The largest battery hog, by far, is GPS. The second largest battery hog is using the phone as a phone. The third largest battery hog is probably screen brightness sat hi. The fourth largest battery hog is probably Wi-Fi. However, this is only the case when Wi-Fi is actively maintaining a connection. If 3G, for G, or LTE is the connection instead, that becomes the similar large battery drain. Active Bluetooth is probably fifth. In active Bluetooth that is turned on drains 1% to 3% per hour, so is a minimal battery drain.
