How to use Ti.Geolocation safely for battery?

I develop an application that send coordinates to server every 10 minutes. When i start my app battery level drop for 10% per hour. I don't need in best accuracy but i need to send coordinates every 10-15 minutes more safely for battery. That's how i do it in my iOS background service:

if (Ti.App.Properties.getBool("gpsInBackground", true)) {
            Ti.Geolocation.setAccuracy(Ti.Geolocation.ACCURACY_HIGH);
        }
        else {
            Ti.Geolocation.setAccuracy(Ti.Geolocation.ACCURACY_LOW);
        }
 
        try {
            Ti.Geolocation.getCurrentPosition(function(e) {
                sendCoordinateToServer(e);
            });
        }
        catch(e) {
            Ti.API.log(e);
        }

But there is no difference between Ti.Geolocation.ACCURACY_HIGH and Ti.Geolocation.ACCURACY_LOW for battery. Independent from this parameter, my battery's level going down for 8-10% per hour.

Is there a way to complete my task more safely for battery?
