A descrição de Better Wifi On/Off

Better Wifi on/off aims at giving you the control of the Wifi state, optimizing your battery life without losing on user experience.
The app is free, fully featured with ads.
*What is the motivation behind controlling Wifi?*
On paper Wifi is less power hungry than 3G but... some apps behave differently when Wifi is on and the well known wlan_rx kernel wakelock is a symptom of wakeups caused by uncontrolled Wifi hotspots, the Wifi sleep policy is not working consistently and does solve all problems.
