Galaxy Note 4 - How does fast charging works and how does it increase the charging speed?

Last Update date : 2016.04.30

To increase the charging speed,

turn the device or its screen off when you charge the battery.

 

- While charging the battery and while the device is switched off,

the charge icon  icon appears on the screen.

 

- While charging the battery when the device's screen is turned on,

a pop up window appears requesting you to turn the screen of.

Turn off the screen to increase the charging speed.

Similarly, Please note you cannot use the built-in fast charging feature

when you charge the battery using a standard battery charger.

 

Similarly, When using this specific fast charger with previous models,

it just works identically with normal charging because fast charging need

to have built-in fast charging feature.

 

And 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.
