Basics
Fast charging
The device has a built-in fast charging feature. You can charge the battery more quickly while
the device or its screen is turned off.
Increasing the charging speed
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 icon appears on the screen.
If the fast charging feature is not activated, launch the Settings app, tap Device care →
Battery → → Settings, and then tap the Fast cable charging switch to activate it.
• 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.
