No WiFi warns you through a notification when the Wi-Fi of your device is on, BUT you are NOT connected to the internet or to an access point. Disabling the Wi-Fi in this case avoids unnecessary draining of your battery.
CLICK on the notification to turn off your Wi-Fi quickly.
IMPORTANT NOTE for users with Android 3.1 : You have to launch the "No WiFi" App once after you have installed it. This is also necessary if you've stopped it manually in your app manager.
