AutoDisabler (aka your battery’s best friend) automatically disables WiFi and/or Bluetooth after a user specified period of connection inactivity. What does this mean? When you disconnect from a WiFi network (or Bluetooth device) your device will automatically turn off WiFi (or Bluetooth) after a designated amount of time (or immediately) unless you reconnect to WiFi or a Bluetooth device during the delay period. This is a great way to save battery life by automatically disabling battery-draining radios when they are truly not needed.
