measuing the amount of energy comsumed in a function call

[chenrs]

hi guys

I wonder if there's such API that I can use to measure the amount of battery energy comsumed in a function, such as:

begBattery = SomeAPI();
// do something
endBattery = SomeAPI();
batteryConsumed = endBattery - begBattery;

I found there's a API called GetBatteryInfo() of CTelephony, but the problem with this API is that its precision is too low, so I wonder if there's some better API.

Thanks in advance.

You can check Nokia Energy Profiler, it also has some API as I know. Library above, Tools and downloads, Find more tools.
