I am running current widget. This phone is a beast and eats 250mA while idle while my OG droid only was taking 20-30mA. no wonder this sucker dies in 4 hours
That shouldn't be that high when idle. I'm doing idle power tests right now, all the time in fact, on my nexus. Checked the thunderbolt and inspire at the store. At least they seem more efficient with screen on, hitting around 430mA at max brightness. My nexus will hit 750mA which drives me nuts.
I'm comparing ginger bread idle power, and Google seems to have made enormous improvements. Idle current draw is now at 8 mA, where on froyo for me its around 18mA. More testing needed.
But I feel that slcd screen is way way better for power than the amoled since most uses show white color anyway.

well its pretty consistent idle power draw of 200-250. i have 4G on and syncing on as well. When i am using the phone with the screen on i average around 450-500. when i turn of 4G and have good 3G signal i can get the phone around 45mA
45mA is still high. I just wiped my phone because I'm averaging 50mA idle all the time no matter what. On this clean install I'm now at 15mA very consistently. But what's driving me nuts is I loaded stock ginger bread, and that ROM stays dead even at freaking 4 - 7mA. It's beautiful, my battery lasts incredibly long on it. But switching back to cyan7 I can't get below 14mA, and its driving me mad.
I just swapped ROMs again a few hours ago to do more tests. I hacked the nexus battery driver to do some useful tests. Wonder if the thunderbolt uses the same driver.
My idle draw is an average 40 with 4G. I'm using the current widget.
It also draws the same on airplane mode. Something is screwed up somewhere...

Your posts aren't very informative for someone trying to compare.
What apps are you running background, which services (sync, location, etc), which radios on (wifi sleep policy, BT on, 4G/3G area, etc), screen brightness settings? Even the app will have an impact on draw, since keeping a log file will cause some juice drain each time the log is written, so update interval is probably necessary for the discussion to be meaningful.
You're getting your numbers from the log and when the phone is actually truly idle (ie. untouched, screen off) for a while?
Not criticizing at all, but these kind of discussions can end up just frustrating folks because of ambiguities...kind of like the posts where someone says (I get 5 days on my battery with "moderate use", and it turns out that guy's idea of "moderate use" means it sits untouched all day except a couple of minutes browsing).
I just installed the current widget out of curiosity, so not much data to go on, but with the screen on 50% brigthness, wifi on, BT on, sync on, several apps having been opened I saw about 140mah. Turned the brightness down to minimum and it dropped to 76, then 45. Let the phone idle scree off for a few minutes, and it was showing 32 when I first turned it back on.
My log shows that during the idle period for a couple of minutes, the phone was drawing between 30 and 40 each pull (every ten seconds).

Ill post a copy of my Log later on. Right now the results wouldnt be fair because i am at my parents place and their house is made of some material where you go from 3 to 0 bars of reception when you walk in the door. But usually my general setup is 3g/4g on wifi off, BT on but not connected to anything, GPS on but not actively lookin for sataillites, and then a bunch of my regular apps. I mean let me put it like this. in my first post i discuss the difference i have seen in current consumption between the TB and my OG droid. The phones are set up EXACTLY the same with the same programs running in the background. The only difference is the TB has that extra 4G radio. I live in West LA so generally the coverage should be 100% 3g/4g. anyhow ill get a copy of the log.
my currentwidget is almost always above 100mA and ive got 4g off, wifi off, gps off, BT off, no apps running etc. very frustrating to see this phone die in 6 hours no matter what
This has been my experience also. my history from last night showed a peak of about 400mah discharge and a min of about 120 mah discharge. Not sure what is going on.
I have wifi off, bt off, gps off(using vzw location services though), with words with friends, double twist, battery booster, goog voice, lookout, bat indicator service, myphonemrules, simple service, craigs checker service, weather toggle widgets, nobars, night time service, battery monitor widget, and swiftkey, the rest are vzw bloatware services or htc processes in the background. Backlight is at about 30-40, and timeout is set to about 1 min. Since the last restart I have gotten as low as -50mah and max is about -350. I can't say what all was running during the night because I changed few things this morn to try and fix my drain, which as seemed to help, but not a lot.
Attached is a copy of my history since 3/24.
Once we are able to undervolt our kernel, our idle usage should drop significantly. Until then, I'm keeping a charger handy and waiting for my eBay batteries to get here, lol.
I have the extended battery, which I can't use with my case of course, if I really need it. But I like having a case on my phone because I shattered the screen on my D2 a week after I got my last one. Not trying to do that with the TB.
so to revisit this post a couple months in.. i am on the new GB leak. still idle at 40mA still sucking power like nobodys business.. wtf

I unplugged the phone and got onto the bus. I read news with Captivate. Nothing fancy, just NY Times, Fox News etc. I got off the bus later, I only have 73% battery.
Yes, I just started my day and it's only 70% of battery.
#FAIL.
There are a few simple things you can do to increase battery life. Turn the screen brightness down and use a solid black background as a wallpaper. The screen uses the majority of the batter. so dimming the screen helps, when using a black background the amoled display does not light up black pixels so there is power drain.
I've been running on the same charge since 4pm yesterday. I've streamed music through pandora for about an hour while exercising, browsed the xda forums using the XDA App for 30 mins, made a few calls, browsed Facebook for 30 mins, surfed the web for a couple of hours before bed. Its now 10AM and I'm sitting at 36%. Not to bad really! The phone functions exactly the same at 36% as compared to 100%.
I wonder why everyone says to use a solid black background? Do most people use their phones primarily by staring at the home screen? I'm never at my home screen more than perhaps five seconds while switching apps
I've had pretty poor battery life as well, even after discharging, recharging, and deleting batterystats.bin. There are small tips here and there, like black background and screen brightness, but even following them all, my phone lasts me barely ten hours, and most of that time it's idle. For instance, I listened to local must (no streaming) with the screen off for about an hour and lost 10% of my battery life. What's up with that?

I am also shocked and confused by how people can use their phone so heavily.
I already killed those unnecessary processes (e.g., all AT&T crap). I have a static wallpaper. I have screen brightness at 60%. And all I have been doing is just reading news and surfing the web. It literally cost me 1% of battery for every 1 min of use. It's just ridiculous.
You are probably on your home screen a lot more than you realize.
Anyway it's a smartphone, they all eat through battery time. you will never get superb battery life unless you crowbar a 3000mah battery into your device.
edit:
set the screen on its lowest brightness setting, the only time I've had to increase the brightness is when I am outside in the sun.
if you are on a bus, if you are not using wifi, turn off the radio.

I have Wifi, BT always off. And I don't listen to Pandora.
I think the key is you have the lowest brightness on your phone. It is going to save you a lot of battery 'cause half of the battery is for the screen.
But I just couldn't stand it. I wish I can set to 100% all the time. It looks so much better.
The phone radio is a huge consumer of battery - especially in weak signal areas. The bars are not that accurate either. that coupled with 3rd party apps that don't always behave nice, can equal rapid battery drain.
Putting the plain in Airplane mode is good way to see what battery life is like without the Cell radio always doing its thing. It is not a fix, but it can show that the battery/phone are not broken. There probably can be improvements and tweaks made by samsung, but I don't think the phones are defective.

This is what you would call a trade-off I like the bright screen also but I like having longer battery life more.
The screen is still pretty bright on it lowest setting and you gt used to the lower brightness after a while.

how are you using your phone? What apps are you running, are you using any emulators.
There's an app called Spare Parts, which will show you what is using your battery when the screen is off. Open it up and choose "Partial Wake Usage" from the drop down to see.
My Captivate appeared to drain battery very quickly, but with moderate to decent usage throughout a day I was trying to kill the battery it lasted me over 13 hours. I think it's a matter of the battery reporting taking a good while to calibrate properly.
I've had an issue twice now with absurd battery usage. Both times I charged the phone to full and disconnected it; after doing that the phone would lose 10% charge every hour sitting completely idle! Using the phone during that time drained it even faster. Both times powering the phone completely off and back on resolved the issue.

In AMOLED, black pixels dont use power. This is different from LCD where even black pixels still use power.
Have you guys tried fully charging, then fully discharing then repeating this step 3 more times? It helps with the battery life tremendously.
You gotta do a factory reset. Many people as well as myself had the same issue. For me, a side effect was also that the att start up swoosh was stupidly loud.

I only did the discharge thing once, last week, and today I am going on a 21 hours with 28% left.
2g app
I was told there is a 2g / 3g application. Has anyone tried this? Apparently it puts the phone in 2g when no data connection is needed and then updates to 3g when a data process is required...
i'm on day two of not charging mine... and i'm at 25%...
i unplugged it from a full charge yesterday (monday) morning before i left for work and today (29 hours later) i'm at 25%... this is with advanced task killer auto killing tasks when screen is off as well as being aggressive about it. i've been listening to music from my sd card, browsing facebook and taking some pictures (and uploading them to fb). i guess i'm either super lucky not to have any problems with GPS or the battery, or i'm a very light user.
I dunno what happened to the main battery thread?
I just got a new phone two days ago because of the restart issue. This one has the same battery issue. Drains 2-4%/hour just being idle. I have nothing beyond launcher pro and google voice installed. Everything is on lockdown in terms of batt usage. The only thing I haven't done is turn off the cell antenna.
I've tried the tricks I knew: factory reset, calibration trick. These didn't help at all. My last phone just needed a factory reset and it was all good. Now I'm sad again :-( will it just improve itself when the phone "learns" the battery or something? I wish I could teach it
Several things you can do.
1) Use WiFi if you can use it, it uses less power. If you don't have somewhere to use WiFi, leave it off.
2) Same goes for BT- leave it off if possible.
3) Use this to get rooted and remove all the ATT crap that sucks battery life. Applying the lag fix also means you spend less time with the screen on, so that can also help you out.
4) Use Auto Brightness
5) Disabling haptic feedback and the tapping sounds (I find it more annoying regardless)
6) Use a static black wallpaper- or something really dark. IMO it looks great black and plus the AMOLED... Black doesn't use power.
7) Use Advanced Task Killer. I have mine on Aggressive and Moderate security every half hour. This will make sure hung apps, etc get killed and apps you haven't ran. Make sure you whitelist the apps that run your widgets and such though.
That's the best things to do to.
Edit- above all, remember this is a SMART phone, not a feature phone like the iPhone is. The simple fact this full blown SMART phone can even begin to rival just a feature phone like the iPhone speaks volumes to how much more efficient it is than what you think it is.

I too have had issues with battery life but quickly realized what had been causing the issues, twice it had been snesoid not closing down all the way after use, and this combined with an app that was hurting battery life (word feud), I realized what my problem was.
I leave the brightness jacked all the way down. I believe the lowest it goes on the stock rom is like 15%, but there are ways to go lower than that.
I've not used my phone much the past two days since charging it, and i'm currently down to 35%, but most of my battery use is cell standby, with display being 3rd or so on the list.
You can always use a program like tasker to make the phone go into airport mode between certain hours of the day (IE: while you're sleeping) to help conserve the battery life.
There are also tons of other good tips in this thread.
And trust me, the phone can last; i've managed 3days on one charge
I am getting absolutely horrible battery life on my MT4G. I took it off the charger at 9:30am, I have since made one 5 min phone call and sent maybe 5 texts, and checked a couple emails that i just deleted, other then that screen has been off the whole time, its now 4:40 and im at 35% battery. On my Vibrant with this sort of use I would still be in the 70s.
Under accounts and sync:
facebook updating every hr (just changed it to every 4 hrs)
google syncing just gmail, no contacts or calender
news every 4 hrs
stocks not syncing
t-mobile syncing (tried turning off but it just turns itself on again)
qik video chat syncing
weather every 3 hrs
yahoo syncing
Are you on wifi or 3g? Brightness? Screen timeout? I have an N1 and the battery life is pretty poor so I'm just curious apples to apples in terms of what else you have turned on.

ever thought about turning off 4G? You don't alway have to have it on.

Don't bother with that battery charger hack, it's not going to do anything but waste your time...
I just installed SetCPU on my phone just for fun and have found that it recognizes a few lower clock cycles...I added a profile to lower the CPU when the screen is off otherwise at 1024-245 On Demand and I'm still plugging away at 20% battery when I would normaly be on the charger by now...could be a fluke, but so far so good...I'll keep this for a few days to see how it does.
oh, one other note, my battery life has continued to improve with every charge...the first few days I couldn't get through a full day and now I have battrey to spare...just had to get it conditioned with a few charges I guess.
I let the phone completely die last night and then charged it and at midnight I unplugged it. At 8:30 this morning when I left for work it was at 94% which was great but from 8:30 until now it has dropped to 83% and ive had one 3 min phone call and deleted some text messages, no browsing web, no listening to music, nothing. It seems like the phone will go through the 100-95% slowly but after that its in a marathon to get to 0%
I don't know how you guys are getting so many hours daily on heavy use. I get 7-8 hours on heavy texting, some web browsing and about an hour plus on the phone almost every night. 9 hours would stretch it and it would be on 10%.
I have my brightness all the way down and all the way down is just 11. Screen times out in 2 minutes and I have power saving on. I did the battery thing 3 times where I would let it go down to less then 14% or so then charge it fully without taking it off charge. Hopefully it improves as days go by, I'm just tired of carrying my charger to work.
myTouch4G (Glacier)
Down to 69% now at 11:15, have made no phone calls or texts since then, have just downloaded opera mobile but havent even played with it...lol this is riduculous
I can recommend that you guys take a look at what might be pinging the CPU. Watchdog (Lite) is great for this task. You can have it alert you when an app exceeds a preset threshold for CPU usage. Some apps just go rogue on you like Palin from time to time.
I've also noticed that there's wide variability in terms of how apps go into either idle or background states. Some apps will go into idle only if you hit the back key to go back to the home screen and will enter a background state (more active) if you hit the home instead. I've also noticed that the free, ad-supported apps require more CPU time. That's right. Hitting Google's ad servers, at least for some apps, and scrolling those ads, requires more CPU time than other apps, which do the same. I don't know whether to fault the devs in this case when coding for the ad retrievals or not. Just some things to consider.
I just got mine. I came from a Blackberry 8900 and an old 2g iPhone. Battery life on both of those was significantly better. I could talk for 8 hours a day on the BB and it would last until midnight-1am or so. The iPhone would only last until 10pm.
Using the MT4G, my battery life is REALLY bad compared to these other two devices. I can get about 5.5 hours of continuous talk time, tested yesterday on a conference call for work. But even with only calling for about an hour and some basic email checking, I can't go past 6pm without putting the phone on the charger.
Wifi is off, screen at 50%. Someone please make a big fat 2800mah battery for this thing. I use this thing for work, and I make over 4000 mins a month of phone calls. It's really annoying to have to plug it in whenever I have the chance.
im getting roughly about 15-17 hours and im using it (camera, blogging, facebook uploading)
this destroys the EVO i had
Heavy usage, I'll get around there, 7-8 hours...regular usage gets me around 20 hours..I'm using setcpu w/ profiles..

i notice my nexus 1's battery is significantly worse when i'm at work since getting a signal is a bit spotty (35th floor) so it keeps searching around. when i'm at home the battery lasts literally twice as long while idle.

I think I only brought my G2 into work a couple times so cant really comment on that but in the 3 months ive owned the vibrant, if i used the phone a lot during the day....i mean play games, texts, web, etc..id leave with percentage in the 50s, normally in the 70s, at 4 today i was in the 30s with the mytouch with barely doing anything, since i want it to last until the night i just threw it on the charger. it shows I have full signal (4th floor by window)
My wife just got an mt4g (I have a nexus one). I've noticed that her battery life seems to be just over half what mine is, and I actually use mine more!
When I looked at her Battery Usage display, Android OS was near the top with almost 2h CPU time after being unplugged for 6h. For comparison, on my nexus one, CPU time for Android OS is 4m13s after almost 8h.
Any good way to break that number down more and find out the source of this crazy battery usage?
Keepin' it clean by keepin' smooth...
Ok finally after a few days of using my phone it has finally leveled off. My phone has been off the charger since 6am and I am at about 70% charged. Couldn't ask for more out of a smart phone. This is right in line with my Nexus One so I am no longer disappointed.
There are a few tweaks I did make to get this working this way.
(1) Screen brightness set at about 20% - The TB's screen is way to bright to begin with and making this adjustment is something that is not very hard to get used to.
(2) Screen Time out at 30 seconds - Setting to low will get frustrating if you like reading the news on your phone or browsing the web, 30 seconds seems just right for me.
(3) WIFI when not in car (triggered on and off by loss of Blue Tooth Connection and Not In Dock) Using WiFi instead of relying on your data connection will help save some juice while in a WiFi enabled building since your phone will not be trying to constantly search and connect to a data connection.
(4) Blue tooth off until docked - Saves battery by not transmitting a BT signal constantly. I only use Bluetooth in the car so triggered by the dock seemed logical.
(5) Syncing Facebook every 8 hours, News every 12 hours and Stocks (Who really needs this)
(6) I love widgets on my home screens so these get updated as I found necessary to me. Im not a major facebooker that needs to be on the bleeding edge of everyones life so 8 hours is probably even too much but adequate. News doesnt really update very often and compared to a daily news paper 12 hours is more than ample. Stocks, need I say more seriously I am not an investor and could care less.
(7) Over clocking your phone is not necessary right now, 1 GHZ is definitely more than you need on this phone. I am scoring about 1700 on quadrant which is pretty good for a 1ghz phone. My phone has never lagged and has functioned as expected since birthed to my hand. Keep in mind Over clocking will increase the performance of your phone but will tear at your battery as well and may cause heating issues.
(8) Not using an animated wallpaper. Even on my nexus one this was a major contributer to poor battery and phone performance. Animated wallpapers are very often poorly programmed or simply over bloated. Not too mention on the severe end of the priority list of needs. All though cool.
I am not over clocking or installing a custom rom on my phone quite yet because honestly the roms are not stable enough as expected this close to birth, and really don't offer any additional functionality that I find very useful as of yet. I am using Tasker to accomplish a few automated switching routines to toggle WIFI and Bluetooth. I am also using Folder Organizer to keep my apps categorized in a humane manor. I am a widget-aholic and have not really found a downside to having too a lot of widgets running.
How much do you use your phone a day?
Not everyone is willing to cut out their social networking. A big part of smartphones now is always being connected. This includes social networking, sharing pictures, sharing locations... some people get into all of this and some do not.
Also, some people like weather updates, stock updates, news updates, etc. Everyone uses their device differently to fit their needs.
I think it is common sense that the more services you use which consume radio/data/processing time then the quicker you will drain your battery.
Thank you for sharing the setup that works for you and affords you such great battery life. I have been having great battery life too. I am currently not in a 4G LTE area, but the device on 3G has been great on battery. You would never know there are any "issues" if people did not post about them!
What is your uptime, display on time, and partial wake usage?
I didn't check that deep in to it, but I had it plugged in to some speakers at work for about 3.5 hours playing slacker radio from wifi so I could rock at work. I used the phone to call tech support for my wifes phone which took a while and other shorter calls through out the day. Right now my up time is about 65 hours, awake time is at 26 hours. Not sure where to get partial awake. My display on timer only says 1 min. But honestly today was not a big phone use day and it sat in the dock on the ride home so all those stats are irrelevant today. But still my battery it at 83%. A lot of people were complaining about there phones dying with no or little use half through the day. So hopefully this brings a little light to the end of the tunnel.

On the bright side I am getting 20mbps down here at school.. SDSU..
4 bars of LTE flies
Do you have it on LTE only mode?

Yah.. I am surfing pretty heavily though.. down to 58% now..
Guess ill have to sit in a different seat for the rest of the classes.. I see power outlets along the walls
It sucks though because on the Droid x, I could surf during the whole 3 hr class and walk out with 50% left.. guess this is the price you pay for this kinda power and speed lol
from 6am to 2pm phone is dead
music for a hour and half while on airplane mode
3g only
gps,bluetooth,wifi off
half hour of web browsing on 4G
about 15 messages on live Profile app
about 40 text messages
auto sync and background data off
One thing I dont understand is..When my phone is idle the battery is still draining.
6am to 6pm...
3g only (off when not using it)
gps,bt, wifi - off
games for about half an hour...
a couple calls
>20 txts
screen at 15%ish
autosync and background data off...
and now i'm at...89%
I have also found that in the first couple of days (2 or 3 days) after a reset... the phone does a BUNCH of funky things. First night after a reset...VZwireless said at 3AM i had 130MB of transfer... not possible - i was sleeping. it wasn't me. but...i did wake up with >30% of the battery gone. I think the background data off is a good place to start...but definitely wait after a couple of days.
I seem to be getting about 36 hours of up time on a charge. Mostly on wifi at home/work. I have 4G turned off as its not available here yet.
Sent from my ADR6400L using XDA App
Ok.. 4 hrs .. done for ... Did make it through class.. 8% left
There will be a patch soon to help with the idle 4G battery drain. Lady on the phone told me its in the works. Either way I just got the extended battery today. I actually dont mind the extra size.
Hmm... whats the anecdotal battery life for an extended battery given these settings? I've gotten to the point of running my display at 5% when indoors ==;;;
Also, I've heard of people getting free or heavily discounted extended batteries.... Any tips for this?
I am using an app called fastbright which really helps with the display battery drain...I just use it o bright when i cant see if i am outside....post #10!!! yay!
I've used my phone a decent amount today and battery is still at 62%. Running Das bamf at 1.2 ghz and screen brightness at 100%

I feel the same way... if you are playing around on the tb while it is pluged in it will take a good 4-6 hours to charge to 100%
Anyone not totally impressed with the battery life of this phone? I actually think the Thunderbolt held a better charge.
I got nearly 30 hours out of the battery, you just got to know how manage the drain resources. So yeah im pretty impressed by that.
How do you manage the Drain Resources?
I use a profiles app,
ex of one of my profiles: when I am at home, I have it set to turn off bluetooth, turn on wifi, turn screen brightness down and the screen is on a short timeout timer. I also have gps turn off.
then there is a "car mode" profile: it turns of wifi, sets brightness to automatic, turns on bluetooth to connect to my vehicle and turns on GPS
Dont leave things like FB and Twitter auto-refresh less than once an hour, I had used that on the charge when I first got it (used it on my X) where it updated 15 every 15-30 mins, besides realizing its pointless, it drained the battery pretty quickly.
now the 30 hours was during mixed use, a few phone calls, some browsing and some app installing and such. I don't expect to get that out of heavy times and definitely not when playing games.
It should also be pointed out that 4G is not available in my area, so I have it set to CDMA only so that it's not trying to constantly find 4G coverage.
My DC's battery-life is significantly better than my TB's. *shrug*

Whats that profiles app called?? Sounds like what I need to get my battery life where I want it
I use MyProfiles, there is a lite version for free and the paid one is 1.99 i think
I get way better life than the Thunderbolt. Even playing with it a lot with the screen on full blast and always on internet.

Damn i almost spat my coffee lol
my TB would die in under 3 hours, im a heavy business user but that was bad bad bad for any phone, my TB would still drain battery while plugged into my car charger while using gps, all the charger did was stop it from dying withing 30 mins lol
loved the TB hated the signal and battery!
The first day I had my Charge it had really bad battery life. The next day (after running the battery all the way down and then charging back up) it was much better, and now it's always like that. It still doesn't compare to the Droid X, but I knew that before buying, and I've got the better screen and 4G.
Using Faux rom (Kernal version 2.6.32.41-CM7-Faux123-v0.2.3)
I was able to get a crazy amount of life out of the G2x! Anyone else able to get some times like this?
When I first got the phone it would only get about 4 hours.
i've been on 11 hours, Nexus AOSP, and am at 85%
With SetCPU and underclocking when idle or on calls?
Is Juice Defender involved?
Exclusively on GSM?
Are Auto Sync and GPS off at all times?
Please provide context.

Yes, setcpu and some UC, phone goes to min processor on screen off
Juice defender set to standard
data set to auto
auto sync gmail, gps only on demand
note today was a very, very light day of use. Yesterday I used it moderately, checking emails, maybe a call or two and several hours of music and was at 50% after about 14 hours.

I have tried virtually every ROM and kernel combination for the G2X and for my phone and usage pattern I have had the best luck when I returned back to CM7, currently RC1 without OC/UV kernels, without SetCPU/PimpMyCPU, and without Juice Defender, or any similar such programs. My gains appear to be achieved by better efficiency with the screen off. The only modification that can be responsible other than CM7 itself is that I have the phone 2G only unless I need 4g at which times I turn it on manually. I think this is the actual cause of most of my better battery life.
Recently I went 32 hours of light usage (maybe an estimated 3 hours of phone calls and 2 hours of actually performing some task in Android) and was at about 35% battery life (although I believe battery percent is totally meaningless on this or any GB Rom for the G2X). I can easily make it sun-up to sundown with moderate to heavy usage unless it involves lengthy playing 3d video games or similar cpu/video intensive tasks.
When I first had the phone (completely stock) the battery would run out before 8 hours even if I didn't use it at all. I think I was getting great battery life with the AOSP ROM (Faux) and Eaglesblood ROM without modification. I am came back to CM7 rather than those others for purely aesthetic reasons.
My conclusions are merely based upon extensive trial and error and subjective impressions. I am not an expert at anything, except perhaps backgammon, lol
2g only is not a fix in my opinion. I purchased a 4g phone for a reason. The software and drivers are still an issue. I get a solid day (12 - 16 hours) out of a single full charge with 3 email acounts checking every 30 min. Surfing the web and a little game play for fun. The screen is the biggest draw on the battery. My battery monitor shows a direct corolation to battery draw and the screen on.

I understand your point, but how often are you actually using 4g. It is not necessary for syncing email or other background tasks, in fact on my phone Pandora runs the same on 2g as 4g. And when you do need the performance of 4g it is 2 clicks away, one swipe to pull down the notifications and another to toggle from 2g to 4g. It connects in about 10 seconds, for me anyway a shorter period of time than it takes me to figure out what I'm doing. 4g appears to be the biggest battery draw with screen off. If you use JuiceDefender you can program it to turn on 4g whenever particular programs are launched.
You are right about the screen it is certainly the biggest draw with screen on. I run a bike computer with gps program. I run it with screen at full bright constantly on, gps running, plus using whatever small amount of use the program uses to operate. At this rate the battery runs out before 4 hours are up.
Oddly making phone calls appears not to drain the phone at all compared to other activities. I've taken my phone of the charger and made a 1.5 hour phone call and hang up and the phone is still at 99%.
23 hours and counting on this charge...
i can get that time on my stock rom one time my phone lasted 1 day 15hrs on stock rom.

I have no doubt, there is nothing inherently wrong with the stock rom as long as you root it and get rid of the bloatware. Getting bad battery life is more a matter of something being wrong, instead of a particular rom being right.
I don't really understand the battery info built into Android, my uptime right now is just over 16 hours and I am at 25%. Which is good as anyone can expect with normal usage. But what is confusing is the usage breakdown, it lists most items at exactly 19%, Cell Standby, Wi-Fi, Dialer, Android System, and Phone idle. Voice calls is the only other item at 6%.
What the heck is Dialer doing with 19% of my battery!?!?
16 hours so far with 20% left.
8 hours of that was while I was sleeping.
While there was some screen-off time for the other 8 hours, the tasks I was doing included redownloading ALL of my apps manually, applying themes, configuring widgets, browsing xda, email, light texting, and a couple short calls.
I am running CM7 with stock kernal. I have like 40 widgets running (probably an exaggeration). I'm running Juice Defender set to disable data/wifi when screen turns off, and enable it for 2min every 15 min. I also have setcpu running. I increased the min to 456 instead of the default 216 because it seems to keep me from experiencing the black screen of death when I leave it higher. My screen-off profile is 456/456, and my in-call profile is 608/608.
Overall, considering that I keep all syncs set to auto so I get instant notifications of gmail and sms, and it takes all of about 3 seconds to turn the data/wifi back on when I turn the screen on, and I don't have to constantly go back and forth messing with 2g/3g. I am extremely pleased with this phone now.
Been unplugged since I woke up this morning...13H 57M and have 40% left.
That's sending many texts, tweets, and using the GPS app for my round of golf today.
currently at 2 days (actually 1d, 23h, 44m) and I still have 30% left. I would say light to moderate use.
Currently running cm7 on nightly 65 with the stock kernal. No setcpu/pimpmycpu or any juice defenders.
