Fast charging not working

We sincerely apologize for any inconvenience this may have caused. To enable the fast-charge or fast wireless charge feature for Galaxy mobile devices, please follow the steps below:

1. Go to Settings > Device Care.
2. Tap on the Battery icon.
3. Tap the Charging menu.
4. Select one of the charging modes below, based on the type of authorized fast charger you have:

- Fast charging: Enable this mode if you are using the Adaptive fast wired charger.
- Super fast charging: Enable this mode if you are using a wired Super fast charger.
- Fast wireless charging: Enable this mode if you are using a fast wireless charging pad.

To enable any one of the charging modes, simply tap the switch to the right side.

You are unable to use the fast charging feature or the super fast charging feature when you charge the battery using a standard battery charger. To use the fast charging feature, you must use a wired battery charger that supports Adaptive fast charging. To use the super fast charging feature, you must use a wired USB PD (Power Delivery) charger that supports super fast charging.

Thank you for your understanding and patience. We appreciate your loyalty to Samsung and are committed to providing you with the best support possible.
