I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.
There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.
I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.
You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

You just said your phone is at 36% eighteen hours after charging! Compared to the 0% I'm at ten hours after charging...I'm not looking for superb battery life at all, just somewhat decent. I'm actually bringing a backup feature phone with me to college this semester in case I can't resolve this issue, because I will need to use my phone both in the morning and at night some days

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.
The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.
There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.
I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.
Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.
You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.
2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...
i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.
I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it
Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge
Love the phone. Only complaint that I have is the battery life. I only get about 10 hours of normal use before it dies.
I have it rooted and I have installed Juice defender and setCPU. I have no idea really how to use either of these apps though.
Can anyone please help me to install and set up the apps that I need to get the best power/battery life ratio for this phone?
Thanks.
A really helpful tip is to use black backgrounds. This reduces the amount of pixels on the screen requiring power on the Super AMOLED display, and will improve battery life significantly. Tower reception is also a big one, just turn off mobile data when you get to a low signal area.
I suggest turning down the brightness to the lowest indoors and then bringing it up a little outdoors. 10 hours is really good compared to the 4 hours I got on my old 4g.

I second the black background.
I also installed widgetoid, created a widget with a shortcut to the mobile network settings.
I have Network Mode set to GSM only (Edge Network) throughout the day. This is fine to keep my email syncing and for phone calls. If I know I'm going to start browsing the internet/ streaming music/ etc then I go and set the network mode to Auto to allow 4G connections.
With a few phone calls and a little bit of internet usage I still had about 60% battery life left after 12 hours off the charger.
juice defender works wonders. Set profile to extreme. Choose carefully and let app do this rest. It auto shuts off data when not using 4 apps. I have been off charge 9:40 mitutes with 79% battery remaining. I've been on the market made a few phone calls, browsed the internet and getting and receiving text + emails coming in. Have settings GSM only until I need 4G speed. I don't need a charger because I get through the day easily.
Thanks
I just wanted to say thanks everyone for the tips! I know more is coming from other users but i'm new to android i switched from Windows Mobile 6.5 and android is better so far or atleast for the week i have had this device. i was getting upset with the battery life and always taking my charger with me(i never had to do that with my custom Rhodium. the black backround idea does work very well. I have also found if you set your backlight timeout to 1 min it helps a lot.

I can tether my Xoom for 2 hrs and listine to pandora over bluetooth for another 3 before it dies... my last phone could berly stand 45mins of pandora over bluetooth before crapping out
Always hated the idea of black backgrounds on beautiful 800x480 screens. Anyhows I had the very same quick battery death too and fixed it. One get Juice Defender, very worth while, second run device in portrait mode [I was an old n900 user so I had it in landscape mode, it did not like staying in that mode]. If things get really bad turn off the WiFi when not in use and change the autosync features to off or disabled. ALOT of power is comsumed by adware communicating with various entities while your away from the device. Genuinely suprused by the sheer amount of adware on the device, nearly ever "free" app is adware [meaning you pay with your usage pattern's etc]. YMV but that all I had to do to get the battery under control.
Im a moderate user and my battery is still going strong

Yep, I'm more than happy getting 10-12 hours of at-office use with WiFi on constantly (including M$ push and personal email) and a moderate amount of browsing during the day. I keep the brightness at "0" as much as possible.
Beats the pants off my N900 which would die in under 4 hours under the same at-office usage patterns.
OEM battery and charger is ~$25 or a Zagg Sparq2 (4 Ah, I believe) for watching hours of video and Angry Birds on those trans-Pacific flights.
You are doing something wrong guys. . .
I'm on a Vibrant /w Froyo 2.2.1 and a 1500mah battery that is now 7 months old.
Battery left says total battery life per charge is 23 hours, 15 minutes.
Now mind you I am a relatively moderately/heavy user. I have 5 homescreens with 15 widgets total on them that refresh every 2 hours, and an intensive live wallpaper.
I use the phone a lot for reading RSS feeds, facebook, texting, and LOTS of music. Total screen-on-time per battery charge is around 3-4 hours with Automatic brightness.
Obviously you have something going on with your phones if you are only getting 10 hours. My phone is also overclocked to 1.4Ghz with overvoltages and I STILL get this good a battery life with all my usage...on an old battery mind you.
Check for rogue apps?
PS: I have Wi-Fi on 100% of the time but NEVER use 3G/HSPA for data since I don't use a data plan. The Wi-Fi is connected 90% of the time the phone is on though since I am always at places with Wi-Fi.
Ive searched around and this seems to be a common issue, I tried the factory reset even the htc battery conditioning where you charge fully turn off then another hour back on for 2min off again and charge for another hour with no positive results, I read online some ppl are getting -1/-2 mah an hour I have never seen single digit in my phone.
I included screenshots of my battery drain even adjusted the app to read 1500mah, anything else i missed in settings? Also went into phone information in the Tests menu set it to auto instead of GSM, also with SetCPU I tried underclocking with little change to mah usage, running out of ideas...
Currently its rooted with GingerBreak, and CM7 with #48 nightly installed, any help would definitely be appreciated.
How many hours is your phone lasting on a single charge?
Lately between 5-7hrs one had about 8 and half hours a handful of times
it's true that if you constantly use the phone nonstop like watching youtube, browsing, playing games, etc. the battery won't last longer than 4 hours without getting an extended battery, heck just using moderateley the battery will be about 50% by the end of an 8 hour workshift, but what I found that will extend the battery life with moderate use are these...
1. Turn of wifi, bluetooth, gps, sync. (contrary to what ppl say on this forum I find that wifi eats way more battery than being on 4G)
2 Disable background data. (The only thing I actually need background data checked is to use the android market or maps when I need to, with it off it's a huge battery saver)
3 In settings choose to use only 2G (This will increase battery life 4x and Tmobile 2G is pretty fast, just like 3G)
4 Download Opera Mini (Since you'll be using 2G to save battery you'll want to surf the web with a browser that is super fast using slow connections, and Opera mini is second to none. You can always turn on 4G when you want to have fast video streaming but then you eat alot of battery again.)
5. Install Auto Airplane Mode (you can turn auto airplane mode on when you're not gonna be expecting calls such as at work or when you don't want to be disturbed, hell, if you just want to save as much battery as possible. Since Auto airplane mode disables the radio and data completey which is the number 1 cause of battery bleed with it on from a full charge unplugged you'll still have a 100% when you wake up your phone after a day.)
6 Install juice defender (free is fine)
7 Don't use Lookout Antivirus (I've found Lookout drains the battery quick, if you want an antivirus that doesn't eat the battery try AVG. I prefer AVG because I notice it does not drain my battery like Lookout.)
This has made my phone last more than a day on stock battery with moderate to light use. If I think of more tweaks I'll add later
This is ridiculous. If you have to turn off all those features, then don't even bother getting a smartphone.
My tips are:
1- Set brightness to auto.
2- Avoid Skype and other apps that usually appear as On going on the status bar.
3- Get rid of any task killer. They actually make the battery life worse. Don't worry about tasks running in the background, the OS takes care of them. If you wanna quit an app, try to look for a quit button by pressing the settings button when the app is on the foreground. Otherwise, just press the back button below the screen until you get back to the home screen (for some reason this seems more efficient than just pressing the home button.)
4- If you don't use IMs, get juice defender and set it to disable data when screen is off. It will turn data automatically on once you turn the screen on by pressing the lock button on the top of your device. Note that this is different compared to auto airplane mode, with Juice Defender you can still receive phone calls and text messages when the screen is off.
Last but not least, consider purchasing an extra battery and/or car charger.
Mine usually lasts for about 12 hours with moderate to high use. Almost all smartphones have short battery life if used heavily.

Yea that's awful. Do you by chance have your brightness set extremely high? And how is the cell coverage where you usually use your phone?
I think all of the advice above is valid and will save your battery. The question is to what extreme do you want to go? I tend to agree with donatello88 that there comes a point when you get so paranoid about battery life that you may as well not have a smartphone because you've turned off most of its features.
Get rid of any task killers, battery monitors, etc. They are simply churning thru clock cycles and that uses more battery. Set email, Facebook, etc to check for updates less frequently. Either use auto brightness or manually set your brightness to about 25-30%. That should b bright enough for everyday use unless your in bright sunlight a lot. Use juice defender if you like. And be wary of antivirus apps. I've heard some can suck ur battery dry.
If you do those simple things and are still getting only 5-6 hours then I'd be taking it back to T-Mobile ... unless of course you're on your phone without ceasing. In that case, what can you expect? Lol
Ok with the tips I just mentioned above, I got a chance to put it to real world test. I caught the bus to my son's grad ceremony and reached there at 4pm ceremony didn't start till 6pm so those 2 hours just surfing the web reading articles and forums I was down to 90% battery. Didn't know how long the ceremony was gonna be so called my sister on video chat using tango and spoke to her for about 20 minutes. Did some more browsing using opera mini set to only use 2g for another 2 hours, my don came out, I took some pics and video of him turned on 4g to video chat again with my duster for about 5 minutes, and after 4 non stop hours of consecutive use with screen on, I'm now at 71% battery life. I'm at the bus stop now on my 12 mile commute home and I'm confident the battery will give me more entertainment until I get home. Awesome! You don't have to believe me, just try out my tweaks and you'll be amazed.
Everyone thanks for all of the help and tips, today was the first day I saw 10hrs+(included screenshots), I had my screen on auto and after some reading saw that with CM7 it doesnt work well so I have changed it down to 20-40% depending on where I am, turned off background/auto sync only turn it on when I need it and uninstalled the app killer I was using also changed a few of the SetCPU profiles.
Im not really a heavy user just wondering if having 3email accounts set to update every hour would be a battery drain too? I mostly text/email during the day and talk about 1-2hrs depending how busy I am at work.
Again I thank everyone for pointing me in the right direction...unfortunately at home I have 1bar to none for service so I do depend on Wifi calling which im sure drains more juice, also at work since it in a high rise not too much cell signal so wifi on most of the day...

Hello risho,
I was having the same kind of battery life... After 3 months of research, I collected all valuable tips.
"Valuable tips" means: tips that do not need constant involvement from your side (you don't need to go switch on/off things, etc..) and also that leave you with a very functional phone (you have location when you need it, you have e-mails flowing regularly enough, etc...)!
With these tips, I am now lasting from 6am to 11pm and at 11pm, remaining battery is 10% at least!
Go and check my thread: [Ultimate GUIDE] Increase your battery life on Android!
Enjoy!
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.
Cheers! (Extreme power user).

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.
I can't get through half the day.
could you be more specific as to what you do on your phone? is your phone the international version or the USA T-mobile version.

Tmobile, stock everything and I had the battery issue on my first HOS. I just got my replacement and Im running the same apps, same calls, same eveything as the first phone but i get a significant more battery life. The battery on the replacement HOS lasted me the entire day, but I still carry a charger around just incase.
Superbattery?
My TMo One S battery life recently went through the roof for some reason. I can only attribute it to one of the following or perhaps luck:
I've been charging it at end of day regardless of charge but I finally let the charge get below 25% -- I think it got to 15%. Then I powered it down and let it charge 12 hours overnight.
I disabled all Facebook related apps.
Other than that I can't recall anything I did recently that might account for my new super battery. But I'm at 1d 4h 25m on battery -- most of that on WiFi granted -- and still have 42% juice. I'll take it!
I always have my charger because I'm a twitter whore. I recommend disabling any bloat ware or duplicate app like Facebook For HTC or Twitter For HTC. And make sure you change settings for each app you use and don't use.

Anyone use Juicedefender? My battery is excellent but if it can be improved then even better..
I'm using my phone very much, with Facebook and games and such, and I still get through the day without hesitate! I think it's wonderful
my battery life was poor on stock rom aswell. went trough a day only. had to charge every day. but now with noble v3 rom and being tiny bit more careful with use i have battery for 2 days
Battery life on this phone is better than most and I give it that. The only problem I have is the quick drop from 100% to 92% in a hour from little to light usage.

I'm on stock Tmo US and have been getting amazing battery life. I took it off the charger when I left for work at 7:30am and I'm at 75% at 8:50pm.
That's with quite a bit of texting, pics taken at work, and 45 minutes of web browsing while I was on lunch. Granted, I don't do Facebook, so that may help.
This is the first phone I've been lazy about rooting because it's worked so well so far.

I get decent battery life as well, but how do you manage only a 25% drop with over 12 hours of on time whic included a bunch of texting which keeps the screen on while u text and 45 min of browsing. Seems too good
I just got my One S less than a week ago. Love ICS. Battery life has been about 10 to 12 hours with medium amount of use. Facebook is disabled. I'm using active sync to sync to my exchange server and push frequency. (that continually goes out but that's for a different thread I guess).
I charge over night as I've done with my Dinc2, original Dinc, and all flavors of blackberry.
Last night I used a digital clock app while it was charging and in the morning at 8:30 where I unplugged, it had 100%. It's now just past 11 in the morning and with email, one short phone call and some light surfing, I'm already down to 62%.
I have noticed the phone is hot which means it's working hard to do something.
I have WiFi off and GPS off as well as location services. Should I return it for a new handset? Should I just go back to Verizon and get an iPhone?? Ugh.

What's your "screen on" time? Have you changed any connectivity settings, that may have increased your battery life a lot?
If the phone is hot then something is running in the background you should probably figure out what that is and disable it before you do anything. Now with exchange servers set up on your phone they do tend to eat some battery. That's universal though. Sounds like to do have a rogue app though. As for me this past Monday I took the phone off the charger at 430am and didn't have to return it to the charger til 11pm mostly because I was going to bed. I watched netflix, text, phone calls, Web surfed.... Love this device.

To you and the other person that asked, I think it really has to do with cell signal strength.
I posted those numbers after coming home from work where I have awesome cell coverage.
Today I've been home all day, and even though I'm on WiFi all day, my cell signal is horrible here. WiFi or not, it's still searching for a signal constantly so I've lost 30% in 6 hours with moderate use.
Now, as I said before, I don't use facebook or friendstream, but I think a lot of it is the radio constantly searching for a better signal.
I also think that either bad signal or just 3G takes a lot of battery.
I switched to 2G only just as an experiment, where I get a good signal almost constantly. This extended my battery life quite a lot. Where I usually had 10-20% left after a full day, I had 50% left with only 2G. I have also been using WiFi where available.
Can this be a software bug since there is such a big difference? I've noticed before that phone calls suck a lot of juice...

2G is known to use much less battery life in every phone you check it.
Take a look at GSMarena on phone specifications in the bottom and you'll see the great difference.
BTW, looking on the battery test GSMArena did for the One S, it's quite in good place for the 3G calling and Video playback but uses a lot of battery on WEB browsing, see here
Might be that we the ones with low battery are more surfing than the others...
I get about 24 hours.
2 hour screen use. No FB or twitter, only gmail sync
Some text, 5mins of calls, <2% no signal
When idle i get battery drain of <10mA using:
http://www.3c71.com
Battery Monitor Widget. Logging current consumption is the only way to get to the bottom of the problem.
I'm talking with the author to get the kinks worked out of the One S logging.
*but* for some reasons something is keeping the phone awake at times. current drain is then 70-80mA constant. Not been able to find the culprit, but a reboot helps.
Hopefully this was useful.
I had the same issue-downloaded 2x battery from the market and it is much better. ( I have syncing with twitter, fb, gmail, mobile life all enabled)
I could barely get through the day. Seems the phone does a lot when syncing etc and this stops that, or at least limits it to the interval of your choice. every 10 I believe with the free version.
Try it-I am sure it will help. (I also turn the brightness down as I am mostly indoors-and put it on auto outside-but that is just me)

Actually, due to the fact that every time I check the usage of battery screen is in top place (with Auto brightness all the time) and the fact I'm syncing with FB, Gmail, Exchange server and more, I guess the best thing to do is to lower Screen brightness...
