Location-based services can make wasteful consumption of battery run time when run in the background. That is why the Android using the controls that are specific to the use of a GPS chip in every device. There are several widgets that you can use to enable or disable the GPS feature of the home menu screen. We recommend that you enable the GPS just as you need (when navigating or open Google Maps) to avoid wasteful consumption of battery.

To turn the GPS on Android device, press the Home button so that you are on the home screen.
From the contextual menu on the home screen, select Settings.
Scroll down the Settings list and find settings for Location.
Here you have two choices to make the GPS settings.
Here are two options to set the GPS on Android devices. First Use of wireless networks, which will enable the ability to use your GPS device BTS towers or wifi network to determine the location (A-GPS: Assisted Global Positioning System, also read about A-GPS on this link) with an accuracy that depends on the presence of BTS and the wifi network. This option does not consume battery excessively.
Use the second option is the first GPS satellites to activate the GPS chip. This option is more accurate because of the location based on GPS satellites (like a real GPS device) but resulted in wasteful consumption of battery.
