Who’d have thought, ten years ago, that today we would be navigating our way round cities, listening to music, and catching up on last night’s TV and the latest news — all through our phones?

Luckily, there is a (partial) solution for this: JuiceDefender. This program helps preserve and extend your Android phone’s battery life by selectively turning off certain functions, such as mobile Internet (which hogs power more than anything) and WiFi, meaning you can use your phone for much longer periods between charges.
This is certainly a welcome application for all smartphone users. Let’s take a closer look at the application and its features and see what it can do for your phone’s battery life.
We’ve featured a couple of articles helping your battery last longer: some general tips, and a post about SetCPU. Maintaining charge is a concern; listening to music, watching videos, playing games, surfing the web, and, er, making phone calls can all drain the battery pretty quickly, and that’s not even thinking about background tasks like automatically syncing your emails.
I usually charge my phone to full power right before I go to bed, and then give it another charge while I’m working during the day. How about you? Vote in the poll to let us know!
Recently, author Darren Meehan covered some great ways to improve the battery life of your Android phone. Today, we’re going to take a look at the app SetCPU. You will need to have root access to your device in order to run this application.
