What to do if your phone is not charging

There are several reasons why your device might not charge, and most can be fixed without any extra support. The most common reasons for a device failing to charge are:


  • Faulty cable, charger, socket or adapter
  • Dirt or debris in the charging port
  • Third party apps interrupting the charging
  • Software update is required

1 Use an official charger.

Although most phone chargers and charging cables look similar, there can be a huge difference between their quality and charging speed. It is always recommended to use the charger that came in the box or an official Samsung replacement as these have been specially made for your device and are designed to maximise battery life. Check to make sure that you are not using counterfeit accessories.

2 Check for damage.

If you're using an official charger, check to ensure that there isn't any damage to the cable or plug. If you notice any damage, stop using the charger immediately.

3 Try a new cable.

Even if there is no obvious physical damage to the cable or the plug, try using a different cable and plug to eliminate this as the problem. To make sure that your cable / plug works, try charging a different phone to see if it works or not.

4 Try a different power source.

Once you are sure that your cable / plug work, try plugging them in to a different power source. For example, connect the charger to a power socket rather than a laptop or PC.

Clean the charging portClick to Expand

One of the most common causes of charging problems is if the charging port is clogged with dirt, dust or debris. Dirt or lint can build up inside the charging port and prevent the charging cable from engaging properly with the charging contacts inside the port. This can stop your phone from charging properly or prevent it charging at all.

1 Power off your device.
2 Shine a torch into the charging port and look inside. If you can see dust or dirt, especially if it is covering the metal charging contacts, the charging port needs cleaning.
3 Try gently blowing into the charging port to remove dust and debris.

Please note: Do not insert any object into the charging port. This can result in damage to the charging port.

4 If the charging port remains clogged, take it to a professional to be cleaned.
Check for water and moistureClick to Expand

Your device will not charge if it detects water or moisture in the USB port. This is a security measure to protect the device from damage and corrosion. If your device has detected water in the charging port, it will sometimes display a waterdrop icon on the screen above the charging port. If you see the waterdrop icon, make sure that your device is turned off while it dries.


Most moisture will evaporate by itself within a few hours, but you can also try blowing gently on the port or exposing it to cool, dry air. If the waterdrop icon has still not disappeared but you are sure the charging port is dry, try turning your device off and on again.


If the icon remains after this, clear the cache for USB:

1 Go to "Settings", then tap "Apps".
Tap Apps menu on Galaxy S10
2 Tap the More options icon.
Tap the More options icon on Galaxy S10
3 Tap "Show system apps".
Tap Show system apps in Apps menu on the Galaxy S10
4 Scroll down, then "USBSettings".
Tap USBSettings in Apps menu on the Galaxy S10
5 Tap "Storage".
Tap Storage in USBSettings menu on Galaxy S10
6 Tap "Clear Data" and "Clear Cache".
Tap Clear data and Clear cache in USBSettings menu on the Galaxy S10
Try a wireless chargerClick to Expand

If you think the problem is related to wired charging and your device is compatible, try charging your device using a wireless charger. Make sure to remove any cases or covers first and lay the back of your device onto the wireless charger making sure to line up the charging coils to establish the strongest possible connection.
