Hmm, what I do is

#include <hwrmpowerstatesdkpskeys.h>
static TInt GetBatteryLevel()
{
	TInt batLevel = KErrNotFound;
	TInt err = 0;
	RProperty batProp;
	err = batProp.Get( KPSUidHWRMPowerState, KHWRMBatteryLevel, batLevel );
	LOG_FORMAT2( _L( "Batery: %d (%d)" ), batLevel, err );
	return batLevel;
}

Is this compatible with all devices?

[skumar_rao]

not sure about pre v9.x devices. But yes it works in all 3.x devices.

Sure there is, and A.A.M already gave the link in his post, it's the first one, pointing to CTelephony::GetBatteryInfo()

no that also give you levels.

[pavarang]

no that also give you levels.

It gives you levels, but in percentage, as asked: 14,28,42,57,71,85,100....

Read between the lines (or how to say). It is pretty sure that Ashraf Fawzy is able to divide two numbers (1/7, 2/7, ... 7/7), and multiply them by 100 to have a percentage (100/7 = ~14, 200/7 = ~28, ... 700/7=100). He needs a finer resolution, that is what this thread is about.

Hello Wizard_hu_,

Is there a way to get battery percentage / level after reaching (1 Bar = 14.28%)?

I noticed that Nokia Battery Monitor application in OVI Store can get the percentage down to 3%.


I'm using CTelephony but in only notify me down to 14.28%, down that it notify me, but with the same value which is 14.28


Is there any function that is used on Symbian^3 devices that achieve what I want?


Best regards.

AFAIK no public API's are available to get that much accurate battery status.

[ashraf fawzy]

Thank you savaj for your answer,

So Nokia keeps some of juicy API's to itself to use it in its applications as Battery Monitor

Someone else posed the same question on the russian forum:
http://www.developer.nokia.com/Commu...9-%D0%B2-Nokia
and the answer was CHWRMPower for newer devices (no 3rd, see #7)

Hmm.. CHWRMPower::GetBatteryInfo() might do your job at-least in Symbian^3.

Check how much accurate battery status will return following code.

TInt remainingBattery;
TRequestStatus status;
TBatteryConsuptionData batterydata;
iPower->GetBatteryInfo( status, batterydata );
User::WaitForRequest( status );
remainingBattery = batterydata.iRemainingPercentageCapacity;
