Accurate battery status

[Itixis]

Hello developers.
How I can obtain accurate battery status (for example, 98.98 instead of 99%)? Do you know such methods? QSystemDeviceInfo class provides batteryLevel, but value of batteryLevel isn't accurate, particularly for my futher application.

probably you can make formula for that accuracy and use in your coding, otherwise QSystemDeviceInfo class provides the accuracy as you know.

How could any formula works until and unless you can not get exact percentage of battery status? Let us know if yo have formula in your mind.

@Itixis:
AFAIK, you can not get that much accuracy even using Symbian API's (i.e. CTelephony and HAL)

Why are battery statuses difference in Nokia Battery Monitor and in my application (based on QSystemDeviceInfo::batteryLevel)? E. g. battery status in Nokia Battery Monitor is 92%, and battery status in my application is 100. Do you know, why it's so?

Following code (symbian) might gives you accurate battery status on Symbian^3 devices .

TInt remainingBattery;
TRequestStatus& status;
TBatteryConsuptionData batterydata;
iPower->GetBatteryInfo( status, batterydata ); // iPower is of type CHWRMPower
User::WaitForRequest( status );
remainingBattery = batterydata.iRemainingPercentageCapacity;

Thanks, savaj.
I will try to use this sample in my code.
