JuiceDefender and Power saving on GS3

    I have JuiceDefender installed and running, and I wonder how this works when my GS3's "Power saving" mode is active. It seems their functionality is mutually exclusive, with JD turning off the antenna when the screen is off, and the default Power saver just limiting CPU performance and whatnot.

    Has anyone tried this combination? Did they notice a difference when using one and/or the other?

    Also, is it worth buying the paid versions of Juice Defender, and if so, should I go for Ultimate or stick with Plus?

    Generally speaking, most of the apps touted as battery-savers will actually do the opposite. You're better off just using the available utilities already in Android, and changing settings to minimize battery use (turn down display brightness and reduce timeout period, turn off unneeded radios, disabling background data for apps, etc).

    Really? I've heard *many* people speak high praise of JuiceDefender, with many people claiming a significant increase in battery longevity.

    You should know such apps do deny other legitimate apps for waking up device to do it's work like say alert pop-up etc. And most users will complain why that legitimate app cannot do it's functions where they forget they turn on such power-saving apps in the background which interfere other legitimate apps from working properly.

    I tried JD ultimate for a long time and never got much from it.
    I also tried Greenpower.

    The above comments are spot on. You want a fine balance between making it actual work to use the danged thing and yet still be effective.
    This app is intuitive, you know what switches are on and which are off. Easy to flip if you need.
    And what kicks my behind is my battery lasts, quite literally, for days now.

    I have juice defender ultimate on my rooted razr running 4.0.4 and it helps tremendously.

    I for one have used JD on all my phones ever since I've been in the smart phone game and I can say that JD is one that actually does work. After doing many many tests, JD has proven that it does save battery. The numbers don't lie. So now I CAN'T NOT use it. I turn it off and my battery just plummets to the ground. If it's set up right, it WILL save you battery though that's a fact. Certain features in the app that I feel are not needed like the auto brightness and settings for nighttime and busy times are ones that will actually eat up your battery. The app will show up in your battery usage when otherwise it doesn't. SO, as long as the app is set up correctly it will save you battery usage.

    Just wanted to share my thoughts. Not trying to disregard anyone's opinions on the matter. :D

    The best battery saver is between your ears - learning to setup your device properly. Android already includes what you need.

    The only so-called 'battery saver' I've ever found worthwhile is Y5 (or similar) which is really a simple location-based WiFi switch.

    Juice Defender is kinda poor and should be avoided. It may use more than it saves, interfere with operation, etc. If you think it helps then you should check your Android configuration. That said, if you have an unusual usage case where JD offers particular options you need that are not available in Android setup it *might* have some benefit. Such cases are probably rare.

    I think there is a confusion here about what is a battery saver, and what is a task killer.
    My post history is open to scrutiny and I have often condemned task killers and provided authoritative websites as citations.

    Juice Defender is not a task killer. It prevents certain functions of the phone from operating when you are not actively using the phone. In particular, Sync is decreased, so you won't always see new emails unless you manually refresh in the app, for example.

    I can assure you that this tech-savvy, but non-IT, person can handle "setting up" and managing an Android phone. But there's something majorly wrong when trying to explain to noobies about checking settings and running apps, and when even I can't keep Google Maps from consuming 47% of my battery for no good reason. I don't believe that people should be required to actively manage their smartphones multiple times a day. If they do, it's a failure of the technology and no one should be faulted for not wanted to do that.

    I started using JD on my Rezound as a last ditch effort to not be stranded without battery power. It has had a positive, and marked, affect on my battery life. I suspect that those that are against JD haven't actually used it.

    well, as a matter of fact all these programs try to reduce the battery consumption when the phone is idle, but they don't affect the battery consumption during the active using of the phone and probably make it worse, if your idle battery consumption without battery savers is acceptable you simply don't need them.

    I spend zero time per day 'managing' my phone. Android does an excellent job with no help from me or JD.

    I actually tried to use JD for about 2 weeks. According to it, i got 1.1x the battery life (barely an improvement at all) and I couldn't feel a difference, so I uninstalled it. I think that newer versions of android (i'm running 4.0.4) are actually a lot more power efficient than the older ones just by themselves.

    You can disable jd when you're actively using your device. There are endless custom settings that you can setup to work best with how you use your device.
    I know the battery life in my razr has improved significantly since I began using jd ultimate.

    Another thing people forget is when we have smartphones that are advancing, things will tend to eat up more battery . Respectively, so does battery technology but not to the point where it will completely negate it. I , honestly, hate HATE downloading battery saving apps and watching it. Restricting background data to sync every hour? why do I even have a damn smartphone then? I have a rooted/OC's/UV'd Note 2 that usually lasts the whole day on a charge with pretty good use. Another option, is to keep a spare battery in your car and swap it out (if you are able to swap batt's quickly)

    When I first got the phone. no root or anything with a couple of apps. The battery life on stock jelly bean was AMAZING. When I started to pile up the add-ons, it decreased.

    Battery-saver apps aren't going to be for everyone's lifestyle (clearly not for yours). But for many (not you) users, a smartphone's data is particularly handy when the screen is off and particularly not as handy when the screen is off.

    The link in your sig, I have a couple of questions about.

    So, essentially, data is turned off when your screen is for >15 mins? And is enabled once you unlock your screen? And, is that application named tasker?

    What are you sacrificing using this?

    Even that Tasker profile is for only particular lifestyles. Again, if you real-time notifications on everything with absolutely no lag ever, then you should never turn your data off.

    If, however, you want your data on when you are actually using your phone, and then only occasionally synced in the background when you're not using your phone, something like Juice Defender is good.

    Tasker isn't this, though. Tasker allows you to do this. Think of it like Legos. Legos are just a bunch of pieces. You can assemble them into various cool types of buildings, but Legos aren't building (just building blocks).

    Tasker allows you to automate various tasks based on different triggering events. In this case, the automation is turning data off... and turning it back on. The trigger is your screen turning off or turning on. The extra 15 minutes is just in case you're checking your phone frequently for a short stretch of time. During that short stretch, you don't want data to turn off every single time you turn off your screen.
