Worried about Android battery life? You aren't alone. With the right tools on your smartphone, though, you can make the most of your charge without having to constantly futz with settings.
An app called JuiceDefender helps you automate the optimization of your smartphone's power configuration. The program lets you define detailed parameters to govern how and when your device uses common battery-zapping functions. Set it up once, and you'll never have to think about that stuff again.
JuiceDefender can disable background data processing when your screen is off, turn off your smartphone's Wi-Fi when you aren't near a known network, scale down system processes during certain hours of the day, and much more. All put together, its automated adjustments can make a noticeable difference in your phone's daily stamina.
JuiceDefender is free. An plug-in called UltimateJuice adds a handful of extra options into the program; it costs $5.
