Samsung Galaxy device is not fast charging

Use Samsung compatible chargers and cables

Even if chargers and cables look similar, charging quality and performance may vary.

• For optimized charging performance and device safety, Samsung recommends using compatible Samsung chargers and charging cables designed for your Galaxy device.

Check your charger and cable

Using the right charger and cable is key to fast charging.

Here's what you need to know:

• Fast Charging (15W): Use a 15W USB-A adapter and a USB-A to micro-USB or USB-C cable. A 3A-rated cable is enough for this. 
• Super Fast Charging (25W): Use a 25W USB-C adapter. A 3A-rated cable might work but could limit the speed. For best results, use a 5A-rated USB-C cable.
• Super Fast Charging 2.0 (45W - 60W): Use a 45W or 60W USB-C adapter and a 5A-rated USB-C cable. A 3A cable won't work well here.

You can find compatible charging adapters and cables on our website. 

Check the charger connection

If the charger is not connected properly, the device may not charge normally.

• Disconnect the charger from the Galaxy device and reconnect the charging cable securely to the charging port.

Check for charger or cable damage

A damaged charger or charging cable may prevent normal charging.

• Try charging the device using another compatible Samsung charger and cable.
• If charging still does not work, visit a Samsung service center for hardware inspection.

Dust or foreign material inside the charging port is one of the most common causes of charging issues. If dust, lint, or debris builds up inside the charging port, the charging cable may not connect properly to the charging terminals.

1. Turn off the Galaxy device, and then use a flashlight to inspect the charging port.
2. If dust or debris is visible, carefully remove it without using metal objects or liquids.

If your Galaxy device supports fast charging, make sure fast charging is enabled in Settings.

1. Open Settings, then tap Battery.
2. Tap Charging settings.
3. Turn on Fast charging and Fast wireless charging.
   

If Battery protection is enabled, charging may stop early or the maximum charging level may be limited depending on the selected option.

1. Open Settings, then tap Battery.
2. Tap Battery protection.
   
3. Select a different option or turn off Battery protection.
   

1. Check for moisture detection notifications.
   
2. Shake the device gently to remove moisture from the charging port, then wipe the device with a soft, clean cloth.
   
3. Dry the device in a well-ventilated area using cool air.

You can use Samsung Members Phone diagnostics to check the current cable charging condition of your Galaxy device.

1. Open the Samsung Members app, then tap Support.
   
2. Tap Get Started. Start the full diagnostics first, stop the test, and then select the item you want to test. If the diagnostics page does not open properly, try using the Samsung Internet app.
3. Tap Cable charging.
   
4. Check the diagnostic results.
