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.

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"

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

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.

1. Battery life sucks. I had to bring a charger to work. Battery life sucks so bad that I switched back to my Thunderbolt, a phone not known for its great battery life either, but at least I'm no longer a slave monitoring my battery use. I can stream music and browse or game at the same time without needing a charger close at hand.
2. The gnex screen is a disappointment, especially at low back light levels. And I thought that SAMOLED pentile matrix screens were supposed to be energy efficient compared to normal LCD displays, but I've never seen such a battery life sucker in a phone. Inverted apps and black backgrounds don't help.
3. CDMA/LTE Radio. Not horrible, and getting better. Pretty much all if my LTE problems were network related. CDMA has been flakier for me but the 4.04 update seemed much better for the short time I used it. All CDMA/LTE combo phones suck battery life.
4. Apps/Market/ICS. So many of the games I've purchased are incompatible with the gnex its laughable. I must have $50 of games that I can't play on my gnex.
5. No good car and home docks.
This criticism post isn't meant to rile up gnex fanboys. My intention is to give valid criticism for people doing research before buying a new phone.
The VZW Nexus is a high maintenance phone, which needs users to constantly monitor battery use, make compromises on how they use their phone, and need chargers close at hand, but there are no good charging docks. Many games are incompatible with the gnex too.
So due to the hassles of using a VZW Nexus, I've gone back to my Thunderbolt as my every day phone, and my gnex has been relegated to being a mini wifi tablet that has a charger nearby.

Battery life is increased with the 4.0.4 patch.
Games not working isn't the fault of the GNex, its up to the game dev to update their game to make it work in Ice Cream Sandwich.
Poor radio...that's subjective. I get great reception in my town. Its not necessarily the phones fault you get poor signal. Also, signal strength is improved in the 4.0.4 patch.
This phone may not have the most features forever, but that's the point. Nexus phones spur innovation in the other OEM's.
Sorry you're disappointed.
Funny, I came from a Thunderbolt and I thought it had decent battery. Will disagree on the fact that this Nexus is worse than that; it's been better (much better) compared to a Tbolt.
Whatever floats your boat though. One less battery thread then I guess.

What don't you understand? I'd be happy to explain it to you.
On my thunderbolt, I was able to stream the entire Super Bowl (commercials and halftime show too) over LTE with lots of battery life to spare. With my gnex, I would have had to put it on a charger or changed the battery some time in the 3rd quarter.
With my gnex I'm constantly making compromises on my phone use. Do I want to stream music or do want to browse or game? With my thunderbolt, I don't need to worry about making those compromises, I just stream music constantly, and browse and game without constantly monitoring battery usage.
With the vzw gnex, no kernel or rom yet has really helped the battery suck, but my Bolt on stock Sense sips on the battery by comparison. And as I mentioned in my OP, the Thunderbolt isn't known for good battery life, only in a head to head comparison with the gnex does the Bolt seem to have efficient battery use.
Do you still have a Thunderbolt? Go back to using that for a week. You'll be amazed at how much more use you'll get out of it compared to the gnex.

With all the "I get great battery life" posts in this forum, a contrary opinion is needed, especially when you see the screen shots with hardly any display use.
I get great battery use too, in airplane mode and on standby, but if I want to use the display and 4g, the battery sucks much much faster than the same use on my Bolt. That's a fact, Jack!

At first my girlfriend had her Nexus S updated to ics and immediately we noticed a huge difference in how long her battery lasted and she is the furthest thing from a heavy user.
So when I heard that ics ws being released for our phone my first thought was i hope that what she experienced won't be what i do as we have a better phone right?
Well I am sad to say on a stock but rooted rom I experience the same lack of battery life as her.
Now I am no beginner to Android and have changed all sorts of settings available and nothing syncs on its own and when I unplug my phone from charging in the morning I will need to plug my phone in at night before bed as my phone will be completely dead.
I have to say I am very disappointed in the battery life of thr the stock rom and hope some good kernels make it out to help.

Have you tried to find out which app/process is draining your battery? Better Battery Stats can help you identify what is using up your battery.
I had a big keep awake problem when i first installed stock ICS on my T989D. I did a full wipe of the phone and formatted my internal SD card (after backing things up of course), reinstall the same stock ICS and everything works great now. Battery life is about the same as before (stock GB w/ Synergy kernel), which is about 30 hours with moderate use.
Try CM 9. I get almost 2 days of battery life.

Though I am now on AOKP, I had great battery life on stock ICS as well. But, everything is subjective. How many email accounts are being synced? Do you have Facebook / Twitter / G+ updating every hour? Do you have news feeds continuously updating as well?
I have to agree with the poster above. Get Better Battery Stats and find the culprit draining your battery and work from there.
biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

I have a brand new T989D (I'm new to Android, former iPhone user) and got the ICS upgrade the day I got it (9 days ago). Battery life is terrible, I'm lucky if I get 10 hours of moderate usage. The phone also tends to run very, very hot. Sometimes apps freeze and all I can do is either wait or, in some cases, remove the battery to reboot.
I'm open to any tips that will get this fixed! I haven't rooted yet (no time). I think I will try those wipe tools and reflash the stock ICS ROM.
First post btw - glad to have joined XDA!

Thanks, although a lot of howtos seem to be for GB since ICS only landed 9 days ago. Also there's a lot of conflicting information, so I prefer this one:

Wait for kernel development. Its underway as we speak. It will make a significant difference.
Some battery saving tips:
- use juicedefender and set it to aggressive mode.
- use romtoolbox or other programs to underclock cpu frequency.
- also try using telus stock ics. Very good battery life.

Stock, not rooted, my battery life is great. Something is using your battery up, and flashing some exotic kernel isn't going to change that. The stock kernel works fine. You'll want to find the root of the problem. Keep a real-time (or 1-5s interval anyway) eye on the phone's current (mA) usage, and when it's high for no apparent reason, you'll know that whatever is sucking your battery is doing it right then. That should help you characterize the problem. I've noticed when my WCDMA/GSM radio signal sucks, so does the battery life, so I either turn off the radio or switch to GSM only when I'm in that area. If your display is what's eating your battery, well a kernel can't stop that. Turn the brightness down, leave it on auto-brightness, or just deal with it if you need the display on all the time. But if tweaking and modding makes you happy, by all means...

biggest thing draining the battery is the screen.
you can literally watch the battery usage drop 10-15% in a period of 10 to 15 minutes which is absurd when its set to low.

I have the same complaint. The "screen" battery usage is just unacceptable, especially compared to GB. My phone has been draining from a full charge for ~4.5 hours and my screen usage is 70% and battery is down to 65% with hardly 10 minutes of screen-on time.
I use an app called autostarts and you basically enable/disable apps that start running when certain events happen (phone startup, wifi being turned on, incoming call/sms/mms, other apps turning on, etc.). Just make sure you do your homework so you dont disable something critical. Hopefully this app works on ICS. You'll be surprised what different events make certain apps turn on automaticly. Screen, data/wifi, gps and bluetooth are the biggest battery drainers. No matter what Rom you are on if you don't keep control of those items your battery will drain fast. Keep ur screen on auto, let it go off @ 15 seconds ( you have to be pretty used to your phone for that setting not to annoy you), turn OFF your data or wifi when not in use. With bluetooth and gps...well u know that when you use them your battery is gonna drain faster than normal...just keep that in mind. Its all pretty much common sense.
I'm not going to tell you how much battery time I get cuz its nonsense. There are times my phone lasts till the next day and others Im charging it by sundown. Then again Im still on Juggs n Darkside kernel and Im gonna wait a bit still b4 I make the switch. Also don't go by what other people say on battery life cuz if you might not get the same results on that ROM. Everyone of our devices is unique and acts different. Everyone user uses their phone different. You can't define "light, moderate, heavy" use so don't go by that either.

After upgrading to ICS stock unrooted battery life sucked (5-6hrs). I did the whole remove battery, factory reset and still sucked.
Broke down rooted (still stock), downloaded batterycalibration from play, followed the instructions. Easily get over 24hrs before having to charge again. and when I say easily, I mean I still have over 25% left.

Bingo. Vastly different battery life between ROM's is generally BS. Every once in a great while one of these threads has merit but typically someone saying ROM X had "Killer" battery life is clueless and drinking the koolaid. Then a placebo effect takes place. And definitely someones "Heavy" use is subjective. If someone says they get a day out of an android phone they are not heavy users by my definition. It doesn't happen with heavy use. Perhaps the Razr Maxx or another phone with a very large battery but I've had 5 Android phones. If I get past noon it's because I am not using my phone that much and forget about a full day. It's never happened in the 4 years I've used google OS phones. Never.

I just got the Samsung Galaxy S3. So far I love it..... Except for the fact it has the locked bootloader. All my Androids have had full custom roms. I just like the user experience of AOSP much better.
I am an average or below average power user. Yesterday I took my SGS3 off the charger at 6am and with above average use all day (I was setting all my email and apps up and a few video google talk chats), and was able to make it till 11pm before the device shutdown.
With the SGS3 having a locked bootloader, and not knowing if there will be a workaround to get me a AOSP rom running, I was thinking about returning this device and getting a Samsung Galaxy Nexus.
Is the battery life really as bad as I am reading?
I am north of Boston and not in a 4G market yet, and even if I was I would most likely shut 4G off for the most part.
Should I hold out in hopes of a bootloader unlock workaround for the SGS3?
Thanks for any responses.

I'm content with the battery. One charge gets me through the day with what I do and want to do. When I'm home, I always have a charger to use so I only need the battery to last 8 hours.
I have the GSM model and I can easily do two days with a charge. In areas with bad reception this is reduced. However, I still would get 32 hours without a problem.
As long as you don't 4G whore all day, a full day is easy.

If battery life is important to you then check out the Power Saving mode on the GS3. You can activate in Settings or in the Notification Drop-down. Among other things it downclocks both the CPU and GPU. The phone feels noticably slower in some tasks but it can really stretch out the battery if that's what you care about.
Would I get rid of an SIII for a Nexus? I don't think I would. I love my Nexus and I love the fact that I'm already running JB, but the SIII is one nice phone.
As far as battery life, just the other day I had done 12 hours and it was down to 59% on my GSM Nexus. That was probably a little bit less activity than I normally do but still fairly normal. No video calls or anything like that though. But even with that, for me I've always found that I can get great batteries and chargers from Amazon for cheap and I always carry an extra battery with me just in case. I have one in my bag (gadget freak so I have my gadgets bag), one in my car, one at work. They hold a charge for a very long time too so it's not like I have to be charging them all the time.
What I haven't been able to easily find for the GSM Nexus is spare original batteries. I could easily find those in Amazon for the CDMA one but not the GSM. I like using my NFC and the spare batteries I have do not have NFC

you easily make one day. my average use is 1.5, sometimes above. i have never felt its consumption is weak or bad. if you can, get nexus. i wouldnt wait for anything software related down there in the food chain. hardware is not as important as people make it or manufacturers, who sell new devices every week, would wish it to be. google makes phones that withstand a solid 2 year run. try that with an s3. a fully unlocked and cyanogenmod supprted s3 is something else, but still, when key lime is out you'll be haunted again.

Well, I guess I'll be a downer. I have never been able to get over 8 hours with 2 hours screen on time, tried a few different rom and kernel combos. In my opinion keep the S3.
So long as you're talking about the GSM Galaxy Nexus, OP, the battery is praiseworthy. I bought a GNex from the play store shortly after learning that Samsung would all but abandon the GS2 with regards to future OS updates now that the GS3 is out. Battery is pretty much comparable, I'd say. I managed about 1 day and 10 hours on a charge a few days ago, with 3 hours of screen-on time or so. Some of that time was spent using turn-by-turn navigation as well. I think I put it back on the charger with 8 or 9 percent of the battery left. Friends who have the Verizon Galaxy Nexus report very different results when it comes to battery.
From what I have gathered from the OP he mentions that his SGS3 has a locked bootloader which probably means he has the Verizon version. I would think he wants comparisons to the Verizon/LTE variant of the Galaxy Nexus in terms of battery life, not the GSM version.
The reason I bring this up is that, from what I have read in the forums, the GSM GNex is far better on battery life than the LTE version so it would be an inconsistent comparison.
I've gotten 4.5+ hours of screen time with ease. Bone stock and no attempts to improve battery life at all.
On both the SGS and SGS2 AOSP ROMs (I tried many) got half the battery life that CheeseWiz got.

I have my Galaxy Nexus and I have noticed the battery has just been complete crap lately. Today for example my phone was at 50% and after a 2.5 hour long movie, my battery was down to 19%, and within 10 minutes from that I was down to 14%.
I can easily kill 40% of my battery in one hour driving to work by streaming pandora. I have tried:
CM10, Stock Roms, AOK
Different Bootloaders
Newest radios, older radios, hybrid mixture of radios
Different kernels with hotplug CPU (LeanKernel, FauxKernel)
I might as well walk around with a car battery in my back pocket. I have tried turning off LTE and its better but damn 3G is slow. The thing that pisses me off the most is my Wife's Droid RAZR (not MAXX) has a 1780mAh battery running an OMAP 4430 cpu at the same speed and running LTE all day and she gets a day of use almost out of her device.

My Nexus S was a great phone with great battery, and hell even my HTC Sensation was a great phone but I felt weird with roms that were not true AOSP because of kernel sources having to be patched for newer versions of roms. So I switched and got a GNex when it came out.
So the new Google Nexus Experience is walk around with a charger in your ass, its sad that Google honestly let this device out like this, When and you can look at the S3 or One S/X and that Snapdragon S4 dual core is much better on battery then this OMAP

Im about to just fess up and switch to AT&T, at least if you disable LTE you still have great speeds on HSDPA+ to stream pandora and surf the internet. I really only need LTE for Netflix, its even worse when your device uses more power than you are able to provide it while charging.
Turn LTE one and Stream Netflix while on a good car charger, it will just slow your battery drain, im about to drop the money on the 2100mAH battery on Amazon, the one that comes with the replacement door that makes the phone just slightly thicker. Anyone have battery recommendations

Issue with switching to AT&T is losing your Galaxy Nexus if you want LTE. AT&T's HSPA+ is plenty fast enough for Netflix honestly. Much faster than Verizon's 3G.
But thats up to you. Battery life on the LTE Galaxy Nexus just isn't that good.

I rather not drop the huge money on another phone right now. Think I am going to go with This Samsung 2100mAH battery for now and see if we get a new Nexus Product this year. If not that new RAZR MAXX HD is looking quite nice
There must be something else going on. What is your per hour standby drainage like? I'm on vzw and have the 2100mah batt. But Pandora consumes bout 6~8% an hour if I don't wake the device up to much checking emails and such. My idle sleep drain is about 1% an hour with gmail sync on. I don't have any other apps i.e. Twatter, Face****, G+ and so on. My last 11 hours in the caps.
good day.
I used to get great battery but not recently. I don't load my phone down with anything crazy because it is a work phone. I disable 4G and have WiFi always on. A typical day at work:
8am off charger
push exchange, gmail, twitter and Facebook widgets.
Before I used a Winner00 kang. At 1:30pm, I would normally have about 75% left.
Seems with JB I'm lucky to have 30% and 45minutes screen on time.
Its bad. I've changed kernels, ROMs, super wiped, radios. Nothing seems to fix it. I'm wondering if its Google Now or some app update. I've done battery monitoring stats and I'm getting deep sleeps and nothing unusual.
I have VZW 2100mah battery BTW.

Yeah I've been getting worse battery life...another thing you can look at is how good the signal is wherever you are. The weaker the signal, the more juice it uses. I realized this once I started attending a university.
I've started to bring my charger wherever I go now.
The CDMA Gnex are notorious for having terrible battery life. I personally can barely get a full days worth of juice from the stock battery, so the 2100 could probably get you by the day without much battery anxiety. But YMMV; I also don't use BookFace cuz I'm too cool for such silliness
I do use Google Now and its nice, though its not as helpful as Google made it sound, though being able to access it for other things like phone commands or searching is nice.
I have Exchange Sync for work, Two IMAP email accounts that are on Push via K9 Mail. Play store set to auto update.
I have a total of 42 apps on my phone, most of which are the default apps like calendar, people, etc. I will be trying out a new rom later today once I get my phone charged back to 100% and now that I think about it, battery has gotten worse after JellyBean.
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)

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)

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.
