Has anyone having issues with battery runs out drasticlly. Charge it and then with in minutes its dead. Get a full charge turn it off and back on then its dead.
I had that problem with my epic after flashing a custom rom. battery needs to be calibrated if it was not flashed at 100%. you can download battery calibration app from the market place.
Ya calibrate will help the readings but don't expect amazing battery. I have the seido expanded battery and it still can't make a day of heavy use.

i installed the syndicate frozen rom 1.1 and now enjoying a battery that still has life after return home from work (12-14 hours unplugged....medium use....about 40% remaining when i get home)
I'm using syndicate 1.2 with genocide 2.0 undervolted extensively on conservative and with the 3300 mAh battery I don't get that

I had this issue on a few ROMs, specifically the Anonymous i3. I would charge all night and by the time I got to work (1.5 hours on the bus) I would have only 50% or less battery from listening either to Pandora or other music and with 4G off. It's infuriating. I have not calibrated my battery as of the moment, however I did go to the RandomRom and my battery life is phenomenal in comparison so I would recommend (and my recommendations carry no weight because I am nothing more than a casual user who only recently began rooting) looking at what you are running and checking battery drain on other ROMs.
Your specific issue is calibration. Its that simple, its misreading you battery status

I figured that was likely it, but never worried about it since I still got good usage without ever calibrating. The anonymous i3 is the only one that didn't have decent battery life for me. Random has been the best so far, gets me about 10 hours with basic use.

I have a work issued iPhone 4 and the fascinate. I fully charged both phones and put them on my desk at 3pm yesterday and did not use them at all. This morning the iPhone was at 98% charge and Fascinate was at 30%... Both phones sync with a exchange account and both have very good signal strength at my home.
I've checked the battery usage on Fascinate and the top 4 items are: Display 49%, Media server 15%, Cell standby 14% and Phone idle 9%. How can standby and idle use so much battery? I also used task manager and killed all running programs yesterday.
So what could be causing this? I can literally watch the battery percentage click down 1% for every couple of minutes of use.
Running Blackhole v1.3 with JT's Stable 11/11 kernel.
After a full day's worth of average use my battery (off the charger at 9am, on the charger at ~1am) My battery rarely drops into the orange.
You mentioned you had a task killer, I'd blame that first and foremost. Also, I think there was something inherently wrong with your test... if a screen that was off used 50% of the battery...
It's also entirely possible that you're just trolling, because I know from roomate experience that his phone if left alone is not at 98% battery after 24 hours. Also, APPLE lists the standby time as up to 300 hours. That would mean that at best you'd be looking at an ~8% drop after 24 hours.
That 15% used by the media server probably didn't help much. What all was your IPhone running in the background...oh wait, nevermind.
I dunno about the iphone but I feel you on the fascinate. I left mine off the charger, no screen on, with airplane mode on, and the battery dropped 50% in 7 hours. With absolutely no use. I'm lucky to get 7 hours during the day actually using the phone. Three display is always around 70% usage of the battery even though I have brights all the way down and always turn off the screen.

I use Ultimate Juice Defender and I take my phone off the charger at 6:30 a.m. and by 5:30 p.m. I am usually at 80-90%.
Not sure, you might just have a bad battery. I have been off the charger for almost 7 hours now (early day). I have been messaging (google talk and sms) had WiFi/BlueTooth/GPS running constantly I rarely turn them off.
Have been using google maps off and on for at least 20-30 minutes as well as voice. And about 45 minutes of phone calls.
For me:
Display 29%
Standby 26%
Idle 16%
android 12%
and then bluetooth, LauncherPro, OS and Google rounding out the remaining quantities.
Oh forgot and a solid 20 minutes of angry birds
i use a task killer but i allways set system apps to ignore except camera and google maps and autokill stuff like file explorer, root explorer, games and stuff.
I get up at 4am use my phone pretty often little of everything and can make it threw a day getting homr at 5pm might be 16-20% battery left but still good imo.
Removing bloat might help?
I went to lunch and played with the phone while waiting for the food. Just red some news and surfed the web a bit. Before lunch the battery was at 34% now its at 16%, I think there definitely is something wrong with my phone. I wonder if a different kernel would help.
Try resetting battery stats and reconditioning the battery. There's no way it should drop more than a handful of percent asleep in airplane mode... Maybe one per hour.
Sent from my Voodoo-powered Fascinate with XDA
How would I recondition the battery? I've reset the stats with a fresh battery before and have tried different kernels. I have two batteries and it's the same with both. I even took it to verizon but they said there was nothing wrong with it even though it dropped 30% on their test call.

I'd definitely say its just a bad battery. My fascinate stock destroys iphone battery life. With a UV kernal it at least doubles iphone battery life. My work issues iphones so I get a daily comparison.

I would say battery as well, my phone has been off the charger for 20 hours now and I'm at 50%. It's my work phone so its a stock kernel.

I was in your boat. The first fascinate I had would be unplugged at 6:30am and dead at 3pm with very little usage. I hated this phone. I got juice defender and it would last until 6 or 7 with very little usage, and as I used the phone I would watch as the battery rapidly ran dry. I got two other fascinates and it was the same issue. Then I got the one that I have now and it uses almost no power in standby. with juice defender and it being on idle, I can get almost 2 days out of 1 charge. I know it sounds ridiculous to you, with your experiences and it being a smartphone, but samsung has done some kind of magic here. Keep taking your phone back until you get one that uses very little battery on standby. Apparently there are a lot of units with bad batteries. As of this writing, with Ultimate Juice, my phone has been off the charger since 5:30 this morning, did some flashing, which uses the battery open throttle, installed 5 apps, played angry birds for about 35 mins and I am at 91% at 10:09
Well my 30 days are up, verizon found nothing wrong with it and I have 2 batteries.

Try a different big red CSR, and if you fail again, try bricking it in a fixable way after backing up. If you come in with a force close loop, I but they won't have any idea whats going on and you'll have a high likelihood of getting a new phone. If it fails, just reflash and try another tack.

I would honestly try one of the Stupidfast kernels if you really want bettery battery life, but honestly it sounds like some kind of hardware problem.
Stupidfast kernels really do give me better battery life. I was skeptical at first but after wiping the battery stats and rebooting after I unplug I've been getting GREAT battery life.
I'm a HEAVY user and I unplugged at 11 AM and 9 hours later I still have 31% left. With ANY other kernel, my phone would be at <20% by now, probably under 10%
I'm a believer, and will be donating come Wednesday when I get paid
Tried them all. But the stupid fast does seem to do the best job.

I will say one thing, with the new DJ05 update my battery life is great. Best I've ever had. So when it is finally pushed to u enjoy. I feel like there has been some tweaks made in the upcoming update that make even a bone stock fascinate one of the best around.

Hey guys, I don't care if the rom is Sense or not. I just need the best rom for battery life. Or best rom/kernal without underclocking or sacrificing speed. All input is helpful guys. Thanks
Nobody? Man is this forum dying? 4 months ago, this would be 2 pages by now.
I just got 46 hours up, 5 hours awake on rEVOlution 2.1 with the stock .17 kernel with the stock battery
I've pulled over 32 hours on Virtuous Sense with the customer Virtuous kernel. Granted I also have a Seido 1750 maH battery, well worth the investment though.
EDIT: I had approximately 15% life left at that check in also, so I could have kept going. Next time I'll take a screen shot.

This one is best for me. I don't have to put my phone on the charger most days until I go to bed. If I ever use GPS in the car, I keep my phone charging while using it, with moderate use I can get by the whole day from 6 am till I go to bed.
I run Uncommon Sense 1.1 with SetCPU and JuiceDefender; I've been able to pull off up to 35 hours between charges with the stock battery and kernel.
I get 4 hours tops.

I get great battery life with jk6. 5 hours idle and didn't drop even one percent, but it drains fast if I use wifi.
What if you delete MediaHub and DRMua?
I seem to get much better battery without those.
I also enable WIFI during sleep... it's in the advanced settings under wifi.
And of course I remove all of the other bloat apps.
JK6 with all the crap removed and I average 18-24 hours with moderate use. The lowest I've seen is 12 hours and I had the screen on for almost 7 of those.
Looking forward to when we get source code and can run an undervolted kernel.
I get really great battery with JK6. I suggest you to do battery conditioning.
JK6 has great idle battery life for me but as soon as i start to use the phone for low activities it drain faster. By "low activities" i mean as in making call, use map, navigation, changing settings.....
Here is my usage report:
3h since unplugged from over night charge
73% left
Display on for 45m 19s (lowest setting w/ auto brightness turn off)
Voice call 45m 21s
Cell standby 3h
Phone idle 2h 15m
To me this was worst than when i was running JI6. Also i lost 3G every now and then in the same area that i travel everyday.

Using maps and navigation are some of the most power-consuming tasks you can do with this phone. Navigation in particular killed my Vibrant dead in a few hours.
The kswap process eats a upon of battery when in use on the jk2 roms. I thought jk6 had this fixed, but it may just be better on the custom roms. I get great battery life on my jk6 rom.

I had similar battery life using various custom kernels. Installed Aux. 2.1 with stock. With heavy use I am running around 8 hours. Normal use around 12-16. Those other kernels will eat your battery alive. Try a stock kernel. Conditioning doesn't do crap.

noticed this also, doesn't really make a difference to me.
Most of these problems are user error. I woke up today with around 70% this mourning at 7am. Its 12 hrs later and im at 42%.
My Day:
combined 45min of calls
atleast 30 txt message
Ton of emails and they sync all day
Started my music player at 9 and didnt pause until 5pm. playing out of speaker
Browse the internet off and on all day
downloaded a 100mb mixtape torrent through 3g
screen brightness at about 60%
Probably a couple other things but app called Battery Left is telling me I have 10hrs left.
I really suggest running all stock. I need no lagfix/special kernal or anything with the newest leaked samsung firmware. Havent had a single issue since I switched to this rom.
I'm sorry, but I have a very hard time believing that, ALL THAT, only took 28% battery.
17%after a couple more torrents. Not wirth trying to prove but the stock rom made my extended battery worthless besides special occasions.

Thanks for the help. My battery died after four hours as expected. Plugged in and reconditioned and let it charge till it was full. Now It's been about five hours unplugged and I'm down to ninety six percent.
However as some of you have posted my battery drains VERY fast once I use it sparsely. It dropped almost 5 percent after a few mins of browsing the market. Weird. But whatever standby is amazing.
Hey can someone please tell me in which rom the battery lasts longer???

Why would turning on wifi improve battery life?
The idle time on Unity is very good. I'm somewhere around day 2-3/4and just now getting to 50%
However when you're using it the battery tends to die pretty quick.
Pyromod! its amazing, I get about two days battery life.
I never worry anymore, If i'm going out of the house around 5 PM with 20 percent battery life, I'm good for the rest of the night and morning.

That's how it is. The firmware interacts with the battery in a way that any % over 90% is considered a full charge, so sometimes this comes away with the phone sitting at 100% for a long time (up to like 2 hours for me if I don't use the phone much), then draining normally. It doesn't drain fast, it just drains fast compared to the battery sitting at 100%.

Not true. CM6 had a drain rate of 3%/h on idle with no connections and me popping it on once or twice an hour to get a text.
Cm7 was around the same. All stock clock with downclock with the screen off to around 500mhz.
Unity's idle rate is only about 1%/3-4 hours. It's insane.

No, I mean you clearly are going to drain fast when using a phone compared to idle.
And any ROM with a proper kernel can be undervolted / underclocked with apps to disable data in order to drain less battery in idle.

I can't tell if you're kidding or not, but the phones and ROMs I've seen all exhibit this behaviour. The OS will report the battery at 100% for a long time, as if the battery has more capacity than the OS knows about. A more accurate estimate would be to wait until you're at 99%, and then see how fast the meter drops. Better yet would be to use something like Current Widget or Battery Monitor Widget to record real-time current draw, then calculate how much energy has been consumed.
I wish there was a way to calibrate what "100%" actually means, but I don't think that is possible, since it is a hardware limitation.
Right now I'm using RoyalGinger 3.0 on my HTC Panache.
I know that it's based on CM7, but if I switch to the actual CM7 Nightly or Faux's ROM which I'm also considering, will I get noticeable improvements in battery if I maintain the exact same usage patterns?
Hmm. That's difficult to answer. RG has really good battery life. Faux's ROMs focus more on raw speed than battery life, but still give decent battery life. CM7 doesn't have as good of battery life as RG, but usually lasts all day with all but heavy usage. At least, that's what I've found. Your mileage may vary. Your choice of kernel is important, so keep that in mind.
Sent from my HTC Glacier using XDA App
With moderate usage, I average roughly 11-13 hours using Royal Ginger and the kernel it comes with. Couldn't really find any benchmarks so not sure whether this is typical or not
This is with brightness set at the absolute lowest (Display On roughly 3 hours), Wifi never on, GPS never on.
OC'd at 1.1/245 smartass. Trying out On Demand to see if there is any difference
Well I know its not RG or CM7 but I run Virtuous Unity 2.35 and I am averaging 16-20 hours of battery with a average of 2.5-4.5 hours of display. It all depends on what you do with the phone.
There are many ways to help improve battery life. For instance Battery Calibration on the market. Follow those instructions and you wont go wrong. Another being Juice Defender (paid or free). A friend of mine is using an AOSP rom for his Evo and is averaging 30+ hours with Juice Defender.
Had no idea about that Battery Calibration app. When I flashed RG (and now MIUI), all I did was let the battery run down to 2% through regular usage and do a full charge until 100%
Flashed MIUI the other day, which I've heard nothing but good things about, including battery life, and am following the instructions of Battery Calibration now.
Not the biggest fan of Juice Defender. Had used the free version for a few days, and I found that sometimes it wouldn't re-initiate my data after the screen turned back on (which seems to be one of the more prominent features to save battery)

I agree with the Juiced Defender, that's the reason I don't use it.
For instance, when we are car pooling to school he has problems keeping pandora playing because Juiced kept turning data off. So he disables it when we are driving.
You don't have to use Juice Defender, of course, but the reason it re-initiates data when you turn the screen back on is that it turns the data off when the screen turns off. Turning the data off is what saves battery.
