What to do when Galaxy device has a charging problem?

Last Update date : Jul 25. 2022

It can be frustrating when your phone does not get charged properly or does not turn on. Sometimes after installing an update, your phone restarts repeatedly but never actually boot up. Third-party apps can cause random or constant reboots to happen on your phone. In such cases, follow the steps below to troubleshoot the issues.

Before you try out the below recommendations as to your solution, be sure to check if your device's software and related apps are updated with the latest version. Please check how to update your mobile device's software in the following order. 

Step 1. Go to Settings > Software update.

Step 2. Tap on Download and install

Step 3. Follow the on-screen instructions. 

What to do when your phone is not charging

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
  • The software update is required 
Check your charger

The first step is to check to see if the problem is related to your charger or charging cable. 

Step 1. Use a charger provided with the device.

Step 2. Check for damage. 

Step 3. Try a new cable. 

Step 4. Try a different power source. 

Clean the charging port

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 from charging at all. 

Step 1. Power off your device. 

Step 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. 

Step 3. Try gently blowing into the charging port to remove dust and debris. 

Step 4. If the charging port remains clogged, take it to a professional to be cleaned. 

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

Check for water and moisture

Your device will not charge if it detects water or moisture in the charging 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 or on the notification panel. 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:

Step 1. Go to Settings > tap Apps

Step 2. Tap the More options (three vertical dots) icon > tap Show system apps

Step 3. Scroll down, then tap USB Settings.

Step 4. Tap Storage > tap Clear data and Clear cache

Reboot your device

To check if it is a software-related issue, try rebooting your device when it still has a remaining charge.

Step 1. Turn the device off and wait 10 seconds.

Step 2. Plug in the charger provided with the device. 

You could perform a soft reboot using the buttons. If your device does not have a Home button or a separate Power button, such as Note10, Fold, Z Flip, or higher, press the Volume up and Side buttons simultaneously. When your device vibrates and the Samsung logo appears, release the buttons to reboot the device. 

What to do when your phone does not turn on

Try performing the following steps if your phone does not turn on or power-up: 

Step 1. Verify that your phone has enough charge. 

When the battery is completely discharged, your device will not turn on. Fully charge the battery using a charger supplied with the device before turning on the device.

Step 2. Verify that your phone's charging port is not damaged. 

Carefully inspect your phone to be sure that it is not overheating, swollen, or damaged. Also, inspect your phone's charging port and remove any dirt or debris. 

Step 3. Verify that you are using a compatible charger provided with the device or compatible charger. 

You risk severe damage to your phone if the charger is not the same voltage, amperes, and plug type as the charger provided with the device. 

How to troubleshoot when your phone reboots repeatedly

You can perform a software update, factory reset, or turn on Safe mode to determine if an app is causing the issue first. 

Option 1. Download software updates manually. 

Navigate to Settings > tap Software update > Tap Check for updates

Option 2. Use the Safe Mode feature to identify the app that may be causing the problem. 

You can completely power off the phone and power on the phone, press and hold down the Volume Down key to enter in Safe Mode. 

Option 3. You can do a factory reset in case of an abnormal boot loop. 

    Step 1. Boot into Android Recovery.

  • If the device has a separate Bixby key: Press the BixbyVolume up, and Power button simultaneously.
  • If the device does not have a Home button or a separate Power Button: Press and hold the Volume up and Side key simultaneously.

    Step 2. Use the Volume up and Volume down buttons to select Delete all user data or Wipe data/Factory reset, then press the Power button.

    Step 3. Use the Volume up and Volume down buttons to confirm your selection, then press the Power button.

    Step 4. When the factory reset process completed, press the Power button to select Reboot device

    Step 5. Once your device has rebooted, enter your account details to access your device. 

If these steps do not work and your phone or tablet is still experiencing problems, contact the Support Center for service. 


  • Factory reset will delete all user data. Previously synced Google account details will be required to unlock the phone or tablet. 
  • A hardware factory reset will erase all information on the phone. Any information that is not backed up online or to the SD card will be permanently lost. 

Note: Device screenshots and menu may vary depending on the wireless service provider, device model and software version.
