How to Troubleshoot a Broken Micro USB Port


Has the USB port on your cell phone stopped functioning or become loose?

Is the USB cord refusing to sync and not charging?

Having a loose micro-USB port means you will be unable to retrieve data from your mobile device or charge your battery.

The two major causes of USB port damage on mobile phones are:

  1. An improper connection such as using an incorrect USB type or plugging the phone upside down.
  2. Removing the cable incorrectly or forcefully.


There are simple ways you can use to troubleshoot a broken micro USB port and get it working again.

  1. Toothpick Method:

The toothpick is one useful item which you can find for free in virtually any restaurant. Using the toothpick to clean the inside of the USB port is an easy way to fix a loose micro-USB port. Naturally, a micro USB charging and data port are designed to be quite strong but over time it will get loose and become quite useless. Notwithstanding the fact that your cell phone cannot hold the USB connector plugs firmly anymore, applying the trick of cleaning the inside of the USB port with a toothpick can solve the problem. All you need is a thin and sharp toothpick, and you do not necessarily have to open the device.

You should sharpen the toothpick and make it smaller so it can fit well into the USB port. Once you poke and scrape the inside of the USB port, all the dirt’s and junks that have accumulated overtime will be revealed. After doing this, you will discover that the USB port will not be as loose as it previously was and it will now work flawlessly like it was new.




  1. Lint and Dirt

Lots of mobile phone users carry their phones in their pocket and eventually, lint will find its way into the USB charging port, and this will prevent the charging cable from creating a connection with the port contacts. There are small hooks in the USB cable jacks that interlock with the charging port and these hooks will not latch properly with the USB port because of lint.

Apart from lint, cell phone ports are also exposed to lots of debris like sand, dirt, and dust. This debris will overtime affect the fitting of the USB cable thereby preventing it from properly charging. Every cell phone user should endeavor to practice preventive maintenance as you might end up spending a lot of cash due to your negligence and carelessness.


  1. Device Protection

If the USB port is not being regularly used, it should be sealed. This will prevent the cell phone user from having a broken USB port. Most mobile phone manufacturers are well aware of the hazards involved in having an open USB port, and that is why modern designs usually come with a built-in port cover.

Another cost-effective way to protect your micro USB port is by using an accessory called dust plug. A dust plug is made from flexible silicone, and it helps in keeping out debris. It is compatible with all cell phone models and helps in increasing the protection level of your USB port thereby saving you from costly repairs.
