How is iOS 26 in old iPhones like 11 Pro Max, 12 mini, and 13?

Will they be slower, laggier, buggier, etc.?

Thank you for reading and hopefully answering soon. :)

I did not notice any real issues on my 11 Pro Max. There were a few instances where animations would stutter or catch briefly, but otherwise it ran fine for the week or so I had it on the phone.

I decided to trade it in for a 17 Pro Max this year because I’m guessing iOS 27 will not support it and expect a significant drop in trade in value when the current iOS was not supported. Otherwise I would not have traded it in as for everything I did it was fine.

No issues on my iPhone 13.

My subjective experience with an iPhone 12 mini, which I accidentally upgraded to iOS 26, is that general operation is a bit slower. I haven’t actually timed anything. Apps seem to take a bit longer to launch. Notifications are slower to appear and to disappear from the Home Screen. Animation in games that used to be smooth are now a bit jerky or stuttered.

Whether the Accessibility options to flatten Liquid Glass (Reduce Transparency and Reduce Motion) are on or off doesn’t seem to make any difference.

FWIW

I am delighted with v26 on my 12 pro max. It far outshines Liquid Glass on macOS.

Ugh. I am not looking forward to v26 since Apple is nagging others and me with its v26.1 release daily (leave us alone – we will upgrade when ready). I am thinking v18.7.2 is the last one for old iPhones that can run v26. V26.2 is coming out any day (not today). I just want fixes and not new features. :(

I did the long upgrade overnight during my sleep. I briefly tried and don’t like it already. It feels slower. I cannot seem to turn off the visual effects (fades, animations, etc.) though. My home screen is too bright in dark mode! I checked accessiblity and display settings (e.g., liquid glass’ tinted), but still annoyed. Are there anywhere else to look to disable more? :(
