Determine Battery Status
The Windows CE GetSystemPowerStatusEx2 function can be called to return the SYSTEM_POWER_STATUS_EX2 structure. This structure contains important details about the power state of the device. Three of the most useful details in this structure are the ACLineStatus, BatteryFlag, and BatteryLifePercent members.
To produce accurate and complete information, device manufacturers must populate this data from their battery drivers, as shown in the following code:
PSYSTEM_POWER_STATUS_EX2 pwrstat=0;
if (!GetSystemPowerStatusEx2(pwrstat,sizeof(pwrstat),FALSE))
{
MessageBox(hWnd,_T("Couldn't get power state"),
_T("Error"),MB_OK);
}
else
{
// Extract the power status information you need.
}
