Check if the USB port is damaged
Now that you have clear the USB port, you can connect the phone to a charger and check if it makes any difference or not. If it doesn’t, it is quite possible that the USB port or the metal tab inside it is damaged or has deformed due to constant wear and tear. You can peep inside the port using a torch. If the port is damaged, you’ll have to get it replaced from a service center unless you know everything about the phones and how to repair it.
Diagnose the cables
No, it is not a secret that the charging cable is subjected to constant wear and tear. It won’t get damaged if you keep on keeping the phone still on a table near the power outlet and charge the phone but we never do it. We usually take the phone upside down or sideways and even roll it and what not and that’s all when the phone is connected to the charge via cable. Thus, the charging cable is subjected to constant stretches, tears, cuts, swirling and twisting and what not. This can render the cable useless at a certain point and if the phone ain’t charging assuming that you scrutinized the USB port to be fine, you may have reached that point where you must get a new cable. But before that, you can use the same cable on another smartphone to verify the issue. If it doesn’t work then it’s time to get a new cable instead.
Scrutinize the adapter/brick
The adapter or brick is one of the important parts of the charging process as it converts the incoming amperage into wattage which is then sent to the battery and so on. If you are using the original charging brick provided by the manufacturer, it must have at least 6 months of warranty and the same goes for the cables. You can verify if the cable or the brick are damaged by using a reference phone to charge it. On the contrary, if you are using a third-party brick, either it might be incompatible or it could be damaged and needs a technician to fix it. Note that since it is a third-party accessory, you can report the problem to a technician nearby and get it repaired or replaced.
Have a look at the battery
Now, there can be a number of explanations. First of all, it is quite possible that the battery has developed a fault and it is charging but either slowly or if you are using the phone simultaneously when it is charging, the phone is consuming more battery power than it is drawing from the power outlet and that is causing the Walton not charging problem.
Another explanation could be that the battery is damaged or has completed its life cycle since batteries that come installed in a smartphone has a specific life cycle during which, it starts to deplete gradually until it succumbs to death. In such a case, you’ll have to replace the battery by buying a new one and that’s how you’ll get a new battery, higher battery life, and more benefits.
Get help from the professionals
Yes, this is the final thing you can do to get the Walton not charging problem fixed. If you are unable to find the culprit, simply call and book an appointed with an authorized service center and walk-in to one if needed and report the problem. Although it might take few hours to few days depending upon the severity of the issue and yes, there will be a premium to pay if the problem is not covered in warranty, you can opt for it too.
