The importance of turning off your phone properly
Unlike putting your S25 in sleep mode, a full power down gives the system a chance to close background services, clear memory, and prepare for the next usage cycle.
This helps optimize battery life and performance. Powering off fully periodically also helps clear up any small software issues that can build up over time.
How to properly turn off your Samsung Galaxy S25
There are a few easy ways to power down your S25 phone fully:
Turn it off using the side key
Turning off your Samsung Galaxy S25 using the Side-Key button is simple:
- Press or hold the Side Key; it should function as a power button and bring up the power menu. You can customize it to best fit how you use your phone.
- Tap “Power off” on the screen.
- Tap “Power off” again to confirm.
The phone will power down completely. The screen will go black when the process is finished.
If your phone is unresponsive, you can force reset by pressing and holding the Power and Volume Down buttons together for over 7 seconds until the phone shuts off. However, avoid doing this unless necessary.
Turn it off using the widget
Here are some steps for turning off your Samsung S25 using the power widget:
- Swipe down from the top of the screen to open the notification shade.
- Swipe down again to expand the quick settings panel.
- Look for the Power Off tile and tap it. This should bring up a pop-up confirmation menu.
- Tap the Power Off button in this menu to turn off your phone.
The power widget provides a quicker way to power down your phone without having to navigate through menus.
Here are the steps to turn off your Samsung Galaxy S25 using Bixby voice commands:
- Wake up Bixby by pressing and holding the Bixby button on the side of the phone or saying “Hi Bixby.”.
- Once Bixby is activated, say, “Bixby, turn off this phone” or “Bixby, power off.“.
- Bixby will respond and confirm the request to power off the phone.
- The phone screen will turn off, and the device will power down completely.
Additional tips for optimizing battery life
In addition to periodic complete power downs, reducing screen brightness, closing unused apps, and enabling power-saving modes can help extend battery life. Avoid exposing your Galaxy S25 to extreme hot or cold temperatures.
Properly turning off your Samsung Galaxy S25 periodically is a simple way to keep your device running smoothly. Just press and hold the side key, tap the power control widget, or use Bixby voice commands to power down your phone fully. This helps optimize system performance and battery life.
