I'm having the strangest problem with my HTC Evo...
I used to get over 22hrs of moderate use (rooted) and ever since flashing any ROM running Sense 3.0 my battery life is affected to the point I'm lucky to get 6 hours of use. It discharges 15% within the first 10 minutes after unplugging the charger and continues to discharge at an increased rate throughout the day.
I unrooted the phone and took it to Sprint to "test" and after 3 hours they gave me back the same exact phone claiming they had "updated" it and everything, including the battery, had tested perfectly fine.
I feel like they are giving me the run around because obviously something is wrong here.
Any ideas as to what is going on here?
Rooting doesn't improve battery life, never did. Think of rooting as gaining admin privileges to a Windows PC, for example.
I think you have a background process running that is taking up a lot of battery, check the Battery Use page or reboot the phone.
I know, but it shouldn't diminish it either. It does gives you a chance to see a potential increase by undervolting, underclocking, ect.
Anways, no background apps running. All display scaled down, GPS off, ect, ect.
I have no clue as to why this sudden decrease in life. And Sprint says the battery is testing "excellent" as is the phone. Obviously something is not right here. Feels like they are being lazy and trying to avoid giving me a replacement.
Evo is known for bad battery usage. Best thing for you to do is get a backup battery.
Lol. I know that too, I'm not new to the Evo. I work with phones, Evo included, on a daily basis at my place of employment.
I'm saying this same battery used to last over 22 hours with moderate use when the phone was rooted and underclocked. Now the phone drains the battery amost instantly.
I refuse to purchase an additional battery to combat a problem Sprint should be fixing. I paid over $500 for this phone and haven't even had it a whole year yet. Something else is going on here...
Sounds like a rom issue, not a hardware one. Those sense 3.0 features and eye candy come at a cost.
Yeah. Sense 3.0 is a battery hog. Try cm7 or something AOSP
ADR6300
yeah, one turne off and reboot, Battery Life TERRIBLE too, i'm lost 10% when reboot

It's ture ！
Have you tried an app that shows you battery usage over your running apps? May tell you which programs are stealing all the juice
!. Rooting does not have anything to do with battery life...well..not directly..it depends on your kernels, apps, phone settings, etc.
2. I agree, Sense 3.0 seems to drain your battery a bit more than previous Senses... well...you know what they say, beauty has its price..about the AOSPs, they have better battery live but they are not so pretty as the Senses...again...beauty has its price
If it helps the 'Live wallpapers' are known to eat battery, but what it could be is Wifi, if you leave it switched on all the time it may be connecting to open wifi networks without you realising and eating the battery.
Interestingly though, a whole day of use, some wifi a bit of camera and some calls on a wildfire with wifi on, didn't seem to drop the battery much and this is with a rooted phone.
you can try green power
Even though it may sound lame to some of you, the app Juice Defender has actually helped extending the life on battery quite nicely for me...
Another possible route might be to try different Radio/RIL combinations, some can also extend your battery life.
Not to forget, as someone posted previously things like live wallpapers or background process. Task Killers have been known to cause battery drain for instance.
Good luck in your quest for battery life!
Hans
if you go to battery use in settings, youd probably find out whats causing your battery drain

Is there a tweak out there that stops the stupid battery from guzzling? Im tired of charing it constantly and I swear it takes hours and hours to charge it back to full power. The thing cant last longer than a day without loosing power I cant stand it. Whats making it use all that power? I thought maybe if I switch wireless it would help but I didnt notice a difference.
I can get 2 days out of my battery.
I let it drain to 1% and then stick it on charge over night. When i get up the battery will be at 100% and then 30 minutes later down to 90% but it settles down after that.
I do not have wifi and bluetooth on all the time, just when I need to.

I don't understand people telling battery lost for 2 days..... even if we keep phone idle it will lose power in 24 hrs i believe....try like this try to use ROM with out manila & with manila once you will know the difference other than that there is some tips to save battery in Energy ROM thread in 3 rd 0r 4th post ..
4 days normal usage.
Manila2, GSM
15 minutes call, 6~10 text message, sync exchange, 30 minute ebook reading per day
If I build rom myself from the kitchen. It usually runs for 2-3 days.
However, in most cases when I try decent cooked ROM, for example, Energy - battery drains in about 5 hours. That's been the case with other cooked roms as well.
I suspect that some popular configuration change done by cooks causes battery to drain in certain environments. Would be nice to find out which change is that.
Processes and services often place a strain on the life of the battery; add to the mix a buggy service or application that further shortens battery life and one has an unusable device.
Another habit that can shorten Li-ON battery life is full discharges - near 0%. One of the members put out a thread a while back on research he/she had done on batteries - worth the read if you haven't already.
Cheers,

I just had the same experience, cooked for the first time and my battery was better than it has ever been!
Since then I have flashed to RRE 21731 6.3 and it seems my battery has stayed the same (Brilliant, 2 Days no problem).
The only thing ive done differently is I have used the new UK Voda rom as my Stock Rom that i flash before flashing custom, and i believe this may have something to do with it...What, I don't Know.
I also believe changing the Radio After a flash can affect battery life, I always try to flash a new radio before a Custom rom.
I have wondered for some time wether the European Touch Pro is slightly different to the US Fuze in its hardware, Since most Cooked Roms are configured for the Fuze maybe that is what it is?
maybe we will find out..One Day
turn off 3G and you will get much better battery.
Get a Blackberry Bold. My phone has been on for 2 days, sent around 150 texts, got in 150, I'm at 85%

That will ****-up your battery, you should never let it drain to 1%, just charge it when you have the time, preferably before it drains to about 20%.
I guess it all depends on the eye of the beholder, I come from the Diamond part of XDA, and we are lucky to get 24 hours on the Diam.
I was happpyyyyy with my new TP battery life -compared to Diam that is-
But ya, turning of 3g and being picky about processes and back light helps.
Greets to all.
Search the development and Hacking thread for Windows Long Life/save your gonads. Chainfire is developing a neat application to automatically switch from 3G when not needed. I tried an early version and it seemed to significantly increase my battery life.
Check my sig....it tells you how to deal with Li-ion batteries...

Check out chapter 17. I cover this pretty thoroughly.

An app that may help is Advanced Task manager, it has a widget to end all running processes/tasks which i tap before putting mine to sleep about 1000+ times a day it seems. go in and exclude ones you may want to exclude always and then its as simple as 1 click. as everyone else said, no gps,wifi,3g when not 100% necessary. also, get widget "toggle disply" from rounded labs and keep your screen completely dim (not like you can't see it...), being able to make it bright when you step outdoors. Also, toggle backlight app for root users keeps the pesky keyboard backlight off when you don't want it on (suggest making keyboard shortcut for quick toggle). last but not least because i'm sure theres plenty more, but yesterday i switched to cyanogen's newest stable ROM and it seems to be much more effective than any other i have tried in the means of saving battery life. had wifi on after a 98% charge for about an hour and a half (30mn usage) and it only went down to 91%... wow. "and that's all, i have to say, about tha-aat"- Forrest Gump
Firstly I don't think this is the right sub-forum for this question since it's not a specific ROM question.
Secondly, try nueDynamicClock, if you use the right settings, you'll extend your batt life by at least 1/2 a day if not more.

It's really very simple. Flash an awesome rom, and the battery burns and burns. Flash a rom you hate, and the battery lasts forever. Don't over-think it.
hi guys.
i was eager to start up this discussion and am glad to find it here itself.
even am really finiky about battery.
tried alot of thing but cudnt find any spcl tweaks.
though i came across some registries from advanced config and other wise also but they seem to be more worse.
;IMPROVE BATTERY PERFORMANCE
[HKEY_LOCAL_MACHINE\Comm\AsyncMac1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\Irsir1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\PPTP1\Parms]
“DisablePowerManagement”=dword:0
[HKEY_LOCAL_MACHINE\Comm\L2TP1\Parms]
“DisablePowerManagement”=dword:0
when i use these tweaks the power consumption of my rom reached to 4.112 volts(as per power detect) which otherwise without these tweaks is 3.992 at startup.
more power consumption i guess means less battery i guess.
and even if its not still these tweaks as per my usage show bad results.
why so?
and arnt there spcl application which can detect the packages which might consume more battery, as i have over 50 packages in my rom and it'll hell to check which eats more.
Some tweaks I do
I have also found for me that disabling these things in advanced config also helps.
Performances
> File System cache: Disabled
> File System filter cache: Disabled
> Glyph Cache: 32kb (advised) I'm not sure if disabling this one is a good idea. I like having a little bit of glyph cache on my device.
Light senor
> Light sensor polling: Disabled.
*Note: If you want to still have light sensor on (this means the auto backlight feature) I would set the:
> Light sensor polling interval: 2000. This will make it poll every 2 seconds instead of every .2 seconds. I would even try setting it to 5000.
The backlight will make a huge difference on how long you battery will last. The brighter it is the more the battery needs to light up that screen. If you turn off the polling all together it will make the battery last longer.
Also running fancy UI apps will also deplete the battery more. Just common sense really as another poster alluded to earlier. The more things you have running and sucking up memory the more battery it will consume. If you disable TF3D or other apps such as this you will get your battery to last longer. Given that these devices are meant to have these types of programs on them you will have to weigh the options of how much you really want to "tone down" your devices to get the most out of your battery.
Also different radios will cause you battery to last longer. I suggest to everybody that they try different radios to see which ones last longer. Also people who live on the edge of 3G and EDGE area will cause the battery to drain faster as it constantly switches in and out of 3G coverage.
WMLongLife is a great app if you don't need 3G while you phone is just sitting in you pocket. It works great for me and when I want to use 3G I simply launch opera and the program will automatically enable 3G once again.
There are many things that you can do to improve your battery life. I encourage everybody to find what is best for them given what they use there device for and try and test things out. The best way to tell which works best for you is to simply try it out for yourself.
**NOTE** I also set all ROMs that I flash with a page pool of 0. I don't know if this has any real effect on battery life but it does seem to make my battery last a little bit longer. Not sure if this is a placebo affect though.
Took a look at my battery just now and I'm at 70% and the phone has been unplugged for 15+ hrs (I'll include a screenshot). Because of this, I thought I'd share my setup just incase it could benefit someone. This isn't a fluke, I've been experiencing this with the rom/kernel/modem combination for over a week now and I'm hesitant to change roms .
I will say there is nothing different about my battery life while using the phone heavily and that's to be expected. Like yesterday I was on my phone ALL day and the battery lasted about 10hrs (few phone calls, gmail push, HEAVY data use, low reception area for a while, GPS Navigation multiple times). The biggest gain comes from idle time. I use my phone pretty much like everyone else, may take a few calls, normal gmail push, data for streaming vids, twitter, fb... things of that nature. With other roms I've had up to 40% of my battery drain overnight while doing nothing! But with my current setup, I've gone about 36hrs (once again with normal to light use) without plugging the phone up. My setup is as follows:
AT&T Samsung Captivate
ROM: Phoenix 1.0
Kernel: Supercurio's stock + voodoo captivate kernel (Voodoo disabled)
Modem: I897UCJJ4
Theme: Custom concoction put together by me
Now I say I'm hesitant to switch roms, but to tell you the truth I really have no choice lol. I have a release date model Captivate and any non Captivate modems cause me to loose signal randomly therefore I must stick with Captivate roms. As sucky as that may be, I must say I'm not disappointed in this roms performance.
O, one other big thing I've found is that your launcher plays a CRUCIAL role in battery consumption. I've gotten the best life using Zune Home. The dev of that has two programs, Zune Home and Faded home. Zune Home is the one I used. It's very basic and some may not like it. I currently am using Open Home as my launcher and the battery life with it is great as well.
Well I thought I'd share this info just incase it could benefit someone out there. If this is the wrong section please don't hesitate to move it.
That's a beautiful thing. I'm sure lots of people are jealous! Luckily, I haven't had to much of a battery issue. I'm on Serendipity 2.0 and with heavy usage I last HOURS.
Not a big fan of either launcher and that does play a huge role. My launcher usually usually runs about 23-28MBs in the task along with Widget Locker which is about 5-9MBs.
Here are the settings I'm running on CM7 to get amazingly bananas battery life (with the display being on for about 5 hours!)..
1. Conservative governor: 245mhz - 1017mhz in CM7 settings
2. Install the 'BatteryCalibration' app from the market. This app caused the single biggest improvement for me after having flashed so many roms and never calibrating the battery. If you've calibrated it before though, I don't think it'll be very useful for you.
3. Install 'NoBars' from the market to automatically turn on airplane mode when you have no service. (This might be useless to some of you if you always have a signal; Very useful in NYC subway though)
4. Use a 2G toggle widget to have the phone only use the Edge connection when you only need it to receive calls/ texts and don't need the high speeds. I use the toggle widget in the CM7 notification bar. HUGE battery saver.
Give these a shot and let us know how they work for you
I've reached the end of my day and here are my final stats..
Mmy display has been on on over 5 hours now and I have 5% of the battery left. Seems more than good enough for me. Hopefully it will be for some of you too
Edit - Updated with more recent stats

Question: It's cool that your display was on for 3 hours, but what did you do as far as app usage??
If you did use your phone "a heck of a lot" wouldn't some apps like "internet" "maps" or something show up on the battery use %'s???
For example, currently, other than phone idle, cell standby, voice calls and android, there's also internet, mail, maps, and other apps that I used today alot.
Good observation. I have no idea how android chooses which apps to show on there, but I think it depends on the ROM? I remember on Iced Glacier cell standby would barely use 5% of the battery and on CM7 it uses >40% consistently. Idk.
Maybe what those apps used up here was nothing compared to the display, wifi and phone idle time.. Just a guess.. But I did use the browser and xda app and listened to music via the Rdio app running in the background several times throughout the day, and sent multiple texts and have had my wifi on for about 5 hours now. I can't really find a menu that would show these statistics except in the Spare Parts app, and here you go..
I got 17 hours just yesterday with 9% left with moderate to heavy use (texting, web browsing and ps1 emulation).
I didn't do anything besides use faux's kernel with the smartass govenor. I have the max speed overclocked to 1.8 as well...
Nice. I just got over flashing new kernels for a while since the stock CM7 one has everything functioning perfectly and new kernels would improve on something but mess up something else in my experience.
I can't seem to find a 2g toggle widget that works with Royal Glacier. (one touch, I've found a few that take you to settings) When I was running Royal Ginger I would always use the one that came in the notification bar.
Wifi status is also a good app to remind the forgetful to turn off wifi when they leave the Area.

This is GREAT battery life... i wonder what word i'd use to describe mine.
i Pulled my Phone off the Charger this morning @ 7:20pm EST. Now it is 3:13 EST. and i've got ~50% left. So thats what like. 7 hours
neidlinger tap that 'screen on' tab and lets see how long your screen was actually on for?
Either way congrats, and it's good to see ppl are over the battery issues.

since my last boot. 8:10AM when i loaded the new CM7. 1h 1m 59s.
Unless I'm missing something, the 'BatteryCalibration' app won't increase your battery life. It will just help to get a more accurate reading of your battery level.
I've played around with different roms and kernels. And yes, they do have a small effect on battery life, but not all that much.
Here's my tip for battery life. Get on ebay and buy one the of the cheap packages from Hong Kong with 3 batteries and a standalone charger. Like this:
http://cgi.ebay.com/3x-New-1500mAh-Battery-Charger-HTC-Mytouch-4G-Merge-/290556738794?pt=PDA_Accessories&hash=item43a687fcea
I bought a similar package a few months ago and now I never have battery problems. Nor do I have to take a chance on wearing out my micro-usb jack like I've seen happen on a lot of other phones.
Maybe. All I know is my battery increased dramatically after running that app once.
I measure battery life by how many hours I am able to keep my display on before it dies rather than how long after it comes off the charger (like nedilinger does). My battery used to die after about 3 hours of the display being on. Now it consistently lasts 5 hours.
Anyway, I was just trying to let others know what I did to get a really good battery life on my phone thinking it might be helpful. Apparently that's not appreciated. Thanks tho.

How long does 1 of those batteries last?
Sent from my HTC Glacier using XDA App
simple way to get awesome battery life without any extra steps is to install RoyalGlacier 1.6, that's all. A couple days ago I ran my phone for one and a half days before charging it again, and it still had 14% battery left. RG is pretty much a polished version of CM7, runs blazing fast and smooth.

Better than what's reported under CM7. The battery life I posted above was on RG.
you say you don't sacrifice 4g but you admit you have a 2g/edge widget?
To me "not sacrificing 4g" means not ever turning it off, maybe i'm mistaken
I had battery issues, I'd have to charge it mid day else it would die. Juicedefender helped a bit (claimed to do 1.7x battery life) but I uninstalled it, rooted the phone, and uninstalled a bunch of stock apps
For some reason now my battery lasts a very very long time, don't know how or why that is. I also admit I don't use it as heavily as some people, but my habits have not changed and I did have to charge it mid day (like i said) even with little usage

Obviously, it's hard to say without describing how I use my phone, but I get probably 10-15 hours of medium-high usage. I probably get about 4-5 hours of talk time. I'd say the Chinese ebay batteries probably last 80-90% as long as the OEM battery. Quite decent considering the price.
My earlier thoughts about the BatteryCalibration app could be wrong. I don't really know all the details about how Android battery calibration works. I just assumed that it simply learns about all the bad spots in your battery so that your phone doesn't instantly jump from 80% to 30%. I also assumed that the phone would die when the battery had no power left, as opposed to when it says 0%, but maybe that's not the case. Regardless, if it helps you, more power to you and I appreciate you sharing the app. I didn't mean to come off as an unappreciative ****. If I did, sorry bout that.
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?
http://forum.xda-developers.com/showthread.php?t=1450962
kernel: http://goo.gl/ZqBZl
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'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. ;(
i installed on my infuse the rom: "RemICS-UX_INFUSE_I997_build_1.1_.5" but after that, my battery stopped having good lengthis, it discharged quickly ...
I want to know what the failure of the rom, if you have one, or I should I do
so that the battery lasts a timely manner -
thanks
It's just one of the prices you have to pay for ics...

You could try and use voltage control to lower the CPU speed and stop as much push notification and things like that.. use airplane mode during the night...
Just some random options...

Ive said this numerous times, but doesnt seem to be taken into consideration.. Your battery life is what you make it. Meaning, its up to you to get the most out of your battery life. I have mine undervolted (hardcore style), animations off, auto brightness, gps/location off, wifi off unless downloading very large files, plenty of other tiny settings that add up to some extra juice. I normally get a day to a day and a half until i die...
Im not trying to be a d***, but it seems frustrating that everyone worries about battery life and for many that is their ultimate decision making factor.. Lets say your battery life only last 12 hours.. Lets be honest with ourselves, the average person works 8 - 9 hours and then is free to do whatever.. Most of the time personally for me that turns out to be relaxing and watching tv so i charge my phone then. I guess what im saying, is are you really gone that much that you never have a chance to charge your phone?
