It is general compliant that android consumes lot of battery. There are few things you can do to save the battery.

Step5: Turn off Location Services when not in use. Reason: The aGPS connects to the satellite via your WIFI network or through your mobile network. This process also eats lot of battery. Turn off all the option. When ever you want to use any map oriented service you can turn on this option.
