There has been much confusion and frustration surrounding our battery life and these custom roms. Some of us have great battery while others are having horrid problems.
I am writing this guide in the hopes it will help all of you with problems getting that great battery life.
This is a guide written from my own experience and technical understanding.
First, Your phone should drain, on average, 1% per hour or less while in standby mode (screen off). If you are not getting this average, you need to calibrate your battery.
ALWAYS flash a new rom with your phone at 100% battery - no exceptions!
i know some guides say to run battery down to 2% and then charge, but i never had much luck with this.
1) Before you flash your rom, charge your battery to 100% with the phone ON.
2) Once it says fully charged, turn the phone off and plug it in and wait for the on screen display to say 100% (this will take 5 to 10 min)
3) Turn the phone back on, and plug it in and charge till it says 100%
4) turn off the phone and charge again while off until the on screen battery indicator says 100% (again this will take 5 to 10 min)
5) repeat steps 1 thru 4 as many times as you feel comfortable, I recommend at least twice (I do it 3 times)
6) when you are satisfied with the charge, and the phone is still OFF with the indicator saying 100%, unplug the phone, remove the battery, and place the phone in download mode (hold vol down and plug into the PC)
7) flash your package (this is done in odin with the battery removed)
8) The first boot after the flash needs to be into Clockwork Recovery, wipe battery stats at this time (most roms will boot into recovery automatically, if not, boot into recovery manually)
9) after you have wiped your battery stats, wipe cache and other data (if the rom you are flashing requires this, if not, skip this step)
10) Boot the rom to the homescreen.
11) from this point on, you will use your phone like normal until the phone completely shuts off. this SHOULD take a while. you should see improved battery life during this stage. If not, dont panic, just run the battery down until the phone shuts off
12) once the phone shuts off (try to time this to happen at bedtime) plug the phone in and allow it to charge in the OFF position
13) once it is at 100% again, use the phone like normal and enjoy your new battery life.
IF YOU ARE DOING THIS WHILE NOT FLASHING A NEW ROM
Do steps 1-4 as many times as needed, I recommend at least twice, i do this 3 times
on the last charge up (your phone should be off while charging during this step) unplug the phone and boot directly into recovery and wipe battery stats. then proceed with the rest of the guide.
TO TEST THIS
charge to phone to 100%, try not to mess with it for an hour or so.. (light usage at most) you should still be at 100% or 99% after an hour. If you are at 95% or below, then the calibration has failed. (unless you have been using the phone or are in a very low to no signal area).
this calibration method is crucial to good battery life. Before I started doing this i was getting very bad battery life. Click on my username and look at my previous posts.. you will read about me *****ing badly about my battery, this is what I did and it has worked amazingly well.
I hope this helps
I combined a lot of techniques ive seen in other threads and some websites and then created this technique which seems to work really well.
I have used this technique and can confirm, it works well if done properly.

Are the first few steps what is referred to as "bump charging"?
I think this has worked quite well. I flashed Humble 1.2 (at 40% battery) last night, charged up, then started this procedure. After I got done, I took it off the charger and after 15 minutes of trying a new game, listening to a minute of music, and checking various things, I was still at 100%. i left it off, went to bed with wi-fi on, and woke up at 95%. Awesome. My all-day phone is back.

What happens after the calibration process? do i have to do this everytime i charge my battery or does like normal mean i can just leave it charge whenever. Also with what frequency should i be doing this? once a month calibration?
Just did this... 1 hour 15 mins. and still at 100% Sent two text messages out and played Words with Friends for a minute. Thanks!
Did this and it didn't work advice on what I am doing wrong I did the bump charge 2 times ran the phone down 100% and am now looking at 88 percent of next to no use after about an hour and a half of having the phone on.

I am in the same boat with you.....I'll just have to accept the fact that I will have to charge every 6 hours, which was a 2 hour step up from the TB.
This works, going on 17 hours and still at 65%.

What I am curious to know is what is usage like for the people that this worked for. Don't get me wrong I'm not doubting the op but I am a pretty heavy user and even so I'm not really experiencing this awesome battery life everyone talks about when I'm not using it heavily

For all of you that are getting the great life, what percentage does it list for display? This is under settings > about phone > battery use.
I'll have to try this method. My battery life is actually worse now after I tried doing the drain to 2% method. I'll report back with my observations.
Are we talking 3G or 4G here?
I would find it useful when people are talking about how good (or bad) their battery life is to know if they are in a 4G area and have 4G turned on, or are they using 3G only?
Trying to figure out how bad a hit 4G takes on my phone...
Thanks.

So I tried this out yesterday...I don't have a rooted phone so I could not wipe battery stats (does anyone know how to do this without rooting your phone?)...but I did follow steps 1-4 three times and I have gone 23 hours on my charge without having to plug it in. I am in a 4g area and had 4g and background services on for the full 23 hours. Had bluetooth, GPS, and wifi turned off. I sent a couple texts, used whatsapp to send texts, used google voice to send texts, made 3 phone calls (about 4 to 5 min each) played angry birds for about 20 min, played words with friends for 10 min, surfed the web on and off, was on tapatalk and browsing forums for about 20 min and I installed a new keyboard and web browser on my phone in those 23 hours.
I am very curious to know if this will improve battery life after that first initial bump charge.
If you do a regular charge after depleting the charge, do you still see improved battery life?

Yes. The phone will pull the necessary power for download mode and the Odin flash from the USB port. Just be sure to use a primary USB port (usually the ones on the back of the computer), rather than a hub, as the hub tends to cause problems.

To help with Battery Life you can do these steps exactly:
1) Turn your device ON and Charge the device for 8 hours or more
2) Unplug the device and Turn the phone OFF and charge for 1 hour
3) Unplug the device Turn ON wait 2 minutes and Turn OFF and charge for another hour Your battery life should almost double, I tested this on my pops evo and my epic...MAJOR DIFFERENCE
After installing a new Kernel it is recommended tat you recalibrate our battery to get the most life out of your battery. I suggest using Phoenix kernel but your a grown man[or woman] choose your kernel
Hope this helps
Thx to bigdbag for these additional steps
Post #21
My god. I was highly skeptical of this but I tried a quick version of the instructions.
I did the following:
1. Charge to 100% while phone = ON
2. Once at 100%, unplug charger and turn phone OFF
3. Plug in charger for 5 minutes while phone = OFF
4. Unplug charger and turn phone ON
5. Leave phone ON for 5 minutes
6. Plug in charger for 5 minutes while phone = OFF
and the results... are miraculous. I'm running Phoenix Kernel v.1.43 and stock rom w/ drm removed.

Trick trick trick trickle charge Battery is in fast charge mode when it begins charging from a certain percentage (although slow). When the charge is in the 90's and you unplug and plug it back in it trickle charges to completion. This does indeed work. Works best in my opinion when you do this after you let the battery completely drain, plug in, recovery mode, wipe battery stats and then turn on.
And then do what you stated above.
Yes!!!!!!!!
Totally gonna do this since my battery seems to be on the down side compared to everyone else's. :]

i also reccomend an external battery charger that u place the battery into. no need for the trick. Ive used this trick before i got the external charger and yes it does work very well!
+1 on the ext charger. I have two batt. If I charge with the phone... one- goes from 100 to 97 withing sec from when I unplug it and two- it doesn't last as long. Using the charge and switching out the batts. Stays at 100 for a while and it will last forever too.

I noticed this as well, so when my indicator LED turns blue and it says 100%, I unplug, then immediately plug back in until blue.. lather rinse repeat.. after about 3 or 4 times it finally stays at 100% when unplugged..
That being said, I'm gonna have to try to find an external charger and another battery...
My local sprint store sells a charger with extra battery for $49.99. Its an external charger that fits in your pocket. With charging cord of course.

tried this, doesnt' seem to work for me. I unplugged, turned phone off, and charged, but phone said fully charged after like 15 minutes, I assume once it says 100% on the green battery that shows up when phone is off that I shouldn't just let it sit there? its not charging at that point anymore is it?
then i unplugged, turned on phone, waited 2 minutes, turned off, charged again, 15 minutes or so it was fully charged again.
This reminds me of the chargobics that some ppl did on their evo to get better battery life....never really helped me.

So what you're suggesting (re: recovery/battery stats) is the following:
1. use the phone until the battery completely dies.
2. plug the phone in
3. boot into recovery (clockwork ?)
4. wipe battery stats
5. turn the phone on
6. do the 'plug me in' dance after it's fully charged
What if the battery is fully charged and you wipe the battery stats ?
idk i think i used to do something similar on my Hero and even back on my (WinMo) Mogul and Touch Pro and never really got much out of it......
However, today I did this and I swear I'm getting great battery life today. Have never gotten past 12 hours and I'm currently sitting at about 40% left at 12 hours. Could be the placebo effect but we'll see..... even played some angry birds today.

FTW!!!
Took 11 days to get here, but worth EVERY penny. I never need to worry about to battery life anymore. Hell, now that I charge my batteries using the external charger, I get atleast 8-10 hours with constant use, and my battery doesn't drop from 100 right away. I never get to the 3rd battery by the end of the day and thats with a 18 hour day unplugged. Worth it.
I have noticed some weirdness with the battery. I looked at the juiceplotter graph after the battery had been left charging all night, and it would charge to 100 and then over th course of half an hour drop down to 95% or so and then recharge up to 100 over and over and over again. I have taken it off the charger sometimes and the battery has gone from 100% to 96 % within a couple minutes and other times it stays at 100% for over an hour. It was a matter of luck as to when I pulled my phone off I guess, when it was really at 100% or really at 95-97% or anywhere inbetween.
Gonna try this PITA method of charging. Hope it works, but damn is it inconvenient.
The external battery charger is the way to go. i have also noticed when i rarely charge from the phone that it sometimes wont stay at 100 but for a minute then drop to 97. i get 55 hours to one battery with moderate usage.
This didnt really do anything. Unplugged from my charger at 1:50pm, its been exactly 2 hours and its at 77%. Mostly my phone was in my pocket, and I did very light browsing over 3g (maybe 10 minutes).
I'm on Latest Epic Experience with Mixup Kernel. And I don't have OC widget or Setcpu.

Is it really that much better? If so, what causes it to be better on battery life? I am getting great battery life using the mixup kernel because I have juicedefender and setcpu working hard to conserve battery life. Would Phoenix make a difference?
Just a FYI, Lithium-Ion batteries don't hold a memory like NiCad batteries did. It is also NOT good to drain them all the way down.

Do I have to wipe anything?
There have been about eleventeen thousand questions across multiple threads on how to calibrate the battery properly...figured it probably should be a sticky in here if possible.
You have to know how to get into Recovery mode. You can do this with Quickboot when the phone is on, or the powered off phone method:
1. Power off phone or pull battery and replace.
2. Hold all three of these buttons down: Vol-Down, Camera button (lower left as you look at the phone) and Power on button).
3. You will see a small graphical menu come up. Most of us are using Clockwork, so I will focus on that - it will be a green menu.
For the battery wipe, Go to Advanced, navigate the menu with the vol up/down keys, and select using the camera button.
There are three ways so far:
The Drain Way:
1. Drain it down until fully dead.
2. Charge normally to full.
3. Reboot to Clockwork recovery and wipe battery stats (under advanced, on second page), reboot phone.
4. Turn everything on, flashlight, Bluetooth, Wi-Fi, Pandora, the whole nine, to quickly drain it completely dead.
5. Charge normally to full.
The Powered Off Charge way:
1. Charge your phone 100% while it’s on
2. Unplug it from the charger, power off, then charge it up to 100% with it in a powered off state.
3. Unplug charger from phone. Power it on, and then charge it to 100% while the phone is on.
4. Unplug the charger and then reboot into Clockwork, go to advanced and clear the battery stats.
5. Power on, charge to full, and then enjoy.
Third option (thanks squshy 7), I paraphrased it and wrote it out a bit for ease.
Maybe we can call it the Mr. Miagi Charge way....aka Power On, Power Off, Charge On, Charge Off way lol
(the parentheses are the state of the phone)
1. Start with the phone powered on.
2. (Phone on) Charge battery until the LED turns blue
3. (Phone on) Unplug the phone from the charger, wait until the LED turns off
4. Power off the phone.
5. (Phone off) Plug the adapter into the phone, charge it up until the LED turns blue
6. (Phone off) Unplug, wait until the LED turns off
7. Power the phone on.
8. Wait until the phone is booted back up all the way, and then power it off again
9. (Phone off) Plug the adapter into the phone, charge it up until the LED turns blue.
10. Boot the phone into recovery mode
11. Go to Advanced, and then choose Wipe Battery Stats.
12. Power the phone on and use normally.
Still a noob, but what would exactly need you to have to Calibrate Battery? Also what exactly does it do for the user?
P.S I'm sure I could look this up but it would be nice to see it in your thread for others to see

Well it's really a matter of semantics...you're not calibrating the battery, per say...it's actually calibrating how android is reading the battery. (these phones use Li-ion batteries, which don't use memory, so they themselves never actually need "calibrated" like some older types of rechargeables)
But...as far as what this means to you, its kind of a big deal! It improves battery life in letting android know when your battery is actually at 100%. When flashing new kernels and ROMs, its very likely that the phone will read your battery at full, when in reality its probably less. So it would seem like your phone isn't getting as good battery life (when in actuality it just hasn't been charged fully but you don't know that because android reads it as full because it hasn't been calibrated )
also, without a calibration, you might notice your battery gauge draining oddly...for example, you might see it quickly drop from 100 to 89, then drop steadily to 72, and then hang for a while at 71 (these are all just made up numbers)
so it means alot! but everybody has different methods and i've never seen anything officially released by spring or samsung to confirm methods...
I will say this though...I've read plenty about how since these Li-ion batteries don't have memory, the DRAINING method, while maybe correctly calibrating your battery, actually HURT the long-term life of your battery.
so heres what ive always done:
(the parentheses are the state of the phone)
(phone on) charge battery till LED blue
(phone on) unplug, wait till LED off
[POWER OFF]
(phone off) plug in, wait till LED blue
(phone off) Unplug, wait till LED off
[POWER ON]
When completely booted, power off again
(phone off) plug in wait till LED blue,
boot into recovery, wipe battery stats
unplug, reboot phone and use
it's always worked so try it out
Actually I'm pretty sure it doesn't fully charge to prevent over charge.. and the whole deal with you guys chargings 2-3 times after the light turns blue is just killing the life of your battery.

If it can stop at 92 percent to prevent overcharging, then it can do the same thing when it reaches 100 percent, no matter how many times you plug it in.
I don't know of many, if any li ion battery packs made today that don't have circuitry in them that prevents overcharging.
I put it in development because when you load roms, generally battery is a big concern. I cant tell you how many times ive searched for the same topic all over, I just figured it would be as helpful to others as it would have been to me had it been here and been a stickie at the top.
I've always thought battery calibration was more of a placebo effect, but I have no data either way. On a related note, here's an interesting article about battery stats and charging that was posted a week or so ago:
Android Police: Your Battery Gauge is Lying to You...
Having a battery keep at a full 100% for a long time is not good for li-on batteries. The 10% between 90 and 100% is basically used as a safety buffer. That's why the charge drops between 100 and 90 is much faster than the drops from 80 to 0. even though there ways to increase the actual capacity of the battery by using the methods above, you will still see a quicker drop from full to 90 almost instantly after unplugging the charger. I am in no way saying that those methods don't work in helping the phone read the actual charge of the battery, but they do help increase capacity a little bit. by rearranging the electrons in the battery. There actually is an article on google and on xda that backs it up. I'll try finding it

Lol.. wow alright.
Yes COMPLETELY draining a battery is really bad for a battery; infact if you do so you may end up with a 'bricked' battery.
But the phone also knows not to 'over drain' so with the method of clearing batt stats there's no harm done..actually. allowing your phone to die before charging is healthier than plugging it in before it dies.
I won't argue on the other note anymore; well simply because I don't know enough to continue just know I won't be taking that path
Sent from my SPH-D700 using XDA App
Thanks for the response. But also if you have a separate charger because you have multiple batteries, do you need to have to go through any of this? Or will the charger charge them to their true full state?
It will charge them to 100%. You'll notice it holds 100% for a lot longer.
Sent from my SPH-P100 using Tapatalk
The only thing that needs to be done to calibrate the battery is either flash at full charge or charge to full then delete batterystats, all this drain to dead and charge this way and that is pointless, though u will all argue otherwise, pointlessy
Sent from my Epic 4g
Yes thank you very much! I'm gonna give this a shot probably tonight after the Christmas Eve service and see what happens.
You should definitely add that NONE of this matters if your first usages out of the battery aren't proper. When you get the phone, you need to kill the battery before charging.. charge for 10-12 hours w/the phone off or in a dock, kill battery.. repeat 2 more times to condition the battery physically.
I've always been reasonably happy with my battery life. If I use it heavily it goes down. If I don't it can stay charged for a couple of days. Within the last week or so that has dramatically changed. All of a sudden it barely makes it through the night from a full charge to 10% or so. It also "seems" that normal use drains it at least twice as fast. Anecdotal but I know something is wrong or different.
I haven't made any changes to my phone for months. I'm running existz kernal for 2.2 and that is the only customization. I did get a bunch of app updates but that always happens. The battery use screen shows the batter is being used for display but over night, it doesn't/shouldn't display much.
Thoughts on how to find what the heck is going on would be appreciated.

What I would do if I were you is charge to 100%, recalibrate, and take the battery out for about 15 minutes before you put it back in and turn your phone on. I dunno.why this procedure worked for me but that's just a suggestion if you don't wanna flash to stock and back to whatever you're using.
Uninstall updates, then add them back, one at a time.

I notice dramatically different battery life when I use this procedure to charge my phone known as a bump charge.
1) charge to 100% or as close as your phone will get while it is on.
2) Disconnect charger
3)Turn off phone
4)Re-Connect charger while phone is off
5) Wait until the phone says 100% charged while it is off. You can check the charge by using the volume buttons if the screen is asleep.
6) Unplug charger. (This is important. If you boot your phone with your charger plugged in it can give you inaccurate battery information.)
7) Boot up the phone.
That is really odd but mine has started doing the exact same thing. I have never had battery issues and for the first time today my phone was completely dead within 6 hours, and the past week it seems to hardly make it 12 hours.
I was just assuming it was the launcher I was using but I removed it and it never helped whatsoever.

I would agree with you on that but... I really have no idea what all got updated and don't know how to find out. the perils of auto-update I suppose.

I'll give that a try... it made it through last night in pretty good shape though. Confused I am.
Not sure if this helps or not, but here is my experience.
I have two wireless routers in my house. One I keep locked to N-only and the other to G-Only. The N router I have suspected for some time has a weak or flaky radio because I can watch the signal strength fluctuate wildly over a period of 10 seconds or so. I noticed a while back that when my phone is connected to the N router it will kill itself pretty much overnight. When I disable that connection and let it connect to the G router it only loses a couple % over an 8 hour period.
I don't know if it is due to being connected to N, or if my suspected flaky router is causing it to use more power staying locked onto the signal or something of that sort.
My 727 (AT&T) is rooted stock rom. The battery indicator gets 'stuck' a lot of the time. It happens in both a widget and the default battery indicator in the status line.. They will both show 100% and I know full well that they CAN'T be at 100% after sitting around all afternoon off the charger. I restart the phone and immediately it drops to 42% ...
Anybody else seen an issue like this?
A lot all over. Do a search

what i suggest you do is calibrate the battery.
1 plug it in and charge it to 100%
2 turn off the phone and charge it until it says 100%
3 unplug and turn it on and leave it for 3min.
4 turn it off and plug it in and let it sit until it says 100% again
5 repeat step 3
6 unplug turn on the phone and use it until it hits 0% and turns off
7 plug in the phone and let it charge to 100%
now use as normal and after a few days your battery will read more accuratley and more importantly, will last longer. keep in mind your battery does lie to you but just use the phone and you'll start getting more out of it.
moving forward, charge whenever you can. Lithium ion batteries will last longer if they're charged often (like at 60%-40%).

Yeah, I even downloaded the utility that removes the battery life file, and creates a new one. I guess I need to try one of these procedures again.. I honestly think it is more to do with a bad application, no matter what the battery life meter should not 'hang', and if it does for more than a few minutes, then it should be able to recover by forcing a restart of the app... *sigh*...
This is a common issue with this phone. Look up "battery stuck at 100%" in Google and you'll find quite a few results. Supposedly it's an issue with certain chargers not giving out proper levels so it trips out some indicator chips in the battery and/or phone.

Just reboot your phone and use the stock charger and cable from now on.
I had this issue with the rooted kernel (can't remember which one) but after downloading "battery calibration" from the market and following the in-app instructions the problem was solved.

yeah battery calibration app on market worked for me as well
HW/SW specifics at bottom (if it helps)
Following the instructions provided this great site I added a custom ROM last year and for 6-8 months everything worked perfectly.
I was getting two days charge out of my battery which was is a 200% improvement. I'm not on my phone all the time.
Lately however, my phone has only been charging to 90%, and now 82% and the batt. drains before the day ends.
Using the same instructions here, I restored the phone using CWM with the files listed below (which are the same files I used originally) to restore my phone.
Everything seems to be working fine but I found a bunch of old files and app links to programs I had before so obviously I didn't do a full wipe which is what I was intending to do.
Can I restore my phone by going into CWM > Wipe data/factory reset or do I have to use ODIN to go back to factory firmware (I just downloaded I727RUXLF3_I727RRWCLF3_RWC.zip) to reset then go through the steps all over again.
Pardon the lack of terminology as I have only done this twice so I'm still new to this.
I just don't know what I need to do to get it back to stock and by stock I mean the ROM below.
Thank you all in advance. Hopefully I have provided enough information.

If you want to go back to like New condition I would do the odin process. You'll have to extract the .tar.md5 file out of the zip file you downloaded, the stock rom not the sky files. User 7-zip to extract. Put the extracted file in PDA in odin. Only have the auto reboot and f.reset checked in odin.
You'll then have to odin your recovery back on.

Thanks JD I'll give that a shot.
Condition your battery for it to show correctly. Drain battery completely till it won't even turn on. Then plug it in and charge completely with it off. Once done boot phone into recovery cwm. Wipe battery stats. Then reboot.
Make sure battery is not hot to ensure a good charge after draining battery.

First off its actually hard on a battery fully discharge it. Second wiping battery stats does absolutely nothing for the battery or the android system so this tells me you have no clue what you're doing.

Weird battery problem - charging
Ok, here's a weird one, you've probably seen before but it's new to me.
I wiped my phone back to factory stock using Vin's instructions. Followed them to a T and had no problems.
Kies then wanted to update my software (now at 4.1.2) which I let happen because I was just going to wipe it again anyways.
My battery still won't charge past 80%. When turned off, it shows 100% but the second I turn it on it immediately drops to 80%.
The battery life seems to be OK so that's not a problem.
Last night I swapped batteries with my wife's phone (factory stock SGH-T989D).
Here is where it gets weird (for me).
Her phone with my batt. charged to 100% and stays at 100% when turned on.
My phone with her batt. only charges to 80%. Again, when turned off it shows 100%.
So the battery is ruled out as being faulty I would think.
My phone has been factory wiped.... or has it? Did I screw up the wipe and leave some remnant behind?
Is there something I can install that will tell me exactly what is going on?
Suggestions?
I apologize if this type of question has been asked a thousand times but if the battery calibration is a 'myth' then I don't even know what to look for anymore.
Thanks
Try taking the battery out and leaving it out for 5 minutes. While it's out press and hold power for twenty or thirty seconds. That will discharge any residual juice in the phone. Pop the battery back in and power on.
Don't know what else to try

I tried that several different times over the weekend. I got it up to 84% from 80% but now it shows 100% charged within a few seconds after plugging in the phone while it is turned on. When I pull the cable, it goes back down to 84%.
I'm thinking of wiping it again but I'm not sure that is going to resolve the problem. Don't know what else to do/try.

Don't ever do this. Draining your battery below 15-20% is actually bad for it, as the heat generated by simply charging it while idle does damage. It's also been shown that the lower the depth of discharge, the more cycles your battery will have in it.
Also, Android devs who work for the big G have said that battery stats are essentially meaningless in this generation of phones. If you do calibrate your phone, don't run the battery all the way down. Get the 100% baseline, then use it as normal.
Download the battery calibration app. I believe Skyrockets max out at 4330 mV, but I could be thinking of the Note II. If the battery calibration app shows that you're in that neighborhood, who cares if the meter says 100% or not? You're getting a full charge.

Can you recommend a battery calibration app?
I did swap out the batteries as per the post above. I was thinking of charging the wife's batt. to 100% and putting it in my phone. Then do the pull the batt. for five minute trick. At this point it's all about the hail mary.
I'll keep you posted
Update: HAHA! Just gets better and better. Downloaded two battery calibration apps. Both say to charge to 100% before operating... FML.
I use Battery Calibration. It shows the mV along with the charge level. If you're charging to 4100 mV+ when it freezes at 81%, you're doing ok. If you're only charging to 3000-some mV, your battery's borked.

Been testing a few things. I charged my battery to 83% (full) and put it in my wife's phone. It registers as 100% so it's not the battery.
Yeah, I could live with it but it bugs me as I'm sure it would bug you too!
The problem I'm running into is when I put the battery back in it goes to 83%.
I installed two battery calibration tools. Both called 'Battery Calibration' One says it can't operate until the battery is charged to 100% so I'm screwed there.
The other one says my phone needs to be rooted. I thought I had already taken care of this but I went through Vincom's steps again to root (just to be sure) and now I routinely get a "E-signature verification failed"
The CWM (ver 6) doesn't give me the option to apply from external card, nor does it have an advanced section. I think I am going to wipe the phone again and use the old CWM.
===UPDATE===
I ended up wiping my phone again, going back to CWM 5 and SKYICS 4.2. Wiped everything and voila. Battery is reading 100% again.
Thanks TJ for your assistance and patience.

Isn't it a great feeling when a potential hardware (e.g., $$$) issue turns out to be a simple software fix?
