JuiceDefender on Nexus - Samsung Galaxy Nexus

Has anyone tried this out? I just put it on and have not gone through a battery cycle. Trying to see if it will help with battery life.

Some people swear by it, but then again some people believe a supernatural being exists because someone said so.

Yeah I've used it since I got the Nexus and it works great. Does what it's supposed to do. I don't believe in supernatural beings though.
Full disclosure; I have had this bug which manifests about once every week where the touch screen becomes completely unresponsive in the lock screen and there is no way to unlock the screen or turn the phone off unless I pull the battery. I have this nagging feeling that it might have something to do with JuiceDefender but I haven't confirmed it.

I purchased JuiceDefender and also Green Power Premium and never really noticed a big difference in battery life against leaving them off and changing wireless profiles.
Getting almost 2 days out of my Nexus so may give them a go once they both fully support ICS just to test.

Disable JuiceDefender for a week and see if that bug still exists. If not, problem solved. You can do the same as juice defender by pushing the multitask button and swipping away any apps you don't want.

JuiceDefender is not only great for a little energy saving, but also for featured like WLAN by localization and display Brightness configuration.
I used it on the S2 and now on the GN.
On Ics it has some little bugs yet, but it also does seem great job here.

I have the basic version of JuiceDefender running on my GN and I swear its making a noticeable difference in battery life.
I have it set to disable my Data connection whenever the phone is locked. It re-enables it when I unlock it, so it doesn't come on when I'm just checking the time. The effect is immediate too so data is there when you need it.
It also comes on once every 30min just to let apps/email sync briefly.
According to JuiceDefender its improved my battery life by 1.7x. I'd be inclined to say its about right...

Lol it does a bit more than that mate. It's the radio function management I need since I'm always too lazy to toggle them manually. I've been meaning to disable it to test if the lock screen bug would go away but I find it hard to use my phone without it now that I've got so used to it. Now that's it's the Christmas holiday though I might give it a go.

It made a big difference in battery life but it takes way too long for the device to reconnect to the mobile network when i wake it up. Likewise, it will not allow me to get my emails throughout the day unless I wake it up.

The multitask button doesn't kill apps - swiping just removes them from the list. Its more like a recent used apps list - like long pressing the home button on Android 2.x use to be - than a multi task manager showing running apps.
As for juice defender, I bought ultimate, and it was just horrible. Very laggy UI, and felt like it was causing more battery usage itself than saving. The comments for 'ultimate' on the market seem to say the same thing. The free version seems much better, although you don't have as many options. There's also another paid version which is cheaper, but I havent tried it.
Put it this way, I uninstalled it Waste of £4.99 which is a ridiculously hefty price for something that cant even get its UI right.

I can confirm the same behavior on my phone with JD, forcing a battery pull a few times a day. after uninstalling it, I get no more unresponsive screen. I can only conclude that it wasn't playing nice with ics

I hope Juice Defenders Team will optimize JD for Android ICS, because I loved the program for its features.

i have this on my GNEX and it is awesome.
yeah some little quirks BUT, definitely prolonging my battery due to wifi/mobile data management.
i'm not experiencing the unresponsive issues and stuff you guys are reporting..
maybe its another app????
i'm getting more than 16hrs on my phone.
as for ultimate. no need for that unless you have a rooted phone.
pro is very good.
i picked up th pro version for $0.99 when it was on sale.

JuiceDefender Ultimate
Hi,
I'm using it on my rooted GN 4.0.1, works well.
By using 3G/WLAN management I come up to 25 - 30 hours lasting battery power.
At home and in my office I told JDU (JuiceDefenderUltimate) to switch to those WLAN's and disable 3G there.
I'vnt tested all the other features like cpuspeedcontroll, or something else.
For me it works perfect.
regards
J.M.

Steps to prove yourself incorrect:
1) Install OSMonitor
2) Open GMail
3) Go to homescreen and open OSMonitor
4) In the process list, make sure GMail is listed (it should be!).
5) Press the Multitask soft button and swipe away GMail.
6) Check for GMail in OSMonitor and it will have disappeared as it is no longer running.
Magic!
Sorry I'm just on a personal mission to stop this misinformation from being spread.
---------------
On-topic: I've used JuiceDefender Ultimate on all three Nexuses over the years and I certainly think that it makes a big difference by turning wifi off when not in use and turning mobile data off when the screen is off, although I have loads of other settings configured within the app also.

JD Works Great
I have been using JD Ultimate on my Nexus and it works great (I would estimate 1.5 - 2x battery life).
I used the Nexus for a little over a week without JD just to have a set expectations of what my battery life is without JD.
I have not seen any bugs with this up til now.

I get the same issue and I dont get it when I uninstalled Juice Defender
My phone also reboots randomly and I am wondering if its linked toJuice Defender. The reboots only started recently

I use JD free on my GN, although I haven't seen what battery would be like without JD on it. On my Incredible, JD made the difference between not getting though a single day to getting almost 2 days out of my battery. On my GN with JD I'm still only getting about one full day's worth out of it, sometimes not quite a full day.

I am using Juice Defender Plus and it is set to manage it self then WiFi and 3g network. I am using wifi at home and in the office,and the rest -3g
In my opinion....jd plus does worth the money spent.
14 hours and 20 minutes used - 46% of battery left

Ice Cream Sandwich seems to do a lot of the things that JuiceDefender did on my old phone. For example, data is automatically turned off when you are connected to WiFi. I had it installed for a while, but when I looked at the list of apps that were using the battery (in the Android settings menu) JuiceDefender was listed as using a fair amount of battery. I'm not sure it is worth the hassle on this phone.

[Q] juice defender

Aight so I downloaded juice defender free last night cause I've been having battery heat problems.....but it shuts off my 3g connection when the screen goes off and I can't seem to find the setting for it....I use Pandora radio so this is a bit of a *****.....any solutions?
Sent from my Incredible using XDA App
Thats pretty much the only thing Juice Defender free does that can save your battery, that and turning off wifi too. So if you disable it why even have Juice Defender installed? I too tried the free version for about 2 days and could never get my wifi or 3g to come back on so I uninstalled it and thanked god I hadn't paid $10 for the paid version. IMO its crap.
Juice defender is terrible. It kills your battery. well thats my experience...

Terrible app. If it does anything then it kills the battery... Brings android system to the top of the usage list, because it shuts off 3g and wifi..
Sent from my ADR6300 using XDA Premium App
Screen is still the top on my usage.
I have the paid version. It gives you the ability to lock items (like Pandora) "on" for data usage. Then, they don't get killed.
I had amazing battery life with it on my D1. Jury is still out on the Incredible. I'm still working through ROMs and Kernels.
I use it also. It has this new feature that you can tell it your local wireless and leave it alone. Problem is it doesn't work. Keeps shutting off my wireless when I'm using it! Very frustrating.
Also their developer is not very accessible. They want all issues solved through their forums. I hate that...The best software also has an accessible support system.
The one good thing I will say about it is it has the potential for taking over all aspects of managing your phone. A one stop shop. Just not there yet...
I used to use Juice Defender with 2.1 and found that it helped battery life. However, with Froyo, it just made the phone unstable. (It'd just sponaneously reboot sitting on my hip 2-3 times a day.) After uninstalling all is well.
A co-orker's Sprint phone had the same flakyness until he uninstalled JD.
Wild! I have never had random reboots. But, we all know how unique these devices are... even between the same model.
With warm twopointtwo, it doesn't seem to be turning on all the time... or warm is somehow killing it.
dbaps - are you still in 'training' for the wifi? It takes JD a couple of times to fully learn your location (based off of towers) and remember that as a wifi location. Check under the settings...it'll tell you what percentage of training it has completed.
Those of you who say its crap obviously dont have it configured correctly. I bought "ultimate juice" and when you go into the custom or aggressive profiles you can tweak everything until your heart's content! It still seems to shut off data when Im streaming stuff with slacker and connected to wifi, even though I tell it not to. Other than that it definitely will give you a few extra hours if you spend the time to configure it properly.
Terrible app!

There is no correct configuration to this app. That is why it is called "Custom". The reason it is CRAP is due to the reason you list as a problem among numerous other features that don't work.
Seriously, why have an option to automatically tweak CPU values if the option doesn't work with 99% of the kernels on the market, which also includes the STOCK kernel?
Yeah, it's a GREAT app!

True. For clarity's sake, I was using JD free so I don't know if any other version would have been better or worse. It's possible that the complex WiFi network at work (multiple APs per floor with a centralized controller) confused things.
My phone is a droid incredible, the co-worker's is a Sprint Epic. Different symptoms - he had phone lockups requiring battery removal to recover. Rooted, re-ROMed and still crashing until Juice Defender removed.
If you use Ultimate Juice and set up things correctly. This programs rocks.
It will turn on and off your data (3g and wifi) when you need it (according to the conditions you set).
It takes a little bit of reading and intuition, trial and error, and PATIENCE.
Use it for more than 1 day. Your phone usage varies day to day.
Again, read the text, THINK, and setup the conditions according to the way YOU need them.
I get at least 20-40% more battery depending on how I use my phone. I rarely charge mid-day any more and I can count on my phone having battery throughout the most useful hours of the day.
On light to moderate use, I get at least 14-18 hours. Just for fun, I once tested it and got about 29 hours before the battery hit 5%. That's with a little texting and a few phone calls. I use the stock, standard capacity battery as well.
SET IT UP RIGHT!
I've had no issues with JD running on 2.2.
Set on Aggressive. Only annoying thing is that I get the error notification icon for Weatherbug Elite every two hours because data is shut off.
First - I've got the most recent JD installed. The old one was kind of lame. People have made some good points, but there is a lot of incorrect information in this thread...
It works. If you are *NOT* actively using your phone, it will save your battery by disabling communication you don't need. I can go to bed at 80%, wake up 7 hours later at 79%, maybe 78% at the worst case.
If you are using your phone, it's quite nice - it comes on quickly - and manages my network well (at home, uses WiFi, elsewhere - 3G).
It's not $10.
My wife is using the free version and has had zero problems.
I've never tried aggressive, but maybe I will.
I cant comment on the CPU stuff - never used that.

I've never had a problem either. I'm running Skyraider 3.5 with incredikernal 2.6.32.27. I have the free version set on advanced. The best battery lift I've gotten with light phone use, texting, data syncing and browsing was 72 hours. Same use with stock rom and kernal my best was about 18 hours before I needed to charge. I know everyone is different, but that's my experience.

When I tried it back last Fall the paid version was indeed $10, its now down to $5. Which I still believe is way too much for this app. My 3g would not turn back on no mater what I did and yes I read the tutorials many times and had it set properly.

Perhaps for you. For me (stock ROM on my dinc) it made the phone unusable. Calling that observation "crap" or "lame" is convenient, but doesn't reflect the experience that I had (and which others had).
Again, with Android 2.1 JD did help a great deal. With 2.2, it didn't help battery life but made the phone crash. This was not a positive trade-off.
With froyo, I can go two days on my incredible between charges given light usage without it. Why put up with the instability just to get a few extra hours of battery life?
For example, I'm currently at 62% after 15 hours since unplugged with moderate usage of the phone, with WiFi and Bluetooth enabled. I could just turn off Bluetooth except when I'm in the car, but I doubt it'd buy me more than a few extra hours of useful life.
Juice defender has caused me multiple problems. Was the source of phantom call drops and sleep of death!! As soon ad I removed it, problems solved.

Also corrupted two SD cards, losing all my files, because of sleeps and reboot caused by JD. Does not play well with Z and HD roms at all. Works at first but soon became the cause of a lot of problems.

2g/3g/4G Juice defender beta

Anyone use this from the market?
I wanna test out the 2g/3g/4G mode but it's giving me a warning that it could break my data and not able to be restored so I'm too chicken **** to test it.
Sent from my Galaxy Nexus using XDA App
Yes. Swear by it.
There are plenty of nay-sayers, and no doubt you'll hear from them here. I wouldn't argue the experience they've had, but then, I don't see why they argue mine (and other happy users).
I had terrible problems with battery drain on my Epic 4G. I had a lot of crap running, keeping the radios alive all the time with little junk that was just fine updating in bursts every 15 min. when JD wakes up the cell radio for apps to do some traffic.I'm also not OCD enough to remember to turn my wifi on and off.
Anyway, with JD and my configuration, I sip electrons. Take JD away and... not so much.
Put it on the GN and it seems to be working just as well if not better. I see threads full of people complaining about battery life -- I'm easily getting a day and a half out of mine with moderate use (maybe 20-30 min total talk time, some internet, YouTube, 20 minutes of gaming, and other typical usage). Sitting on standby, I lose about 1% and hour.
When configured properly, I find JD helps a lot, chiefly by automatically managing the radios. Worth it.
But do you specifically use the 2g/3g/4G toggle or do you just have your profile set to turn data off?

Yeah, sorry I wasn't more helpful about that. I only answered your first question
I don't use the specific toggles. I just turn data entirely on and off. I didn't see the benefit of switching specific data modes.
Yes, 3G uses less power than 4G, and 2G less than 3G, but OFF uses the least!
Haha np, I just like to be able to get my emails and mms etc.. At all times.. But hate leaving 4G on..
Just thought it would be perfect to have a profile to turn it to 3g or 2g like 30 seconds after the screen goes off..

Juice Defender is, without a doubt, the worst app I've ever paid for.
I had problems with JD on my SGS but it seems to be working much better on the GN. Stops the battery from draining while I'm not using the device. The main thing I'm using it for is controlling WiFi by location. I only have a few apps enabled with the screen off so it shouldn't be using a lot of data.

JD worked great on my SGS2 and works same way on GN - thanks to JD I loose just 2-3% over night.
I don't know if it's bad configuration or ROM incompatibility for the people that complain about JD.
Anyway, I have seen that 2G/3G/4G option but didn't have time to look around after beta version, anybody care to share a link? I would like to see if 2G is good enough to keep my internet radio going, it's currently killing my battery, like 10-20% per hour. Is there an option to use 3G, but no HSDPA?
When idling, with properly setup JD schedules and triggers and auto-brightness also managed by JD, I get great battery life.

I may as well weigh in with my view on this, as an agreement with both sides. When I had JD Ultimate loaded on both stock and custom ROMs on my Gnex, I undoubtedly saw battery life gains when the phone was idling, and they were significant. However, far too often I would go to unlock the phone, and the touch screen would be unresponsive and I would have to battery pull. Not once has this happened without JD running. A couple of times a day with. So it worked for me, but the instability that came with it was too much to bear, so I uninstalled.

Yea I know it's possible, but I just like that JD manages so many things for me, like auto-brightness, radio schedule or that it automatically enables WiFi when I get home and disables it when I leave and can do the same with Bluetooth if I wanted.
Surely I will uninstall JD when I loose interest in its advantages or when I find a different app that works better for me or when I simply get bored with it.
I only had to pull battery once since I installed it, which is not that bad. If it starts to annoy me, I will get rid of it. But so far it's ok.
My issue is that I don't want something controlling my phone. Too much control. I can all those things myself if need be. Isn't that the whole purpose of Android phones? To have control?

This.
Except never had a crash or lockup, never had to pull battery.
I'm a flash maniac, hacker, and mod extensively. I run a lot of crap on my phone. JD does a great job managing things automatically so I get great battery life.
That is, JD ultimate... the free version is way too limited.
Only problem I've ever had is JD bring really slow to turn data on when I wake up the phone, after its been running fora long time (like into the second day). Fixed by stopping and restarting JD most of the time.
Rarely happens because I reboot at least once a day for one reason or another.
Arguing over whether JD is "great" or "crap" is so juvenile. The fact is it world great for some, not for others. This speaks to configuration differences, not JD. Is Supercurio's voodoo sound crap because it doesn't work on some configurations? Of course not.

To offer a different perspective, I don't consider something for which I control the parameters to be "not under my control". I'm not seeing how JD's behavior is any different than the phone automatically connecting to a wifi AP if you leave you're wifi on without you explicitly telling it to connect.
If JD simply enabled some vague power savings through turning the radios on and off, without knowing exactly what triggers the control, I'd stay far away from it too.
Sure, its turning radios on and off, etc. -- exactly as I've instructed it to. I'm in complete control.

I've been doubting myself too much

to the point where I'm thinking of returning my Galaxy Nexus. The phone is beautiful and slick but I can't deal with the battery life. I'm especially worried for when I go back to my University next week because I'm not sure if the phone would last while I'm going from class to class from 9 AM to 5 PM everyday and most rooms having low to no reception.
Before this phone I had the HTC Thunderbolt with the extended battery and it could last me the whole day while I was going from class to class and under heavy and constan usage (to the point where I never had to bother monitering it or caring about the battery). I would have auto-brightness on, GPS, Google Latitude, use Facebook app freeling, have Google+ uploading my pics as soon as they were taken, use Pulse, and be ALWAYS connected to 4G without worrying about the battery life.
Now with the Galaxy Nexus I'm forced to turn down my brightness, turn off GPS, turn off Latitude (you can see where this is going. Pretty much opposite of Thunderbolt), uninstall Facebook and disable Google+, minimize my usage, and use Wifi whenever possible to get through a few hours. I even uninstalled Google Voice today to see if that makes any difference. Really? Why am I crippling my smartphone? Why should I have to turn off 4G on a 4G phone to save battery?
I'm obviously an idiot for comparing a Thunderbolt that has an extended battery (2,750 mAh) with the Galaxy Nexus that has a normal battery (1,850 mAh). It's also my fault for trying to believe that battery technology would improve in about a year especially after the horrible battery life from the Thunderbolt; I thought that people would learn from other's mistakes. I thought that the Galaxy Nexus, Google's new and precious baby, would fix the woes from previous phones.
I've been following a ton of forums to find out if there's a fix and I've done a bunch of stuff (disable Google+, uninstall Facebook, etc) but there's barely a difference. Some people are suggesting that an update will come along to fix the battery but I'm tired of hearing that excuse. A software fix will only do so much. And 4.0.3 has been announced for a quite a while from Google. Why hasn't this phone been update to 4.0.3? Why did Google halt it from the Nexus S? Is there something that's running down the battery even more with that update? I don't want to go off topic but I just hate being kept in the dark and not understanding what is going on.
Here I am now typing this as I'm looking at my Thunderbolt while it charges. I'm planning on trying out a few ICS ROMs to see how they go. I'm just tired of second guessing myself. The Galaxy Nexus is a beautiful device, both software and hardware wise; the camera may not be the best but I love it's speed and ICS is just sleek as F. But I can't fully enjoy the phone with the mediocre battery life that I am getting.
I suggest stock 4.0.2 with ogdobber's jamesbond kernel which only has undervolt open and the gpu oc'ed. Probably need to turn off lte and stick to the CDMA. 3g CDMA isn't fast but it is passable and battery efficient.
Sent from my Nexus in Texas.
even if battery tech does drastically increase 1750 mah will ALWAYS still be 1750mah it may take up less space or create less heat.. Mah is a measurement of milliamperes per hour
Try Paul O'Brien's excellent MoDaCo ROM - very impressive battery life and for $9 you get access to the kitchen. There's an update due today which will fix a flaky call issue.
Alternatively, hang on for 4.0.3 which is likely to bring some decent battery life improvements and bug fixes (though wouldn't surprise me if it's out for the Galaxy S2 first). I used to get 2-3 days of heavy use from my SGS2, get one of those and wait for ICS if you want better battery.
And a last alternatively... shove one of these in your bag:

If your in places with no reception, put the thing in airplace mode or disable mobile data.
This phone gives me the best battery life vs my last 4 phones,... HTC hero, htc evo, Nexus s, and htc evo 3d...
Get an external battery. Since you are in uni I suppose you will be carrying around a bag anyway so it won't be too inconvenient to lug around. Just leave your phone charging during lunch and it should last the rest if the afternoon.

Go into your sstem/app folder and take off apps that you don't use. EVERYTHING you don't use. if you take a trip to that folder you're gonna see a lot of **** that you didn't know was there.
Do some cleaning and you should be fine with your normal usage. Also, try to flash a kernel so you can customize the governors and allow the phone to sleep more efficiently.
Coming from a thunderbolt, you should know how horrible battery life is for ANY stock android device...
There's no need to gimp your smartphone. I fluffing hate it when people say "just disable 4g, 3g, take auto-sync off, turn brightness all the way down, and only surf the web with wifi"
WHAT? WHY THE **** DID I BUY A 4G SMARTPHONE THEN IF I'M ONLY GONNA USE IT AS JUST A PHONE?

Also to put it in context...I'm using the epic 4g and I still have the stock 1500 mAh battery and the only time I lasted more than 4 hours on stock without having to charge was with a gngerbread leak.
But after a couple days of devs getting dirty and taking the time to clean up, your battery should last exponentially longer since people will have figured out what exactly drains the batter and how to stop it.
On the epic, it was the DRM. **** always ran in the background, then someone discovered it and about a month later it became so irrelevant since all the devs knew what code to get the drm to stfu until you needed it

to the point where I'm thinking of returning my Galaxy Nexus. The phone is beautiful and slick but I can't deal with the battery life. I'm especially worried for when I go back to my University next week because I'm not sure if the phone would last while I'm going from class to class from 9 AM to 5 PM everyday and most rooms having low to no reception.
Before this phone I had the HTC Thunderbolt with the extended battery and it could last me the whole day while I was going from class to class and under heavy and constan usage (to the point where I never had to bother monitering it or caring about the battery). I would have auto-brightness on, GPS, Google Latitude, use Facebook app freeling, have Google+ uploading my pics as soon as they were taken, use Pulse, and be ALWAYS connected to 4G without worrying about the battery life.
Now with the Galaxy Nexus I'm forced to turn down my brightness, turn off GPS, turn off Latitude (you can see where this is going. Pretty much opposite of Thunderbolt), uninstall Facebook and disable Google+, minimize my usage, and use Wifi whenever possible to get through a few hours. I even uninstalled Google Voice today to see if that makes any difference. Really? Why am I crippling my smartphone? Why should I have to turn off 4G on a 4G phone to save battery?
I'm obviously an idiot for comparing a Thunderbolt that has an extended battery (2,750 mAh) with the Galaxy Nexus that has a normal battery (1,850 mAh). It's also my fault for trying to believe that battery technology would improve in about a year especially after the horrible battery life from the Thunderbolt; I thought that people would learn from other's mistakes. I thought that the Galaxy Nexus, Google's new and precious baby, would fix the woes from previous phones.
I've been following a ton of forums to find out if there's a fix and I've done a bunch of stuff (disable Google+, uninstall Facebook, etc) but there's barely a difference. Some people are suggesting that an update will come along to fix the battery but I'm tired of hearing that excuse. A software fix will only do so much. And 4.0.3 has been announced for a quite a while from Google. Why hasn't this phone been update to 4.0.3? Why did Google halt it from the Nexus S? Is there something that's running down the battery even more with that update? I don't want to go off topic but I just hate being kept in the dark and not understanding what is going on.
Here I am now typing this as I'm looking at my Thunderbolt while it charges. I'm planning on trying out a few ICS ROMs to see how they go. I'm just tired of second guessing myself. The Galaxy Nexus is a beautiful device, both software and hardware wise; the camera may not be the best but I love it's speed and ICS is just sleek as F. But I can't fully enjoy the phone with the mediocre battery life that I am getting.

Battery lasts me all day on the GSM version.
Folks, powering an extra radio uses extra power.
Moreover, the longer your data connection stays active, the longer your radio is active which is an even bigger drain. Since the LTE Gnexus devices are powering 2 radios (CDMA *and* LTE) simultaneously, and the second radio isn't as efficient as the standard radio that's part of the SoC package, this means that you need to ration your data usage if you want your battery to last.
Again, on the GSM version this isn't an issue because the radio is built into the SoC from the ground up, as well as it being only a single active radio at a time (GSM *or* UMTS/HSPA).
Software updates won't change that. It's a matter of physics. The LTE version may see some improvements here and there, but no software will counteract the effects of having to power 2 radios constantly.

Lol its definitely not like that. Its more like buying a new eco lightbulb that you use just like your old lightbulb but your bill is $80 more. Wut? LOL
But nah my epic 4g lasts me the whole day with 4g on (no access to wifi :[ ), auto-sync for gmail (i don't use facebook so its always the first app to go), blah blah blah. The only time battery is a problem is if I'm in a no sprint zone and forget to make my phone roam. Other than that, its used as a smartphone with 3+ hours of screen on time (voodoo color allowsyou to edit the gamm values and what not so its able to sip less power for the same brightness if that makes sense)
Seriously, root your phone and if stock is your thing, just install a custom kernel. Kernels handle the voltages and frequencies andhow your phone interacts with certain things so a custom kernel will almost ALWAYS have been optimized over stock. You will probably see a muc better result if you flash a ROM and Kernel, simply because custom roms are made to work without all the extra **** running in the background that no one wants

Just to clarify, make sure you KNOW what you're deleting and make backups anyway, just in case something you remove from there causes issues with another application that expects it to be there. Sure, you can remove a lot (if not most) of things from system/app without harm, but don't just go deleting random things unless you are SURE there will not be side effects.

Battery Drain

Is there an app or way that conserves the battery power. The phone is still completely stock but it received a firmware update through Tmobile and ever since then the battery gets drained by 4 pm (after all apps are x-ed out and phone is just in standby) the batter drops to around 30 percent... what can I do? I don't think it needs a new battery since its only a few months old... suggestions?

I dont know how much you use your phone and weather or not you watch movies or download files with Wi-Fi alot but it could seriously drain your battery if you leave things like Wi-Fi, Bluetooth, NFC, Brightness Up, or use live wallpapers.
If not, I would recommend checking your battery against someone elses because I've had a phone before that had a bad battery that could explode and caused me to have battery issues. Make sure your battery isnt swollen at all and if it is make sure you take it out and dont put it back in and go to a Battery+ store nearby and I'm sure they got one for your phone (they come with warranty).
Well my wife and I have the same phone and it does it to both. I don't have signal in my job since they have a Verizon antenna and it blocks our t mobile signal so I don't use it during the day which means the phone is just on stand by for the first eight hours. I make sure I turn off wifi, blue tooth, GPS etc and close all apps....but by the time I get out of work it's at 30-40% power.... both phones were bought this April so was hoping it wasn't/isn't a hardware issue and have to replace the batteries....

This is where the world of rooting and tweaking your android becomes extremely attractive.
There are ROMs that last 1 day + ( that's 24h+ hours of battery)
Only need two things....
1. Patience - to sit, read and closely follow instructions
2. Guts - to take a dive and risk ruining your phone. (Which doesn't happen if you have number 1)

1. juice defender is a start.
The rest all needs rooting really.
2. Build.prop tweaks
3. UV with a custom kernel
4. Lowest screen brightness (doesn't require root)
5. Restrict yourself to 2G networks either using AOKP settings or a build.prop tweak
There are others but this is how I achieve great battery times mostly.

Why not try and find out what is using your battery up first? Try GSAM from the play store, its free for one, easy to use, it will show you what is draining your battery, there are a few paid ones as well, but try the free first , HERE is the direct link to GSAM.
or QR code, just scan it with phone.

That is a very weird situation and try a app that shows the apps using battery. Even check the stock android battery section in settings and see whats getting used. Your brightness should be first since it can really eat your battery if its turned up. I dont think its defective since both your phones are having the same problem but both my parents have the 4.0.4 firmware installed on their T989's without a problem and get decent battery power. I however am using a custom rom with kernel. Did you use the same battery for each phone? or each phone has the same problem with their own devices and their own batteries when getting updated to 4.0.4? If you used your battery on her's I'm assuming the problem may be the battery and you just got unlucky with a defective one.
P.S. I'm assuming 4.0.4 because thats the latest update to ICS for the T989 on T-Mobile.
The battery manager that comes with the phone identifies the display, but I've set it to lowest setting and have a dark background. And yeah both phones have their respective batteries which makes me think it's a software issue.. We just upgraded to the 2.3.6 ( I guess t-mobile is a but behind lol). But I going to try the juice defender tomorrow... It's just while I root the phone and get a custom ROM... (doing my homework before doing anything since it'll be first time)
Sent from my SGH-T989
Those apps wont really help, it basically does what you can do manually, turning off settings or putting them at low usage. Rooting is the way to go, its rather simple, once you do it, you will have wished you done it sooner. Trust me, I was in the same boat, I had just got my phone last december, the wife and I were in Vegas and my battery was horrible, I was taking lots of pictures and video, but my battery was dying. I had no way to charge it til we got back to the hotel, next day was same thing, horrible battery, this was all before ICS even was around for this device. When I got back home, I rooted my phone, to date, I have gotten a best 44 hours out of the phone. I ROM hop so I try out the variety, there is how to's and videos here and youtube, you will kick youself on how easy it truly is to root and flash. GSAM will show you in more detail what is using your battery the most, good luck with whatever you choose to do. There are many people here who can help you along the way, thats what this site is for.
Juice Defender will help a ton with you're screen being off for extended periods of time. Normally without it, I lose 30% at work without touching it. Today, I have lost 6%. The margin won't always be like that but it's a sizeable difference. Also, I have an app monitor application you can use to track rogue apps. There is also this app called Autostarts where you can disable an app from opening and it's really useful for apps that you don't need running in the background. Turning off auto sync will help as well IF you are okay with not getting every email in 5 minutes.

well actually it does save battery but it depends on how well you know your device
if you know you can manage it yourself then ok you dont need it but it also helps by turning off data when the screen is off
but really for most people its not worth it and i would highly not recommend it
I used it on another (older) phone and it helped noticeably and I bought the plus version.
On this phone, I'm not so sure. Newer phones seem pretty efficient in the way they turn on/off radios. Currently, I can see JD offering a little benifit if you use it to schedule your syncing times at longer intervals (and you get a lot of email/notifications), and using the night time feature to shut down sync altogether during the night.
On this phone, I've actually had much better results using some customized init.d scripts put together by someone in my other phone's forum. I'm still testing them out, so perhaps I'll have him post it here once I know for sure there aren't any issues.
on this phone, those scripts made much more of a difference than JD did. here's some screen shots of the last two charges. The scripts seems to help most with saving battery when the screen is off. I'm a light user also, and hardly used my phone yesterday.
What are your settings?

I'm on Darkside Evo rom (ICS 4.04) and the jedi ics kernal basted on 3.0.8
I turned JD off last night before I went to bed and when I got up for work this morning, my battery had dropped from 68% to 48%. With JD on, I usually only get about 9-10% drop. So I'm keeping JD.
======
*edit* I had tried that cpu sleeper app (old version I believe), and I think it messed up some things I had going before I installed it, since my batter life dropped off a lot. So I'm going to reflash the rom today and set everything up again without it. I see there is a newer version in the market, so perhaps I'll try that one later.
======
For JD, I use the customize profile, and have the mobile data option enabled (turns off when screen is off),
I have the wifi option disabled (since I have it off most of the time anyway). And you can't use wifi calling if it's enabled because it turns wifi off when the screen is off.
sync is at every 30 mins
Night mode from 12am to 6am
I don't use app control, since I didn't want data enabled when I wasn't using my phone
Also, go to the google play store app, and disable automatic updating. I only have it set to update over wifi only. And be sure to disable notifications in any social networking app like facebook.
and use dark wallpapers, since the screen sucks the most juice. Mine are nearly black.
with the jedi kernal, you can use antutu cpu master to underclock and undervolt the phone. I just enabled some minor UV and UC, so we'll see how it does.
I paid for JD a long time ago....before I ever knew about programs like gsam. And when I saw it woke my phone over 200 times in a work day on aggressive mode....I uninstalled it and will never use it again.

your experience differs from many, pretty much everyone else lol. but whatever works for u. but I'm almost sure that with proper configuration even with the data left on all day u'd get more juice. that being said I'm not u and I don't use your phone so I agree to disagree
well i never trust third party anti viruses and battery savers - for a belief that they are all gimmicks has somehow been implanted into my mind during the early stages of my xda induction. But following the hype all around regarding jb i have had tried it once but didn't notice any difference - neither did it make things worse nor did it make em better - so i gave it up and now believe that a power user has many stuff at his discretion that he could configure to his liking to make extraction of juice from his pack more or less suitable with respect to his usage patterns
just my 2 cents
why fix it if it ain't broken ?
Juice defender is for noobs who don't know how to turn off sync, GPS, data or wifi.

CPU spy and better battery stats will demonstrate that this app does not cause wake locks or cause you're phone to wake to often. All juice defender is is essentially a toggle for data. And I'm apparently not the only one with a positive experience with this app. I put forth an effort to not use it because I trust most the guys in these forums especially ASD's this was just one area where personal experience out weighed others. It's a free app. Heck, test it yourself. Lol. That's the real best answer for anyone.

Juice defender is for noobs who don't know how to turn off sync, GPS, data or wifi.

Anyone can turn off simple toggles. The handiest thing about JD is that it's automatic and easy to set up. I don't have to turn on and off all these various things all day. Set it and forget it.

yeah, it would drive me crazy turning toggles on and off every single time I touched my phone to look at something. JD automates things and limits how often your phone syncs if you set it up properly.
right now I'm sitting at 18 hours up time with 72% battery left. 37 minutes of voice calls and 14 minutes with the screen on. I don't use my phone much at work because I'm in front of a computer all day, so I typically get better battery life than most people who are out-and-about all day.
I just got this phone 2 weeks ago, and I was getting about 18-24 hours total for each charge.. Now that I've got some things figured out, using my init.d scripts and JD, I'm getting about 48 hrs on a single charge.
after this charge, I'll disable JD and see how the phone does. typically at night, my phone loses less than 1% per hour. so maybe 7%-8% battery loss over 10 hours or so. before JD, it was like 15-20% loss over the same amount of time. I figure that's a pretty good test since the phone isn't being touched at all. But I'll test again, just to be sure it wasn't anything else I installed (since I had been trying different roms and apps a lot).
I haven't installed anything new since the weekend, so the phone should be pretty well settled in by now. Next charge, I'll disable JD and report back.

Here's the thing. I consider myself to be a power user. Maybe I just don't know what some of these other options are. If there's a better way to do it I'm open to more education. I like to learn new things. So let's here it. What else can I use to turn off my mobile data when I turn my screen off to save battery. Something automated and easy to use.

I can tell u straight up if you're using JD to disable the internal radios and only turn them on once every 30 minutes or so you won't get as much without it to have 48 hours total time off one charge, u must be doing that, or having it switch to airplane mode inbetween certain hours. nI would also think u probably have location awareness on, and switch to WiFi at work.
