    Hey guys... just put on JD the other night.. first night i used it I huge! only lost about 7% over night compared to a usual 15% or so. so all is good. then yesterday I went into JD and hit a few buttons. I think the wifi button and something else. nothing seemed to happen but the wifi logo highlighted a bit.

    it still says enabled at the top. and my widget still shows 1.85 x's.

    but when i woke up this morning i lost the old amount of batt life.... like 15% ish.

    how do i know if i have juice defender set up to work optimally?

    thanks

    i have...

    timeout - do nothing
    sched - enable data for 1 m every 15m
    night - do nothing
    batt - keep data disabled while below 15%
    traffic - leave data enabled while >50kb/15s
    peak - do nothing
    apps - do nothing
    screen- leave data enabled while screen unlocked
    location - do nothing

    is this optimal?

    I don't know if that id optimal or not, but those are my settings and the defaults. It helps me to get through an entire work day without having to recharge.

    Here is the way I have mine set up:

    I set mine up via the custom mode:

    Enable data disconnect when the screen is locked to the following
    Schedule: Every 15 min during the day for 1 minute, Night: 12:30AM to 6AM - airplane mode so that connectivity is disabled completely.

    Apps: I have connectivity disabled on all of my games so that while playing games that don't need the internet, I get two advantages of placing the games in DISABLE.
    The main advantage is I won't see advertisements that get fed to the game via the internet. The second advantage is saving battery life.
    Certain apps: are placed in visible mode makes sure that they don't get disabled when the screen is disabled. For example: programs that automatically update at certain times should be either left in visible mode or service mode so that they can run in the background if needed. Experiment: usually visible will be good enough.

    WifFi: I have turned on. It will automatically turn off the WiFi if you are not near a network that you have previously logged onto. It will turn WiFi on automatically if you are within reception location of WiFi. This take a while to get trained so that it works properly, requiring you to sometimes manually turn on WIFI for a while until it learns where your networks are located.


    For me this is working very well. My battery usage is usually double except on days with heavy usage. Even then, I am getting improvement by at least 1/3rd.

    It's seems there was an update to JD the other day. This is one of my favorite apps. It has easily increased my battery life 2 fold since I got the settings tweeked to where they should be.

    Yes, the new version JD is a great improvement. The interface is much simpler to use with better explanations and warnings.

    According to the support website, there will be a manual coming out in the not too distant future which should help people get the most out of this application.

    To get the most out of Juice Defender, you really need to purchase Ultimate Juice. It is an add on application which significantly improves the functionality of the free version. It is a no brainer now to get it for only $1.69, a significant temporary price reduction from the $4.99 previously charged. Whatever, you pay for this application, it is worth it. If you have the old Ultimate Juice or the old Ultimate Juice alternative version, there are updates that will work with the new Juice Defender.

    BTW, if you have the old Juice Defender, you need to uninstall it before downloading and opening the new version.

    The only people who may not realize much battery savings with this program, will be people who's phones seldom experience any down time.
    If you constantly use your phone to the phone for either data or calls, JD won't help you. But if you sleep at night, even then, JD will help.
  7. Killing tasks twice a day (with free 'Advanced Task Killer'; in the market), even though some of them will come back up after a few minutes, and switching off WiFi and GPS polling when you don't need 'm anyway, will at least double your battery life.

    No Juice Defender necessary.

    I respectively disagree with some of what you are saying..

    Tasks killers with Froyo have been shown to be almost useless. (There are many discussions on this forum with a majority of people agreeing on this.) But in simple terms, this is their argument: As you mentioned many applications, so killed with an ap killer, will comback up after a few minutes on their own, using more juice to restart than they use when they are just sitting idle in the background. Furthermore, killing a background application that isn't using juice, will make your Droid opperate more sluggishly because it will take more time to call up and activate that application when you do need it. Moreover, Froyo kills applications that aren't being used for a stretch of time, anyway; so you don't need to kill them. On occasion, if you have a bad application that eats juice, a task killer might be helpful to end that application more quickly than Froyo will, but it is far more effective to remove a bad application from your phone, rather than to keep killing it.

    I agree that you can turn WIFI on and off yourself and save juice, BUT Juice Defender will do this for you if you forget.. IMO, is a great application because it AUTOMATICALLY turns off WIFI when it isn't available or when you screen is turned off. When WIFI is available and nearby, it automatically turns it on. Then 3G, which uses more juice and is slower that WIFI than readily available WIFI, is turned off. If WIFI can't be found, juice defender stops searching for it after 2 minutes, and activates 3G. It then autimatically turns off the WIFI for you, but will periodically, every 5 minutes, search for known WIFI networks. If it finds one, it turns it on, and 3G off. If you prefer, you can manually turn off WIFI yourself and juice defender won't look again for a WIFI network until you reactivate WIFI.

    Sure, you could remember to do all the switching of WIFI yourself, saving yourself buying Juice Defender. But Juice Defender does so much more than switch on and off WIFO.
    It lets you manage your applications, so that you can individually choose if data connections run or don't run while using a certain application. For example, say you are playing a game or reading a book on your Droid. If you disable data connections for this game in Juice Defender, each time you load the game, the game will not access the internet and you won't be bombarded by all the advertisements that come during your game play. At the same time, you are saving juice.

    At night, Juice Defender will also automatically put your phone into silent mode or airplane mode, according to your set schedule, saving a tremendous amount of juice during the night. Two schedules can be set for week days and weekends if you want. Sure, you could do this yourself, if you remember every night to put your phone into silent or airplane mode, but chances are, you will forget.

    Unfortunately, Juice defender won't automatically turn on or off GPS for you, although that is a feature that may be incorporated into future versions. (It would be nice, for example, if an application needed GPS if juice defender would turn it on automatically; then turn it off when exiting that application). You must manually now turn GPS off, and you should to save juice when you don't need GPS.


    IMO, EVERYBODY, can benefit from juice defender, except for people who don't sleep and who use their phone's constantly without rest. Many people complain their phones eat up batteries even during standby. If your one of those people, that's where Juice defender really shines. Not only will its night mode work better than the one you could set within your Froyo settings, if the correct settings are used, you can save a lot more energy during the day as well, even when your screen is active.

    Juice Defender works but you need to take the time to set it up correctly. While the new version is better at explaining how to do this than the old version, what is missing is a manual explaining everything in detail. The developer is working on this.

    BTW, if your phone is rooted, Juice Defender has additional features to save juice. I can't vouch for how effected those additions are since my phone isn't rooted, but I can vouch that for my unrooted phone, I am experiencing a significant improvement in battery life.
  9. Sure, Doc. Theoretically you're probably right.
    But IRL my 'm.o.' works.
    The proof of the pudding is in the eating.
  10. "respectively"?

    Sorry, respectfully, not respectively.

    What ever works for you, 3BIER, by all means continue to do it. I am just curious, if you actually have tried Juice Defender or not, when you say people don't need it. If you have tried it, particularly with Ultimate Juice, then your opinion is especially meaningful.

    If you haven't tried the latest version (released in the past week), you might want to look at JD again. The new, easier to use interface and built in instructions make it clearer how it should be set up, because if you don't set it up correctly, JD just won't do much for you.
    It has more functionality than the older version with many setting options not available with the older beta version.

    I've just reinstalled it now, I've always found it causes my phone to become sluggish in the past, usually after a day or so. Fingers crossed this time that they've fixed that in this one (I did report the bug to them last time).

    It does really work for the doubters, I usually manage to make my battery last 2 days instead of 1 with it but in the past I just couldn't put up with the sluggishness. I'd probably consider myself a moderate user.

    I tried "Netschedule" and "Y5" that do some of what JD does. My battery drain was much more with them (especially at night), than doing things manually. My hours are to random to set a schedule. I manually turn on airplane mode when I get home (5:30-7:30 PM), and off when I leave for work (8:00-10:00 AM). This saves me the most battery. I manually turn on WiFi to my home network only when I need it, maybe an hour 2 or 3 times a week. I get no bars at home, so I am in airplane mode 10-12 hrs per night, and most weekends. I lose 0-1% battery at night, 20-30% during the day.

    I like the idea that JD will turn off all data by application. Does it turn off all data and WiFi when the screen is off? That should help some. I'm just not convinced that JD will make any difference for me (especially at $4.83).
