How to fix your Samsung Galaxy J5 that won’t charge [Troubleshooting Guide]

It is important that your Samsung Galaxy J5 will charge whenever you plug the charger in because without power, it’s just another expensive paperweight on your table. There are, however, times when a phone refuses to charge and while the charging process seems simple, it’s actually a very complicated process because both the firmware and hardware are involved.

Samsung Galaxy J5 battery charging

In this post, I will walk you through in troubleshooting your Galaxy J5 that won’t charge for some reason. It is imperative that we know why it isn’t charging so that we can formulate a method we can use to fix the problem. There are several steps you can do below to try to fix the not charging issue on your phone. This troubleshooting guide is based on how we technicians troubleshoot battery related issues so one of the steps may provide answers to your questions or even solve the problem.

Troubleshooting Galaxy J5 that won’t charge

The purpose of this troubleshooting guide is for us to know what the problem is and what needs to be done to fix it. While we don’t suggest procedures that can potentially damage the device, things can still happen while you’re troubleshooting so please proceed with care and follow the steps at your own risk. That said, here’s what you should do about your J5 that’s not charging:

Step 1: Pull the battery out and check physical condition of the battery

Your Galaxy J5 has a removable battery so you can actually try to check if it has developed some kind of lumps or if there’s something leaking. Just remove the back cover and pull the battery out. Place it on a level surface and try to flick it to see if it rotates freely because if that is the case, then it may have expanded and that might be the reason it won’t hold a charge anymore.

Defective batteries need to be replaced immediately as they pose danger not only to the device but also to the user. Batteries explode when overcharged, heated or short-circuited.

However, if one side is fine, try to do the same thing to the other side of the battery just to make sure nothing is wrong with it. As to the leakage, it’s very easy to spot as you only have to look for something wet on the edges. If there are no leaks nor lumps, it might not be a battery problem but we need to continue troubleshooting, so move on to the next step.

Step 2: Perform soft reset procedure and attempt to turn it on

After physically checking the battery of your phone, don’t place it back in immediately. Instead, press and hold the Power key for a minute to drain electricity that may have been stored in capacitors and other components. This way, the phone’s memory will be refreshed. This is what we call “soft reset.”

Once you’re finished with the soft reset, place the battery back in and secure it with the back cover. Make sure to place it correctly though. After which, try to turn the phone on and then connect the charger to see if it charges this time. If still no, then do the next step.

Step 3: Connect phone to computer or laptop

While your computer or laptop won’t give you the ideal current to charge your device at the same pace as with the original charger, the USB port still gives 5 volts of electricity which is enough to make your phone respond to it. We’re not actually trying to charge your phone by doing this, we’re simply trying to make sure the phone is detected so as to rule out the possibility that the cause of the problem is a broken cable.

If the phone doesn’t respond when connected to a computer, laptop or power bank, then try to check the connectors in the phone’s charging port. Try to look for lint, debris or bent pins that might be preventing it from properly conducting electricity. To get rid of lint and debris, you can give your phone a blast of compressed air but as to bent pins, you may try straightening them out but be very careful not to break them.

After doing all this and the problem still persists, move on to the next step.

Step 4: Use a different charger and USB cable

Try using a different charger and USB cable as the problem may be with them. This way, we can rule out the possibility that the problem is due to faulty accessories. You may use chargers of other phones and while they may not produce the same amperage as with the original charger, we’re simply trying to see if the device responds to other chargers because if so, then it’s obvious the problem is with the charger.

However, if the problem still persists after this, then switch back to using the original charger and continue with your troubleshooting.

Step 5: Try charging phone while in safe mode

Assuming there’s still battery left to power the phone, I suggest that at this point, you reboot your device in safe mode so as to rule out the possibility that the problem is caused by one or some of the third-party apps you downloaded from the Play Store or ones you may have sideloaded. This is how you boot your phone in safe mode:

  1. Turn your Galaxy J5 off.
  2. Press and hold both the Volume Down button and the Power key.
  3. When the Samsung logo displays, release the Power key but continue holding down the Volume Down button.
  4. Allow the phone to start up while holding down the Volume Down button; it may take a few seconds to complete.
  5. When the phone reaches the home screen and you can see “Safe mode” in the lower left corner of the screen, then it’s successful. Otherwise, repeat the steps from the top.

Alternatively, you can just follow these simple steps especially if you cannot bring your device to boot up in safe mode using the method above:

  1. Press the Power key to display power options on the screen.
  2. Touch and hold “Power off” option until “Restart to safe mode” prompt appears, then release.
  3. Tap Restart.
  4. The restart process may take up to 45 seconds to complete.
  5. Upon restart, Safe mode appears in the lower-left of the unlock/home screen.

While in this mode, try to charge your phone and if it still won’t charge, then it’s safe to say your third-party apps have nothing to do with it.

Step 6: Try charging phone while turned off

Assuming the phone doesn’t charge even in safe mode, then turn it off and re-plug the charger. Even if it’s turned off, it will still display the charging icon on the screen and light up the LED indicator at the top of the screen. If these things don’t show up, then the phone isn’t charging even if all its components are powered down. As far as basic troubleshooting is concerned, you’ve done everything a user can do to try to make the phone charge again. So, it’s time you sought professional assistance.

Step 7: Send the phone to a shop to be checked

You may consult a tech at a local shop or you can bring the device back to the store and have your provider’s or Samsung’s tech check it for you. I’m sure they can give answers to your questions and even fix the problem for you.

  1. seems Samsung has a problem with the charging system of the j5. i bought two of the same brands in a month and they all wont charge after just one month

  2. Hi,

    Thanks for the detailed information.
    Here is my problem:

    1) When phone is ON and plugged in then it indicates that its charging but its actually not.Battery drains out slowly like it does during normal operation.
    2) When phone if OFF and plugged in then it charges the phone normally.

    My phone is Samsung J5 2016.The charger has USB cable.
    Earlier,I have bought some random new USB cable after original was broken.
    Phone was charging properly (while its ON) with new USB cable until yesterday (I am using that USB cable since last 6 months).
    I tried another Samsung charger, but faced the same problem mentioned above.
    What could be the reason and solutions?

  3. My Samsung J5 recently had some sherry spilt over it. I took out the battery and wiped it clean, wiped other surfaces and left it open to dry overnight. It seemed to be ok when I put everything back together, apart from crackling sounds which disappeared after a few days. However, since then, the battery often refuses to charge. the screen reads :”Unable to charge. Battery temperature too low.” I’ve tried warming the battery in my hands and in the sun to no avail. I’ve tried leaving it switched off overnight – and on one occasion this worked. Today, I am frustrated…nothing seems to be working. And the crackles are back. Any insights?
