Battery life

Since I've installed the new software upgrade battery life has gone down. Can anyone recommend any settings/tips to maintain battery life?

not noticed any difference in battery life so far. are you playing with it a bit more because youve got the update? first day i upgraded mine i was using it a lot more and reinstalling all my applications and settings so the battery dropped faster. maybe give it a week or so until you settle back to your normal usage pattern.
main tip to increase battery life is to lower the screen brightness as far as you can. i think i have mine on about 10%. i can still see everything fine. the light is the main drain on the battery. also if you dont use 3G u can disable that. if youre in an area which has bad reception that can drain your battery faster because its constantly seeking and trying to get a lock. not much you can do about that apart from turning the phone off or putting it into airplane mode until you get to a better area.

I have the same troublem too,even Battery charge some time do some time don't

Nope, no problems. In fact today with mild usage of a few calls and sms's it has only gone down 9% in the whole day. I am satisfied with that.
BTW, there is already another thread for this issue. If a Mod can merge them, that would be cool http://forum.xda-developers.com/showthread.php?t=684651

wow i ussualy had to charge it every day, now with the update today os my 3rd day without charging but i have to charge it tonight

hmmm that would drop here in 3 mins of call
i figured out mine drops 3% per minute <---in call
and "energy saving mode" it lasts 15hrs

Hi
after GEN_EN 35, i'm having a better battery life than before.
my battery did great for just one day with simple usage, but after update i'm having about 2days life on. but with hard work and a busy day on call answering on BTooth and sms , little WLAN,.... i could finish the second day with light work today.
since yesterday morning, after about 31hours (about 13hrs work and remaining on standby) and did 2times restart, i'm having 30% battery remaining.

I guess I still long for my k790, that would last for 4-5 days for me, unless I was using the camera flash. I am getting battery drain similar to lock3k and indycar so I guess it's normal. I also browse the net most of the day and while driving between edge and 3g zones. I can get away with charging once a day so I guess it's ok.

yah. my battery is getting owrse and worse. I charged it last night before bed. woke up today it went down to 70% ... I obviously didn't even touch the phone, cuz I was sleeping ,,unless I'm a lunatic (which I hope I'm not)
so wth?

Come on man are you serious only 10% of brightness?? If this is true, I must agree that you will save a lot of battery life, however, you will kill the beauty of the screen! You have a WVGA resolution screen which is awesome!
So decreasing the brightness level this way will make you miss a great treat which is how wonderful the screen really is, anyway it's your call man but trust me your missing a lot
Personally, I set the brightness level to 70% and I have no problems with the battery at all! It works all day with heavy multi tasking along with taking pictures, many SMS and browsing the internet. Before I sleep everyday I charge it and that's it.
I think the battery on the X2 is very good. My only concern was that the software will stay unfixed for ever, specially after a lot of complains regarding the MR2. However, since I upgraded to MR2 this device is among the best I have experienced in my life, I'm loving it everyday more and more. And no matter how good other smart phones are, the X2's keyboard is simply unbeatable along with the other goodies it offers you.
In my opinion the best way to save the battery life along with enjoying your phone is :
Go to the setting>system>phone>band
And change it to GSM instead of auto, and if you want fast access to the INTERNET your better off with the wi-fi but don't forget to switch it off when ever your done.
Cheers

Good idea about switching to GSM only, but I have 3G on all the time and my battery performance is just fine. This includes having the SD card fix applied which disables power save mode on the SD card.
I don't understand how some people here are having terrible battery life.
Of course it is very important when you first get your phone to charge the battery fully and let it get to really low before charging again, then charge again for a few cycles the same way and it will be a very good performing battery after that. You can also refresh/maintain your batteries the same way. It may fix batteries that were not properly charged the first time, but they should be relatively new. As a warning though, don't let you batteries go completely flat. It's very bad for lithium ion batteries.

Thanks for the advice dude and what you said is totally true. However, since most users lack such knowledge and experience they will end up having a bad battery that's not using it's true capabilities.
So I think it's good for people to know how to charge there batteries probably from the beginning. Regarding the 3G and 2G networks, trust me man there are a lot of users that are only using the phone as a phone nothing more, so giving them the 2g option is the best for them.
But of course a person with a decent experience such as your self has no problems at all staying on a 3g network
Good day

Modern batteries don't require any loading cycles.
They are prepared already.

Yep, he's right! It should already be ready from the factory.
There is one thing to note, NEVER OVER CHARGE A LITHIUM ION BATTERY!
Unlike NiMH, they do not have trickle charge so leaving it charging for long periods of time or charging it over and over when it's close to full can actually damage the battery.

im getting these strange readings from battery meter
the temperature seems very weird as room temp is 28 (at work atm) im currently
charging the phone and it shows me max 4 degrees C but the battery is very hot

Terrible Battery Life!

I got my Vibrant a few days ago and as of today i can only get 4-5 hours max out of the whole battery and thats with heavy to moderate use.. does anyone else seem to have this problem.. im gonna return the phone and get a new one but does anyone else seem to have this?
I really dont understand why this is so bad..

4 or 5 hours of heavy use is about all I get. That is if I'm constantly messing with it. E.g. web, email, facebook,ect. However I think this phone has excellent battery life when I'm not constantly playing with it. Wifi definitely drains it quicker. And stupid apps like facebook. I periodically mess with my phone throughout the work day and by the time I get home I usually have about 75% battery remaining. I think that's pretty good.

THE BATTERY IS TERRIBLE. thats why i returned it, and the slow acrolling from screen to screen with stock software

I think you can only expect about 4 hours of awake time use on this phone. I haven't had much trouble with mine, I get about 13-14 hours per charge. But my phone its idle 9-10 hours of the day.

Then why are you still in the vibrant forums... move on...

I would think by now people would be use to the type of battery life you get with these types of phones. With heavy usage your not going to last all day just how it is until battery tech catches up to phone tech. I use mine a above moderate usage and some days heavy usage. From when I unplug it at 7:00am the battery is down to about 10 to 15% by the time I leave work at 4:00pm. Thats a lot better than my HD2, Cliq, MT3G and G1.

I agree 100%. Im seeing a lot of this. One thing I dont see is the "Vibrant Complaint" forum. Can't understand why ppl feel the need to come back in here if they dont like, dont have or feel they need to bash the phone from their experience. Get rid of the phone or keep it and be patient, its that simple... or am I missing something?!?!?

Im almost in the same boat, much better battery life then my G1! I can get from 8-8pm with moderate usage and music palying for the last hour. I was experiencing horrible battery life (8-2/3pm) when I was running notifications with Bloo 1.5.apk, auto brightness on, and Advanced task manager running. Now that I have cut the notifications from bloo (got gmail for this anyway), set brightness to manual setting, and got rid of the task manager I am regularly seeing, after bering unplugged since 8(its now 1245) and im @ 85%. Try trimming down the services you have running in the background and by an extra battery or a car charger.

Id like love to try mine out when i get it tomorrow because with
Mytouch Slide, i had Facebook, Gmail and all the usual stuff syncing and it lasted me close to 8-12 hours of Web, texting and just playing around with it throughout the day.
The Nexus One Was the same lasted me some good 10-14 hours a day syncing the usual stuff along with the weather and such. So Id expect the vibrant to be the same, or Else im returning it and thats the end of it. That also goes for lagging issues as well. And most likely get a different android phone or go back to the N1 and Switch Forums....

Have you ever owned a Smartphone before? Thats normal if you are using it heavily.

no its not normal.. ive used my MT3G with heavy use gives me at least if not more than 7-8 hours use.. what i dont understand is why the hell it takes so long for my battery to charge.

I get 6-8 hours.

I think 5 hours of juice is really good relative to your heavy usage. I always get 15 - 18 hours a day. That's with moderate use. Even playing a game of Armored Strike for an hour. This is the best battery i've had on a phone. I can easily get over a day and a half or even more once I settle down and stop using it so much more than I need to [ because I just got it.... ]

If this is what you consider to be terrible, I don't mind how terrible my battery life at all. I made a few calls, used GPS a few times, always listening to music.. some market downloads, pictures taken. SetCPU at 1000MHZ 100% of the time.

Disable Google Talk. My battery life was excellent (typically all day on full charge with heavy use). I signed into google talk one day and was lucky to get 4hrs before charging was needed. I deselected the auto sign in option and killed it in the running services section. Battery life has gotten so much better 70% after 4.5hrs.

i think the battery life for my vibrant is pretty epic. when i went to cm5.0.8 and cm6 on my g1 i calibrated the battery and thought i was getting really good battery life. then i got the vibrant. i could probably make it two whole days without a charge with how i use my phone (probably moderate-light compared to most on here).
but one thing i do agree with is this phone takes FOREVER to charge.

Hmm.....
Ok.....well I consider myself a moderate-heavy user...
On that note, I actually use my phone for work calls, emails, plus personal calls and emails as well....and i'm an avid gamer and already have many games on my Vibrant and use it to play them regularly.....then there is the fact that I travel for work....a lot, so I constantly using google voice search and maps to find where i need to go (never use the gps though)....I used the internet all the time, especially on WiFi (higher battery drain)....and don't get me started on the movies, music and youtube....plus while at work I have Pandora running from my phone throughout the day....
So how is my battery life? I unplug my phone every morning at 9am, with all that use I don't need to plug it in again till 10-11pm (12-14hrs!!).....by that time of course the battery level is at 5-15%.....But I'm definitely not complaining....
I do however disable the auto-brightness feature....AND turn down my brightness to about 30%....50% brightness cuts about 2 hours off of the battery life....
But a GREAT PHONE!!! Loving my new Galaxy S Vibrant

yeah, i feel the same way. As far as phone taking forever to charge, are you using the usb-computer charger or usb-wall? The usb-computer can be very weak depending on your system.
Charging from pc, i would wake up only to see 65%. That's pretty crazy. On the wall charger, it takes less about 4-5 hours every time.

Anyone loosing like 6 percent in the first 15 minutes after a full charge? 15 minutes ago i was 100% now im at 94....

I get better battery life than i got on my G1.
These are not cell phones... they are tinny laptops that you can press against your face and make phone calls.
This thing has more features than the $1200 gaming PC i built 2 months ago.

I had bad battery life the first day. Turned the phone off late at night and let it charge full. Battery has been wonderful since then.

Whats the most battery life we've seen?

Alright so, I know people frequently post pictures of their battery life "Unplugged for" screenshots.
So I'm wondering, whats the longest we've seen, with atleast 2 and a half hours of display on-time?
And what ROM/Kernel were they using?
EDIT:
Hit my personal best today, heres a screenshot:

5% Battery remaining according to Battstatt.
Display time is 2 hours 26 minutes
Time without signal is 86% (Horrible service here)
Voice calls is 21m 13s

You didn't post what rom/kernel you are using.
I'm running the stock rom and getting fed up with the terrible battery life...so I'll be monitoring this thread to see what my best options are.

Oh my bad man.
I'm running Baked Snack 1.5 ROM with HeroSpecial#2 kernel right now.
Its still at 5% and currently 2d 19h 14m. Could prolly get 3days to read on there if I felt like it.

I have to say I'm getting amazing battery life with Baked snack 1.5. I had the phone running for one day and 18 hours, I spent about 3 hours on the phone and using it constantly to check messages. I'm very happy with my phone.I'm installing 1.6 now, it should make it to two days. I had WIFi on all day.

2 hours of display on time over 3 days? Anyone could get ridiculous battery life if they never use the phone.
The ONLY way to compare battery life semi equally across various roms/kernels/settings and setups is to restart the phone, turn off the display, leave it for several hours without using it at all, and measure what the %loss per hour is for a completely idle phone with no use. The longer you leave the phone idle, the more accurate the measurement of % loss per hour will be. We can then compare how much power various setups are using in idle as a baseline.
Anything other than that is open to people messing with their phone or turning on airplane mode or never using it and claiming amazing battery life.

First, that was my normal use for those two + days, didn't have time to use my phone other than for texting and such. And if your a texter, than you know it only takes 20seconds TOPS to reply a text message, and texting is a majority of what I did with those two+ hours. so we'll say 1:45min of it was texting.
20seconds of on screen time per text = about 315 text messages, which is about what I did.
To me that is great battery life, if I can get that much battery to do that than I'm happy.
As for the way you stated, I guess this counts:
When I slept, I slept for 8 hours and some odd minutes and lost 3% the first night and slept I believe 6 hours and lost 2% the 2nd.
I guess that would mean 3hours idle = 1% battery drain judging by your method? Idk. Lol.

Ummm I don't even see why you need this phone if all you are going to do is text with it. There are so many other phones that are smaller, lighter and way better on battery if that is all you do. The LG rumor 2 comes to mind.

Meh, I guess since Baked Snacks thread got closed, none of you saw my post in it before it was, stating why I wasn't using my phone much -.-
I was back and forth to the hospital all this week, no time to worry about charging my phone and no time to use it much other than quickly texting. My grandmother is in there but thats a personal note and doesn't relate to any of this.
Anyway, point is, I wasn't able to worry about charging my phone much, and I was impressed that it made it through all that without dying on me, I was planning on not having a phone for a day because I knew I wouldn't be charging it. Thats why I was impressed.
But thanks for the suggestion of yours. I'll be sure to write it on the next piece of toilet paper I use.
And can we please get back to the original reason I posted this thread..?
Nobody has mentioned the best battery life they've seen on the epic.

Well that seems like some good battery life if you only lost 1 percent every 3 hours. Airplane mode? juicedefender?

Whats the normal drainage for idle phones?
Neither, I just turn 3G off and force roam it at home with Roam control because I get 1-bar while roaming and 0 bars with Sprint coverage at home so roaming helps the Time Without Signal a very little bit, on sprint it runs at 99% without signal at my house and on roam it runs at 80-90% without signal.

I get a little under 1% an hour when idle usually. I would have to check it again tonight to see what I am currently getting. I am using phoenix 1.43 and EE 1.2.03. I use juicedefender and disable drm and toggle airplane mode and all that nonsense.

i'm curious what most people are getting for % battery loss with screen on. i feel like mine tends to be high across several ROMs and kernels. its varied somewhat of course, i've used AOSP magic, EE, Syndicate and on baked snack 1.6 now. my numbers show approx 1% battery loss for every 2 minutes of screen on. so that would only be 3hrs 20min of screen on time total which is junk, lol. anyone else got reports?

First, there's just way, way, WAY too much pissing and carping that goes on around here between people about their different usage models.
We each use the phone the way we use it. If you hardly turn it on, you'll get awesome battery life. If you use it like a combination phone/PSP/iPod/Nuvi all day long, you'll get horrible battery life.
I fall in the latter category. I use my phone for business, so I talk hours a day on it. I use it for navigation in the car. I watch probably 2+ hours a day of video on it in the evenings. I listen to music while I'm out and about. I play games when waiting around (like in the doctor's office).
I do all of this usually with wireless bluetooth.
So, I'm happy if I get 6-8 hours out of a full charge, which is rare. However, it's not because the Epic has a crappy battery or sucks juice... It's because I use it to it's full capability throughout the day, every day.
That said, muyoso's point is spot-on when it comes to comparing battery hog/waif in terms of ROMs and kernels. The only thing that matters is non-use. A setup should be very stingy and sip electrons when nothing's happening. Under interactive use, there's little to nothing a dev can do to squeeze more life out of 1500mAh than, well, 1500 mAh.
I've been running Syndicate 1.2 for 24 hours now, and I can say that when the phone is idled, it's far more stingy with power than the stock ROM. The latter drank milliwatts like it was weightlifting when it was asleep and nothing was going on. Syndicate seems to barely be breathing at all when the phone's asleep -- just how you want it to be.

First, there's just way, way, WAY too much pissing and carping that goes on around here between people about their different usage models.
We each use the phone the way we use it. If you hardly turn it on, you'll get awesome battery life. If you use it like a combination phone/PSP/iPod/Nuvi all day long, you'll get horrible battery life.
I fall in the latter category. I use my phone for business, so I talk hours a day on it. I use it for navigation in the car. I watch probably 2+ hours a day of video on it in the evenings. I listen to music while I'm out and about. I play games when waiting around (like in the doctor's office).
I do all of this usually with wireless bluetooth.
So, I'm happy if I get 6-8 hours out of a full charge, which is rare. However, it's not because the Epic has a crappy battery or sucks juice... It's because I use it to it's full capability throughout the day, every day.
That said, muyoso's point is spot-on when it comes to comparing battery hog/waif in terms of ROMs and kernels. The only thing that matters is non-use. A setup should be very stingy and sip electrons when nothing's happening. Under interactive use, there's little to nothing a dev can do to squeeze more life out of 1500mAh than, well, 15 mAh.

Because of how an AMOLED screen works power usage will vary greatly depending on brightness setting. So, taking care to adjust the brightness to suit viewing conditions regularly can make a big difference -- or use auto brightness.
I don't think the latter does a very good job, and I don't like it surprise changing/adjusting while I'm using the phone, so in all my anal retentiveness I constant adjust it manually to suit me.
Thank God for the nice notification-bar-finger-slide-brightness feature that Sammy added.

Hey, if you guys can engineer a fix to the incredibly stupid non-mixing, single-audio-source idiocy of Android's audio subsytem, I'll give you a very generous donation. I love almost everything about my Epic and Android, and haven't looked back wistfully to my WM Omnia II until I noticed this... Can't believe Google botched something as tecnically simple and unchallenging as this.
I mean, really... there's public domain, GPL code out there that could have just been plopped in to make a barely decent sound subsytem. It's a crime that my music mutes every time I get a notification about an email, SMS, etc.
The only solution is to disable sound notifications, which I've done. I can easily live with that, but I shouldn't have to.
One thing the ACS team might consider is adding an option to disable sound notifications when certain apps are running, like media apps playing music or video.

I think for most, if you just root the phone, disable the DRM, and run a program like Setcpu it will make a dramatic difference. It did for me. I just set SetCPU to throttle down when the screen is off.

Battery life

Has anyone seen awesome battery life with this thing or is it just me!? It's been off the charger for 4h20m and the battery is as 87%. wifi off, gps off, bluetooth off, sync ON. just text messaging all day, maybe 20 texts total (slow day today). little bit of facebook, little bit of email, thats about it, so i didn't really do much with the battery but even so with this kind of use my evo would probably be down to around 70%.
battery indicator pro says the display is responsible for 64% of the power drain and cell standby is only 12%, whereas my evo usually had around 50% cell standby and display was only like 8%. was the evo just really bad at holding a signal or what? my display is at middle brightness, if you use the power control widget.
can anyone else tell me how much % their display uses? and what their battery life is like?
after typing this post it's only dropped 1%. word.

Personally, I don't have much of a basis for comparison. I just got my Shift on an upgrade from an aging Samsung feature phone. I've heard all about the horrid battery life on the Evo. My brother has one and can't get a full day of use.
I was out with a real estate agent looking at houses for 6 hours yesterday. We used the GPS a little bit. I was checking NFL playoff scores every hour or so. I was also texting/emailing lightly. 4G was off. By the evening when I put it back on the charger it was still in the green. I didn't look at the power meter specifics... wish I did.
And today I'm just about to leave the office right now. I'm at 8 hrs, 59 min since unplugged with 6/10 green battery bars. (Hey... how do I get the exact percentage? Thanks!)
Display is 62% of my usage (It's set to Auto-brightness). Android system is next at 20%... Light email/texting use all day long at work. Played games for 30 minutes during lunch. Downloaded some new apps (using 4G). Wi-Fi and GPS off all day.
Overall it's a little better than I expected. But I know I haven't really had a heavy day of use yet.

Battery Indicator Pro is a great app that runs in your menubar and displays the percentage for you.
glad we're on the same page with the display, though

I almostmreturned the phone. My cycles were:
1st 8+ hours
2nd 4 hours
3rd 2 hours
Did a factory reset on the phone and it has started to turn around.
4th 9:40 min and at 30% when on the charger
5th 10:46 and still going. Battery is at 30%

I've recharged twice since I got it on Saturday. This seems great, coming from the sprint hero

Exactly. My hero sucked. I used my phone lightly and had it without a charge for over 24 hours. Did some playing around setting it up and then some light texting, emailing, and 4g usage. Then turned off 4g. Amazing.

This isn't your dream phone, it's the one after that. You gotta take it out and play with it more!

I've had to charge it twice a day since the sixth, battery life has been terrible.
I have all the stuff disabled, it just seems to drain even when nothing is running.
I did have an issue with terrible signal on the first day, once I did ##DATA# it fixed it, but my battery life is sucking it up badly.
Sent from my bathroom, with toilet paper.

Just got my wife a shift earlier today and ran it down from the half life that came with the battery in about...6 hours. That was with near constant use, the screen on max, wifi, and sync. Plus GPS on for awhile too. Compared to my epic which with similar use can go...maybe 6 hours from full? It depends. I'll be comparing her battery usage to mine over time and I'll post after she gets some use from a full charge. Under normal usage I can get up to 28 hours from my Epic so people reporting horrible battery life must be doing something wrong or have a defective battery. I fully expect her to get a couple days life out of each of her charges though she'll probably throw it on the charger every night.

anyone have an explanation of why the screen is the largest amount of usage under battery stats? yesterday was an average day for me and the display was something like 50%. on my Evo cell standby was always the highest and the display was down around 8 or 10%
edit: this morning the phone has been unplugged for an hour and a half and cell standby is 50% and the display is 11%... *scratches head*

I just switched to Sprint a couple days ago and got an EVO 4G; I am really unhappy with the battery life and though I got them to give me an extended battery for free it still seems like it's dying very quickly. I am a heavy data user and it's driving me crazy; does anyone have any experience going from the EVO 4G to the Shift and, if so, what are your thoughts, particularly in regards to battery life? Is it worth the loss of size and cameras?

i went from the evo to the shift (30 day swap deal) and i haven't even looked back. the battery life is STELLAR as far as i'm concerned. the evo sucked down power like nobody's business. i'm sure if you got an extended battery for the shift it would last you 2 days at least.

All I gotta say is my extended battery experience is amazing. I get about 36 hours out of my evo. Yea it looks a little fugly now but fck it I can abuse it as much as I want too with battery to spare.

I just got the extended battery and haven't charged it overnight yet, but so fast I am very concerned that it is not living up to expectations. However I won't make any quick judgments until I've seen how it does over a couple days.

My Hero got better battery life.
Sent from my PG06100 using XDA App

Typical use for me is pulling the phone off the charger at 5am, light to moderate use throughout the day (texting, facebook/twitter, apps updating ~2-4 hours, etc) and then putting back on the charger at 9pm.
I upgraded from the Hero. The Hero was rooted and running AOSP w/ modified kernel and collin's battery tweak. Battery life was impressive, but performance was an issue. I could routinely get 30+ hours battery life with the type of use listed above (battery was usually 50% or more when I'd put it back on the charger).
With the Shift, battery life is surprisingly good. For some reason I lose ~10% within the first hour, but after that, it seems to settle down and by the end of the day I'm still at ~30% (with the type of use listed above).
Based on what was possible with the custom ROM's and kernel tweaks for the Hero, I'm excited to see what the community can do with the Shift once we get root.

That first 10% drop seems normal for the new HTC phones. I know the Evo does the same thing. Just the way they're charging the batteries

I found this article helpful in understanding the ~10% dropoff when first off the charger.

At what setting do you all have your screen brightness set? Do you use the auto-brightness option. I find consistently that the overwhelming majority of battery use (according to that screen in the settings) is from the display.

Perfect Phone except for battery

I got my SGSII on Sunday and I am extremely pleased with it. Its like the phone of my dreams in almost every way. It's responsiveness, its camera, its form factor, its screen, everything about it was great. Until I noticed that the battery was being drained kinda fast. I rooted it within a day and tried every ROM available so far but none of them alleviated my battery issue. I've read and tried every solution on these forums but nothing works.
I lose approximately 10 percent of battery every 30 minutes and have gained a maximum battery battery life of 8 and a half hours. Ive Frozen most of sammy's bloatware and have optimized it as much as i can. i disabled fast dormancy everything.... I just dont know what to do.

Did you try restoring original Samsung firmware, factory reset with full wipe, and then doing initial setup prior to getting on wifi?
Try this, don't config any account besides google, don't install any software and certainly don't freeze any apps. Monitor phone for a few hours and then post screenshots of Battery Use app for us to see.

I get about 15+ hrs worth.of battery.
With heavy exchange (push) email and quite a few apps.
My problem is random reboots especially when playing music.

Give it some time. Battery life improves quite a bit after some discharge cycles. Do a factory reset and reinstall as some have mentioned above.
And remember some apps can cause the OS to misbehave.

That's the reason I sold mine. Battery life was unacceptable. Other than that, perfect phone!!! Still looking at this forum hoping for solution to battery problem. Would definitely buy the device back then.

Thanks for the advice first thing in the morning ill flash KE7, which is what my phone came with, and report back with screenshots and after a few hours.

Any smartphone battery need at least a good month before reaching the maximum potential.
Just wait a couple of days and use custom kernel with SetCPU.
My ex-Arc did the same, first day battery droped 7% every hour on idle but after a week battery could last 3 days

if u continue in this topic its very better. 1 topic about battery is more better
http://forum.xda-developers.com/showthread.php?t=1070324

For me, it's simply because i'm battering the phone with internet use, and generally playing around with it constantly all day while at work.
I get a full day, sometimes two now, depending on how I use it.
My old HTC Desire used to need charging twice a day, until I got my SGS 2, now the Desire needs a charge once every 3 or 4 days, due to the fact I am playing with my new toy! lol
I'd say battery life will improve as time goes on and usage of the phone goes from all day, to normal smart phone usage
In all seriousness, the SGS two outlasts my Desire easily, which is good enough for me. I struggle to kill the SGS 2 in a day.

If you are losing 10% per half hour, is that with the screen on? If so, that is fairly normal. I find that 5 hours of screen on time is the most you'd normally get. If its in standby mode (screen off) and you are losing that much per half hour then something is wrong.
Those you of who are getting amazing battery life, would love to see a screenshot with more than 5 hours screen on time - just to see if it is possible. 3 or 4 days means nothing if its in standby 99% of the time

Yep, how you use the phone is huge. Screen brightness and many other factors like installed apps and what they are doing can have a major impact on batt life. IMO battery life is almost impossible to compare except your own in static usage after making changes. Even idle batt life is effected by push email, weather, etc. In my own usage I was getting poor battery life to start with (multiple charges per day) or was I? There I was screwing around with the phone constantly. Loading this, uninstalling that, taking browsers for test drives, trying launchers, flashing roms, seeing how different games played, showing other people the phone, and so on. The excitement wore off and I got to normal usage (for me) which since I unplugged 17 hours ago is 18 texts, 7 calls all of which were short, and assorted stuff like doing a search, a little web browsing following the search and so on. I'm at 61% showing on batt and my largest user was screen with 59% and then OS with 11%. So this is pretty obvious, cant make it through the day hammering the phone but no problems with what I think most people would consider light usage. Where I'm going is that I think some people may not realize how much they are using their phones in their wahoo new phone frenzy.

Quoted for truth! With normal daily usage about 12-14 hours off the charger you'll see 5 hours of display at the most. GSMArena has done some tests and in airplane mode playing a video on loop on 50% brightness can last a bit over 8 hours. Once you add in having to maintain a cell signal, wifi, push email, idling for another couple hours, it reduces your possible screen time in favor for those other activities.
The best ways to conserve battery are to make sure you don't have rogue apps that are keeping your phone awake when it should be sleeping. Check your battery graph and actually CLICK on the graph to expand it to check if your "awake" bars line up with your "screen on" bars. If they don't, something is wrong and you have to find out what's causing it to stay awake. If you've been browsing (white) websites on wifi for 5 hours and complain when the phone says low battery... tough. You're using the display, wifi, maintaining a cell signal, as well as viewing sites that strain the SAMOLED display the most - white backgrounds.
Based on my experience, my battery life is actually quite good. After 4 hours of idling and only about 20m of display on (auto brightness) I'm still at 91%. After a day's use with about 1h of screen time and 14 hours off the charger (about my avg workday usage) I end up around 65-75% which I consider not too bad and can definitely go 2 days on my average usage. Basically minimizing the battery draw when the screen is off is key since when the screen is on, nothing can stop it from draining the battery.

Mine,
From 100% to Full drain (Switch Off). Total usage 1d 19h. At 20% Brightness. On XWKE8. More than 5 or 5½ hours is NOT possible, whatever you do. It's not that I am impressed with it, 5 hours isn't enough, 7-8 hours would be good though

Well i left my phone idle for approx. 5hrs and im dwn to 63% but now im noticing a problem that i havent noticed before... my Android OS is now taking up 38% with which is more than Display which only took 21% and the phone was constantly waking up.

You must have SOMETHING that is eating up the CPU. If you are out of guesses, do a factory reset with data wipe, restore original firmware (if you flashed a custom rom), do another factory reset, configure only gmail, and then monitor the battery usage. It would be losing at most 2% an hour in standby. For me it was 1% every 2 hours (with absolutely nothing running except google) when I tested. I the slowly added my apps making sure I do not install crap and do not configure osmething to always do some **** I do not want.

I don't understand these "battery life sucks" threads.
I have an Unlocked SG2 with stock ROM. It is not rooted, I have not frozen any apps. I have four exchange accounts syncing on push, social networks up and running and widgets on all of my screens. I text and check e-mail frequently throughout the day and I use the camera here and there.
I always get at least 15 hours out of my battery, if not more. For comparison, I was using an iPhone 4 under the same conditions (with the same accounts syncing) minus any widgets or automatic social updates and I was getting roughly the same battery life.
No, this phone won't last you a week with heavy use, but you should easily get a day out of it and I rarely find myself in a situation when I can't charge it overnight. This phone is on par with all of the best battery life smartphones out there, as far as I'm concerned. Those of you getting horrible battery life should probably look into an exchange or maybe an app you recently downloaded. The only time I got really bad battery life was when I ran a live wallpaper that was pegging my CPU.

Before going to sleep do these things,
A- Check if 'Auto Sync' is running, Disable it if it was. Same goes for Background Data, Disable it.
B- Go to Task Manager and see if any Apps are running. Close it if some were.
C- In Task Manager, go to RAM tab, Press Clear Memory, it should close the hidden apps were running. ***DO NOT do this if you have some kind of Scheduler application running, it will NOT work then***
D- Download an app like Auto Task Killer.
E- If possible keep the 'Power Saving Feature' on with your desired settings.
Do these first, if not worked, do a Hard reset. For me, it decreases about 5-6% battery (max) in overnight period of 8-9 hours.
Regards.

I'm not sure what you mean by "battery backup". Are you referring to standby time? Yes, the iphone does better in that department, but that's not typical daily use. Phones are meant to be used, not sit around for days at a time. Iphone can do this because it doesn't truly multitask and no data is syncing. Either you have a faulty device, bad Rom, or your expectations are unrealistic .
