Save Android battery life with JuiceDefender

As usual, I was talking up Android with some iPhone-toting friends this weekend. We sat around and compared phones, and after we all talked about what we loved about our devices, the conversation turned to what we didn’t like. I’ll spare you their complaints. Mine, as expected, was about battery life. I’ve done plenty to help conserve battery on my Nexus, but I still don’t get a full day out of it if I use frequently. Thankfully there was another Android user present, and he turned me onto JuiceDefender.


The app’s premise is pretty simple. A lot of battery life is lost when your device checks for updates via the data connection. JuiceDefender sets a schedule so that your handset checks the network only so often. That way it reduces battery use, since it’s not constantly checking for new Facebook and Twitter updates. In that way it works best when you’re just at your desk, doing what you do on your computer. There’s little need for a constant connection on your smartphone at that point. That’s where JuiceDefender steps in and preserves your battery life.

Once you download JuiceDefender you’ll go through a quick setup process that will allow the app to optimize for your device. After that you click the Enabled button, and you’re ready to start configuring the settings. I’ve left it on default, since that works well enough. But here’s a quick rundown:

Schedule: This determines how often your device will check the network. The default is for one minute every 15 minutes, which is just fine by me. That’s 14 minutes in which my device consumes very little battery.

Battery: Set the battery level at which data will be automatically disabled. The default is 15 percent.

Traffic: Here you set the level of traffic that keeps data enabled. By default JuiceDefender will keep your data connection active if you’re transferring more than 50KB every 15 seconds. You can set both the data amount and the time.

Screen: You can set the app to turn on the data connection only after you unlock the device. This way you can click the power button to see the time without turning back on data.
It's free. More detail and download here
