How To Fix Samsung Galaxy S21 Ultra Charging Issues

Check Your Charging Cable and Adapter

The first step in diagnosing and fixing charging issues is to examine the hardware components involved in the charging process. Start by inspecting your charging cable and adapter. Look for any visible damage, frayed wires, or bent connectors. If you notice any issues, it’s crucial to replace the faulty components with new, high-quality ones that are compatible with your device.

Clean Your Charging Port

Over time, dust, debris, and pocket lint can accumulate in your phone’s charging port, preventing a proper connection. To clean it:

  1. Power off your Galaxy S21 Ultra.
  2. Use a small, soft brush or compressed air to remove any debris from the charging port gently.
  3. Avoid using sharp objects that could damage the port.

After cleaning, try charging your phone again to see if the issue has been resolved.

Restart Your Phone

Sometimes, a simple software glitch may be causing charging problems. Restarting your Galaxy S21 Ultra can help resolve these issues. To restart your phone:

  1. Press and hold the power button and the volume down button simultaneously.
  2. Hold both buttons until the Samsung logo appears on the screen, then release them.
  3. Your phone will restart, and you can check if the charging problem persists.

Check for Software Updates

Samsung regularly releases software updates that include bug fixes and improvements. Ensuring that your device is running the latest software can potentially resolve charging issues. To check for updates:

  1. Go to “Settings.”
  2. Scroll down and select “Software update.”
  3. Tap “Download and install” if an update is available.

Safe Mode Troubleshooting

Sometimes, third-party apps can interfere with the charging process. Booting your Galaxy S21 Ultra into Safe Mode can help identify if this is the case. Here’s how:

  1. Power off your device.
  2. Press and hold the power button until the Samsung logo appears.
  3. Release the power button and immediately press and hold the volume down button.
  4. Keep holding the volume down button until the phone finishes restarting.
  5. In Safe Mode, your phone will only run essential apps. Check if the charging issue persists.

Battery Calibration

Battery calibration is a useful step to consider if your phone’s battery percentage doesn’t seem accurate or if it’s draining quickly. To calibrate the battery:

  1. Charge your Galaxy S21 Ultra to 100%.
  2. Use your phone until the battery drains completely and the device shuts down.
  3. Charge it back to 100% without interruptions.
  4. This process helps recalibrate the battery percentage readings.

Factory Reset as a Last Resort

If all else fails and your Galaxy S21 Ultra is still experiencing charging issues, a factory reset may be necessary. Be sure to back up your data before proceeding, as a factory reset will erase all data on your device. To perform a factory reset:

  1. Go to “Settings.”
  2. Scroll down and select “General management.”
  3. Tap “Reset,” then select “Factory data reset.”

Follow the on-screen instructions to complete the reset.


Charging issues with your Samsung Galaxy S21 Ultra can be frustrating, but with the steps outlined above, you can effectively troubleshoot and resolve these problems.
