My Samsung Captivate Android phone keeps searching for WiFi when I’m not at home and keeps draining my battery. Some times the battery does not even last for the whole day. So I kept searching for app that would use my location and turn off WiFi when I’m not at home.
I found WiFi@home app in the android market, where you can set your home location and it would turn off WiFi when you go out of your home. It would automatically turn on WiFi when you reach home. This would save your battery.
