Hi,
I've been playing with Juice Defender (free version on Balanced Profile) as well as Tasker. As far as I can see JD is more or less disabling the wifi and mobile data when it's not needed. I will say I've noticed an improvement in battery life with the free version of JD in balanced mode.
On the other side, I just recently turned off JD to try out Tasker. Right now I have Tasker turning off the mobile data and wifi when the screen is turned off then while the screen is still off Tasker turns on the wifi and mobile data every 30 min, and keeps it on for 5 min, then turns it back off again. and the last step is that Tasker will turn on wifi and mobile data when a user unlocks the screen.
So my question is - which one is better at saving battery? In my Better Battery Stats it seems that JD is not turning the wifi and mobile data off, rather just disconnecting wifi. Additionally with Tasker it seems in BBS I now have a "connectivityservice" that seems to have increased its battery usage (not always on/connected).
Thoughts?

OK you didn't mention how battery life improve with Tasker. See you could have easily got the results yourself as you already did half the work with juice defender. You just have to do the same with Tasker and compare the two.
Well the jury is still out on battery life with Tasker...I guess I was more wondering if anyone knew if that's all JD did (turn off wifi/mobile data). If that's the case then I'd assume Tasker would have similar effects on the battery...and since Tasker can do so much more, I'd probably buy that instead of the higher levels of JD.
So perhaps that's a better way to word my question.
Well the free version of DS battery saver does more as it closes all apps running in the background. Combine that with Greenify and you will see improvement in battery life.
also going to vouch for DS battery saver. ive seen many post good results with it.
I only turn data and wifi on when i use them though so im not too familiar with it.
I found I have better life with Llama, than I do with juice defender... And I used the paid version, tweaked to the hilt.
I have been using juice defender ultimate for almost a year and can say it was the best 4 or 5 bucks I could have spent. With the ultimate you have more options. I am usually up between 5 and 6 ever morning and unless I am making a ton of phone calls I can make it until 8 or 9 every night.

So ever since I first bought the G2x, I've always had juice defender a part of it. Now having done a factory reset, since May (when I got the phone) and not installing juice defender, it seems that I get the same if not better battery life without juice defender installed. Could juice defender just be adding to the battery drainage also?
Yea, I am in the same camp. Juice Defender really has done nothing way too much tweaking it. I have to say its like all of the purge from memory apps...you mileage might vary, but for me they aren't really helpful.
It seems to me that juice defender might be good for over-night, or for situations when I'm not going to be checking my phone for hours. Otherwise, the radio keeps getting turned on and off...on and off...everytime I wake the screen to text or something...that's in addition, of course, to the regularly scheduled times that it does it on its own.
But then again, instead of having it running all the time, I could probably get the same effect if I just went to airplane mode overnight.
Interesting point, OP...and gave me something to think about.
I'm gonna test that today, yesterday I got 15 hours with it on and set CPU profiles today ill turn off juice defender ultimate, ill keep u guys updated.

Yeah, I tested this week. Ifound no noticeable impact of juice except maybe overnight. During the day, and no impact, and perhaps even a negative impact.
I just manually toggle data off at night anyway.
There is really no reason to ever use juice defender when Tasker exists. It can do everything JD does and SO much more.
After testing pretty much every setting I could think of, the only things that made a significant difference is disabling data and GPS. I set up a screen off = data off, screen on = data on set and battery life WAS improved. However, I use Google Voice for all my texting, so I had to have some data, so I tried the same thing but reducing to just 2g and no improvement was noticed.
Keeping GPS off permanently but allowing it to run specifically on applications that need it helps too. Note that this is not possible on gingerbread except for CM7 and ROMs built off of CM's source. I imagine toggling bluetooth and/or WiFi would influence things too, but I never use either. No other setting resulted in a significant improvement in battery life.
Note that during all of these tests, I kept screen brightness to 18%, toggling to 25% when in direct sunlight and 0% in the dark. As for airplane mode at night; I plug the phone in at night and unplug when I wake up so this is a nonissue for me but AM is the best you will ever see your battery life without using things that require root.
And, of course, underclocking to minimum when screen is off improves more than everything else combined. Kernels and clock speeds matter far more than things like GPS or data connection.
Well I'm through testing today I got 11hrs and 18 min without juice defender compared to 15hr with it yesterday, and I used my phone less today, so juice defender gave me about 4 more hours, tomorrow I'm gonna use juice defender and 2g.

Oddly enough, the free version seemed to work better that the paid version. A lot of the time wifi and 4G will stay on even when not using the phone, and I have to manually turn off/on wifi depending on the situation. As stated, it does help when not using your phone for a while, but I'm no pro at it or anything, could be the settings.
Does it actually work? Or does it work like as task manager killer, known to drain battery even more??

Its works good. There's a feature that turns off the radio when tthe screen is off. Works great

some will swear by juice defender, but from my personal usage of it i just got less battery from it.
I do use automateit though to turn off my data when the screen is off, and to turn data on when the screen is on. what i like about automateit is that it used less resources (at least according to watchdog lite) than juice defender. Also, it has the options to set a timelimit for the rules (an example would be to turn data off after 5 minutes of the screen being off).
Using automateit my battery went from 13 of light use to 17 hours of medium use (i read alot through pulse newsreader) and 48 hours when its light use (checking the time here and there at work). When doing both i tend to average at around 23 hours.
Best thing to do though is just to test juice defender and automateit on your device because your usage differs from everyone elses. (though use watchdog lite! cpu cycle watching is you best friend for getting better battery imo!)
thanks for the responses~
JD works. I prefer Green Power, though.
i use juice defender ultimate and i love it. it turns on/off radios on a schedule if you want, and even uses wifi when you're in certain areas (via cell tower association). i get decent life without it on gingerbeast (15-20 hours usu) but with it, ive gotten over 30 with regular use.
like was mentioned above, try them all out. automateit sounds good and is probably a lot lighter than juice defender but JD has a LOT of capabilities so don't just pass over it because it's a big app...look through all the advanced features and give it a fair shot. it tells you how much it's affected your battery life by and i'm almost always at double battery life thanks to the app
I used Juice Defender on my Vibrant and it seemed to help quite a bit. However, on the Sensation, because it is running gingerbread, I have read mixed reviews. Some say it helps, some say it doesn't. I'd like to know your experience with this or other batter saving apps!

If nothing, it starts/stops mobile data when you turn the screen on/off. That on its own is a huge battery saver. It also turns wifi off when it's out of range, and mobile data off when you have wifi.
These things obviously increase battery life, no question about it. Of course, if you never have mobile data on, and don't want to have it on, there is no point to having juice defender
I find that it perpetually signs me out of Gtalk
Hmm. I was debating whether to get the elite version on the market as it seems to have a lot of extra features. I didn't know there were mixed reviews with gingerbread. Thanks.

I get an issue with juice defender where after I've turned the screen back on there is still not mobile internet connection.
I have to manually put the phone into flight mode and back to get a connection, and sometimes even need to reboot.
I got pretty much the same advantage as JD without the hassle by just enabling 'Power Efficiency' in the 'Power' menu in the settings. It turns off background data like JD and allowed me to go a full day with fairly high usage and still have 30% at 8pm.
N.B. - Having background data off means your widgets and mail won't sync as often so I put a 'Sync all' widget on one of my homescreens so that when I wanted an update then I could pull everything down at once.
Hope this helps
I've been using juice defender but I think I will try your suggestion for a couple days and see if it makes a difference. Thanks!
If you check the "always allow mobile internet" button in your wireless settings will give you a good compromise between stock and how juice defender constantly kills the data connection. That setting for me is good for an extra 20-25% a day. Only thing I notice differently is emails may take a minute or two to arrive and Gtalk is signed out when I don't have the phone active.
Juice defender will just manage your apps, settings to save battery.. just to regulate your battery..
I am using Juice defender and it's saying 1.61x now, the battery last about 3 days(I am not a heavy user) but before that it didn't so I found it to be quite helpful
yeh me too... from 8 hours to 10 hours with juice defender..
I really need a better battery life for my business phone. My last 3 androids have all had a 20% battery by 3pm....
All of the battery apps claim to turn off network when screen goes blank and so on... however I still have bars of service imidiately after turning screen on. Will I still receive phone calls?
Root your phone, under clock when screen off and manually turn off your interwebz...
Rooted MT3G XM-8 Even Moar Stripped with XDA Premium..
FB is one of the bad culprits. I generally use Autokiller on strict to tweak the Android process things and it works good.
Did you try Juice defender? It's the only one I've tried and works fine so far. My battery last 30% longer after using it, and it wasn't tweaked.
If you don't want the hassle of underclocking, then just go for apps like Green Power and Juice Defender. Set it to turn on every 15 minutes during the day and totally off during the night when you sleep; you'll be surprised how much time you can squeeze out of your battery.
You must use battery saver pro or juice defender and task killer
Okay, task killing apps randomly won't always improve your battery life, for an example, if you kill let's say a play on tv app which is a system app, you might end up wasting more battery as it re-starts.
Juice Defender
I can personally vouche for Juice Defender Ultimate. I love this app, it's always the first I install when I get a new phone. It's saved me at least 3 hours of battery per day. I have the extended battery upgrade on my HTC Rezound, and I used to be at around 30-40% after a day at school (somewhat heavy 4G use, like listening to Grooveshark, browsing the web frequently, etc). Now, with the same, if not more usage, I'm at close to 60% by the end of the day, and it lasts me usually until around 9 at night.
So, Juice Defender=awesomeness. And you're going to want the Ultimate version for extra settings, definitely worth it.
I personally found that Easy Battery Saver which is free on the market gives me the best battery life even better than JuiceDefender which I found hard to believe till I saw the results. My Motorola Atrix has really bad battery life usually only lasts me about 5 hours without the app but with the app it lasts up to 8 or so which is a pretty swell improvement if I say so myself.
I would also say that Juice Defender is a good app... saves quite alot of battery.
but all of the apps using data in the background (facebook etc.) are the battery life drainers
Use juice defender
I use Juice Defender myself. works fine. you can edit what you want on or off. Also memory killer works but you need root

I can second the votes for JuiceDefender - it's done wonders for me.
For the rest of your questions...
Even when an app is toggling your data connection for you it won't affect your cellular connection. You'll still see bars of service (though without a data indicator next to it like "3G" or "H").
You will also still receive phone calls and text messages as (again) your network service remains untouched. Emails or other data services will be delayed until the app enables data.
Try out Bataria. I really notice a difference using it.

That's weird, I got about 1 day of battery life with my Atrix, sometimes 2 when I disable data from time to time.
Which rom do you use ?
Anyway I also use JuiceDefender.

it depends what version of android it has with 2.2 or higher i read that they manage memory pretty well so the task killers might actually take more battery rather than save it. If your Phone 4G you will save alot of battery by turning it to 3g and only turning on 4g when you need the speed

Task killers are never necessary on Android. Apps to manage and toggle data and radios are far more useful - and can be quite beneficial to your battery life.
Which one do you guys prefer

Neither, bit tend to interfere with advanced configs and from my experience power users tend to advoid them. However, juice defender seems to be the lesser of the two evils. Personally I undervolt and underclock and get far better results
If you don't want to get into kernel changes (undervolting/underclocking), give JD a try. I've been using it for months and found, at least for me, a significant battery power savings using it. Spend the extra couple of bucks and get the JD Ultimate key.. it unlocks a bunch of features. With the same type of use I noticed about a 6 hr gain/day (was getting ~ 14hrs on a charge.. now anywhere from 20-24 hrs). There are many setting combinations, so you'll have to experiment what works best for you. I have it set to turn off the data connection when I'm on WiFi... and when my screen is off, have it set to turn off all radios (and while screen is off, you can set it to ping certain apps like gmail, facebook, etc just for a minute, then turn back off. It automatically will turn data on when you leave your Wifi area. You can also train it to turn on/off certain radios depending on your travels, time of day, use of certain apps, when battery gets to certain levels, etc. It has some cool widgets which show which radios are on/off and can be quickly toggled as well. Anyway, it takes a while to figure out what works best for your situation, but it is very flexible and has tons of features.
Contradictory to what I've been reading online about battery saving apps; I had GREAT results with easy battery saver. I know the app looks cheesy and the fact that i never heard about it before downloading from market.
Due to poor network signal at work, id barely have any charge left on my phone once i get out of work (8 hrs). this kind of apps really help.
JD seems to cause more conflicts/problems that it helped me, even if i turn off untested/expirmental. JD looks more sophisticated/advanced, it didn't work well with me.
The features which mainly effects battery life imo are:
1)Traffic scheduler
2)connectivty killer when screen is off.
These are must features for me, to get whatsapp msgs and email sync. and it seems that easy batter defender scheduler is more robust.
I usually choose to allow sync every 15 min with 30 sec window and connectivity killer to around 20kb/30s. I had bad results when letting the app manage my wifi connectivity based on location (remember wifi networks), better turn it off.
Other settings, screen timeout/brightness/UC/UV/cpu cores/deep_sleep/kernel/modem, must be explored to get max battery life.
Remember these apps will not help very much, if you are using your phone(i.e. screen is on). they work best when phone screen is turned off.
I'm currently using Battery XL from market to test it out.
Another app worth looking at is Green Power. It also can shut off data and turn it on in intervals for emails, IMs, etc.
They both are good options. I have used Juice Defender for several months and it is very good. I have installed Easy Battery Saver last week and it is also good. I only did the change from one app to another for trying
