When charging withFast Charger on the Note 4 , it doesn’t seem to be charged rapidly. When does the Fast Charging feature work and How can I increase the fast charging speed of Note 4 ?

Last Update date : 2014.10.07


To increase the charging speed, turn the device or its screen off when you charge the battery.

• While charging the battery when the device is turned off, the lightning 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 off. 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.
