User reviews of JuiceDefender - battery saver
cool apps
Mar 9, 2013
It can save your battery life IF you can figure out how to get the settings just right. It is not easy to use. One incorrect setting can drain your battery. It does not clearly explain what your options are for each setting. I've had this over a year, changed settings numerous times, and am still frustrated with how it randomly shuts off my data delivery. I only recommend this if you have superior knowledge of the inner workings of a cell phone!

Perfect!.One of the rare applications I actually bought it.

changed my battery life from 8 hours to 6 hours

I'm quite happy to recommend this free app, I liked it so much I bought ULTIMATE. Like anything that is going to save you a lot of power you will need to make minimal adjustments, for example the app may have switched WIFI offso turn it back on if you need it.

Great battery saver Has saved my battery many times and makes a huge difference to how long I can make a charge last. Can't believe how much of it is free!

Pretty much abandonware Used to help so much, but times have changed, and this app hasn't.

Great battery saver app! Battery charge last much longer now because unused apps running in the background are turned off.

Doesn't work with android 5 After the lollipop update juice defender has stopped working, much to my regret. I love the app, but if you could maybe help me out and determine why it isn't working, if it's you or android, that'd be great!
