You’d think turning off a phone would be the easiest thing in the world. It used to be. You just held the button on the top or the side, waited for a second, and clicked "off." Done. But if you've recently upgraded from an older model like an iPhone 8 or a 7 to something newer—like the iPhone 15 or 16—you’ve probably realized that holding that side button doesn't actually shut the thing down. It just triggers Siri.
It's frustrating. Honestly, I’ve seen people standing in line at movies or airplanes frantically holding that side button while Siri chirps, "How can I help you?" loudly to the whole room.

Apple changed the hardware logic years ago, but the muscle memory persists. If you’re trying to power off an iPhone today, you’re basically dealing with a gesture-based system that requires a bit of coordination. It isn't just about silence; sometimes your phone is acting buggy, or the screen is ghost-touching, and you just need to kill the power to reset the logic board's state.
The Modern Handshake: Volume and Side Buttons
For every iPhone with Face ID (that’s everything from the iPhone X onwards, including the latest flagship models), the "Standard Shutdown" is a two-handed affair. You have to press and hold the Side Button (what we used to call the Sleep/Wake button) and either of the Volume Buttons at the exact same time.
Don't just tap them. You have to squeeze.
Hold them for about two seconds. You’ll feel a haptic "thump," and the power-off slider will appear at the top of the screen. Slide that to the right. The screen will go black, and you'll see a tiny spinning wheel for a moment while the iOS kernel shuts down processes.
It’s important to wait. Some people think the phone is off the moment the screen goes black, but if you’re doing this to troubleshoot a glitchy app or a GPS error, give it a full thirty seconds before you try to turn it back on. This ensures the volatile memory (RAM) is fully cleared. If you turn it back on too fast, you might just be reloading the same cached error.

Why did Apple make it harder?
It feels like a step backward, right? Why two buttons instead of one?
The answer is mostly about SOS features. Apple integrated a "Medical ID" and "Emergency SOS" feature into that same long-press menu. By requiring two buttons, they significantly reduce the chance of you accidentally turning off your phone in your pocket or triggering an emergency call to 911 while you’re sitting down. It’s a safety protocol disguised as a minor inconvenience.
Powering Off from the Software Settings
What happens if your buttons are broken? It’s a common issue, especially on older devices where the mechanical springs inside the buttons have finally given up the ghost. Or maybe you have a heavy-duty case that makes pressing the buttons a workout.
You can actually power off an iPhone without touching a single physical button.
Navigate to Settings, then tap on General. Scroll all the way to the bottom. I mean all the way—past the "Legal & Regulatory" stuff. You’ll see a blue text link that says Shut Down. Tap that, and the familiar "slide to power off" screen pops up.
This is also a great way to verify if a "frozen" phone is a hardware or software issue. If you can navigate the menus but the side buttons won't trigger the shutdown, you know you’ve got a hardware failure on your hands. If the Settings app itself is freezing, you’re looking at an iOS software bug.
The "Force Restart" When Everything is Stuck
Sometimes, the slider won't appear. The screen is unresponsive. Maybe you’re stuck on the Apple logo, or a specific app has locked up the entire UI. This is where most people panic.
You need the Force Restart.
This isn't a "soft" shutdown. It’s a hard break in the power cycle. It doesn't delete your data, but it does tell the hardware to ignore whatever the software is doing and just reboot. Here is the specific rhythm you need:
- Press and quickly release the Volume Up button.
- Press and quickly release the Volume Down button.
- Press and hold the Side Button.
Keep holding that side button. Do not let go when you see the power-off slider. If you let go then, you’ve failed. You have to keep holding it until the screen goes pitch black and the white Apple logo reappears. Only then should you release your grip.
I’ve had to do this on my own iPhone 14 Pro Max after a botched iOS update. It feels like it takes forever—usually about 10 to 15 seconds of holding—but it works. It’s the digital equivalent of pulling the plug out of the wall and plugging it back in.
Managing the iPhone 8 and SE Models
If you’re rocking an iPhone SE (2nd or 3rd Gen) or an iPhone 8, you’re in a weird middle ground. You have a Home button, but the internals are modern.
To power these off, you only need to hold the Side Button. You don't need the volume buttons. However, if you need to force restart them, you use the same "Up, Down, Hold Side" method mentioned above. It’s a bit confusing because the standard shutdown is "old school," but the emergency override is "new school."
Dealing with "Find My" after Powering Down
Here is something most people don't realize: your iPhone isn't truly "off" when you turn it off anymore.

Since iOS 15, Apple has used a low-power reserve mode that keeps the Find My network active. This allows your phone to be tracked by other nearby Apple devices even if the battery is dead or the phone is powered down. This is great for theft recovery, but if you are powering off for privacy reasons or because you’re heading into a sensitive environment, you need to know this.
When you bring up the "slide to power off" screen, you’ll see a small note under the slider that says "iPhone Findable After Power Off." If you tap that text, you can temporarily disable the Find My network for that specific power cycle. You'll have to enter your passcode to confirm. This is the only way to ensure the Bluetooth beacons and U1/U2 chips are actually dormant.
Troubleshooting Common Shutdown Issues
Sometimes the phone just refuses to die.
If you try to power off an iPhone and it immediately restarts itself, you likely have a "boot loop" or a faulty charging port. Check your Lightning or USB-C port for lint. Seriously. A tiny piece of pocket lint can bridge the pins in the charging port, making the phone think it’s being plugged into a power source, which automatically triggers a boot-up.
If the phone is stuck on the spinning wheel for more than five minutes, the shutdown process has crashed. This usually happens when a background process—like an iCloud backup or a photo indexing task—refuses to terminate. In this case, don't wait for the battery to die. Perform the Force Restart (Up, Down, Hold Side) to break the loop.
Actionable Steps for a Clean Reset
To ensure your iPhone stays healthy, don't just leave it on for months at a time. Electronic components benefit from a cold boot once in a while to clear out the system cache and reset the voltage regulators.
- Weekly Reboot: Aim to power off your iPhone for at least 60 seconds once a week. This clears out "ghost" processes that drain battery.
- Check Button Health: Periodically use the Settings > General > Shut Down method to ensure your software is responsive, even if your physical buttons feel fine.
- Update First: If your phone is frequently freezing and requiring a hard shutdown, check for an iOS update. Apple often releases "stability" patches specifically for kernel-level hangs that cause power issues.
- Clean the Port: Use a non-metallic toothpick to gently clear the charging port if the phone keeps restarting on its own.
Taking these steps ensures that when you actually need to shut down your device—whether for a flight, a meeting, or a troubleshoot—the system responds exactly the way it's supposed to.
