We apologize for any inconvenience this may have caused you. Please follow the below steps that may solve the issue:

The first step is to make sure the fast charging option is enabled

➊ Go to "Settings", then tap "Battery and device care"



➋ Tap “Battery”



➌ Tap “More battery settings”



➍ Tap the switch to activate "Fast charging", "Super fast charging" or "Fast wireless charging"

Next, make sure you use a suitable adapter and cable
Different types of chargers have varied power outputs. For optimal performance, we recommend using a Samsung authorized fast charging adapter.

 

Adaptive Fast Charging

- Samsung chargers that support 9V-1.67A (15W) power output show the ‘Adaptive Fast Charging’ text with a charging icon

 

Super Fast Charging

- Samsung chargers that support 9V-2.77A (25W), 15V-3A (45W), or 20V-2.25A (45W) power outputs show the ‘Super Fast Charging’ text with a charging icon

Note:

Samsung does not guarantee the compatibility of third-party chargers.

Follow these steps if your fast wireless charging is not working
For optimal performance, use a Samsung authorized fast wireless charging pad and/or the in-box adapter.

 

- Fast Charging 1.0 needs the adapter which supports above 15W power (max 9W charging power)

- Fast Charging 2.0 needs the adapter which supports above 25W power (max 15W charging power)

 

Some models may only work with the in-box adapter. For more information, please check the enclosed manual or the samsung.com product information when purchasing your device.
