I wanted to test out "mapmyride" and use its gps recording feature. I fully charged my battery and as I took it off the charger I started the recording feature.
After I reached my destination I looked at the battery stats.
It said mapmyride used 17% of my battery, and it was in use for exactly 17 minutes.
Ouch.
That means if I ever want to record my route the farthest I could go for is 100 minutes.
Not if you use a car charger.
Then again if you are on a bike it would make things a bit difficult. LOL
Maybe it's not the gps, but the applucation that consumes the battery? Try using a different app, such ad google tracks and see if it performs better or worse.
Gps does use a lot of battery but I'm not sure 1% a minute is normal.

Same thing happened to me on my second Vibrant (used GPS for ~50 mins and lost ~50% battery). I haven't been able to properly test GPS on my current (third) Vibrant cause it loses signal so often.
P.S. I used Google Maps
Sounds about right... gps munches, I say again munches battery .....

My friend used his iphone to track his ride for 3 hours and drained only 10%. I can't even get 1.5 hours on a full charge.
Really??
Maybe we should let google/samsung know about this. the GPS on my phone drains battery too!!
doesn't gps eat battery on all phones??
Might be time for a portable charger

Either that or you might want to check your settings in that app and see if you can maximize the use of the GPS.

It drains it on PNA's too.
Has no one ever used a standalone GPS unplugged? Those things can't last more than an hour. Why? Because they're constantly pulling data off of GPS satellites - and they don't even have to worry about UMTS, GSM, and wifi connections like your cell phone does.
Folks, there's a reason that PNA's are constantly plugged into your car's power, and that reason extends to phones. Not exactly sure why people get surprised by this.
As for the comparison to the iPhone, i'm going to go out on a limb here and say that the reason the iPhone drained less is because the 3rd party app programmer decided to poll the GPS satellites less frequently, or used some other form of location detection (wireless) triangulation along with trajectory estimation to relatively accurately depict your route. That method would use up a LOT less battery, and has nothing to do with iPhone vs Android, and has everything to do with efficient programming.
Is the drain on your GPS high? Yes. Is it normal compared to every other GPS device when the GPS is in constant use? Yes.
From what you described it didn't use 17% of your total battery, it used 17% of the total battery power that was used from the last time you unplugged until you looked. I'm sure your screen, the OS, and other services used some of the total power too.
For example, let's say you started with 100% battery, and when you were done with your ride it was at 90% full. So a total of 10% of your battery was consumed during your ride.
When you look at that battery usage screen, it shows the percentage that each app used of that 10% total battery that was consumed. This includes everything that used your battery.
Of that 10% total, your ride app used 17% of that 10%, or 1.7%
Using my made up numbers, your app actually only used 1.7% of your entire battery during that time.

Yup, this is correct. I realized this after I posted. It seems my situation was extremely coincidental. Total battery life drained was 17%, I used the app for 17 minutes and the app used 17% of the 17% total that was drained. So in any case, a combination of the app and something else did actually drain my total battery life for 17% however.
I used the google tracks app today. I had a 100% charge pulled it off the charger got a gps lock then hit record shut off the screen and threw it in my jersey pocket. I did 22 miles just over an hour it drained only 20%. I had the poll gps @ 5 seconds.
This battery usage is about the same as my nokia n900 gets.
My blackberry 8900 did 10 hours of gps then died.
People if you try to hit the satellite every .5 or 1 second it will kill any battery, change it to 5 sec or 10 sec and you will have no more battery problems. Google Tracks can change this i dont know if map my ride can.
one thing i noticed about the BAD gps on this thing is that when i was moving it wasn't that terrible, had me on or very close to the road in maps. About the same as my nokia would have. But when i stopped holy omg not accurate at all, it was literally all over the place.

The most I could do with the iphone 3g was about 2 hours, so apple must have made some pretty big changes for that sort of run time.
Sent from my SGH-T959 using XDA App
I ran a second test today for the same time / distance making sure everything else was off. 18 minutes of GPS use drained a total of 10% of my battery. Better then the first run, but still lacking for the ability to actually use this in the real world. Right now it would work at best for 3 hours max. I wish this app had a polling rate setting.

I am still not too happy with the battery of the Galaxy, even though it should be conditioned by now. Nowhere near as good as the iPhone 3Gs, even though the 45nm chip in the galaxy, as well as the AMOLED screen, should be benefitial to battery life.
Maybe a good benchmark would be to see what readings people get at the time of the first "Low Battery" warning. You can see what depleted your battery by going to Settings/About/Phone/Battery Use. To get details, touch the corresponding bar in the graph.
Mine are:
20h 32m 4s since unplugged
Display: 38% (1h 54m)
Cell standby: 24%
Phone idle" 16%
Android OS 10% (CPU usage 50m 4s)
Voice calls: 6% (2m 54s --- WTF?!)
Android System: 4%
K-9 Mail: 2%
Advanced Task Killer: 2%
Those numbers look good to me somehow, I wouldn't expect better battery life after using the display for 2 hours and another 19 hours of standby? Especially as the phone can easily stand by another few hours on the last 15%...
i just got my phone recently, i'll post my results after a few weeks of daily usage.
i do a lot of 3G+, WiFi and SMS, not so much voice call, but regularly enough like two or 3 calls a day
that should be a pretty good test to see how long the battery last from full to like 20% that's when i usually recharge my phone if i don't carry a spare battery with me

It depends on what you compare it to, I guess.
I am comparing it to my old iPhone 3Gs, which would last about 48 hours, usually with considerably longer talk time than the 2m 54s I have on the Galaxy S. How can less than 3 minutes of talk show 6% battery drain?!
As I noted, the Galaxy S's smaller die (45nm) and AMOLED screen should be an advantage over the iPhone 3Gs's older hardware, yet the iPhone lasts markedly longer.
Anyway, I just wanted to see what others are seeing and how long their phones are lasting. It might be interesting to many others, too.
The galaxy S holds considerably longer than the iPhone 3GS. Probably longer than the iPhone 4 as well.
My current stats:
2D 0H 33M 41S Since unplugged
Voice calls: 34% (38m 37s)
Cell Standby: 28%
Phone idle: 19%
Display: 18%
Funny, it doesn't show the time when i played SandStorm and Asphalt.
Oh, and my current battery level: 66%
If i skimp on the battery, i can hold 5 days between charges.

WOW! This is just amazing!
How long was your screen on for only 18%? (I have mine set at the dimmest, but still....)
Do you use email much and if so, how many accounts and often do you have the phone checking it?
Wait, you use tons of WiFi and you're suprised that the phone won't hold too much?
In contrast to the iphones that require you to manually search for a network, android ACTIVELY searches for local open networks and connects to them.
When you're not using WiFi- TURN IT OFF.
If you're talking about cellular internet, that's another thing.
And the display (set to medium-low brightness, the brightest mode where it doesn't BURN MY EYES. Damn this display is bright) registers 1h 27m.

For what it's worth, my WiFi has been off for most of the day.
But, on WiFi discovey, my experience has been the opposite.
On the iPhone 3Gs, I always had WiFi and BT turned on. if I was not connected to WiFi, but WiFi became available, the iPhone would bring up a pop up, asking me if I want to connect to the network.
With te Galaxy S, I can have WiFi Notifications on, but unless I search for a network (usually by turning WiFi off, then back on), it doesn't inform me of available networks.
To boot, even though it remembers both my home and office networks, half the time it does not sign in automatically when I enter the area, but I have to do the off/on thing to get signed on

Well consider yourself lucky! you got an amazing battery from the future or something, because this is not what we are all seeing... I get a decent 30 hours with mine max...
Can you tell us how long is the display time ?
My guess is that I could stay 2 days with my phone if I was never swithcing on the screen.
The thing is that you seems to use your phone like I was using my old nokia 6310 ...
Try to play some music or video and you won't last 5 days or even 2days ... maybe 1 if you are lucky
Basically you have left your phone switch off 2 days and call 38mn and that's all ?? I can't tell you that my old iphone3GS is going to be pretty close in term of performance of battery
given that 1h54 give 38% of 85% for the OP I would say that you have maybe 20mn of display
The battery life of my SGS was terrible for the first few days of use. I don't have the battery usage numbers but the battery would only last for around 20 hours doing: 30-60 min call, 2hour music, 30mins video, 30mins game, and approx. 40mins web surf using mostly wifi.
But after about 5 charging cycles (discharging until battery ran low and the phone eventually turns off, then charging the phone to full), the phone lasts for two whole days with the same usage described above each day!
So I have noticed a significant improvement in battery.
If you haven't gone through the charging cycle and your phone is relatively new, give it a week before you think the battery life is crap
yeah I am still waiting for the improvment
After almost 2 weeks , a dozain of cycle I still don't see it coming ...
I guess I must be using the screen too much ( miminum light) ...
Afert 12h46 I am at 25% with 65% taken by the display , 10% by cell idle, 8% by android , 6% by network idle, 4% by call ...
I have already used the screen 3h14mn
I don't know what you do but on my side I am reading my mails, reading xda, reading some newspaper on the train, watching some video ...
So my crappy battery doens't seem to come from some app draining it ... but just from the display.
So basically nothing I could do except using it less than what I am used to
Display time was 1h 27m
mine last around 10h (display on 4,5h) and thats as low as u can adjust brightness in settings according to gsmarena blog display can last up to 10h...
im using dimmer app now. hope i get 5-6h (display time) with that.
ok i'll play:
10hr:10min since last unplugged.
Battery at 74%
Display: 50% (I leave it on auto brightness)
Cell Standby:19%
Phone Idle: 12%
Bluetooth: 8%
NDrive: 7%
Android System: 2%
I'm happy with that.
I'm easily getting through a 15 hour day with moderate use (my normal usage pattern). this is on a par with my previous Nexus One and iPhone 3G.
BTW, I keep the WiFi on persistently (even when the screen is off) because I heard it draws less juice than the 3G/phone data. (I typically spend a lot of time around the house on WiFi ...)
Battery killer is normally "time without signal", the N1 would average maybe 70% without a signal, the SGS is averaging around 30% without a signal - so based on that perhaps the battery isn't quite as robust as the N1 (which was on Froyo).
Anyway, I have no concerns about my SGS battery based on similar phones and usage patterns. I will be tempted to get an extended battery for it though (I had a Mugen 3200mAh on the N1 and that would give me 2 days under quite heavy usage).

Keeping the WiFi policy to never disconnect apparently uses less battery than the system thrashing between 3G and non-3G data when sync'ing etc. Typically WiFi will show as 2% battery usage at the end of the cycle.
I base it off my old N1 usage, which I got from here:
http://www.google.com/support/forum/p/android/thread?tid=006a844d7d335a90&hl=en
ok so my phone has been off the charger for ;
5h 23m 17s
I am at 56% battery.
What concerns me is that my display usage is at 56% of my battery usage with just 22m 27s of usage.
now if I do the math that means the display has used 25.76% of a full charge in just over 20 mins of use.
This seems absurd especially for what is supposedly a more efficient display. Do these numbers seem on par or do I have a faulty battery/device?
Has it been conditioned? I know conditioning does nothing to the battery itself, but it does cause the percentages to reflect more accurately.
Also, was it fully charged 5 hours ago when you took it off the charger? If not these numbers are meaningless.
I suggest comparing multiple charge cycles, not one strange instance.

No, I have not conditioned, the phone.
Yes it is coming off of a full charge.
This is the first day I have taken it off the charger for the full day. I have had it connected to computers via USB to install music apps and get it rooted since I got it so I do not have any other cycles to compare it to accurately.
To be honest these batts do not need conditioning, they have no memory effect.
OP Display is nearly always the most. Unless you make long calls (which could make calls the highest) or never use the phone (stand by would be the highest)...
I would be far more concerned if an app or other device function was at the top of the list other than display.
I had initial concerns about the battery when I got this phone. Now that I have settled into a normal usage pattern (few videos, email, web surfing, Facebook, etc.) I get a full day (7am-10pm) out of a charge.
Just use it as you normally would and don't worry too much about the numbers. See how long it lasts and then adjust as needed. You can disable something that you don't need at that particular moment and make a big difference (like turning off Auto-Sync when you don't need to be constantly updated of your friends Facebook status or turning off 3G when you aren't going to be surfing).

The fact that the display was on top is not what is concerning me it is the percentage of the full charge it used that has me worried.
In the total time off the charger at the time of these stats I used 46% of the battery. 56% of the 46% was for the display. That means that in 22 mins my display ate 25% of my full battery, which would equal out to my phone being dead with 1h 20m of screen time assuming no other resource used the battery.
I have been on here a couple of times complaining about my lousy battery. Well, today I decided to see exactly how far I can take this thing before it conks out on me. Here are my results.
The phone up-time was just over 19 hours, with 14% battery left. (I took my results at 14% because I didn't want the phone turning off on me thus losing all data.) About 49% of the battery was used by the screen, which was on for a total of 3 hours and 20 minutes during this 19 hour period. The rest was split up among other activities, but the most notable/concerning area is 43 seconds of voice took up almost 2% of total battery usage.
I could probably pull out another half-hour or so usage before the phone's battery totally dies, so my final number is 4 hours of usage out of a full charge. This is total usage, i.e. the screen was on for 4 hours.
The phone was at lowest brightness all day except for 10-15 minutes where I had it on full 'cause I was using it outside. I am not using any CPU throttling apps, or such. Background is not fully black. I use one widget, rest are icons. I have Advanced Task Killer which I routinely use to kill tasks, but to be completely honest, unless there is a rouge task ATK does not increase battery life by much. Phone was on 3G primarily, although there were times during the day when I was on EDGE because of weak signal.
All in all, the battery on the Vibrant is pathetic for what it has (Super AMOLED, 45 nm, etc.) but I am glad I can at least last a day. Hopefully Samsung has addressed battery issues in Froyo.
Feel free to post your results on how long you can make your battery last below, so we can all get a better idea. Please do not post "my battery lasts XX days" - give details on your usage, like how I mentioned the battery was at 14% after 19 hours up-time, but actual usage was 3 hours and 20 minutes. Often times it seems like many people brag about how "great" their Vibrant's battery is, but really they rarely use the phone all day hence the "great" battery life.
I completely feel your pain. I had the same issues with my vibrant also. I personally do not believe it is the battery any more because after I applied the ryanza one click lag fix my battery life practically tripled. I kept a very close eye on my usage and settings for the first few weeks. I would get about 12 hours out of a full charge and I would barely use the phone. Frustrated me to no end because I would hear people say that 12 hours with a powerful phone like vibrant is expected. To me it was not acceptable.
I never changed any settings or installed any programs after doing the lag fix but it certainly had a drastic effect. Ill get more statistics when I get home, im at work right now.

Have to agree with this. I tried it out and got quite a boost. I didn't keep as good of details as the OP on my battery use but prior to juice defender a was struggling to make a day. Now a day is not a problem. My typical usage is probably pretty high, lots of internet, lots of tinkering right now plus working on morphs and things, I do keep my screen all the way down except when outside (rarely use my phone outdoors so not much of that), no widgets, no task killer. When I installed juice defender I used the stock settings with the exception of allowing gmail and chat to sync anytime. Juice defender says I'm getting an average of 1.7x the battery life. I think almost all of that comes from when the phone is asleep.
Edit. Checked on details.
Pulled my phone off the charger at 6 am it was at 100%. Used to to do some reading on my way to work (about 30min on the train) worked on some morphs, checked some emails, downloaded some stuff. I'm at 82% and it's 12:20.
Cell standby 39%
Display 33%
phone idle 23%
Various 5%
I use my phone for quite a bit during the day and pull about 13 hours before it starts blinking at me. I personally have zero problems with that amount of battery life from a device of such caliber. My best friend was complaining about her battery in her Vibrant and like I tell everyone else, it's probably some rogue app somewhere. She didn't believe me so we swapped batteries 3 days ago and I still get the same usage times out of her battery as I did mine and her battery life has improved significantly as well.
I don't know what is is that people are doing to get 4-5 hours but 13+ with average use (text, moderate browsing, syncing all day, screen at full brightness all day) is to be expected with this phone. I will post a screenshot of consistency over the course of this weekend to visualize my point.
Also I do not use a task killer of any kind except the Android built in one and I removed hers as well

You mean if you actually use the phone it will drain a lot faster. Your post is a perfect example of what I mean when I said people post very misleading results. For those ~40 hours that your Vibrant has been up, your display has only been on 1, maybe 2 hours (hence only 8% battery usage). Your result is not accurate at all - you aren't using the phone. Anyone can get great battery by letting it sits for hours on in.

Thanks I will look at Juice Defender, but I am not too sure what it will do to help improve my battery which I am not doing already. (I leave GPS off, WiFi off when im not using, have applied lagfix, etc.)
The Droid X is known to get 7-8 hours; and considering the Vibrant has power-friendly hardware, the Vibrant should be getting the same.

When you say 13+ hours, do you mean total up-time or total usage time? Because, as I mentioned in my post, my total up-time was ~19 hours, but usage was actually ~4.

Thanks for clearing that up! Well, it sounds like you are fairing better than me, but without actual data it is hard to say.
Oh, and an FYI: I just called up T-Mobile and had them send me a new battery. FWIW, I am not being charged anything (not even shipping) and I don't have to send back my current battery. I love the retention department .
Can someone post up what they do/what settings they use for juice defender? I installed it but I really don't see how it could save me any more battery seeing that I keep wifi, gps, and all that off, plus my screen is on the lowest setting at all times
Hi all,
What I found out that works best for me is, no task killer, no juice defender, lowest display setting possible, and turning off 3g. 3g ready drains the battery. Task killers are pretty worthless. Do some research on that topic. Android kills programs all by itself. And task killers run in the background, using up battery. My phone is rooted, so I run autostarts to control what starts at boot. My uptime isn't great, but its adequate enough to last from morning to night. I do agee that the battery life when using the phone itself for voice calls is sub part at best. I do believe froyo will help with a lot of these problems. Just my 2ยข.
Sent from my SGH-T959 using XDA App
DON'T use task killer. Vibrant has really good system resource management. With task killers constantly killing core system processes, the phone has to use more power to keep restarting them.
You can read more about it here: http://geekfor.me/faq/you-shouldnt-be-using-a-task-killer-with-android/
And only turn on active sync for apps that you absolutely need to have them syncing all the time.
This should make your phone last for a whole day with decent usage. If you are still getting very short up time, you probably have a bad battery. Call T-Mo and ask for a replacement.
It all depends on usage. The first days when I got my Vibrant, I was downloading apps all day, or browsing websites, so the battery barely lasts for a day. I usually leave my phone plugged in to my laptop when going to sleep, and set the laptop to auto-shutdown in 4 hour, so the phone gets unplugged at about 4:30 am. With that heavy usage, I needed to recharge at about 7 pm.
However, now that I'm not playing with it that much, the battery life improves greatly. Now I usually do 10-20 text messages and about 30 minutes voice call everyday, also some browsing on the xda forum, and maybe reply several emails. The battery is usually at 40 percent at 10 pm. The only thing I can complain about is that with 40% battery left, I don't want to do a complete recharge, but it won't last the second day either.

Thanks for clearing that up! Well, it sounds like you are fairing better than me, but without actual data it is hard to say.

I forgot to take pics lol. (busy with my fantasy draft). I will take some today. Rebooting my phone right before I leave for work and some throughout the day.
It still will be hard to say why my battery life exceeds yours but you will at least be able to compare the two.

I get around 5 hours display. Using wifi sporadically, juice defender paid version, lowest brightness. Our screen is too bright. Lol on lowest it looks like the evo's middle.

Is anyone else having issues with battery life? My wife reported that she was at 70% when she went to take a nap and when she woke up (around an hour later) it was at 30%. I don't have it with me so I can't look up battery stats but I know wifi was off. Even if GPS was still on, you'd think that 40% of a giant battery wouldn't go by in an hour.
I just want to see if its worth investigating as faulty hardware or if there is a software issue involved. She did have meebo running which is a battery drain but even on my captivate with trillian running I don't lose battery like that!
Mine has been absolutely disappointing to say the least. Seems to last less time than my N1.
MILES worse than my iPhone 4.
Is meebo a instant messaging app? A lot of them aren't coded very well and constantly use data therefore killing the battery terribly. I've had my phone on wifi all day since 8am and i'm still at 70%
2.2 isnt designed to take advantage of 2 cores. Therefore its probably horribly optimized. 2.3 if it gets around soon - should be far better.
My battery life is great here.... no complains havent charge my phone since last night at 6pm... i still have 40% left

so far my battery lasts about 20 hours.
I turn off blue-tooth
turn off GPS, wireless is only on when I am near wireless spots
Normal day yesturday:
60 minutes playing WSOP game
40 minutes cell calls
40 texts messages
30 emails
40 minutes playing with settings exploring the phone...
look at whats sucking up your battering in the battery manager, then take adequate measures to fix the battery hogs. My battery gives me more than a full day of play and talk
mine's been off a charger for about 8.5 hours, and it's down to 20%. But it has been streaming pandora continuously for about 6 of those hours, so i'd say i'm doing pretty good. Mix in an odd phone call, playing, downloading apps, setting stuff back up, etc, and i'm not at all unhappy with battery so far.

Stop spreading misinformation.
The kernel (which handles all low-level I/O on the device) is compiled for multiple cores (hence the SMP tag, which stands for symmetrical multiprocessing, under About Phone, under Kernel Version).
On top of that, the Android SDK supports threads, which is in turn supported by the kernel and therefore spread across cores.
I'm suspicious that Motorola is using a bugged battery level scheme or calibration. I ran the battery down from 100% to 5% yesterday. When I got the 5% alert, it was still going strong afterwards for 30 minutes of continual use (downloading apps over wifi and configuring them, browsing the web, etc) after. I eventually got too tired to keep going and see how much longer it'd last.
Does the atrix have better battery life then a captivate?
Of the charger at 7am, its now 2:42pm and im at 80%. I use the phone heavily but auto sync is off.

meebo is awful, awful, awful at battery drain. Utterly awful. It uses a fairly inefficient way of checking for new messages and it kills battery life. Do not use it.
My Atrix battery life has been great so far.

cool, thanks for the info! I've never used it before I just use trillian but its what she downloaded.
My battery life is impressive. Yesterday off of the charger at 10am and I didn't charge overnight. When I woke up today it was still at 40%. I did a ton of downloading apps, setup, playing games and web browsing including flash videos. I played a 14 track cd from it when I went to bed, but I had it in airplane mode while sleeping. I use the apps for FB and Twitter instead of having Motoblur do everything. My brightness is over 3/4 too so I'm not handicapping the device for battery.
Hmm interesting..i have been getting HORRIBLE battery life. Off charger at 7am, by 12 i was at 20%. Some background data but ive tried to limit all refreshing apps to once a hour.
ok I don't know how to check useage by app but...
under "battery manager" I can get to a screen that looks like my captivate battery useage screen.
unplugged at 70%, useage is as follows...
time since last unplugged:3h 27m
Display: 50% Time On: 30 mins
Phone Idle: 36% Time on: 2 hours 54 mins
Cell Standby: 16% Time on 3 hr 23mins
Currently sitting at 30%
I took mine off the charger at 7 this morning. After very heavy use, and auto sync with facebook and gmail on. I'm at 30%
By heavy use I mean downloading apps, emailing, texting, gtalk all day.
I would say it's pretty good. Much better then my nexus one.

i expected it to be very good, its huge! The whole reason i'm posting this is to see if there is something wrong with her battery. The screen is usually the biggest battery drain on my phone (samsung captivate) but hers was only on 20 mins.
From my battery manager:
1d 3h 26m 13s since unplugged
That is 27.5 hours, including a whole day of heavy use. I'm at 15% battery.
This phone kicks ass.
I'm so giddy right now. I've ordered an OEM battery for my Vibrant, and i should be getting it any day now. The reason for me ordering a new battery is limited usage time. Lately when flashing any ROM, I make sure It is at 100% charged. I will normally get about 4.5 or less hours of usage - using a little app named 'Battery Left'.
I don't use a task killer. Ever. I know this has some controversy signed to this, but the Android OS is engineered without issue regarding this.
I Use WiFi whenever I can (uses a fraction of the power 3G radios use). When I CAN'T use WiFi, I make sure it's turned off so it's not wasting power scanning for hotspots.
I make sure GPS is off whenever i'm not using it.
I set display timeout to 30 seconds, set brightness to Auto, or manual and the lowest. Little trick, if Brightness is on manual, you can adjust it on the fly by swiping left or right across the task bar.
I let the battery TOTALLY discharge at least once (twice is better) and then charge to full. This doesn't condition the battery, this just calibrates the battery metering software, so that it knows for sure where zero is, making the metering more accurate.
I try to use a darker colored wallpaper, blacks and reds and deep greens and blues use less power than lighter tones, and white is the worst.
I get a half-day out of my rooted Vibrant on T-Mobile, and I actually use it as a phone (amazing huh?), PDA, game machine, ebook reader, etc, it's not just in my pocket on standby. Battery life has nothing to do with it being unlocked/rooted.
I understand the biggest reason why people think THEIR particular smartphone has some sort of battery problem: They just got it, and are using the hell out of it. We tend to not set it down in the first few days/weeks, we're always fiddling with it, showing it to our friends and co-workers, etc. Once the new and shiny wears off, and we settle into more "normal" usage patterns, we start noticing that we get a lot more battery life out of the device. Some people think that the battery is now "broken in", but the truth is, the USER is broken in.
Some of my POWER hungry apps I use on a daily basis is 'SportsTracker' which I use riding my bicycle to and from work (7.3 miles one way). SportsTrack uses my GPS and tracks my ride in REAL time. It sends a link to Facebook and Twitter, where my friends, and family can watch me go. This app uses about 17% of my battery - one way. So, at the end of the day, just using SportsTracker it uses at least 35% of my battery.
Speaking to the heavy users, how many hours do you normally get using your Vibrant?
With 20-30 calls a day, 20-50 texts, dozen or so emails and listening to music and just geeking on the phone Axura 30 hrs before it is 15% Trigger 24 hrs before 15%, but then, that's how it works for me. Since I got rid of stock roms, I have had ZERO battery problems, I only use Task manager. Deleted all the bloat and I have screen set to 50%. Battery is no longer an issue
With Bionyx 1.3 I let the phone sit idle (exchange email running in the background though) from 8AM and till 4PM it took only 15%
Skype+music+movie for around 1 hours and it's down 15% more (now 70%)
I guess it'll last 1.5 day normal use and 2 days idle use

That's a great battery life. My bionix eats more battery on almost the same usage. I have around 76 user apps installed and some bloater. One thing I have noticed using system panel is when I sleep, my phone sleeps with me and uses an average of 1% battery per hour. Is that good? I still I think im not getting optimal battery life when im actually using the phone.

You guys think that's good battery life? Nah, this is good battery life.
I always got 20-30hours a charge with most of the Bionix roms. However with Bionox 1.3 I struggle to get more than 12 hours with the same usage. I did notice that new app BLN (using your soft keys as notifications) was reported on some other roms as a battery drainer, so I have uninstalled via Titanium. I will report back tomorrow if that is the issue. I still use KA5 modem, so that part has always been a constant
Weird. I'm on 1.3 as well. I'm 15 hours into my charge with normal usage on 3G/WiFi and I've got 25% left.

I'm 15hrs in running Bionix-v 1.2 and i have 42% left. That's with GPS on all day....phone in pocket from unplugging to about 3:30pm. Then only light use.
Days that I use heavily I'll have to plug in around 4pm. I'm not too happy with my battery life. I love my phone...but my old iPhone 3G had top notch battery life! lasting 3 days without charging.
Is it not weird how these times fluctuate so much between users?
Will the new Galaxy S 4G battery fit in our phones? Or will it even be worth it?
Do you have the superpower app? It saves my battery big time when phone is sleeping.

I ordered a batter charger, two spare regular batteries and one spare extended battery last month for my vibrant.
Now I keep a spare charged battery in my pocket and I no longer have to plug my phone in anywhere I go. I just swap batteries and put the dead one on the charger when I get back home.
If I am going to be away from home for more than 24 hours then I put in the extended battery which gives me about 2 days worth of use.
Its a bit of a pain to have to be down for a minute when the battery is dying, but I am more content using the phone this way since I can now keep it with me instead of leaving it upstairs or on my office desk to charge.
My phone is on the stock KA6 kies and from 8-8:30 it is off the charger on 3G. When I get to work it is on WIFI with WIFI Calling(no signal indoors) from 8:30-12:00 and goes back on 3G. then at 12:30 it goes back on WIFI(calling) and sits like that till 5:00. Usage during that time, some email viewing, 10 txt or so, 5 min phone calls and that is it!! from full charge at 8am to 5 pm I'll be at 45-50% battery left and what you read above is all I do with it all day. Battery life is horrible. Not much I can do(unless someone has an idea to fix the issue) as I need WIFI calling otherwise why have a cell phone?
Food for thought

So 16 hours with 3G and WiFi Calling on all the time...on the STOCK Samsung crap? Thats pretty awesome man. WiFi calling is a HUGE drain. Spend the $2 on an app called SystemPanel. It will tell you exactly what is taking up CPU Cycles which, of course, uses battery.
I go 24 hours on a charge with routine use. Granted, everyone's use is different. But I got two days with the KA7 modem on Bionix V. I see no difference with 1.3 (haven't used it enough to tell). Granted, I had WiFi Calling frozen and was on EDGE most of the time and turned on WiFi when I needed it. I've observed WiFi Calling using excessive CPU cycles when it isn't even on. Its pretty poorly coded. I recommend freezing wifi calling when you aren't using it.
