I recently got into rooting and flashing at the end of last year. This site has been a great resource for how to's and learning about the ins and outs of phone hacking.
Anyways, here's the background info: rooted using Unrevoked Forever, s-off, stayed with stock ROM and kernel only using SetCPU profiles. When I was on stock software, I had unbelievable battery life. I'm a light user (~10% awake time) and rarely beat on the battery -- light calling, email, texting, Facebook, random messing around etc. Anyways, when 3.70.651.1 came out, I knew that was my chance to flash my first ROM.
I flashed SprintLovers and got decent battery life, but nothing compared to when I was running the stock ROM. I then tried almost every variation of Netarchy's non-SBC's CFS 4.3.4 kernels -- more HAVS, less and no HAVS. No dice. I've tried with and without setCPU altogether, along with and without setCPU profiles but using the smartass and conservative governor. I always set the processor to 245-998 and never overclock.
I liked myn's Warm TwoPointTwo, so I recently tried that last week. Again, I'm getting okay battery life (~1.5 days) but with the usage I'm at I'm pretty sure I should be able to get 2 days easy. So I tried flashing Netarchy's 4.3.4 non-SBC CFS kernels with the same results. I've also tried with and without setCPU, along with and without setCPU profiles. Finally, I gave up and I'm currently using Netarchy's 4.2.1 cfs havs more smartass and using setCPU.
It's definitely not related to PRI 1.90 as I'm not getting the 100% partial wake time in Spare Parts, and I know the consensus is divided as to whether or not setCPU interferes with HAVS. I know all phones are different and ROMs and kernels interact differently on an individual basis, but I would really like to stick with myn's ROM and a good kernel to max my battery life. rather than go back to the stock ROM. Any suggestions on extending my battery life before I shamefully reflash back to stock software? I always do a full data/cache/dalvik before flashing a ROM, and wipe cache/dalvik before kernels.

charging USB = 245-998 smartass priority 94
Try recalibrating the battery. Charge to 100% and leave it on the charger a little longer. Then turn the phone off and boot into recovery. In recovery wipe battery stats - in Amon Ra it's under the wipe menu. Boot back up & use the phone normally until the battery drains completely, without charging the phone at all. Some people say until the phone turns off on its own, but I'd try to avoid that. Just get it as low as you can. Then once it's dead, charge it fully without breaking the charge until it's completely full. You should see an increase in life after that. There's also an app in the market that clears your battery stats. I believe it's called "Battery Calibration", but I could be wrong about the name.
Since you don't use your phone much you'd be a good candidate for undervolting. If you don't want to undervolt while the phone is in use, just use a screen off profile only. Turning radios off while you don't have a signal or you aren't using them will make a huge difference as well. Let us know how it goes

I've heard people recommending a battery calibration after flashing a new ROM. My battery has seemed to be jumping down a few %ages and then stabilizing for long periods of time at a single level. Perhaps this is what I'm missing. I'll give it a try tonight when I recharge and see if that helps. I may try undervolting, but seeing as I got great usage on the stock ROM with the same CPU range I'd like to stick with 248-998. I always have a screen off profile though (as noted in my first post). I've also heard about people shutting off radios and such but I don't think I'd want to take it to that extreme -- maybe if I get desperate enough to eek out that much juice I'll give it a shot.
Bonus: to alleviate my problems at home since I have terrible reception and I know that eats the battery, Sprint is shipping me an Airave free of charge! In the process of trying to contact Sprint's CS (*2 on the dialer), the phone was force closing *1 and *3 work fine, as does normally dialing so I guess the problem is only limited to *2 (I even rebooted and am too lazy to reflash just because I can't speed dial a number I rarely call). Hopefully with your suggestion, I can get back to insane battery life
Don't know if this will help you out at all, but here's my setup...
myn's Warm TwoPointTwo (RLS5)
Net's toastmod-4.3.4-cfs-havs-more-sbc
Launcher Pro Plus
SetCPU:
Screen Off: 128 max, 128 min conservative
Battery<101%: 499 max, 128 min conservative
MinFreeManager:
Set to Aggressive
Twitter, Flikr, and assorted useless (to me anyway) apps frozen with Titanium Backup
Unplugged at 0700 and as of 2205, my Seidio extended 3500 battery is STILL at 74%
Average usage day, with tons of emails, and SMS/MMS messages. About 2 hours of web surfing and 3 hours of Pandora, but not a lot of phone calls today though. About 7 hours spent on WiFi, the rest on 3G (No reliable/stable 4G near me yet).
Background data off
Auto-sync off
Enable always-on mobile data off
I have noticed this is the best battery kernel I have tried out of all of Netarchy's (ymmv). I've had this kernel for 2 weeks, and getting 2 days out of it with HEAVY usage is no problem. I only lost 4% of the battery from 2300 last night to 0700 this morning with the phone sitting on my nightstand.
It seemed to not last as long at first until I wiped battery data and started from scratch. Always a good idea to wipe battery data when swapping ROM's and kernels I notice. Also read (here, of course) that new kernels have a "break in" time of a few charging cycles until they settle in.
Overall:
Completely satisfied with this setup. ROM is lightning fast, and battery is a non-issue with this kernel. Only ever so slightly laggy when opening Handcent or galleries (when I add pics and albums have to rebuild the thumbnails), but what the hell, it's only running 499mHz! Even fired up Avatar from my SD to check for stuttering, clipping, or audio lag. There were none!

OH!!!
Almost forgot!
I stumbled across this "trick" a while ago. Not sure if it ACTUALLY works, but at least to me it does.
It's called "Super Charging" your battery.
Charge with phone on until green light signifying charging is complete comes on
Disconnect charger
Shut off phone
Reconnect charger
Amber charging light will come
When amber changes to green, disconnect charger
When Green shuts off, reconnect charger.
Repeat process
I was bored this weekend, and did it for 4 hours continuously. Yeah, that is truly bored!
I had charged it so much that upon disconnecting the charger, waiting for the green light to go off, then reconnecting the charger, there was NO amber light. Straight to green. Tried it a few more times, with the same result.
Did it actually "supercharge" the battery? Who knows?
Did it take 3 1/2 days of use to break the 25% remaining mark? Yes it did!
So if you are bored, I mean CRAZY bored, what the hell! Give it a shot...

Thanks, but not willing to step into the realm of SBC kernels. However, I will try to go through a few charging cycles to see if my current NA kernel just needs to get broken in. I've also tried the charging method you stated above and while I did get good results, I'm unsure as to whether or not this is overcharging the phone so I decided not to do it again.
Anyways, I wiped batt stats last night after getting the full charge, so still on the drain and need to recharge to 100%; will report back after I go through a few cycles of charging.
Why not an SBC?? Because it fully charges your battery closer to 100% than a non-SBC?/
And don't buy into the hype of exploding batteries. That was handful of cases, that a) were all reported in the earliest days of SBC development, none since and were never fully attributed to the SBC kernel.
Also, you people that say drain til it dies, you DO realize that HTC STRONGLY recommends NOT doing that. According to HTC, you shouldn't recharge until you get below 50%, and no, I'm not gonna go look for the links, use the search feature.
I have a good method in my signature. Give it a try.

Can't argue with a battery that stays at 100% for 3+ hours then slowly drains versus unplugging it at 100%, blinking twice, and seeing 90% remaining...

Well, I'm no developer but if Netarchy says to beware in his latest kernel thread, even if for liability reasons, then that's good enough for me to stick with non-SBC until an SBC kernel is proven to be 100% safe. I think that's a perfectly valid justification to not use SBC for now.
I keep forgetting that we're not supposed to completely drain the battery. I guess I'll recharge when I hit 5 or 10%.
I'll take a look at your thread when I get a chance.

All threads (for the most part) say that, even ROM threads about not being liable if anything happens to your phone. Not even flashing a ROM is 100% safe but you do it anyway.
I've been using SBC since it was being tested the first time and I've never had one issue. No batteries have exploded, no chargers bursting into flames, and no phones have self-destructed.
If you want really good battery life, good performance, and want to try something other than Sense, CM7 and MIUI are really good ROMs. I would recommend Tiamat kernel (use 3.3.8 for now, 4.0.0 has some issues) and make sure to wipe batt stats and do a battery calibration. For good measure, you can try my BSM mod in my sig for even better battery life.
kings kernels are awesome!! im using one and is giving me 30 hrs!

Yes, all threads use the release of liability clause, but NA specifically states in his most recent thread that SBC could potentially cause problems.
Gosh, so much peer pressure! I'm not saying I won't ever go to SBC, just when I feel like it's a bit more stable and all the kinks are worked out. Kind of like you probably shouldn't buy the first model year of a car since the chances of running into glitches is much higher than if you waited a bit for the bumps to get smoothed out. If I'm being paranoid -- well, it's all in the interest of my $200+ phone. Regardless, I appreciate all the replies.
I've heard about MIUI here and there. I guess I've stuck with Sense since that's all I've ever known, but maybe I'll start branching out to AOSP and MIUI. Does CM7 have full functionality now on the EVO?
I'm on my first recharge since wiping stats and it's the fastest recharge I've ever seen. Maybe I do need to just break the kernel in?

My phone is really starting to piss me off. I've had this thing for a damn month now and I've had one goal-to achieve battery life to get me through a typical day and have a solid working device that I can depend on.
Do I have that? Hell no.
I'm getting force closes on Gmail, com.htc.bgp is sucking resources according to the Watchdog giving me alerts constantly about it.
According to Current Widget my screen off mA is about 80-100 which I know is ridiculously high. When the screen is on it's close to 440-500 mA.
I have netarchy 4.2 cfs-bfq-more-smartass and according to the kernel testing webpage, those numbers are way too high for this kernel. I'm on Myn's RLS 3 also.
I have the newest Lowrider theme flashed.
Mobile data is not set to be always on.
Background data is off.
I don't know what could possibly be wrong? A rogue app? Something is just not right here.

Well, right now my up time is 7 hours 44 minutes and the awake time is 1 hour 42 minutes. I have 29% battery remaining and phone has only been off the charger from a full 100% charge for about 8 hours.
I would like to have between 15-20 hours of Up Time and about 5-6 hours of awake time.

Try switching your governor to conservative in setcpu. but for screen off, make your max the option right above 245 (i cant remember that number..i think its 384?) and the min 128 and set that governor at smartass.
For your advanced options, keep the top box at default and make the next boxes this:
95
45
0
15
How do you charge your phone? USB or wall adapter?
Okay I'll try that but I don't think that it's SetCpu...because I uninstalled it and everything was still funky even after a reboot. This is really pissing me off.
Well I'm not saying setCPU is the problem because it hardly ever is. But with the conservative governor, things should be a lot better based on how it deals with the underclocking.

Yeah but I still have the issue of having high power draw when the screen is off. I just don't think that the CPU is sleeping right or the phone itself. I just want to figure out what is wrong here. Could the theme maybe be the reason? I don't see any reason as Watchdog isn't reporting any apps to be high CPU consuming.
Does Lookout Mobile Security tax your battery?
EDIT: I always use a wall charger, the stock one that came with the phone.

You're not the only one. I'm right there with you, bro. I went from Fresh to Azrael, and I've got the same battery suckage. I blamed Lowrider, too, but that's not it.
I noticed at one time today that I spent 39% of my time searching for the Sprint network, which I know is complete crap.
I keep 4G turned off at the office, where my signal isn't great, but I know it's better than 39%.
Some app is eating my battery, and it's gotten worse since I flashed the latest ROMS.
I'd try looking at your logcat to see if there is any unusual errors. It might bring out what is wrong.
However, I have to ask, have you tried the battery fix? I'm getting around 24 hours with moderate use, my average screen off mA is about 90.
What exactly is the battery fix? Just calibrating the battery?
Get this ****, now my computer isn't recognizing my phone. It's saying "USB device not recognized"
Have you tried wiping your cache and dalvik? It sounds like that or possibly your system files have been corrupted. If wiping doesn't work I would try flashing another copy of your ROM.
Maybe you have a faulty battery. Maybe it's the kernel not placing nicely with the battery. Anyways, you can't really get mad at the phone when you're running homebrewed/dev custom roms and kernels that don't come standard on the device. Have you tried running it stock and seeing if you still get the same results?
With the USB disconnection, have you tried these solutions from here

Man, those settings are strait. I've tried every kernel under the sun, Myn's rom with netarchy's Nohavs, and Collins battery tweak, which I installed correctly and took, nothing worked. I had even used setcpu, and it didn't work. I then applied these setting and my battery life has tripled. Thanks!

screen off ma doesn't seem ridiculously high.
in my readings and experience (i am maintaining 6 evos between family and friends! ), poor battery life has usually been a result of leaving mobile data always on, a "rogue" app, bad rom flash and/or a kernel that doesn't play well with the phone. rogue app and kernels are usually the culprit though.
have you tried flashing a rom and not install any apps? that would help you determine if it was a rogue app.
to determine if it's the kernel, try a safe kernel like htc #17 which also idles great. the newer kernels are much more "selective" on which phone it will run properly on.
(i find your sig ironic)
okay i have alot of thoughts and questions on the htc evo battery life. first off i think the devs have done a great job with improving it but in reality we aren't there yet IMO. i mean coming from the hero after calibration and a 1750mAh battery i had what id call good battery life, even without the use of custom kernels or setcpu. even with calibration on the evo, the bottom line is the battery life sucks ass. i cannot even believe htc released a phone with such ****ty battery issues. ive even seen posts on here from people with extended batteries with crap battery life as well.
number 1 they should of shipped it with a higher capacity slimline battery. if it weren't for the devs here the phone would be unusable as i can remember the first time i bought the evo in july i had it for a week and got rid of it the battery was soo bad.
then we have battery mod scripts like calkins & the colin tweak that honestly never did much for my phone. then of course the much debated sbc mod that alot of people says created issues. my own take on it is it seems more of a visual effect or placebo than anything. yes it seems to hold a charge a bit longer but only when the phone is not in use. whats the sense of owning a phone such as great as the evo but be afraid to use it at all?
the reason i do not use sbc is because something to me doesn't seem right about the way it charges the battery. for example: my phone had 88% battery left before i flashed the sbc mod, then after reboot it was back to fully charged? how the hell can that be possible?
so im sorry for venting but sometimes i think i may look into a smaller android phone such as the optimus s or another hero. does the evo shift have these issues as well?
so now i ask for advice from the users that "claim" to get well over 24hrs battery life on stock batteries. im running myn's rls4 rom with the netarchy 4.2.2 /less havs/ no sbc kernel. if i choose to use setcpu and do not want to overclock what settings should work best? or did i hear that havs & setcpu do not play well together?
thanks for listening!
My biggest issue is that it's very inconsistent. I'm on MikFroyo 4.3. When I flashed this ROM I upgraded to all the newest radio, PRL, PRI, etc. It used the stock HTC #15 kernel and I was getting OUTSTANDING battery for the first 5-7 days. Then, literally overnight, my phone started losing 10% of its battery per hour while NOT IN USE. And, no, it wasn't the Up vs. Awake issue, I hadn't installed any new apps, none of that. So I "downgraded" PRI to 1.77 and STILL, absolutely horrible battery life. I've tried different kernels but nothing works. I can take my phone off the charger at 5am and be down to 15% battery by noon with LIGHT use. Signal strength isn't an issue either. It's just frustrating. I understand that these phones have large displays and constantly multi-task but you would think HTC would realize that these phones are going to be used by "power users" and plan ahead for it. But I suppose if our battery wasn't an issue we would just find something else to ***** about all day, lol.
Try miui, that rom gives me the best battery life I have ever seen.

+1. I get better battery life with my EVO running MIUI than I did on my Motorola Renegade clamshell phone, and probably twice the life I got with my Hero. I replace my battery with a charged one every morning and I generally still have 50-60% life left when I do that. I have gone 2 full days on a charge. I did not get this kind of battery life out of any sense ROM I have tried.
You say, MIUI, I say CM6 or 7. All depends on what you like, really in regards to ROM.
I can say that I do get better battery life on CM vs something like Myn's. My phone does stay on for more than 24hrs with somewhat light usage. That means the display is on for about 2-2:30hrs in that time while I browse the web or look at videos, but the rest of that time, it has all of its radios on and is constantly pulling down updates for Twitter, FB, NYT, and Yahoo Mail.
I haven't had any sudden drops in battery life, but if I did, I'd probably buy a new OEM or near-OEM quality battery to replace it.
My BB Tour used to do far less and yes, it lasted longer, like days without a charge, but it didn't have all this stuff going on. So yeah, comparing this large bar phone with its huge display, on-going processes is sorta unfair.
That said, I do wish it lasted 2 or 3 days with light usage.

Coming from Myns rls 5 to cm7 both with stock kernels I could honestly say I see better battery life wit no OC on the CM7 rom. From my experience using warm 2.2 roms, I could get nearly 40 hours on the phone but in order for that to happen I have to barely use it. Which basically means its pointless. I mean if that's the case I might as well leave the phone turned off. Not to mention how much of your time that gets consumed searching for the perfect kernel to fit to your liking and phone.
I really do think the battery sucks on the evo but there are ways and roms to make it manageable. Sooner or later the new duel core & Tegra processors will be here soon, so bad battery life should be a thing of the past. Only because the CPU wont work so hard while sharing the strain we put on are phones. Lets just all sit tight and let technology take its coarse.
r0cky.Da.3v0.SU.-
+1 for MIUI. This is the best battery life I've ever seen. To the point where I stopped carrying my charger around. I still keep and extra battery just in case but I haven't had to use it in weeks. I get through the day easily on a full charge and I have no problem charging mine at night...I've been doing that since back in the day with flip phones. I thought everyone charged overnight while sleeping or is that not the norm?
Its also a norm for me if it needed it. Another reason I think MIUI and CM Roms are good on battery life is because ultimately they don't have 4g. I've been on the same charge all day and I still got some juice left to flash the new nightly for cm7. U gotta love it.
r0cky.Da.3v0.SU.-
Doesn't CM have 4G now? Even when I was on Sense roms I rarely ever used the 4G though. Same here though, I took my phone off the charger around 3pm, got home from work around 4am and still had plenty of juice left to back up, flash the new MIUI rom, and set it up. Seems like battery is getting better with every new release. No complaints here.
I don't get 24 hours battery, but I don't lose any battery while idle on a sense rom either. I'm on mikfroyo, with net's 4.3.1 cfs havs nosbc kernel. I'm using setcpu, and my screen off profile is 245 min and max smartass. With the screen off I barely lose any battery at all. I charge my phone periodically throughout the day, but I've gone 10+ hours off charger (with moderate usage, but no gaming or anything like that) and still had a good 40% battery left.

Keep in mind these phones have 8mp cameras, 1ghz processor and tons of extra memory. Basically the equivalent of the lap top computers of 2 years ago.

Honestly anything over eight hours is descent especially if u still have juice left over. Even with that said and speaking for all the cm users, I can honestly say that netarchy kernels are definitely not needed using this rom. Even though its a great kernel, That would be kinda suicidal towards my battery life.

Yeah, CM6 has wimax but CM7 doesn't. On the account of the Rom isn't stable yet.

netarchy-toastmod 4.3 cfs-nonhavs-noUV-sbc is what i want to use on my phone, because i heard it was good for my siedeo 3500 batt.
my question is is this a stable version now?
do i still have to downgrade nv and pri?
I am using stock htc 15 now and know its not charging my batt all the way
I have tried a lot of kernels already just not this one and I know I could buy and external charger or use a backup batt. but if this kernel works that would be great, I know I don't want HAVS or colin batt tweak.
So what do you guys think is this a good kerenl? is it the best version without havs. and will it charge my siedo 3500mah batt.
Thank You
btw im using mikfroyo 4.5
I don't think 4.3 was ever a "stable release," the stable is 4.3.1. I have run that kernel with no issues, but I mostly use 4.3.2 CFS or Ziggy's 012111. You're going to get mixed answers on sbc though. I have excellent results from following these instructions to get my battery to last longer without using SBC:
1. Charge till at 100% and the light turns green.
2. Unplug until the light comes off and turn off the phone.
3. Plug the cable in until the light comes on and turns green.
4. Unplug until the light goes off
5. Repeat 4 and 5 a total of 10x
If you do that, your battery will stay at 100% longer. Mine took about 15min to loose 1% the first time I did it.
You might also want to boot into recovery after the first time you do this and wipe battery stats, then let the battery run allllll the way down. After doing this, even if you don't do the above every time, it may drop initially once off the charger to 95% or so, but it should last MUCH longer on idle. But if you want it to last longer at 100%, you have to follow the above steps.
I have gotten about the same results with most Kernels using this method. Net's are certainly good, however, no one can tell you what kernel is best for you as every phone is different. I would dl a few different versions of Net's (4.3.2, 4.3.1, 4.3, etc) in whatever config you want (no havs) and start with the newest one. If that doesn't work, go one version older and stop once you find one that provides performance you're happy with.
Sorry if any of this doesn't make sense. I'm tired and I have been proof reading crap all day so I'm not about to read this again.
thank you for the fast response if i would've just read better i would have relalized that 4.3 wasn't stable it even said it on the link lol. Anyway I installed 4.3.1 sbc-cfs nohavs and am now charging up i got 31 hours on htc15 with my 3500mah and now lets see what this kernel lets me get.
anyway will post back my results
system is mikfroyo 4.5
kernel sbc-4.3.1 cfs nohavs
sideo 3500mah batt
setcpu with 1113mhz max and 128 min
screen off profile only(set at 245mhz max/min)
380mb of system space and 7.30 sd card space
monitoring batt with battery monitor widget with alarm set for fully charged.
newest radios and nv/pri(do i downgrade to 1.77pri/nv with this kernel?)
any way charging now will post results when battery is almost dead with screen shots and prolly a youtube video as well.
4.3.1 are considered stable releases that i am aware of
Where can I find the net sbc kernwels
go here and click on the sbc thread link at the very first post and choose the one you want it starts with beta and more towards the bottom are the stable ones.

@op, i'm curious, why the need to overclock? What are you using that actually benefits from this?
I'm actually underclocking @ 921Mhz to achieve a bit more batt lift (same battery).
well its not a high overclock and just to increase speed of loads and surfing a bit, I bought the extended battery so I can actually use it.
Been Runin kingdom for weeks now had no issues til yesterday my battery started burning up the entire back of my evolution is very hot and i only get bout an our of life. I uninstalled all resent apps and haven't changed the way i charge the batteries. Any idea wnat's goin oh?
Your battery is fried.
it could be the kernel u used. I heard some cases where the sbc kernels were making the batteries smoke and basically garbage after that

I got a good laugh out of that.
Though, if you were using an sbc kernel, guilt right there; or your battery is toast.
Love the stupid replies but its not the kernel i use a battery wall charger i never charge via USB
did you ever let the battery fully discharge?
i killed a Li-on battery on a laptop by always plugging it in and never letting it discharge.
now it only lasts about 10 minutes and dies when i unplug it.
Usually let it discharge to about 6% its multiple batteries and just started happening.

Well the appropriate percentage to discharge is 5% because anything prior will only make your battery burn up and make the back plate hot and only give you 10 minute battery left thereafter. - see this explains all. close thread please.
Okay, so what it really sounds like is a case of a bad battery. Sometimes you just get those and you are the lucky person at that.
The mention about SBC kernels and the battery issues were even case-by-case at that. There were no proven conclusions but only hypothetical scenarios at best. I'm not discrediting ones who experienced it but just channeling logic.
For your matter, you do realize that the Kingdom ROM is never going to be 100% stable, as mentioned in the OP, so there could have been a freak instance of it not agreeing with your phone. The inevitable truth is that even if you and I have the same phone, same hardware, there are still small differences in parts sometimes and even those make one ROM or kernel agree and disagree with each of our own.
In short, I believe that it's best to go buy another battery in this case since it just sounds like you're going to need one anyways. As for the cause, it's hard to say because none of us really know your entire hardware build, kernel, applications used, and any other variables that could have caused this.
Here's a link to a ebay listing for batteries:

If ur using a SBC kernel it doesn't matter how u charge ur phone. It would happen with wall charger or computer charge
Kool-aid anyone? I hope you people realize that the Kingdom ROM does not have SBC. Also that the hottest running components are right under the battery. Just from what the Op posted it sounds like the phone is heating up off the charger, and getting only a hour of battery life.
A number of things could cause the overheating condition. From an app grabbing the CPU and locking it at 100% to having the 4G radio on in a no-signal condition. The battery will also get very hot if it has a high load put on it as well again pointing to something other than SBC going awry. I would suggest that the Op do a complete wipe, and reinstall the ROM. Then install Battery Monitor, OS Monitor, and SeePU (to monitor the CPU activity).
Battery Monitor can keep track on how your battery is being used as well as the battery temp(and you can set a high temp alarm as well). SeePU monitors CPU, and network usage in real time. OSMonitor is a process monitor (much like top/kill in *nix, or TaskManager in Windows) so you can see, and kill off a runaway process.
Hopefully this is a bit more helpful.

Thanks i will look into it. Good to see someone trying to help instead of just trying to feel superior. To everyone else i know what SBC does and i know I'm not using one.
SBC doesn't make batteries explode...more times than not you have bad battery

I've about had it with my EVO 4G. I can barely use the thing before the battery is down to 30% or lower. When I first unplug it in the morning, I'll browse reddit or XDA for all of 5-10 minutes and my battery will go down to 75% easily. I've tried tons of ROMs (running Energy w/Shooter Anthrax kernel as I heard it got amazing battery life) I've tried resetting the battery stats -- i've tried unplugging and replugging in the phone multiple times when the charge light is green, I've tried just about everything I can find on here dealing with battery issues and to no avail! Listed in my battery stats the only thing that's ever high is my Display usage but even factoring that in should I really only be getting an hour or two of mild internet usage before my battery is completely depleted? I can barely make it through a 6 hour work day (checking texts on breaks, light internet, maybe a 5 minute phone call) without having to recharge it in my car.
I'm open to ANY suggestions short of buying a new battery -- sadly it's not an option at the moment.
Do you keep 4G on? That drains a battery like nothing else if left on. Same with GPS, especially in Sense Roms for some reason.

i recommend using a aosp rom if battery life is a MUST. I would suggest you use Decks aosp rom with CoD tweaks Tiamat 3.7.7 and vipermod and underclock to 500 on smartass governor........all this is what you should do if you choose decks rom
Make sure your 4G is off, but Evo is known for its horrible battery but thats ridiculous. Try a new kernal to adjust to CPU settings. If that doesn't work, you might need a new battery. Evos are know for having their battery fried easily, mine fried and I had to get a new battery. :/
You should definitely make sure your 4g, Gps, Wifi, and blue tooth is off. If that does not work I would strongly suggest you downloading Cyanogenmod 7.1. When you aren't using the phone under clock it and do medium speed when you are using it. I last around 8-9 hours doing this. Hope it helps.
Okay I installed Decks Evo GB rom and the Tiamat 3.3.7 kernel. I followed the guides but couldn't seem to do the undervolting correctly with the apps i was provided...but i'll do some testing and report back!
Can someone point me in the direction of the right app for undervolting and whatnot?

vipermod is used for undervolting http://vipermod.tiamat-dev.com/vipermod-voltage-control/
Also, it could just be that your battery is tired. Is it at all swollen, in the least bit or rock hard? It should feel firm, but give a little.
People tell me all the time, "my battery is not holding a charge", it's not designed to. But, how it releases the charhe, is another story. Obviously, it's also dependant on use. Remember, the phone is only rated at 5 hours talk time. I can't think of a time I've actually tried that, but when I have been caught on the phone for extended periods I've only gotten at most 2 hours of conversation out of a full battery.

my battery doesnt last too bad in my evo. granted not like the old days, but i do get about 12-15 hours on a 1700 mah battery and a powerskin charging case with a built in 1500 mah battery. This is in a poor service area.. constantly switching into and out of roaming. i keep 4g, wifi, mobile network all off and screen brightness at about 25%.. this is with moderate txt, some light game play, occasional turn on 3g to check email and browse web. im expecting better now thzt i am rooted with energy rom and anthrax kernel.
