Downgrading from iOS 26 to a previous version on iPhone SE

hi so i have ios 26, it’s not the beta it’s like the actual thing and I genuinely hate it. Is there a way to go back to like ios 18? i’ve unfortunately already backed up my phone with 26 and i hate this update so much that i’m crying from irritation. if someone could help and i can actually downgrade it would mean the world. I have an older phone, an iphone SE and ios 26 has made it a bit laggy and it makes it over heat. There’s also things that i find irritating that no one else probably does but it’s just i don’t think i can use my phone without getting frustrated that i updated it to this very ugly and disgusting ios. So please, if there’s any way to go back to 18 or whatever system i was on i’d be grateful. <3

Hey, I understand where you’re coming from. Sometimes, these big iOS updates can cause issues, especially on older iPhones like the SE. It’s frustrating when the phone feels laggy or the look isn’t your vibe. First of all, hugs seriously, you’re not alone in this! Is it possible to downgrade from iOS 26? Here’s the thing: Apple officially only allows downgrades to the previous iOS version during a very short window after launch, as long as they’re still “signing” that software. However, going all the way back to iOS 18 isn’t supported anymore, especially once your backup is on the new iOS. The system is designed to prevent downgrades for security and compatibility reasons. Even with technical workarounds, reverting to older versions usually won’t work because old iOS versions for the SE are no longer signed, meaning iTunes or Finder won’t let you install them. You risk losing all data since your backup is now tied to iOS 26 and is not compatible with iOS 18. There’s also a real chance of bricking or disabling your phone if you try risky “hacker” methods. What can help right now? If iOS 26 is causing your iPhone SE to overheat and lag, here’s a friendly checklist: Check for any app updates, as sometimes lag is caused by apps not yet optimized for iOS 26. If you haven't already, try a full restart (power off, wait 30 seconds, power on). Head to Settings > General > Storage: Delete unused apps, large message threads, or cached data. Disable Background App Refresh for most apps in Settings > General > Background App Refresh. Lower the screen brightness and turn off visual effects like motion and transparency in Accessibility > Display & Text Size. Make sure Low Power Mode is on, at least temporarily, to help reduce heat. If things are really bad, sometimes a clean reinstall of iOS 26 (factory reset, then set up as new, not from backup) can improve performance, but that’s a big step and wipes everything, so consider it a last resort. Cool iOS 26 features worth exploring. I know you’re frustrated, but maybe a few of these new features can help. Live widgets now allow you to interact with more widgets on your Lock Screen, like checking off reminders or playing music without unlocking. Advanced Focus Filters give you smarter control to mute not just calls, but also distracting icons and notifications based on work, sleep, or chill modes. Smart Detection for AirPods can switch sound profiles and even block loud noises on the fly, making older AirPods feel a bit newer. The Adaptive Home Screen finally sorts apps automatically by category, similar to the App Library, right on your main screen. Emergency SOS enhancements provide more reliable satellite texting if you’re in trouble, even for roadside help.
