    I've been using this coming up to two years
    It's a great app. I've had this on the Samsung Galaxy Samsung S then the S 2 and 3 now the Note 3. And on all devices I was getting 20 hours on aggressive setting. And that's with normal to heavy use. So yeah it is good. But there's still room for improvement. But other than that it is good if you're looking for longer battery life as simple as that.
  • Ash Darkfire
    Works rather well at lest with batter life it seems to extend. only issue is that i notice due to the fact its switching off the data radio and turning it on again as per the scheduled plan. the act of doing that seems to be messing with getting push notifications from other apps, sometimes not getting them to update at all sometimes. though it might be more of an issue with my devices and those apps rather than JD itself. I do rather like this app.
  • Josh Kay
    Really good app that could be great with one fix
    On my Galaxy Nexus it let's me get through a full day of moderate use while at work. Before installing the app I would typically plug my phone in several times a day and still be leaving the office with a red battery indicator. It also seems to keep the phone cooler as I don't seem to have a "hot pocket" anymore. Would have given 5 stars but seems to have issues with MMS.

    Battery saver!
    Just like the description says. I don't use ny phone while at work, but it would drain dead nearly everyday just sitting in my bag. Not anymore! Works great. I only have the free version so... fewer options. That's why the 4 stars instead of 5.
  • Rupinder Sra
    This needs to be verified by you.
    My Nexus7 started slowing down with heavy lag. Since I've always used JD free for many years & its the best for battery saving, I installed it on N7. Lo and behold the TAB is running fast. I HIGHLY RECOMMEND IT FOR UNROOTED Android devices. BTW its working fine on Nexus4 phone also.
  • Rizky Erizka
    Just great saving my battery in galaxy tab 2. I can get my tab stay alive for the whole day with normal use. Before using this it only last for 6 to 7 hours. But when you play games or other activity, it will help you no more... trust me. It not gonna save your battery when you play games alot haha.

    Juice Defender
    All I have to say is OMG. Finally I'm not a slave to the charger. Love the Samsung s3 but was always charging it. Since I got juice. Phone now can go a full day and a half On one charge with heavy surfing. Fb Twitter Istagram web podcasts Pandora Whatever and my battery lasts. Was gonna take the phone back until I found this little jewel. Thank u.
  • Jonquil Linnette
    One of the best apps ever to hit the app store!
    This has been my favorite battery saving app for years now, ever since gingerbread was the latest version of the Android OS. I've tried other top rated apps but I always end up coming back to this one because of its low profile/footprint and superior performance. Perhaps it's because it was originally designed at a time when Android ate cell phone batteries for breakfast. Either way you can't go wrong with it no matter what kind of cell phone you're using. Even older/cheaper phones can benefit from it.
  • A Google User
    Awesome must have app
    I went from my previous best minimal usage runtime of 40hrs to 50hrs after installing this app. That's just using the default balanced setting. It's great for extending battery life during idle/sleep time. Doesn't really help when the screen is on when you're doing stuff with it, then again nothing short of a high capacity battery can extend screen runtime. The best part is that it's free!

    So much better than Advanced Task Killer!
    I had advanced task killer, but it didn't help my battery at all. I would charge my phone all night and wake up go to school and by 3rd period my phone would be almost dead. But I noticed a big change when I got this, instead of 30% by 3rd period I still had 70%. Awesome app. :)
  • Alyssa Burdt
    I highly recommend it.
    I've downloaded this app in the past for my tablet, but ever since I've gotten a new phone, I decided to give it another shot. My phone's battery life would last up to 3 to 3 & a half hours (with the screen off most of the time because I'd be in school) and die before I got home. I charge it for whole nights, and I lose about 10% of battery life every 20 minutes it seems. So I downloaded this and set it on 'aggressive'. In about an hour, I noticed a HUGE difference in my phone's battery life! Get this app!

    Credit where credit is due
    I wasn't expecting a lot from this, but for a free app it's great. JuiceDefender has saved me a lot on battery life, so I thought I should return the favor by rating it. It's great for when you didn't charge your phone because you thought it had enough juice and the next day when you look at the battery find out you were wrong. It gets a few more hours out of it.
  • A Google User
    It works!
    Downloaded the free version about a week ago. Battery used to be almost dead after 12 hours of idle time with only a little data use here and there. Now after the same amount of time I still have 70%! I have only used balanced mode so it could improve my battery life even more if I changed the settings. Definitely a thumbs up!
  • Wayne Doucet
    This is an awesome add-in!
    I have never found an app that works so well at controlling my battery consumption! As we all know, smartphones consume a lot of battery power, especially if you like to actually use the features of your phone. And I like to use everything and all of the time! This app does a remarkable job of managing my downtime and maximizing my battery life! I love having the freedom of not having to remember to turn off wifi or Bluetooth. I can even leave GPS on without worrying. I highly recommend it!!!
  • Chris Odom Jr.
    Best by a long shot
    If you're looking for an app that is going to manage your apps, than this is not the app for you. Most battery consumption comes from your display, Bluetooth and data or WiFi connection. Juice defender is that kind of utility. With ultimate you can configure apps. You can set data or Wi-Fi to connect for certain apps, and you can set data and Wi-Fi to disconnect for other data hungry apps. Of all other battery utilities, this one doesn't touch your apps, and still saves more juice than the rest!!
  • Clement Te
    Best Battery Savings App
    i am always connected to the internet via LTE Mobile Data. Thus battery life is eaten up by it. using juicedefender, it really helps extend my phone's battery life if i dont open my unit often. by controlling and scheduling when internet connectivity must be activated. Balance profile already gives me significant savings and significantly longer charging intervals
  • Kevin Pustz
    Amazing, worth upgrading to Ultimate
    Juice Defender simply works. Upgrading to Ultimate was an awesome choice for me because it gave me way more control and way better battery life. I had a 1.35x battery life with Balanced and I know get 2.38x with my custom settings. I was skeptical at first, but I am now convinced. Pros: - Increased battery life - Easy to Use Cons: - Have to wait for data connection when turning on phone (takes about 5 seconds for me) - Updates from Facebook, Twitter, Email, etc do not come in right away
  • Bharathi Ponnusamy
    Awesome app
    Initially I was not aware of the importance of battery saving app. When I bought my S4, I just installed the juicedefender as per the rating & best app list and the battery life was good. The day comes when it has shown me the importance of this app. One of my Twitter friend has suggested that the aaa app is good. Hence I uninstalled the juicedefender and installed aaa. Then the battery has started draining like anything. Google play services is keep on running in the background and it is consuming more.

    Great App
    A great app, if you want to squeeze max out of your battery. My battery stats improved significantly over the past 3 days, so i decided to buy the JD Plus, since i wanted to tweak around with some apps. Sadly, it didn't work!! Though i enabled some apps, to be connected even after the screen is off, the software shut these apps down anyways. Probably you are good without the plus version, as its not working out!!
  • Guy Johnson
    Most Valuable App (Ultimate)
    Samsung Galaxy S3 went from 6hrs battery life to lasting all day. Increased battery life 2.32x! Turned off phone's auto brightness, set display to zero, then set JD so it adjusts brightness. Samsung Galaxy Note 3: Still working well. Keeps aggressive apps from killing my battery. UI helps me know what each setting does and if I need to use them.

    Works great but only with root and some tweaking
    In unrooted phones it is killed by the system. So 80% of time it's not working. However, with root, you can put it in RAM permanently and it will be always on. Currently it shows that it prolonged battery life x3.93 !!! With moderate use, I have 60% battery after 14 hours. Without the tweak it is almost useless. If you have root, go into build.prop and add line to keep it in RAM: sys.keep_app_1=com.latedroid.ultimatejuice If you don't have ultimate, I recommend it. If not, then change name accordingly.

    Pehle mai bht pareshaan rehta tha, meri bttry bht jaldi khatam ho jaati thi. Par jab se maine juicedefender use krna shuru kia, meri saari pareshaaniyaa durr ho gayi. Ab mai bohot khush hu. Aap bhi iss app ka laabh uthaaye. LOL Sry fr that drama abv, dis app is rlly useful tho. THUMSUP!!
  • Nikhil Agarkar
    Great little app!
    The basic mode in the few version has a trick for saving battery. It switches off 3G while the phone is not being used and turns it on every time you unlock the phone. And this does wonders to the battery life. The pro version has some additional features like location based auromatic Wi-Fi access. So basically, a must have app if you are not in the habit of using 3G data continuously, and are okay with periodic data sync.
  • A Google User
    Awesome lifesaver!
    I have a mytouch 4g and my battery life is very short,after installing the app my phone can literally last all day. I only have to charge it over night and my day starts at 5am to 10pm and my battery is still green,not even yellow! It is great bc I can still use media apps too wo slowing ir down or killing battery life.
  • A Google User
    Saved my phone!
    With this app, I can easily go all day on one charge with moderate use. Before, my phone would be at 20% or lower by halfway through the day if not sooner. There is no way I would have been able to go on a trip all day without having somewhere to plug in. Thanks Juice Defender!
  • Lionel Baboolal
    What can I Say?
    I love Juice Defender. I had other android apps that claimed to help me save battery life but they all failed. Some didn't even give accurate battery levels. My HTC EVO 4G drains even when I'm not using it. But with Juice Defender I can use my phone all day and the battery still has a lot of charge left. This app is ideal for extending your battery life and making sure you get the most out of your phone. It has a lot of great features that help manage battery usage.
  • Reaper Lament
    Finally a good battery saving app
    Out of all the apps I been through, this one is best . I like the setting that allows you to go from balanced to aggressive. Aggressive mode goes to extreme at about 15 percent (you can set at what percentage you want )It shuts down background processes unless otherwise told not. I been on 20, maybe 15 percent of battery before and have had my battery last nearly half the day and that's with general texting, calling and slight web surfing . Anyways I'm happy with it.
  • A Google User
    Best App. Download & read the info.
    I have tried every task killer/manager out there. Along with hrs spent learning how to close all background & system apps that constantly run. This app IS NOT A TASK KILLER but is much better at controlling all the apps & the constant stream of data & sticky broadcasts. By doing this & explaining quite clearly how to use it totally transforms your phone & stock & background processes. Plus it instantly makes battery LAST LONGER on simplest of settings. ALMOST DOUBE DAILY BATTERY POWER. BEST APP EVER 10*
  • A Google User
    I've never written a review about an app before, but Juice Defender is such a great app that I had to rate it. Prior to using Juice Defender, I would get around 12 hours of battery life from my SGII Skyrocket. After downloading Juice Defender and setting it to balanced, my phone has lasted for almost 28 hours and I still have 10% battery left. I can't imagine how much better battery life would be using either custom or more aggressive settings. I highly recommend this app.
  • A Google User
    Great app!
    I bought the Ultimate version of JD and I am happy with it. It does a very decent job keeping my hungry Droid RAZR up extra couple hours. You can easily get through a day with heavy usage and an hour of movie streaming everyday with one full charge. Thanks developers
  • A Google User
    Galaxy Skyrocket rooted,stock rom. JD (paid version) has at least doubled my available battery. With light use such as a couple phone calls, some minimal web browsing, a half dozen photos, etc...I have gotten as much as 22 hours on a charge with 15% still remaining. With heavier use I have gotten well over 14 hours. Great app, worth every penny.
