Use Wi-Fi to determine your location to save battery
Previously with Android, determining your location was based almost solely on GPS, which consumes a fair amount of battery life. Android 4.4 now comes with three modes for this functionality.
High accuracy uses GPS, Wi-Fi and mobile network signal to get a fix on where you are, while Device Only relies totally on GPS. In the middle there is Battery Saving mode, which abandons GPS and uses Wi-Fi and your mobile network – amazingly, this is still pretty precise, and doesn’t drink as much juice. Go to Settings > Location > Mode to pick the one that suits you.
