Dell Streak Battery - Streak 5 General

Question I'm across the ponder over here in the states. I am really excited about the streak. Ive been using Android since G1 and one thing with Android is they all suck the battery down. What sort of battery life are you guys seeing?

lasts me the whole day easily

would you say that you have mild, moderate, or alot of usage?

I'd say about 18 hours constant usage, as a nice example I got the low battery warning and still listened to another 2 hours of podcasts.
For example, i unplugged mine 7am this morning, its now 11pm and the battery is on 37% with some good usage today.

I get almost 2 days out of mine, or, 1.5x the life of my G1.

Hi wondercoolguy
Well I've owned my Streak for a little over 3 weeks now and from the first charge battery life has been great as it's has a 1530aMh Li-ion Polymer battery. But not only is it long lasting but mains charging it is pretty fast to although i never run it to dead as that's bad for it and it charges from around 35% to full in about an hour below is the kind of use i put it through.
I have both background Data and Auto-Sync on as well as under My Location Use wireless networks and share with Google both on i only turn on and enable GPS satellites when i actually need it.
I am also ruining real time Push E-Mail which is in use 16hrs a day and WiFi is on 12-14hrs a day and my screen most of the time is on full brightness and i have my Network Mode set to GSM/WCDMA Auto. I listen to Music over Bluetooth for 1 to 2hrs most days and will browse the Web and forums for 1-2hrs per day to. I may also stream a TV show or watch a Video for 1-2 hrs a day to. Now with that type of use most times when i come to charge my Streak after 16hrs i have around 38% or more of battery left. Hope that helps give you some idea of what it's like to own and use one.

Thanks for giving me the over view what your day is like with Streak. I'm currently using a Nexus one and it can drink the battery if it really wants to. It sounds like you use it as much as I use my N1 only I got to stay by a charger mid day.
It sounds like with juice defender app my fourth coming streak should last days. If you don't know what juice defender is download it (free) and see how long your battery lasts. I use another app called battery left and it tells you how much time you have on your battery based on usage history the max it estimates is 9hours and thats before I start using it.

@wondercoolguy
Two things i forgot to mention the first is I'm in areas with good Network cover most of the time so my Streaks isn't constantly switching bands or searching for towers.
The other thing is i am not and don't use a Task Killer at all i can and have had as many as 25 odd Active Applications running and around 35 odd Inactive (cached) Applications and still have more than 100 MB of free Ram as i just let the OS get on with it and handle it.
Free Ram is only an issue if you have none and want or need to open another app otherwise free Ram is just wasted and doing nothing it doesn't make your device faster nor does it extend your battery life.
In my opinion constantly killing apps and connections actually uses more battery not less the only thing i turn on is the GPS when i need it and off when i don't. Other then that i just let the OS do what it's meant to and don't bother thinking about what's running or not as unless i have a problem what's the point. I have read all about Juice defender and all the different Task Killers but just can't see the point maybe if i was having issues i may view it differently but for now i just don't need them.
Marc

I had a nexus 1 and work with a few guys that still have them. During the day we have about the same usage and my dell streak consistently has better battery life than their nexus 1. I then switch over to using it heavily when I get home and even then the battery lifes great.
on medium to lower usage times it will last 2 days easily

@Dogmann
Why do you consider Juice Defener a task killer? All it does it turn off your 3g when your phone is asleep. How could this hurt your battery life when its not connected during sleepy time?
It is july 1st and maybe we will finally get our Streak this month. You guys have talked me into it. I'll get my streak I still may wait till 2.2 drops on it. I don't know if you guys got the Samsung Behold 2 over there but it bombed hard in the states and Samsung is going to leave the phone on 1.6. I'm afraid that it might happen to the Streak here in the states.

@wondercoolguy
I don't consider it a Task Killer which is why i said
"I have read all about Juice defender and all the different Task Killers"
That didn't mean i thought it was a Task Killer and I do understand exactly what it is and the the other part of the app that goes with it as before i got my Streak i was reading about all sorts of problems some where having with their battery life on various devices and looked into this app.
Although obviously not Streaks though as they hadn't been released yet and i got mine as soon as it was available, so whilst i do understand what it does if I'm not having any problems with battery life so don't need it why bother?
Now obviously if i was having an issue with battery life then of course i would of considered using it but as i don't i have no need to use it. I prefer to only install apps that i actually need and want rather then just everything i can as believe in the less is more philosophy when it comes to installing apps.
Seriously i wouldn't worry about the Streak not getting 2.2 as that's just not going to happen the Streak is Dells premium smart phone/tablet and they have many more smart phones and tablets coming later this year.
They seem to have serious intentions about becoming a major player and aren't stupid enough to not support their devices and kill their chances. In fact they have already just released a small update for the Streak which although is hard to see what they have changed could in fact be a way of them checking and preparing for the 2.2 OTA update that is coming to make sure the delivery method works is my guess.
By all means wait it out if you want to but IMO you'll be missing out on using a great device as it is and one that is only going to get even better with 2.2 and what ever comes after that.

@Dogmann
Since I've been with Android day one with the G1 battery life has always been an issue, because I've gone from g1, to mytouch, and finally to my nexus one. Each one of them having battery life issues which were confirmed by all the forums out there trying to figure out how to make it better. So I just assume that my monster phone will have the same issues.
From what you are telling me it does not so and it is on Android 1.6 (or 1.5 can’t remember) either way when it goes to 2.2 the battery life will be even better.
Currently I'm rolling with my Nexus One and I love it so waiting 30 to 45 extra days for my Monster Phone won’t be too bad. Supposed to hit the states this month, I'm sure toward the end. 2.2 is supposed to hit in Sept we'll see

Just received my USA unlocked yesterday and so I played with it for about 8 hours. Took that long for the battery bar to go red. I am not using 3G, don't think I can, I don't know ... don't care. With my Nexus One 3g drained my battery .. bought an extended battery .. same thing .. I won't be surfing the web etc .. I will do mostly business things - facebook, twitter, etc .. I do not feel the need for 3g .. I would have to be in the city to get it anyway ..

24 hours w/a Nexus One

I just finished my 24 hour testing of the Nexus One for my employer and figured I would give my 2 cents worth:
1. On screen keyboard: Great, especially when used in landscape. Portrait has a bit more room side to side than the G1, and it makes it easier, but I wouldn't go so far to say in protrait it is a night and day difference. Landscape truly is, and I had no problem typing long messages in landscape mode, and using portrait for quick stuff. A physical keyboard is still a better option, IMO as a keyboard lover, but the onscreen is executed very, very well.
2. Speed/Android 2.1: I have tested some of the 2.1 ports on my G1, and as nice as they are, they do not give justice at all too what 2.1 is on a Nexus One. Blanket statement, the phone is faster and 2.1 is a great advancement. A more astute observation that I wasn't expecting, websites load much, much, much faster on the Nexus One. I didn't do an actual stop watch test, but a realistic guess says sites load about twice as fast. I am on an EDGE network where I do most of my surfing when not using WiFi... when on WiFi it was more dramatic (I actually loaded 1 site faster on the Nexus One than on my computer)
3. Stability: I tried my absolute best to slow it down and make it unstable. Couldn't do it. At one point in time, I had 23 apps open, the browser had 3 windows, I had youtube running, music, and so forth. Of course, several of the apps had to "reload" the last point I was at, but with this phone "reloading" is pretty much instant. The longest it ever took was one of the web pages had to re-download the content. I found that the phone's cache held my normal use just fine without ever having to reload.
4. Fit/Finish/Style: The phone has a very solid feel too, despite being very light in weight. Fits well in the hand, comfortable being used as a phone, and I got a lot of comments on it when I was out and about testing the "wow" factor (I was asked to go to a busy restaurant/bar and see how many people asked me about it). And, as odd as this might sound, being right handed the back button being on the far left was not a big deal, and I actually liked it's placement a lot since when I used it in landscape mode it was much more comfortable hitting it, and I think this is what they had in mind when they designed in like that.
5. Battery Life: Damn! That is all you need to know, Damn! I tried, really, really hard to push this to the max and see how fast I could run it down. I had WiFi and GPS both going, music playing, and was surfing the web as quick as possible, messing around with google maps taking a look at new and interesting places, and gave up. I used 80% of the battery in those 24 hours, for about an hour I was trying my best to run it down, and for the rest a little above typical usage. Today it only went down 20% from 9AM-5PM. My G1 is usually about 60% gone over that period.
6. Conclusion: I am someone that pretty much demands a physical keyboard for me to even think about buying a phone. I am getting a Nexus One as soon as they become available through the company I work for. My manager is a BB addict, and she said as soon as we get it she is switching as well. That is a huge statement, her daily phone is a BB 9700, she texts and writes most of her emails from her phone, and the Nexus One out performed her BB 9700. She was using the google voice service to write, but she said out of all the texts and emails she wrote using it she didn't have a single typo!
Edit:
On the battery, I might not have been 100% clear in re-reading this review, and want to say some people on this board have had different results and opinions. To add another experience, my manager used the phone for 2 days and didn't have to charge it, but she didn't use it nearly as much as I did. I am also editing that part of my review, so if you read it the first day it was posted it might be a little different for clarity sakes.
As expected, from a god of the Android phones.
Thanks pjcforpres for this write up/review. Il been holding out on the Nexus one mainly because of Keyboard. Im with Tmobile and have the latest 2.1 rom. I was even considering going to Big Red for the Droid but your review seems honest and has answered a few things for me with Keyboard, Battery life and speed. I may give it a go. Thanks much!
Building on your 2nd point... I was amazed at how quickly apps installed from Market... it was practically instantaneous!

I want to point out that I edited the battery review part, and added a note at the end. It didn't read as clearly as the original thought when I wrote it.
I'm a hard keyboard junkie myself, and I have to say that I'm still not as great with the N1's soft keyboard than any hard kb. I don't think they will ever quite pare up.
However, the voice input is really incredible I especially love sitting down in my car, long-pressing "search" so the voice search comes up, and saying "Navigate to burger king." The phone opens Google Maps Navigation, plots the course from my location to the nearest Burger King, and begins turn-by-turn navigation.
Nice review...this bad boy has Awesome speed & eye candy!
Good review but the battery life on the N1, as much as I love this device, is horrendous. It's absolutely terrible. But then again, I actually expected it to be so it's not a big deal. I will get the fattest battery I can when they come out. I use the phone so much that I've actually had to start charging it a third time in one day.
honestly, i'm actually faster with the soft keyboard than i was with a hard board, because i don't have to actually press anything. i've tried on other screenboards too, and this thing is like butter compared to those. a hard keyboard was my sticking point for a long time, but no longer. not after this
You know, I kind of experienced the opposite in terms of battery. My G1 would last all day, with fairly regular usage and by the time I went to bed I was around 70% left battery.
I've had my N1 off the charger since around noon today, and its at 50%. so 24 hours at that rate would completely drain my battery. Overnight also, I left it unplugged, it was at 72% when I wend to bed (around midnight) and 60% when I got up (8:30a), so 8 hours standby consumed 12% battery. My n1 is also currently set to 2G only, as I flip/flop 2g/3g at my house (my g1 did the same here since they put up the new 3g tower).
I left mine off the charger overnight, and had 2% consumption. Not sure what to tell you other than check how often you have your stuff syncing, and what all you have in your background. I don't like task killers much, but I do use them to kill any media apps since even with those chilling in the background waiting for you to come back, they like to drain battery.
So far, on the 3 devices being used in our test group, we have all experienced the same great battery life I reported. Like I already said, my manager made it 2 days on 1 full charge (I think that was officially 44 hours). A couple others in the group experiened the same thing. The data specialist, who is a very heavy user (near constant actually) made it through the work day. That is the first time a smart phone has done that, including BB's.
We all have different ideas of what normal usage is and what heavy use is. Being that I sell cell phones for a living, and gotta fill out fun forms that define those for me, I would like to think my idea is closer to average than some of you guys. Let me put it like this, I guess, for me constant use does not =heavy use. Constant use=Constant use. Heavy use= an average of using the phone 30 minutes out of every hour. Average use=Using the phone less than 15 minutes an hour. As well, we factor in what that usage is, is it data? Is it phone calls? Is it media player?
There are tons of factors that can cause one man to think great battery life and another horrible. I tried my best to write my review and assesment based on my personal experience on a criteria that is based off 4 years of selling cell phones as well the guide sheet made up by 25 people with over 150 years combined experience in the cell phone world.

Actually, I think the battery life is pretty good considering the what the phone does. It's just horrible compared to, for example, a non-smartphone. I'm not sure what people mean by "heavy use" but when I say heavy use, I mean my phone is on and I'm playing with it for five hours straight browsing, using data, video, music, games, apps and a combination of those. I rarely talk on the phone. Messaging, browser, music and apps are where I use my phone most. Basically, I use every feature for hours at a time. I live on my phone (for play and work so it's not as bad as it sounds). So if heavy use for others is 30 minutes out of every hour like you said, my heave use is many hours of constant use. But overall, the N1 is a wonderful device and it would take a lot for me to give it up (N2? LOL).
We/ I would call that constant or near constant use. Yes, heay usage might and is what most would call that, but when evaluating battery life on a more concise basis we would call that constant use for clarity and consitancy in the evaluation process from phone to phone and person to person.
I do agree, as well, that many people seem to compare a smart phone to a dumb phone too easily and readily for what their expectations are concerning battery life. IIRC, I can't see it as I write this, in my original post I said for a phone that does as much as the Nexus One, the battery life is great. And of course you say the same!
In my experiences, the Nexus One is just below a BB for battery usage, way better than WinMo, and an improvement over the G1(my personal phone right now). When you consider that it can do way more than a BB, faster, and better, the battery life becomes IMO better than a BB's. As the data specialist found, he actually had better battery life with the Nexus One than he did with his BB 8900 and 9700.

Yeah, it was so hard for me to give the phone to the next tester, it was like breaking up with my first love! I am actually thinking about ordering an unlocked off Google because I miss it so much already!
Although my N1's battery is clearly better than my G1's, it's still not nearly what some people are reporting. On weekdays, I get up about 7am and take my phone off the charger. On my way to take my daughter to school, and then on my way to work, I stream Pandora the entire way, on 3G (about 60 minutes in traffic). I get to work by about 8:30, and my battery at that point is at about 80-85%. My G1 would be about 65-70% at that same point. By the time I get home (about 3pm), streaming music all the way home (about 40 minutes). Battery life by the time I get home is around 45-50%, possibly less, depending on if I did much texting at work. By the time I go to bed (9 or 10pm) I'm at around 20%.
That's pretty much an average day. Only once have I completely drained the battery where my phone would not turn on, and it hit that point at about 8:30pm that day. This was not possible on my G1. I would have to charge it at work in order to do all of the above, and I'd still be in the 10-20% range by 10pm.
I think the biggest difference isn't the hardware 'or' the software, but mostly the 1400mah battery compared to the 1000mah battery on the G1. Although, the fact that the N1 is so much faster, means I get more things done in less time, which means more time in idle, and more battery saved.
I did just notice something though... I've had my phone unplugged since 8am this morning, it's now 2am, and I'm still at 20%... can't complain
what are you guys' battery use distribution?
according to the battery use showed on the phone, the screen drains most of my batter most oftenly more than 70 percent.

That seems to be the prevailing "peak" usage.

What is everyone's problem w/battery life?

Maybe it's because I just came from a G1 and don't have any widgets other than the weather application and Handcent, but I have been online, texting, and calling all day since 12:30pm CST and I'm still in the "green" on my phone and it's 3:11am CST here.
This is PHENOMENAL
PS.. I am a T-Mobile user so not sure if this issue is related only to AT&T but this phone ROCKS!
Not everyone has a battery life problem, there is a poll about it somewhere... I find it fine.
Not a problem anymore, I got used to recharge three times a day
People with battery problems are in the minority. They just complain over and over in order for their voice to heard so it seems like a lot more people have the problem than is true. If battery runs low get a spare to make sure it lasts all day.
Watch, you can hear some of them coming right now to say the sky is falling, I am wrong, and how most people have battery issues...
Some people expect their phone to run games/video/navigation/sync/whatever 24/7 on battery and hold the charge for at least 24 hours. They don't even bother to check the reasons for fast drain (if they have it), and think the phone battery has a flux capacitor inside it. Then, when their hopes aren't fulfilled, they cry in every possible thread on the internet. That's how a wrong impression is made.
Personally, no complaints. Running undervolted kernel, so I have some help with battery life, but still, for the same usage as my old WinMo phone with a battery 1.5 times the size and screen 1/2 the size, Nexus works longer.
Battery life is fine here....and I have 2 spare batteries that stay charged in my fridge (read the article about Li-Ion batteries if you wanna know why I keep them in my fridge - that and if I've been pushing the phone hard and it's really warm, it creates a built-in heat sink when I swap batteries)
I sometimes find my phone draining fast but then stop and think about it and usually I remember some mad wifi browsing, movie watching or gaming I did earlier in the day. I think people too quickly forget about how they've used the device and cry when it's running down.
I have the overclock/undervoltage kernel and with SetCPU to ramp down to 245 on standby, it seems to last ages if I can keep my grubby hands from playing with it all day
Battery life is great for me. And most people in the latest battery life thread aren't upset with what they get. But I am always interested in improving it. And the latest technique posted here does wonders. I expect to get at least 2 days of battery now. It really helps the idle battery usage. Overnight last night my phone only used 6%.
i only have a weather app running along with my gmail 2 accounts and google talk. i am connected to wifi. my battery does drain and needs to be charged at least 1 time per day because if i dont charge it the phone will be dead in the monring. i am testing the network as people say its helping then going to see if the wifi is killing me. i dont see why it MUST be charged daily when it doesnt have much use besides a few messeges and very little calls.
i dont know about other people complaing just because but it is a problem for me and swaping betteries just to send a few messages is out of the question. with all this technology i still have to carry around an extra battery to use it? i think not. im sure it has something to do with the networks on my end.
Running latest Cyanogen. I use the phone mostly for surfing, email and chat. Not so much to call with and very little sms. I live in an area with no 3G but i run it on Wi-fi all the time.
never tried to discharge it through the whole day but i can image a 20-24 hour lifespan on my Nexus with my use.
Think im gonna do a full discharge today. 8 hours passed since last charge.. 72% left on it as i write.

Some people expect the phone's battery to be a 1000MWatt power station...
Well for what it's worth, it is now 2:36pm CST and I'm stilllllllllllll going! Going to wait until it dies completely and then charge it up fully.
It all depends on what they had previously for a phone. People who went from a dumb phone that lasted for a week on standby and more likely 3 days with regular use will get all sorts of uppity. With smart phones, it turned into getting it charged overnight as the norm, at least it was with the last two WinMo iterations I had before getting the N1. The theory goes that it should be the same with the N1 but consider exactly how much more you actually do with an N1 vs WinMo.
The battery life is comparable with the iphone if not just a bit worse due to the N1's ability to actually multitask. Ask any iphone user and I'll bet there's the ever so spiffy tiny little wall charger handy or readily available.
If you go the route of CM and a UV'd kernel as well as making sure you're not searching constantly for any cell network(ie: get off WCDMA Preferred), then you can realistically get back to that charge only overnight routine.
Everyone's mileage will vary on this one. Adapt to what YOUR standard use is and move on. If that's not good enough, then seek out the services of fleabay and Craigslist to recoup your losses and go back to a dumb phone.

Battery Life?

How has everyone's battery life been with the Vibrant? I'm having a few issues with mine, I barely used my phone today, and its down to 57%, with cell standby taking up 33% of the battery.
Search the threads.seriously there are like 5000 battery life threads

So is there a fix for it? Or is it all samsungs fault? Or will the update solve it? This sucks, my battery can loose 30 percent in a matter of 2 hours...
Your battery has and always will react to the way you use it. If you a new user and play with it all day then its going to go fast. If you use 3g, wifi, bright screen you are going to get crappy battery life.
If you use it like a normal person with 6 to 10 calls a day, light web usage, some text messages you should get a battery to last you all day.
Fire up the screen and watch videos or listen to mp3's all day well then your not.
I turned off every little thing, and i still get crappy battery. Wifi off, gps off, sync off, wallpaper off, the whole shabang.
Does your phone actually die, or does it just show a percentage you are unhappy with?
The measurement seems to be a bit off on the Vibrant.

I was disappointed woth my battery life as well. But I wiped the phone and the battery performs better in my mind. Anyone else have a similar experience?
Sent from my SGH-T959 using XDA App
After discharging/conditioning it a couple times, my battery is much better. 9 hours of standby overnight, it only lost 10% battery. That's pretty good IMO.
I just unplugged my phone an hour ago, watched some videos, browsed the web and my battery is down to 86%. It dropped 14% in less than an hour!

Is this your first smart/android phone? Your battery doesn't sound far off for an high end smart phone.you'll eventually learn how to extend the battery, especially after the newness wears off and your not playing with it 24/7 like most of us right now.remember this is an extremely high end phone, it takes a lot of juice to run the high end chip set.if you buy a high performance sports car do you expect to have some fun with it and get 30+mpg doing so? You've gotta understand what you've got. Soon enough there will be extended batteries available and if your willing to root, many devs are capable if tweaking the os to get the most out of the battery without hampering speed our features.

I'm having major issues too. Down to 28%(down to 25% now just typing this message) after 3 hours this morning. I just powered off and back on and I went from 50% down to 28%
Here we go again g1 all over again Seems like the only way to keep power is to uninstall everything.
I'm also seeing cell standby as a possible issue.
Frustrated... Guess it's time to reset to see if one of my apps is the issue...
I have 35 percent left after being off of the charger for 1 day and 5 hours. This is with light to moderate use, meaning some browsing, some phone calls, some market downloads, about 20 minutes of gaming, syncing, and reading e-mails. Of course my mileage varies if use the phone more. When the phone is about to die I'll snap a pic to share how long a full charge has lasted me.
Already this battery is lasting me 2-3x longer than the G1.
I tried a different battery and it's been really good to me =)

Of course my mileage varies if use the phone more. When the phone is about to die I'll snap a pic to share how long a full charge has lasted me.
Already this battery is lasting me 2-3x longer than the G1.

What percent do you show for "cell standby" from setting->about phone->battery use? I'm starting to think that my poor reception area is my issue.
I think the battery percentage shown in the Status is off compared to what is shown on the battery icon. That said, my battery lasts all day with normal use. If i use the web more than normal, of course the battery goes faster but still i usually get all day out of it. May have to charge it some in the evening.
Was hoping it would be better like the iPhone 4 battery seems to be. It is said that 2.2 will have a bit battery life but we'll see. Believe it when i see it.....if we ever get the update
My wife and I got Vibrants at the same time. She was getting great battery life, around 70% by the end of they day, and I was dying just after 1pm. I assumed that i had a defective phone, but decided to wipe it and try running "stock" prior to returning it for a new one.
After wiping the phone and starting over, I'm getting much better battery life, but I think that it's because I didn't use "push" email. I have a corporate Exchange email/calendar/contacts account, and before I had it set to 'push" (or something like that, my phone is syncing DoubleTwist right now, so I can't check. ) When I re-setup my email account, I told it to check only every 15 minutes.
My battery life has been much better this time around, and I think the email sync setting is 1/2 the reason, the other half being that T-Mobile coverage isn't great where I've been the last week. I'm guessing that the "push" sync meant that the phone needs to keep a data link to the server, which is fine if you have strong coverage. When it's weak, then the radio has to work overtime trying to maintain a link, which drains the battery.
I'm going to try this out today and tomorrow, and if the battery life is better than I'll keep it rather than try trading for a new one.
For one, if you're having a battery issue, buy a charger or spare battery. Get a task manager to kill your apps after a certain time and check into what services are running in the background. Just cause you're not playing with the phone doesn't mean its not running or using the battery.

Cell Standby is at 24 percent.
Maybe its some quality control issue in the batteries? Everyone is getting such varied battery performance. I'm thinking of calling T-Mobile and requesting a new battery.
I notice on reboots many apps get started automatically. I've gotten better battery life just by manually shutting them down with astro file manager app. Ultimately any time an app is running even if its not using cpu cycles it still costs power to keep it in ram. Manually shutting down will minimize this obviously.

Battery life is getting better and better.

I haven't really done anything different, but my battery life in the past few weeks has just gotten better and better.
Right now it's 3pm. I put in a fresh battery at 9pm last night. Batt level: 55%. I was asleep for 7 out of those 18 hours, but I've had wifi and BT on the whole time. I've read and replied to 15 emails, maybe 10 texts, 15 min of calls, surfed the web for 2 hours, played about 30min of games, and had music streaming for 1.5 hrs. I've easily been making it through long work days (8am-8pm) of moderate/heavy use, whereas before I would need to recharge after 6-8 hours.
Anyone else noticing better battery life after the first few weeks? (of course, it might have to do with the fact that I'm playing with it less, but there are days when I play with it constantly and it's still doing better than 12+ hours)
I'm still on the first week with my current vibrant and I have noticed a slight improvement in battery life since I first got it--the fact that my life is pretty consistent day to day (phone-wise) helps me track it. Maybe the hardware and software need to be 'broken in' per-se?

Yeah, it does get better, but 12 hours is not good enough nowadays -- if you go to dinner after work, the battery will be dead before you get home.
This is my biggest gripe about the Galaxy S -- compared to my old iPhone 3Gs the battery life just sucks.
I am hoping that the efficiencies that come with Froyo will squeeze a few more hours and make it usable for a full day.
If Samsung gets off its lazy (or incompetent) butt and upgrades us to Froyo soon, of course.

The question is, what are you not doing? We can all get it to last the long, but this is a smart phone. I cannot afford to treat it like if I was stranded on an island.
Before I get into my post I just wanted to say I'm running stock out of the box with no root/ROM/etc. Just plain ol vanilla Eclair...with the JI5 via Kies.
I'm getting about 32 hours myself. I do use tasker to set up profiles only to turn things on when I want them. Such as sync will only be enabled for specific apps when I run them then off when I close them. GPS is only on when I run Maps/Yelp/any geo-aware app then it turns itself off. Turn on silent mode/vibrate when I'm at the office by recognizing specific cell towers...stuff like that.
I also disabled "Use Wireless Networks" under Location & Security since Google says it will use it even when the phone is off. I don't know why but it's been saving on battery too. I also don't use any task killing app such as ATK since I think the phone should be smart enough to manage the memory by itself.
edit: Oh, I use automatic brightness settings too with manual brightness control on the browser (usually on low-med setting)

Everything enabled except brightness. i turn off wifi and bluetooth when sleeping, and have sync set to once an hour for social contacts and such. For facebook etc i manually update my feed when i want to check on it, or it auto updates every hour.

I'm at a point of consistent battery life of about 13 hours of moderate to heavy use. Been this way since about the middle of August. The longest I've pushed it was close to 21 hours but i'm normally in the 11-12 range.
Glad your phone is leveling out though

Nah it's not any different from when you first bought it, you're just using it less, even though you think you are using it the same.
Trust me, when people buy a new phone, the first few days or couple weeks they can't take their fingers off the phone, and it appears battery sucks. As you get over your new toy phase, you don't play with it as much, and magically you think the battery has grown new cells.
bye.

There are easy ways to take care of this if you really need better battery life. First, call T-Mobile and complain that battery life is shorter than advertised. They'll walk you through a script and send you a free spare battery. Second, get an external battery charger. They're all over ebay for about ten dollars, and most come with generic spare batteries.
I've now got a charger and three batteries, so I can pretty much make it through an entire work week without worrying. (You couldn't do that with a 3GS!)

You really like carrying a pocketful of spare batteries?
I have 2 spare batteries, but I pack them only when I travel.
The damned phone should be able to last throughout a full day (meaning 16 or so hours) without having to worry about turning features off or limiting your calls and mail checking).
I never had to even think about the battery with my iPhone 3Gs.

I get nice battery life but I use it too much, then "a day" is from 5am to 10pm, it's just too useful, and when you check usage, it's 75% display.
36 hours would be easy if I limited my screen on-time....while I would like a UV kernel it's likely not helping enough. My display is on lowest, yet I'd love a lower setting.
Aside, the more background services check stuff while screen is off, battery life hours down.
Overall, I am VERY happy with the battery life.

Um, the batteries are pretty small and skinny. Are you wearing pants with no pockets or something? Seriously, the thing can almost fit in the coin pocket of some jeans.

Should? Says who? The phone is pretty average for its class. You can either complain that things are not the way you want them, or you can adapt by carrying around a diminutive spare battery.

You must be one of the few 3G/3GS users to never worry about battery life. Most of the users I know have (or had) to recharge mid-day, a pain in the butt since the battery is not removable. Your 3GS has a much slower processor/GPU, and a smaller screen with a quarter of the pixels; but even then, google "iphone 3gs battery life" and you'll get page after page of reviewers and users complaining about the abysmal battery life.
(of course, someone here claims that his Vibrant can go 40+ hours, so maybe your iPhone is a similar outlier.)

Its exactly what the problem is. When I flash a new rom I spend 30minutes getting back to the way I like it and my battery suffers from it. When I actually use my phone like its intended to be used I get great battery life.
Are you using any kind of ROMs? I think some ROMs greatly improves battery life.

Dude, I've had one iPhone 2G and two iPhone 3Gs. I also have two Galaxy S variants (international and a Vibrant).
There is no comparison between the iPhone 3Gs and the Galaxy S in terms of battery life. With the same kind of usage, the iPhone 3 Gs would last about 32-37 hours, while the Galaxy S would last about 12-13.
Even the iPhone 2G lasted about 18-20 hours. Now, compared to my previous HTC WM6 and WM6.5 phone, the Galaxy S does have longer battery life, but that's nothing to be so proud of.
The Galaxy's screen is certainly better than the 3Gs's, but the Super AMOLED is supposed to be more efficient than the LCD on the iPhone. Plus, in real world use, the iPhone 3Gs certainly feels smoother than the Galaxy S, even with the lag fix, and scrolling on the iPhone is smooth as butter, while the Galaxy S is choppy.
And it's not just the OS, because the EVO scrolls noticeably smoother than the Galaxy S.
I consistently get 20+ hours out of one charge. I can't really use my phone at work, but during breaks and lunch I'm always getting on it and checking mail/feeds/youtube or whatever and still have about 70% by the time I go home. I usually have more than half by the time I go to bed unless I've been doing some tethering or heavy audio/video streaming.

why is battery drain so different

hi
this is not question, just more a thought
now i have read on several post on different forum, about the battery drain on the galaxy s 2.
and my big "concern" is why is there sooooo big different on the battery drain. some people can last for 2-3 days and some only 5-8-10 hours. from what they are telling they are using the phone almost equally..
for an example this first post here, he still have 50 % left, although he saw video,playing , surfing and call http://forum.xda-developers.com/showthread.php?t=1055164
mine last for about 10-12 hour with moderate use.. and i have killed all unused apps/task/services, wifi ,only 3g, low brightness, wipe batt state.. and installed villainrom
it sounds to me that some people get a really good phone/battery and some not.
Everyone's idea of light, moderate and heavy use varies. It really only comes down to a few major things. How long the screen is on, how often the device is awake, and how intensively the device was operating while awake.
If people know what to do (search the bloody forums for a start)they can achieve good battery life, too many fools are too quick to come on here and complain about poor battery life without even searching the forum, also anyone who gets 2-3 days clearly isn't using the phone that much, i usually get a full day out of medium/heavy usage and you cant complain about that, this is a smartphone and if people are that obsessed with battery life i suggest they use an old Nokia

Very true. I can easily get 2-3 days if I just used it for calls and text.
Heck, I can get it to last 1-2 weeks. Just put it in flight mode and don't touch it except every couple of days to check %.
Why people don't just buy spare batteries is beyond me. I bought 3 spares + a wall charger off eBay for around $10. When I'm low I just pop the used one in the charger and replace with a full one. From 0% to 100% in 30 seconds. I even leave one in the car in case. Did the same thing with the S1.
BTW, to the OP why leave it on 3G? I'm assuming you switched off H. For me I use the 2g-3g widget and select GSM only. When I need 3g/H for data I turn it on.

My 2 cents
I will tell you this. For what its worth.
I've had 4 friends get the GS2. 2 of them are white, 2 are black (the phones, not them.)
In all four cases with the stock ROM They came and complained to me how they love the phone but the battery dies before they can get home.
All four cases I've done this update for them via ODIN
- ROM Update: XWKI4 (UK XEU, android 2.3.4 to support google video chat)
- Kernel: XWKJ3 (stock)
- Modem update: XXKG5
Each and everyone has told me they're getting literally exponentially better battery life, snappier response and stable usage.
Take it for what its worth. But i recommend your combo.
I think usage pattern is definitely important but i've experienced idle drain and gone through months of struggling with this. not all roms/kernels have the idle drain issue. The above combo should work well for you. Good luck

Well there are differences in software and usage, but thats it. use a clean up to date rom, good kernel and do not install crappy apps like facebook which drain the battery. Using a modem which suits your provider does make quiete a noticeable difference, especially with hspa activated, idle aswell as using the data connection. Battery life of 12 hours or less is clearly a use or apprelated problem.
