Precautions when using Fast Charging Feature

• While charging, you cannot activate or deactivate this feature.

• You cannot use the built-in fast charging feature when you charge the battery using a standard battery charger.

• If the device heats up or the ambient air temperature rises, the charging speed may decrease automatically. This is a normal operating condition to prevent damage to the device.

• Check the USB cable is pushed tightly into the charger. It needs to be pushed all the way in. If not so, fast charging feature do not work and very low capacity for charging will be supplied. Accordingly, the charging speed will decrease and time to charge the battery fully will also take much longer.

Power up without being tied down. When your battery's drained, quick and convenient wireless charging gets your Galaxy Mobile back to 100% without needing to plug it in.

Please Note: Fast wireless charging is automatically activated when you use a fast wireless charger. 

To charge your device wirelessly, connect the charging stand's wall charger into a power outlet, and place your phone on the charging stand with the screen facing up. Next, connect the other end of the charger into the back of the charging stand's base. The indicator light on the base will flash blue, green, and cyan when you first connect the cable. Try moving your device around on the wireless charger to establish the strongest connection. 


If you're having trouble wirelessly charging it's recommended to remove any cases and covers from your device.
