JuiceDefender Receives Significant Upgrade

There is great news for all of you Android users seeking improved battery life: JuiceDefender has ditched its complicated user interface for a sleek, intuitive system of sliding tiles. Also included with the update is the ability to backup your settings.

JuiceDefender is a capable battery manager application that gives you total control of your phone’s radios, allowing you to toggle 2G, 3G and wifi on and off in a number of pre-set situations. For example, you can choose to have JuiceDefender automatically enable wifi for a few seconds before connecting to 3G to determine if an open network is available, and then disable wifi if it cannot connect to an open network. Another example is the ability to enable 3G data every five minutes. This allows your phone to receive emails and other data without being constantly connected. JuiceDefender would then disable 3G data once data traffic dropped below a number that you choose (i.e., 5KB/5sec). There are a number of additional settings that result to improved battery life.

I have used the application on my HTC EVO 4G for the past couple of months and have noticed a significant improvement in my phone’s battery life. If you would like to see similar results, scan the QR code at the bottom of the article or search for JuiceDefender in the Android Market. While JuiceDefender is free, a premium add-on called UltimateJuice costs approximately $5. UltimateJuice features nifty extras such as location-aware wifi management. Latedroid, the creator of JuiceDefender, tipped us on an upcoming discount to UltimateJuice that will occur sometime in the next few weeks to celebrate JuiceDefender’s 1 millionth download.

  • After the most recent update it causes my Milestone to randomly decide to kill the haptic feedback and not accept any connections (wifi or 3g) or phone calls, until the phone is restarted.

    It’s likely a strange issue caused by an incompatibility between juice defender and the rom i’m using, so I imagine it’s not a widespread bug or anything, but sadly it has forced me to stop using juice defender for now…which is really aggravating, because it is pure awesomeness.

  • I use Battery snap to monitor my battery life history and it is quite nice. It has many widgets, customizable, and a nice history viewer as well as life and recharge time estimation. But i agree that Juice defender is not bad…

    The problem that I had with Juice Defender in the past was that every time that it re-enabled 3G it also forced a refresh of all my accounts. Repeated forced refreshes essentially offset any battery savings that would have resulted from turning off the 3G radio periodically. Does anyone know if this has been fixed?

  • I’m totally glad with it, been using my juice defender for 2 weeks and it has maximized my battery with an overall of 1.4x. 🙂

  • After trying it on a Milestone I decided on Green Power. Not as much confirations, but much more stable.

  • I use it on my EVO with the 3500mah battery. after 17 hours off the charger, I am at about 85% charged.. my green battery button is at 100 percent..

    My wifes standard issue evo had shown similar success plent of battery come the end of the day…

    i hope to see how long the seidio 3500 mah goes without charging..

    No lockups or bugs.. thinking of getting the ultimate version..
