iPhone 11 should i upgrade ios on my iphone 11?

it's a shame a signed iOS 18 is not available for those who, after upgrading to iOS 26, can downgrade if they decided to. Not how Apple does things unfortunately.

I have iOS 26.4.2 on an iPhone 14 (6GB RAM) and an iPhone SE 3 on iOS 18.7.8 (4GB RAM). Even with the extra RAM, there is still a bit of lag on the iPhone 14, but not on the iPhone SE 3.

For example, when I'm browsing through the "Offers" section of the AmEx app, whenever I add/save an Offer, there's a slight lag in saving it. After the Offer is saved, I'll swipe up to see what other Offers are available. When I do, there's a slight stutter before I can continue to swipe up to see other Offers.

I do not have this lag and stutter issue on the iPhone SE 3.

I also have lag with the Apple Stocks app on the iPhone 14. It seems to take an extra second or two for it to update. No such problems on the iPhone SE 3.

I don't think it's a RAM issue with iOS 26. It just sucks. I'd downupgrade my iPhone 14 to iOS 18.7.8 if I could.

Interesting how I have none of those issues you describe on my 11 Pro Max with iOS 26. Yet your 14, which is three years younger then mine does.

Of course, I'm not doing what you are and not using the same apps.

Even if you have the 512GB iPhone 11 Pro Max, I don't recommend upgrading to iOS 26.x

Just stay on iOS 18.x and make sure to scroll to the very end of the Software Update page to see iOS 18.7.8 [or iOS 18.7.9 in a few days time] and also disable developer beta and public beta updates.

I have an iPad 9 and in normal task it doesn’t lags only time it lags is in when I open a heavy website in safari and then it lags horribly 3gb ram is a bottleneck for A13 I think

so i have a 64gb iphone 11 purple on 18.7.2 i keep getting notification to upgrade to 26.4.2 should i update or leave as is i know sometimes when you update you risk a slower phone with no way to downgrade

If you don't update, you have security issues.
