Juice Defender

[Unibrow]

Your last quote:

last time I checked Juice Defender didn't in any shape or form attempt to kill or manage tasks on any level whatsoever.

And now you say:

"it manages your data connection"

Which is it?

I would consider your "lead-lined room" (I don't care if it's a kryptonite lined room) as a battery killer if you don't have something that manages how often your phone connects to data.

Juice defender doesn't manage tasks, such as apps which is what a task killer does. It manages YOUR DATA CONNECTION, which you could argue is a "task" but task killers for all intents and purposes are defined as unnecessary memory management which is NOT what juice defender does. I

I'm not going to have an argument on why you are wrong beyond this, you just are. If you want to define Juice Defender as a Task Killer, well that's fine. But you'd be as uninformed as the people that are using Task Killers to manage their Android devices memory.

I couldn't care less if ya'll use it or not, but unwad the panties. My opinion is it is a task killer, and yours is that its not. Whoopee.

It manages settings, not tasks. I completely agree with you task killers are bad, and would not use one because they cause more trouble than they are worth.

Labeling it as a task killer will frighten people away from it, I just wanted everyone to know that it is not in the same boat as task killers at all. You will find hundreds of places online, and Google themselves, saying that task killers are not needed. Therefore when you say "Juice Defender = Fancy Word for Task Killer" people will think they shouldn't use Juice Defender.

While you say it is just semantics, no it is not, two totally different things.

Ok, I see your labeling of it being a setting manager...I also just read several articles (just google a syntax with the words "juice defender task killer" and some others if you like) and go to the Sprint topics or Verizon ones and their engineers say it takes more power to turn ON the radios than it does just to leave them idle, not using any power. Especially if you're doing it every 15 minutes. It's the behind the scenes stuff that is saving the battery, and it involves killing (errr...managing) certain tasks. If you exit your browser using the HOME button, whatever page was loaded simply sits there in memory. When you kill the radios, Juice Defender also clears the memory, so now you have to refire the radios, and re-download the page that would have been sitting there had you not. (including email, facebook, and whatever else also) I agree completely that Facebook needs its own battery to function properly on a phone, but that is what's eating your battery...not the radios. Set Facebook not to sync up and you'll get the same effect as using Juice Defender. I've been looking at thousands of different threads about it at work today....because the boss is gone!!! Cheers!! Actually, I'm ahead at work, but it feels good to type that

Edit: Of course, for every thread that coherently explains that it's the syncing that eats the battery, there are 10 more that say "Juice defender works because my battery lasts longer using it", or something to that effect...It's the syncing though....not the radios.

Glad the boss is away and you are caught up -- two of my most happy times during the day!!!

I would really love the links because I can't find the articles that you are referencing.

I think I did find one, but I think you misquoted it. This sprint users forum post: Task Killer or Not... - SprintUsers.com if you look at post #7 it says almost exactly word for word what you said, with one important difference.

You said "If you exit your browser using the HOME button, whatever page was loaded simply sits there in memory. When you kill the radios, Juice Defender also clears the memory, so now you have to refire the radios, and re-download the page that would have been sitting there had you not."

But that post says: "Once a page is loaded and you leave the app with the home button, it is not using any battery. It is just loaded in memory ready to be used. Actually, killing it and reloading it into memory the next time you need it consumes more power. "

He is not talking about turning the radio off, he is talking about exiting the browser forces it to reload the page.

Saying that turning the mobile network on and off does seem to have some logic to it, but I just can't find any justification (not that it doesn't exist). But what you suggested seems crazy to me. If I have a browser open, turn the mobile network off, turn mobile network back on, why would that web page have to reload unless I went to my browser and hit refresh? I will test this out this evening and report back.

The part about the home button and clearing memory was 2-3 different articles I pieced together from different pages. I'll find it, but it's going to take me a bit. The memory clearing part is ONLY with the "advanced features" of "JD Ultimate" in the most advanced setting. That version has several "enhancements", and works like a gigantic task killer for lack of a better term. One of the items is a "memory enhancement tool" or something like that which effectively clears the memory when the radios get turned off. I'll find it, but I'm in a sensory overload at the moment trying to sort through conflicting articles/user experiences. I'm coming across a lot more articles of people having problems with it right now and am trying to find a commonality, but it appears to be like any other app (e.g. Runs great on mine and causes yours to lock up, or vice-versa with no rhyme or reason for it) I personally think that's the biggest problem with the Android OS; sloppily written apps. I say that as we could have identical phones with just a couple of different apps, and we both download a new app that comes out and our phones may completely different.

Give me a few...Hopefully I can track it back down, but I was using a work puter so I'll have to start from scratch here and I used a bunch of different syntax.

I used it for a while, but I got tired of it cutting out my DI stream. Honestly, the best thing I did for my battery life is root and flash CM7. It seems like my battery life has doubled since I did this. 8 hours in the hospital with light to moderate use in bad signal areas and I only use 25%-30%.

 

[stlrfan78]

I have ultimate juice, and juicedefender plus on my wifes phone. HUGE difference. i get 16-20 hours out of my evo with moderate use all day. i love how it auto connects wi-fi first for you, and it learns your spots as time goes. very cool app. the dev. is great,and is always working to improve, answeres emails and facebook feedback. i use it and have gotten tons of others to use it as well.

juicedefender and watchdog to monitor for bad apps, and all is good !

the best battery life saver is when you turn off mobile(3G) and 4G widgets.
Simply turn it off when your not surfing the net or using data. and then turn it back on when you do.
It only takes a mere seconds to do if you setup those widgets on a certain home screen.

When these two widgets are set to off? my battery will stay at about 95-90% for the whole day,
If I don't use my Evo at work. 4G radio is by far the biggest battery killer of them all strong signal or not.
