How to Know If Your USB Charging Port is Damaged? (2023)

A damaged USB charging cable may not make good contact with the USB port on your device. This can be caused by bare wire, damaged insulation, and corrosion. Fortunately, there are ways to detect if your USB port is damaged. For example, you can check the cord to find if it’s rusted or stripped.

Many phone scratches and charging woes result from a damaged USB charger port. So how do you know if the port is wrong or not? There are several ways to tell, but the easiest way to test it is by plugging in your charger and seeing if your device will charge successfully. If you find that this doesn’t work, try plugging your charger into another device, like an iPad or computer. If an iPad can charge successfully but your phone cannot, then there must be something wrong with the USB charging port on your phone.

Some people opt to replace their damaged USB charging port with a more expensive alternative rather than purchasing a replacement cable. However, this is unnecessary, and the replacement cable should work fine (as opposed to an expensive USB charging port).

If you find that your phone is only charging when a certain amount of pressure is put on the USB charger, then there must be something wrong with your phone. In this case, you are stuck buying a new charging cable and possibly a new USB charger port.

Some people have reported that their phone only charges appropriately at a certain angle. This can be due to a lousy USB charger port or some other issue that may require you to get your phone checked out by an Apple technician.

If the outlet you are using for your USB charging ports is broken or damaged, this can also cause problems with charging. In this case, a replacement outlet port can fix the problem.

If your phone only charges when certain specific apps are open, you may have a hardware issue with your phone’s internal components. In this case, you will need to get an iPhone technician to check out your phone and ensure that nothing is wrong internally that could prevent it from charging correctly.

If your iPhone only charges when driving down the road, this may be due to an electrical problem with your car. However, given the nature of iPhones and their poor battery life, you really shouldn’t expect them to be able to last for very long when connected to a car outlet.

Phones that have moisture damage will often not charge correctly or at all. If your phone doesn’t charge when it has moisture damage, you’ll need to get an iPhone technician to check out its internal components and ensure there is no permanent damage.

In some rare cases, if your iPhone isn’t charging correctly, you may have a problem with your SIM card.

A Damaged USB Charging Cable

If your USB charger isn’t working, you might have a damaged cable. Damaged cables will have exposed wire or stripped insulation and wire shielding. You can check this by plugging the charger into another device and seeing if the problem persists. If it does, you should consider getting a new cable.

Generally, a USB cable consists of four wires, although newer models have eight wires. The inner wiring is made from four different colors. If one color is exposed, you should carefully twist it tightly. If you cannot do this, you can cover the metal with electrical tape.

A damaged USB charging cable sometimes won’t make good contact. This can be caused by the cable being dirty. If you try to clean the cable, you may damage the pins inside. Be careful when cleaning a USB cable because it can cause an electrical shock or even a minor explosion. This can damage the device or the user.How to Know If Your USB Charging Port is Damaged? (1)

Another sign that a USB charging cable is damaged is that the wires inside the charger are bent. This happens when the cable is repeatedly plugged and unplugged. If the wires are bent, the USB cable won’t be able to operate correctly. In some cases, the cable can break because the wires are crimped.

A USB charging cable’s quality should be checked before purchasing it. Low-quality cables will likely damage devices due to their shoddy construction and poor materials. Cheap ones are made with thin wires and cannot withstand frequent bending. They also often feature loose plugs and sockets. These can lead to poor connection and overheating.

A damaged USB cable can cause your device to stop charging. The cable may not be MFI certified, or its controller chip may not be able to handle the current. It may only work with 5 volts or less. Some cheap cables can be damaged due to sunlight, heat, or excessive current.

Another way to tell if your cable is damaged is by comparing the current it puts out. A USB charging cable with a similar output current is healthy. If it is different, it is defective. Try comparing it with another charger or cable for your smartphone. You should use different measurements if you’re using the charger with quick charging.

Bare Wire

There are several ways to tell if your charging port is damaged by bare wire. First, if the wires are damaged, a spark should be produced when you touch them together. If the spark is not present, you can use needle-nose pliers to reshape them or soldering iron.

You should strip the protective shielding and rubber if the wires are exposed. This will reveal bare metal wires connecting the two parts of the charging cable. The white and black wires are connected with the bare metal wires. If the wires are not exposed, they will short out when they touch each other.How to Know If Your USB Charging Port is Damaged? (2)


If the wires are damaged, you should not charge your phone with them. This will result in an electrical shock. Instead, it would help if you tried disconnecting the damaged charging cable from a working outlet. Make sure to disconnect any extra components from the charger first. If the charger works correctly, then you can add them back. However, it would help if you were careful when wiggling the cable since you may cause an electrical shock.

Stripped Insulation

If you have a laptop and find that your charging port isn’t working, it may be time to replace the insulation. There are two ways to repair this problem: repair it at home yourself or take it to a repair shop. Here are the steps you should take:

First, you must check the wires. You should find the red and black wires at the charger head. These wires are responsible for transmitting power and data. If they are stripped or damaged, you can fix them using a soldering iron. Make sure that you don’t cut the wires inside the casing.


One of the most common problems with your smartphone is a damaged charging port. This can happen for several reasons. The charging port may erode if your smartphone is constantly in water or a high humidity environment. Debris from the port can also clog the contacts, making it difficult for the phone to charge. Cleaning the charging port should clear any debris.

If you notice that the charging cable is not fitting into the charging portal, the charging port has likely been damaged. The charging portal is made up of pins that fit into the charging cable, and if the pins are damaged, the phone won’t charge properly.
