I keep hearing some people claim how "great" their Vibrant's battery is. I am on my third Vibrant and battery life has been terrible on all of them. Just recently I noticed ~16% of my battery got drained for ~15 minute voice call. (The attached screenshot shows voice call using 27% but at that time my battery was at around 39%, which means the 15 mins took about ~16% total battery.) I just passed my 14-days buyer's remorse, so exchanging it (unless I want a "like new" one) or returning it are not an option. Any suggestions on how to improve battery life? I already keep the brightness on the screen to the lowest it gets.
Thanks!
Hmm that defintely is not normal. I would check with the store in getting another replacement. 15% drain on 15 min call is not normal for any phone.
There is a bug where if you power down the phone while it's charging, then the reported battery % is higher than actual. Perhaps the seemingly fast drain is a result of the reported value "catching up" to the actual level.
Edit: So I figured out where you're getting your numbers .
Still doesn't seem right though, did you notice the battery percentage before the call by any chance?

My rooted G1 had that same bug. Start charging it, power it down, power up and from completely dead it would show around. 24% in a couple minutes of charging. This phone I've noticed does it as well as newer blackberry's. Bizarre...
What I would suggest is draining the battery till it dies, charge it back up fully and see if you can have it happen again. Could've been a fluke.

looks like a bad battery reading to me.
Complete charge, complete discharge, and complete charge should reset it.
Yeah the percentages do need to be calibrated and sometimes they are off a bit, say 100%-90% actually often goes faster than 80%-70%.
The batteries are also partly responsible since discharge Ah is not a completely linear relationship with voltage (which is why the percentages need calibration).
I would say unless you have a rogue application on your phone eating battery it is more likely just how it is being reported.

So if battery A has x% greater mAh than battery B it does not mean A has x% greater battery life?

I'm having same issue. Battery life on my Vibrant is just horrible. I can barely go half a day until it's fully discharged and that's about 30 min talk time an hr maybe browsing apps and internet and a little WIFI/BT. Just for example I charged it after complete discharge and took it out at 11.30 pm last night, drove my brother to the airport and back around 1.30 and while it was sitting in the car and a few calls I made, it already went down to 74%, I purposely left it without charge till morning.... at 8am it was showing 47%... WTF!!
I have rooted the phone with update.zip, I have installed ATK and have Crazy settings on it.... one thing I don't get is that after it kills apps, they keep coming back every few seconds. Also brightness is at the lowest and no live wallpaper...
UltimateJuice by the way is showing 1.58 times, which is BS... right now it's 10.30AM and its down to 38%....
Any help would be appreciated!

Vibrant's battery life does suck, even with the supposedly power efficient processor and super amoled!!!!!!
Samsung has some more work to do. Hopefully, the froyo update can alleviate the problem!!!

Anytime the screen is on its eating battery. We have the best screen in the market. If you really want a conservative wallpaper use something almost all black or solid black. When a AMOLED screen is displaying black the LEDs are off.
For those "apps that keep showing up" those are due services that are running in the background. If you don't use the app often set the notifications to a lower time or set it to update manually.
If you've rooted there is a thread on "how to keep your phone quick and snappy" read it. Also fix your permissions through recovery. Rogue apps apps can drain battery.
after 3hrs of on & off hard using (minus extra long phone calls >45mins) I can pull 12-16 hours easily on one charge.
Look into things like eugenes vibrant 6 & JACs UV(under volted) kernel.
GL and car chargers are awesome!

Battery life on my Vibrant has been superb. You might need to change settings or something. This screen shot was for today with lots of calls and market shopping and I even watched a movie. I do not use a killer, yes I'm rooted with lots of tweaks to my notification bar. I'm using the spiritbomb lwp and its been great.

Unfortunately, the battery life on the Vibrant just sucks, compared to the iPhone.
I came to a Galaxy S and a Vibrant form the iPhone 3Gs.
With the same style of usage, the iPhone lasts at least 40% longer than the Galaxy/Vibrant.
I like the phone a lot, but am really unhappy to have to constantly think about how I use it, to avoid it dying on me before the end of the day.
Basically, with moderate use, it will last for a day, but if I go out after work and do a little texting or take a few pictures, it will die before I get home.
12-14 hours is really not good, since with my old iPhone I used to be able to last almost two full days without recharging.
Plus, the blocking of the camera at 15% of battery life is a truly idiotic decision by Samsung.
Thanks for your feedback! I am newbie in the Android world, as I come from the Apple planet. It just takes time to get used to it.
As for XDA App, where can I get it?

I am looking into the mod for the notification bar, specifically the battery. I have seen a circle battery with percentage, where do I get one?
XDA is your Friend
Search XDA for all ur app and theme needs, as for the Iphone being better on battery. I dont doubt its better, but from my experience and many family and friends showing me there iphones they are always tethered to a power source. Theres no better test than driving 300+ miles a day every day and coming back to the hotel and seeing my phone tell me i have been using it for 20+ hours and i still have 25% charge. I am constantly using my phone for calls, text, movies and such. Without my phone my wife would probably divorce me lol The amount of travel i do via plane, train and automobile is all the real world facts i need. Vibrant is a keeper.
Yes it sucks.
And under 15% it's not allowing me taking pictures!
Come on, I know I am under 15%, but I still want to take 1 or 2 pic!!
Hey guys,
Just got my Epic yesterday.. coming from the G1 with lots of experience loading and tweaking ROMs and dealing with same/similar battery issues.
After unpacking the Epic I used it and let it drain down to zero before recharging it; after a full recharge, I loaded up the 7 screens with widgets and ran a live wallpaper (fish). I didn't really use the phone much at all and the phone went from 100% battery down to zero in the span of only four hours!!! Geeze, you've got to be kidding me - four hours battery life?? WTF????!!
Back to the drawing board: I rooted it and ran SetCPU with some power saving profiles. Removed the live wallpaper and went to stock wallpaper. Set display power off at 30 seconds. Note that 4G remains off since there's no 4G in my area..
Couple of questions:
1. Is there any way to toggle 2G/3G like there was on my old G1? I know that was a power saver.
2. I didn't stop to read all the documentation yet (typical male, I know) but is there any way to wake this thing up from sleep mode besides pressing the power button? I can see that power button breaking for as much use as it's getting from me constantly having to wake this thing up!
3. My brightness setting is set to auto - since the display is usually the biggest drain on these things, is there a recommended manual brightness setting (percentage) that seems to work well for you and saves on battery power?
I'm waiting for the Seideo Extended Battery (just like many of you) and am wondering if I should keep the Epic since I'm on the Sprint 30-day Easy Return program.
Appreciate hearing from everyone!

I don't have 4G where I am. But, I have a all black wallpaper(uses less power) and unrooted. I easily get about 12-18hr out of my phone wit normal use(text, talk, and surfing the net with skyfire). Only thing that really kills my battery are games(Robo Defense can take over 30min to play one game).
Thanks for the reply - situation NOT improving
Thanks for the reply.. unfortunately, the situation is not improving...
I tried setting a Sleep Profile using SetCPU that would under-clock the CPU (using the stock kernel) once the screen dimmed and the phone went into Sleep Mode. Unfortunately, as mentioned in another thread here, the result was that the phone froze and required a battery-pull to reset.
I'm really starting to lose my enthusiasm for this device; as beautiful a display and as responsive a CPU/GPU, all of that doesn't mean much if you don't have good power management built into the firmware. At 6PM this evening I pulled it off the charger at 67% charged, it's now 8:35 PM, only 2.5 hours later and I'm down to 22%. I'm in a decent coverage area and get 2-4 bars of 3G strength so I don't think it's an issue of the radio being the culprit; in-fact if you check the battery stats it reports that that lovely Display is accountable for 78% of the battery usage! So I guess we're paying a hefty price for these 4-inch AMOLED displays!
I read somewhere else that the most recent update (DI07) has caused the battery performance to decrease; since my unit is brand-new it immediately went and installed DI07 shortly after the first boot-up so I have nothing to compare it to.. can anyone comment on that?
Thanks!
Chris R.
I'm sure custom ROMs will put performance / battery life on the top of the list but until then, I use JuiceDefender beta and have seen pretty good results with it. It shuts off data whenever the screen is off and since my screen is off a good amount (only use my phone if I need to check email, call, and / or text, which is rare when I'm at work). Other than that, yes, use black wallpaper, lower brightness to the min. in the OS and browser, and don't leave apps that constantly use 3G open (things like ebuddy, pandora, etc.). 3G really destroys battery life so minimal use of 3G data would maximize battery life. Maybe the devs can figure out a way to get at least one full day of battery life on this phone. I'm hoping that is the case.
As to your post, yes, DI07 has resulted in poorer battery life, for whatever reason. I was definitely getting a few hours more with the older firmware. I would not lose hope yet. As disappointed as you are (and all of us are, I can assure you of that), the devs are really starting to push out nice ROMs already, and in a few weeks to a month, I bet we will see some solid battery life. Hell, even 2.2 should yield much better results. Patience
Thanks for the tip!

DI07 has hurt my battery life substantially. In fact, my battery drains very close to twice as fast now with the update. I don't understand what they did. My phone certainly doesn't seem any faster, my display is dimmer, and battery life sucks. I'm going to have to go back to DG27 so I can use my phone all day. With DI07 it always dies on me by mid afternoon. With DG27 it was still running by 11pm at night without even a battery low warning.
juice defender ftw
also, use advanced task killer with low security settings to kill all the background processes. Set the autokill to when the screen turns off. This keeps everything pretty well managed and helps with battery as well
JUICE DEFENDER BATTERY!!! Saved my phone from flying out of my car window at 10 in the morning........
here is a link to a thread I started.
Sharing my juice defender settings. I also use ultimate juice.
http://forum.ppcgeeks.com/sprint-epic-4g/133933-sharing-my-juice-defender-settings.html
I can get a day and a half (or slightly longer) out of a single charge.
YMMV.
Hope this helps
Advanced task killer + Juice Defender. You could also get some custom roms and Kernals that would help boost it.
But that's your best hope. Keep off 4g, wifi, bluetooth, etc.

Look here- try stopping the DRM service and see if that helps your battery life with D107

Ah, the evils of DRM can strike in unexpected ways...
I wasn't really having a battery problem but I just turned DRM off, so we'll see if battery life improves anyway.
I had a whole long post here that got wiped with the xda disk array failure, so I'll just sum that up here too:
1) Use wi-fi if possible - it REALLY helps
2) 4G does not seem to use the battery any more than 3G, although hunting for 4G does and 4G coverage is not as extensive as 3G even in 4G areas. So it's still best to leave it off if you're moving around.
3) Dim your screen and use a dark, static background. AMOLED screens don't work like LCD's; they use more power the more pixels are lit and the brighter they are.
4) GPS also kills your battery - leave that off unless you need it too.
I think that's it. I get about 18 hours on DI07 (even before trying the DRM thing; maybe I can get to a full day!).
One thing I'm noticing after checking DRM - I've got Google Maps' LocationService popping up about every 10 seconds, and I can't seem to shut it off permanently. (I went into Lattitude and turned that off, not sure what else to do.) That can't be helping... anyone know how to get rid of that?
I'm using juice defender and a constant email junkie, but lite use on other aspects of the phone. It goes off charger at 5:30 am and I'm about 67% at around 3p. It then goes in the car charger on the way home. This has much better battery life than the Pre or the Hero as with both I had to turn off email to get it to last throughout the day.
I don't expect these phones to last days, but I expect any phone that I get to last the business day. I've always been one to charge overnight.
Wifi drains battery more from what I've read.

I've heard the opposite that wifi (as long as it's connected) uses up less battery than 3g/4g. Any of them will suck the battery dry if they're searching, so make sure you have a connection to one of them.
Hi everyone, new to the forum. Just started checking it out when the Epic was released and this is my first post. Anyways, here's my question. My phone's been off the charger for 7 hours and 17 minutes and it is now down to 15%.
Display 79%
Cell standby 7%
Android System 4%
Phone idle 2%
Swype 2%
I've gone into the display settings and I thought I had set everything up optimally. The brightness is always very low. The screen timeout is 15 seconds and the keyboard matches that. I don't know what else I can do to cripple the phone to get the battery to last longer.
I have had wifi on, 4g off, bluetooth off, gps off. Really all I have done this afternoon while watching NFL games is check my yahoo fantasy score, play 2 games of WordFeud, and check twitter and facebook. I purchased Juice Defender a week ago and it has been running all day.
Any suggestions for how I can reduce the drain from the display? My background is a black and white picture of a friend of mine, which I thought would help.
Don't get me wrong, I love this phone. But the battery life I've seen is just terrible. I'd love to buy the extended battery from Seidio whenever its available, at least that would make it last longer even if the settings aren't tweaked.
Do you have juice defender installed?
Yep. Its installed and running now.

There are only two reasons for your display to be using that much battery:
a) it's too bright, or
b) you're using it a lot.
If you're using the phone a lot, your battery's going to run out pretty quick and there's no way around that. If you're using it a "normal" amount, which to me means maybe an hour *total* per day of having the display on, then the other culprit is going to be your brightness. (Some would argue that's less than a normal amount, but think about it... you get a new phone, you're going to play with it for a week or two until you've seen all the cool stuff. But at some point you're going to start putting it away most of the time and just using it when someone calls you, you get a message/email or maybe to play a game or two while waiting for the train.)
Set your brightness *all* the way down, just as a test for a couple days. Make sure all the "power saving" features of the display are turned *off* (auto brightness, and whatever that "picture detection" feature's called, I can't remember). You just want the display as dim as possible all the time, just to see what happens. See what the battery usage says after a day or two of this.
My bet is that you'll see a drop, and then as you get into a more normal usage pattern it'll drop further still. You can raise the brightness a couple ticks then as you learn how to stretch your battery out.
Personally, my display is rarely over 15% or so of my usage. Today it's 29%, but it's a Sunday and I don't have anything better to do but play around on my phone.
btw, it's still the first day I've tried this but that DRM thing might be working. It's almost 9PM and I'm still on like 80% battery, and like I said I have been using the phone off and on throughout the day.
That has helped tremendously. I installed it pretty much when I got the phone and I'm able to last the whole work day with 67% left. (10 hour day)
I had searched previously and read some things about this "bump" charging stuff supposedly getting you many more hours of usage on a normal schedule.
Actually, guess I should preface with some background info. This is my first android phone, but I've been watching since 1.6 came out. So, the day I got my Epic it was rooted and I flashed Nebula ROM on it. I also tried out Epic Experience, but was more pleased with Nebula. Of course I'm running DK28 with the modem fix.
On to my question. What can be done to increase battery life on a fairly undemanding schedule, without causing the device itself to operate less smoothly?
I tried several of the bump charging methods I saw, but I'm sitting at 33% battery after 5:45.
I'm going to feel dumb if this is actually average and I'm just expecting too much, haha.
Thank you, kindly.

You can try calibrating your battery. If you don't know how, well here's some instructions:
To do this, all you have to do is let your battery completely drain. Then while the phone is off, charge it for around eight hours straight without turning the phone on (have it just showing the battery icon).
Since you are already at 33% or so, I'd suggest just letting it drain today, and have it just charge overnight.
I, too, am running the Nebula Rom, but I haven't tested it for a full day without charging it yet. So, you can try calibrating the battery if you would like to see if you would get any improvement, but in my opinion, 33% at 5:45 sounds great. I'd be satisfied with that.
Please let me know how it all turns out.
Hope this helps!

Thank you for the speedy reply, I will try that.
I wasn't really expecting 33%, but more around 50%. I've only sent three texts today on it (as I was trying to see how well it'd hold up) and so I assumed battery life would be fairly high. But I am also living in an area with extremely poor coverage, so bad that it'll start searching for signal if I move the phone 2 feet away. So maybe it is trying to acquire a signal often.
I'll report back in the morning. Any other advice/ideas would be greatly appreciated.

Well, there's basic things as well.
Check to see if Data Roaming is on, make the brightness Auto, no live wallpaper, no bluetooth, no GPS, No background data/Accounts Sync.
But you shouldn't have to do ALL of those. Just a couple if you haven't already to boost the battery a little.
And yes, searching for a signal could be the problem.
And only three texts? Nothing else? Maybe there is something wrong.
Tell me the results tomorrow after calibrating the battery.
I'm using midnight rom and I'm at 20h26m and 33% with moderate usage. You can try recalibrate and wipe 3x b4 install the rom. It might help. Good luck.

Alright, it's 9:20 EST and I'm starting off with 96% battery life. I'll gauge how it holds up through "normal" usage, which is somewhat less conservative. Wifi will be on nearly constantly, my signal will be weak unless I leave, autosync is set to hourly with background data.
I normally get about 12-16 hours on what I call moderate use.
I leave gps on all the time. I make ~6-10 calls a day for 5-30 minutes. I send and receive ~30 texts a day. I'll put an hour or two worth of internet time per day. (not watching videos)
I kill the drm and friend locator services on every boot. This helped my battery life a lot.
It does help to train your battery dragon occasionally.

Are you saying to turn Data Roaming on or off? I could come up with a reason it would help either way, so do tell.
Same thing with Auto brightness, I would think that actually uses more battery than a fixed lower/medium brightness.
Do people on here really leave Sync and GPS off?
Compared to these settings, I'm completely lazy, and still get good battery life.

Turn off Data Roaming. The reason being is that with it on, your network will constantly search for data, and that drains the battery. The brightness I am actually not sure on. I have had better results with auto rather than, say, 0%.
If you get good battery life already, that's fine. But auto-sync isn't really necessary in my opinion.

Alright, it's been 5:33 since it's been unplugged and I'm sitting at 68%. This is with wifi on the entire time, brightness set to auto, and data roaming off (no need for it to be on, I was considering toggling it based on my location in Tasker). Sync is on and I rarely have use for GPS in my day-to-day so that is off.
So I think the calibration as recommended by Acer1096xxx has effected the life of my battery for the better. Thank you, once again.
Hopefully this thread will help others out in the long run. I'll continue to monitor my activity and battery life.
EDIT: 57% as of 5 o'clock. Had to plug it in because I'd be going out tonight doing things. Overall, this is about the performance I was hoping.
Ok so I know I've posted about my battery before but I still can't get any relief.. I'm running JT .9 and geekniks 12/19 kernel.. the past two nights my battery drained 30% over an 8 hour period, with no one touching it! During both these nights I turned off Auto-Sync, and yes GPS and WIFI are both off..
Just now I had my phone charging and it was at 47%.. I rebooted my phone (just my normal procedure about once a day) and when it came back up a few seconds later it was at 69%!!! What gives?!?! Anyone have any ideas??
I have tried re calibrating the battery by deleting the battery stats method.. I tried calling verizon to get the battery replaced but was told that my battery is acting normal.. ive tried different kernels with no noticiable difference.. if i take my phone off the charger at 100% and send just a few text messages it will be down to 95% within minutes.. im at a loss.. I'll post pics of my battery use screen in a bit but throughout the night i only went 1% without a signal.
Maybe try *228 Option 2 ..... ??
I had a bout of some wicked battery drain and it was because I needed to update my roaming.....

I've tried that too.. question about that though.. I live about 30 miles from where I work.. should I update my roaming where I live or where I work or does that even matter?
Thanks for the response!
I have the exact same problem. Battery will drain for no apparent reason. I even bought a brand new battery, with still no luck. When I reboot the phone, as you said, something it will jump up 20%. I finally got fed up charging 4 times a day and ordered a refurbished phone. I'll let you know how that one works out.

Turn your 3G off overnight if you're not on the charger.
Wipe batt stats in CWM/advanced, charge until you get the full battery popup

I've tried wiping battery stats in CWM.. not sure how to turn off 3g.. Juice defender did it when I ran that but I didnt see an improvement and I didnt like the fact that it turned off 3g everytime my screen was off because then I don't get push on my emails.
Juice Defender has an on/off widget for 3G

although Juice Defender turns off your 3g when the screen is off, it also turns on your 3g for 1 minute every 15 minutes, so push notifications will be seen every 15 minutes (which I find totally acceptable to dramatically raise my battery life)
Just an fyi in case you didn't know.

yeah i was aware of that but i also didnt notice my battery life improve enough to use it.. if i would have noticed a dramatic improve i would have kept it.
At first I didn't notice an increase either, but after a day or 2. I get over 50% battery now
I just started charing my phone again.. it was at 70%.. i rebooted my phone and it jumped 14% to 84%... is it possible that the battery meter is just not accurate and when I reboot my phone it recalibrates everything and displays a true reading?
I can't remember where I read it, but I read that the phone doesn't portray an accurate reading. . If you charge to a hundred percent, the phone reduces the amount of power coming in but still shows full till removed from the charger, then it drops fast. Supposedly once it gets down to a certain percentage it starts charging again in bursts. This could explain why rebooting changes your percentage since the OS is showing the inaccurate reading.
I don't know if this is true or not, just something I read.
There's an excellent explanation of this here on xda. The thread is called "Your battery gauge is lying to you (and why that's not such a bad thing)" & I wish I could remember who wrote it so I could give him credit.

I called VZW's Customer Service and told them about my issues and they sent me a refurbished one. Just got it today, and so far, I'm having the exact same issues.
I am only here because a friend of mine is looking to get a Fascinate and I was doing some research for him.
I have an Evo, and I gotta say, you only lost 30% in 8 hours? Lucky you! The Evo, when it first came out would only last about 8 hours off the charger from a full charge, without touching it. The state of things now is a lot better. I can go 16 hours off the charger and still have 70-50% battery left depending on how much I used it.
The biggest changes have been custom undervolted kernels with HAVS, CPU underclocking with screen off, and "SBC" which probably just stands for super battery charge.
The SBC kernels for the Evo fix the issue of the battery dropping to about 87% minutes after taking it off the charger. It changes the charging behavior after full charge, maintains a trickle charge to hold battery voltage at 4.2v instead of burst charging intermittently once "full"
You guys might want to have your kernel developers look over here and probably see if some secrets can be passed along:
http://forum.xda-developers.com/showthread.php?t=876590
There's a neverending cornucopia of battery improvements over in the Evo forum and I'd suggest you guys go make a search over there for "battery" because tons of the same fixes are going to apply here. Good luck

I had a lot of similiar issues with battery life, and I found different kernels and roms have a huge effect on the battery:
Every StupidFast kernel I tried would *significantly* increase battery drain over stock. I'm talking 4-5% per hour overnight with the phone idle and not being touched or doing anything whatsoever - no GPS, no Bluetooth, no WiFi, no apps running, just sitting there.
Every BlackHole ROM I tried would do pretty much the same, although not quite as drastic.
JT's SuperClean was consistently very good on the battery.
On DI01, I was using SuperClean .4 on the stock kernel and getting a solid 24 hours on a charge. With DJ05, there is no stock kernel, and I had issues with SuperClean and signal strength, so I'm using the 12/12 kernel with the stock rom (debloated) and I'm getting 72 hours on a charge with conservative use and easily 48 hours with moderate use.
If you're using StupidFast, I'd suggest flashing one of JT's kernels or stock (if you're still on DI01) and see what difference it makes.
I finally am getting decent battery life.. I did a clean wipe and installed black hole 2.4 with jt's 11/29 kernel and have noticed a great improvement! Only problem is I get the audio popping with this kernel but I'll live with that as long as my battery is better.

So I've gotten my second refurbished fascinate from Verizon, and my battery life is still atrocious. However, how much does signal strength affect battery life? I get a dismal signal at my house, where my battery seems to drain like crazy. Can anyone confirm the relation?

They are directly related. If your phone if constantly trying to find a signal then this will drain your battery. Are you rooted, or totally stock?

i was at 55% at about 5pm yesterday after 10+ hours of battery usage, 1.5hrs of screen, and probably 2 hours of LTE (the rest wifi). i use juice defender so when the screen is off it generally cuts data signals for me. well from 5pm to 9pm my battery went from 55% to 1% with maybe less than 30 minutes of usage (all on LTE though). i looked and no unwanted programs were running in the background.
i charged it overnight, got up and after an hour this morning of ALL standby (seriously the screen was on 3m), i went from 100% to 87%. that would mean on 100% standby the phone would have died within 8 hours, which is definitely not right or even similar to previous battery usage for me.
i restarted my phone, recharged, and so far it has been on for 40 minutes and the battery is at 99% with 2m of screen time, which makes a lot more sense. so have you ever experienced something like this where an android OS restart helps your battery, or does it sound like i might have a bad battery?

Install Carat, it will tell you exactly what is draining your battery. I'm guessing something something is syncing in the backgruond and killing your battery.

Lots of people are having an issue similar to this with ATT. Is your ATT?
i am in fact ATT. sorry i haven't seen the other posts about it, have they broken through to figure out the root of the problem? any link to a thread about this? it's very, very odd. 8 hours of battery life is no good, too.

I seem to get it when I am in a poor LTE coverage area, which includes one of my offices. It is strange. "Cell Standby" will usually have the largest battery usage in your settings. My temporary fix is to turn off "mobile data" from the toggle in notifications, especially if you have wifi where you are. You can usually tell when the battery is being drained b/c your phone will stay warm even with no apps running and the screen off. The only other thing that seems to help is restarting it every day or so. When I don't have this problem, the battery life on this phone is amazing, so I don't think it's a bad battery. If you find out a better solution, please let me know!
I'm assuming you get off work at 5 and use the phone more. If so, turn off juice defender when you leave work. Since juice defender turns off your signal, you have to reconnect every time you use the phone. That kills battery more than anything

I would agree with your deduction. Cell standby is a battery hog. I use Wifi when I am at work and home. and HSPA+ everywhere in between. (No LTE in NH)

Doesnt that defeat the purpose of having JD? Has anyone shown than JD uses more battery than not having it at all?
Fyi cell standby doesnt actually use as much battery as it reports, its just incorrectly displayed on the battery meter. Hopefully there will be an update to fix it eventually. Google it if you want to fix it manually.

Cell standby is just a reporting bug. It is not actually draining your phone as much as it shows.
There are two separate problems. There is the problem on the international S3's where it is reporting cell standby incorrectly. There is another problem with some of the ATT S3's where they are continually connecting or re-connecting to the network where they have a poor LTE signal. This is actually using the battery. You can feel the heat from your phone when you have no apps open and it is normally cool to the touch. The only solution I have found so far is to turn off mobile data, and the phone will cool down again and stop draining battery.

Right. It's just cosmetic.
I don't have LTE in my area and my battery life is okay. I use wifi at my house and at work. I just think it could be better, but i am used to my dinc with my custom rom and kernel. Amazing battery life. I can't wait until we get some sweet roms and kernels for the S3. So far i am super impressed with the phone.

This isn't a problem that too many people are having, but there are enough that it must be a bug, at least for ATT. There is a toggle in your notifications that will turn off mobile data. I don't think it is enough to just turn it off and back on. If you are in an area with bad reception, you have to leave it off or the draining continues. If you find something else that works, please share with us.

I'm also seeing this issue; battery gets hot and drains quick in sleep.
I'm running stock, and only rooted.
I do notice when checking my battery that "Android System" is taking up the majority of my battery, by a considerable amount. Is anyone else who is experiencing the drain issue also seeing this under their battery reporting menu?
