JuiceDefender is an Android battery saving app classic

Developer: LatedroidDownload: Android
Category: Battery lifePrice: Free

Today, we're introducing you to a battery saving classic - meet Juice Defender. It has been on the market since 2011 or so, and it has had over 10 million downloads while enjoying user interest 'till this very day! 

So, what can it do for you? Well, the app relies on smart functions that automatically manage Android's battery draining components, such as data and Wi-Fi connectivity. Preset modes make it easy and simple to score extra battery life, but if you want to get at the heart of it all, JuiceDefender is completely customizable. 

The app integrates with the power and shortcut widgets you have installed, although your mileage may vary. Stuff like managing mobile data, Wi-Fi, CPU speed, scheduling regular sync events, enabling and disabling connectivity for specific apps lets you get the most out of your device's battery.

JuiceDefender's free version contains five user profiles, home screen battery widgets, location-aware WiFi control, comprehensive connectivity scheduling, a full activity log, and more. If you need any of the extended functionality, feel free to upgrade to the paid JD Plus or Ultimate.

I don't need such type of apps, I've my own personal settings. I think such apps are more power consuming than saving.

It does actually cost me more juice than it saves. I haven't used it in a year or two. I originally paid for the app, and it did help when 4g was still new. Now it is a battery killer.

Correct me if i am wrong but this app was not updated since 2011/2012...design wyse it looks horrible - where is the "evolved" Android design language???...does app like this deserve to be mentioned several times on your site here? When that developer is able to pay you for a thread - they┬┤d better move their a..es and work on the app to look better and be better.... TASKER is cheaper and more powerfull....

It does stuff you can manually do yourself in the phones settings, all while running as a background process, leaching resources and using battery life. Bravo.

I've tried this app on a number of phones through the years. I always uninstall it after a couple of weeks because at best it made no difference, at worst it decreased battery life, albeit slightly.

This app takes me back aways. I remember trying juice defender twice. First time I installed briefly on my My Touch 4g & again on my Galaxy Nexus. Both times I uninstalled because it drained my battery

Had this app (the paid "ultimate") since late 2011. Agree it's ugly, cluttered, chaotic designed, tuff to set correct, not updated, but, in combination with Tasker (since Kitkat to toggle airplane mode), there is still no competitor. With lollipop it force closes trying to switch Data on/off (by changing the APN), so I had to seek for an alternative, found GreenPower Premium, but it is not as good

GUYS, you have posted a story within the past week about how battery savers are not any better for your phone than anything. WHY do we still get these kinds of posts? So contradictory.

TI'm using battery doctor. Not really sure if it helps or not. But yes just a couple of days ago you posted an interesting article how these apps are worthless. Is there a general editor or are all the journalists posting whatever they like. And so what is your stance on this issue?????????????????????????????????????????????​??????????????????????????

Some folks don't seem to appreciate the difference between task killers and battery extenders. Juice defender was great. I only moved from it to greenify and one power guard when wake locks were an issue for my ROM at the time. Maybe it's time to experiment again.
