Siri Significantly Downgraded After iOS 18.1 Update Rollback – Major Functional Limitations

Yes, I’ve already checked Settings > Apple Intelligence & Siri, and Apple Intelligence is turned on. I’ve also restarted this setting multiple times to be sure.

In the earlier version I experienced (most likely iOS 18.1), Siri appeared with a bordered square overlay that covered the entire screen. It felt immersive, intelligent, and clearly connected to a more powerful assistant—possibly ChatGPT or something similar. I was able to give it system-level commands like shutting down the device, and it executed them flawlessly.

Now, after a recent update or rollback, Siri has reverted to the previous behavior—with just the small glowing orb in the bottom-right corner. It feels like a complete downgrade in terms of intelligence and functionality. Around 90% of the time it just says it can’t help or that the command is beyond its ability.

Also, just to clarify — when you ask Siri to shut down your iPad or iPhone, does it actually perform the command for you? Or does it also respond with something like “Sorry, I can’t do that”? I’m really curious to know if this limitation is happening for everyone or just specific users.

This downgrade is frustrating, especially after seeing what Siri was truly capable of. I really hope this isn’t the final version and that the enhanced version of Siri (or Apple Intelligence) returns in a future update.
