My battery life sucks.
I even got a new battery from T-mobile free, thinking my battery might have been defective or used too much already. But no.
My battery usage seems to be DOMINATED by the display - ~80% vs like 5 or so for cell standby. Is this normal? I have auto-brightness turned off, and brightness set to the minimum. Timeout time of 30 seconds.
Currently running Bionix Final with JAC's OC/UV kernel, but I had battery issues on Franken-Twiz, Hybrid, and stock as well. (Also all combinations with stock kernels.)
I use it quite heavily and real display usage I get about 4 hours

Just wondering because right now I'm using GSB v2.6 and I'm getting max 6 hours of battery life through normal use like checking email, sms, casual browsing, and listening to music.

Have you tried re-calibrating your battery? Made a huge difference for me; it's good to do especially with a lot of ROM flashing, but even with just one it can throw your battery calculations off.
FYI follow the instructions to the letter, otherwise you might as well not do it at all IMHO.
I had the same issue using GSB 2.X. Switched to OMGB 1.1.1 and i now get 15 hours with moderate usage and no tweaks.

I've gotten over 30 hours before with GSB, immediately after a recalibration.
Your best bet for battery life is setcpu settings. As long as you're using froyo and gingerbread you'll get a boost.
I suggest Tazz as his ROM's have always worked for me. My setcpu sleep profile is:
min 19mhz
max: 480mhz
governer: smartass
and in advanced settings I have:
polling interval: default
Whatever the next one is: 98
Ignore smart or hwatever the third one is: 1
bias: 4
edit: With this I can get a good day or two of moderate use.
I found on GSB that that 19mhz is too low and the phone does not always wake from sleep. I followed workshed's suggestion of min 480 mhz with max 710 using CM7's CPU settings and all worked very well...that is until 2.0 when battery life went to hell. I recalibrated but i think the problem was my exchange mail app.
Oh, and with smartass you shouldn't have to set sleep profiles. Supposedly it's "smart" enough to figure that out
You can also try collins battery tweak, I use it on tazz gingerbread and it works awesome my phone used to die pretty fast before I tried it and now that I put it back on my phone I am very glad I did.
Im running GSB 2.8 but for me, all seems to be going well.
In one day, off a single charge, I've gone 12-14 hours at a time!
Make sure you always charge correctly, and don't abuse the phone's battery all the time!
Been trying out various ROMs and lately, I've settled on FroShedYo's Final V11 with CM6.1 as my everyday workhorse, stability over speed, and with a bit of battery calibration - getting an average of easily 20 to 30 hours off a full charge on OEM 1500 maH battery originally for the HTC Ozone (so it's about 15% higher capacity than stock's 1300 maH, which I keep as a spare/backup.)
With a bit of tweaking on CPU clocking (Ondemand), turning off vibrate & alert sounds/LED's, and email checks every 60 minutes (1 account only + Gmail pushed) and minimal widgets open, etc. - I can leave the house at the beginning of a long day, go about daily business, voice calls, check email checks, quick news & weather update, etc. and still have 25% to 50% battery life after an extended 12 to 15 hours day on the move, depending on how the device is used. I get a poor 3G signal at the house flipping to 1X often & back, and wifi OFF on the road (BlueTooth ON for driving but no Maps/NAV (ON at home.) In short, plenty of variables on how the battery is getting drained - in standby mode, clock speed is lowered so I could still be over 90 to 95% battery after 2 years but it will slide downward with active usage. After wiping/flashing & reinstalling all the APPS & fine-tuning the settings, I do a NAND backup and then do the battery calibration - and after 1 full cycle, I've been consistently getting these standby & usage time - which I can live with (C2C flashed and extra goodies on a 16GB SD card.) Yesterday, it was showing over 50% after 15 hours of light/moderate usage.
I've tried the latest nearly finalized GSB/GB Roms & variants, they are faster & fancier, but FC's, GPS issues & other minor bugs plus "not as good" battery life had pushed it back to 2.2 OS on the Eris. OMGB 1.1.1.1 and the Condemned CM7 just out this week are pretty cool - but battery life really slide quickly - unlikely to see more than 10 to 15 hours of usage out of a standard/non-extended battery.
The other one that I like is the Nonsensikal 2.2.1 ROM, troublefree, stable & reliable - the edge on battery yielding to FroShedYo's version ( keep that on another 8GB card along with the newest GB releases for "playing")
Otherwise, the xtrSENSES 5.x and xtrROM 5.x are fine as well for everyday use - performance & battery life-wise over the latest stock 2.1 ROM.
Those are my two cents for what it's worth, great work being done here and it's giving new life to the Eris, not quite EOL for some of us - played with the TB in the store, nice big screen & fast, but I'm not about to wear a "brick" phone going out on the job with an extended/bulky battery just for bragging about 4G/LTE. Mobile devices have come a long way, I still got my original analog MicroTac XLT with a 2200 maH tipping the scale at 10 oz in my bottom storage drawer.
On the sideline for a "polished" GB/GSB ROM with the bugs resolved and better battery life, and I'm off to flashing it on my spare SD to test it out. for the "adoption" usage.

6 hours wow thats bad man. i get 30+ running gingertazz
i leave 3g off till i need it and usally just use wifi if around wifi spot
do a recal. like people suggested
So my settings aren't anything unusual on my tbolt, but right now my battery usage reads as follows:
3hr 36 min since unplugged
82% Android system
5% cell standby
4% voice calls
4% idle
3% display
There's a laundry list of items under android system, and I'm in a pretty poor signal area. I always though signal-searching went under cell standby though, is that correct?
Additionally, when my e-mail accounts sync, I always assumed that would go under cell standby, but there's something in system for syncing as well, would it go there instead?
thanks for the help
*edit - battery died after 6 hours of almost no use. phone was also getting quite warm. I also want to point out that this doesn't happen normally and I've only noticed it a time or two in the past.
What ROM and kernel combination are you running?
lean kernal and das bamf 1.5
I would backup your applications and data, then reflash the ROM and see if you are getting the same results on a stock kernel.
I was using leankernel too and got this same problem. Or rather, as soon as I flashed lean kernel, I noticed that my phone would die quickly in standby, regardless of what speedtweak.sh mode I was in. I was getting something like 4-6 hours of light use out of my phone with before it would die.
As soon as I switched back to the stock bamf 4.4.7 kernel, my battery went back to normal, draining to 30% battery after 10 hours of light use.
I don't know why, but the ROM and kernel just didn't play nicely for me. Try reflashing back to the stock bamf kernel and see if it helps.
I gotta say the newest version with the kernal is INSANE. I'm getting 6 hours of usage that drains 20% of battery at 1400 mhz. Of course brightness is at 1/3 but its nothing that bothers me.
So I'm wondering when making phone calls that's the #1 battery drain second to the display maybe even more.
IS there or will there be a kernal or rom that locks the phone at 245 mhz and prevent data / screen usage while on a phone call?
(This would truly help the thunderbolt considering the battery is HORRIBLE )
I'm on BAMF 1.7 stripped, and have not looked at CPU speed or anything overclock undervolt yet, and with an extended battery I stayed at 100% for 20 minutes this morning, and after 45 minutes of searching apps on wifi, have 98% left still! It's amazing!
Yesterday after work I had 75% left, and I did about 30 minutes of 4G surfing, and a couple hours of on and off wifi surfing. It took 3 hours to recharge last night connected to my computer, so it's possible the battery is being reported incorrectly. I'll just have to run it to death today to see!
I cannot answer your phone or display question as I have only used 7 minutes of phone in over 2 months, but my display is at 70% with a 1 minute timeout.
So far, I love this ROM!
Yea Its amazing how a rom and kernal can make a phone operate 200X's better than the actual phone developer themselves. Its kind of pathetic on HTC's side.
But can anyone confirm a rom/kernal that lowers cpu usage /display and data while in a call to save more battery?
Or entirely like crap if you mess something up. It's more about settings than anything else.

I have (finally) just made the jump to CM7 and have been absolutely loving it (MAJOR props to the Devs for it).
Anyways, one thing I have noticed is that the battery drain when the screen is on 'feels' like it is faster than it used to be on deblurred roms.
I am running Faux's 1.3 ghz overclock kernel (.2.1) and have it moderately undervolted (as I am still getting a feel for undervolting in CM7).
On my previous rom, Alen v4, I was running the same version of Faux's kernel (obviously not the cm-specific one), and was undervolting as well (though to a lesser degree, as it seems that CM7 is better for undervolting). I never timed the drain on this rom, but I could have sworn that I got an hour of screen time for every 10-12% of the battery.
Anyways, the battery seems to be draining at about 1% for every 3-4 minutes (average time over a 10% period was 3 minutes, 40 seconds per percent) of screen-on time when I am only using it lightly (I was reading the news and browsing Facebook a bit during this time).
My drain when idle seems very reasonable.
Does this seem abnormal, or am I just being overly paranoid about battery life?
In practice, I think this is still going to be fine, as I never have the screen on for more than two or three hours in any given day...I am just curious as to how the drain I am experiencing relates to anyone else's.
Thanks!
(and yes, my battery is fairly well calibrated. Was 'fully charged' this morning at 99% at 4169 mv...not perfect, but still solid).
Edit: And yes, I know I am breaking xploited's fifth rule of battery life...
The only thing I can think of is that you are overclocked all the time.. or have something running in the back ground all the time.
