How to know if charging port is damaged

Updated: November 28, 2023

Regular use, excessive strain, and careless handling are the most common causes of damage to charging ports. This article will discuss other reasons leading to the breakdown of the charging port, how to identify a malfunctioning charging port, and what to do with a faulty charging port.

Signs of a Faulty Charging Port

You can identify a malfunctioning charging port in two ways:

  1. Visual inspection.
  2. Testing the port’s functionality.

A visual inspection is the easiest and most accessible way to assess the functionality of a charging port. In most cases, a charging port’s malfunction can be identified immediately with good lighting and a magnifying lens. Visual inspection allows you to identify mechanical damage and burn marks due to short circuits. A loose connector or the smell of burnt plastic can also indicate a malfunction.

Visual inspection can often help you see physical damage to your phone's charging port.

Testing the functionality of the charging port involves connecting a cable in various modes. To test a phone’s charging port, you should connect a USB cable through a PowerBank, a wall charger, and a PC USB port. If the phone charges when connected to all devices, then the power lines are not damaged. The absence of charging when connected to any device indicates hidden faults. It’s also advisable to try different USB cables, as the cable can often be the problem. You should check the operation of OTG connections and connections to a computer. If the connection does not work and the charging port visually appears to be in good condition, the problem may be inside the phone due to damage to the connection lines on the motherboard.

For testing the charging port of a device, various tools can be used. The simplest diagnostic method is to connect a USB tester. You can also measure the presence of current and voltage on the contacts using a multimeter.

Causes of Charging Port Breakdown

All charging port malfunctions can be divided into two main categories:

  1. Mechanical.
  2. Electrical.

Mechanical faults occur during the use of a phone, tablet, or charging device, etc. Excessive force when connecting or disconnecting the plug, bending the cable at the connection point, as well as impact or strong vibration, lead to wear and tear of the port. As a result, the charging port becomes deformed, or the connector or contacts inside the port are destroyed, making it difficult or impossible to use due to loss of functionality.

Electrical faults also arise during use due to non-compliance with the rules for using the phone, tablet, or charging device, etc. The presence of moisture or metal parts inside the charging port leads to short circuits and burnout of the connection contacts. Breakdowns can also occur due to the use of damaged or poor-quality USB cables, voltage fluctuations, etc. The danger of electrical faults is that they can spread to other components of the phone or charging device. Not only the power connector can burn out, but also the conductive lines on the board, various power controllers, and microchips. As a result, the cost of repair significantly increases compared to mechanical damage.

Water can often burn the charging port or components on the charging board.

What to Do with a Faulty Charging Port?

A faulty or damaged charging port should be replaced. Replacement can be done independently if you have some repair experience and suitable tools. In some phones, you can get by without replacing the charging port by replacing the entire connection board. The cost of such a board is slightly higher than just replacing the charging port. On the other hand, almost any user can perform this modular repair. If the phone supports wireless charging, then you can delay repairing the charging port indefinitely.

In a charging device, replacing the charging port is mandatory; otherwise, it’s impossible to use the charging device normally. The exception is for 2-5 port charging devices, where you can continue to use other ports for charging. However, before using such a charging device, it is important to ensure the proper condition of the charging device and other charging ports.

In some cases, the charging port can be repaired by cleaning with concentrated isopropyl alcohol.

Conclusion

A faulty charging port can be identified visually and through various tests. Visual inspection allows you to identify physical damage and wear of the port, as well as to replace signs of burning due to a short circuit. You can check the functionality of the charging port using tests with a USB tester or by connecting additional devices. Don’t forget about the possibility of hidden faults, detectable only by fully disassembling the case.

FAQ

Can a damaged charging port be fixed?

If only the charging port is faulty, it can be completely replaced to restore proper condition.

How do I test my charging port?

Inspect the charging port for visible damage. Connect a cable and check the reliability of the connection. A loose port needs to be secured by soldering. You can connect a USB tester to the charging device’s port to check its functionality.

What do I do if my charging port is damaged?

A faulty charging port needs to be replaced. You can replace the port yourself or go to a service center.

How do I know if my charging port is bad or the battery?

With a faulty USB port, you won’t be able to charge the battery. With a faulty battery, the phone will not work.

Is it expensive to fix a charging port?

The cost depends on the complexity of the repair. In most cases, port replacement is not a complicated or expensive process. However, disassembling some phone models can be more challenging.

What is the lifespan of a USB C port?

The lifespan of a USB-C port is estimated by the number of plug-ins and unplugs. A USB-C port withstands up to 10,000 connections and disconnections. However, careless use and excessive strain can lead to port failure much earlier.

Can a faulty charging port affect battery life?

Usually, the charging port does not affect the battery’s lifespan. However, the charging port can be an indirect cause of breakdown due to a short circuit inside the charging port.

Why is my phone charging but not going up?

There may be damage to the power lines or damage to the microchips responsible for charging the battery. In most cases, you will have to disassemble the phone case to access the motherboard for subsequent diagnosis.

Can a charger damage a phone?

Any charging device can lead to phone breakdown due to voltage fluctuations or a short circuit. Quality charging devices contain several levels of protection to prevent phone breakdown. Therefore, it is important to use the phone manufacturer’s charging devices or quality alternatives from well-known brands.

How can I charge my phone without a charging port?

You can charge the battery using wireless charging or remove the battery and charge it using an external charging device. However, the option with an external charging device is not suitable for regular use of built-in batteries.

Can a dirty charging port affect charging?

The presence of moisture or metallic dust can create a short circuit and lead to charging problems. Usually, a fuse trips and charging stops. In some cases, the negative effect is minimal, and the phone continues to charge, gradually damaging the charging port.

How long does a charging port repair take?

If only the charging port needs to be replaced, the repair can take up to two hours. If there is another fault in the phone besides the charging port, the repair duration can significantly increase.
