Power-related issues in android devices is one of the most common problems that android users were experiencing for the past several years. As a matter of fact, there are several users were complaining about this issue wherein their device won't power on after the update without apparent reason. On the other hand, problems like this is somehow caused by corrupt files and data or the firmware itself was corrupted during the process and resulted your phone not to turned on.

So, in this post, we will try to consider all possible causes why this issue is happening through performing the step by step procedure on your phone. If you are a Galaxy S4 users and you haven't experience this issue, then, we suggest you to continue reading this post for it might help you in the future. That being said, here are the methods that you should do:

Step 1: Verify if the battery is faulty and do a soft reset

In troubleshooting this problem, it is imperative that you should check if the battery is faulty or not. Because if it is, then that would be the reason that your phone refused to power on. In addition, if the battery is totally drained that would be another factor that your device is unable to turn on. So, in this instance, we will try to charge your phone to see if your S4 is capable to charge and the charging icon will appear on the screen.

While it is connected to the charger let it charge for at least 20 minutes regardless the icon will appear or not. When the time elapse and the icon appears try to power on your device to see if it is capable of doing so. If it is still unresponsive, disconnect it from the charger and remove the battery and press the Power key for 10 seconds to discharge all stored electricity in the hardware components. After you do so, place it back the battery and reconnect it to the charger and turned it on.

However, after you do all of that and nothing is happening on your phone, then proceed to the next step.

Step 2: Boot it in Safe Mode

In this method, we have to eliminate the suspicion that incompatible apps causing the issue by restarting it in safe mode. Through this environment all third-party apps will be eliminated temporarily and only the pre-installed ones will be running in the system. So, after booting your phone in this mode and the issue is not happening, then obviously there's an app you need to find and uninstall to get rid the issue. This is how you boot it in safe mode:

1. Turn off your Galaxy S4.
2. When the Galaxy S4 appears on the screen, release the button and immediately press and hold the Volume Down key.
3. Continue holding it until the phone finished restarting.
4. If the phone successfully rebooted, you will see Safe mode in the bottom left corner of the screen. You may release the Volume Down key now.

However, safe mode is not helping the issue proceed to the next step.

Step 3: Wipe the System Cache Partition

Since, the system has been updated there is a chance that the system files and data were ruined during the process. These files and data are stored in the cache partition and responsible for the device to perform normally. Although there is no assurance that the issue will be fixed after performing the method but there were reports from other users saying that after doing it their device is already performing normally. So, by performing this method all files and data saved in the partition will be deleted and newer ones will be replaced.  Here's how:

1. Press and hold the Volume Up, Home and Power buttons at the same time.
2. When the phone vibrates, release the Power key but continue to press and hold the Volume Up and Home keys.
3. When the Android System Recovery appears, release both remaining buttons.
4. Use the Volume Down key to highlight 'wipe cache partition' option and press the Power key select it.
5. The phone will automatically restart once wiping is finished.

After clearing all system files and data try to Power on you device and see if it will. If the problem still persists you can jump over to the next method.

Step 4: Perform Master reset

If all procedures you performed failed to resolve the issue, then, the last option that you can do is to do a reset. Meaning, you have to delete files and data saved on your phone including: contacts, photos, music, videos and etc. So, before you have to follow the steps be sure to create first a backup and so that you can restore easily when the issue is fixed. But the good thing is, if this just a software problem, then this procedure will surely resolve it. 

1. Turn off your Galaxy S4.
2. Press and hold the Volume Up, Home and Power buttons at the same time.
3. Release the Power button when the phone vibrates but continue to press and hold the Volume Up and Home keys.
4. When the Android System recovery screen appears, release both the Home and Volume Up keys.
5. Using the Volume Down key highlight 'wipe data/ factory reset.'
6. Press the Power button to select it.
7. Using the Volume Down button again, highlight 'delete all user data.'
8. Press the Power key to select it.
9. Once the reset is complete, choose 'Reboot system now.'
10. Press the Power button to restart the device.

After you do the reset and your phone turned on, then obviously a software problem triggered it. But if reset is unable to fix the problem you can immediately bring your phone to the tech for your Galaxy S4 might have a hardware issue.
