How to fix Samsung Galaxy S6 that’s not charging [Troubleshooting Guide]

We received several email messages from our readers who were seeking assistance because their new Samsung Galaxy S6 won’t charge. Some said the screen just went dark and when plugged in, it won’t respond and won’t show the usual charging signs.

The most common misconception about not charging issues is that people used to think it’s all hardware and/or accessory issue like it’s a problem with the charger, battery or the phone itself. The fact is a firmware glitch may also cause it. There were a lot of owners who reported having experienced this problem only to find out that their device froze wouldn’t respond.

But then, of course, proper troubleshooting should be done to determine the cause. Once you know what the culprit is, that’s the time you find ways to address the problem.

In this post, I will guide you on how to troubleshoot your Samsung Galaxy S6 that won’t charge. This is the very same procedure we technicians follow if a customer walks into the shop bringing a phone that has this kind of problem. The steps are easy and, actually, basic but they’re effective in determining what the culprit is. However, there’s no guarantee you could fix the problem after reading this post especially if the problem is hardware-related. But, at least, you would have an idea so you could properly explain the problem to a technician.

For those who have different issues, visit our Samsung Galaxy S6 Troubleshooting page as we’ve listed all problems we addressed since this phone was released. Try the solutions we provided first and if they didn’t work for you, then tell us about your problem. Just fill up this form properly and we will help you find a solution. Remember, the more information you provide, the more accurate our solutions are. So, choose the proper options in the drop-downs and provide as much details as possible.

Step 1: Make sure Galaxy S6 didn’t just freeze

Unlike the older Galaxy devices, the new Galaxy S6 didn’t come with removable battery. So, if it froze for some reason, you couldn’t do the “battery pull” trick to address the issue but Samsung added a new feature to allow users to hard reboot their phones if they became unresponsive. In fact, if you’ve been observant enough or was paying attention when you first booted your phone, you should know by now what needs to be done. But for the benefit of those who weren’t able to read the instruction, here it is: “If your device is unresponsive, press and hold the Power key and the Volume down key simultaneously for more than 7 seconds to restart it.

That’s right! That’s what you need to do to rule out the possibility that the reason why your phone doesn’t charge is because it’s frozen. If it didn’t reboot the first time, do it 2 to 3 times just to make sure. However, if the screen remained black and won’t charge after several attempts to reboot, then it’s time you performed the basic troubleshooting.

Step 2: Troubleshoot the charger

The easiest way to know if the charger is the problem is to use a different one. If you can borrow from a friend who has the same device as yours, that would be better. I discourage you to buy a new charger at this point because there’s no guarantee it’s the problem.

If you have a non-Samsung charger that gives out 1.5A to 2A current, try using it just to find out if the phone would respond to it. If it didn’t, then proceed to the next step.

Step 3: Troubleshoot the USB cable

The cable is very important because it bridges the charger and the phone; without it, it’s impossible for the charger to push electric current into the phone. So, after ruling out the possibility of a charger issue, you should rule out this possibility next.

One way to know if the USB cable is working or not is to use a different one and plug it into the charger (and the other end into the utility port of the phone) and see if the device would respond. You may also plug it in to a computer.

The very purpose of this procedure is to make the phone respond once plugged in but if it didn’t no matter what you do, then it’s time to proceed to the next step.

Step 4: See if the USB or utility port is loose

Loose connection creates trouble most of the time. The same is true if the cable doesn’t snap right in to the USB port on your phone. If it’s some kind of loose, wiggling it to make contact may allow the phone to charge. However, if the problem is internal (like when the USB port itself is not properly connected to the board), then there’s not much you can do about it. You couldn’t even open the phone to inspect it because removing a screw by yourself will automatically void the warranty.

Step 5: Send the phone for repair

If all else fails, then you need a technician to help you fix the problem. You may bring the phone to the store where you bought it or call Samsung. It is necessary to make sure you can claim warranty in case the device needs to be repaired. It is also one way of saving yourself from all the hassles in troubleshooting a problem you don’t know.

While I believe in the power of troubleshooting, I think a new phone should work perfectly. If it doesn’t, then send it in for repair or have it replaced as soon as possible. After all, you paid for a device you can use and not for a phone that will bug you every minute of every day.

  1. Thanks for this!! Holding the Power Button and Down Button simultaneously has done the trick and my phone is once again charging! Why it wouldn’t charge is still a mystery as this issue came out of the blue… but at least for now we’re back on the road!! Ooooooooor perhaps we should say…. Phone! Thanks again! 😉

  2. Your help is invaluable – it needed to be rebooted & hadn’t noted the “press and hold the Power key and the Volume down key simultaneously for more than 7 seconds to restart it.”

    It worked – thanks so much!

  3. Hi there Harold Hisona, thank you for taking the time to publish this information. I am going through the process right now to see if perhaps my Samsung Galaxy S6 Active was being charged by a faulty charger of mine. I am not certain at all at this point, all I know is I woke early to find my phone on the charger and only at 19%.

    I am using a different charger right now and it went from 19% to 21% in about 2 minutes (which to me is not especially fast). We live with our phones now; unlike the generations before us. So fingers crossed that it is a faulty charger cord. I suppose I will know soon enough but meanwhile, I am saving this article to my bookmarks so I can go back and refer to it later if necessary. Kindly, Kim F

  4. damn firmware update is’s all because of it.
    Thing helped me – to turn it off, reconnect charger(may be few times) wait until charge indicator appears and after it turn it on

  5. If your phone isn’t charging plugged in, try this…unplug charger from charger port
    consecutively about 5 times, then leave plugged in. Worked for ours.

  6. Well, that was rather unhelpful. I was hoping for information on troubleshooting the firmware, I’d really rather not have to take my phone in. Would you be able to provide that as well?

  7. Thank you so much. Step 1 was simple and resolved my issue. Thanks for saving me a trip to the store and avoiding the hassle there.

  8. Solution! Use something small, like as a toothpick, to ‘lever up’ the little tab inside the USB port. (And maybe clean out some lint while you’re in there).

    This worked like a charm for me after trying everything else:
    -multiple cables, adapters, wall sockets
    -restart, cleared cache, booted in safe mode, soft reset, factory reset
    But in the end the cable tip was simply not making good contact with the phone USB port.

    It all started with a weird VR glitch flashing on and off my screen. But that was a symptom, not a cause.

  9. You could lend a wireless charger from your friend or buy one (not every wireless charger will work however).
