When a Samsung Galaxy J5 no longer charges, aside from panicking, it helps to remember that you don’t necessarily have to run and buy a new charger. Don’t act on an impulse and consider that the phone or the battery may be defective. At the same time, the charging unit, the charging cable or the connectors that make contact with the battery may be faulty. Even a temporary phone bug could be involved so, take a few moments to try out the following simple fixes before anything else.
Test how your USB cable works
One of the first things that will cross your mind is that it’s either the phone or the cable at fault. Since a USB cable is cheaper and easier to find, chances are you already have one around the house. Use it to see if a different cable will charge your Samsung Galaxy J5 or not. If you don’t have another cable, ask someone’s help to test if your USB cable is charging their smartphone. Either way, it shouldn’t be hard to determine whether the cable you’re using is functional or not.
Refresh the system with a simple reset
You should reset your Samsung Galaxy J5 every now and then. Especially now, when you’re having this charging problem, you must take into account a possible software bug. The reboot may fix that and even the charging issue itself. You can’t know until you try it and, while you do so, bear in mind that even if it works, it could be merely a temporary solution. A comprehensive guide on how to do that is available right here.
Do a cleanup of the USB port
As long as you can tell for a fact that the USB cable is perfectly functional (and you just tested that), it is worth assuming that there may be something blocking that connection between the USB cable and the smartphone. The USB port is the easiest thing to check and more often than not, people find in there all kinds of debris, lint, dirt or other tiny particles. It takes as little as one needle or a paper clip to gently clean that USB charging port. The difference may be huge and, if that was the problem indeed, you should be able to solve it quite easily.
Consult an authorized technician
It’s not the first time you hear this and certainly won’t be the last one. Your situation is classic – you just don’t know what else you can do on your own. So, instead of trying who knows what methods and risking to damage the phone for good, stick to what you know and what you can do – take your Samsung Galaxy J5 to a Samsung technician. With warranty or not, this is the most comfortable and safest alternative left.
