A free program for Android, by droidplant.

If you are tired of always having to enable your WiFi/WLAN when you need it, and then have to disable it again when you don’t need it anymore, this is the app for you.

Wifi Power Saver is capable of automatically turning off your WiFi/WLAN when no network is available. This means that you don’t need to remember to turn it off, you can just leave it on and the app will turn it off for you.

When you connect to a network again, the app will automatically turn it on for you.

This app can be very useful for those who are always on the go, but want to save battery power at all times.
