Why you might want to disable Siri

Siri is Apple's voice assistant — the feature that listens when you hold down the home button or say "Hey Siri" and then responds to your spoken requests. Most people leave it on, but you might want to turn it off if you accidentally trigger it often, prefer not to use voice commands, or want to prevent others from using it to access your phone.

Disabling Siri is straightforward and takes less than a minute. You have two options: turn off the "Hey Siri" voice set up so you can still use Siri by holding a button, or disable Siri entirely so it does not respond at all.

Key Takeaways

  • You can turn off "Hey Siri" voice set up while keeping the button-press method, or disable Siri completely depending on your preference.
  • The settings are in the Settings app under Siri & Search, which is the same place on all recent iPhone models.
  • Disabling Siri does not delete any data — you can turn it back on anytime by reversing the same steps.
  • If you only want to prevent Siri from responding on your lock screen, that is a separate toggle in the same menu.

How to turn off "Hey Siri" voice set up

This method keeps Siri available if you hold down the home button or side button, but stops it from listening for the "Hey Siri" phrase. Open the Settings app and tap Siri & Search. You will see a toggle next to "Listen for 'Hey Siri'" — tap it to turn it off. The toggle will turn gray, meaning the feature is now disabled.

Your phone will no longer wake Siri when you say "Hey Siri" out loud. If you change your mind later, return to the same screen and tap the toggle again to turn it back on.

How to disable Siri completely

If you want to turn off Siri entirely so it does not respond to voice or button presses, open Settings and go to Siri & Search. Look for the toggle labeled "Siri" at the top of the menu — this is different from the "Hey Siri" toggle below it. Tap it to turn Siri off completely.

Once you do this, holding the home button or side button will no longer open Siri. The voice assistant will not respond to any command. This is the most thorough way to disable Siri if you do not want it active at all.

Turning off Siri on your lock screen

You might want to keep Siri on overall but prevent it from working when your phone is locked. This stops someone who picks up your locked phone from using Siri to send messages or access information. Go to Settings, tap Siri & Search, and scroll down to find "Allow Siri when Locked". Tap the toggle to turn it off.

Now Siri will only work after you unlock your phone. If someone tries to use it on the lock screen, they will get a message saying Siri is not available.

What happens after you disable Siri

Disabling Siri does not erase anything or affect how your phone works otherwise. Your messages, photos, and all other data stay exactly as they are. The only change is that Siri stops responding to voice commands or button presses, depending on which option you chose.

If you disable Siri and later decide you want it back, the process is identical — just return to Settings, go to Siri & Search, and toggle it back on. There is no waiting period or confirmation required.

Siri settings on different iPhone models

The steps above work on iPhone 6s and newer, which is when Apple added the "Hey Siri" feature. On older models, you can still disable Siri by going to Settings and tapping Siri, but you will not see the "Hey Siri" option because those phones do not support voice set up.

If you are using an iPhone with Face ID (iPhone X and newer), the side button controls Siri instead of the home button. The settings menu is the same — only the physical button you press changes.

Frequently Asked Questions

Will disabling Siri affect Siri Shortcuts?

Disabling Siri will prevent Siri Shortcuts from running through voice commands, but shortcuts you have set up to run on a schedule or through automation will still work. If you only want to stop voice set up, turn off "Hey Siri" instead of disabling Siri entirely.

Can I disable Siri just for certain apps?

No, Siri is an all-or-nothing setting in the Settings app. You cannot turn it off for one app and keep it on for another. Your options are to disable it completely, turn off voice set up only, or prevent it from working on your lock screen.

What if I accidentally press the button that opens Siri?

If you keep Siri on but frequently trigger it by accident, turning off "Hey Siri" solves the problem for voice set up. For accidental button presses, you can disable Siri entirely, or straightforward press the button again or tap the X to close Siri quickly.

Does turning off Siri save battery?

Disabling Siri may save a small amount of battery since your phone is no longer listening for the "Hey Siri" phrase, but the difference is minimal on modern iPhones. If battery life is your main concern, other settings like screen brightness and background app refresh have a much larger effect.
