JuiceDefender - battery saver

JuiceDefender - battery saver

Oh, dying batteries. You are the bane of my existence. But whereas many users will resort to better hardware (or even replacement batteries), my motto is: let the software take care of energy vampires for you. On that note, let's take a closer look at JuiceDefender - battery saver.

As mentioned in the intro, I'm not the type of user who will invest in several external batteries. I prefer to let an app suss out which are the main energy culprits and then act according on this information.

JuiceDefender - battery saver is an app that is meant to provide your Android device with more – or rather longer lasting – battery power by trimming some excess fat, i.e. device settings. Android has a few innate settings that help reduce pointless energy consumption, but JuiceDefender - battery saver does have a few clever new tricks up its sleeve.

For instance, one option is to cut all internet connections whenever the device goes into standby-mode. Connections are reestablished as soon as the display becomes active again. Another option is to cut internet connection but check for incoming emails etc. at 15 min intervals.

Every user can compose the settings profile that is best suited to his or her needs. To do so, hit the advanced settings feature and start making your own configurations. Every single setting comes with a detailed explanation that feels personable and all of these text were obviously made with a love for detail and user friendliness.

Bottom line:

JuiceDefender - battery saver is a thoughtfully made app that does it's job very well. You can take over the pre-settings or adapt them to suit your user behaviour and preferences, but either way the battery will last longer.


Screen & Controls

JuiceDefender - battery saver comes with a helpful intro text. The UI is not exactly pretty but it does what it's meant to do.


Speed & Stability

JuiceDefender - battery saver performed very smoothly throughout our test runs.


Price/Performance Ratio

JuiceDefender - battery saver is free of charge and can be found in both the App Center and Play Store. I find that supporting the developers' excellent work and getting the high useful extra features is well worth the EUR1.99 for the pro version, as well as the EUR4.99 for the ultimate version.
