Use case

The application could notify the user when the battery is low.

Source file

//necessary library
LIBRARY	        HAL.LIB

//necessary header file
#include <HAL.h>
#include <hal_data.h>
 
TInt powerBatteryStatus;
//retrieve EPowerBatteryStatus value
HAL::Get( HALData::EPowerBatteryStatus, powerBatteryStatus );
 
if(powerBatteryStatus == HALData::EPowerBatteryStatus_Zero)
   {
   //battery status is zero.
   //performing corresponding operation
   ....
   }
else if(powerBatteryStatus == HALData::EPowerBatteryStatus_Low)
{
   //battery status is low.
   //performing corresponding operation
   ....
}              
else if(powerBatteryStatus == HALData::EPowerBatteryStatus_Good)
{
   //battery status is good.
   //performing corresponding operation
   ....
 
}
