As long as you want.

How long can I stay on iOS 18 without losing security updates

You have already missed security updates in iOS 18.7.9 and iOS 18.7.10 which may or may not have been offered to you. If iOS 18.7.10 is being offered to you, you would want to install that for the latest security fixes.

If you don't see an option to update to iOS 18.7.10, that would indicate that security updates for the iPhone 11 have ended.

If I have to update, can I not update to the latest release of iOS 26 instead of 27?

No. If you could, you would see an option to update to iOS 26 on your iPhone. If your iPhone is capable of running iOS 27......the iPhone 11 is......the update will always be to the most current iOS version.

ALSO, Is 64GB of storage for an iPhone really ideal for an iOS version that will use 20-30GB?

No.

you get offered the latest supporting version for your device

you can stay with ios18 as long as you like, though security fixes will likely no longer be release for the iphone apart from in the latest version.

I have another iPhone XS, It has received iOS 18.7.10, and I wondered why mine didn’t, probably because the XS isn’t capable of running iOS 26.

Correct

By you just saying that 64GB isn’t ideal an iOS version that takes a lot of storage, What would your recommendation be?

Bare minimum of 128 GB. The new iPhone 18 comes with a minimum of 256 GB with options up to 2 TB. But, you can't update the storage on your iPhone 11 anyway, since it is fixed.

Even if you wanted to install iOS 27 on your iPhone 11, you would probably see a message that you don't have enough storage available to run the update.

Your iPhone 11 has done very well for a long time. I think you know what the next recommendation will be.

Yes, I have another iPhone XS, It has received iOS 18.7.10, and I wondered why mine didn’t, probably because the XS isn’t capable of running iOS 26.

By you just saying that 64GB isn’t ideal an iOS version that takes a lot of storage, What would your recommendation be?

I don’t want to use an out of date OS, but at the same time, I cannot just use roughly 10-20GB of my phone’s storage because of the iOS update, and I cannot afford to have it slow down on me.

Maybe recognize that you're using an iPhone released in 2019, 7+ years ago. And you bought that iPhone with the lowest storage level available. New iPhones Apple sells today, start at 256GB and I don't think that's enough for our future storage needs, so I now buy my new iPhones with 512GB. Storage needs will only grow, not shrink. So I'd be giving serious consideration to retiring your 7+ year old iPhone and buy a new one.

People just don't give enough consideration to the storage level of the phone they buy. Yet it's one of the absolute most important things to consider.

I have bought the phone 3 years ago, and I have wanted it to last as long as possible with application support, and I have committed to sticking with it until it loses all app support, and when absolutely nothing works with it, I’ll wait for 2 more years, Any way to prioritise security on iOS 18 and being careful without risking security? I only browse safari, and use applications from the App Store, and I rarely install new apps.

You may have only had the phone for 3 years, but that doesn't change the fact it's a phone from 2019. There's not much I can offer about prioritizing security in iOS 18 at this point. iOS 18 is now two years out from when it was released.

.

So security fixes stopped for my iPhone on iOS 18?

Right, any recommendation for how to be careful online while staying on iOS 18?

Good luck!
