Battery$ allows you to save battery without having a rooted device! When your is locked, your WiFi is disabled, but when you unlock your phone... Tada! Your WiFi is enabled once again. But wait! There's more! (Duh, that would be boring then)
If you are connected to your data network AND connected to wifi, your phone will vibrate and a message will appear asking you to disable mobile data. The root edition will flat out do this for you! (It will also do more features aswell)
