How To Fix Samsung Galaxy S9 Keeps Turning Off On Its Own
Problem: Hello! For 3 weeks now, I haven’t been able to use my S9. Completely randomly, on the 1st of January it turned off despite having 70% battery. I thought it was nothing so plugged it in charger. Charging logo showed up as usual and even went all the way up to 100%. I removed it from charge and went to turn it on…no response. Tried a couple more times even connected to power…still nothing. Searched your website on how to fix this issue read through steps, activated safe mode. It worked, or so i thought. After turning on in safe mode, it stayed about 50 seconds, turned off again (while being in charger). Tried again, but this time no response. Went back to your website, tried recovery mode. Initially didn’t work but once i plugged it in charger, it worked. pressed reboot system, turned on for 15 seconds, then turned back off. so back in recovery mode, wiped cache, made no difference. so I decided to factory reset the whole thing. It automatically turned on after reset and actually worked…for about 30 minutes. It turned off again. Went back on recovery mode pressed literally every option. The best i get is 2 minutes. I’ve been trying everything everyday for 3 weeks. Basically, the only response i get is recovery mode (and it has to be in charge, which appears to be working fine), and when i press reboot now, it works for max 2 minutes. (took it to nearest samsung repair shop, said it’s not battery or screen so they can’t do it with the warranty and im not willing to spend much on it as i’m hoping to get the s10. What do i do?
Solution: While this issue already appears to be caused by a faulty hardware component it is still best to eliminate any software related glitches that could be causing this problem. Listed below are the recommended troubleshooting steps for this particular issue.
Make sure that the phone battery is fully charged
The first thing you will have to do in this case is to charge the phone by following the steps listed below.
- Clean the charging port of the phone using a can of compressed air making sure that any dirt or debris stuck in it is removed.
- Fully charge the phone using its wall charger. If the phone does not charge then try using a different USB cord and wall charger.
Perform a soft reset
A soft reset which is usually done when a phone becomes unresponsive but is also recommended in this particular case as it will refresh the software.
- Press and hold the Power and Volume down key for up to 45 seconds.
- Wait as the device restarts.
Once the phone restarts check if the phone still turns off on its own.
Check if the issue occurs in Safe Mode
An app you downloaded in your phone could be causing this problem. To check if this is the case you will need to start the phone in Safe Mode since only the pre-installed apps are allowed to run in this mode.
- Turn the phone off.
- Press and hold the Power key past the model name screen appearing on the screen.
- When SAMSUNG appears on the screen, release the Power key.
- Immediately after releasing the Power key, press and hold the Volume down key.
- Continue to hold the Volume down key until the device finishes restarting.
- When Safe mode appears in the bottom left corner of the screen, release the Volume down key.
In case the issue does not occur in this mode then it’s likely that the problem is caused by an app you downloaded. Find out what app this is and uninstall it.
Wipe the cache partition of the phone
The phone system cached data is used to speed up the access to your phone apps. Sometimes this data can get corrupted which results in issues occuring on the device. To check if a corrupted cached data is causing the problem you will need to wipe the cache partition of the phone from the recovery mode.
- Turn off the phone.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key to highlight “wipe cache partition.”
- Press the Power key to select.
- Press the Volume down key to highlight “yes” and press the Power key to select.
- When the wipe cache partition is complete, “Reboot system now” is highlighted.
- Press the Power key to restart the device.
Check if the issue still occurs.
Perform a factory reset
One last troubleshooting step you should consider is a factory reset. This will revert your phone back to its original factory condition. Make sure to backup your phone data before doing the reset as it will be deleted in the process.
- Turn off the phone.
- Press and hold the Volume Up key and the Bixby key, then press and hold the Power key.
- When the green Android logo displays, release all keys (‘Installing system update’ will show for about 30 – 60 seconds before showing the Android system recovery menu options).
- Press the Volume down key several times to highlight ‘wipe data / factory reset’.
- Press Power button to select.
- Press the Volume down key until ‘Yes — delete all user data’ is highlighted.
- Press Power button to select and start the master reset.
- When the master reset is complete, ‘Reboot system now’ is highlighted.
- Press the Power key to restart the device.
Do not install any apps in your phone after the reset. Try to check first if the issue still occurs.
In case the issue persists even after performing the troubleshooting steps listed above then this is most likely caused by a faulty hardware component. The best thing to do right now is to have the phone repaired at a service center.
