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.

I have never crapped so hard in my own diaper as i did with this app. I notice that phlegm and puke now flow like rivers. A drunk cow could never part

Free version is a waste of space, doesn't do anything. Only thing that it does that you can't do yourself is only available on rooted phones. Stupid.

Awesome! My battery usually drains fast & I need to charge throughout the day b/c of frequent internet use. Over 1/2 battery life left!!! *Vibrant*

Great app. I did not give it 5 stars because you only get minimal features until you upgade to paid version - then you get the good stuff.

Awesome app.... love it! could you add a feature so when streamin pandora or other music the data block doesnt occur when the screen goes dark?
Great app. Saves a lot of juice. Lags the phone sometimes, but overall very good. Good gui. Galaxy S vibrant, rooted.

Battery life extended immensely on MT3G. Seemed to suck up some memory, but all is well after installing recommended task killer.

Awesome battery results so far. Two to three times previous run time. HTC Incredible.
