How to turn off Android phone can vary more than expected because different brands assign different actions to the Power or Side button. On some devices, a long press opens the shutdown menu, while others launch Bixby, Google Assistant, or require a button combination instead.
The good news is that there is usually more than one way to power the device down, including on-screen options when the physical button is inconvenient or unresponsive. Read on to find the shutdown method that matches your phone and what to try when the usual button press does not work.
1. How to Turn Off Android Phone: The Main Ways
Three methods cover how to turn off Android phone. Which one applies depends on the phone model and Android version.
Open the Power Menu With the Phone’s Buttons
The first way on how to turn off Android phone is to open the power menu with the phone’s buttons. On many Android phones, pressing and holding the Power button opens the power menu. However, the exact button combination varies by brand and model.
On some newer devices, the Power button may launch a voice assistant instead, requiring another button combination or a settings change.
A menu appears with options for Power Off, Restart, and sometimes Emergency or Airplane Mode. Tap Power Off, and the phone shuts down.
Use the Quick Settings Power Icon
Swipe down from the top of the screen twice to expand the full Quick Settings panel.
On many Android versions, a power icon or a device controls icon appears in the bottom corner of the Quick Settings panel. Tapping it opens the power menu with the same Power Off and Restart options available through the button method.
On some Android phones, including many Samsung Galaxy models, the expanded Quick Settings panel includes a Power icon that opens the shutdown menu. If your phone does not show one, use another method supported by your device.
Use the Accessibility Menu Without Physical Buttons
Some Android manufacturers include an on-screen power control in Quick Settings or another system menu, allowing you to shut down the phone without using the physical Power button.
Android’s Accessibility Menu can help with many hardware-button functions, but available controls vary by device and Android version. Check your phone’s accessibility and Quick Settings options to see whether a power control is provided.
2. Samsung Galaxy Phones Use the Side Key Differently
Knowing how to turn off a Samsung phone, or more precisely how to turn off Samsung phone models on recent One UI, requires understanding how Samsung has configured the Side Key. The default behavior changed with Samsung’s One UI updates and differs from stock Android.
Hold the Side Key and Volume Down Button
If you are wondering how to turn off Android phone, you can hold the Side Key and Volume Down Button.
On many newer Samsung Galaxy phones, pressing and holding the Side button may launch Bixby instead of opening the power menu. To shut down the phone, press and hold the Side button and Volume Down button together for a few seconds, then tap Power off.
Change the Side Key Action to the Power Menu
Samsung allows reassigning what a long press of the Side Key does. Go to Settings, Advanced Features, Side Key. Under Press and Hold, change the setting from Wake Bixby to Power Off Menu.
Once changed, a long press of the Side Key alone opens the power menu, which is the behavior most users expect. This setting persists across reboots and is the simplest long-term fix for users who find the Bixby default disruptive.
On Older Galaxy Models With a Single Power Button
Older Galaxy models such as the Galaxy S8, S9, and Note9 have a dedicated Power button separate from the Bixby key. Pressing and holding the Power button normally opens the shutdown menu.
The power menu appears with Power Off and Restart. The button location varies by model: on S8 and S9 it is on the right edge, on Note models it is also on the right side below the volume buttons.
3. When the Power Button Doesn’t Work
After knowing how to turn off Android phone, you should know when the power button doesn’t work. A physically damaged or unresponsive power button does not prevent a phone from being turned off, since Android provides software alternatives for every hardware button function.
- Use the Accessibility Menu. Enable it through Settings, Accessibility, Accessibility Menu as described above. The floating button provides full power menu access without touching the physical button.
- Use Quick Settings. The power icon in the expanded Quick Settings panel shuts down the phone without the physical button.
- Schedule a power-off. Some Android manufacturers include scheduled power or restart features, but availability varies widely by brand, model, and software version. Check the Battery, Device Care, or scheduled power settings on your phone rather than assuming the option is available.
- Connect to a computer and use ADB. Android Debug Bridge allows sending a shutdown command from a computer via USB. Advanced users can use ADB from an authorized computer with USB debugging already enabled. The command adb shell reboot -p powers off many Android devices, but it will not help if USB debugging was never enabled or the computer has not been authorized.
- Force a shutdown with a hardware key combination. If the phone is frozen, a long press or hardware-button combination can often force it to restart. The exact combination varies by manufacturer, so check the device’s support instructions. A forced restart is not the same as powering the phone off and leaving it off.

4. FAQs
Why Does Holding the Power Button Open Bixby or Google Assistant Instead?
Some newer Samsung Galaxy phones use a long Side button press for Bixby, while Pixel 6 and later use a long Power button press for Google Assistant by default. On supported devices, you can usually change this behavior in the button or gesture settings.
What Is the Difference Between Turning Off and Restarting My Phone?
Turning off cuts power to the phone completely, clearing the active memory and stopping all running processes. Restarting performs the same shutdown but immediately initiates a boot sequence afterward.
Can I Turn Off My Phone Without Using Any Buttons?
Often, yes. Some Android phones provide an on-screen Power icon in Quick Settings or another system menu. Availability varies by manufacturer, so check your phone’s Quick Settings and accessibility options.
Is It Bad to Leave My Phone Off for a Long Time?
No, with one caveat. Leaving an Android phone off is fine for days or weeks. For longer storage, a battery level between 40 and 60 percent is recommended before shutting down, since lithium-ion batteries degrade faster when stored at very low or very high charge levels.
Conclusion
Turning off a phone should be simple, but the exact method can change with the brand, model, and button settings. Once you know how your device handles the Power or Side button, the process becomes much easier to repeat without guessing.
Learning how to turn off Android phone also helps when the usual button behavior changes or the hardware stops responding. Start with the standard power menu, then use the on-screen controls or model-specific alternatives available on your device when needed.
