In this post, I will address three of the most common power-related issues with the Samsung Galaxy S6 Edge (#GalaxyS6Edge), such as, not charging, won’t turn on and frequent restarts or reboots. Some of the cases we received were connected to the recent Android 6.0.1 #Marshmallow update while many occurred without apparent reason. That is why it is necessary to perform thorough troubleshooting procedures to know what the problem is, what causes it and what needs to be done to fix it.
Read on to learn more about these problems and how to deal with them should you encounter one in the future. Remember that we are tying to troubleshoot and there’s no guarantee of a fix. What we’re trying to accomplish here primarily is to know what the problem is so that if we can’t fix it, we’d be able to explain more clearly to the technician what the issue is. That way, it would be easier for him to fix it and much safer for the device.
Now, before we go any further, if you have other concerns with your phone, visit our troubleshooting page. It contains links to problems we’ve already given solutions before. Use our recommended fix or troubleshooting procedures. If they don’t work or if you need further assistance, contact us by completing this questionnaire.
Galaxy S6 Edge Not Charging Issue
The not charging issue is one of the most common with newer Galaxy models as it includes both the wired and wireless charging methods. However, based on reports, it’s the wired charging method that often fails and so we’ll have to tackle that in this article.
- Busted power adapter or charger
- Broken USB cable
- Bent pins on charger, cable and/or phone’s USB port
- System crash
- Battery issue
- General hardware problem
When troubleshooting, it’s always recommended you backup your data, files and everything you don’t want to lose if you can but if it’s impossible to do so, then always start troubleshooting with safe procedures. Now based on the possibilities I mentioned above, here’s what you need to do:
Step 1: Do the Forced Reboot procedure first
There’s a chance that it’s just a system crash especially if you can see the LED indicator blinking as if there are unread messages. So, the first thing you should do is forced reboot.
Press and hold the Volume Down and the Power keys together for 10 to 15 seconds to see if the phone reboots. If it does, problem solved! Otherwise, continue with your troubleshooting.
The Force Reboot procedure is equivalent to the battery pull in models with removable battery. As long as there’s enough battery left to power the components and it’s a system crash issue, the phone should reboot when both the Vol Down and Power keys are held for 10 seconds or more.
Step 2: Boot your device in safe mode and try charging it in that state
Aside from the system crash, there are also times with third-party apps interfere with the normal operation of the phone. You need to rule out this possibility first before continuing your troubleshooting and to do that, you need to boot the device in safe mode.
- Turn off your Galaxy S6 Edge.
- Press and hold the Power key.
- When ‘Samsung Galaxy S6 Edge’ appears, immediately release the Power key and then press and hold the Volume Down button.
- Continue holding the Volume Down button until the phone finishes the restart.
- When you see Safe Mode on the lower left corner of the screen, release the button.
While in safe mode, try to charge it and see if it charges fine. If not, then continue to the next step.
Step 3: Physical inspection of the charger, USB cable and the charging port
It’s a charging issue so it’s logical to suspect the charger or the power adapter as the culprit. The fact is, power adapters can easily get busted or its pins bent. What you need to do is look at the inside of the USB port to see if there are bent pins and if there’s none, place it near your nose to see if you can pickup some putrid scent from it. Burnt electronic components can easily be distinguished from the usual odor.
Also, try to run your finger from one end of the USB cable to the other to feel if there’s a break somewhere. You also need to inspect both ends for some bent pins. Since it’s difficult to straighten out its pins especially the smaller end, the best option you have is to buy a new one if such is the case.
In your phone, try to see if the USB port has some debris, lint or even dirt. You may use a brush to get rid of it if you can find some. You also have to be mindful if a pin or two is bent. You can actually straighten it out using a toothpick if it’s the case.
Step 4: Let the technician perform further troubleshooting and fix the problem for you
After doing all those things and your Galaxy S6 Edge still won’t charge, then the only option left for you to do is send the phone in for checkup and/or repair. It might be a battery or a major hardware fault. Since the device doesn’t have a removable or user-replaceable battery, you can’t just take it out and replace with a new one without voiding the warranty. So, you need a technician to do so.
Galaxy S6 Edge Won’t Turn On Issue
It is always necessary to know if your phone charges or not before troubleshooting issues like this one. If the phone charges, at least, you know already that some of the components as well as the firmware works. So, you can begin your troubleshooting by trying to turn the phone on and that’s exactly the purpose of the procedure I want you to follow.
Assuming your device charges and has battery power left, all you need to do are these:
Step 1: Try booting it in safe mode first. If it boots up just fine, then the problem isn’t the hardware but its firmware.
Step 2: Boot the device in recovery mode. Only do this if your phone didn’t boot up in safe mode. While all components are powered up in recover mode, the Android GUI isn’t loaded so if the problem was all with the firmware, it should boot up in recovery mode without a problem.
Better yet, try reading this as I explained this issue further in that post: How to fix Samsung Galaxy S6 Edge that won’t turn on [Troubleshooting Guide].
Galaxy S6 Edge Keeps Rebooting
Now, this issue is a bit more complicated than it seems. It can be caused by several factors and you need to find out what the culprit is before you will have to chance in fixing it. Random restarts usually don’t have a pattern especially if the it’s caused by a firmware or hardware problem.
- Some apps have gone rogue and keep crashing
- Caches and data got corrupted due to firmware update
- Corrupt firmware after interrupted update
- Faulty battery
- Hardware problem
Before anything else, if you’re the owner of the phone you’re trying to troubleshoot, you should know if it got updated or if the update was a failure. More often, firmware updates that got interrupted will resort to boot loop or frequent reboots due to missing or corrupted files. But if you really don’t have any clue what happened to your device, then try to follow these steps:
Step 1: Isolate the problem by booting the phone in safe mode
It should be the first thing you should do in cases like this. It will immediately divide the problem in half giving you an idea whether or not your downloaded or third-party apps have something to do with it.
If the problem was fixed in safe mode, then you need to find the app that’s causing it or try to remember what you were using when the phone rebooted by itself. You can then disable or uninstall it for good.
However, should the problem remain when all third-parties are disabled, then you should go after the firmware.
Step 2: Boot your phone in recovery mode and wipe the cache partition
The cache partition is where all system caches are stored. If you just updated your device to the latest Android version, Android 6.0.1 Marshmallow, there’s a chance that the cause of the restarts is some corrupt caches. That said, you need to wipe the cache partition so that the new system will forced to create new files that work best with it and here’s how you do it:
- Turn off the device.
- Press and hold the following three buttons at the same time: Volume Up key, Home key, and Power key.
- When the phone vibrates, release the Power key but continue to press and hold the Volume Up key and the Home key.
- When the Android System Recovery screen appears, release the Volume Up and Home keys.
- Press the Volume Down key to highlight ‘wipe cache partition.’
- 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.
Step 3: Try to backup your data and do the master reset via recovery mode
I understand your phone randomly reboots on its own so you can’t tell exactly if you can finish backing up your files and data but, at least, try it. Once finished, remove your Google account and disable screen locks (or choose None) so Factory Reset Protection (FRP) won’t be tripped when you do the master reset. But you only do this if wiping the cache partition didn’t work:
- Turn off your Samsung Galaxy S6 Edge.
- Press and hold the Volume Up, Home and Power keys together.
- When the device powers on and displays ‘Power on logo’, release all keys and the Android icon will appear on the screen.
- Wait until the Android Recovery Screen appears after about 30 seconds.
- Using the Volume Down key, highlight the option, ‘wipe data/factory reset’ and press the Power key to select it.
- Press the Vol Down button again until the option ‘Yes — delete all user data’ is highlighted and then press the Power key to select it.
- After the reset is complete, highlight ‘Reboot system now’ and hit the Power key to restart the phone.
Step 4: Send the phone in for repair
After the reset and the phone still restarts on its own, there are only three possibilities left: corrupt firmware, faulty battery and hardware problem.
If you are savvy enough, you can try flashing the firmware to your phone using Odin and a computer. But if you’re not comfortable doing it, you should seek help from a technician. As to the other possibilities, he should be doing further troubleshooting to determine the problem.
At this point, you’ve done what needs to be done on your phone as the owner.
