Unfortunately, you can’t downgrade an iPhone to iOS 18.5 once it’s been updated to iOS 26.
Apple only allows installing versions of iOS that are still being signed — and older versions like iOS 18.5 are no longer signed by Apple’s servers. That means even if you have an IPSW file, the installation will fail because the signature check won’t pass.
If iOS 26 feels unsatisfactory, the best thing you can do is:
Once Apple stops signing iOS 26 and releases a new version (like iOS 26.1), you can only move forward, not back.
If you just want your phone to feel faster or more stable again, a clean restore from backup usually helps a lot!

You don't. As the previous seven pages of this thread would have told you.

After upgraded ios 26, battery drain very fast. Need to recharge full 3 times in a day. Earlier it was only single charge for full day. Not expected from apple this kind of glitch.
apple should think about seriously and provide option for switch to last version.
Apple has NEVER supported downgrading, and it's HUGELY unlikely they ever will. But you're not telling Apple what you think they should do here. Use this link if you want to tell Apple --> Feedback - iPhone - Apple

I’m very sorry to tell you that you are probably the hundredth person to point that out in this 11 page thread.
Hey lobsterghost1, I’m back to inform the masses that it was in fact apple inc. With the update of iOS 26 being released. The issue has resolved, I thank you deeply for “helping me” with my issue. I wish you nothing but the best in life and have a lovely 2026! 🥂
What you want to do.....you cannot do.
Sorry, downgrading the operating system is not supported

That will happen when Automatic Updates is turned on at Settings > General > Software Updates. Once updated, there is not a way to downgrade.

My iPhone has been updated to iOS 26.0.1, it has been so hard for me to use at 64 years old. I want to go back to the old system. I can't use a lot of the features.
You can't go back.

I want to downgrade from 26.0 back to 18.6 (or current program before 26.0), as 26.0 is a terrible look and hard to see icons.
I want to win the lottery and I actually have more chance of winning the lottery than you do of downgrading. Did you even bother to read ANY of the posts? If you had, it's been answered on every single page of this 10 page thread that you CANNOT downgrade. Instead of wasting your time and the time of others, read before you ask the same question which has been answered over and over and over and over.
No, it doesn't work that way.

Had you read the other responses in this thread, you'd know that's not possible.
You can't. Downgrading is not possible as explained previously in the nine pages in this thread.
