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 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.
I get horrible battery life with nearly every ROM Ive used on my Sensation, sometimes drains 10 percent an hour with the screen OFF. I have all data off, no wifi on, no apps running, juicedefender ultimate, and underclock when screen is off, and I read about people who can get a full day while using the total potential of the device. I had the same problem on my old device, so I returned it to T-Mobile and still have problems on the device I got in return. I dont expect to get two days on battery, I just find it crazy that I can barely use my device without the battery draining rapidly. I've considered undervolting but every rom ive downloaded didnt support it, so I was curious if you guys know of any efficient ROMs that save a ton of power and can be undervolted. I'm not very experienced with this kind of stuff and every ROM ive used has been poor on battery life, so help would be appreciated.
I am using InsertCoin ROM and it is running fine.
I used to have a 3% battery drop per every hour the phone was sleeping on stock rom and ARHD ics. Then I tried Virtuous Inquisition and it fixed the issue. Be sure to install the rom with its appropriate radio.

ICS isn't fully stable yet, but seriously.. give that a try. My battery has doubled its lifespan. I have NO idea what htc/google did, but I get about 12 hours moderate usage and still around 50%. Getting 12 hours back then was what I was hoping I could hit! Now it lasts beyond my expectations
I've also read that you tried undervolting and everything. I just stayed stock and it's great, no effort! no custom kernel, OC/UC , it's amazing. If you read through the threads, I'm not the only one experiencing awesome battery
If you must know, I'm using InsertCoin but I think ARHD and all the other ICS roms will pretty much solve your problem

Ok thanks guys ill try various ICS roms over the next week and see if there's a difference.
Maybe this is due to my lack of experience, but maybe not. It seems like every time I put a new ROM on my phone it goes to hell in about a month. I'm not a technician but I can follow directions for installation, patches, etc. So far I have had 0 long term success in installing a ROM that ends up being any better than stock after 30-60 days.
For example, I've had issues with battery drain, random booting while the phone is powered off, redraw issues, serious lag, data connectivity issues, and a few other things. It seems like its always something.
The only phones I've toyed with are my old Eris and my Charge. Is this a phone issue, noob issue, or is this par for the course? If it is par I'll end up back at stock and have mediocre performance rather than have a buzz saw that ends up needing constant tweaking and maintenance.
Btw this isn't a knock on developers. I appreciate them sharing all their hard work. I just want to know if everybody else goes through this or am I holding a bag of stupid.
Just rooting does nothing more than give you superuser access. It doesn't even do anything that uses the root specifically. Different roms do different things, but nothing to use battery...mostly they take things out rather than put things in.
Best thing to do is look at BetterBatteryStats and track partial wakelocks. That will tell you what is waking up your system and if there's anything spiking it, you can deal with it. Most of what really drains battery on this phone, other than bad apps, is somewhat random, and it will affect non-rooted phones just as much as rooted.
Must be something you did, picking a good rom make a big different. In my case. I flashed tweakstock to my daughter's phone since the first day it released (with tweakstock kernel), and never, I repeat never have any issue, when tweakstock 1.4 released, this is the second time I touch her phone and up until now she hasn't have any issue. If you use eclipse rom, PBJ kernel, Imonsey kernel, you're going to have issue. They are not bad roms or kernels, but they do have bugs. This is my experience.
Yeah, I think it's you. On stock, I'll be lucky to get 12 hours usage in a low signal environment. On a custom ROM, with custom kernel, I'll make it through the day. Of course, I've had a couple of random total crashes where I had to go at it again, but I deal with it.
PROTIP: the Facebook app needs to be told to stfu constantly. I would get an app like System so you can kill it easily-it still stays in RAM and in wakelock, taking clock cycles, even if you close it by backing out. I found that this was one of the best battery savers.

Yes, I agreed with kvswim, Facebook is a big battery drainer, I ended up using the browser for facebook, it's not as nice as the FB app, but once you get a hang of it. It's fine. I suggest if you want trouble free, ODIN pit file and original factory image, then upgrade to tweakstock with tweakstock kernel, then install Go launcher for smoothness. To save battery even more install battery saver by Antutu.(keep all default settings, don't play with it). You will see big improvement with both battery and smooth trouble free phone.

you really find a battery saver to be helpful. Every time i try one it ends up costing me more battery life than it saves.
As for the phone issues. Are you wiping data, cache, and dalvik before you flash? Not doing so can really muck things up. And a lot of times its just an annoying app that sucks up all ur juice, ie words with friends and facebook. I use them alot so I deal, but u can definitely tell the difference when u dont have those apps installed.
No i dont think its u...i have problems also.i jus made a post about my home/hard key...its always seems to b something after the next.but it looks like people find ways to deal and eventually conquer.also i appreciate wat the developers do.its alot of work and headaches.on top of posting and replying to many many people.its the roms that cause problems...constant tweaking and toying around...alot of times things jus need to b debugged a little it seems.but its all in the nature of what were all doing here.good luck to u

Hey. how about give the "battery saver" app by Antutu a try. This is one of the kind. It does not kill processes like others. It actually readjust cpu frequency during usage and put your phone in heavy deep sleep, after installed, let it run for 2 days, you will notice at least 3-4 hrs more during usage and 10+ if you let your phone sleep. I have test this app with wifi,4g,gps on 24/7 and I still have good battery life.
I downloaded betterbatterysaver to check my stats. Now to figure out how to read the data. Any suggestions? I've searched Google and it seems to be a mystery for many. It appears that Dolphin HD is using most, but I kill the program when I'm done???? I switched to mini and froze HD to troubleshooting. I only use FB browser too. I ditched the app long time ago.
Before I flash I wipe dalvik cache, data, and then wipe it again. I follow directions closely since I can't figure my way out if something goes wrong. I'm running tweakstock's latest right now and I'm really enjoying it. Very stable and snappy. However, the battery problem is killing the experience. It drained fro. 69% to dead in 6 hours overnight! Switched from 1.1 because the phone got very laggy and the hand off between 3-4g was getting dropped and I was losing data connection.
I will try the battery saver app. Just got battery calibrated and still not any better. My need to have a phone that doesn't suck will keep me playing with this thing until I get it right. My Charge is used so much it's like my third hand.

Did you try to disable(freeze) SDM app and also Google service? May need to backup all your apps and do a factory/data reset, If not help, possible to re ODIN factory image (see pos # 5) since you have data drop issue. Some thing is mess up in your OS.
For betterbatterystats look at wakelock and see what process used the most.
If it died overnight then something is definitely eating your battery. Are you in a low signal environment? Go to settings, about phone, then battery usage. If anything besides display is taking more than around 5-10% (can be more if you use it a lot) then that's your main problem. If your cell standby is more than 25% it's the low signal that's killing the battery.

Data is up and running smooth after flashing newest tweakstock. My home has a strong signal and my bedroom is sometimes 4G so I don't believe the signal was low, unless the transition between radios killed it. However, it wasn't a problem 3 weeks ago.
I did freeze SDM and noticed some improvement. Buhohitr, did you mean freeze Google services framework?
Battery usage seems to be normal for now. I am noticing Dolphin is no Singer sucking down 35% or more since I switched to Mini. It doesn't even show up on the list.
I'll see how it goes today and report back on wakelocks. If it doesn't get any Beyer ima Odin to stock and root/flash tweakstock again.
Also, the battery doesn't drain unusually fast wile in use, browsing, music, etc. But when it sits it drains at 3-4% an hour.
I would try manually calibrating your battery. It really worked for me. On average I get about 18-19 hours on one charge with medium to heavy data usage throughout the day. There is a thread in the General section.. I'll post a link in a little bit.

Wiping battery stats is a complete placebo. All the battery stats stores is the state of apps as related to various things that affect battery life (like display on time, screen brightness over time, and wakelock states). It does nothing that will actually affect your battery life one iota. It is actually cleared every time you charge your battery to 100%, so manually wiping it is completely pointless.

I'm well aware of the post of Dianne Hackborn debunking the myth of wiping the battery stats; however, if you actually read the post on the steps to calibrating your battery, it's not just wiping your battery stats. There's actually a few more steps involved. You're right though, if you just wipe the battery stats and expect better battery life you're just wasting your time.

To disable Google Service, go to settings -> location&security and uncheck Google service. Do not freeze Google framework. Also seems like your phone is not in deep sleep, please install "battery saver" by Antutu and let it works for 24 hrs, you should see huge different when your phone is sleeping. BTW what kernel are you using? If you're using PBJ kernel you can install "CPU tuner" to further keep your phone in deep sleep. I'm talking about 1% for 3 hrs sleeping.
I'm curious as to what Battery Saver actually does. The app's market page doesn't say. I'd be curious if it would interfere with my IMAP push email or SetCPU's overclock settings.

I've done that and never seen an actual difference. Like I said before, I have no reason to believe that any of it is anything other than placebo. My normal daily variability in use is more than enough to account for any perceived differences. On top of it all, bump charging is not good for a Li-Ion battery, so if anything, those instructions are a good example of how to lose long-term battery life for short term gain.

Personally, I believe that most of the time the procedure does nothing. I think there are times, though, that corrupt data gets into the battery stats. For instance, I had an app lock up my phone and force a hard boot. When the phone came back up, it showed 22% more battery than it had previously. I believe that bad data such as this can over time affect how Android reads your battery life. In that instance, I believe clearing battery stats would help. I don't think doing it just because a new ROM was flashed actually does anything, though.
Background: I have had phone 11 months. I am very familiar with how the battery drain is while it is stock (WiFi ON all the time). battery lasted ~16h which is plenty for me.
Rooted phone, Battery Life on AR14 and IceColdSandwich (and others) was around 20h with WiFi on all the time and light use.
Recent Kernels (anything IceColdSandwich 3.0.0+ or AR 23+ (haven't tested between 14 and 23) cause a base of around 50mA of drain even when phone is locked. Battery life is ~8-10hours WITH NO USE. I have tried these ROMs without installing ANYTHING on them with the same results.
Current Widget does not identify an offending program from what I can tell.
WiFi off, the phone lasted 2d9hr of pretty light use.
I first started looking into WiFi when I forgot to turn off airdroid and unplugged the phone for 3 hours. I found AirDroid still running but could not connect to it via laptop or desktop until I tinkered with the phone a bit more and the WiFi connection cycled.
However during this time, the charge lost on the battery was a reasonable rate, and after the WiFi connection cycled it dropped like the usual rock.
What I've tried:
WiFix
WiFi polling interval increase
Cleaning/checking battery cover contacts
Changing battery covers
Battery Calibration (which is a myth from other reading I've done)
A couple of different programs like Juice Defender.
On the list to do:
Try a different Kernel
Root my friend's phone and trade him hardware (he says he never uses WiFi, so it won't be an issue for him)
/wrists
Thanks for all the suggestions and help so far. I understand that the problem is pretty obscure and seems rare.
on icecoldsandwich ive seen quite a few people show an improved battery draining using lordmods newer bfs kernel. maybe give that a try and report back?

btw, very good informative question. its heart warming usually we get 'my battery sucks yo, fix it!' haha
Here is some irony.
Exitz ICS AR25 has been on the phone for a couple of days and has lost essentially 10% per hour when not on the charger (been off work in my house) After the 4th day, I installed AirDroid and AngelCamera. I took it off the charger last night...
92% 6 hours later AND the phone has been awake(?) all night...
Seems I left AirDroid 'running' but couldn't connect to the phone through AirDroid until after the WiFi cycled...
I will see how the drain is today. I'll out of the house all day tomorrow (half a day in Denver), toggle off the wifi for a day at home, and then try your suggestion Darunion.
Here are a few screen shots (first two are old), and honestly, I don't know how much I trust the battery stats.
IceColdSandwich 2.0.0 pretty much shows that battery life I have been used to for a long time including before rooting. Not AMAZING, but not fail. (WTF Proximity Recaibrator 29% of Drain on a 16 hour day?) Also note this is about the same rate of drain I experienced with Existz AR14 last week. Light use and ~16-19 hours of battery life. Not amazing, but I can live with it.
IceColdSandwich 3.0.0 pretty much shows the battery life I have been getting with any ICS roms since.. well 3.0.0 was released. Oh and the voice call that is 37% of drain lasted less than 10 minutes.
Existz AR25 (someofthedrain.png) the steep drop was a 20 minute phone call...
And Finally Airdroidwtf.png is the same install three nights later (this morning) If I could get battery drain like THIS on a regular basis...
Anyway, I'll keep trying to isolate this down to the specific 'area' of the phone that is causing it....
Edit: and as for Darunion commenting about the information I've included... I'm a patient person, I don't want to be a drain on the community, and I have no issue trying to solve a ROM, APP, Radio, RIL, Or watever issue. I'm only posting because the issue isn't unique to a ROM but is unique to a time frame AND the issue is not solveable via Google or XDA search
Right now it is looking like the 'extra' drain on newer ROMs is directly related to the wireless being on*.
Right now the phone is at 1day 19 hours with 14% left and the wireless was only on for the first couple of hours this charge cycle.
I never thought there would be such a considerable difference between battery usage on any ROMs.
I'm going to continue looking around and trying to solve things, and I haven't quite made it to trying the Kernel, Darunion. It is on the list after I toggle WIFI on and off throughout a day.
*The rest of this post is just back-story I have ran the phone on stock for 11 months before rooting it and during that time, I got used to leaving the WIFI running all the time simply because the battery always lasted through my longer days and my-typical light-use. I'm near WIFI that my phone connects to about 80% of the time.
So after rooting, I had a little increase in battery life and I never changed this habbit, or more to the point, I was leaving WIFI on as to make it one less variable in drain while testing various ROMs and different build dates.

I was on battery for around 13 hours yesterday with wifi on for at least 8 hours of that and plugged my phone in with 51% battery remaining.

Yeah, I know this isn't a typical issue for most everyone, and am not implying so.
Likely it will end up being something very specific to the two WIFI networks I am at for 80% of the time OR something else that is very specific to my circumstances.

Have you, by chance, removed and reinstalled your back covers? I know it's unlikely, but since they contain the antennae, maybe they've come a little loos, resulting in higher imepedence connections.

I have not specifically toyed with the covers as part of trouble shooting. I will be sure that I look at them after my battery finishes charging on WIFI.
It does seem to be more a software difference, (I've casually be at this for the better part of 2 months) as I have seen expected performance when flashing back to a ROM I've used.
Thanks, I like being able to limit variables and this will be one I check before charging the phone again.
(What I'd really love to do is convince my brother or one of two friends who have the Inspire 4g to let me root their phones so I can trade them phones for a week and really isolate out hardware issues
fyi if you are still running icecoldsandwich. 6.2 just was released. Maybe give that a try?

Right now, I'd like to figure out WHY my WiFi is so bad on battery drain with later AOKP releases.
I'll try to rule out hardware issues (I'll look into antenna and MAYBE convince a friend to let me root their phone and trade them for a week... if not then covers at least.)
But likely this is something about newer releases and how my WIFI is setup. I don't live in a high-density area, so it's not because of too much wifi trafficz (I can barely see a 2nd wifi with any device and it's on the opposite end of the frequency choices.... by my settings)
Anyway, I am a very patient person, so I'll continue working on this slowly so that I can be thorough and find the real cause of the problem.
What I would wish is for someone to point me in the direction as to how WiFi MIGHT drain the battery so hard for later releases but not earlier. I'll be reading up more on logcat and how to read it in regards to wifi... but searching and reading is hard because 'wireless' and what not are very vague terms
Now at 1% (still) and 2d9h... is MORE than double my record on the first roms I tried after rooting OR my stock rom. and MORE than quadruple my record on any of the newer roms
I've swapped battery covers with a friend this past weekend, and the WiFi being on still drains the phone considerably (~8%/hr) when turned on. So if it's a hardware issue, it's not in the battery cover.
Wifi and blue tooth are very hard on the battery regardless. But 8% an hour seems pretty steep tho.
I would start by getting the current widget in Google market and put in on your home screen to monitor your Mili-volt ussage. If its running high like the 200+ constantly you have a lot of drain going on. When in sleep mode it should drop down to 0mv up to 8mv. If it stays high in the sleep mode you have apps waking your phone from sleeping. Which causes tremendous drain.
Next I'd try removing apps that have wifi permissions. To see if that drops your mv ussage.
Drop your notifications to less frequent times on your email and Facebook.
Remove any task managers or juice defender. They run constantly.
Google + is a massive battery drainer. Remove or limit notifications and sync as much as possible.
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.
Last but not least get a toggle button widget for wifi and turn it off when not using.
I'd you follow these steps this will drasticly decrease your battery drain.

Thanks for taking the time for this response!
I started by running current widget for about a week and with a 3 different roms AR23(?), IceColdSandwich 2.0.0, IceColdSandwich 3.0.0.
I was stock for 11 months, and ICS2.0.0 was a little better than battery drain than stock. AR23 and ICS3.0.0 were terrible and pretty much ran a constant 50ma drain asleep or awake as a baseline.
I'd really like to figure out what the difference is with the older AOKP and the newer AOKP, but that may never happen.

I've been testing with stock roms since a couple weeks before I posted this thread. This is because current widget didn't really show any specific program causing the issue, so I wanted to make sure that I didn't have some issue from my installed programs.
The most I've installed (out of necessity is AirDroid and AngelCamera) in the past few weeks. Both were installed when I ran without wifi on one charge for 2d9hrs.
(I don't have a google+ account, I don't have juice defender or any task managers aside from the stock rom)
Also running wifi fix apk could also help. If you are knowledgeable enough you could also edit the build.prop to set the wife scan at a less frequent rate as well.

This is likely going to have to be my solution. Just run cell data all the time unless I am doing something specific like downloading files or uploading pictures.
OR
Maybe I can convince my friend to let me trade him phones (root his and nand backup and then restore all his stuff to my phone) and see if it is about the same drain. His phone was bought a couple months after mine AND from a different vendor, so it isn't going to be out of the same manufacturer's lot.

Thanks again. I'll definitely try the wifix along with the rest of your suggestions that apply
I'm in the same boat you are. I'm running ics aospX ar-26 and I can barely get mine to last from 8 til 4. Wifi is pretty prevelent around here and I leave it on most of time. I guess I could try turning it off til I need it. Anyway I'll be following this thread.

You also might consider reading the threads on calibrating battery after flashing roms. I made the mistake of flashing a rom @ 40% battery. It jacked my stats all up. The new rom thought 40% battery was actually 100%. It had my stats all screwed up too. Except mine was Bluetooth. Showed running at 60% of battery ussage. So don't trust that system tool. Because the display is almost alway gonna be the biggest drain on the battery. An app called "spare parts" is a little more accurate.
I ran the gambit on this one finnally got my battery back to normal for me anyway. I've never seen a full days use with out charging. Get about 14 hours Max now. But the calibration steps is the way to go.

I actually have read quite a bit about battery calibration... and before I flashed a new ROM, I've made sure that current widget has been tracking 0ma for a while. (Only reliable way to be sure you have a full battery from what I can tell)
The batterystats.bin file and calibration has been ... contended in a number of places, mostly stating that when taken off the charger 'full' the battery stats file is overwritten... which makes calibration a non-issue (assuming that you occasionally charge your phone for a while after it hits 100% from time to time)
The problem is that the WiFi mA draw is HUGE compared to what it should be (in theory from reading other people's logs), and it's not because of the battery cover. AND It's not as bad in older AOKP ROMs than it is in newer ones. SO it could be a hardware issue exacerbated by a change in how WiFi is handled, but the hardware issue was never noticed because the battery life Stock was sufficient for my needs.
I've been busy working so I haven't been able to continue troubleshooting the phone (damn my patience), but Mondayish, I'll likely have traded my phone with a friend and root it and flash a new rom and see how the drain is with completely different hardware from a different vendor from a different lot of phones.
I had a similar issue with wifi. I changed the build.props wifi supliment scan from every 15 seconds to 180 and used the wifi fix manager apk. That seemed to help. Coupled with a proper battery calibration and I'm back to my display being the major battery draw.
So don't know if that helps but it seemed to work out my bugs.

This I can do right now.. and given I'm on the same, unmodified AR24 release, I can observe it for the weekend before I annoy my friend about his phone.
Seems the WiFi scan interval was already set to 100... moved it to 180 anyway.
I used to have this issue. I could literally see my battery draining while I was using it. I keep wifi on most of the time. I recently purchased an anker battery online. It is AMAZING! My old battery wouldn't last more than 6 hours or so. Right now I'm at about 14 hours on this charge, and I'm at 47 percent. Try swapping his battery for yours for a day or two. Another thing to try is different radios if you're losing power to cell standby.

The phone ran for 2days 9hours with WiFi off and lasts for 8-10 hours with WiFi on. I am pretty sure that it's not a Radio/RIL or a Battery capacity issue. ;(
Hi, so I recently got an Infuse from someone that is still on Froyo and I figure I might as well upgrade to a custom rom.
Since I care about battery life the most, I figure I would ask which version of Android provides the best battery life for the Samsung Infuse: Gingerbread or Ice Cream Sandwich.
I probably won't be running apps that fetch/push for data a whole lot, which obviously helps the battery life. But I thought I'd ask to get someone's opinion on this specific phone and a comparison between Gingerbread vs ICS before picking a rom.
And the winner is... Gingerbread!

Gingerbread is a better battery saver. Although i get decent battery on ics and jellybean. I know i perfer all that ics/jb has to offer in features over having battery life. But for what your asking id suggest AEON or the stock gb. Aeon is very stable and has some cool extras without much battery drain

I have never payed that much attention to battery life..
usually lasts all day for me on JB, that's all I need
Sent from my sweet & buttery Infuse
the more recent ics and jelly bean kernels get great battery life due to fixed bt and wifi drivers (the wifi driver and binary were taken from another device from what i understand) and more stable cpu clock code than it had initially. not too much more than stock but i have to say it is better for me. but i guess it all depends on usage. one may have better standby vs awake battery life or something. the available kernels have been this way for atleast a month. when we start to see more kernels with undervolt it should get better yet.
I'm using CM10 8/23 and my battery life is good.
One of the best I even made a snapshot (can't upload right now): 51% left after 12 hours 46 minutes.
That's why I'm in a dilemma between jelly bean and gingerbread. I do appreciate JB a lot, way better functions. But still the battery life and compatibility are big issues. I can get 2 days under gb but only less than 12 hours in JB, that's a big issue.
I have been getting great battery life with the latest JB ROMs I have been using. Pretty much on par with the GB ROMs I used.

Can't say i've had good luck with battery life, I used to average 3 hours of screen on time in Gingerbread, but since moving to ics/jb that has dropped to anywhere from 30 mins (if i leave the phone and standby drain eats it) to 1 hour 45 mins on a single charge...not good.
No rogue apps, no media scanner (i constantly check these things with betterbatterystats, i don't install anything i didn't install on gingerbread). Just the cell phone standby drain eating my battery alive (BBS reports it as GTALK_ASYNC and RILJ wakelocks).
I've been researching it for months now and get various answers (the wakelocks are caused by bad APN settings for example), tried all the fixes, still no luck. I suspect that it's probably a Rogers thing but who knows.

you may consider a factory reset and sdcard format
when you reinstall, decline all google locations and backup services.

I have done a factory reset, i formatted my sd card not too long ago (I also suspected this)
I also make sure google locations is disabled, never keep backup enabled (i did once by mistake and the auto restore nearly killed all my monthly data)
I am going to toggle wifi tonight and set a marker in BBS, i'll check the drain overnight (I did this a while ago and it did improve standby drain somewhat, but I am going to try it again)

I've been playing around a bit with different gb kernels, odex and deodex.
I found the drain issue much less on stock uclb3 kernel and rfs file system.
Almost all drain were associated with being on wifi...wakelocks and something else kills the battery.
If I have wifi off, there is usually not any issue.
You may have to play around a bit to see. My experience on cm9 and cm10 has been limited. I have noted several users noticing drain on cm9 and cm10 as well.
To avoid drain:
1. Use it to the max and constantly.
2. Leave the phone on airplane mode when not in use.
3. Turn off data (wifi and mobile data) and background data when not in use. I use this last mode.
Thanks for the tips man :good:
Airplane mode of course makes batt life better (disabling data doesn't), but when I start having to make sacrifices I didn't have to on GB it becomes a problem for me. Why should I jump through hoops and gimp my convenience for battery life that still isn't even as good as GB?
Instead of that i'd rather try to find the root cause of the problem. Doing so then allows us to help others that may have the same problem.
It definitely is an issue with the radio (or rather CM code overlooking something concerning the radio). What exactly, i'm not too sure. I've tried different modems as well, UCLB3 on JB was awful for battery life, UCKL2 and UXKG3 are slightly better but still not that great.
I don't want to complain about these things, I always try to research first, but damn....i'm stumped.

Yeah, I agree with you there. The techniques I use is pretty simple. Pose the hypothesis. Start with a full deck and slowly eliminate or start minimal and add.
ex: flash jb without gapps; without microSd. try different modem; try a different kernel. different kernel from different build.
have to use it for a few days to find out.
do the same for cm9.
add gapps...
add microsd
etc..
at some point, you will find out contributing factors.
There are a few battery thread that may be helpful if you havent looked:
