It happens to the best of us. Maybe you just finished a messy cooking session and your hands are covered in flour, or perhaps—worst case scenario—your display has completely given up the ghost and won't register a single tap. You're staring at your expensive iPhone 15, and you just need the thing to shut down. Knowing how to turn off iPhone without touching screen iPhone 15 models isn't just a party trick; it's a genuine accessibility necessity and a troubleshooting lifesaver.
Most people assume that if the digitizer (the part of the screen that senses touch) dies, the phone is a brick until the battery drains. That's actually not true. Apple built in several backdoors.
Siri is your first line of defense
Honestly, the easiest way to handle this is just to ask. If you have "Hey Siri" enabled, you don't even need to reach for the phone. This was a feature Apple quietly refined a few versions of iOS ago, making it much more robust for hands-free power management.
Just say, "Siri, power off my iPhone."
The system will prompt you with a confirmation. It usually says something like, "Just to confirm, you want to power off this device?" You respond with a clear "Yes." Boom. Done. The screen goes black, and the logic board shuts down. If your voice triggers aren't working, you can long-press the Side button (the one on the right) to summon her, provided your buttons are still functional.
But what if Siri is being stubborn? Or what if you're in a loud environment where the microphones can't pick up your voice over the ambient noise? That’s where things get a bit more mechanical.

The hard reset: The brute force method
Sometimes the software is so frozen that Siri can’t even hear you. In these moments, you aren't really "turning it off" in the traditional sense; you're performing a forced restart. While this technically reboots the phone rather than leaving it off, it is the most reliable way to kill a frozen process without using the screen.
To do this on an iPhone 15, you have to perform a specific "dance" with the physical buttons. You need to be quick.
First, click and immediately release the Volume Up button. Second, click and immediately release the Volume Down button. Finally, press and hold the Side button. Keep holding it. Don't let go when you see the "slide to power off" bar appear on the screen—remember, we're assuming your screen doesn't work or you can't touch it. Just keep holding that Side button until the screen goes completely black and the Apple logo eventually reappears.
If your goal was to leave the phone off, you have to be precise. The moment the screen goes black before the Apple logo pops up, let go of the button. It's a narrow window, usually about 10 seconds into the hold.
Voice Control: The pro-level accessibility hack
If you’re someone who frequently deals with mobility issues or simply wants a more permanent hands-free setup, "Voice Control" is a different beast entirely than Siri. While Siri requires a cloud connection for many tasks, Voice Control is a local, on-device accessibility feature.
If you have it turned on in Settings > Accessibility > Voice Control, you can literally command the phone to perform gestures.
You can say "Show grid," which overlays numbered squares on your screen. If you know the "Slide to power off" bar usually appears in the top third of the screen, you can tell the phone to "Tap 2" or whatever number corresponds to that area. It sounds like something out of a sci-fi movie, but for users with motor impairments, this is how they navigate their entire digital lives.
Using a Mac or PC to force a shutdown
Let's say your buttons are jammed and your screen is shattered. You're basically stuck, right? Not quite. If you have a Lightning to USB-C cable (or a USB-C to USB-C cable, since we're talking about the iPhone 15 here), you can plug the phone into a computer.

On a Mac running macOS Catalina or later, open Finder. On a PC or older Mac, open iTunes.
Once the phone shows up in the sidebar, you have options. While there isn't a giant "Turn Off" button in the interface (which is an annoying oversight by Apple, if you ask me), putting the phone into Recovery Mode will often allow you to at least manage the device's state. To get it to shut down from here without a screen, you’re often looking at letting the computer interface "reset" the device's stuck state.
Why the iPhone 15 is different
The iPhone 15 series, including the Plus, Pro, and Pro Max, moved to the USB-C standard. This actually changed a few things regarding how the phone handles data and power handshakes with external accessories. If you use a USB-C mouse—yes, you can plug a standard computer mouse into an iPhone 15 now—a cursor will appear on the screen.
If your screen's visuals work but the touch doesn't, just plug in a mouse. You can use the mouse to slide the power-off bar just like you would with your finger. This is probably the most overlooked "hack" for modern iPhones. Any cheap USB-C dongle or a direct USB-C mouse will turn your phone into a mini-computer you can control without ever touching the glass.
Real-world limitations to keep in mind
It's worth noting that if your iPhone 15 is experiencing "ghost touching"—where the screen thinks it's being pressed even when it isn't—Voice Control and Siri might struggle. The phantom touches can sometimes cancel out the voice commands or physical button sequences. In those rare, nightmare scenarios, the only real solution is to let the battery die or take it to a technician who can disconnect the battery internally.
Also, keep in mind that a forced restart (the button dance mentioned earlier) is generally safe, but doing it constantly isn't great for the file system. It’s like pulling the plug on a desktop computer. Use it when you’re in a bind, but try to use the Siri "Power off" command as your primary method if you're just trying to be hands-free.

Actionable Next Steps
If you want to make sure you're never stuck in this position again, do these three things right now:
- Enable "Hey Siri": Go to Settings > Siri & Search and make sure "Listen for 'Hey Siri'" is toggled on. This ensures the power-off voice command is always available.
- Test the Button Sequence: Try the Volume Up, Volume Down, Hold Side Button sequence now. Get the rhythm down. It's faster than you think.
- Buy a USB-C to USB-A Adapter: Having a small dongle in your drawer allows you to plug in a computer mouse if your screen's touch capability ever fails, giving you full control over the UI to back up your data before shutting down.
Knowing how to turn off iPhone without touching screen iPhone 15 isn't just about convenience; it's about maintaining control over your device when the hardware fails you. Whether you use your voice, a mouse, or the physical bypass, you're never truly locked out.
