Why does your Samsung Galaxy J7 won’t charge and how to fix it? [Troubleshooting Guide]

When the phone doesn’t charge people would usually jump into a conclusion that the battery might have been damaged and thus no longer able to charge up. While this may be true in some cases, often times the main problem is on the software. Aside from a bad battery, what other things can cause your device to not charge as intended? Let’s find out then.

What to do when your Galaxy J7 doesn’t charge?

As mentioned earlier, it’s not always the battery’s fault. Most of the time, it is a software glitch like rogue apps and corrupt files that prevent the charging system from doing its task. Every component on your device is programmed to carry out certain functions like the camera app responsible to work with the physical camera. The only difference is that the charging system is not visible nor accessible by end-users. In short, it works without you even knowing. You notice that when your battery percentage drops down to 10 percent or lower, you’ll be prompted with an alert message saying that your battery is getting low and so you need to plug your device into the charger. That is part of the charging system’s job. When you connect your device to the charger, you’ll see the charging indicator or a progress bar showing the current power level your device has until it finally gets full. The charging system is behind that too. All these are part of the charging system’s programmed routine. If something wrong happens like when the charging system gets bugged, corrupted, or affected by some malware, that is when charging problems begin to manifest. To get things back to normal with charging, you need to deal with whatever triggers the charging system to glitch. And that’s when you need to troubleshoot the software.

If the problem persists after troubleshooting the software, then most likely the hardware is to blame. This is when you need to scrutinize the hardware from the phone’s charging components down to the charging equipment and port in use.

How to troubleshoot software-related problems with charging on your Galaxy J7?

Below is a rundown of possible solutions and applicable workarounds to deal with charging issues on the Galaxy J7 including slow charging or not charging at all. Be sure to test your device after performing each procedure so as to determine whether the problem has been resolved. If not, try the next applicable solutions and/or recommendations.

Check and ensure your charging equipment and charging ports are working

As much as possible, try to rule out the possibility of a faulty charging component causing your phone to not charge. To do so, run a thorough check on each of your charging paraphernalia and spot any possible signs of damage. If there’s none then that’s not the cause. Otherwise, try to use an alternative charger or adapter that is compatible with your device. If you have an extra OEM charger or adapter, then that would be better.

You can also try to use a different charging port or power source. If you are using a wall charging then try charging your device through a computer’s USB port or vice versa.


Force your device to restart then charge

A force restart is often recommended to fix device issues on frozen or unresponsive display and minor system glitches. The process is a simulated battery removal. It does not affect your personal data on the device too. Here’s how it’s done:

  • Press and hold the Power and Volume Down keys simultaneously for about 30 seconds or until the device restarts.

Performing a force restart does the same as soft reset on the device, which rectifies software glitches that might have prevented it from charging. Note that not all charging issues are triggered by hardware damage. In fact, many people who have dealt with charging problems later found out that a faulty software was actually the culprit. There might be some corrupted files or broken segments in the software, which barred the charging system from performing its job.

Give it more time to charge

Sometimes it will take longer for a device to show the charging indicator especially when it got totally drained prior to plugging it into the charger. Should this be the case, you can reboot your device once more time then connect it to the charger and let it charge for at least 30 minutes or up to 2 hours.  That should be ample time for the charging system to process the request to refuel the battery.

Remove and re-insert the battery

Doing so will eliminate the possibility of a battery issue halting the device from charging properly. A device may not charge if the battery is dislodged or not secured in place. To make sure this isn’t the issue, remove the battery and then insert it again. Here’s how it’s done:

  1. Remove the back cover using the slot on the upper left of your device.
  2. Lift the cover up and towards the right of the device.
  3. Gently pull the battery from the device then check it to ensure no traces of possible damage like swelling, scratches, or liquid damage.
  4. If everything is good with the battery, insert it into the opening on the back of the device. Make sure the connectors are properly aligned.
  5. Gently press down to secure the battery in place.
  6. Place the back cover onto the back of your phone then press down to secure it in place.

When the battery is secured, plug your device into the power source then see if it is now able to charge.

Connect your device to a laptop computer

Connecting your Galaxy A3 to a computer will help you isolate whether or not the charger or power adapter is working. If your device responds or charges when plugged into a computer’s USB port, then most likely the charger or adapter has an issue. In this case, examine the charger or adapter for any possible signs of damage. Also care to inspect the port for any debris that might prevent contacts between the connectors.

Once you finally get your Galaxy J7 to charge, calibrate the battery then. Doing so will help optimized and prolong the battery’s lifespan. The process of battery calibration involves turning the device off then back on. Next, drain the battery by using the device normally until the battery gets totally empty. Charge it again until the battery gets full, then use the device as you normally do. You can calibrate the battery once every three months to make sure the battery system is optimized, robust and stable.

Other charging tips and options

  • Do not use your device while charging. Bad charging habits like using the phone while charging can lead to battery issues in the long run. While your phone is capable of multitasking, it doesn’t apply when charging.
  • Avoid using third-party charger or charging accessories. Some chargers or adapters are not compatible with your device firmware so there’s a chance for them to break either the battery or the device itself.
  • Do not overcharge your device. A notion about Too Much Is BAD is also applicable when charging smartphones. Thus overcharging can break the battery in time.
  • Remove any casing or cover. Some casing, particularly the ones created by third-party manufacturers do not really fit with the actual device’s scheme. So there is a tendency that the casing can block the charging port and prevents proper contacts.
  • Factory reset (optional). If you can get your device to charge again, you may perform a factory reset or master reset to eradicate any types of bugs that might have corrupted the charging system. While this will cause you to loose your personal data, it gives your device a clean fresh start.

If the problem persists and your Samsung Galaxy J7 still won’t charge, then at this point you may already consider opting for service. Or you may contact your device carrier or Samsung Support for further assistance and recommendations. If your device is still covered by warranty, then don’t forget to avail for warranties instead.
