So I've been dealing w/ this little issue for the past few months where I can tell that the battery meter isn't reading correctly when the battery starts getting super laggy, slow to respond to inputs, etc. I've also experienced the same issues that I've read about here on the forums where after resetting the phone, I get drastic changes in before and after readings.
Just today I decided to search for the process to properly recalibrate the battery stats...jesus christ, there are opinions everywhere! Out of all the ones I've read, I've never understood the repeated charging and depleting cycle, THEN resetting the battery stats. Isn't the purpose of the battery stats to teach it to learn how to use the battery, so why wouldn't we be resetting the stats from either a completely dead or completely charged battery, then doing the power or draining cycles a few times?
Either way, I completely killed the battery lastnight, reset the stats and charged it w/ the phone on but in airplane mode. Unplugged for a moment, plugged it back in, LED went from red to blue within a few minutes. Did it one more time since I read random suggestions about "boosting" the battery like this. I then powered the phone off and did the same thing. During use today, the meter has been steadily dropping, maybe even a little faster than I'd expected, but I chalked it up to the phone learning.
Now the issue I'm having it that the phone froze about three times after doing the resetting and charging. Now mind you, this has happened before immediately after I flashed Syndicate w/o even touching the battery stats before or after a fresh ROM/Kernal installation, so I'm not goint to immediately assume it's because I may have done the battery stats steps incorrectly. At this point, I just want a truely accurate reading...none of the sluggishness when it says 29% then resetting takes it to 9% and the screen goes dim, the freezing the phone gets when it goes below 15%, etc.
There must be one, solid, concrete way to do this battery meter thing that doesn't involve everyone getting into a pissing contest about who is right, who is wrong, getting into a long speech about lithium battery blah blah blah. I just want a meter that reads accurately, period.
I agree. I have heard several methods to calibrate a battery but not one concrete method. I have read that its bad to run a Lithium ION battery all of the way down. Then I read that its the best way to condition the battery. Anyone with the proper method to calibrate the battery and make the reading the most accurate will get some "thanks" from me.

While I can't say the meter was dead accurate when stock, at least it doesn't give me the issues I've been experiencing. There must be a way to find out how Sammy does it.
I find that the charge to 100 on, unplug, charge to 100 off, unplug, charge to 100 on, then turn of and clear battery stats from cwm works. I have no logical explanation why but i notice a significant battery boost and fture efficiency. Only reason it gets screwed up is flashing something new, but when I redo the process I get the same battery efficiency back. Also make sure any flashes don't activate syncing. I flashed something that turned mail syncing on and it was killing my battery.
My opinion on the whole battery deal is do nothing. These are lithium ion batteries, they have no "memory" effect. About the only way you can hurt them is to deep discharge them repeatedly or overcharge repeatedly. I don't feel there is a need to fully cycle 100%-0%-100%. Or charge off, then on, then unplug, blah blah blah... That probably just overcharges the battery anyway.
A while back I tried monkeying around with all those tips and tricks people post, didn't seem to do anything for my life. After a week or so of normal use the phone seems to learn your battery anyway. I say just let the phone do its thing, spend your time playing with cool apps or something.
No offense Insanity, but did you even read my post or know what batter stats does? I know Li batteries don't have a memory, its been stated before in nasseum. Battery stats is an application that tells or phones how to properly read the charge/discharge rate of the battery. Please don't take this thread down the "memory" blah blah blah road, because that's not the issue here. My battery is perfectly fine, I'm trying to find out an unbiased, educated, personal-opinionless and concrete way that battery stats need to be programmed, ie the way Sammy does it since I didn't have this problem until I started flashing roms.
All I'm saying is don't do anything, the phone will learn. When I stopped clearing battery stats every time I thought there was a problem I stopped having drastic drops in my battery meter after rebooting like some people have run into.
I haven't cleared battery stats in months now, my battery life is great and my phone doesn't lose mass amounts of battery randomly on reboot.
I also stated in my OP that I've been on this rom for a few months, if not even longer since I've been bouncing back and forth between Syndicate and Bonzai. Point is, months later I'm still having the issue, so clearly something isn't calibrating correctly, hence my creation of this thread.
Even if the battery stats are wrong/improperly calibrated/whatever you would call it I don't see how that would lead to lockups. Are you getting FCs at all? Maybe there's some data corruption at play? Is your filesystem journaled? When the phone locks up are you able to logcat?
The lockups I'm referring to only happen after I reset the battery stats, then it stops after a day or so or charging and discharging...it just never reads the battery correctly even after repeated usage. No FC's, phone just locks and a battery pull is the only way to stop it, journaling is on because the risk of FC's isn't work the slight speed increase and I honestly have no clue about how to check and/or post logcats.

Make sure debug mode is enabled on your phone before it locks. When it locks plug your phone into your PC. Try from a DOS prompt inside a directory with the adb executable:
adb logcat > filename.txt
Let it run for a minute or so then ctrl-c to break out of it. If the phone is in fact completely locked it won't work, but its worth a shot to try to get a behind the scenes look at what's going on when your phone pukes. If you notice it lagging or something that makes you think its about to puke, try to get a logcat of that too. Use different file names when you logcat so you don't overwrite the old one.
issues with battery meter
Ive had the same exact problem. Its been fine since september when i got the phoen and even through flashing the phone. Everynow and again it will have a large drop after flashing but i typically have written that off as the power it takes to flash. Now after ec05 and this gingerbread leak, may battery stats is unreliable. It will stay at a certain percent until my battery dies. At any given moment i never know how much battery is left.

So.... following Mikey1022's thread crusade, I'm almost hesitant to post this here, but I feel like I'm going to get the most accurate answer from the people in this forum vs general...
On Cyanogens site, I found this for Battery Recalibration:
Battery recalibration
If you're experiencing higher than normal battery drain, try the following:
1. Charge the phone to full battery; let it keep charging until the battery says it is fully charged. Do not wait until the light is green, it isn't always fully charged, causing a lot of inaccuracies. (You can check by going to: Settings -> About Phone -> Status -> Battery Level = Full.)
2. Boot to recovery mode and go to console (or adb shell) and type:
mount -a
rm /data/system/batterystats.bin
NOTE: Newer Amon_Ra recoveries have an option to delete the battery stats, do this in place of the console commands above.
NOTE: To have the most accurate of battery stats, reboot the phone immediately after wiping the battery stats and wait for CM to boot completely to the desktop. Once your entire boot is done and you have full access to the phone, go ahead and pull the charger and continue with this troubleshooter.
1. Do not charge the phone until after draining the battery completely, resulting in it automatically shutting off.
2. Recharge the phone completely and then use as you normally would.
SO I'm at work, and don't have the option to check this, but unlike "hardware" battery calibration I'm mostly curious about removing the batterystats.bin
Would it help us with our battery woes, or do ours go deeper? For some reason, I noticed that mine's been draining a LOT faster in the past month or so then before...
Any thought?
This belongs in the general area?
I really don't think there's a magic forumula for these LIPO batteries. Unless you have a bad battery, you like numerous others need to join the battery 12 step program. I've already been through it. "Hello, my name is Sean and I'm obsessed with my battery life."
Long story short, just keep charge the battery when it gets low. If you work near an outlet or computer, and sleep near one - it's quite easy to keep the battery up throughout the day.
FYI, I've read up on this a bit regarding laptop batteries. It has nothing to do with the actual battery life or the "memory effect" (these batteries don't have a memory effect). It has to do with the OS's interpretation of the battery's performance and how it is reported to the user. So you're really recalibrating Android, not the physical battery. As far as I've read, this only "needs" to be done once in a great while, once a year maybe. Or if you notice something really odd with the battery level reporting.
I did this this morning as well since my phone was fully charged and ready to try it. Not had any hugely bad side effects from the phone and new battery (1750), but we will see if this changes anything.

Well, actually, that's why I put it in the development forum. These instructions are telling us to remove things from the system. Also on that note, my battery went from being at 30% full by 10pm (fully charged in the morning) to 30% full by 3pm (YES, 3) so something is definitely wrong, not just "I am obsessed with my battery life". Mind you, I'm at work until 2, so my phone drains to 30% on IDLE, with screen off. I was thinking maybe Android is misinterpreting something? I removed all programs that I thought might be causing this, turned off wifi, bt, gps, still no go. Maybe bad battery?
What I'm thinking this may help with is the fully charged issue the incredible has. I wouldn't follow the above instructions exactly however. Let me explain.
If you've ever noticed, the OS doesn't report "fully charged" correctly. Charge your battery to full (where both the green light comes on AND the "about phone" battery status says "Full". Now shut your phone off, you'll notice your light turns orange again, and will charge for about 30 minutes, sometimes more depending on how far off the battery is. If you turn on your phone after this, you'll notice you stay at 100% for quite some time. This is the case with a lot of incredibles from what I've seen... It probably has to do with the calibration notated above.
I would say do the calibration noted above, however, charge it the way I just noted (charge to full, shut the phone off, let it finish charging to full...). Then follow the rest of the steps immediately following. Might make a difference.
EDIT: this is probably even more true for the 1750mAh battery.
calibration and such has been discussed but not under its own name on page 3 i explain abit about the lithim ion battery vs nickel cadium.

I was witness to that thread, and yes, you are correct, Lithium Ion batteries do not need to be conditioned, it is useless... However, we are not talking of conditioning, we are talking of proper reporting of battery life through the OS, which IS how Lithium Ion memory works. This is not saying to Cycle your battery 3 times to "condition" it to full potential. It is stating that the OS is not properly calibrated to report the proper life of the battery. If the OS cuts the charging of a Lithium Ion battery because it "thinks" it is at 100% charge, while the battery itself is at 80% (just a random example), then your battery life is going to appear to be shorter than it should. The example posted above would theoretically reset the OS so that when it says the battery is at 100%, it indeed is at 100%, preventing it from cutting a charge before it should. See my post previous post if you are confused. "Conditioning" is an entirely different animal, in which you "train" the batteries memory (in Nickel cad batteries) before utilizing your battery in normal charging operations. Lithium Ion does not have this memory, making "Conditioning" useless.
Moral to the Story here is to fully charge your phone when its off and you don't have to deal with any of these work arounds. Am I right?
buy a second battery and an external charger. I do this with every phone and I always seam to get battery life that is on the high side of what people report
Thank you for correcting that was bit early in the morning thought it was same question.

What, exactly, are you trying that's giving the improvement? The OP's suggestion of booting into recovery and deleting battery stats, or the other common suggestion of turning phone off for the remainder of the charge? 70% after over 8 hours is FAR better than I'm seeing, and I'd like to see the same results.

Just tried this method, fully charging the phone when it's off then wiping the battery stats. Hoping it'll fix the annoying problem that the battery doesn't fully charge when the phone is on, although I'm not sure if it even can be fixed -- does anyone know?
I'll update if I remember next time I charge it.
Giving a try
Hey guys. I am also giving this a try today.
I just completely charged my battery last night with it off. This morning I unplugged the charger (while the phone was still off) and plugged back in to make sure that the battery was fully charged. The green light turned orange for a couple of minutes and back to green so I proceeded to boot to recovery and removed the battery file. I am also running a Seidio 1750mah.
I am now up and running. I will post later this afternoon to let you know how it's going.
If this fixes the weird battery bug where the Incredible doesn't charge fully, I will kiss the OP. Seriously.
Hi all,
I am puzzled by my problem. I am using Virtuous 2.7 + King's BFS kernel #4.
My phone battery will drop quickly from 100% to 92% right after unplugged from the power cord. By quickly, I meant I did not use the phone, killed all tasks, and battery will drop to 92% literally in minutes.
Bump charging, wiping battery stats, wiping dalvik cache, killing all tasks are not helping at all. I don't have SetCPU, but someone in the forum mentioned they have SetCPU, and it is not helping either.
Is anyone having this problem? Does anyone have any idea on how to solve this?
Please help.
Thank you!!!

I spoke to RMK as well as others about this in IRC, doesn't look like anything we can do, deep in the HTC code I guess.
I have the same issue using SkyRaider 3.1. Battery is 100% then after 5-10 minutes drops down to low 90s. It bothered me at first but after several days of moderate to heavy use and still having almost 50% battery left at the end of the day, I just figured it was some kind of bug when reading the battery level at the beginning. How is your battery life overall? If it's like mine, then i wouldn't worry too much about it as long as it's lasting longer. I'm using the 1750mAh battery from Sedio.
I was having the exact same problems until I went back to stock everything and bump charged. Took the OTA for 2.2, rooted, custom recovery, bump charged, wiped stats and cache and now I'm good to go. I usually dont think crap like this works but it made a huge difference in battery life and stopped the 100-90% problems I was having.

Is this a once time fix thing or do you have to do it every time you charge?
bump charging 4 or 5 times in a row (basically bump as many times as you need to to get it to where the light turns green withing a minute of 2 or plugging it in again) and then wiping battery stats solved this for me... kinda.. i still have to bump twice, but after that it'll stay at 100 for a good while and work it's way down normally, no jumping 10% down..

That is bump charging. Something htc is unable or unwilling to fix.
The issue has been known for a while and you have to 'bump charge' every time to avoid the 5-10% drop.
Here's their response about fixing the "bump charge".

Do you bump charge every single time you charge right now? It's pain in the butt if I have to bump charge everyday.
Yup every day. 4 or 5 times is way overkill though. Just charge phone until green, turn off (don't need to unplug), wait until it turns green then do the plug/unplug one more time.

Went to stock (official OTA), rooted, custom recovery, bump charged, reset stats and cache and I'm good now.
I charged it to "full" while it was powered on. Once the light turned green I turned the phone off, charged again until the light turned green. Took about 25 minutes. Powered up in recovery wiped battery and cache and now I'm good. The key is after doing all this you have to let the phone completely die.
If you're wiping your battery stats after a bump charge, you will have this problem every time you don't bump charge.
If you wipe your battery stats after it goes green without a bump charge, you won't have this problem.
This is because the software thinks the bump charged battery levels equal 100% charge. A bump charge adds approximately 10 percent of charge.
Formatting your phone or any software changes won't actually do anything other than wipe your battery stats while your phone is not at bump charge levels.

The reason this happens is because the battery gets charged fully to 100%, and then is allowed to slowly drain back to 90% (or so) before it's charged back to 100% again. This is how Lithium batteries are charged.
Try this: charge the battery to 100%, and immediately disconnect it after it's full. Notice how the battery doesn't drop to the low 90's immediately.
The reason "bump charging" appears to work is because there is no drain on the battery, since the phone is off. It goes to 100% and stops.
There's nothing we can do code-wise to fix this; it's just how the battery technology works. Keeping it fully charged at 100% while on would damage the charging capacity of our phones.
Btw.. wrong forum.
Solutions in search of a problem
Let me preface this by saying that I’m not an electrical engineer, or any sort of expert on phone hardware, but I think a couple issues are being confused. I’ve seen many posts about this battery “problem” here and elsewhere and an important point is being missed. People are confusing what the battery is actually doing with what the phone SAYS the battery is doing. They are NOT the same thing. The battery is a physical device and it will do what it’s going to do.
Battery life is a function of battery quality, initial state of charge, and demand. If you want the battery to last longer, look at ways of reducing demand. What applications are in use? How long is the screen on? What brightness level? Overclocking and undervolting settings? All these will affect ACTUAL battery life.
At lot of the “solutions” discussed have nothing to do with conserving energy use, but have everything to do with messing with how the phone REPORTS the state of charge. A good example is the issue of the initial drop reported by many users during the first few minutes after unplugging the charger. I see this on my own phone. If the phone is “taught” that 100% charge is when it is totally crammed with juice and plugged in as well, it’s not surprising that there is a good bit of voltage drop (+/- 10%?) right after unplugging. Does this mean there is a problem? NO! It’s just the battery doing what batteries do. A lot of the suggestions about wiping battery stats and such have nothing to do with saving energy. They are ways of fiddling with how the phone REPORTS its condition under various circumstances.
My advice: if you are happy with how your battery lasts, over the course of a day or so, then learn to relax, crack open a cold brew, and revel in just what a great phone the Incredible is. If your battery isn’t lasting as long as you need it to, then look at ways to save power or get a larger capacity battery. Tweaking the battery meter function is simply a feel-good exercise and won’t get you any actual improved performance. END OF RANT.
I can confirm that my gf's phone and my good buddies phone(both were never rooted) have never had a problem with the phone charging up slow first off(both phones charge about 1% per minute). And since they accepted the OTA, have not had the problem of charging to 100% and quickly jumping down to 90%. For instance, the other day my buddy charged his phone while on to 100%, played a game for about 2 minutes and closed it, battery was at 99%. Now I have tried and continually try every possible solution to my battery dying quick and charging slow, but am realizing that this must just be the cost of customizing my phone to my liking. And at least for the moment, a stock 2.2 DINC is just not an option for me.

Sorry that I posted in the wrong forum. I thought this is related to the kernel or ROM I am using (Which is development right????).
Not to question your knowledge about the "battery technology", but why is it only happening to certain people? Nowadays most device are using Li-ion battery, why this phenomenon do not occur to all devices?
Normally I charge my phone nightly right before I go to bed and don't plug it in at all during the day usually.
I have noticed that on days where I have to use my phone heavily and require a charge midway through the day for the next week my phones battery life is almost cut in half. If I charge it regularly at night for a week or so the battery life will go back to normal. Has anyone else noticed this behavior? I'm trying to figure out if this is an incredible issue or an android issue.
Another thing I noticed is that under the battery stats it lists that my awake time is 43 hours. Its just slightly less that the up time. This makes me think that my phone isn't going to sleep. Anyone know how to tell if my phone is sleeping or tell me which app is keeping my phone from sleeping?
Install this app
http://www.appbrain.com/app/spare-parts/com.androidapps.spare_parts
Go to partial wake. in one of the drop downs.
I checked the partial wake usage and I don't see anything out of the ordinary.
I actually have an update to the situation. As a last resort I wiped my phone and loaded Cyanogen 6.1. At first it was working awesome. Battery life was awesome but as time went on the battery life got worse and worse and now i'm back where I started.
It sure seems like there is software problem with the way the phone tracks the battery usage/charging information. As I said it seems like charging the phone midway through the day or charging the phone before the phone is dead seems to have a negative effect on the battery. I don't get it. Letting the phone completely die isn't realistic. Charging the phone when I go to bed without affecting how long the phone last after the next charge should be totally doable you would think.
Does anyone have any suggestions or insight that might help me out.
You don't say if you charge with the phone powered off or on. But sound like you're always charging with the phone turned on.
I don't think the phone charges fully while turned on (to prevent overheating maybe? ).
If you can, I'd suggest trying to charge with the phone off, at least during the nightly charge.

Yes I do charge my phone while its powered on (like the rest of the world). I don't know anyone that turns their phone off to charge.
My phone is paid for by my company so that they can get ahold of me in the event of a server failure or some other IT related disaster. If the phone was off I wouldn't be able to receive those important calls.
I can't believe no one else has witnessed this type of activity with the incredible. I have tried 2 phones (replaced for an unrelated reason) and 3 batteries. The behavior seems like a software glitch. I have noticed with with both AOSP and Sense Roms.
Does anyone have an in depth understanding of how the battery system works on this phone. I also have an Iphone and the battery life compared to my android phone is ridiculous. I would use the Iphone exclusively but it doesn't do everything my android phone can do. I'm hoping there is a way to fix this.
Well, now you do know someone who charges with their phone off. Me!
I'm in IT as well and on call one week per month. But we don't run a third shift, so late night calls are almost never, and they have my land line number.
Back on topic, I have experienced better battery life while charging with the phone off. Maybe you can get an external charger until a solution is found.

Well i'm on call 24/7 and I don't have a landline.
What do you mean by "get an external charger until a solution is found." Do you mean a second charger to charge during the day? I have plenty of chargers. Thats part of the problem. Charging in the middle of the day I believe is causing the problem. Until a solution is found? Are you saying there is in fact a problem?
Having to leave my phone plugged in all day kind of defeats the purpose of having a wireless phone don't you think?
Please...anyone have any knowledge of how the charging system works in android and specifically how it might work differently on the incredible?

I should have said get an extra battery and a stand-alone charger that allows you to charge the extra battery while it's disconnected from the phone.
Have you read the thread in general titled 'your battery gauge is lying to you'. (or something like that). Good read. Also there's hundreds of other threads on the inc's battery issues. Well known problem.

If your up time and awake time are essentially the same, you definitely have something running in the background. Try menu/settings/applications/running services and see what program might be running that shouldn't be. You can also use an app called System Panel to do a comprehensive survey. I recently had an update that resulted in the program running continuously in the background, affecting my battery life.
Some other threads have discussed that after 40+ hours of up time, their phone goes into max CPU usage all the time. Again, using the app System Panel, I confirmed this for my own phone at 45 hours. My ROM is the stock Froyo 2.2 with a custom kernel. the simple solution is to power off/power on the phone which resets the uptime.
My routine is to charge the phone with power on over night so I can use the alarm. When I get up in the morning, I power off the phone and bump charge it for about 30 minutes until the light turns green again. Then I'm usually good for about 10 - 12 hours of uptime with 3-4 hours of awake time using a 1500 battery. That time can also be reduced considerably if I'm receiving a poor 3G signal.
I did originally have a problem with a program not allowing my phone to sleep but I have since uninstalled that program and now my wake time numbers are where they should be. I think the remaining battery issues are a result of me having to charge my phone in the middle of the day as a result of the misbehaving program prior to me uninstalling it.
It almost seems like the the battery in the incredible has a memory. On a hunch I have started completely discharging my phone completely everynight before I put it on the charger. As a result my battery life as almost doubled. When I get home at night I start playing angry birds with the brightness at full until the battery gets to about 3 percent left. This obviously isn't a permanent solution but It certainly sheds some light on the root of the problem.
Prior to doing the full discharge I did a bump charge and wiped my battery stats. The battery is working great now. I wish someone would create a kernal/rom that has this issue resolved. Since these new lithium batteries aren't supposed to have a memory anymore I'm thinking it has to be something that the OS is doing with the battery stats file.
According to this article you should fully charge and discharge once every 30 or so charging cycles to resync the battery meter with the actual battery voltage. So maybe the complete discharge fixed your problems.

not sure if this will help or not, but i have been running advanced task killer ever since 2.1(haven't gotten around to uninstalling before now, ha ha) and recently uninstalled it and installed watchdog task manager and my battery has increased two fold!
just my two cents worth.
What does it mean if, after resetting your phone, the battery level drops from 60% to 13%? Is that hardware? Is that the ROM? is that the battery?
I ask because, after hanging on a PRL update (that i don't think was successful) for an hour, the phone wouldn't stop pulling down data for any discernible reason, so I reset it. Before the reset, the SRF 1.2 baterry icon showed 60% battery and after booting back up, the phone prompted me to charge it because it was down to 13%. In addition, I put the phone on the charger for the PRL update, during which the charge level actually decreased slightly and the phone heat up to around 35C. Spare Parts reports the battery is healthy. Is this just a freak occurance or should I be worried?
Don't worry. Just run the battery calabation procedures. Theres several ways to do it floating around the threads. Also, i've had prl updates hang as well just check under phone status in settings if it changed. Even when it has hung on me it properly updated and showed whatever I was changing to.

this happens to me a lot...i have calibrated a few times and it always happens...it usually happens after i dip below 70 percent in battery life..when i reboot, it can say 8 % or worse.and sometimes gets stuck at at a specific battery for a while and reboot sometimes brings it back to the normal battery level..i mentioned this before in a thread but I haven't found a solution...so i barely reboot my phone unless i need to backup in clockwork or flash something
Oh man. I reboot my phone once a day to flush the RAM and keep the system fresh.
I rebooted in CWM to reset the battery stats, btw, and when I hit the "reboot phone" command, it rebooted into CWM 3.0.2.5 (I'm running the latest 3.1.0.1), which was jarring. Before that, after leaving it on charger for less than an hour, it jumped back up to about 57% and charged to full in another hour or so. Unfortunately, the batt. reported a full charge at 93%. I bump charged it up to 94%, but I ultimately decided to reset the stats just the same.
Are these known symptoms of something, or just hiccups?
I have had this issue as well. I believe it to be a calibration issue. I swap three different batteries so I attribute it to the different ones.
Strange thing happened the other day, my phone was at 22% or so and then all of a sudden just shut off. I switched batteries and it was fine, but strange.
I'm beginning to wonder if my battery is borked for my phone. I've done every single thing out there to ensure my battery was always 100% charged and calibrated.
However, today my phone read as being 100%. Went home, charged it up when the phone was powered off to make sure it actually did get to 100%. It did that, all was fine, or so I thought. A bit later, I check my phone and it's reading 72%.
There is no way this is normal for a battery. My phone has been dropped a couple times (mild drops, not huge ones), so wondering if it's possible a cell in the battery has been borked?
Had it been calibrated?

I said it in my first post.
What ROM? Did you look at it when you removed the charger? Did it still say 100%? Was it warm when you picked it up? Did you have signal? Did you install any new apps? Did you just reboot? Did you have a random reboot?
Don't sweat it, charge it and check it again.
No ROM, just a regular Gingerbread shoved through Odin, along with CWM purple.
The phone was 100% before I put it on the charger. I only checked the phone when I heard it doing the signal lost/found noise, and that's when I saw it went down dramatically (there is NO way that attempting to find a signal can lose battery power by 28% in 30 minutes).
Phone was not warm at all.
I have about 2 bars of signal.
I have not installed any new apps.
I did not reboot.
I never have random reboots (it's a reason why I don't mess with the Gingerbread ROMs).
I'm not sweating this, I'm more annoyed. And, all people do is say "Charge it, do this and that to calibrate, turn off phone, charge it again, reset battery stats, spin it 360 degrees, read it a bed time story...." But it simply doesn't fix it some times.
Wouldn't this point towards a faulty cell in the battery?

Look at your percentage when you pull it off charge. There is a bug in the Gingerbread leaks that kills the bump charging. So while it says 100% while connected, at that time it continues to run at 100 Mhz but not charging actually killing your battery. So you can go back to EC05 stock and see if it still does it to be sure. Assuming you did reset the battery stats already with that bed time story...LOL.
I see Spare Parts has a "battery condition" category. Can anyone verify its accuracy?
