Hi! I have a Galaxy S21 which is still under warranty. I've been using an original Samsung 25W charger and cable with it throughout. Today, the phone has suddenly stopped Super fast charging or even fast charging. It shows Cable charging. I've tried changing the charger and cable and used the one which came with Note 20 Ultra but the issue persists. Please help

3. Make Sure Fast Charging Is Enabled

After confirming that your phone supports fast charging, you should check that fast charging is enabled in your phone's settings. It won't work if it's disabled in the settings. Follow the steps below to check whether this option is enabled:

Go to the Settings app.

Tap on Battery and device care > Battery.

Tap More battery settings.

Make sure all toggles under Charging are enabled

Hello, We understand the importance of being able to superfast charge your phone! For those who have updated their phones to One UI 4.1.1, please take a look at the following:

One UI v4.1.1 shows the type of charging being used in the following two ways:

       1. In the Notification panel, the charging type displays for the first five (5) seconds (e.g. “Fast charging started”

  • After the first five (5) seconds, the device will only display “Charging” regardless of the type of charging being used

      2. From the Lock screen, the Battery icon and the remaining charging time for a full charge will show for the first five (5) seconds

  • After the first five (5) seconds, the device will display only the charging icon​

If the phone is slow charging or will not charge, this article contains several steps that may correct the concern. https://www.samsung.com/uk/support/mobile-devices/my-device-is-charging-slowly-not-switching-on-or-k... 

 

In the event the phone is not charging and troubleshooting is not helpful, it is recommended to have the phone evaluated at an authorized service location. You can use the following link to find a list of service centers in the U.S. that can do the repair: http://www.samsung.com/us/support/service/location
