"Long live the battery"

Reviewed by / Jul 01, 2011

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

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 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.

    my galaxy s4 on 4.4.2 disables my data, and doesnt reconnect it. frustrating bug, only way to fix this is by restarting my phone. please fix this. other than that this app turned my galaxy s4 into a phone that i can really rely on.
