I just started to use a ROM on my phone and I'm not satisfied with the battery life at all. I've done all I can to increase the battery life and even with very minimal use I can still see my phone being almost dead in just a single night of use.
So with that said...what is your favorite ROM and how is the battery life??
What have you done to increase batt life? Cleared battery stats? Works for me on every flash.

Right now I get great life with the i9000 roms and setirons kernel....i dont turn off wifi, data, just let everything sync as normal and I see 12 ~15% drop per hr with constant use and 1% / hr at most when phone is idle

Ditto, blazingly fast with the ulf lagfix and plenty of themed i9000 roms to choose form, nothing beats that combination.
Doc's Froyo with setiron kernel. The ROM and kernel rock. But, my battery has sucked from Day 1. (As in on Stock Eclair.) I only ever remember one ROM I had decent battery life with and that was cog 2.1.4. None of the tricks have worked for me... but I'm reasonably sure I've got a bad battery. Can't test theory until payday tho. Dangit. I also have random shutdowns, 1-2 a day, which I think may be battery related also. I get that idea from reading around in the forums. As always, YMMV

I've had this ROM running about 2 days now. The best one so far for me. The only big issue I have with it is the headphone jack don't work right. I'm hoping for an update soon as I don't use Bluetooth on here as of yet and driving without some sort of headset is illegal here.
P.S. Install this. It removes the references to video chat and whatnot throughout the system.

Agreed.14 hours since unpluged,screen has been on over 3 hours and still got 48% of juice left as I'm writing this.I think the undervolting contributed alot to the battery life.

Ok, I have been flashing for a few months trying to optimize my phone. My last rom was serendipity 6.2, with sp 59 and jl2. I restored to stock (bc I wanted to try something else and hadn't done that in a few weeks) my battery life on serendipity was atrocious.. 6 hours with medium usage. (hardly any calls or messages, looking things up or reading xda briefly) . I spent today on stock, after about 20 hours of light usage I am at 60% left. Now I did flash with a full battery serendipity, wiped battery stats and cleared cache and after several charge cycles and a few days battery life was still awful. I was about to get a new battery. Now I don't mean to single out serendipity, I've had bad battery life on paragon, dilli, and a few others (this time it just got unbearably bad), but why should battery life be so bad on custom roms? Am I alone on this? I hesitate to flash again bc I'm loving having a phone that won't die if I touch it, but I miss the functionality of the device with a custom 2.2.1 on it. Advice or opinions please.

I'm having the same problem. Everybody keeps saying they've got excellent battery life and what not with custom roms but mine doesn't seem so good. Wifi is off, I've wiped battery stats, I've used the rom for several days letting everything get situated before I begin thinking about if its good battery life or not. Maybe I'm just expecting too much or I watch my battery a lil bit too much, idk it just seems pretty bad. If I stay on the internet for 20 minutes I've already dropped about 3%

The normal Batt live on this phone with normal use is between 12 to 16 hours
I'm thinking part of it may be psychological and part may be usage.
Psychological in the sense that I have an expectation of an improvement, practical in that with my stock rom I haven't reinstalled certain apps like xda and pulse where I spend a lot of time reading and thus using the screen.
That being said I was still experiencing drains of 8% or more per hour when the phone was idle, wifi and gps off.
There is a way to check the cpu's time in each state, but I can't remember where the file is. If someone can, please let me know. I'm curious if under the custom rom my phone wasn't properly scaling down.
I'll probably flash something new tomorrow morning unless I see something shiny and new in the dev forum.

So 6 hours seems a bit low then? Could it just be a cumulative effect of flashing rom on top of rom with restoring to stock?

Yeah 6 hrs does seem a bit low. There are many things that can contribute to it. If you are bouncing between H and 3g on a custom rom will drain it like crazy, I had to disable H and stick with 3g and that helped. could also look at OS monitor to find what is running in the background.
Ok, I did notice that recently I was jumping between h and 3g. I was experimenting with some of the new modems. Should I try finding a better modem for my location?

I would try others, as well as disable H in the hidden menus, and see how it fairs
@ zelendel.... so by H i assume you mean data... i see alot of back and forth when data is on. i know when data is off i'm still using wcdma from the gsm status, but it doesn't show the 3g icon.
i need my data because i'm from the states but living in australia and alot of my comunications are thru email/facebook.
when i look at battery usage i see rarely more than 5% from cell....usually 90 something from display ( i fiddle with it alot).
can't expect too much cause it's a powerhouse with a tiny battery........
for me the big Q at present is... can we top up the charge regularly or is it always best to let a full cycle run? if i knew it was fine to keep it topped i'd stay 50%+ most of the time i think................
It is not great to keep it topped off. The lithium battery will wear out faster and lose charging capacity over time. this process is sped up the more time the battery spends at a high charge

Visit the Samsung web site and read the battery specs for the Captivate. The stock battery is only rated for 5 hours and 50 minutes of active phone use (which means the display is active). In sleep mode (display and other features of the phone are shutdown) the battery is rated for up to 300 hours (12.5 days).
I have NEVER seen a stock Captivate last for over 3 days in sleep mode. As for active phone use (display is active) my experience with several of the custom ROMS (Cognition, Paragon, Andromeda, and now my favorite, Continuum) is that the battery life is either on par with the stock ROM, or exceeds it. The kernels on some of these custom ROMs are more efficient than that of the stock ROM due to the many tweaks and cleaning up of bloated apps and code by the developer.
I can't bring myself to keep a stock ROM now that I have used some excellent custom ROMs like those I name above.
As for flashing custom ROMs and seeing fast battery drain goes... I have had that experience with those I listed, but usually I was able to resolve the issue by ensuring my battery was at 100% (meaning showing that amount both on and off) and reflashing, or finding the cause of the high battery usage and going from there (e.g. I have had to reflash modems). Another thing I do, mainly out of habit from compiling code and deploying it in dev and test environments, is to make sure that I am working from a known good baseline ROM before flashing a custom ROM. In this case I always return to the stock ROM you can flash through Odin One Click. That way if you have battery problems after flashing a custom ROM you can have a good idea as to what is causing those problems. This is, of course, just a matter of personal preference. Some have repeatedly flashed one custom ROM over another with no issues. YMMV

No what I mean is disable HSDPA I think is the term lol. Sense you go back and forth I would say to disable that and just use 3g only.
If you don't know the code to get too the menu download sgstools it has the hidden menu keys.
Sorry but where can I find the hidden menus?

I am the opposite, I got horrible battery on stock. Could not even make it through my work day without it dying on my way home unless I charged it midday. Now I am running Serendipity 6.2 and unplug at 7:30am and it is now 8:30pm my time and I have 30% remaining....
I have also tried other customs roms with noticeable improvements in battery life over stock but for me Serendipity gives me the best performance and battery.

i used about 50 phone call, 2 hour websurfing, email sending, checking.
i still have 41% left, 1day 10hour 50 min.
Could I have a faulty battery? I rooted and rommed cuz of my battery life being terrible but It still is bad

I had the exact same issue as you. I tried Darky's 9.3 first, then Serendipity 6.2, then Cognition 4.2.1. Each had major battery drain, meaning 6-8 hours with moderate use, and even without any usage it would drain 25% over 3 hours.
Use One-Click to flash back to stock JF6, then immediate do a Master Clear from the One-Click program after it has finished booting. Obviously move everything to an external SD or the computer prior to all of this, and make sure the external SD and SIM are out when flashing.
My battery has lasted for 14 hours today, and I'm only down to 54%. This is with about 1hr 20min screen on, ~30min voice calls, and always connected via 3G/H with background sync on, weather widget, and moderate web browsing.
Current setup: Serendipity 6.2, Speedmod K13C, JK4 Modem
Trying again
I couldnt keep myself away from custom roms, how i missed tethering, the custom theming, non marketplace apps and so much more...
Im trying Dilli's 7.1.1, bump charging at the moment...
Last night I drained my battery to 5% when i finally fell asleep... 6 hours later it was at 4%. Finally it drained and would not power on at all. Not even the backlights. Plugged it in for an hour and thought to take the sim card out so i would have a phone for the hours it would take to charge. When i plugged it back in the phone jumped from approximately 10% to 40% charged...
Oh well.
I have also been bouncing around flashing diff roms like crazy. I have to say though, I am using Continuum v4 with Hardcores speedmod Kernel K13D. I have been doing pretty good on this combo. Lasts for most the day with normal use.
Hello,
Anybody who flashed tons of different ROMs, can you comment which ROM provided best battery life for you. I'm not looking for absolute numbers but comparison of different ROMs as far as battery drain is corncerned for the same user.
Is less about the rom and more about the kernel and u/v u/c in my opinion...radio can have an effect too
Currently I am on coca-cola with dag's .3 kernel using the Gideon battery saver script.
I like using that on the quickwiz rom too

Ive been flashing a lot of roms the past week. I'm currently using [ROM][UXKJ2]Buoyancy v1.3.0||Rogers/AT&T||[1/25/12]
Deff the best so far. Very quick and it's been 11.5 hours and I'm at 57%! Kudos to jomeister15 and his team!
You are on ATT network and in LTE enabled zone?
Nexus had the best for me. I also hear Buoyancy is great as well. Sky ice cream sandwhich is what im running now but i charge my phone a lot. An update should be coming soon for battery life fixes on it though.
radio on or off?
I've been running TPC v3 on my 727R for about 2 weeks, with his oc startup script. My battery life wasn't so great until I decided to start turning off data while not using it. Made my battery life go through the roof.
From full charged, I was still at 69% 20 hours later. Mind you, I wasn't using it that much but even still.
Which leads me to wonder: are people actually turning radio off when not in use? Because with it on, I can't get anywhere near those numbers.
What will you be missing if background sync is off while screen is out? everything relying on push notifications will stop working or will be there some other noticeable changes?

I use skyICS and I get pretty good battery.
The pic is of my first battery cycle on skyICS, with pretty decent usage on it. The red little bit at the end is me trying to kill the battery. I had wifi on, data, sync, flashlight, and ran quadrant standard non-stop for about a 30 minutes.
I think a lot of it will depend on how you use the phone. As mentioned above, simply turning off data saves you a lot of power. Going into airplane mode saves even more. I lose almost nothing in airplane mode (I put it on at night). You can get an app in the market that will auto turn off settings for you if you're too lazy to do it yourself.
so I've been bouncing back and forth between 2.3.3 roms and CM7 based roms lately and one thing I've noticed is that on all the cm roms I've used the battery seems to drain really fast while using the phone (web browsing, texting, anything basically with the screen on) compared to stock based roms. I can litteraly watch my battery % drop while I use it. I've tried various kernels, oc/UV, keeping screen brightness low, none shows too much improvement.is this a known issue or is it just my phone?
It could be just your phone. I'd say completely wipe your phone, and reinstall everything. If it doesn't help, then it might be the battery. But I would usually (with CM7 and Faux's DS kernel) average around 12 hours.
I'd also say give an ICS rom a try, I average around fifteen hours moderate to heavy use.

Freeze all apps you don't use or need... But I always got horrible battery life regardless.

I did that too. I actually uninstalled pretty much every app I didn't use regularly and any stock replacement apps like yahoo mail app, swiftkey x, and a few others... but it didn't make a difference. my drain isn't too bad in standby, about 1% per hour, its when I'm using the phone. for example, say my phones fully charged, if I unplug it and surf the web, go on xda app, Facebook, and play a couple rounds of Scramble w/ Friends for lets say an hour straight, ill be at probably 40% left or less when done. on a stock based rom I'd say I'd probably be around 60% or more left. I'd stick with 2.3.3 if the camera wasn't so crappy but I take a lot of pics so no go.

Ive noticed this too. i have great battery life on any 2.3.3 any other roms seem to drain pretty fast. However i was able to tinker with some custom kernals (faux and morfics) and get the battery life to be noticably better on 2.3.7 roms like Singh,EB,CM7 etc. Bigger battery helped alot too. i use the Gorilla Gadgets 3500 mah. at least 2x more battery life than before easy.
Hello,
I can't post in the BlindIce topic so I hope it's fine here.
I've seen only good reviews about the battery, that's the main reason I installed this ROM, but I seem to have a problem, my battery drops like crazy. In ~2h it already went down to 86%, and all I did was send 2 SMS. On Endymion I didn't have this problem.
And I also have a problem with the stock browser, it's moving like a snail, but the main problem is the battery, firefox/chromw is working fine so I can live with that.
I'll upload the battery log after I get home, if needed.

i was also very happy with it despite minor bugs but eventually many things sent me back to endymion i can guarantee pretty soon you'll be back on endy, ics roms are nice but until the kernel comes out there isnt really one that can rival endy
anyway back on topic, check things like widgets? especially things like youtube widget i just took mine off, having it there means its connected to the net cycling through the subscriptions constantly, thats an example most widgets add to drain quite well, check your syncs, which app syncing for how long, can you do it manually etc, weather apps are they syncing to frequently, which apps are using location? using better battery stats i found google locations is used in many things without me even knowing, all of these things should be checked and configured on any rom, there is nothing really specific, maybe your 3g is using up the battery? try switching to gsm only.. finally have you calibrated the battery or more specifically the phone; so it reads the battery accurately.. thats all the things i can think of off head to help
Thanks for your reply.
Anyway, all the config was done and there was no widget running so I guess it was something with the kernel/ROM that my phone didn't like, considering that I'm probably among the few or the only one which had such an issue.
And like 3h ago the battery was hot as hell for no reason, only Y!M was running, it literally burned my hand, there's still a little red spot, so idk what was the reason or what happend but I went back to endy, after the 3.0 kernel will be out, I'll try again, until then thanks and keep up the good work @devs.

Any widgets (or sync's) running on your phone?
If so - how many and what kind?
The battery isn't that bad for me but on all of the ICS ROM's that I've used the battery drain issue is quite bad. Then again, I was using Virtuous Affinity for a while and the battery wasn't brilliant on that either so I've come to the conclusion that I will probably require a new battery soon.
But still, the battery on my phone on BlindICE has been better than on yours but I'm reluctant to switching from it now
