How to Repair the USB Charging Port on a Samsung Phone

If your Samsung Galaxy S10, S9, S8 or other Samsung phone won’t charge, has a loose charger, or its charging cable falls out of its mini-USB charging port, chances are pocket lint is the culprit. Many smartphone users carry their phones in their pockets, and over time lint works its way into the USB charging port and prevents the charging cable from making a solid connection with the port contacts. In addition, USB cable jacks have small hooks that interlock with the charging port, and lint can also make it impossible for these hooks to properly latch. Fortunately, it’s easy to repair the USB charging port on Samsung phones. Here’s how to do it, plus how to replace your Samsung phone’s charging port if lint isn’t the problem.

How to repair the USB charging port on a Samsung phone

The following steps detail how to repair the USB charging port on a Samsung phone, regardless of the model you have (Galaxy S10, Galaxy S7, etc.):

1. Turn off your Samsung phone and disconnect it from the charger

2. Look into the charging port; you’ll notice the small card containing the contacts the charger connects to

3. Insert a small needle into the charging port and slowly, gently swipe it through the space between the contact card and the USB port walls




4. As you swipe, gently pull the needle toward you and out of the port to remove lint

5. Continue swiping the needle around the port until all the lint is removed

6. Now, your charging cable should latch properly and your contacts should make solid connections in the charging port. Your Samsung phone should charge normally

NOTE: Be careful not to damage the card contacts with the needle, and attempt this fix at your own risk. If this fix does not work, you may need to replace your charging cable or USB charging port.

How to replace your Samsung phone’s charging port

You can replace your own Samsung phone charging port, mail it in for replacement or take it to a local repair shop. Professional repair runs between $40 and $100, depending on which model you have, while the DIY method costs between $5 and $20 for replacement parts. You can buy phone repair kits for as little as $5.

If you decide to replace it yourself, the process typically involves removing the back cover or rear glass, unscrewing and removing various components, then replacing the charging port assembly. It can be a difficult repair if you’re not experienced, and you can risk damaging your Galaxy even more. You can find detailed repair guides on iFixit and YouTube.

See if your phone is under warranty or covered by insurance before you spring for repair. Warranty replacements are usually free and some phone insurance plans have relatively low deductibles.

If you have an older Samsung phone or you’re ready to upgrade, it might not be worth replacing the charging port – especially since you can sell a broken phone and use the cash toward a new phone.
