JuiceDefender – Battery Saver is a powerful, yet easy to use Battery Manager App.
It extends battery life by intelligently managing the battery-draining components of Android devices, like 3G/4G connectivity and WiFi.

JuiceDefender is also fully customizable through a clean and intuitive user interface. Once configured JuiceDefender runs by itself, improving battery life in a fully automated manner.
With JuiceDefender – Battery Saver you can easily manage your Mobile Data, WiFi and CPU speed, you can keep power consumption under control (e.g. disabling connectivity when the battery runs low), schedule regular Synchronization events, enable or disable connectivity for specific apps, auto-toggle WiFi depending on your location, and much more.
