I stopped by an AT&T corporate store to get a hands on with the Captivate. The salesperson there tried to tell me that the standby time on the device was 15 days if you kept apps from running by downloading an app killer. I asked if he really meant 15 days if no radios were running. He said "nope, 15 days is pretty easy".
Really, folks... what is reality here? Is it similar to other smartphones, where a day with moderate use is reasonable?
There is no way the phone will last 15 days in standby even with a good task killer. How can the sales rep tell you this if he only had the phone in store for 2 days?
That's a very good point... but he was very sure of his claim. I pulled out the "I'm very skeptical" response and walked away. Oh well, looks like once again, truth is in the internets somewhere, not in someone who should know such things.
Another element to this is whether an upgrade to 2.2 will increase battery life. I work away from any ability to charge and really need a phone to hold up all day.

Well, my N1 holds charge for about 1 day with moderate use. As soon as I play with the GPS and google's built in nav system I get maybe 4 hours worth of usage. Another issue I have with my N1 is that my car charger cannot keep up with the drain, so even plugged into the charger the battery percentage is decreasing. Sure hope the Captivate is better in that respect.
Froyo did increase battery life a bit but it is not earth shattering. The advantage of this phone is the larger capacity battery and hopefully a less power hungry samsung processor than the qualcom snapdragon.
I am sure within the next few days we will have some folks with more concrete consumption estimates.
i don't know... while the 15 day claim is a bit much, mine was fine with heavy usage all day yesterday on the half charge that it came with from AT&T... given that, i think that it should last 2-4 days easily with only light-moderate usage.
My battery lasts me all day. It's just marginally worse than my 3GS I think... My 3GS always had extra at the end whereas my Captivate seems to run out when I'm going to bed.
So... It lasts all day. That's really all that matters to me.
My battery has not been able to make it through the day. Don't know why yet. I have my email accounts set to 30 minute sync schedule, have Wi-Fi and bluetooth off. Don't know what is going on. Still researching. Will see how it goes for a week. Might be a bad battery.
i find that dark backgrounds help. Also keep unecessary things off and dl an app killa. I had a new captivate today at 10am and with its half charge and heavy usage it lasted me till 6
by heavy usage i mean constant surfing and dling shiz. I didnt use gps wifi or play a movie. also played that free mario game for bout an hour.
After about 11.5 - 12 hours of very light browsing (maybe like 1/2 hour 3g surfing, no calls, all apps killed with task killer every once in awhile) with Bluetooth and Wifi off I am at 68% left. This is with auto brightness.
I'd say if you don't do anything you might be able to get 3-4 days out of it. According to my battery stats 78% of all my battery usage has been the screen. Keep that thing off / or low brightness and you are going in the right direction.
i bet by standby att means the phone being not used and turned off for like 4 days lol

By dark, he means a background that has a lot of black in it. This is really helpful because the Super AMOLED screen on this phone turns off power to pixels that are black, so basically that part of the screen isn't using any power. A black background is almost like turning the screen off.

this, thanks for clarifying.
note: it further helps if you apply a static one.
I was able to listen to music for 6 hours at work, show off my phone (I only showed it directly to one co-worker - I had 5 other guys come to check it out after he told them about it lol!), did some light surfing, downloaded a few apps and generally fiddled around with the phone and ended up at 43% battery. Not great, but not terrible either. Screen was the big killer here. GPS and WiFi off except to test Layar.
We'll see if battery life improves, but it enough to make it through one day easily for me. Forget to charge it and it'll be flat early into the next day though. I'm a bit disappointed, considering benchmarks on the Galaxy S came up with nearly 8 hours of constant video playback. I think they had brightness at 50% and I kept setting mine to max to show off the screen and then forgetting to set it back, so that could be part of it. I was definitely expecting more though. I'm clearly not the most demanding user here, so I was hoping to potentially eek out two days of usage (just in case I forget to charge it).
One of the reasons I went with the Captivate instead of waiting for the Epic is that the form factor seems to be a bit more amenable to adding an extended battery. Hopefully we'll start to see some 2500mAh or even 3Ah batteries show up - even if it means getting a new backcover. THAT should just about do it

Also the Super AMOLED Screen sucks alot less Juice as well...
My friend has the Vibrant and has had it for about 4 days. He is a power-user like me, and he said with his task killer, he can run the phone for 2 days on a full charge. This is outstanding for a smart phone... I ordered my Captivate today, should be here on Wednesday so I'll also put this to the test!
better battery life is coming once devs hop aboard. Also, your phone will need training over the next few days so it can only get better from here for you. I also recommend just leaving brightness on auto detect. You wont have to play with it as much and forget it on super bright.
Some more tips:
idk if you guys like haptic feedback but i think its annoying as all hell. Turn it off to save an iota of battery.
Also tone responses for menu clicks? ANNOYINNGG turn that shiz off for a squirt of juice.
Lastly, unless you live by your email, turn sync off and only sync manually when ur curious about it.
I wonder about some of the widgets. I have Weather And Toggle Widget (which I prefer over Beautiful Widget), and have it set to update the weather every 30 minutes. Wonder if that's too often. The weather in Iowa can be very unpredictable and change quickly, but I'm inside all day so it doesn't really matter. I guess it's just eye-candy mostly.
I also wonder how WATW compares to BW in terms of battery consumption.
I turned haptic off (I agree, it was annoying). I turned the tones off, though I doubt that will affect battery life. I wish I could keep the tones for dialer and kill it for the keyboard.
EDIT: I keep reading about this idea that you train your battery (or device) to your usage, but I'm not sure that I understand/buy it. I could see perhaps something to do with the memory effect if these batteries are susceptible to it, but this idea of "training" it strikes me as very odd. Does Android have some kind of battery optimization algorithm that adjusts services based on your usage or something?
from what i understand, calculating battery life is like a guessing game. calibrating your device by letting it drain out and then fully charging it and draining it out again completely gives your phone an idea of just how long it can last on a single charge. Until you do a few cycles like this it will incorrectly display batter life percentage giving the user a false sense of security or panic. There may be more to it that has to do with the actual battery itself but idk the rest of the details.
and 30 min updates is a bit much lol. u should update like once a day and manually refresh if you need to know b4 u go out.
I'm getting very good battery life on my phone. As good as any iphone I've had and better than any of my windows mobile phones before that. I don't have any widgets constantly pulling down data though and only have my google account syncing contacts and calendars and an exchange account running.
Hello Everyone,
I'm fairly new to the forums as a poster, but have always lurked around to find out the latest and greatest about whatever phone I have. Now it's the TBolt, and I think I have read every single thing out there about how to conserve battery etc. etc. etc. as I've been dissatisfied with the stock battery until now. I've always been a huge supporter of Juice Defender and have ran that with much success over the last year or so. With the TBolt it seems as it really isn't necessary as I'll explain.
Everyone uses there phones differently and I understand that and after much testing with all the various roms/kernels out there, I've came to one conclusion. Das_Bamf 1.5 and Adryn Kernel 4.4.2 with ONDemand set at 245 MHz while sleeping that's it. I'm in a 4 LTE area but really don't need it so I always run 3g "when I need it on" (market updates, navigation, web browsing, videos etc...). So here's what I've had most success with...I don't run any app killers, juice defender, etc any longer. I stick with the brightness about 1/4 of the way down manually set, auto sync gmail and weather (for sense) that's it. I have the HTC widget for data (Mobile) widget set on my homescreen along side my vibrate widget. Seeing that you don't need data for text messages and or phone calls I leave it off 24/7 unless I need it, then I will turn on mobile for whatever I need (almost instantly 3G or 4 LTE comes on) and whenever I'm done I just switch it off.
Whenvever I'm home, I switch over to wifi if I need to but always leave data off. Over the holiday weekend I ran my phone right at 2 days on single charge on the stock battery with moderate use with phone calls, texts, web browsing, and market updates etc...This may be a no-brainer, but honestly I never really thought of just turning data off all the time instead of having Juice Defender or some other app work in the backround turning 3 or 4 G on and off thus making your battery lose juice. It makes sense, and I've finally been satisfied with the outcome of this simple idea. Let me know what you guys think! Thanks! i.e. Today about 30 minutes of talk time, 4 emails read and responded to, some web browsing, and a few text messages. Off the charger at 7 am and I'm at 91% now at 2 pm
the enter key is your friend
Your right that all phones are different, as are there users. You are running the absolute bare-bone of your features and thats why you are getting good battery. Having data off all day would increase battery life tremendously, probably more so than setting your governor profile to 245MHz when screen off but most people use their smartphones to retrieve data throughout the day.
Glad to hear that you found a way to make your phone work for your needs tho
My supervisor might have an issue if I leave my data off all day and didn't get push emails, meeting requests, etc.
Different strokes for different folks for sure.
I refuse to put this thing in 3G when I'm at home or work.
I live/work in 4G.
This isn't NASCAR, I feel no need for a restrictor plate.
If I was going to put the Tbolt in 3g then I'd just go back to my fascinate which lasted 2+ days with everything on 24/7.
The only reason I deal with this Tbolt is the 4g... which I believe iswhat kills the battery.

I suggest everyone try Juice defender...but the one u pay for. Its awesome. Its double my batt life, and has alot of settings to make it work best for u.
I got to try juice defender everybody saying it really helps out...I tried the beta but I didnt like it..all it did was turn my data off when the screen is off...
I am testing out a 1800mAh battery for my Epic 4G and will report the results.
I just got this in from a friend overseas and I am fully charging it now.
The battery does NOT require a separate cover, so this is nice. I'll let you know how the battery performs as soon as I can.
Right now I am using the Syndicate ROM along with Vision Kernel v1.1
I usually have my phone clocked at Ondemand with SetCpu with a max of 1300 and min of 200.
I also have profiles set for when the screen is off at 200min and 400 max. My brightness is down about 1/4. I have K9 mail poll every 30min and Plume twitter client poll every hour. Missed reminder usually runs along with MSNBCs air mail to pull any breaking news, and I am running Zeam Launcher.
On a full charge with the stock battery I can get between 19 and 30hrs depending on what I do. The 30hrs I can usually achieve with not much activity and the phone will usually be around 14% at the 30hrs. I do leave my phones data on all the time, so that is without turning the power off at night.
Anyway, that's just a little info on my configuration.
Will report new 1800mAh battery in the next day or so, or as I go along throughout the day.

When you are done testing the battery can you provide a picture of it or maybe take a picture of the battery in the phone. Thanks.
So here are my pictures from my battery usage for the 1800mAh battery. Again, the phone is running the apps listed in the OP and The usage will consist of checking tweets, texting and a few market update checks.
If you are looking for a battery like this one, I can probably get them for you at around $15 a battery. This all depends on how many people want them. While you're not going to get 50 or 80hrs out of it, I can say that i've gotten a few more hours out of it than the stock 1500mAh. In fact I have never hit a 40hrs PERIOD until I put this battery in. Now you may get more or less than I did depending on your usage, how often you text, internet usage, or running programs that check for emails, tweets, etc.
The 40hrs too are with the phone on ALL OF THE TIME. By this I mean I don't turn it off at night when I go to bed.
Let me know if you have any questions.

I'll post a pic later today. When I pulled the battery to take a pic I had to factory reset the whole phone (cause when I put the standard one back in I got FC all over). So it'll be tonight until I can get my camera to try and take a pic.
I guarantee you though that it is a 1800mAh battery.

FC close from swapping batteries? Ouch! I hope that was just a glitch, as I never plug in the power cord to charge anymore - I mean hardly ever - as I only replace my batteries approximately once a day and rotate between 4 OEM Samsung batteries.
It doesn't seem to have a charging system like my old PalmOS Treo
But I would be interested in one if swapping between the stock battery and the 1800mah one didn't play havoc on the phone and FC or screw up the battery metering system.
Thanks for your info - please keep us informed!
Which 1800mah battery is it? Do you have a link? I'd love to try them out if you're getting positive results.
Mabey it this one?

Yeah I checked out ebay, but there are a couple there.. and those Chinese batteries are notorious for being fake. If he said he's seeing better battery life I want the EXACT battery he got.
I actually did get one of those Chinese batteries. Didn't get it off of ebay though.I was skeptical at first but I thought.... Not like i'm paying $35 or anything, so it's worth a shot. But yes, like the pic.
Fits perfect, and have been using it for a few days.
@mouseglider... I was going to take a pic of the battery as requested, and that's when I realized that the digital camera wasn't working well for that, so I was like... I'll just pop the OEM back in and snap it. I didn't shut down properly and yeah, FCs. My fault probably.
I did have a backup from clockwork so it was all good. It did take a bit to restore because I didn't have a backup since the 17th, but all is well now and back to normal.
The only odd thing I noticed with the battery is that when I put the battery in, booted for the first time I had no data and it was on airplane mode. Found that odd, but I just turned airplane mode off rebooted and then it was all fine.
So far I have noticed nothing else besides that glitch and the FC glitch, but again I just yanked it then went... CRAP, i'm prob going to get FCs.
For the most part I seem to get 2-3hrs more on this battery. The test I did with the 40hrs was a basic light usage test. Not much internet usage or phone calls.
I will be testing it though with a longer twitter update, longer email poll, and no MSNBC background update nor Pulse news reader every 12hrs.
We'll see how that works. I just changed the email push to 1hr instead of 30min and Plume twitter update from 1hr to 2hr and disabled airmail for MSNBC.
Osama Bin Laden is dead and that was the most important notification.
Hey can you post a way for us to get it. Need to replace mine thanks.

Wow that took some cahones for the one who tried the chinese batteries lol.
Wasnt there a huge thing about chinese knock off batteries exploding!
but 40 hours is pretty good for and for 15$
I know right? Took some cahones. Anyway the battery seems to be ok. I haven't had it get real hot, get all weird on me or anything. Not only that, the Samsung battery says assembled in Korea, so I assume everything is going to be overseas.
As far as the link goes, I don't have one because I got it from a friend from china who does business over there with that type of stuff. I told him I was looking for a battery and he pointed me to this and I got it sent to me.
I can order a bunch from him, but i'd need to know how many because it does take about a week and a half to get them sent. This way I can have him get 5, 10, or whatever and I don't have to keep getting 1 here, 2 here, etc. Unfortunately shipping from China is not quick.
I there is a high enough interest i'll get them & anyone that wants one can let me know and you can pay by paypal once I get enough people wanting one to make it worth the shipping. Once I receive them I can get them to you for $17 which includes shipping as long as you are in the US.

I have bought 4 of those China batteries - 2 for my Moment and 2 for my Epic and had one of each lasted only 2 hours so I tossed them and the other one of each lasted for about 4 hours each - I actually did not buy them for the batteries, but bought them so I could get the chargers that they came with - so for me it was really no loss as they were really cheap - $6'ish dollars for one battery and charger - love the chargers!
I just use the standard stock Samsung batteries and simply rotate them - it works best for me and stays at 100% in the phone for at least 30 to 45min depending on light use - unlike when I charge them in the phone, and when I unplug them they always drop immediately to 96% to 98% even when I try to bump charge which is a pain in the butt and never works.
External AC chargers are the BEST!
Hmm,
I run less data update programs than the OP with a stock battery, Syndicate ROM, WIFI, Bluetooth, setCPU at OnDemand 1300/100, and Fancy Widget Pro (updates once/hour) all running 24/7.
I typically get anywhere from 24-48 hours of battery life. 48 hours has been achieved with mild web browsing, one 15 minute Google Nav trip, some emulator gaming, and various android games. I'd liken it to a medium total usage.
I had about 2% battery remaining by that 48 hour point.
If I turn off bluetooth and Fancy Widget Pro, but leave WIFI on, I can expect to have 70%+ battery left after 18 hours of use.
I'm not sure why it lasts this long, but I love it.
Thanks for trying out those chinese batteries.

However, this thread, says that all chinese batteries are inferior to the OEM samsung battery. But its a good backup battery for cheap, neverthless.
How many accounts do you have syncing? Brightness level? I copy many setups people have on these forums and the most i have seen in battery life is 18hrs using seidio 3000 mah battery. Stock most seen when it was new, about 12 hrs. What Apps can i use to monitor application usage?

As far as the previous poster, it seems as if they get a good deal of juice. I think it'll vary, but nothing should be THAT drastic I don't believe.
Yours seems to be drastic, or at least from even what i've seen from my set up. Right now I checked the phone, (it was on all night last night) and I have 71% left and unplugged at 12hrs...pushing 13. Now that is with the 1800mAh battery.
Again, ones internet surfing, phone calls and all of that makes a difference. I can say that with a few phone calls it'll drop and with surfing the net. But if you are running a 3000mAh battery and only getting 18hrs, you must have that thing running lots. I could see that usage with Facebook on, weather updates every hour, email every 15min, twitter updates all the time, etc etc.
What type of setup are you running?
Two gmail.com stock settings, facebook only contacts I have. No twitter.
Fancy widgets weather.
Brightness level down to bottom.
Calendar contacts mail on one gmail.com and only mail on the other.
How would you change how often gmail checks mail? I see no settings for it.
Still 30hrs even more 40 is exaggerated.

I finally decided I would take some extreme measures to aide the BL of my Androids. I have an HTC Inspire and HTC HD2 with Nexus S Android. The HD2 isn't all that bad...much better BL than the Inspire, but I wanted to apply this measure to both phones. Will it help? Only time will tell.
I started by removing all screen widgets. Then I sorted the screen icons so that a minimum of homescreens were needed...got it down to 2 homescreens. Then I deleted all widgets without apps not able to be opened through an icon. Then I went into Applications manager and cleared and stopped all non-used apps and services. I also deleted all duplicate services such as OEM email accounts and their associated syncing....using add-in apps for them. (example: built-in apps and widgets like Facebook, Twitter are uninstalled or disabled and am using another combining app like Seesmic. Same goes for the email app)
What I currently have is an Android iPhone. I'm using only icons on the 2 homescreens. And this makes me understand why Apple refuses to use widgets and stick with icons...to preserve BL. I hope this will improve the BL of my Androids because it is purely horrendous. And it is horrendous with all Androids I've tried and used.
Until the recently announced battery tech breakthrough is made available, this might have to be how Android is used from now on. But I doubt these extreme measures will actually help.
What is the difference between a widget and an application?
An application is a single, whole program package that is loaded into the phone. Examples would be Tapatalk, the default Calculator, and Angry Birds.
An application can have one or more widgets in it -- a widget is an interactive thing you can place on the home screen. It can give you information, and you can tap on it to change what it says. A good example of that would be Beautiful Widgets, or the little Android guy that tells you about how to use your new phone.

@Marty, how long was your battery lasting prior to the "Extreme Makeover"? Mine currently will last me 2 days. Admittedly, I've not loaded a lot of stuff on the phone yet, and I have the power saver mode start at 70%...but I only need to recharge every other day.
My desire lasts around 2 days with moderate usage. But on a good day (read: many boring moments), it's completely depleted by the end of the day. My biggest battery drainer is whatsapp, if I uninstall the app my battery will last a LOT longer.
If i really need my phone to last for a long time (when Im on a big trip or on a festival) I always use JuiceDefender with a very strict setting. This is a big help, but not for everyday use
whats the point? Where ever you sleep you have access to a plug/usb w/e so whats the big deal ? how hard is it to charge the phone every night? even thought my galaxy s2 hold battery for 40hrs+ i never need that :|
Ive dont the same thing, I also found some build prop and init.d tweaks that improve battery life.
my brightness is always at minimum, i have only one widget,
My battery could last two days BUT i use my phone a lot. like its on for 7 hours with 4.5 hrs screen on.

Hilarious.
ther have been many apps and disucssions on BL. heres some common tips.
screen to lowest brightness possible setting. background data always off unless using market. disable -use wireless networks- options, no gps, no location. also turn off *back up my data*. wifi always off not in use. screeen timeout no more than 2 minutes. turn off animations and transitions. setcpu with moderate settings (if you can do a screen off profile it will be beneficial but beware Sleep of Death.) no live wallpapers. minimum widgets or none. minimum homescreens or 1. startup manger. adfree. location cache app. and battery calibration to get the most juice.
the issues seems to be alot with hardware the Htc inspire and HD2 have 1250 Mah Batteries , which are very small.
If some people are just like me... I can kill at 1800mah battery in 5 hours even at full charge...
I do everything on my smartphone. So anything to save the battery is a good way.
I have the Galaxsy S II and I've managed to drain the battery in 6hours of usage and since I'm not near a power source most of the time then yeah I need all the juice....
I don't sit in an office or am near a power source 80% of the time. I usually carry 2 spare batteries with me and a charger for them just in case.

Whats the point??
Here is my daily usage :
Alarm goes off at 6:30am (phone gets unplugged)
Blahblah (at work) reply to emails and messages throughout the day, on twitter A LOT (plume premium)
2 calls approx 30 mins each
Play some games at break and lunchtime (Drag racing KILLS my battery, a bit of plants vs zombies, grave defence HD and maybe some pinball deluxe)
more emails and twitter
another 20min call
a little more gaming while im waiting on customers (1hr or so??)
6pm go home for 6:30pm
BAM! battery is at 10-20% and i need to plug it in again.
this is a typical 12hr day for me and im sure others have longer days and i would appreciate not having to rush home (sometimes) if im expecting a call.
so as far as im concerned anything which will save some precious battery on my devices is appreciated.
btw i have reduced my homescreens to 3 and only have 2 widgets running and that has made a great difference to my battery life (esp. on the DHD)

Basically kill factory and carrier bloatware and you are getting better.
One thing I was amazed about was the eBook reader that comes with our Galaxy Tabs, and suppose others too.. it always working even if you dont have or use it.
And remember, the screen is what takes most out of your BL, always. Lower brightness? Get a better ROM with no bloatware and maybe undervolt the screen.
Homescreens dont change a bit. Widgets do, if they update a lot.. more than that notification stuff do. Like if you use a antivirus or antisomething, just check of notifications.. check of any unneeded notifications.
Vibration theorically is what consumes the most.. but since its not as used as the screen, you dont even compare them. But every little bit helps. Check off keyboard clicks and hepatic feedback - vibrations.
Wifi, bluetooth, data... don't actually consume much.. actually it's better if you leave a service stable on, than keep sleeping and switching it. So leave wifi always on, no sleep policy. But when you go out turn it of so it doesnt keep scanning all the time (unless you want to ).
Just like any PC, the more you install.... Just check what you got going on, learn how to check processes and services that keep on all the time, and there are some utils to help stop some crap from starting up. I use ROM Toolbox and Autostarts.. some stuff get activated just because you plug you device to charge!
DONT use task killers... dont let anything like that keep running... and no, GMail push notifications wont use any batt. Maybe pop/imap emails always pollling will use some.. but probably nothing compared to the examples above.
Cheers for my 2 cents.
EDIT: and after Xmas, remove those animated wallpapers!
Is Juice Defender a task killer? Not really sure what is it but I've been wondering about that.
Juice Defender Ultimate has been giving me about a 1/3 more time with screen on max. Why is my screen on max, because I was trying to drain the phone. It's on about 40% now which is still pretty bright. I wouldn't be mad to get more life but I think 20+ hrs with moderate use isn't bad. I think the most I did was search the net about 4 hours total. But I was also, customizing, so it the screen was lit for a while.
This is a TMO GSII I'm talking about.
There are a ton of things you can do, but the truth of it all is that our 3G/4G radios pull so hard they drain the battery, which is why you were on the right track when you disable active since, Facebook and Twitter.
The main two things I do, is
1. add a widget for turning off 3G or 4G (If its in your area).
2. Installed Startup Manager ( it disables startup programs in the unseen background, (my phone is rooted)).
by doing these two things I am able to get 17hrs+ on a standard HTC EVO 4G battery. Keep in mind the more you use the Internet the more it will drain your battery. So I only turn the internet connection on when I need it or the app needs it.
*I also only use one screen and remove unnecessary widgets but I find that doesn't help the battery life all that much, (my personal Preference)
*When I or my sons game on my phone I put it on Airplane more which turns off all Radios including the Phone (call/text)
*Drawback to turning 3G off, you have to wait a few second for the internet to come back on and MMS won't download through your messenger unless have it one.
I've been off the charge for 8hrs and my battery life is still at 65%
Sorry to be long winded but if I know anything its battery life
Completely agree. What's the point. Either you don't use your phone for ANYTHING, and watch the battery last for 2 weeks (literally), or you use it so heavily that it lasts only 2 hours....
I was sick recently, and as such couldn't use my phone (I couldn't open my eyes without getting dizzy, and even closed.... still was). Suddenly my HTC Inspire 4G used only 20% of the battery in 10 hours. The previous day, heavy mail, "friendstream" (HTC's facebook/twitter/etc app/widget), listening to music (well, audiobooks) for about 8 hours, and I had only 20% left. And i've found that overclocking the phone to 1.3GHz helps more than any other tweak.
Don't get me wrong, I'm obsessive about using my phone *and* getting awesome battery life out of it. But the ONLY way to true "maximize" your battery life is to *minimize* your usage. But then you might as well buy a feature phone.
And I know a few people with iPhones. a 3GS and a 4 and a 4S. They don't get any better battery life than I do. Heck, they get worse. Even under the same type of usage.
For me, the problem isn't the usage, isn't what's running, or what's loaded (but it does help/hurt). The problem is that battery technology has NOT kept up with consumer needs, or IT development. Your battery is dying as soon as it leaves the factory. Your battery is dying every time you change it. Especially when it gets hot. your battery dies faster when it's cold outside. We need better energy storage medium. Period.
Buy the biggest battery I can find on eBay....
Use the fsck out of my phone all day and have plenty of battery left.
Problem solved.

<<<< What he said
I don't think the use of WiFi could be overstated.
On my Skyrocket, leaving Wifi on (indoors), it'll sip about 1% every hour. I go out and have 4G LTE on, it drinks up about 3% every hour.
Minimizing widgets also helps. I saw noticeably better battery after removing my facebook and Latitude widgets.
The screen also sucks up the most battery. Turn it off on every occasion. Just turning it off instead of letting it shut off by itself has made a difference for me.

Battery technology has kept up with usage. However, battery size in relation to the power draw, has not.
Compare the size of the back cover on your phone, with the size of the battery. Why is the battery this tiny little 2" square, when the phone is 5" tall and 2.5" wide? Why aren't batteries the same height/width as the phone? Why isn't the battery the same size as the back cover? Why aren't phone manufacturers optimising the size of the battery (meaning, making it as big as possible)?
It would be so nice if phone manufacturers would stop with this stupid "race to the thinnest" crap, and started:
- releasing phones that are actually comfortable to hold like a phone
- releasing phones with batteries larger than a pack of matches
your battery dies faster when it's cold outside.

Actually, keeping a battery cool makes it last longer, not drain faster.
Ok guys I have prbassplayer's blessing on this thread and he feels it may work so lets keep this civil and make it a helpful and definitive thread to help any and all users get better battery life. From here on this will be the only thread on battery life all others in q&a and general will be reported and hopefully closed. it is open to people in the skyrocket section on any rom and kernel combo. There are rules and standards that any who wish for help on this thread.
Rules
All requests for help must be in this format as this will help in speedy and decent recommendations.
1.Rom & Kernel Combo
2.How long you have been on said combo ex. 3 days and number of cycles will help considerably too.
3.Screenshots
1.Battery Graph
2.Screen on time
3.Better Battery Stats info (If applicable but not required).
4.general usage info as in how do you use your phone give us details into what you do through the day.
You can not suggest another rom.
this thread will not be turned into a best rom thread it is to help others get the most out of their current setups you may suggest other kernels but if you suggest another rom i will report your post and it will be removed.
My hope is that this will cut down on tons of threads and give everyone a good place to get help please guys lets make this section awesome like it used to be.
I think u should also ad to the op (nrm ) a few simple guidelines or places/things they can go and independently research. Not spoon feeding mind u, just a starting point. here are a few examples that come to mind:
1) Underclocking/governors
2) Undervolting
3) Wakelocks (pre-established thread anyone?)
4) Droidwall/background data usage & sync
5) CPU Sleeper & alternatives
6) Auto brightness controls (cm9, lux, etc...)
7) Wifi as alternative
8) H+ instead of LTE
9) Modem/radio choice
10) Sleep/display time outs etc...
And MOST IMPORTANTLY, avoiding apps like Juice Defender
I'll look into adding as we go thanks for the ideas bro

I'll start, because I just got the best battery I've gotten to date yesterday. WOO!
Note: I used stock charger to charge the night before, although no wake locks, i always restart in the morning. Dont know if it helps... I feel like it does.
1. CM9 Stable, InstigatorX 5.4.5
2. installed 2 days ago-ish
3. see attached.
4. Forgot to get a screen on time screeny... was like 2 hours. light useage. auto brightness
5. badass governor, used the cwm script to get both cores to be governed. 1.72/192
6. LTE/Wifi all day, baby. Mostly wifi.
7. there was a slight period of charge when i moved over some music. wasnt more than ~10 minutes of being plugged into my laptop.
8. exchange email on 15 minute syncing periods. Turned off push, as i can deal with the 15 minutes between emails... BEST. BATTERY SAVER. EVER.
9. gps off. didnt use it at all. I missed the key screen shots... I know. I only have this because i was bragging to my friend who's got a s3 on verizon and a sucky battery.
couple phone calls, probably 30 texts. it was pretty light usage these days. Color me impressed.
OHH! i have the nexus extended battery.

Not having bad battery life, but hey, it can always be better right!?!
First off, GREAT thread idea, it's a shame it hasn't really been utilized though. How about I start. I'm wondering a bit about how much battery I can save if I get rid of Google maps. Also, if you have any recommendations of a replacement for it if I do dump it. Even if I don't open the application the entire day, it is consistently in the top stats on my BBS reports. I'm not really sure of the effect it will have if I get rid of it though. I mean, if it is only going to get me another 40-60 minutes per charge, I don't know if it would be worth losing the convenient access to reliable maps.
Anyway, I thought I'd toss this out and see what everyone thinks.
I'm currently running Majicks Orthus One (quite happily I might add) and I've been on it for almost a week now. I generally don't use my phone too much during the weekdays while at work but, once I get home, the screen is generally on until I go to bed. On weekends, which is when I grabbed these screenies and BBS dumb, I am on WIFI most of the day, but I use my phone ALL DAY LONG even though I've got my laptop and rooted Kindle running CM10 sitting right next to me. LOL!
Other than the apps I've added (around 70 total), I've got it set up pretty much as if I just flashed it. By this, I mean that I haven't really done any battery tweaking. It's on badass gov by default, and I am utilizing the bln feature (I know it hates my battery, but I LOVE this feature). I get pretty good life usually (12-16 hours with 3-5 hours of screen on time), and I haven't really seen the media wake locks which are affecting others. Also, and I know I'm asking a ton (and maybe even being a bit of a battery miser considering I'm already getting decent time on my charges), but do you see anything else that should be a cause of alarm to me? Everything looks minuscule to me compared to Maps, but I know that there are many people who know much more than me when it comes to this stuff. So all thoughts are welcome.Without further adeau, here are some of my screen shots and BBS dump...
Thanks in advance! I look forward to hearing your thoughts.
Great idea. I'll contribute as well.
I'm also on Orthus-One, and whatever kernel comes with. One change I made was to change the governor to Conservative. Not entirely sure what that does, but I thought I'd throw it out.
I've been on this ROM for 28ish hours, so today was day 1. I've rebooted a few times. Can't remember how many.
I don't know that I've done a whole lot to reduce battery usage. Today I was on wifi almost all day, but normally I fluctuate between H+ and LTE (LTE near work, H+ most of the drive home, wifi at home).
Brightness is set at a constant ~35% with auto brightness removed. I don't use my phone for anything other than answering calls in the car, so that suits me.
I don't play any games that would be battery intensive, and only watch videos (from sd) when it's plugged in. Rarely listen to music, but that's likely to change next week on vacation.
These shots were taken about 3 hours ago. There's been another hour and a quarter of screen on time since then. I used my phone a lot today, as you can see.
Also, I don't know if it makes a difference, but I took the case I had off of my phone yesterday, and it doesn't seem to get anywhere near as hot. Probably a coincidence, but I thought I'd mention it.
Since it was mentioned above, this is all on a Standard battery.

That's actually not half bad battery life. I noticed a few things, though. One is the NetworkLocationLocator wakelock. Leaving network location on will chew away your battery like that. If you can do without a location service more often than not, I'd leave it and GPS off. I actually think network location is less useful than GPS--GPS doesn't use *that* much more battery, and it's precise. With network location, if a couple of wifi networks near you have "_nomap" appended to the end of their name, you're lost.
The only other PWL I saw was Avast. Personally, I don't think any of the "anti-virus" apps are worth the time it takes to download them. They sit there eating up battery, when really all you need to make sure your phone doesn't pick up a virus or malware is common sense. Only install apps from Play, Amazon and XDA (third-party markets will often put bootloaders and other bad stuff in their apps), don't click anything on shady-looking websites, and leave USB debugging off unless you need it.
KWLs all look ok. BLN is murdering you, but if the feature's worth the battery sacrifice, more power to you.
Alarms look fine, but keep an eye on Facebook. It used a ton of network data for apparently only being active 28s (according to the PWL data). Do you have it set to use push notifications or refresh on a short schedule?

Not a coincidence at all. "Naked" phones run cooler than phones in a case. Shouldn't be by a ton (if it is, get a new case), but a case, naturally, restricts airflow, which allows more heat to build up. I had to stop using my Otterbox Defender for that reason--the phone was just getting too hot inside the case, and I was starting to be concerned.

Yeah, after seeing maps eating up so much power, I changed it to not automatically update my location. I was using it cause the wife is a bit of a worry wart and she heard a story from a friend that their husband was in a motorcycle accident not involving another car and wasn't found for about 12 hours cause he fell into a ditch off a country road. Now, she thinks that if one of us ever get into an accident, that latitude is going to save us. Lol! I get the theory behind it, but her iphone only updates it sporadically anyway so it's not really worth much. I unchecked all location services, and I'll just turn on gps when I need it and see how that treats me.
Anti-virus is more for if I lose my phone. I like the remote wipe feature, as well as the Web and app firewall. Plus, it doubles as a security blanket for me lol
BLN is a power monger, but I love being able to have that option so I deal with it.
FB is a pain in the butt in general, but I haven't found an app I like to use in its place so I've just dealt with it. I do have it set to push notifications, but I've read that you think it may be misbehaving even when it's not set to push data, so I may just dump it and try fast for Facebook or friendcaster for a bit to see if I can deal with one of those.
I appreciate you looking into this for me as you are pretty much the battery guru around here. I was a bit worried that no one was looking at this thread cause it wasn't really being utilized. I don't understand why, when everyone wants to open a thread for battery life, they don't seem to want to utilize the one sanctioned by our mod. But that seems to just be xda in general lately.

If you're willing to, freeze/uninstall Maps and use MapQuest and/or OSMAnd instead. Both eat up far less battery, and MapQuest has basically all the same features. I use Waze as well, but that's more for speed trap notifications than anything else.

Just an FYI, you can have the Avast theft protection app (the one they tell you to give a custom name to) on your phone without the full Avast suite. Eats up almost no battery, and can be set to wipe upon X number of failed attempts to sign in.

Friendcaster and Tweetcaster have both had great results for me. The Twitter app's biggest sin is a stray alarm that'll hold you awake for 10-15 seconds every so often. The Facebook app, though, is (I can only assume) downloading ad data and sending usage info back at set intervals, even if you have it set to refresh every X hours. I caught on when I had it set to never auto-update, but saw that it was still using mobile data.
As far as mobile protection I don't use antivirus but I have Cerberus for tracking wiping and the like

First problem is you're using juice defender. Imo, that app does more harm than good on ics. It also looks like the gtalk app is waking you up way to much. If you don't use it, I'd say to delete it or, at the very least, log out of it when you aren't using it. Maps, like with my last setup, is killing you. I'd recommend following tj benders advice to me and either freeze it, or delete it all together and try one of his suggestions for a replacement.
Also, we're you charging at any point during that cycle, running at 384 for over 3 hours suggests to me that you had either charged for a while, or ya got an app going crazy. That is, unless your screen on time correlation is similar. Without the screen shots Illnevertell asked for, I can't really tell much more.
If ignorance is bliss, you must be orgasmic. Don't let your pants get wet and use that search button.

My apologies for not having followed thread rules on my prior post. I had just come from another battery thread that actually wanted BBS in zip form as the only post.
My prior BBS dump showed that my culprit wakelock was Suspend_Backoff. Searching I found the following thread:
productforums.google.com/forum/#!msg/chrome/rT0ewNsBx18/0_RqLGBQr70J
I unchecked "Enable Tilt Scrolling" in Google Chrome settings and recharged my battery to 100%.
I then left it on idle all night just like it had been when I generated the last BBS file dump.
As you can see the results are drastically improved. Went from losing 65% of battery in 5 1/2 hours to losing 25% in 9 hours. Also went from 5% deep sleep to 94%!
Still not pefect but definitely a significant improvement. Thanks for the great thread!
Spectre one thing is network location I would turn that off until you need it also that giant cliff dropoff I'm assuming was a reboot of sorts that went uncaught I know that for me I don't get reboots on jb I go to recovery and clear my caches first thing then I make sure to close every app as I'm done using it as far as bbs I'll leave that to tj as he is a wakelock god at this point lol

Google Maps, basically, is the answer. It's polling NetworkLocationLocator pretty constantly. If you turn location services off, you'll help yourself tremendously. I still recommend uninstalling Maps (usual disclaimer about uninstalling system processes) and using an alternate app like Mapquest, OSMAnd and/or Waze to clean up all of those Maps-generated alarms.
Beyond that, HD Widgets is definitely keeping you awake some, so you might want to change the refresh time on that. That being said, I can't imagine HD Widgets is doing too much damage to your battery life or people wouldn't use it.
Post up another BBS dump if you get a chance. Also, BBS dumps are a great way to tell if you've randomly rebooted (which, yeah, can chew through a ton of battery) because they'll differ from the "up-time" shown by your battery screen. Also, if you set your phone down at 9:00 PM and wake up at 7:00 AM, but your BBS dump says it's only been five hours since boot, you know you've got some random rebooting going on.
