"Long live the battery"

Reviewed by / Jul 01, 2011

JuiceDefender Plus is an app that helps you out with saving battery by managing data, cpu and connectivity

JuiceDefender Ultimate is the full paid version of JuiceDefender ($4.99) which contains all the extra features that brough JuiceDefender Plus and adds: Extreme Profile, Timeout control, CPU frequency scaling, new settings for APN control. High-customizable.

There are three components that drains battery most: connectivity (3G/4G/WiFi), CPU speed and mobile data (apps, processes). JuiceDefender wants to give you comprehensive control over these components in order to save some battery.

First, it contains 5 preset profiles (from default mode to full customization): balanced, agressive, extreme, advanced, customized). By that way, you can set when to enable/disable 3G/4G/WiFi, set CPU speed to adapt it to the needs of each app or processes and manage them to your liking (task killing).

Thus, it contains mobile data toggle automation, as well as connectivity toggle automation (APN), battery consumption optimization (when screen off, battery under threshold, etc.), smart brightness control and a full activity log of all of this.

But what we've really found interesting are two features: "Comprehensive Connectivity Scheduling" and "CPU scaling when phone is idle". First one, will enable/disable connectivity automatically, when you think you're going to need it. Second feature, decreases CPU speed not to waste battery when isn't needed.

JuiceDefender Plus has been developed by LateDroid, an experienced developer focused on the extension of battery life by controlling system parameters in a understandable way for amateur users.

It's true that the main catch of our smartphones is their battery-life. For that reason, we consider JuiceDefender a must have since it truly helps us to extend battery life.

    One of the few apps I absolutely recommend to everyone. Breathed new life into my aging Droid 4. Extended the battery life by a significant amount while using the "Aggressive" setting. Would give my first born for this app.

    I have the SIII. I bought the ultimate to configure apps and control my data. However it doesn't work, instead whatever you pick enable, enable/screen or disable the app does not connect to the internet. Just use the free portion, waste of money.
