Ios 26 update downgrade to ios 18.5 ios 26 is not satisfactory

Original Title: ios 26 downgrade to 18.5
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!

BTW, I used your User Tip in a User Tip I wrote today about Battery Health Decline (but did give you credit for it). Hope that's OK? It's linked in the WC if you'd like to read it.

I saw your comment and made some changes to the tip. It was never meant to step on your toes. You did a great job explaining when to charge an iPhone. I wanted something to address only Battery Health decline, which many people obsess and worry about.

In order for a thread to be locked, it needs to be inactive for a period of time. I don't believe we know the exact length of time, but I think it's about 60 days. You can unsubscribe from the thread. Or just settle back with your popcorn.

I believe thread locking is automatic.
But I find the thread hilarious, so I haven’t unsubscribed.
