Turning off a smartphone used to be a simple matter of holding down a single button for a few seconds. However, as mobile technology has evolved, the hardware formerly known as the "Power Button" has been redefined as a "Side Key" or "Sleep/Wake Button." On most modern devices running the latest versions of iOS or Android, a long press on this button no longer brings up a power menu; instead, it summons digital assistants like Siri, Google Assistant, or Bixby.

This change has left many users frustrated, especially when they need to restart their device to clear a glitch or save battery life during a long trip. Whether you are using the latest flagship or an older model with a physical home button, this article provides every reliable method to shut down your device safely.

Why Modern Phones Do Not Turn Off With the Power Button Alone

The shift away from a dedicated power button is a strategic design choice by manufacturers like Apple, Samsung, and Google. By reassigning the long-press gesture to a digital assistant, companies ensure that their AI services are always just a second away. This transforms the button into a multifunctional tool: a single click locks the screen, a double click might open the camera or wallet, and a long press initiates a voice command.

While this adds functionality, it complicates the fundamental act of powering down. To turn off a modern phone, you now need to use specific button combinations or navigate through the software settings. Understanding these new "logic gates" is essential for troubleshooting and routine maintenance.

Every Way to Turn Off an iPhone Successfully

Apple led the transition toward button combinations with the release of the iPhone X, which removed the Home button and introduced Face ID. Since then, the shutdown process has remained consistent for newer models, though software updates like iOS 18 have introduced even more convenient ways to power down.

Powering Down iPhone Models With Face ID

If you own an iPhone X, 11, 12, 13, 14, 15, or the latest 16 series, the side button alone will only trigger Siri. To reach the power menu, you must use a dual-button gesture.

  1. Press and hold the Side button (on the right side) and either the Volume Up or Volume Down button (on the left side) simultaneously.
  2. Keep holding both buttons until the "slide to power off" slider appears at the top of the screen.
  3. Release the buttons and drag the slider to the right.
  4. The screen will go black, and the device will shut down completely after about 30 seconds.

In my testing across multiple generations of iPhones, using the Volume Up button is generally more ergonomic for right-handed users, as it mimics a pinching motion.

Turning Off Older iPhone Models With a Home Button

For those using an iPhone 8, iPhone SE (2nd or 3rd generation), or older models like the iPhone 7 and 6s, the process is closer to the traditional method. These devices do not require a combination of buttons because the Side or Top button is dedicated primarily to power functions.

  1. Press and hold the Side button (or the Top button on very old models like the iPhone 5) until the power off slider appears.
  2. Drag the slider to the right to shut down.

It is worth noting that even on these older models, if you have configured your settings to launch Siri via the side button, you may occasionally encounter a delay before the slider appears.

Using the Settings Menu for a Software Shutdown

If your physical buttons are difficult to press or if you have a protective case that makes them unresponsive, Apple provides a way to shut down your iPhone entirely through the software interface. This method works on every iPhone model regardless of the hardware version.

  1. Open the Settings app.
  2. Tap on General.
  3. Scroll all the way to the bottom of the list.
  4. Tap Shut Down.
  5. The "slide to power off" screen will appear. Drag the slider to the right.

This is often the safest way to turn off a phone if you suspect the hardware buttons are starting to fail or if you have motor control difficulties that make holding two buttons at once a challenge.

The New iOS 18 Control Center Method

With the release of iOS 18, Apple added a dedicated power icon directly into the Control Center, making it easier than ever to shut down without touching a physical button.

  1. Swipe down from the top-right corner of your screen to open the Control Center.
  2. In the top-right corner of the Control Center interface, you will see a small Power icon.
  3. Long-press or tap the Power icon.
  4. The system will prompt you with the power off slider. Drag it to finish.

This is a significant improvement for accessibility and a clear sign that physical buttons are becoming secondary to software-driven interactions.

Mastering Android Phone Shutdown Methods Across All Brands

The Android ecosystem is diverse, and while many manufacturers follow a similar logic, brands like Samsung and Google have their own unique implementations. Most modern Android phones now default to launching Google Assistant or a proprietary AI when the power button is held.

How to Turn Off a Samsung Galaxy Device

Samsung’s "Side Key" is highly customizable. On devices like the Galaxy S24 or Galaxy Z Fold 6, holding the side key launches Bixby by default. Samsung users have three primary ways to power down.

The Button Combination Method:

  1. Press and hold the Side key and the Volume Down button simultaneously for about three seconds.
  2. The Power Menu will appear on the screen with options for "Power off," "Restart," and "Emergency call."
  3. Tap Power off, then tap it again to confirm.

The Quick Settings Method:

  1. Swipe down from the top of the screen once to see notifications, and a second time to expand the Quick Settings panel.
  2. Look for the Power icon near the top-right or bottom-right of the screen (depending on the One UI version).
  3. Tap the icon to bring up the power menu.

Remapping the Side Key: If you hate that the button launches Bixby, you can change it back to a traditional power button. Go to Settings > Advanced features > Side key. Under the "Press and hold" section, select Power off menu instead of "Wake Bixby." After this change, a simple long-press of the side button will act as it did in the past.

Powering Down Google Pixel Phones

Google Pixel devices (from the Pixel 6 onwards) also use a combination of buttons to prevent accidental shutdowns and to prioritize Google Assistant.

  1. Press and hold the Power button and the Volume Up button at the same time.
  2. Wait for the power menu to appear.
  3. Tap Power off.

For older Pixel models (Pixel 5 and earlier), simply holding the power button for a few seconds is usually enough to bring up the menu. Like Samsung, Google also includes a power shortcut in the Quick Settings panel, accessible by swiping down twice from the top of the screen.

Methods for Motorola and Other Major Android Brands

Motorola, OnePlus, and Xiaomi devices often utilize the Power + Volume Up combination. However, some Motorola models still allow a long press (approx. 5 seconds) on the power button to trigger the menu. If your Motorola device brings up Google Assistant instead, stick to the dual-button method or use the software icon in the notification shade.

In my experience with various Android skins, if you are unsure, the Power + Volume Up shortcut is the most universal "safe bet" across the platform.

Using the Android Quick Settings Panel

For any Android phone running Android 12 or newer, the Quick Settings panel is the most reliable software method.

  1. Swipe down from the top of the screen with two fingers (or swipe down twice with one finger).
  2. Locate the Power icon (a circle with a vertical line).
  3. Tap the icon and select Power off.

How to Turn Off Your Phone Using Voice Commands

If your hands are busy or you cannot reach the buttons, you can use your phone's built-in digital assistant to perform a shutdown. This feature was previously restricted for security reasons but is now available on most modern systems.

On iPhone (Siri):

  1. Say, "Hey Siri, turn off my phone."
  2. Siri will ask, "Just to confirm, you want to power off this device?"
  3. Say "Yes" or tap the "Power Off" button that appears on the screen.

On Android (Google Assistant):

  1. Say, "Hey Google, turn off my phone" or "Power off."
  2. In many cases, the Assistant will display the power menu on the screen, requiring you to tap the final "Power off" button for security confirmation.

This is particularly useful for users with limited mobility or those who use their phones in a hands-free environment like a car mount.

What to Do When Your Phone Is Frozen or Unresponsive

Sometimes, a software bug causes the screen to freeze, making it impossible to use the "slide to power off" or tap any on-screen icons. In these cases, you must perform a "Force Restart" or a "Hard Reset." This does not erase your data; it simply cuts the power to the processor to force a reboot.

Force Restarting an iPhone (8 and Later)

This requires a specific sequence that must be performed quickly:

  1. Press and quickly release the Volume Up button.
  2. Press and quickly release the Volume Down button.
  3. Press and hold the Side button.
  4. Important: Do not release the side button when you see the power off slider. Continue holding it until the screen goes black and the Apple logo appears.

Force Restarting an Android Phone

Most Android devices use a simpler but longer duration press:

  1. Press and hold the Power button and the Volume Down button simultaneously.
  2. Hold them for 15 to 20 seconds.
  3. The device will eventually vibrate, the screen will go black, and it will begin to reboot.

On some specific models (like older Pixels or certain Motorola phones), you may only need to hold the Power button for a full 30 seconds to force a shutdown.

Turning Off a Phone With a Broken Power Button

A damaged power button can make turning off a phone feel impossible, but both major operating systems have built-in accessibility tools to handle this.

For iPhone (AssistiveTouch):

  1. Go to Settings > Accessibility > Touch > AssistiveTouch and toggle it On.
  2. A floating gray circle will appear on your screen. Tap it.
  3. Go to Device > More > Restart (or you can long-press the "Lock Screen" icon within the menu to trigger the power off slider).

For Android (Accessibility Menu):

  1. Go to Settings > Accessibility > Accessibility Menu.
  2. Turn on the Accessibility Menu shortcut.
  3. A small icon (usually a person shape or a green dot) will appear at the bottom of your screen.
  4. Tap it and select Power. This will bring up the shutdown menu without needing any physical buttons.

Summary

In today's mobile landscape, turning off your phone requires knowing the right combination of hardware and software. For iPhones, the Side Button + Volume combo is the standard, while Android users should look toward the Power + Volume Up combo or the Quick Settings panel. If your device is frozen, a long-held force restart is your best tool. By mastering these methods, you ensure that you are always in control of your device, whether you are trying to save battery, troubleshoot an app, or simply enjoy some much-needed "do not disturb" time.

FAQ

Why does my phone vibrate but not turn off when I hold the buttons?

This usually happens if you are holding the wrong combination or not holding them long enough. On many Android phones, holding Power + Volume Down for a short period takes a screenshot. Ensure you are holding the buttons for at least 3 to 5 seconds to see the menu, or up to 20 seconds for a forced restart.

Can I schedule my phone to turn off and on automatically?

Many Android phones (such as those from Samsung and Xiaomi) have a feature called "Scheduled Power On/Off" located in the Settings menu under "Battery" or "Additional Settings." Apple does not currently offer a native "Scheduled Power Off" feature, although you can use the "Focus" and "Sleep" modes to simulate a similar quiet period.

Will turning off my phone delete my open tabs or apps?

No. Turning off your phone saves the current state of your system. When you turn it back on, your browser tabs and most apps will remain where you left them, although some apps may need to refresh their data.

Is it better to "Restart" or "Power Off"?

If you are troubleshooting a minor bug, a "Restart" is faster. If you plan to leave your phone unused for several hours or days, a full "Power Off" is better for preserving battery health and preventing deep discharge.

My phone won't turn back on after I shut it down. What should I do?

First, plug it into a known working charger for at least 30 minutes. Sometimes the battery was lower than you realized when you shut it down. If it still won't turn on, try the "Force Restart" steps mentioned above while the device is plugged in.
