We're going to need more information than that to help you out.
ROM?
Kernel?
Name of "Battery Monitoring" App?
Current Data use?
Signal strength in your area?
All of these will be very helpful in figuring out what your issue is.

Try to be patient, I'm a little new. But here's what I know.
Froyo 2.2
Kernel 2.6.32.9
Battery Monitor Widget App
Data usage isn't high.
I don't know how to find ROM
My display takes 93% but my brightness is all the way down and my signal is always pretty strong.

Im guessing your one the stock at&t froyo. Think about going into the captivate android development section and flash a custom rom. They seem to provide better battery life and are much better than what came with this phone.

You can also disable wifi, bluetooth, and GPS when not in use - that should help.

In my experience the fastest way to better battery life is flash a new kernel. speedmod-kernel-i897-k13e is very stable. Also turn off auto-rotate and auto brightness.

A big battery killer for me is background data and auto sync, I leave it all off, along with the stuff every one else said.

Also, try calibrating your battery.

The only thing I've done to my phone is root. And I've turned off all the auto stuff, I have no idea how to "flash the rom" or anything else.

If your display takes up 93% of battery that's usually a good sign, it means that there's probably nothing in the background sucking up all the juice. Have you tried "bump charging" or replacing the battery? They do tend to go bad or lose calibration if you've overheated them one too many times.

Whenever I charge my phone it seems to get extremely hot. The battery app said like 115° to 120°

Try Juice Defender in the Android Market, made a big different for me.

In my experience Froyo roms have all been garbage battery life *first leak, stock, Perception, Cognition, SuperNova, Phoenix Unleashed* I could never get more then 10 hours on the battery and less with wifi on. Now with GB *perception 2 beta 3*, I get 18 hours with Bluetooth on, Background Sync On, under H *3G*, and the original battery that came with the phone. I am putting up with some of the issues that 2.3.3 has but to me I cannot go back to froyo as my battery life has never been this good Including with jf6 2.1 that originally shipped with my phone.
HTH,
Charlie

I put it on the charger. Only went up to 35c (95f)

While that may be the case, it doesn't always provide for the best signal. You have to test each one and see what works best for your area/situation.

Your battery temp seems very high. You may want to swap the battery before trying other things. Is the phone new? If so, At&t store should agree to swap it out for you.

Settings> Audio> pocket mode off, vibration feedback off, other stuff that might use the proximity and the G sensor off.
Also check your installed apps some of them tend to stay active even after you "quit" them (you can't actualy quit). Download "system panel" for that, and you will see in te left of an app if it uses the cpu Even if an app is there is not actualy draining battery, only if it uses the cpu.
So don't use task killers, they will only drain you more battery.
I keep my screen on auto brightness, and i still get 2 days.
Hope i helped you.

Though I just S-off and rooted but will still try out what you guys say

Leedroid ROM, and unity kernel = awesome combination.
I get really really good battery life
At least much better than stock!

I'm using LBC mod, the newest released version works wonders for the battery!

the max have gotten so far with all the tweaking n stuff is like about 12hrs . . . .is there something wrong with the battery or am i missing something?

I used to have this problem constantly. I'm not lucky when it comes to battery life.
Could be the battery. Try LBC v0.6 and get setcpu. See if that helps if you haven't done so already.
Unity kernel sucked my battery dry.

Have you tried the tiamat kernel? Also, I recommend investing in Tasker to squeeze the most out of your battery. Simply having it automatically go into airplane mode when you sleep helps. Get it (like me) turning auto-sync on for 2 minutes every 15 minutes aswell, and you get over 24 hours battery with heavy use.

On second inspection. Yes LBC is still draining my battery dry. You're not alone. It's beautiful when screen off, but as soon as the screen is on, and its like 1% per minute. Scary.

I had this problem when still on stock ROM and had a few widgets collecting data in the background. It wasn't all that severe though; I had to charge the phone once a day. Since I installed LBC mod, I only have to charge the phone every two days

Use this to track down the battery drain...

And/or this...

If it's data traffic related this'll point you at which specific app is using it...
https://market.android.com/details?id=com.radioopt.widget&feature=search_result
Then either un-install the culprit, or try different kernel, or freeze the sucka using Titanium Backup. See if that helps. Either way, would be interested to know what you discover.
1% per minute is scary drain I agree. Something not quite right there. You're not OC to silly levels are you?

Yes, the new lbc ROM gas a drainage problem... Mine was dropping very fast. Switched back to leedroid, great battery life again! (Stock kernel) I also use setcpu
I reckon it could last me 2 days moderate usage, and 3 light usage!

One Thing Android Sucks At...

even with ICS, is determining how much battery life is left.
I could keep a better tab on my battery life with my watch. It's the worst when it's full and it's empty. It'll be at 100% for 2 hours and 20 minutes later it's at 89%. At the end, when you are at 10%, it's over, you might have 5 mins lefts or 60...who the hell knows.

Very true. I was at 15% for about 20 min but went from 100% to 30% in an hour

I keep my phone very barebones. I use two widgets and I have 20 apps.
When I'm down to 10%, I can have everything off and it will still drop down to below 5% within the half hour.
I've come to the conclusion that Android just sucks at this to ignore the percentages and to keep it as charged up as possible.

On my HTC wildfire with like 5 widget and over 150 apps installed it easily crossed one and half days....

I used to have this issue with Android with past phones like the Epic 4G and the Nexus S 4G. I could be at 70% and reboot the phone and all of a sudden it's now at 52%. I could reboot phone 5 times and get 5 different values. It was all so tiring.
Now i've since moved on to the Epic Touch running Blazer ROM and since i've been on this combo, i've not noticed this phenomenon anymore. The battery guage is spot on. I could reboot a billion times and the accuracy doesn't deviate one bit. Could it be that the dev of this ROM has some super mojo/juju that just works? (I hope so).

Cell standby: AOSP vs. Sense

Okay, I've been meaning to ask everyone about this for a while now. Has anyone noticed extremely high cell standby use in battery stats? The reason I ask is, when I am running a sense ROM it reads right around 5% usage. But when I am running any AOSP ROM, it usually between 35-40% and causes me to get really poor battery life. Has anyone else encountered this? Thanks for any info.

No, i have used both and havent really noticed anythiing like that. It may be just crappy cell signal, what roms were you comparing

I've flashed just about everything available for Mt4g except the ICS ROM's. I'm running team Inferno's arhd at the moment, but have in the recent past tried coredroid, tdj's sense ROM and a few others as well as cyanogenmod, MIUI, and some other AOSP roms too. I get great service in my area, and this has been an issue on all three mt4g's I've had.

I remember someone posting on here about sense or aosp roms, that you could open titanium backup and delete something called "Google Backup Transport" to help a lot of battery issue. I'm not sure if its related to what your problem is though..

Look into getting BetteryBatteryStats (http://forum.xda-developers.com/showthread.php?t=1179809). This will help you figure out exactly which process is draining your battery, as it isn't always Google Transport.
Also, this is a long shot since you said you have this issue on all AOSP ROMs, but have you tried changing the kernel just to see if that makes a difference? I know each ROM comes with a different kernel, but maybe there's a combination of ROM + other kernel that will work for you, instead of the default. I know that was my issue at one point.

On the AOSP Roms I always thought that it was normal for cell standby to be the highest battery drainer in the list because that's just how it was reported for some reason. I could never get the Display's battery drain to be higher than the cell standby. But either way I got the same battery life whether I used Sense or AOSP. The only difference was that AOSP just displayed the battery usage wrong.

+1...I do receive better battery life on AOSP tho, unless I debloat Sense. But the cell standby is always high on AOSP

I've tried most kernels that are out there, and still have the issue. I thought at first that the readings might just be different in AOSP vs. Sense. I usually let the ROM settle in for a day or two to make sure, but cell standby is usually double what display is in battery stats. I can literally watch the battery get crushed. Average battery life is about 8 hours on any given AOSP ROM and close to 24 hours on sense roms. I just seems like it should be the other way around haha. I really appreciate all the help I've received from everyone! You're all great!

Hmm, well one thing is for sure when your on AOSP and your in a area with bad coverage the battery drains significantly trying to connect to T-Mobile. Have you tried putting on airplane mode in those situations? It's what I do when I'm in school because I have literally no service there.

Did you try disabling mobile data when not using it? Or using juice defender where it would turn of data when the screen turns off?
Sent from my HTC Glacier using XDA

I've got juice defender plus. It adds around an hour and a half of life. The problem is, it seems that most of the battery isn't used up by data being enabled, but the phone being connected for voice and text. I'm not willing to shut off all radios for extra battery life because what use is a phone that people can't call you on?

I find that when I have my phone unplugged for like 3-4 hours it drains very quickly once I start using it. For example I'll unplug at like 7 or 8 and go back to sleep, wake up 3 hours later or something. When I start to use my phone it seems to drain a lot quicker. Is this normal for you guys?

Does it drain much during that 3 hour interval? You could try using an app like CPU Sleeper or SetCPU that allows you to turn off a core when the screen is off.

I love the battery life on Synergy 1.3! I haven't flashed to 1.4 yet, kinda liking where my set-up is right now. I'll probably wait until there's a few of the kinks worked out yet.
But yeah, I charge my phone overnight too...It usually comes off the charger about 8am, and at midnight I still have 50-60%, depending on how my day went...Some days, I only have to charge every other...

Looks like you're using about 12-13mA while idling, I am assuming you had mobile network and wifi off? I'm typically at around 24mA with wifi idling

Nope. Data and wifi on although I have sleep set to never when plugged in. I don't think I have anything set to auto update besides push mail though so it probably slept all night with me
This is standard battery as well. I just added the lean kernel and I am getting even better battery life. This is with mild screen time and 2 hours of pandora. You can see in the screen shot that it was only really awake when I had the pandora running.

Crazy battery life.....anyone have comparisons between this and 1.4? Would be interesting to see if the claims by some is true about the additional drain.....

It's lack of apps honestly. I have nothing auto syncing. I'll sync it when I get in the app. Also using better battery stats showed me an app that was wake locking. The lean kernel and battery saver script I'm sure are helping. No need for an extended battery on this baby.
