The only way to really know how much battery is being used is to have hardware that measures actual current during various operations in your app.
And that tells you about battery use for *that* device, which can have fairly different characteristics from another device. So I would suggest that instead of getting lost in such details, you look at the general rules that people write about how to reduce battery use -- hold wake locks as little as possible, use the CPU as little as possible, etc. You can find out these kinds of details about your app with "adb shell dumpsys batteryinfo".
