How can we calculate/ to know, how much battery li

Question

Here my question is, can we identify, how much battery life my android application is utilising. Because I developed an app based on GPS as well as network, service, broadcast receivers, so I have battery drain problem, so first of all i want to know that how much battery percentage is my application using. Any idea. Thanks in advance.

It is difficult to say exactly how much battery life is used by specific application. But, you can refer following links which may give you a little idea.

Programmatically, you would need to maintain BatteryManager logs for your application in your app itself.

Regarding,battery uses of GPS,network, service, broadcast receivers etc. it depends on how you implement it. Eg:-Use passive providers rather than GPS or network providers also use setinexactrepeating method for alarm manager, etc.
