How to Downgrade iOS 26 to 18

Hello everyone,


I recently accidentally upgraded my iPhone to the iOS 26 developer beta. After using it for a few days, I found that the system has many new features. Unfortunately, my device is relatively old and not suitable for the latest iOS26 system version. Now I still want to roll back to the official version of iOS 18 that I am familiar with.


I have been using iOS 26 for about two days, and there are still many things that I am not used to. Can anyone share a clear, step-by-step downgrade method to restore my device to iOS 18 without losing important data?


Thank you in advance for your guidance or recommended tools!

iPhone 11 Pro

No, it’s not. I accidentally updated as well. I woke up 7 am this morning in December? Dark mornings picked up the phone so there was a red dot and I did the same and now I wish I hadn’t.. because it’s draining my battery my phone is relatively new.

It's completely normal for the battery to drain faster for a couple days immediately after an iOS update. Your phone has to work hard to reindex the millions upon millions of bytes of data. Give it a couple days for the indexing to complete.

Review the information provided by Apple here that would apply if you just updated this morning and will have another 3-5 days before you can make any judgements. You should be experiencing battery drain, lag in the UI, and the device will be warmer than normal during that time.

Learn to appreciate it! Really. Learn to appreciate the cliches, tapping and noting happens!I downloaded and in two minutes I had another download for the cliches which it didn’t take care of. Apple should do better! Don’t release something unless it works! I have blocked the upgrade on all my other devices.

Obviously, Apple should have listened to you and made sure that everything conformed to your preferences! It is terrible that they didn't do that! You should let them know:

You don't like iOS 26? Sure, fine. Preferences are personal. What is objectively true is that ios 26 has so many problems that having it running on my 13 mini is *painful*. Things as simple as TYPING do not work properly.


You won't allow to just downgrade? Also fine. But at least keep iOS 18.7 signed, leaving one final option to go back to a version that actually works, even though with a reset. I couldn't care less for the shiny items if I literally can't use my phone properly. Either this gets fixed in the next months or it will be the time I have to switch to another brand.


Planned obsolescence this obvious is just shameful. The fact they didn't even allow to install 18.7 to force upgrading to 26 is shameful. Hope enough people switch brands they make something about it.
