How to Fix Galaxy S25 Ultra Charging Starts Then Stops

Some Galaxy S25 Ultra owners report that their phone has stopped charging, charges intermittently, or fast charging no longer works. The following troubleshooting steps address the most common charging problems.

Fix #1: Check the Charging Cable and Adapter

A damaged or non-certified cable is the most common reason the Galaxy S25 Ultra stops charging or charges slowly.

1. Try a different USB-C cable.
2. Try a different power adapter (25W or higher for fast charging).
3. Plug directly into a wall outlet rather than a power strip or computer.

Fix #2: Clean the USB-C Port

Lint, dust, or debris in the charging port can prevent a solid connection.

1. Turn off the phone.
2. Use a wooden or plastic toothpick to gently remove any debris from the port.
3. Blow gently into the port or use compressed air.

Fix #3: Force Restart

1. Press and hold Volume Down + Power for about 10 seconds.
2. Release when the Samsung logo appears.
3. Plug in the charger after the phone restarts.

Fix #4: Boot into Safe Mode

Third-party apps can interfere with charging. Safe Mode disables all third-party apps temporarily.

1. Press and hold the Power button until the power menu appears.
2. Long-press Power Off until the Safe Mode prompt appears.
3. Tap Safe Mode.
4. Test charging in Safe Mode. If it works, a third-party app is causing the issue.

Fix #5: Wipe Cache Partition

1. Turn off the phone.
2. Hold Volume Up + Power to enter Recovery Mode.
3. Select Wipe Cache Partition.
4. Reboot and test charging.

Fix #6: Check for Software Updates

1. Go to Settings > Software Update > Download and Install.
