What is fast charging and how do I use it with my Galaxy S6 / S6 edge?

About Fast Charging

The Galaxy S6 / S6 edge device has a built-in fast charging feature. You can use this feature to charge the battery faster while the device or its screen is turned off.


Fast charging uses battery charging technology that charges the battery faster by increasing the charging power. The device supports Samsung’s Adaptive fast charging feature and Qualcomm Quick Charge 2.0.


To use Fast charging on your device, connect it to a battery charger that supports Adaptive fast charging or Quick Charge 2.0.

Increasing the charging speed

To use the Fast Charging feature, your phone needs to have the screen off or needs to be powered down when you charge the battery.


To increase the charging speed, charge your device in 'Flight Mode' 


While charging the battery, it will be indicated in the notification panel and on the battery icon in the top right corner of your phone.


You can check the remaining charge time on the screen. The actual remaining time may vary depending on the charging conditions.


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 will happen to prevent damage to the device.
