JuiceDefender - Battery Saver is a powerful yet easy to use power manager app specifically designed to extend the battery life of your Android device. Packed with smart functions, it automatically and transparently manages the most battery draining components, like 3G/4G connectivity and WiFi.

The _preset modes_ are the perfect way to gain precious hours of battery life - literally as easy as one tap!
JuiceDefender also allows _complete customization_ through a clean and intuitive user interface; and once configured it runs by itself, improving battery life in a fully automated manner.
Finally, it _integrates seamlessly_ with power control widgets and shortcuts, without interfering with manual settings.

With JuiceDefender - Battery Saver you can easily manage 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.
