Previously I was one of the dissatisfied individuals with the Vibrant's battery life. I must say, since installing Juice Defender (and upgrading to Ultimate) my battery life has nearly doubled. Sure it limits when your data is enabled but I found myself experiencing nearly double the life with no perceived downside. Just wanted to help some of the folks cursing their battery life.
I have mentioned it to several people and I run it along with my wife of her 3G Slide and we have both been very happy with it. My daughter has a 3G Slide as well and is always complaining about battery life and the only thing she does is text which uses GSM and not the data service so I can crank her's way down and she would probably get a lot more battery life.
Can you explain how to use juice defender because I installed it but didn't like it. It turned on my wifi all the time. I don't want that.

Hey guys im in the process of doing a little experiment to see actually how much Juice Defender with Ultimate Juice actually improves the battery life on my Evo4G. I'm sure this has been done somewhere else i just couldn't find it so i decided to do the experiment myself and post my findings this may be useful to some people or may not!
Phone: Evo 4G
ROM: Cyanogen Mod 6.1.2
Kernal: Zendroid BFS @ 1.52ghz w/ smartass scaling
Launcher: Go Launcher

Phone running Juice Defender With Ultimate Juice
Phone Unplugged At 11:42am
Phone Died At 8:59pm
Usage: For the most part it was moderate use, no gaming, 2 calls lasting for a total of aproximatly 45 minutes. 120 texts were sent and received 146 within the time frame. There was no browser usage just mostly texting like i said. 3 Pictures were taken. No Wifi. Bluetooth or 4G used either.

Phone running without Juice Defender With Ultimate Juice
Phone Unplugged At: 2:50pm
Phone Died At: Never
Usage: Well my phone has been unplugged since 2:50pm and its now 12:35am and my battery is sitting at 55%. Weird... very weird. I had about the same usage as yesterday i played 1 game for a total of probably 10minutes and installed 4 apps. A had wifi enabled for probably an hour total.
-----------------------------------------------------------------------------
Final Thought: I think Juice Defender doesnt help at all, infact it seems to hurt your battery more than anything. I think it may be because its constantly turning things off and back on consuming battery? Thats the only thing i can think of. Does anyone else have any thoughts on why this is? Using Juice Defender reduced my battery life dramatically it almost cut its life in half as a matter of fact. Please share your thoughts on why this is people!

thanks for the info. i try to tell people that juice defender doesn't help. but no one listens so i gave up and just tell them cool app and walk away lol.
very helpful post. I noticed too it doesnt seem to really help it just monitors mobile data and turns it off when screen is off and occasionally powers it on to download emails and ****. I dont like it because i like to kno when i get an email instantly versus it checking every 30 min.
I also found that juice defender seemed to have a negligible impact on my battery life while also decreasing speed of sync/convenience. You'll notice that it also makes android system skyrocket towards the top of the battery use list.
On a related note, I also found that setcpu profiles don't have an impact on battery life and may even hurt.
Ultimately, android is optimized to manage a lot of these things on its own and introducing an app that consumes battery both monitoring and brute forcing some of these activities doesn't make sense. The only active monitoring app I use now is Tasker for some specialized automation activities.
i cant believe this is an app that most people recommend to improve battery life tho. Especially with how much it hurts rather than helps. Very disappointing.
It has helped mine because I use the widget to manually shut it off and on. I don't let it control it. Since the epic doesn't have the shut off data in the power menu its good for me. Otherwise I agree with you all. I keep my data off until I need it to look something up. Personal preference. But hey it does shut my data off when I tell it to.

I had been using juice defender and setcpu for a while trying to get the best battery life, but I ditched them both about a month ago and I'm getting better life than ever before lol
I've got 58% left in the battery and the phone has been up for 32 hours. I thought I was helping by micromanaging the phone with JD but I think it was really just hurting it.

32 hours up and only down to 58%? Mind if I ask how you set thigns up that your phone is so energy efficient?
It was a great application, Donut times, it literally made my Magic 32a survive the day against the not-even-a-day battery life at those times. Nowadays it is simply useless due to android better app management.
Hmmm...I have been using this for a few months now and I've seen dramatic improvement in my battery life. I usually unplug my phone at 7 each morning and by noon on moderate usage days I'm at 60%. Using JuiceDefender, my phone is typically at 80%. By 5pm with its only at %60. Normally I would get home at 5 and it would be around 30%. Interesting.
Running Samsung Captivate
Stock Android Eclair 2.1
Rooted
Zeam Launcher
With more iterations of Android they are improving power managment, Ya back a little bit ago this helped some people alittle it closing out processes and way to handle things but with android development alot of this stuff is getting worked into the OS, basically now all your doing is running a app constantley that does something handled by the OS now in newer builds.
I wonder in some cases if the juice defender and the OS both trying to do power management if it can actually cause more power loss due to a conflict in the two trying to controll items. Of course OS should have higher pid but could cause some of your increased power drain using both
try the beta
im using it on my epic and my evo i think it helps both but i am also using the free beta i dont think the regular one works
i'm shocked there's even a thread for this. i put it on a stock epic and it made a WORLD of difference.. especially in locations where my signal was poor and evdo service kept dropping. my issues with it are of a different nature. seems to get corrupt alot and the wifi locations service sucks
Hmm, i'm confused on how this could actually hurt battery life, especially by the amount you displayed unless you have it doing all kinds of other management as well. I have mine setup to only manage the data APN, disabling on screen off, and seem to have gained decent battery life from it. The widget to toggle data on/jd on/off is very handy as well.
Pretty sure android doesn't do anything natively that turns off data when phone is at rest/screen off, does it? Someone please correct me if i'm wrong.
I will admit, the new versions of JD do seem to be pretty bloated and sluggish.. i've been on the fence of whether to remove or not... The main reason i keep it on my device is because i work in a basement and get about 65% TWS and severe battery drain from that. With JD managing 3G, it helps mitigate that somewhat, and having it be automatic is much more convenient than toggling it manually all the time.
I may have to join you on some testing, because if JD is not gaining me anything, i'll definately be removing it as it sometimes causes some initial sluggishness when turning the screen on. From daily usage experiences (and i watch it like a hawk), my battery life has definately not been made worse.. older versions seemed to net me more life, and i'm undecided on the new versions. Not enough time with it on/off to decide yet.
Most Def Work
JD helps... it will slow down notifications and stuff, if you need always on data then this won't help. However, during the day I'm usually already online and don't need non-stop notifications and if you use JuicePlotter you can clearly see that while sitting idle with JuiceDefender on you use significantly less battery than if you don't have JuiceDefender active and have it sitting idle.
for those that think jd works...
are you using the free, pro, or ultimate version? looking to buy if it really saves battery life.
which configs did you use? I had it a few months ago and my battery did actually improve. Trying some different settings makes a huge improvement.
I am using superpower now. (from XDA actually) And this is really working, it also takes some configuration, but eventually it will benefit your battery life.
Superpower turns data to 2g when your screen is off, disables wifi and bluetooth and sets your cpu to a 400mhz cap (at least with my phone) I noticed a 1% overnight drain and a 200% increase in battery life. (basically I do two days with heavy use vs. one day before)
Hope this helps some people!
The only thing that actually changes the battery in an evo is a kernel. No quick fix app is going to help how your system interacts with your battery! Senseui is garbage and it sucks up battery life like no bodies business!
Right now I'm using RoyalGinger 3.0 on my HTC Panache.
I know that it's based on CM7, but if I switch to the actual CM7 Nightly or Faux's ROM which I'm also considering, will I get noticeable improvements in battery if I maintain the exact same usage patterns?
Hmm. That's difficult to answer. RG has really good battery life. Faux's ROMs focus more on raw speed than battery life, but still give decent battery life. CM7 doesn't have as good of battery life as RG, but usually lasts all day with all but heavy usage. At least, that's what I've found. Your mileage may vary. Your choice of kernel is important, so keep that in mind.
Sent from my HTC Glacier using XDA App
With moderate usage, I average roughly 11-13 hours using Royal Ginger and the kernel it comes with. Couldn't really find any benchmarks so not sure whether this is typical or not
This is with brightness set at the absolute lowest (Display On roughly 3 hours), Wifi never on, GPS never on.
OC'd at 1.1/245 smartass. Trying out On Demand to see if there is any difference
Well I know its not RG or CM7 but I run Virtuous Unity 2.35 and I am averaging 16-20 hours of battery with a average of 2.5-4.5 hours of display. It all depends on what you do with the phone.
There are many ways to help improve battery life. For instance Battery Calibration on the market. Follow those instructions and you wont go wrong. Another being Juice Defender (paid or free). A friend of mine is using an AOSP rom for his Evo and is averaging 30+ hours with Juice Defender.
Had no idea about that Battery Calibration app. When I flashed RG (and now MIUI), all I did was let the battery run down to 2% through regular usage and do a full charge until 100%
Flashed MIUI the other day, which I've heard nothing but good things about, including battery life, and am following the instructions of Battery Calibration now.
Not the biggest fan of Juice Defender. Had used the free version for a few days, and I found that sometimes it wouldn't re-initiate my data after the screen turned back on (which seems to be one of the more prominent features to save battery)

I agree with the Juiced Defender, that's the reason I don't use it.
For instance, when we are car pooling to school he has problems keeping pandora playing because Juiced kept turning data off. So he disables it when we are driving.
You don't have to use Juice Defender, of course, but the reason it re-initiates data when you turn the screen back on is that it turns the data off when the screen turns off. Turning the data off is what saves battery.
Hey all just making this thread see if any of you lovely people have any great tips on battery life. I'm running on the stock rom right now and I feel like my battery should be much better than what I'm getting. I have juice defender pro and I still feel like my battery should be much better than it is. Any tips? PS. I am constantly on my phone but I don't play any games just simply browsing the net with the occasional lost in YouTube moments. Lol. Thanks in advance.

I've heard (on other phones) that juice defender is bad on battery. Battery life issues could be from so many things...
Yea I just feel like I used to get better battery life on stock rom. Just uninstalled juice defender will have to see it makes a difference tomorrow.

I'm lovely enough to tell you it might be wakelocks, did you check for any wakelocks ?
There is nothing better than Greenify... just greenify the apps ONCE and never look back...
I think LG G2 have impressive battery life w/o any scripts and mods. You can install Snapdragon BatteryGuru, it can save some juice.
I have found a few apps to manage auto-startup apps which really seems to help my battery life. Of coarse the screen is always the #1 battery eater so always turn it off after using your phone (don't wait for auto screen off) I catch my wife doing this... she uses her phone, puts it inside the protector and straight into her purse, the screen stays on for another 60 seconds after every use.
Since i updated my phone to 5.1.1 my note 4 battery drains fast
What is a good battery app on play store that can help improve my battery drain
Juice Defender Pro is great combined with the app called Greenify... this combo has been used by some of the top developers for years
