Pre-Symbian OS v9 solution
These solutions can be used in S60 1st and 2nd Edition devices.
#include <saclient.h>
Link against: sysagt.lib
...
RSystemAgent systemAgent;
User::LeaveIfError(systemAgent.Connect());
TInt strength = systemAgent.GetState(KUidBatteryStrength);
systemAgent.Close();
It is also possible to read battery status using HAL:
// Remember to link against hal.lib
#include <hal_data.h>
#include <hal.h>
...
TInt battStatus = 0;
TInt result = HAL::Get(HALData::EPowerBatteryStatus, battStatus);
Post v9 solution
The article below describes the solution that should be used for S60 3rd Edition and later devices.
