Sooner or later, most users have encountered problems related to the USB input of the mobile , either because in a specific position the mobile does not charge or because suddenly there is no way for this to work. It is true that it is becoming less common since by forgetting the Micro USB, we find much less with this error, but even so it continues to be repeated.
To try to help you repair the USB port of your smartphone , we have prepared this complete guide with which we hope to clear up your doubts and allow you to fix the connector. A process that can be simple or difficult, varying depending on the situation of the USB port, our knowledge of disassembling mobiles and also depending on what we want to complicate ourselves.
Before disassembling the mobile …
If you have come this far with the idea of getting to work to change the telephone input, we advise you to rethink it first and put other possibilities on the table. We must be very sure of what we are going to do before taking that important step and therefore we invite you to try first with another compatible cable, with a different current transformer and even connecting the mobile phone to the computer since the problem could be different from what we think.
Check what happens to the USB input
Once we have found that the problem is with the USB input of the smartphone , we have to put our sights on it and never better said, since we are going to use a flashlight to look inside. We know that it is complicated but by paying attention to this space we can see if the connectors are bent or what is actually happening to it, something for which it is not necessary to disassemble it.
USB port fails due to dirt
On more than one occasion we have found that the only problem that is generating an error to be able to charge the mobile is the accumulated dirt. It is one of the most repeated problems and which is a joy for those who already had in mind to disassemble the phone. By following the steps to clean the USB input of the mobile, we will be able to recover its operation.
Can we charge the mobile even if the USB is damaged?
A question that we have to ask ourselves and assess whether we can really continue to use the load despite being damaged. In many cases, only one of the connection pins is not in perfect condition, and you can continue to use the upload and transfer of files, but nevertheless it is a risk to use the mobile in this state.
We can ignore it for a few days until we have time to repair the USB input of the mobile but in the long run it can be dangerous, causing a short circuit and making our mobile unusable, as well as much worse situations.
How much money does it cost to change the USB input of the mobile
In case we already know that if or if we have to fix the USB input of the mobile and we do not want to get into trouble, we can choose an official store or an authorized technical service that gives us the peace of mind that the work will be a success . To know the price of our specific model, we will have to consult it personally, since each service changes prices and especially each smartphone may have a different price since not all use the same mechanism.
Even so, consulting prices in different services we can establish that the cost of repairing the USB input starts from 35 euros and can reach up to 85 euros in the newer high-end phones.
Fix the mobile USB for us pampering
At the point of repairing on our own, we must know that changing the USB port of the mobile requires us to be aware that we are going to do an expert level repair that not just anyone can do. A very complex process that could get complicated and put us on the ropes.
Do it only if you no longer have a guarantee
Although we have experience changing USB connectors of the mobile or other elements, we should not try to repair it ourselves if the smartphone has a warranty. It is very likely that the repair falls within the stipulations of the brand and thus we will not lose advantages such as water resistance. Even if we have a guarantee and we open it ourselves, we will be losing the months or years that we have left of buyer protection.
Is there a difference between micro USB port, Type C and Lightning?
One question that may arise before we get down to work and fix the USB input of the mobile is if our repair process can change depending on the phone we have and obviously this is the case, first of all because the spare part that we have to buying is different for each terminal . However, the process does not usually change much between the different connectors and all of them are based on a connection to the motherboard which each is more common to be joined with solder.
All the steps to follow
As in every repair, the first thing we have to do is create a backup copy of the files and move them to another device so as not to lose them in case of problems. Next, we are about to turn off the mobile to open it. To make the opening easier, it is reasonable to apply a slight heat with the help of a specialized iron, and then gradually take off the frame from the back.
Once we have managed to remove the back cover completely, we have to carefully remove the sticker that usually protects the battery and the rest of the connections to the motherboard. In this way we can proceed to disconnect the battery to save ourselves problems. We will do all this with non-conductive plastic tools.
Just above the battery is usually located the motherboard to which the USB input of the mobile is connected and which we will have to completely discount. Once we disconnect all the flexes, the most delicate moment arrives. We also have to remove the USB input connector , which can be attached to a small plate that is removed with the help of screws and then the connector will be soldered to this plate and therefore we will need patience and advanced tools to achieve take it off.
Once removed, we have to clean it in the best possible way, eliminating all the remains of the previous weld. Finally it will be time to put the new USB input on the board and solder it . Then we screw the little board and connect it all to the motherboard again to finish fixing the mobile USB successfully.
We will have to be careful not to forget to connect anything and test it before fixing the back cover with a special glue that prevents it from opening and water can enter, although its protection will hardly be like the original.
