Ok, my battery is weird it doesnt last long. it dropped from abut 95% to 70% over night, with checking email every 30 minutes with k9 and the mail app every 4 hours. My phone doesn't last very long either, I haven't tested it fully. I always keep charging it, when im in the house.
I bought it from T-Mobile and i could swap it. Should I?

Might be worth it, I have Friendstream updating default setting, Googlemail (although it's push) on at all times, browsing a fair bit (on mobile net and WiFi) and a few calls and it last 2 days-ish...I'm using a generic Desire on latest FW
Mine's the same. I didn't think it would be worse than my old BB Bold for battery life, but it really is very poor. I don't think you have a fault, it's just the way it is.
I wondered about closing background apps but I've read that having them open doesn't impact battery life. I do have a few background things going on though that will affect it, so maybe I need to consider if I really need them or not (frequent email syncing, contacts/calendar syncs, etc.).

Have you put the phone down for long periods in-between uses, or have you spent a fair time writing emails or just playing with it? I've spent a fair time on mine but not constantly, and no more than I used to with my BB Bold. I used to writing emails constantly on my Bold and the battery would last a good day, but until I'm used to this keyboard I won't be doing that on my Desire.
So It won't make a difference if i swap it? I also didn't do the standard charge at the start. Couldn't resist playing with it. So It was on charge while playing with it. Could that make a difference?
I'm in work a lot and I'm not constantly on it - just check for emails/SMSs every hour or so so prob spends a lot of the time in standby. I'm on it more on the weekends but it still lasts well into day 2

If it works otherwise then I doubt there is a fault that would cause the battery to run down but nothing else not to work.
Not charging the battery at the start is one of those things that some say makes a difference, other say it doesn't. With Lithium-Ion batteries I always thought they didn't need that initial charge, but I can't say for sure. Anyway, what might help is if you did a full charge then a complete discharge (use it until the phone turns off) then a full charge again. With older batteries at least, that tended to help them last longer.
There a a few threads on this alread here and on the Android Forums.
There is a problem where the phone when charged left on, only goes upto 98%. However the phone will soon drop to 90% and lower quickly, indicating the phone has not charged properly.
If you unplug and reconnect, it will go back to 100% but almost as quick as tying your laces, it will go from 100 to 98% and continue to drop.
It could be faulty batteries.
I was hoping the FW update would fix but it hasn't as I found out last nite.
Or should I just buy another battery?
I've been having similar issues,
I get much much better battery life without mobile networks on, and alot of application crashes/phone reboots to get it work like I expected.
Took some data:
1hr of phone in sleep mode w/ mobile internet on = 4% battery
1hr of phone in sleep mode w/out mob internet on = >1% battery
So I can get a good two days if I don't have any internet with moderate use, but about 16 hours with internet always on and moderate usage. If I really 'rag' it and use alot, I can get about 50% done in a few hours (not constant use either, just alot of google goggles mainly!)
This coupled with the crashes and reboot made me get an exchange, I'm just hoping it's better, and really hoping its not worse..
Wish me luck, I wish you all the same.
After couple weeks my original battery seems to last longer - I do with 1,5 days now (with some browsing, 3G, occasional GPS and bluetooth, weather & gmail sync, dl apps from market etc). So it might be true that after the initial couple weeks of usage and charging the battery performs much better.
Intrestingly T-Mobile promised to send me a new battery over a week ago. As it never arrived I called them and was told they dont have any... but they would credit my account with £20 to buy one. Today... I received an extra battery from T-Mobile!!! No idea what is going on - and if I still have that £20 credit in my account
I will give that new battery a loooong first charge, see if it helps.
what about the 3000 mAH batteries?
Are they any good and would it work for the Desire?

Won't help, once it's at 100% the charging will stop. There is no such thing as 'long charging' li-ion batteries or 'trickle charge' a li-ion battery.
You can try to do a full first charge (until the green light burns) and then fully discharge (until the phone goes off). Then fully charge again. This will calibrate the battery chip and make sure you see the correct percentage.
If battery life is still no good then it's because you use the phone too much. Read: constant weather updates, friendstream updates, push mail and other stuff that constantly use the mobile connection. Also turn off gps unless you need it.
Turning off those services and turning off the 'always on mobile connection' can double your battery life (read: standby time).
It's not something magical, it's completely normal. If you want the phone to do a lot, it will obviously use a lot of battery.
Just for the sake of it, put the phone in airplane mode. You will be amazed how long it will last.
It's the main problem with modern mobile devices. Battery usage and capacity are no longer in good balance. What we need is more compact batteries that have more capacity.
At the moment it's clearly a comprimise between battery size (thus capacity) and battery usage. It's up to you to see how much you want to comprimise.
And so far, with every HTC phone, after a few (radio rom) updates battery life increased.
And... what everyone seems to forget, when you first get your phone you will fiddle with it.. a lot.. And once you have it for like a week or two, you start using it differently. Usually ending up with better battery life!
Try to run it down to around 5-10% after each full charge, but don't let it go completely dead if you can avoid it. Do this a few times and you will notice an improvement. Plus of course, when the novelty wears off and you use it less the same will happen.
Back when I got my Touch HD it would only just last a day, but by the time I was on the upgrade path I could get 3 or 4 days out of it!
Just to confirm, I was a bit worried at first about the battery life of the Desire. The first 2 days I could only manage to get 7 / 8 hours out of it. When I turned data sync off at night, it still lost 40% of the battery .. doing absolutely nothing.
However as mentioned before, I'm now on day 6 and now I can easily get 36 hours of browsing / texting / calling 2 hours + / even playing occasionally games. At night, without data sync, it drops just 4%.
So if you're worried about your newly acquired Desire's battery sucks, It really needs some calibration. After a few days it'll work as you wish.
T-mob battery
Hmmm.. Not sure what T-mob is up to. They promised me a £20 credit to by a battery (they didnt have any in stock) then I received the battery in post. I called 150 and they confirmed the £20 credit is still there for the next bill...
I couldnt be happier with T-Mob! Besides this I got 100txt/100min, plus 60 min included to Eurasia, Internet and 40 free txt to Europe = all for £10 a month!
Now I just need a case for it... waiting for the PdAir one to come, had one for my Compact IV and loved it. Its the flip one that opens upwards not down, so wont mess with the hardware buttons.

I got my Desire on Tuesday, first use was on Wednesday.
Yesterday (Friday) I put the Desire into Airplane Mode - I deactived everything. Turned off WLAN, mobile Internet, Syncing off manually before I went into that mode, just to be sure. When I went to bed, I had 72% battery left. When I woke up...50%...seriously, what the f...?!?!
8 hours of doing absolutely nothing uses 22% battery?! It's really annoying at the moment, absoluetly unusuable unless I'm home and know I can plug it in any second. When I'm out, I don't even dare to use mobile Internet, because even without it it only lasts till I get home (no WLAN, no mobile internet, just using it as a "telephone"...).

You expect the phone to stay turned on without using any power? This isn't a dumb phone, it is running powerful components and 8 hours doing "nothing" is relatively long time and the power usage of keeping those components powered at idle levels is going to add up no matter what. If you can't bear to turn the phone off if you can't control your usage, carry a charger or battery you should have got a dumb phone.
Bear in mind that the full capacity of the battery won't be reached until several charge/discharge cycles have been done, especially when you are using the battery for the first time on a new phone or on a phone with updated firmware. I noticed this while flashing custom ROMs on a previous handset. I'm sure we will also notice improved battery performance when firmware updates become available.

Hey guys. I've been noticing a while that a lot of people on the forums get 12+ hours even on heavy web browsing, calling, apps, and texting. I usually can't get through a day of usage (probably 12 hours?) with my phone, and I carry 2 extra batteries with me. I calibrated my battery using the battery calibration app here on XDA and my screen is set on auto. I'm on Syndicate v. 1.1.1 and I use the stock battery.
It will usually last me 3-4 hours of 'heavy' usage (calls, games, texts) and maybe 5-7 hours of 'moderate' usage (when I'm at school, some texting, barely any internet usage, and a few calls)
Are there things that can 'harm' a battery? Some people say it's bad to charge a phone and use it at the same time, but I call people while its plugged in multiple times every day (probably a couple hours worth a day). Does that deteriorate the battery?
I'll post a screenshot of my battery usage tomorrow if that helps.
(note- I am a calling freak. So far I'm about 3/5 in my billing period and I've used 10,580 minutes. )
The charging and using not so much but letting it repeatedly drop low and get hot kills it

the one thing i would do to extend your battery life would probably be to take the screen setting off of auto and manually set it to the lowest brightness you can tolerate.
are you using the twilight zone 1.1.1 kernel? try using the genocide 1.0 seems to give me better mileage imho
I have noticed this even with my extended battery. I am actually going back to 1.1.0 with Vision kernel to test.
Phone calls kill this batter no matter what. Our specs for talk time is 4-6 hours I don't remember
So 3-4 hours on heavy usage is normal if I'm doing excessive calling?
Some days I have a 5 hour battery, some days I have a 20 hour battery - all depends on how I use the phone.
On the short days I use it a lot, I'm throwing attachments around in Gmail, files around in Dropbox, using 4G, and using my phone outdoors - read brightness up.
On the long days I'm using Juice Defender and Screen Filter - read brightness down - I'm mainly texting and powering the screen off asap, and getting in the occasional fb/tw check, and I'm hanging out in areas with stronger Sprint service.
My advice for elongating your battery - use Juice Defender and customise which the data controls by app. Use Screen Filter at about 60% and manual display brightness. Slide your finger left and right along the window shade to keep the brightness down. With the SAMOLED the more dark colours on the screen the longer the battery will last, so always pick dark themes on apps. If you're going to be in a low service area for a while toggle data off if it's an option.
Lastly, I picked a Zagg Sparq for this phone. I charge the Sparq in once or twice a week and then I plug my phone into it on the go on those days when I have trouble. Use the General port instead of the Optimized one. I played the multiple battery game with my G1..I prefer carrying around a juice box.
Have tried any of the "tricks" posted by Randomking?

OK, this Android OS bug is bugging me. I haven't even used the phone at all and it's 11.30am and I already lost 55% battery life, took off charger at 5am. Guess the culprit...
I really don't want to flash some custom ROM or root yet when a stock ROM is not out or start from scratch reset but I like everything about this phone and came running into its embrace from a NS4G that I thought had a terrible battery and craptastic radio. This is absurd.
So perplexed at the moment...

I've flashed to Starburst v1.5 and I have been getting 10+ hours with pretty heavy/frequent use.
Phone is sitting dormant really with just very little use. Has been off the charger since 6:30am and its not 2pm and I am at 88%.
just checking email and doing my fantasy football updates. Little web action to unsubscribe from some sites and that is about it. Definitely much better than yesterday. Rebooted and got my Android OS taking 30% of battery instead of 54% and got juicedefender running on aggressive. Seems like my battery is super good now.
Heavy use... About 12hrs. Live wallpaper, FB, maps, gps, 4G, games, etc...
Light use.. around 21hrs. I was still at 30% when I took that pic. I don't know maybe it could do 30hrs. Live wallpaper, FB, and text from time to time...
Running stock btw with no battery helper apps or juice defenders, and Im using the "Galaxy" live wallpaper. Still, even for heavy use this thing has lasted me. Very happy with the battery life.

Here's a way to calculate your expected usage. It isn't exactly precise but it will give you a decent estimate.
Gmail/contact/calendar sync on.
Battery consumption:
1) Screen off, wifi on - 0.5%-1% per hour.
2) Screen off, 3g on, good signal - 1% per hour.
3) Screen off, 3g on, bad signal - 1 - 10% per hour.
4) Screen on, minimal brightness, reading e-books - 1% per 8 minutes.
5) Screen on, minimal/medium brightness, web browsing/youtube - 1% per 4 minutes.
6) Screen on, minimal/medium brightness, games - 1% per 2 minutes.
Me today so far... I was at school thats why there wasnt much use for a while..

Either your phone is defective, or ... Come on! I can get 6-7 hours of youtube. Streaming music with the screen off must use much less battery.
Something else is draining your battery in a big way.
In all likelihood, you are used to gsm phones, and not CDMA. With CDMA phones, having a weak signal result is a HEAVY battery drain.
So, if you signal is kinda weak, in an office or other place of work, you are likely to burn battery.
My Sprint signal is very weak at work. What I do to save battery is switch to roaming.
My secondary roaming provider has a much stronger signal. Their cell tower must be much closer..
So, the battery drain while roaming is almost as low as with Sprint with a good signal.
For CDMA phones, there's paid app in the market called Roam Control.
Using that app to switch to roaming and save battery is the only way I know...]
EDIT: Ok, I lied... I just thought a bit more about the issue.
There's another way.
You can flash a verizon PRL instead of a Sprint one. Verizon usually has a stronger (and less battery draining) signal in my area...
1% per hour at idle with no use (idle) here.
Goes up with use.
6 - 8 hours of medium duty use (web music ect)
4 hours of streaming netflix
overall compares very favorably with every android device i've ever used (starting with launch day moment (nov 2009)
this is with everything on 4g, bluetooth , gps ect. with no effort to save batt. usually in a marginal service area.
Had my beautiful white S for 24 hours now. Overall very positive, except battery life so far. Drained 23 % overnight from a 100% charge. In only 7 hours I had NO activity. BT and WiFi on.
I hope this will improve very soon. That is a no go. Would like to hear from you about your experience regarding your new Xperia S.

For me, I removed junk I don't use, like foursquare. That alone made a huge difference. I also turn off data at night, and only went down about 4% while I slept.
Another option is to install something like JuiceDefender, which automatically shuts down data except switching it on every hour or so to allow for some syncs, then shuts it down again.
same as my arc, drained about 30% in the first day, with time it'll be better.
i was about to ask the same question. 7 hours seems about right, but i have been doing a lot of app installs, so I will give it time to settle down.
I use the XS in Hong Kong. If I use the phone online to play with internet browser, battery will be drained from 100% to 69% in approx. 1 hour. Is it too fast? Or it just a normal way when compare with SII or GN?

Ohh yes. U are soo right. Had my phone now for 4 days. The display uses an average of 70% of the overall battery consumption. It is not WiFi, calls, BT or any other functions. It is the display that drains. Will give it the weekend to see if it improves. If not I will return it on Monday :-( And my brightness is down on less than 25% so not much to do there.

Had an Arc for around one year. On a daily average the screen took about 55% and I had no problems to get a full day out of it. (approx 16 to 18 hours) and still 10-15% juice left. Now I get max 10-12 hours out of my S and NO juice left. Really disappointing. Even my old X10 did better than my new S.

Surely the HD display amongst other things, ie how you have your phone set up, may go someway to why your experiencing poor battery life compared to your Arc.
Try to disable Bravia engine and see if you notice any difference especially during the night.
My phone has the same apps as my Arc, actually minus few of them.
No autosync etc.
Basically it drains the battery quick, it's unacceptable. It behaves exactly like one of the older Arc firmwares, which was also draining battery like crazy.
Than they fixed it and it's still brilliant. My Arc on Flight Mode beeing just a backup in case of any problems, runs 3rd day on one charge, still 75% left.
I think S is just not optimized and it makes me mad.
Just got My XS yesterday I did one fully charge this morning . Turned off data at home, will not know until battery is fully charged by a few cycles. I love the phone irrespective of the flaws. I think may be see in a week or 2 where my battery settles.

You can use Profile Scheduler (free from market) and set a schedule.
I've set the schedule in which the airplane mode will be activated at 12.00 am and turned back to normal at 6.00 am.
By this way, my phone battery drains overnight just only 2-4%.

I actually agree with that tbh, and another thing is battery life all depends on how the individual uses their phone.
I had the sgs2 and alot of people said oh the battery life is rubbish but yet they had:
screen brightness on 100%
3g, wi-fi, bluetooth always on
live wallpapers running.
Plus they were using the internet for like 2hours
sending numerous emails
playing games
listening to music
I mean come on its a phone at the end of the day, its not a super computer or something or some nuclear powered device.
I nearly 2 days out of my sgs2 under moderate - quite heavy usage
because I turned my screen brightness all the way down
didnt leave 3g, wi-fi, bluetooth on all the time only when i needed to use those features, i never used live wallpapers and i dont send numerous emails.
when i had the play again people said the battery life was rubbish but again i got about 1day 10hours or a bit more sometimes based on the above mentioned info.
so as long as my SXS last 1day even I dont mind that because at the end of the day it has a HD screen so its going to use alot of power.
Okay so on my third day with the phone...
my battery is fine, actually...more than fine. I turn off my wi-fi/bluetooth/gps when not needed, and I don't run my battery heavy apps for a long time.
I also installed a task killer...I know it's in theory not needed, but I will see how it goes.
woke up around 7 today, used my wifi, used a battery intensive app (dream zoo , it's an addiction) for like 15min or so. Went for a walk, used the camera...a LOT, made a lot of panorama pictures. It's now almost 11:15 and i'm only down less than 15% I believe.
It's got much better battery usage than my X10 to be honest...but this is a high-end full HD phone, I wasn't expecting my battery to last so well D:
I will update again at the end of the day about how low it got, but I am pleased with it.
I haven't seen a battery life thread for the AT&T S3, so I'll start one.
Mine is around 13 hours with moderate use. I listen to podcasts for an hour in the morning (commute to work), read Pulse News and Facebook for about an hour at lunch, and listen to another hour of podcasts for the commute back home. By the time I get home, I'm around 13% life. I usually get the battery warning while listening to my podcast. In comparison, my GNex GSM gets 17 hours with the same use pattern. When I get home, I'm usually around 37%. Besides Samsung's and AT&T's bloatware, same apps, no widgets.
All told, I am very disappointed with battery life. I don't believe in underclocking my CPU in or disabling haptic feedback. I use the "Power Saver" mode, but only use the reduced screen power consumption feature (reduces framerates and brightness). WFI is always off (I don't have WIFI at work). I also disabled all of the Motion features. I disabled S-Voice (it monitors for the Hi Galaxy, and disabling also allows for a very responsive Home button).
I calculated my idle battery drain (unplugged when fully charged and not touch it) at around 4.4% per hour. That only gives 22.7 hours of standby! My Galaxy Nexus GSM can go at least 2 days (sometimes I forget to charge it at night on the weekends - also not used the phone).
Is it AT&T's LTE? Is it the Gsiff_daemon process? Is it TouchWiz? Or is it just my phone?
What's your battery life like?
You pretty much hit it right on the head. I had the extended battery from Samsung on my Gnex and could easily get 20 hours with moderate usage.
This phone despite using CM10 or AOKP with the JB kernel I never see battery life that good. I'm in the 14-15 hour range with about 3 hours of screen on time. That's with wifi off, and we don't have LTE yet. All in all, it isn't very good.

I average 32-38 hours with sleep and all. Usually around 8+ screen on time.

Stock? What features do you have turned off? Do you use WIFI exclusively? Do you turn off your data network (LTE/HSPA)? Did you turn off Sync?
I don't use WIFI, and I leave my data on (as it should be - just like I had it on my GNex). I also leave sync on. I understand that using these decrease battery life, but come on... not like this. The GNex faired very well, and it had a smaller battery. Besides LTE and an S4 (and the S4 should be more power efficient), there isn't much different between the GNex and the S3.
If I turn on the screen for 8 hours, there won't be enough for sleep time! It'll just die... if it even makes it to 8 hours...
20+ hrs with multiple accounts syncing at 1 to 2hr intervals, screen on time of average 4hrs. Heavy use. Wifi on all the time.
stock, rooted, debloated, super-aggressive power management I was getting maybe 12 hours with 2 hours screen time.
I saw you didn't believe in underclocking, but I started using Cpu Editor http://forum.xda-developers.com/showthread.php?t=1798765 and am loving it, can do 16 hours and 4 hours of screen time with no problems, will do the trick for me.

That's nearly impossible. What's your setup? Fricken hate it when people post battery life without explaining what their setup is.

My battery life with stock battery sucked too. Att signal sucks where I leave and waste 30% battery in that alone everyday. I got the Hyperion extended battery and loving it. Currently at 70% when usually I would be at 45-50%.

I hate to be "that guy" but I have a hard time believing anything close to this is even possible. Can you show us a pic of your battery stats?
Just use cpu tuner, It has profiles for each level of battery life so it gradually slows down your cpu's. You can get performance and bat' life.

my battery drains a lot when i'm on wifi even when my screen isn't on. I get on average 14 hours running 1.4 GHz
You have a faulty radio.
I consistently get 40+ hours off charger with 4-5 hours screen on time with a couple hours of browsing, 3-4 hours of music, texts, an hour of calls or so, playing casual games for another hour.
Stock. No hacks. No root. Disabled all unnecessary carrier and samsung apps and disabled GPS unless i need it. Auto brightness, 2 hours sync for weathereye, flipboard and gmail syncing all the time. I do mostly use Wifi at home because my signal at home is bad and that quickly drains my battery. At work my phone idles for eight hours at a 2-3 % loss with 3G on (i use my old SIM, i do not have an LTE plan, I am on Rogers Wireless).

You consistently (or have ever got) get 40+ hours off charger with 4 to 5 hours of screen time? Do you have your phone hooked up to a car battery?
I just factory reset (wiped data and cache) the phone and installed the apps I need (maybe something was badly configured or something) - did that yesterday night. Charged it up for this morning, and now I got 18 hours and still have 17% left. Screen on time says 1:38 hours.
This is on the same stock rooted and deodexed ROM. No hotboots either, so gsiff_daemon didn't rear it's ugly head.
Also no CPU Sleeper or any of these underclocking apps. I'm happy now, but wondering wtf was causing the problem... and will it happen again (after all, this is only day one).
I'm getting about 13 hours with 5 and a half hours of screen time. Underclocked to 1.2ghz and I have my own screen off profile. Great battery in my opinion

Phone finally died. Just over 19 hours. Heavy use towards the end because I was downloading and installing the rest of my apps from Google Play & Amazon App Store. Was also setting the apps up ( accounts, settings, and notifications...). Final screen on time was about 2 hours.
It's only been two days since I've had the phone, I've gotten about 14 hrs with roughly 3.5 hrs screen on time. I hate when I see people with 2 days off the charger and ridiculous screen on time. If you put the phone in airplane mode and ran just the screen you probably wouldn't last 10 hrs unless it was on low brightness. I had the Razor Maxx and I could get around 30 hrs usage with 4-5 hrs talk and 6 hrs screen on and that's the best battery life I've ever gotten on any phone with real usage.
I would like to get better stand by and more screen time out of this phone without getting an extended battery.

Nope. Stock battery. May be some of you have faulty batteries/radios/firmwares or run too much stuff at the same time.

No airplane mode. Cellular connection is always on even during the night. Only difference is at home i have wifi on instead of data.
Flipboard, weathereye and an appsales app syncing every 4 hours. Auto sync for google account and facebook. Automatic brightness. Almost all samsung and Rogers apps disabled (except for myaccount and a couple samsung apps) and motion disabled since i have no use for the gestures apart from being a novelty the first week.
No root. No hacks. I am actually amazed. This is the first android phone that has battery life on par with my iPhone 4 and the unparalleled smoothness. My HTC One X lagged, this never does even with a few apps installed now including games. I look at my iPhone and think "why do i still keep it? It is no longer relevant".
Ive got my UV tweaked just right on my ktoonez kernel and keeping my screen level as low as can be and I'm now practically making it to TWO days battery life! Plug in every second afternoon or evening after moderate use. Occasionally it doesn't last as long. Quite happy now. Oh and that's with this baby cranked to 1.809Ghz! But obviously tweaked to use that under strain otherwise using lower clocks and deep sleeping with 384mhz.
Got a 4200mah extended battery on way and can't wait to see how much I can squeeze out of it too.

My GS3 i747m lasts around 50-55 hours per charge cycle..
It is running stock Rogers GS3 ICS, not rooted, all stock. Battery is stock as well.
Not using LTE, using HSPA+ ("4G") with data turned ON with Sync turned OFF
(**NOTE: sometimes, the battery is drained due to poor reception, and the phone will use more power for the cellular signal.. In my case, my 3G connection in my area seems alright for the most part, about 1 bar less from full)
Power saving is turned ON. WiFi powersave is turned ON.
Moderated WiFi usage in 2.4ghz 802.11g-mode only.
Every night when I go to sleep, my flight mode is turned ON. (I sleep around 9-10 hours everyday, so the phone stays on flight mode for 9-10 hours a day)
In the morning, I turn the flight mode OFF.
Bluetooth, GPS both are turned OFF
Screen brightness turned 1/4 brightness
LED notification turned OFF
Also, I have a task killer killing ALL BACKGROUND SERVICES every half hour.
Without killing all the background apps, my RAM usage is around 600-700 MB out of 1.6 GB of RAM
Killing all the background apps brings the RAM usage to around 360 MB of 1.6 GB
Without killing background apps, my battery life is shortened even when the phone is on standby.
Do this, and your battery life is pretty good..
