Right now im on froyo KC1 and 6 hr idle night only consumes about 5% (with GSM off and WiFi ON) and with normal use, i can use the phone for 2.5 - 3 days with a full charge.
However once i installed KF2 (gingerbread), 6hr idle night consumes about 30 - 40% (with GSM off and WiFi ON) and the phone is dead within 24hrs with normal use.
Is that normal with gingerbread or is there any fix for this?
i dont but i do know when i had gingerbread (kf2) i saw a big diff in battery life compared to using something like kd1. the kf2 was usin like 50% more than the kd1
Kc1 has been solid for me, tried the kb1 only went four hours with medium use

Installed GB 2.3.4 y'day and still battery performance is way less than KC1. Does KC1 show the correct battery level?
Guys, don't forget you have to calibrate the battery and use it for a couple of days first.
I never used KF2, but 24 hours with regular use is already excellent battery life with Android.
could u please let me know, which is the best/easy calibration method for SG4G?
Battery Calibration. It is in the Market. Download and follow the easy inductions. It takes a cpl of days after calibrating for the phone to "settle in"

You're exactly right. I have been amazed by KF2's battery life! I've consistently experienced between 26 and 30+ hours of battery life with moderate use with KF2. It's ridiculous (compared to what I've seen so far with this phone).
I did two things that I think added to the already decent battery life for KF2.
1. I installed SetCPU and set it for powersave at 800-1000mhz (with powersave screen off profile of 400mhz)
2. I also installed this app called AutoKiller Memory Optimizer - running in background with default settings (not like the other task killers, trust me).
Man, I believe I've found my phone's sweet spot. KF2 is running smooth as butter, pretty as ever, and running like the energizer bunny (well, relatively speaking)! I'm scared to flash another rom, now.
Just FYI... I flashed the Deodexed ODIN version of KF2. The best I've flashed yet! (Thanks, corradokng!)
My KF2 battery life just keeps getting better and better.

So my friend who bought a captivate at the same time as mine (about 8 months ago) has been using stock rom (JF6) for a while. He basically just makes 10-15 mins call a day, checks weather and livescore sometimes, no background data, and he told me that he got at least 4 days!!! Right after he upgrade to the official Froyo, his battery life drops down, and he said not even lasts a day! I helped him install the Serendipity 6.3, told him to run for several days and recalibrate the battery. He reported back to me that with the same manner of using his phone, set the screen brightness to the lowest, his phone last from 6:00pm to 12:00pm the next day (about 18 hours). I then helped him to come back to JF6 yesterday afternoon and up to noon today, he said the battery doesn't change (means it drops less than 20%).
So does it means that in term of battery life, the JF6 gives us the best? What in Froyo makes it that bad in battery life? I might want to go back to JF6 to test. For now I'm using Phoenix Ultimate and got like 12 hours. Of course I use a lot of google voice, email syncs etc ...
I love Phoenix Ultimate. I made the switch to Phoenix Unleashed though. Much quicker. Man that is a great rom.

I agree with this statement
Hmm... I haven't really noticed a huge difference going from ROM to ROM. But I do know that on Andromeda3 in the 17 hours and 17 minutes since I unplugged my phone last night I've used 22% of my battery; this is with WiFi and the GPS enabled.

same here, I noticed that, I use completely stock eclair and official froyo rom, my cappy never tried to flash any rom, so I can only compare the stock eclair and official froyo's battery performance.
my eclair last for only about 18 to 22hrs, I'm a heavy user, after the froyo update, my battery can last up to max of 12hrs, that sucks!
Sent from my SAMSUNG-SGH-I897 using XDA App
I am on a custom ROM, and with 2-3 hours calls and 1-2 hour display with 3 accounts pushing in mails, I easily get past 48 hours.
i never found that to be the case. the battery life on eclair was fair but not great for me. i used the phone a bit heavier but found it to be similar to my iphone 3g or slightly less if it was being used most of the day. ok so i could get 4 days on the iphone but i really didn't use that phone much. the cappy even with light use wouldn't go more than 2, it used a bit more on standby than the iphone. every phone is different so i cant say that your friend doesn't get 4 days but in every day use i dont see froyo using much more battery on standby and probably uses less for me during use.
the best battery life on a rom i ever had was jk3 from the i9000m. it was perception something and was very light. the rom was also fast and feature packed. battery life was about 2.5 days on average. the next best was a tie between andromeda and the jh2 leak 2.1 with unhelpfuls kernel 1.4.1 and a lot of undervolting and the gpu underclocked for frequencies up to 600mhz and overclocked for 800-1200. that kernel ran great but was overshadowed by 2.2 with jit. i wish unhelpful would make a 2.2 version because his undervolt never suffered from charge death and the phone would tolerate much lower voltages. plus control over the gpu was a nice feature.
some of the 2.2 roms may eat a lot of power on standby but if the use is that light it should still get a day+ but i feel under use there isn't a difference i can detect consistently.
I don't like to get 4 days by just make phone call, because then why do you need a smart phone? I'm just wondering why that kind of thing happens? What in 2.2 eats battery that 2.1 doesn't? Ok, improvement in performance can shorten battery life, but should not be that whole difference (I mean from 4 days to 1 day)! That guy he even keeps all the crap wares from AT&T and doesn't have any task killer installed!

Really? I'm about the same usage as you and my Captivate cannot last longer than 18 hours...
Just wondering if anyone can help me understand how there can be such a drastic difference in battery life between Froyo and GB. I've been using BAMF Roms mostly since I rooted my T-Bolt and with above average use on 4G half the day, on Wifi the rest, and get 20>24 hrs battery life. I flashed All the GB Roms after each update, because the lockscreen keeps calling me back lol, but I'm lucky if I get 6 hrs usage with the same basic setup.
I charge my phone every morning when I wake up to 100% and rarely have to charge again until the the next morning with BAMF 1.7 unless I'm flashing mods or streaming a lot of audio and video. I went to sleep at 11:30pm last night with 19% battery and woke up with 14%, insane! With BAMF 2.1 the night before, I not only had to charge my phone 2X that day after very little usage, but went to bed the same time with 100% battery and woke up with 47%. That was with everything turned off, wifi, mobile net, and underclocked to 245mhz with the screen off.
I would just like to know how there can be such a big difference, especially with standby time. Thanks.
It is a known fact that GB is more resource hogging than Froyo. Plus the fact that the GB builds we see here are all based on an alpha leak.. which may not be the best representation of GB. It perhaps has to do with how GB handles memory and how much resource it sucks in to accomplish that.
Just my theory.
I guess what I really can't understand is the standby time. If the screen is off, shouldn't the phone be using less resources? 5% loss on Froyo at night compared to 53% loss with GB, seems like a huge difference to me.
Having some serious battery drain too since going to 2.1. Was thinking about trying a different kernel. Have you tried anything. Trying to find a link but think I saw some posts that Imoseyen's kernels were pretty good.

53% loss overnight in standby tells me you probably have a bad app somewhere.
Mine typically loses about 15-20% max overnight on GB Roms.. (and I've used GB theory, Liquid Roms and Gingeritis)...This itself is more than Froyo Rom which for me has been typically about 5% loss max on standby overnight.
Most importantly.. when I am working on the phone.. GB Roms tend to lose charge a lot faster than Froyo Roms.. which is where the real pain is.

I've seen the same thing. After about 4 hours yesterday on my extended battery I dropped 2%!! With a GB ROM I lose 10% per hour-ish. I'm just sticking with FroYo until we get a better GB leak that is more stable. I was on GB/CM7 on my Inspire and the battery life was great so I know GB isn't as bad as it is on our device we just have an early build of GB. It will get better hopefully sooner rather than later.
I'm not sure if its GB or the roms but there are additional features in GB/GB roms that contribute to the battery loss. These battery tips are in chingy's gingeritis post. Go through these and hopefully these will increase your battery life. I didn't come up with these tips. Credits to Boskoel03

Other than re-flashing after the Rom's are updated, no, I have not tried any different kernals because I assume the devs know a lot more than me, so I like to stick with the kernals that come with the Roms.

Use Titanium Backup to Freeze All User apps (under Batch Option). Do this before you go to bed. In the morning see what the % Loss is.. Then you can Unfreeze them all one by one and find out the culprit.
Last night when I went to bed my GB rom had 63% juice left.. this morning I was at 47%.
Also, I am using liquid Rom w/ stock battery.

FINALLY MADE THE SWITCH TO 2.3.4 AND LOVING IT!!!!!!
I notice that most of you guys are comparing GB to stock froyo, which is unfair because of the bloat ware and froyo is not at it's full potential. What I want to know is how froyo and gingerbread ROM stack up against each other in custom full custom ROM for battery life.

First calibration, 32 hours with 4 hours screen on time.
So far for me, Froyo rooted, debloated, and running Juice Defender, has given me the best battery life, with just over 79hours as my record. That was with barely any use though. I usually get between 24 and 48 hrs with regular use though.
I've only been on Valhalla for a couple of days now, and with JD, I got 55 hours on this last charge with some light use, but I'm not sure it was started with a true 100% full battery.
Charging it now, and will see how it fares over the next couple of days.
Just posted about this on the GB V6 Tweaks thread....had 29% batt left after 44 hours with Dsex UV settings and V6 tweaks flashed over Valhalla....posted screenshot at link below.
http://forum.xda-developers.com/showpost.php?p=17317691&postcount=254
Also just in case anyone was wondering, if you want to use dsexton's UV settings, you need to flash his v6 tweaks. I tried his uv settings without the tweaks, and my phone froze up, lol.
Trying a new set of mild UV tweaks right now, hopefully I'll get through a full charge without problems.
I don't think you need an app from the market to recalibrate your battery. There should be an option in CWM recovery to clear the battery data. The phone should then recalibrate over the next few charges.

My battery drops 5% under 1 min without even use of the phone, even when the phone's on standby. After about 3 hours of moderate use (seesmic and whatsapp) it'll drop from 100% charge to about 50%. Sometimes right after I plug it out, I can see the battery drop to 99% then 98 and so on.
I'm running Pinnacle 1.3 now and I was of the impression that it was a great ROM for battery life. Before this I had a stock GB ROM, and then CM7. On CM7, the battery was also horrible.
I've run battery dry then charged it back to 100% and did battery calibration. still horrible.
any suggestions, please?

If that doesn't work maybe just try reflashing. Make sure you have 100% battery when you flash as well. I've used ROMs before that I knew had good battery life and sometimes when I flashed them my phone died fast. I remember it happening on Serendipity VII before. Didn't make sense cause I had good battery life with it before, but that flash didn't go well or something. Reflash brought back good battery life.

I'm not sure what Seesmic is but if you're doing a lot of web browsing that's definitely what is killing your battery life. The display will use more power than pretty much any app out there. I have my screen brightness as low as it'll go and I don't leave my screen on for a long time when I do turn it on. Plus the white colors of websites uses more energy on AMOLED screens.

Yes I also have the Samurai kernel, along with Voodoo. Still no dice though. I wish I could get the battery life I hear so many people talking about. I've been told to try out dlev 5.0.
Also make sure you have Automatic Brightness, Auto-rotate and Power Saving mode turned off.
i have brightness to the lowest, no auto brightness. i don't like auto-rotate so i keep it off. but i do have power saving mode on. why would that be off?
where is "power saving mode" setting on a captivate? simple questions:
1. when did you flash the rom?
2. Have you seen in settings which process/app is using your battery?

It did for me. I can't remember if I saw the battery life drop after flashing the 4.2 kernel update or not. I think when I reflashed I didn't flash anything and left it with version 3 or whatever it comes with.
Also, on Pinnacle I am using all stock stuff (kernel, modem), not the Samurai kernel or anything.

It should be off, it works with auto brightness to keep it dim and "save power" but if you're not using auto brightness its just another process running that is wasting resources.
Auto brightness is pretty useless on tw roms because that handy brightness adjustment by holding down the status bar and moving left or right.

1. Like Reamer09 says refash.....BUT don't forget to wipe data, wipe cache and dalvik cache. Wiping data and cache just before reflash.........it helps with my battery issues. I don't think there is any ROM out there with that bad a battery life. No dev would let that pass
EDIT: Just re-read.....your battery dropping like that after recharge can be a kernel issue......it happens to me on a a particular kernel (will not name ! devs all work very hard on their kernels.....) and flashing another one helped.
Ok I will reflash it. I've also noticed some lack of responsiveness while using the phone. For instance when I select an option in a menu anywhere, it pauses a bit (probably a second or two) before it carries out the selected command.
Another example is while I'm typing, I have haptic feedback on and so I feel a vibration everytime I touch a letter. The vibration is usually just a short buzz, but once in a while I feel a strange longer vibration. It's weird, really. I hope reflashing will also help with this.
I have updated to the official ICS (AT&T) and now I'm no longer getting much battery life. I had some issues with the update, so I wiped my phone and I have little to no apps.
I used to get 10+ hours of battery life, and now I don't even get 8 idle hours (so now it doesn't even last the work day). I checked Battery Usage after it was down to 20% and cell standby took up 90% of battery life.
I used to run JuiceDefender, but I reinstalled it on ICS.
Why have I lost so much battery life; how can I fix this?

I have noticed the same thing on the stock ICS. Also noticed very slow charge times using USB (possibly true with A/C charging but I am normally asleep when I charge with A/C).
Is this just caused by the bloat that they put in? I want to flash a custom ROM just for battery life at this point.

Why have I lost so much battery life; how can I fix this?

Im also seeing Cell Standby as a higher % than I used to.
install sky ics rom , this is the best battery . you can easy use more than 15hours . nexus mod 5.04 is also good . and much easier for noob to install . stock sucks .

Instigator's kernel is for AOSP (CM9/AOKP) so for ICS based official or roms you will need a different one such as mohan's kernel:

As for battery loss, there are some cases where if the flash wasnt done with 100% battery it could be reading the battery wrong and some people have had success with recalibrating their battery (look up battery calibration on play store). Now it was said that it really doesnt do anything for battery improvements and was just for stats use or whatever but for some people it helped their devices read the right battery stats.
