Solutions

1. Check the Charging Cable and Adapter

A damaged cable or adapter can significantly slow down charging.

Inspect the charging cable for any visible damage, such as fraying or bends.
Try using a different Samsung-certified USB-C cable and adapter.
Ensure you’re using a Samsung 45W Super Fast Charger for optimal charging speed.
Plug the charger into a different power outlet and check if charging improves.

2. Enable Fast Charging

Fast charging may be disabled in settings, causing slow charging.

Open Settings > Battery and Device Care.
Tap Battery > More Battery Settings.
Ensure Fast Charging and Super Fast Charging are enabled.

3. Clean the Charging Port

Dirt or debris in the charging port can interfere with proper charging.

Inspect the charging port using a flashlight.
Use a soft brush or a compressed air can to remove dust and debris.
Avoid using metal objects like pins, as they can damage the port.

4. Close Background Apps

Apps running in the background can drain battery and slow down charging.

Open Settings > Battery and Device Care.
Tap Battery > Background Usage Limits.
Tap Put Unused Apps to Sleep and close any unnecessary background apps.

5. Charge in Safe Mode

Safe Mode disables third-party apps that may interfere with charging.

Press and hold the Power button.
Tap and hold Power Off, then select Safe Mode.
Connect your charger and check if charging speeds improve.
If charging is faster in Safe Mode, uninstall recently installed apps that may be causing the issue.

6. Use a Wall Outlet Instead of a Computer or Power Bank

Charging via a computer or power bank provides lower power output, resulting in slower charging.

Plug your charger directly into a wall outlet instead of a PC or power bank.
Avoid using third-party chargers with lower power output.

7. Avoid Using the Phone While Charging

Using your phone while charging generates heat and slows down charging speed.

Disconnect from Wi-Fi or mobile data to minimize battery usage.
Avoid running high-power apps like games or streaming services while charging.
Let the phone charge uninterrupted.

8. Check for Software Updates

Software bugs can sometimes cause slow charging issues.

Go to Settings > Software Update.
Tap Download and Install.
If an update is available, install it and restart your phone.

9. Reset Battery Usage Stats

Resetting battery usage stats can fix incorrect battery readings.

Open Settings > Battery and Device Care.
Tap Battery > More Battery Settings.
Tap Reset Adaptive Battery and restart your phone.

10. Try a Different Charging Cable and Adapter

Non-certified chargers may not provide sufficient power.

Use a Samsung-certified USB-C cable and adapter.
If possible, test with another original Samsung charger.

11. Disable Battery-Draining Features

Certain features consume battery power and can slow down charging.

Go to Settings > Connections.
Turn off Wi-Fi, Bluetooth, and Mobile Data while charging.
Reduce screen brightness and enable Dark Mode.
Enable Airplane Mode to speed up charging.

12. Perform a Soft Reset

A soft reset clears minor software glitches that may slow down charging.

Press and hold the Volume Down and Power button for about 10 seconds.
Release the buttons when the Samsung logo appears.
Connect the charger and check if the charging speed improves.

13. Contact Samsung Support

If none of the solutions work, the issue may be hardware-related.

Visit the official Samsung Support website.
Schedule an appointment at an authorized Samsung service center.
Explain the issue and follow the recommended troubleshooting steps.

These methods should help resolve slow charging problems on your Samsung Galaxy S25 Ultra. If the issue persists, professional repair or battery replacement may be required.
