Since I had the phone, battery drain has been ridiculous. Around ten to fifteen percent per hour. After recently switching to humble 1.5 my drain is nearly 30% an hour. I will try to recalibrate soon but should I consider getting another battery? I was listening to mp3s and checking email during that hour and about ten minute of gps. But the drain still feels a bit excessive. What do you think?

What kind of signal do you have? Under battery use, is there anything that's been using a disproportionate amount of battery? What do you keep on as far as services and connections, like GPS, 4G, etc?
My signal is usually fine with 4g a majority of the day. It was struggling a bit today in the underground and I had to turn off and on the data to get a solid connection a few times. I usually keep on the data and gps or bluetooth on depending on the situation. Usually just a combination of those. Data is the only one on all day. Nothing looks unusual under the battery usage except for the display using 82%, but it was like that on stick as well.

Well, 4G and GPS together can use power pretty aggressively. Granted, 30% an hour seems excessive and may be caused by something else.
A couple things you could try - force 3G (you can do this manually or via a downloadable widget I believe) instead of 4G and use location services instead of GPS (unless you just need GPS). I know these aren't as "attractive", but can provide similar services with less power consumption. This will at least let you see how much consumption is due to these more power intensive services.
If you still have issues, you may have a battery problem (or may need to try reflashing a ROM, stock or otherwise).

Yeah, that's a tough swallow just for the sake of battery. I can compromise on the location service, but really want 4g since it is so widely available for me. I will attempt to recalibrate the battery and then possibly reflash if I feel it's still a problem. Is there another rom you recommend that can possibly mitigate this issue. I tried Gummycharged on my phone but it is really buggy (launcher force closes every few minutes) on my device for some reason.

Depends on if you want a Froyo or a Gingerbread ROM. I was running the Eclipse Froyo ROM with the imoseyon kernel overclocked and undervolted slightly and had excellent stability, performance, and battery life. I just switched to a GummyCharged GBE 1.9RC2.3 but haven't really decided yet if I'll stay.
Probably Froyo

Thought about it for a while and will be sticking with Froyo for now until Gingerbread has been officially released from Verizon. I'm hoping that will allow for most of the bugs to be reconciled. I read in various post that GB still has some issues. Stability, performance and battery life are my primary concerns.
On a side note:
Don't quite know if I am ready to start overclocking and changing voltages. Is there a recommended thread to get some basic knowledge on working with the voltages and what not. I only have experience overclocking desktops and graphics cards.
Thanks for following through with me on this as well.

No problem, I used the clock and voltage settings in this post but only used the Temperature profile. Had no issues. I tried straying from it but started getting crashes so I went back to it. If you're looking for only battery improvements, you could skip the 1300 Mhz OC and just underclock and undervolt. That whole thread is devoted to an OC kernel though so feel free to read through and it may shed more light on it.
Hope that helps.
Awesome. Thanks

Automatic brightness will use more battery than setting it to one brightness and manually adjusting it as needed. Automatic brightness requires activating and polling the light sensor, then increasing/decreasing the brightness. On top of that, I've found that automatic tends to keep the screen brighter than it needs to be for me in most situations.
Good point

5% drain in last twenty minutes. Just Lte on and no activity but writing this post.
Sent from my SCH-I510 using XDA Premium App
20% drain per hour of screen on time is the norm for Charge. Throw in the typical idle background drain of 4% per hour, and you'll see why 3 hours of screen on time per day is the max you can get.
Now then, the drain due to active screen use is expected and can't be improved. However the idle drain is unusual and *probably* can be fixed by future Samsung firmware. (gingerbread is not fixing it yet). I'm guessing its poor idle radio management, which is why undervolting the core does nothing to help.
If the idle drain can be greatly improved, the Charge could then expect to get 4-5 hours of screen on time per day, and I'd be a happy camper.

I'm in the same boat here with Humble 1.51.
4G at 4 bars, -84dBm, surfing the net, 30% back light, no gps, no wifi, 2 gmails syncing -- 20%/hour.
Brightness is at the lowest setting for me, Twitter, Facebook, and Beautiful Widgets syncing hourly, 2 Gmail accounts with push notifications, Google Voice, and possibly a few more background apps. I'm at just over 4 hours being unplugged with 20 min. of screen on time and my battery is at 75% and was charged fully when I unplugged it. I have not had any major use as far as playing a game or major web surfing either.
I have good luck with imoseyon's lean kernel 0.13.3 and gummycharged fe. I had very poor battery life before i tried that combo.

Go back to Stock. Completely wipe everything (including SD Card ... this is optional probably, but it's what I did. Make sure you back up on your computer). Then re-flash your rom. I had this problem after switching initially from Froyo to GB. My battery life is amazing now with the new GC GBE 2.3.

I've seen you post this on other threads, and it just proves that different users of the Charge have different experiences. I think a lot of it has to do with the network.
I have had my phone off the charger for 10.5 hours now at home, which varies between a moderate and weak signal. It is still at 81%, which means it has had a 1.8% per hour battery drain. It has been mostly idle, but I've sent a few texts and quickly browsed a website. If it was truly left alone, it would be even less than 1.8% per hour. This clearly debunks your one-size-fits-all claim of 4% idle battery drain.
As for screen on time, I've done 2 hours of screen on time during an 8 hour day and still had ~48% left. Doing the math I could get ~3.85 hours of screen on time in a 15.3 hour day. My battery drains quite evenly with no sudden drops, so this would be a fairly accurate and realistic expectation for me. If I really needed to, I should be able to get ~4.55 hours of screen on time in an 8 hour day. This is based on my high of 1.8% per hour idle drain and 18.8% per hour screen drain. Or, if I did a 10 hour day (like I do quite often), I could do ~4.35 hours of screen on time. Once again, your sweeping generalization of 3 hour max screen on time certainly doesn't apply.
I don't have any special or magical configuration either. I leave 4G on, which sometimes drops to 3G at my house since the signal is weak at times. I leave the GPS and bluetooth on at all times. I have the screen brightness set on automatic. I also have Gmail setup with one push email account and leave auto/backround-sync on at all times.
I run Imnuts' PBJ voodoo kernel with a stock deodexed EE4 system and got rid of some of VZW's bloatware. Mind you, I haven't noticed any significant difference in battery life between the fully stock stock EE4 and the current configuration.

So, I recently cancelled AT&T but I wanted to make a couple of last remarks on a battery issue, so as to (hopefully) better inform the devs. Up front, I will say that the reception at my house is terrible (hence my cancellation). As such, I expect somewhat poor battery performance. I have run nearly every version of Cognition, tried the AOSP project, and most recently run Perception. After using these, I was left with the impression that the battery performance in all of these has been disappointing.
Having received my new phone and with my old service not yet deactivated completely, I decided to try a more formal test. I used the following test protocols in order to ensure a fair and accurate comparison was conducted:
1) The phone was positioned for the worst possible reception in my house. It was only moved to change ROMs and was returned to the approximate location it was previously in.
2) Each ROM was flashed at 100% battery, with SIM and SD Cards removed.
3) A battery recalibration was performed after each flash, as detailed in the Cognition thread (Charge to full, turn off, charge to full, turn on, use for 2 minutes, charge to full, delete battery stats). Following this I did one more complete discharge and recharge to ensure the statistics would reconfigure with the calibrated battery.
4) GPS and Bluetooth were turned off; WiFi remained on and connected through all test runs.
I loaded Cognition version 2.3b6 and then Perception build 3, both of which performed approximately the same. Leaving my phone on standby and with only very light use (0 answered calls and no internet surfing or messaging), I could get no more than 15 hours of battery power before it died. Following this, I restored my phone to the stock JH7 update and, as of now, my phone is at 54% after 2d 19h 25m of use.
I know many people have been flamed for daring to suggest that the ROM has something to do with the battery draining abnormally, but I did this test as objectively as I could so that the community of developers can use the information to improve on this issue. In my opinion, this test suggests that something in the custom ROMs is causing an excessive battery drain. While this may not be happening on everyone's phones, it is most definitely happening on two of my Captivates. Hope this helps and good luck! I am off to Droid X Land! Suppose I'll use my working GPS to get there! (Sorry, couldn't resist... too soon?)
Edited for grammar and clarity
Poor signal is the biggest battery drain. Especially in 3g areas. I have had phones on VZW and ATT (different times and locations) where my battery would not last 8 hours.
Another test to show it is not the ROM or OS is to put the phone in airplane mode and observe almost 0% battery drain overnight.
But since these custom ROMs are built off beta releases, I am not surprised by your results.
Sent from my MB520 using XDA App
I noticed the same thing a while ago and am just hoping there is some issues with the fact that these roms are being developed on leaked builds without the source code.
The key thing to notice in the attached screen shot is the near constant 1-3% cpu activity when the phone is not being used. On JH7 I could leave my phone on over night and only lose ~3% battery. Currently on Perception build 4 I lose ~20-25% overnight. On Cognition 2.3b3 I lost about the same.
I get about 16 hours on my captivate with light to moderate use on the froyo leak.
on Perception and Cog (latest builds) I was getting about 9-10 hours with very light use.
I need another battery

I doubt the battery is your problem. As my test suggests, I am pretty confident that if you were to restore to stock, you would find your battery risen from the dead.
I can vouch for the OP about battery life. Battery life on JH7 is WAAAAYY better than any custom 2.2 ROM. I am running stock JH7 with Atimns v1.10 Voodoo kernel. Beats the pants off of the Cognition 2.3b6 ROM I was using battery-wise. In my experience, all of the Froyo based ROMs have battery issues. :-(
I just searched up a little bit more and found that the sensor is using a lot of juice because of a bug in the picture gallery app included in all froyo roms/leaks. I checked my sensor use and sure enough it was at 6 hours non stop. uninstalled using root explorer installed the Gallery3D.apk found on this site and now the use is at 2 seconds. I hope this was the cause. Also, is the android system supposed to be using so much of the sensor? My phone has been on for 11 minutes (reboot) and the battery history in *#*#4696#*#* says its been on for exactly the same amount of time...
sorry for the thread jack!

The issue with the gallery using the sensor has been known for some time. If you our the rom dev did not change out the apk, you should.
Well I changed it and my battery has been going great! Heavy use with 5% decrease per hour since I replaced it.

To be fair...the custom ROMs I have tried each had WiFi set to always on. The stock ROMS from had is set to only be on when the screen was on. Depending on the availability of a WiFi AP, this can make a huge difference. Looking for a WiFi AP to connect to is costly.

In my case, this was not the difference for me. I always had my WiFi always on, even with the screen off. I turned it off manually if I know I am going to be some where WiFi is not available. The battery drain is definitely somewhere else....but these are leaked Froyo ROMs for a reason.

It depends. If there is a lot of data transfers going on and WiFi is off with the screen, these transfers will take place over 3G, which in more cases is not as power efficient as WiFi, all else being equal.
I'd say, WiFi always on is better, in my experience anyway. Mileage may vary.

For me personally I get terrible battery life when wifi is on. Everyone on here seems to say that leaving wifi on saves battery but this has never been the case with any device I've ever owned . And I'm talking about when I'm sitting home in an area with good wifi reception too.
I can't figure my battery out at all. On the weekends if I stay home and keep wifi on my battery will be on for 20 hours and still have 65% left. Once I leave home and I'm using 3G I can only get about 5 hours. I've lost 20% or more per hour without even touching my phone.
Another weird thing is under battery usage and "cell standby", it always shows time without signal at 50%. Never more and never less, always 50% exactly. Any ideas?

Wish I had the answer for this too. Mine says the same exact thing. Always 50% yet I always have signal where I am. I'm hoping it's some sort of miscalculation and not a major bug where network connections are being dropped constantly and not being shown.
I get three+ days with my phone...
Sent using smoke signals.
Man, I thought I was in my own boat. Same exact symptoms across Cognition, Perception, Axura, you name it. Something weird though is that the first day is always great on battery, then after a night's charge it goes back to the 12 hr max per day (moderate usage). On stock it definitely lasts a lot longer. can't wait for an official froyo release... especially now that I have to use Good Messaging, another huge battery hog.
There are a lot of battery threads out there, but i wanted to try something new. I want to see how much our phones drain in real world situations. So here are the rules:
1. Use your phone normally for ten minutes.
2. Note your battery percent at the beginning and then at the end.
3. Post details about what you did, what ROM you're using, and the percent battery drain.
Hopefully we can compare our experiences and learn something.
I used my phone to surf a few websites, send one text, and use xda app. Started at 80% and ended at 77%. Using rcmix3d at 50% brightness.
I know there are tons of factors that affect battery drain, and I'm not trying to be scientific. I'm just curious how we all compare!

The only way you will get a decent idea is to test with others in your area as it will depend alot in signal strength. I would use more battery if I was bouncing between signals instead of having a steady connection.

Screen-on time is the only thing I ever look at. I've only managed to squeeze about 5h45m, out the sense-based gb ROM I've been using.
The phone does really well in standby on most if not all roms that have been flashed properly, don't have non-rom-related battery hogging app issues, and, as zelendel mentioned, signal issues.
It's this big fat screen that's obviously the biggest battery sucker.

I've gotten accustomed to putting my phone on the charger before bed as well. Mine pretty much will last the entire day... Off charger at ~8-9am, back on it at ~12am.
Averaging about 5 hrs screen on time with usually no voice calls of significant length, WiFi on, gps off, relatively stable signal.
I'm running Inspired Ace 1.0.1, and the 04.11_M2 radio. Seems I was getting a little better with the OTA radio, but signal fluctuated a lot more on that one, than with the 04.11_M2.
Edit: doesn't really use your testing procedure, just more of a general feeling, as there's so many other contributing factors...

Holly crap that's a heavy drain. I couldn't possibly use this phone with that type.of battery drain. Thanks to our great dews I managed a little over 7h screen on time. Could only accomplish that by reducing the screen brightness and UC to 768mhz. Stick speed and auto brightness I get about 6-6 1/2 screen on.

You probably got a bad flash, or have something else running, as I mentioned in your recent thread.
Did you full wipe prior to flashing?
Try out gingerbeast, if you still have battery issues with that, after properly wiping prior to flashing of course, then it's hardware, as that ROM has produced some record-breaking battery life performance.
Mine has twice decided to randomly have days where it just drains like crazy. The battery is a lot warmer and just dies out in like 6 hours with very minimal usage. the majority of the time my battery is great but the last 2 days and then about a month ago it did this. No reason for it either, I have made no changes on my device.
Anybody seen this?

Yeah I did a full wipe before flashing. I'll be sure and try that out tomorrow, I really hope it helps. If the issue is hardware, should I contact HTC? After I believe you said my phone should still be under warranty, I called them, and indeed it is. The rep I had before must have been new or something. Thanks
From a full charge, on TPGB with wifi, gps, and sync on, and everything refreshed 3-4hrs, I lasted about 8 hours. I was using super accurate gps for 20 minute intervals or so, but it lasted the day I'd say. Some occasional web browsing.
Lucky for me my head unit on my car has a usb port. For this whole trip I left it off though.
ok so here's the deal.. my phone has been off the charger for about 4 hours and im already down to 40% left. I live in a 4g area but it is spotty in many areas, including my workplace. I have gps (for weather updates and nav, when i need it) and wifi on at all times. i am running the EP4P modems on GummyCharged Froyo ROM 2.0. I have the screen brightness turned all the way down. No overclocking.
Kernel: 2.6.32.9 [email protected] #30
I have tried several different methods to calibrate the battery but it doesnt seem to help. When i'm at home and using wifi the battery life is pretty good. so is it my modem? the ROM? my kernel? Can anyone help me get the most out of my phone? I've tried various modems but have stuck with GC since I loaded it back in sept.
If you are in a spotty area, that can happen. Searching for signal and 4G/3G switching can drain the battery very fast. I would try putting the phone in cdma mode while you are at work or any other spotty area.
Turn off wifi and gps if you are not currently using them, wifi scans for networks regularly and you may have apps/widgets that are using the gps/ network location services while you are idle
also, my battery stats say that display is using up 45% (as of now) of my battery life with 23 mins of usage time. I have the wifi turned on for my convenience, but it doesn't scan for networks as i've turned that function off. I will try the cdma switch, but I have also tried that before and I don't think it makes too much of a difference.

The battery usage metrics aren't useful until you've been up for several hours. And having the screen using a high percentage is ideal -- it means that the rest of the system is throttling like it is supposed to.
How long have you been on GummyCharged? A few weeks into having that on my phone happily, battery life took a nose dive similar to what you are experiencing. I flashed back to stock and battery life is much better. Waiting for official GB before trying another ROM.

i see your point but im now at 5 hours uptime with 23% battery left.. light/medium usage. display still says 46% battery use with 25 mins of usage time. that seems like incredibly too much battery drainage.
also, when i put the phone into cdma mode do i select the home or automatic option, and what is the difference?

i flashed GC onto my phone in mid september. since then i've tried calibrating the battery several times. a totally futile exercise it seems. What setup are you running now? 2.2.1 with EE4 modem? Rooted?
The only thing that has solved my battery problems is juice defender. Sitting idle for eight plus hours at night I only drop about 3-5%. Of choose it still drains just as quickly while using the phone but it will help if you're in a spotty area because data is turned off if your screen is off.

I have similar issues. After rooting and flashing Humble on my phone, my battery life sucked, much much worse than stock.
I then put the standard 2.3.6 on it and it still sucks. Full 4G all day, barely use it.
It's sat on my desk at work all day today. Sent a few texts. I've installed betterybatterystats and nothing is taking up a large portion of partial wakelocks.
Really don't understand how people are getting such good numbers...
I find that by far and away the best way to increase battery life is to lock my phone in 3G unless I am downloading something & want the 4G speed.
I have a home screen widget that turns 4G on/off & only turn on 4G occasionally. I do not leave WiFi on although I leave GPS on at all times & find that uses almost no battery life whatever.

I thought my battery was bad then i looked at that graph. I don't even get it... The screen is mostly off and the signal is green most of the time.
It may be some rogue app on your phone. Backup your apps and do a factory reset. If your battery life significantly improves, restore your apps one by one and find the culprit.

Just stock EE4, unrooted, will do OTA as soon as I get the notification. Battery life is not that good, I can get 14 or so hours of use leaving it on 3G most of the time, but on Gummy I would get 50+% drain just having it sit overnight. Now leaving it sit overnight doesn't kill it.

ok so here's the deal.. my phone has been off the charger for about 4 hours and im already down to 40% left. I live in a 4g area but it is spotty in many areas, including my workplace. I have gps (for weather updates and nav, when i need it) and wifi on at all times. i am running the EP4P modems on GummyCharged Froyo ROM 2.0. I have the screen brightness turned all the way down. No overclocking.
Kernel: 2.6.32.9 [email protected] #30
I have tried several different methods to calibrate the battery but it doesnt seem to help. When i'm at home and using wifi the battery life is pretty good. so is it my modem? the ROM? my kernel? Can anyone help me get the most out of my phone? I've tried various modems but have stuck with GC since I loaded it back in sept.

you prob shouldnt be using that ROM..its kinda outdated...just flash the new ALL IN ONE ODIN of EP4D...my battery life is pretty sick...i left it unplugged all night and saw a tiny drop..my phone was connected via wifi tho..if my phone is in 4g the battery loses pretty quickly or if my screen is on ultra bright..
I'm running the stock, rooted, manually-debloated EP4P and I've been getting downright stellar battery life.
My kids watched an hour of Netflix this morning while getting ready, and now (almost 10 hours later), I'm still at 63%.
But! (and here's the kicker) - I leave WiFi on all the time (I'm contemplating buying Woofi to save even more battery when I'm not at home or work) and have my WiFi sleep policy set to "Never".
This is (one of) the key(s). It doesn't matter how strong your 3G or 4G signal is, WiFi will always save you battery. 3G is less battery intensive per-time, but much more battery intensive per-byte. 4G is less battery intensive per-byte, but much more battery intensive per-time. WiFi is much more battery intensive per-time, but wildly less battery intensive per-byte.
In other words, for the same download, you'll use the least battery on WiFi (even with a slower than LTE connection), 4g in the middle, and 3G the most.

is there an odin file for what you have or did you do the manually debloating after rooting?
I am opening this thread to facilitate skyrocket users to share their experiences on getting most out of one charge.
I generally prefer something that shows percentage on top since the battery display does not provide detailed info.
I have tried few free aaps and finally found the best one. It is '2x battery' app. I used to loose 4 - 7% per hour in standby mode. With this app, It gives me 1-2% most in burn in hour. While writing this, I am 36% after 17 hours of regular use.

im at 11 hours and have 89% left using Juice Defender plus..
The only problem with JuiceDefender is that if you use messaging apps like Kik or WhatsApp, it will make it so that you don't receive the messages unless you have your phone active, making your phone pretty much useless.
I dont buy anything til I see proof of screen time and battery use screens.
Just got the phone yesterday, but I must say, coming from the epic 4g touch where I was getting 25 hours with 5 hours screen on time, it doesn't look promising.
But to be fair I haven't underclocked, undervolted and all the other tricks yet. Properly working sleep mode is essential.

I will try the 2x battery,
I use JuiceDefenderPro; custom profile
After 7 hours on battery, I am at 90%.
light calls, 1-bar of signal on 4gLTE, apps grab data every 15 minutes.
Anyone see results w/ underclocking?
I am using Antutu's CPU Master (Free), but my results have been inconclusive (sometimes uses less, sometimes uses more.. can't tell). I am considering getting the paid version of the app (or SetCPU or Android Overclock) to try the screen off profiles.
I use set CPU to underclock when the screen is off and when battery is low. In my experiences the savings are noticeable but not major.
With set CPU, juice defender, and a de-bloated rom I usually go to bed with around 30% battery remaining. That's about on par with my nexus one running cm7.

I haven't really had issues with the battery on my skyrocket. Then again, I'm not I'm an LTE area but you can pretty much expect bad battery life in an LTE area. Regardless, I have noticed something odd about the battery on my skyrocket, and maybe someone can confirm my observations here...my skyrocket tends to lose battery fairly constantly at first up to about the 80% mark then slows down the rate off loss of charge and I notice another huge slow down in drainage at the 30% mark. I've seen this repeatedly no matter what I do. In other words, screen on or off, I tend to see this happen. I'm not complaining as I think a 20 hour battery is great when using it heavily. And I kind of think of the slow drainage at the 30% as a nice perk. I'm running it stock so I can't chock it up to anythnng other than the phone. Any thoughts?

Why does everyone say this about LTE? It is simply not true. All LTE does is give you higher bandwidth with less delay. Wan't good battery life, run a custom ROM. I am running the ICS v4.1 and I must say it is much better than anything else I have tried. I keep 4sq, FB, twitter and gmail all running in the background along with BeWeather updating every hour.

Everyone says that about LTE because (from what I've read) running LTE requires more power due to several reasons. I did a quick search and sprint may be a great indication of proof of the power consumption of "4g" from what I've read their phones disengage wimax when not in use in order to conserve energy. If LTE is faster and operates at higher frequencies (if I'm not mistaken) then it should require more energy. I could go outside the box and come up with some equations that relate frequency to energy (they exist) but I will admit I don't know if they can be applied to the circuitry in phones though I don't see why it wouldn't as the theory is sound. In any case, yes running a custom rom will do wonders for battery but some of us haven't taken that plunge yet. As it is, my stock skyrocket is doing great for me lasting 20 hours. Im out of the house at 6am and usually don't get home till 8 at night. It makes it through that with ease. I'm happy with that. Bring on the LTE, I'll cross that battery consumption bridge when we get there.
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.

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.

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.

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. ;(
