Juice Defender and Advanced task killer for AT&T SGS2, do they work?
I found that Juice Defender helped, but it also annoyed me as it is able to save battery life by disabling WiFi/data connections while the screen is off--and then took a few seconds to actually reconnect when you turned it on. Some may not mind this, but it bothered me.
As for task killer, I've only read that they do more harm than good, so never tried it.
Don't waste your time with those crap applications.....they are made to manipulate background running apps while they themselves ARE apps that run in the background.....killing processes that only restart themselves if need be....and are then killed again. Smartphones are not dumb. They do not need someone to tell them what they need to function well. If you need to save battery....shut off background data while you're out. Turn down screen brightness.....these are 2 little things that your phone leaves you in control of. Installing apps that control wifi sleep policy? Your phones OS has that built in set in the the wifi settings. Don't be duped by some "placebo" app. You have a awesome phone it don't need some 2 dollar app telling it what to do.

Advanced task killer wastes battery, the LINUX kernel is pretty good at managing the ram as it is. Thus atk is constantly running wasting battery, usually killing apps that don't need to be killed, in many cases apps that are expected by the os to be ready to respond to you when use your phone.
I don't know how many times I have seen someone complain that "my phone is laggy, my battery life sucks and ever time I look at atk it its killing more apps and clearing ram all over again."
I always want to say no duh!
The only thing a task killer is good for is killing a rogue app. Using one to run constantly in the background as a secondary ram manager is completely counter productive.

Like the others said above, atk is bad for your phone. It kills off processes that might just restart themselves, thus using up power (to remove them, then to restart them). Your phone's memory uses up the same amount of power whether it is empty or full. You might as well leave the memory full so that your phone can possibly respond faster to your requests. Android will manage your memory efficiently for you.
As for juice defender, I love it. I get about 50% more power without having to micro-manage my phone. I leave wifi and Bluetooth on, and JD turns them on and off as needed. It can overclock and underclock as needed, etc. However, if you're going to get an app, look into Tasker. That app will change your configurations depending on you're location. arrived to work? Sounds off, wifi off. At the gym? Wifi off, volume to max, Bluetooth on. It's very configurable.
I have used both. I only use ATKiller for apps I pretty much never use. As for Juice Defender (I have Ultimate) It works great for saving battery as it says, but like stated above, it does shut off all wifi and data connections and other things so it takes a moment for them to all start up when you need co0nnection. But if you're like I am where alot of the time the phone sits dormant during work hours its no big deal to have things shut off. Better to save battery for when you are going to use the phone IMO. So I like it.

i just didnt like that I was getting notifications late because the data was off. Maybe its only for 5 minutes but its still late and I didnt like that. I'd rather use a charger and keep my battery at a good level.
For me, the trade off of late notifications for marginally better battery wasn't enough. it didnt save on my battery life as much as I would hope for. I didnt think JD was worth it.
but thats just my opinion
I've never used Juice Defender - I think a few people had it cause drain problems on the Infuse.
ATK is useful for nuking apps that are holding wakelocks for way too long. People keep on ranting, "ATK is useless, Gingerbread has good RAM management" while completely ignoring the issue of wakelocks.
ATK is not a background process - when you use it, it kills itself by default after killing everything else.
Note: I don't use the autokiller features. I manually kill apps that seem to be eating data/wakelocking the device. I also nuke anything that I'm not planning on using any time soon to avoid any wakeups from those apps.
Back in early 2011, ATK was a required app for any Facebook user, due to Facebook holding extremely long-term partial wakelocks.
Bad news is that the current #1 battery drainer app is a "zombie app" that keeps coming back after killing it (Skype).

As covered in another thread, Skype is one of the most common root causes of the "Android OS" "bug".
(In general, the AOS "bug" is not a bug in the phone - but the nature of suspend/resume on this phone is such that battery usage due to an app using data too often gets blamed on the OS.)

I'm looking for a free alternative to JuiceDefender/UltimateJuice that can save me some battery life I would very much like being able to say turn off all 3G and wifi at night and then turn on in the morning, connect and update my Gmail + Twitter + Facebook etc and maybe again once every half an hour...
anything like that? I know it's allot to ask for especially for free but money's tight at the moment
apndroid has a widget that will turn off wifi and 3g
You can try sweet dreams app.
Also timeriffic
try data on demand
Or APNdroid
Tasker can do this and MUCH more.. http://www.dinglisch.net/cgi-bin/yabb2/YaBB.pl?catselect=29
It'll be on the market soon.
That said; why do people insist on this sort? The only reason I disable "Background Sync" is so I don't get emails in the middle of the night. If it's a battery life issue, that's silly.. Just charge the phone overnight.
I've tried a lot of them but I stopped at Timeriffic. I highly recommend this one, it's free, no nagware and works as it is intended. I have a Desire.

Because in some country data package is not unlimit, and it charge on time-base not data-base (meaning if you open data connection for 10 minute, it charge you for ten minute even if you not download anything)

Thanks for using and suggesting Timeriffic to others. We appreciate the endorsement. As noted you do get control over the time to toggle on/off. The biggest battery drain is screen brightness for those of you looking to stretch the battery. Manage it and you will gain a lot of extra minutes of daily use between charges.
I also recommend Timeriffic. I have been using that app since almost the day I bought my phone. I have changed very few settings and it has helped out quite a bit. I also installed JuiceDefender but since I was already using something else, that seemed to be doing just fine, I really haven't done anything with it. I am sure you cannot go wrong with either app to be honest.
Just picked this up for my girlfriend. I currently have an Incredible, rooted with CM. She will not (or at least I havent convinced her to) let me root at this point.
What are some ways/apps to help manage the battery?? Connecting to Wifi at work will help the 3G/4G search drain but I need to take it further.
I'm looking for all suggestions, from sync setup to brightness setup to animations to apps.
Set the screen to automatically turn off after 15-30 seconds, use the LTE on/off app to disable 4G by forcing 3G only unless you need the extra speed (assuming you even have 4G where you are), don't use dynamic themes, limit how often apps sync data, set the screen brightness to automatic, and use a task killer to manually kill (don't use auto-kill unless there is an auto-kill whitelist as most apps don't need it) stubborn apps that want to constantly run in the background.
If and when she is willing to let you root it, then use SetCPU to underclock when the screen is off and freeze (or rename) the built in apps that she doesn't use as many of them will not only run on boot but will keep reloading themselves if killed.
Using all of that, I can get over 30 hours on standby assuming fairly light usage (a few hours of talking via bluetooth). Of course, with heavy usage (such as with streaming video like the tv.com or epix apps) the battery life is much lower.

Use juice defender from the market to turn off 4G while the screen is off. This added about 4 hours of battery life to my phone, standard battery.
Juice defender and green power are both great apps. As far as killing tasks, I've read that killing tasks can actually decrease your battery life because of how android handles the tasks and ram.
Androids tries to keep as many apps in ram to make loading faster, and if you kill all apps, the system will start loading them again, using more of your cpu, therefore decreasing barry life and slowing the phone down. Android had a very good and smart task manager built in to the os.
That is my understanding. If I am wrong, please correct me.

If you can't root, the next best option is a spare or extended battery. Apps like Juice Defender help a little, but no software can replace a real battery. I used JD until I bought some batteries on ebay.

It can, but there are also quite a few apps that will keep consuming lots of CPU cycles in the background. Some games are like this as well as some of the video streaming apps.

This is true. Autostarts (in the market) prevents such apps from running in the background & draining battery.

Turn off wifi when its not available.. scanning for it can drain your battery quite a lot. Obviously turn 4g seach off if you are not near a 4g area. I have my screen turned down to about 30-40% and it stays there(its quite bright at that % anyways). Dont use any task killing programs.. android OS has a very nifty task killer program on it already where it prioritizes what tasks stay running or don't. I have heard good things about juice defender you might want to check it out. Turn off sync for all apps and put the manual sync widget on your screen and that will also save some battery. Those should help some but a big one which killed my battery before I rooted was the bloatware apps that HTC puts on the phone. Blockbuster runs something in the background that will kill your battery. It is called PMVtpServiceStart force stop it in running processes and open up blockbuster then install the latest update and then force close it again and blockbuster. That should stop it from running. However you have to do this every time you reboot. Those are all my suggestions.. maybe buy a car charger if you drive a lot. I have one and its nifty to just plug it in whenever I drive to get a little bit more power! Good luck on your phone. PM me if you have any more questions.
i loved juice defender and used to recommend it to everyone, but a week or so ago, i had an issue to where my 3G stopped working altogether. I could still turn my 4G on, and force 3G to come on to check for software updates, but then it would go back off. After 24 hrs of no 3G, i uninstalled Juice defender, and after a couple of reboots, 3G came back on.
I guess there is no way to prove for sure if it was juice defender, but i feel that it was. If you are willing to take the risk, i was able to get 1.6 to 1.8 times more battery life out of juice defender.

i'm not sure, i typically had my 4g turned off unless i had a big download or was streaming/using mobile hotspot. It would automatically shut the 3G off when the screen was locked, but then one day the 3G just wouldn't come back on. I went into the wireless network settings and flipped the LTE back on, and that worked fine. With my work, I am in/out of 3G-4G coverage, so having just 4G is unacceptable. After uninstalling juice defender and restarting several times, it came back on. Could have been a coincidence, could have been the MR2 radio, could have been a combo, i don't know.
Does the TB continue to search for 4G when the screen is off? Or does the 4G only drain your battery when you're actually connected to it?
I have searched the market and google, but I can't find anything that will work with my specific scenarios. I want a rules based app, if it exists, to activate gps when certain programs are launched, like Navi, or maps, etc. Then, the biggest reason I want it, is because I would like it to deactivate on close. I have a real bad problem of remembering to kill it when I am finished using it, so I end up killing the battery prematurely because of my own stupidity. I've tried my phone my rules, and two or three others, but I couldn't figure out how to set it up to do what I wanted. Maybe I'm just an idiot. who knows. Thanks for any advice.

Cyanogen has profiles like that, but I don't think it extends to GPS.
I've pretty much always run sense ROMs and I ALWAYS leave my GPS checked on. It only uses it when I'm using an app that needs it. I'm not sure where the idea came from that if GPS is left on it will use it all the time, but I've never seen evidence that is how it behaves. Unless AOSP is weird and does try to lock all the time or something....
I use Easy Profiles and like it a lot. It takes a little work to understand but is very useful and really helps me save my battery.
As the previous poster says, most apps turn off GPS when they are deactivated.

Stock rom and I leave my GPS on 100% of the time.
I get from 12 hours to well over 24 hours of battery depending on how I use the phone. The GPS power turns off if no software is hitting it for a location.
Turning off the GPS (or WiFi for that matter) has never changed my battery life.
Maybe I'm mistaken then. It just seemed like my battery died off quicker after using Navi. But I didn't actually do anything to verify this. I will also try easy profile as one poster suggested.

I'd suggest before adding another app that will CERTAINLY eat more battery, to take look at what apps ore services are eating power, and exactly how they're doing that. Even the basic battery stats displayed in stock Android will give you a rough idea. Something like JuicePlotter will highlight what and when certain basic functions eat power. If you're GPS is running, it will stick out as a different color blur coming off the power plot line.
I'm a strong proponent of power management through strategy, not brute force of apps managing it. Kinda like a bank with a good security system... it makes more sense to design the building well, rather than hire guards/apps to do the job at a higher cost in dollars/watthours.
I use Battery widget to monitor my juice usage, but it just "seemed" like my battery usage was worse with GPS on. But I don't use my phone in the same way any two days in a row, so it was probably just in my imagination.

If GPS is constantly on being used to update traffic, geotag photos, or track you on GPS, you're going to usually notice sharp drops in battery life. I use the battery widget too, but JuicePlotter can better illustrate where the power is going.
I'm a little surprised noone suggested Tasker, Locale, or SettingProfiles since they will all do exactly what the OP wanted and more. Tasker isn't as user-friendly as the others but seems to provide more functionality. I currently have it set just as the OP wanted. Turns gps on when Maps, Nav, etc open then turn it back off on close. Probably unnecessary but doesn't cause any problems for me so it's fine.
thanks A0. I will definitely check that out, as I think it will work for the other things I wanted to try too.

If you want an app which will schedule your connectivity like WiFi, 3G, Packet Data and GPS etc then you could use it, but if you think it saves juice and produce good battery backup then NO, it drains more than it saves, I know some users here who were fan of JD but ultimately stopped using it for battery saving. Now it's your turn to think on which boat you are.
Regards.
I'm using Juice Defender Ultimate and using Advanced profile. My last recharge lasted for 38 hours and still I had 15% battery left...and I'm on Lite'ning Rom 6.1...I'm not an expert...but seems like it's working.
For me its working great. I removed the blotwares from my phone (Hubs and all other useless things) and JD is working fine. I'm using the ultimate edition and very happy with it.
@ithehappy I guess we will just have to agree to disagree on everything bro
I too use Jd Ultimate, other than sometimes it stops working, it works great. I use it to overclock and control my cpu speed too. (with ninphetime kernel)

I don't like this kind of apps. I think Android does a good job with battery saving if everything matches well together.
Therefore search your
personal best modem.
personal best kernel.
personal best rom.
Add some smart tweaks.
And tada you will have a good battery life.
I have been using JD Ultimate for quite while with my old Desire & now my SGS2. On the SGS2 it displayed a number of problems:
- sometimes it lost its configuration data
- other times it would stop working completely
- the location feature where wifi was only enabled in the vicinity of known networks didn't work at all
- the feature where wifi was supposed to stay enabled when certain apps are a running didn't work
Just for fun I uninstalled JD a few days ago and my battery life seems quite a bit better than before. It took a few days to get into the habit of turning everything on and off manually. Mobile network and wifi are only turned on when needed.
Yes. I think it works. It's a good placebo anyways.
I use Tasker to automatically shut off the radio's when I'm sleeping. Works more reliably than JD's patchy on+off routine. Of course, you could just turn the phone right off as well.
I think JD does work, but I'm not sure if it's work the resulting inconsistant connectivity.
Removing bloatware (use CpuSPY and the Running services in the Applications settings to see what's sitting in the background) helps a LOT. Removing all of the useless Samsung UNA rubbish is a good start.
I've undervolted+underclocked mine to 800mhz, I can't notice any difference in usage, I'm not sure if it helps much or not, but I tend to get somewhere between 2%-3% per hour idle drain (the phone is in deep sleep so underclocking/volting is fairly irrelevant to this figure).
Whatever, the hardcore anti battery saving people might say it won't work. But I clearly see a huge improvement.
Running JD Ultimate saves me a lot of power. I easily get 2 days of usage (very personal, but it works for me - I use a lot of Spotify all day.. high volume )
It just works.. period. Turning off data and Wifi over time, included with other automated processes can't do much else than save battery.
Android doesn't need an app manager.
I voided my warranty and your mum.
I have it installed but only turn it on when needed. Ie if I'm out for a long day and my battery is getting low I'll turn it on. But otherwise I don't use it. I think it died help a little. But also there is the inbuilt power saving options in this phone that seem to work well too.
I use to use the app, and it did work for me, but I am no longer using it as I am now always close to a charger. when I need to conserve power (which is very rare) I turn off all data connections as I have found that this is my biggest source of battery drain.
The connection itself and apps updating in the background or when the phone is asleep, to add insult to injury, my data connection is very slow, causing the apps to keep the phone awake for a longer period to pull all the updates
hey, so i have ran pretty much every "jelly bean" rom out there for this phone for about 2-2.5 months. maybe less. note sure..
anyway, the battery has been horrible! on every rom.. I have a 2700 mAMP battery, and a regular Samsung battery. I have to use both once a day for this phone.. now I have no idea what is making the phone loose percentage after percentage of battery as fast as it has for me, but everytime i post i get about 0 luck from people that either have the same issue, or just people saying they have heard it a million times. i probably should have put this in the "Q&A" thread, but maybe i forgot. can someone, preferably more than one, help me out here?? i don't get how other people say they have 8 or more hours of screen on time with half the battery left. it just doesn't make since. I am loving the android system. but this could be anything! the apps in the background. the kernel, maybe I didn't clean my cache or something. i can't raise my brightness up to far or it'll drain my battery, jamie in the paranoid thread said he had his batter on 100 percent and had excellent battery. so I'm far from confused here. do I need to get another phone, or what. very much apprentice the help from as many people as possible. I love my phone, but I hate that i have to focus on using two battery a day with this phone.
Same here battery draining pretty quick on all jb ROMs.

Battery usage is highly subjective..
It's nearly impossible to determine a baseline Usage expectancy, simply due to the untold number of variables that drain the battery.
We know the obvious power users ....the display, wifi, data ..
But it gets far more difficult to track the Usage after that.
We know that JB is not optimized for our device, but it's getting better, and until we see a true JB kernel with the rom matched to it, the battery is going to suffer.
Then of course we have the many services that users run, along with countless apps ...
Long story short ....maybe a more stable choice would work better? ?
Like ICS, At least until JB calms down a bit ...
I'm actually running Saurom as I type this ...and my battery life is excellent.
JB just isn't quite there yet ...IMHO ....g
to get better battery turn brightness to lowest usable setting, turn off sync for any non essential apps, turn off soft key lights, flash a kernel that lets you under volt and under clock, try different govonors and io schedulers, turn off gps, put in airplane mode when not using. these should help. keep in mind cell signal strength will also impact battery and 4g will kill it faster then 3g. i am on cm9 stable under clocked to 1.18 undervolt all by 25mv( not much change but i like to be safe) ondemand and sio and get amazing battery life.
What's your screen-on time? 4 hours is the close to the limit on ANY rom for our Notes. You have to make sure it's not some sort of confirmation bias going on here.

Then of course we have the many services that users run, along with countless apps ...
Long story short ....maybe a more stable choice would work better? ?
Like ICS, At least until JB calms down a bit ...
I'm actually running Saurom as I type this ...and my battery life is excellent.
JB just isn't quite there yet ...IMHO ....g

thank you so much man! i actually went to at&t and they mentioned that too. they said the kernel im using isn't fully optimized for the phone yet. other words. the phone wont support it. he said basic stock ics is the best thing to do now. he also said. these forums are for phones from Europe as well. not just for AT&T in the us. again, the ROMS these devs are making are not supported for the phone, and is kinda like a mimic of something its not. he said jelly bean was out, but i don't know where to get it. can someone tell me how to install ICS, because when I download it, and use KIES, it installs the system, but never fully completes the process.

Sure...
At the top of the general note section, you will find the "note super everything thread"....
Scroll down to find the ICS info you need...
There are many great ICS roms, and you will find that your phone is "MUCH" better running on the software that was intended for it..
Do the homework in the superthread, and read, read, read......then if you have more questions....just PM me, and we'll get ya up and running....g

thank you so much! I will get right to this
I never got more then 2 hours screen on time on any ROM, just figured that was normal.
Ugh.
That is low scout ....
I pull 3 hours average ...
Must be the internut ..on XDA ....LOL ......g

I'm in the same boat as manel, never gotten anywhere above 2h on screen time. Maybe additional 10m or so. Figured it was normal lol

Battery life is purely subjective. No two people will have the same experience.
Have you used an app like CPU spy to make sure the phone is going into deep sleep? Rogue apps keeping the phone in a wake lock can seriously affect battery life, but its hard to say if anybody's apps are doing that, because we all use different apps and there's no list of apps that keep a wake lock, so you need to use something like CPU spy to see if you are going to deep sleep when your screen is off.
Related to apps as well, don't use any task killers or constantly kill apps when you exit them. A lot of people think killing apps is necessary when it completely is not. Android, since donut or eclair, manages its RAM very well, so that when a properly written app (ie. It's not keeping a wake lock) is in RAM, it's just in a frozen state not using any CPU cycles. Constantly killing well written apps hurts battery life, because restarting the app fresh is much more processor intensive than pulling a frozen app out of RAM. Plus you don't have to deal with annoying loading/splash screens.
Also, like others have said, using the lowest brightness possible, and turning off sync for any unnecessary apps will help battery life. GPS doesn't matter so long as you don't keep something running that uses it. If an app isn't using GPS, then GPS isn't using battery. I always leave my GPS on and do not notice a difference compared to turning it off. If you're paranoid about GPS leave it off, but it's annoying to have to turn it on every time you want to use an app that requires it. You can also disable location access in most apps like Facebook, twitter, etc where you don't need GPS really, and that will make leaving it on even better. If you don't use GPS much anyways, leave it off.
Like somebody said, your cell signal can greatly affect your performance, so use WiFi whenever possible, and even put a data toggle in your pulldown so you can disable cell data when you don't really need it. WiFi in general uses less battery than cellular data, so I use it whenever possible.
I've also noticed that how you use your screen on time also has a great effect on battery life. When I have extended lengths of constant screen on time where the phone starts heating up and whatnot, I see much less battery life than if I just use my phone here and there intermittently. Long stretches of screen on time stress the processor and battery heating them up and making them less efficient, where as short stretches allow the processor time to stay at a cooler, more efficient temperature. If you game at all on your phone, you've definitely experienced this, as you know that your phone heats up due to the extended lengths of screen on time and heavy processor usage. Gaming is a no-no if you're striving for better battery life.
With following those guidelines, my Note sees about 3.5 screen on time with JB on Gubment Cheeze. I would get around that on ICS as well, and I don't remember what it was on GB. Fellow testers and teammates for Gubment Cheeze have seen up to 4 hours and a little more even on JB, so it's definitely possible to have decent battery life on JB.
It really comes down to your own personal usage.

I was not aware of this info....many thanks for the heads up...I always supposed that since the ram was consumed with applications, that those apps were pulling CPU usage from the device...
that is clearly not the case......g
Yep, no problem. If you go back to a touchwiz based ROM and go into the stock task manager, it shows you what's taking up RAM, as well as the CPU usage of each thing in the list. If the apps are working properly, pretty much everything will show very little to 0% CPU usage, and ones that are using it heavily will even be highlighted in yellow or red depending on their CPU usage %age. Unfortunately aosp based ROMs don't have that task manager, one of the things I miss from touchwiz.
Every time a non-techy friend buys a new android, it seems the overly aggressive sales rep that sold the phone to them 'helped' them get to know the phone and installed a task killer, specifically advanced task killer. I always just uninstall it without telling them and see how long it takes them to notice lol.
It's still useful in certain instances, for example if you have an app that doesn't run well but you still like/need to use, but in general practice android does a much better job of managing itself. Besides, if you have an app that you know runs poorly and hogs your processor in the background, but you still need to use it, with most aosp based ROMs you can set your phone so that long pressing the back button kills the current app, essentially making task killers useless.

That's a very big heads up. Thanks. But thing is when I have wifi on. Don't I need to be connected to wifi network first before it actually can help me??

This is true. What kind of signal strength do you get where you are at? Does your phone bounce back and forth to lte. I have noticed when i go from a strong signal to weaker signals or band switching a lot, my battery drains rapidly.
Use cpuspy, as mentioned, to verify you do see deep sleep. Also, i find if rooted, that seting the min speed to 192 helps quite a bit.
