Longer battery life in your Android
Do your Android discharge just at those moments when you need it most?
Take control of your phone's battery consumption by using the app JuiceDefender. With a single touch you disable the most battery consuming apps and functions on the phone.
Choose from a preset function including disable 3G/4G and WiFi, or customize your own settings and determine which of your apps will be temporarily closed down by a button in the app. JuiceDefender is free and can be downloaded at http://www.juicedefender.com
