Are you stuck with a Galaxy S21 that won’t turn on due to a faulty power button? Don’t worry, you’re not alone! In this comprehensive guide, we’ll explore the various methods to turn on your Galaxy S21 without the power button, helping you breathe new life into your Android device.
Understanding The Power Button Mechanism
Before we dive into the solutions, it’s essential to understand how the power button mechanism works on your Galaxy S21. The power button, also known as the on/off button or sleep/wake button, is a mechanical switch that triggers the device to turn on or off. When you press the power button, it sends an electrical signal to the phone’s motherboard, which then powers up or shuts down the device.
However, if the power button becomes faulty or damaged, it can prevent your Galaxy S21 from turning on, even if the battery is fully charged. In such cases, you’ll need to find alternative methods to turn on your device.
Method 1: Using The Volume Down Button And Plugging In The Charger
One of the most common methods to turn on a Galaxy S21 without the power button is by using the volume down button and plugging in the charger. Here’s how:
Step 1: Plug in your Galaxy S21 to a wall charger or a USB port on your computer.
Step 2: Press and hold the Volume Down button located on the left side of your device.
Step 3: Hold the Volume Down button for at least 10 seconds or until you see the Samsung logo on the screen.
Step 4: Release the Volume Down button when the device boots up.
This method works because the Galaxy S21’s firmware is designed to detect the charging connection and automatically turn on the device when the charger is plugged in. By holding the Volume Down button, you’re essentially overriding the faulty power button and telling the device to turn on.
Method 2: Using Android Debug Bridge (ADB)
If the above method doesn’t work, you can try using Android Debug Bridge (ADB) to turn on your Galaxy S21. ADB is a command-line tool that allows developers to communicate with Android devices from a computer. Here’s how to use ADB to turn on your device:
Step 1: Enable USB Debugging on your Galaxy S21 by going to Settings > Developer options > USB debugging.
Step 2: Connect your Galaxy S21 to your computer using a USB cable.
Step 3: Open a command prompt or terminal window on your computer and navigate to the platform-tools directory where ADB is installed.
Step 4: Type the following command: adb reboot
Step 5: Press Enter to execute the command.
The adb reboot command will force your Galaxy S21 to restart, potentially turning it on even without a functioning power button.
Method 3: Using A Jig Or A Bootloader Key
A jig or a bootloader key is a specialized tool designed to bypass the power button and boot up your device. These tools are typically used by phone repair technicians or enthusiasts who need to access a device’s bootloader or recovery mode.
Step 1: Obtain a jig or a bootloader key specifically designed for your Galaxy S21 model.
Step 2: Connect the jig or bootloader key to your device’s USB port.
Step 3: The jig or bootloader key will simulate the power button press, allowing your device to turn on.
Please note that using a jig or bootloader key may require some technical expertise and should be done with caution to avoid damaging your device.
Method 4: Visiting A Samsung Authorized Service Center
If none of the above methods work, it’s possible that the issue lies with the power button’s mechanical failure or a more serious internal problem. In such cases, it’s recommended to visit a Samsung Authorized Service Center or a reputable phone repair shop.
A professional technician can diagnose the issue and provide a suitable solution, which may include repairing or replacing the power button, or performing a more extensive repair.
Preventing Power Button Failure
To avoid power button failures in the future, here are some preventive measures you can take:
Handle with care: Be gentle when handling your Galaxy S21, avoiding excessive pressure or squeezing that could damage the power button.
Cleanliness is key: Regularly clean your device, paying attention to the power button and surrounding areas, to prevent dirt and debris buildup.
Update your firmware: Ensure your Galaxy S21 is running the latest firmware, as Samsung often releases updates that address power button-related issues.
Use a case or cover: Protect your device with a case or cover that provides adequate protection for the power button.
By following these tips, you can minimize the risk of power button failure and extend the lifespan of your Galaxy S21.
Conclusion
Turning on a Galaxy S21 without the power button can be challenging, but with the right techniques and tools, it’s possible to overcome this issue. By understanding the power button mechanism and using alternative methods like the Volume Down button, ADB, or a jig/bootloader key, you can breathe new life into your device. Remember to take preventive measures to avoid power button failure in the future, and if all else fails, seek the assistance of a professional technician.

What If My Galaxy S21 Power Button Is Broken?
If your Galaxy S21 power button is broken, don’t panic. You can still turn on your device without it. There are a few methods you can try to turn on your Galaxy S21 without the power button. You can use the volume down and plug-in method, the USB-C method, or the Android Debug Bridge (ADB) method. Each of these methods has its own steps, but they can all help you turn on your device in the event that your power button is broken.
It’s important to note that if your power button is broken, you may need to have it repaired or replaced. If you’re not comfortable attempting to fix it yourself, you can contact the manufacturer or a professional repair service to get it fixed. In the meantime, these methods can help you turn on your device and continue using it until you can get the power button repaired.
Can I Use The Volume Down And Plug-in Method With Any Galaxy S21 Model?
The volume down and plug-in method is a common way to turn on a Galaxy S21 without the power button. To try this method, press and hold the volume down button on the left side of your device, then plug in your charger or a USB-C cable. Hold the volume down button for at least 10 seconds to see if your device turns on. This method should work for most Galaxy S21 models, including the Galaxy S21, Galaxy S21+, and Galaxy S21 Ultra.
Keep in mind that this method may not work for all devices, especially if the power button is broken due to a software issue rather than a hardware problem. If this method doesn’t work, you can try one of the other methods mentioned earlier. It’s also a good idea to back up your data regularly to prevent any potential losses in case your device becomes unresponsive.
What Is The USB-C Method, And How Does It Work?
The USB-C method is another way to turn on your Galaxy S21 without the power button. To try this method, plug a USB-C cable into your device and the other end into a computer or a wall charger. Then, press and hold the volume down button on the left side of your device for at least 10 seconds. If your device turns on, you’ll see the Samsung logo on the screen.
