specifically in battery saver mode and low bandwidth network.Some notifications doesn’t work if locked phone for hours I m using iPhone 15 pro max 1 tb

Since you bring it up, what is your battery health percentage? What 5 or 6 apps are consuming your battery power and CPU cycles that of course could be the cause of the lag.

It’s sounds like you’re having issues beyond just an iOS upgrade. Have you spoken to Apple Support ?

I updated to IOS 26.1 yesterday and it is horrible. I wish I never would’ve updated my phone.

Let Apple know your thoughts here:

It’s the worst update ever. Have to select icons multiple times before a response. Things are gone. Can’t block spam caller numbers. Etc.etc.

Same the battery is holding not more than 3 hours and the phone is lagging extremely. Non of the suggested reasons are or were present before the update. The phone has plenty of storage, battery health is at 87%, no jail break, no drops or incorrect handling.

Same, brand new iphone 13 pro max , battery at 100% life, no jailbreak, no temp changes or drops. Super good condition, before updating to newest IOS it was so fast and good. Now it got laggy and phone is starting to heat even and extremely laggy. Things load slow. iPhone storage 512 half full.

I have an Iphone 13 and my available storage is 132GB. My battery health is 91 even after 3 years of usage which means i have been taking care of my iphone pretty well. Still after my Update my Iphone faces many lag and few apps are not responsive at times.

Before updating, my iPhone was running smoothly without performance issues. However, after the iOS 26 update, the device now feels unresponsive, and simple tasks take longer than usual. This is especially disappointing given that I rely on my iPhone for both personal and work-related activities.

I kindly request Apple to look into this matter and provide guidance on resolving the performance issues caused by the update. If this is a known issue, please advise whether a fix or patch will be released soon.

I have always trusted Apple for its quality and performance, and I hope this matter will be addressed at the earliest.

Thank you for your attention and support.

I have the same problems. It even goes to an extent where the screen brightness suddenly significantly drops down, and I am almost unable to read anything.

I am running an iPhone 13 Pro and considered, switching back to my old Pixel 6 since this phone handles all the updates perfectly fine
