[Q] SGS2 suddenly crashes - Galaxy S II Q&A, Help & Troubleshooting

Hi everybody
Since one week or so, my phone suddenly crashes for no reason. I'm just typing some message in WhatsApp for example and it crashes. No other apps are running, besides stuff like facebook and avast mobile security. When I try to power it on again, the battery is at about 1% or so (dropped from like 90%!!!) which means, that the phone turns off again very soon.
I can repeat this very often by now, so this phone is at the moment quite useless.
I found out that this doesn't happen, when the phone is charging or connected to PC. When it turns off and I connect it to the PC or charge it, it has about 70% battery (before more than 80%). So there is also a battery drain, but not that high...
I'm running Slim Bean 3.1 with no changes at the UV/OC-settings and other Kernel-settings and stuff. No other Kernel installed than what Slim Bean does.
So my question is: What can I do? Is my battery broken or is it something else?
I bought it like 1 year ago, so I can still send it back.. Just in case the phone is broken.
Oh, i forgot to tell that I can still go to Recovery or Download-Mode. If that might help...

Weird stuff you got here...
I think there's an issue with the battery chip. The sgs2 has a chip that calibrates the battery without the need of an app (although it takes several times to completely calibrate your phone) and if it's broken the phone will think the battery is dead when there's in fact a lot of juice left or overestimate it.
The best way and what i'd do if you still have your warranty is to reflash the stock rom (the one that was on your phone when you first bought it), use an usb jig to reset the flashing counter and then send it to samsung.

The crashing stuff... Try fixing permissions from the recovery. Wipe caches and data for the apps that crash.
As for the huge drain in battery (although from 90% to 1% is most likely an exaggeration, but i get the point ), it's normal.. Usually happens when you reboot at <= 40% battery, but can occur at higher percentages too... Its a hardware thing... No solution... Only thing is that if you use extweaks/stweaks there is an option to reset fuel gauge, which I believe does something

Lol... Its because of the faulty fuel gauge. I've gone 20% up once because of it

lol, we can tell our iphone friends that sii invented wireless charging

Sometimes it's bad when be 50% and then suddenly after reboot went to 15% or good like today form 10% to 54%
Merry christmas and Happy new year

i have had this very same problem this is how i fixed it however bare in mind i am running stock 4.0.4.
first charge your phone to 100percent
backup, backup, backup a nand backup is always a good idea
go to recovery and clean you battery stats, clear cache, clear dalvik, fix partitions "do not delete the actual rom on the phone" also before doing any cleans if your running 4.0.4 do research because the stock kernel combined with cleans from recovery will BRICK YOUR PHONE
reboot the phone
turn the phone off and remove the sd card
turn on the phone, go to settings / storage, perform a format usb storage, next go to backup and reset and perform a factory reset.
let the phone reset.
this should fix your problem.

Hi there guys,
First time here.
My problem is similar and for the ones saying the we are exaggerating I can tell you we are not. I have prints but I dont know to add them here with the app.
So the problem, my S2 is using samsung rom for android 4.0.4 (the oficial one and the phone is not rooted). And the phone crashes when under stress and the battery goes from wherever the level is, from 40% to 90%, to 1%. Then if you let the phone off for like 20min it recovers to like half of what it had before crashing.
What I mean with under stress is normal things such as browsing the web.
One thing to notice is that if the phone is connected to the charger it doesnt crash ever. Does that mean that the battery is faulty or is that controller chip? Should I send it to warranty?
Thanks all and make me less of a noob =)

Sudden shutdown and Sudden battery drain

Hi all, I have a very serious problem here. Please help me out.
Whenever I am using my phone for more than around 10-15 mins continuously, even though battery is around 80-85%, I lose network all of a sudden, the phone flickers or flashes or blinks for a moment and shuts down all of a sudden. When I try to boot it again, it says battery low and many times, it wont boot only. When it is about to be botted only it gets turned off. the solution is to connect to charger when it shuts down. At first, on connecting, it shows zero battery, and immediately battery level will be restored to the previous level, after blinking again in the charging screen and then only I can turn it on. What is the issue?
I also tried wiping data/factory reset.. Wipe cache and dalvik wipes repeatedly. Tried many roms like resurrection 2.6, 3.01, XWLPM stock rom, Salman ROM, etc. The same issue happens in all the roms as well.
Somebody do reply!

That sounds serious, have you tried sending it to the customer service? It's helpful if you're still on warranty..

well do one thing- try flashing another kernel too- anything will do - siyah maybe. 1% chance of it working..
and if it doesn't, what this means is that it is most probably a hardware issue- and you would need to get your phone checked in the service center.
Have you tried a different battery?

Maybe battery failure! try with a different battery if no change and everything was like before then I suggest you to send it to customer service as soon as possible.
Same thing for Stock
I experienced the same thing on Stock samsung unrooted rom 4.0.3
I suddenly found that my phone is not responding and is heated up too much, I quickly removed the battery and after letting it to cool off restarted it.
Was amazed to see battery came down to 20% from 80%, Post this incident it is working fine
Now I have tried multiple kernels and Roms and it still is working awesomely on everything I throw at it

Thanks for the replies
Turns out its some battery problem. I swapped mine with a friend's battery. He is facing the same issues now and I am not facing any issue. In ebay and flipkart, it shows original battery costs just 559 Rs(around 10$). Is the original battery available for such a cheap price? Or is it not genuine?
It sounds suspiciously cheap.. mmmmm. You should try going for the legit 2000mAh from samsung longer battery life haha so much win

Hi yashwanthms,
Just to let you know, currently I'm facing exactly the same issue.
During or after using camera, gps or usage of data, the screen flickers and then after a few seconds it freezes and shuts down. Switching it on doesn't work, because it thinks the battery is dead while still having 50% left or something like that. It does however work when it is plugged into power.
Thanks for your reply of your battery replacement. I will try the same thing and see if it works out.
Still a question though: did you buy a new battery and what were your results afterwards?
Kind Regards,
Ahsimmis
same issue here
After reading above posts, I'm sure it is a battery issue. I use hotspot and GPS a lot which is why I've to charge a lot and charge while docked to car cigarette lighter too, no wonder the battery didn't last more than a year. Will buy a new battery tomorrow and post the result here.

Like others said, I think it's battery problem. Do not use cheap unreliable batteries, nor leave your phone charging after 100% charged for a long time. This would affect your battery performance. Experienced that using my back-up battery, from 25%, sudden shutdown. My original battery would alert me first "Battery is now low, please recharge now". The back-up won't.
This is to confirm that I've purchased a new battery from Samsung franchise store. It is doing fine.
Cost me Rs.800 which is like $18. The store didn't have any retail battery in stock but they provided me one from one of the phones on display. I'm not sure if I did the right thing by taking it but I needed one badly and none of the stores I went to had any in stock for retail (there are like 15 of them in a 2km radius)
This is happening to both mine and my wife's Galaxy S II's. Screen flickers, shuts down, comes back with zero battery, plug it in to charge for a few minutes, suddenly back to ~80%. I've also found the phone is hot when this happens, pulled the battery and its NOT the battery that is hot, the phone itself is (feels hottest right below the camera, just above the battery port).
I ordered a replacement battery for her and it cleared the issue for about 2 weeks but now its happening again. The replacement was a genuine Samsung OEM, same maH, same part number.
My phone is rooted with a custom ICS kernel, her's is factory ICS.
I've ordered a new battery for my phone too to try, but I'm not convinced its solely a battery issue.

I have the same problem, change the battery with new one but still it happens & I am afraid it may be hardware!
Phone is not root & running official rom 4.0.4
I have changed battery and now it works ok. But yesterday, the phone freezed and became very hot. I rebooted it and then the battery level decreased high. After that it works ok again.
same problem
hi there,
I am having the same problem as on the OP. Have already ordered a new battery, because my warranty expired on sep 15th and I was on holidays outside my city and without the invoice
do you have any feedback about changing the battery?
thanks.

[Q] Charging issue

My problem is kind of strange.. when I turn off the phone, it thinks it's being charged (no cable plugged in).. and i'm unable to boot the OS as per usual. The only way for me to do it is to load CWM and choose the reboot option, which does work but only with 1 battery (a spare hyperion one). The stock battery and my other hyperion aftermarket battery does not work. Instead, it takes me to the stock recovery system.
I tried remedying this problem by doing wiping battery stats, but it doesn't help any. I also decided to make the jump from unnamed ROM (gingerbread) to an ICS rom (AOKP)
On top of that, the phone no longer makes a beeping sound when i plug the cable in, but it does charge the battery.
Another thing: the boot screen (when turning phone on) shows "samsung i9100" when i'm pretty sure my phone is an i777.. i might have done something to this phone when i got it about 10 months ago, but i don't remember. All i remember was rooting the phone and flashing it to unnamed ROM.
It seems like this might be a hardware issue, but i'm no expert.

I would try wiping cache and dalvik cache in cwm. Also, fix permissions in cwm. If that does nothing, I would try a different kernel. However, this may be an internal issue of the phone.

Well you fixed your charging issue by itself It says that because the flash counter has been tripped. Just use any triangle away app from the play store.

i just flashed to AOKP ics rom yesterday from unnamed ROM, so i doubt it's a a kernel issue. just tried wiping cache, dalvik cache, and fixed permissions. still the same issue. im afraid of shutting the phone off or changing the batteries now, which is a pain since the new ICS rom burns battery power like crazy.

the flash counter isn't a big issue for me; thought i had circumvented it when i flashed the ROM 10 months ago, but i guess not. the phone still thinks it's being charged when it's turned off though. that's my main problem.

Try to go to stock and see if the problem persists. If it does obviously a hardware issue
ultimately, if i really want to confirm, i'd probably have to do that. but i've already installed 2 different ROMs and the issue is still persistent, so i'm just going to assume it's a hardware issue. it also seems now that the phone no longer turns off. if i choose to turn it off, it'll just reboot the phone. this phone will have to last me another 9-10 months, i just hope it doesn't die out on me.
but yeah, i tried ICS for about a day and didn't like it. bad battery life, seems slower, and less user intuitive UI.. so i'm going back to gingerbread.

you know samsung has factory warranty for that kind of stuff.
i got my phone refurbished, about 9 or so months ago.. it only came with 3 months for the warranty. i guess getting a returned phone ended up biting me in the ass.
now the phone is overheating when im charging it.. looks like it's going to crap out on me soon.
Download the stock 2.3.4 firmware from the download repository. Do a full wipe including system data cache and dalvik. Boot into download mode hook up Odin and flash the stock firmware. If its a hardware issue your problems will persist in which case u could sell it on eBay for parts. If its a software issue that will fix it.
Sent from my SGH-I777 using xda premium
that's what i'll probably have to do tomorrow. if i remember correct, rooting the phone on 2.3.4 wasn't that straight forward, so i'd have to read up on how to do that again. but im just gonna leave it as is right now.
the phone acts really weird. when i took out the battery and replaced it with another one, it would keep doing the same thing. so then i plugged the phone into the USB charger and tried turning it on - that worked.
if it's a hardware thing, it's got to be something to do with the battery sensor. the phone is simple to remove, so i wonder if i can replace it myself.
i believe my phone is now semi-FUBAR.. it still runs, but seems like the battery sensor issue is a hardware one. i just tried doing a stock flash/odin thingy, and it still has the same issues... also, the phone is now permanently showing as MTP connected. i am also seeing decreased battery life.. only lasts about 1/2 a day now.
i guess i learned my lesson.. don't switch out the batteries too often, or your phone will die.
Another thing: the boot screen (when turning phone on) shows "samsung i9100" when i'm pretty sure my phone is an i777.. i might have done something to this phone when i got it about 10 months ago, but i don't remember. All i remember was rooting the phone and flashing it to unnamed ROM.

is this a big deal? i'm also having samsung i9100? im using ucle5 AJ's rom/kernel.
i'm also having issues with charging the phone. it seems to charge forever, i have to unplug and plug the charger again to properly charge it.
When it says i9100 it means you tripped the flash counter. If you want to reset it use a triangle away app.

i see thanks.
i'll try to run this app and see what will happen.
do wiping battery stat needs to be in full charged? i used to do that on my tab so i guess same principle applies.

[Q][help] S2 randomly shuts down

Hi. I have a very frustrating issue I hope someone can help with.
Over the last 3 days or so, my s2 has started to randomly shut itself down. It only appears to happen when I'm using an app, nothing specific, it can happen anytime.
The battery level has been anything from around 75% to 30%.
Sometimes when I turn it back on, the battery shows I am at 1 or 2 %, making me think it might be some kind of calibration problem, but I've tried the suggested method to no avail. I've also completely fresh installed the Rom I was on (neat Rom) and tried another (disaster Rom) but the problem remains.
Can anyone suggest what could be causing the random shut downs?
Thank you
Karf
Are you undervolting/ under clocking this can cause a sod
Hi. Nothing like that, just used neat Rom or disaster Rom as they come.

Your phone(battery) has insane gauge chip search for this it answer in your question(it's only for battery)
Happy new year
Paulius
Hi, thanks for the reply. I'm not sure my issue is to do with the guage chip directly, as my phone will switch itself off at any battery level. The issue designed in the other thread its having something like 56% and then having a much lower value after an intended reboot.
Shutdown it's called sleep of death( scary name) but it not death it's just sleeping forever... it problem with your kernel and battery problem is insane gauge chip...
Happy new year
Paulius
I've just charged to full charge, unplugged - and within 2 minutes, the phone froze, could not do anything - so i pressed the power button until it went off, and it booted back up again without me doing anything - when it booted, it showed i had 2% battery. Then it did the same thing, froze, i had to reboot - then it showed 37% battery.........no idea what's going on apart from maybe a faulty battery...
Buy new battery. It was here on the forum a few times.
Yes. When phone hot(sometimes not) it take battery about 50-60%(I don't know exactly) but sometimes it add battery...
If you flash siyah kernel with stweaks(5 version) you can reset it but chip do funny thing even you reset...
Happy new year
Paulius
try Battery caliberation app ...
if it doesnt work buy a new battery
What are you talking about ? It's not battery Fault it's Insane Gauge Chip.... And Battery Calibration not helping...
I decided to go the whole hog and go back to a stock unrooted ICS, after wiping everything, then CFRoot - then reinstalled Neatrom light - currently restoring apps via Titanium - fingers crossed...
I think you don't have anymore BSOD But if you have flash Syiah kernel
Try new kernel and reset fuel gage
Try installing a new kernel like siyah or dorimanx and then reset your battery log this should resolve your problem if not buy a new battery.

I think I have a very similar issue. The randomly reboots happens several times a day, it does not happen though when charging (never). By now I'm on jb leak and still have the issue. When it shuts down, the sreen dims a bit and then it's gone, the weird thing is that often I have to pull the battery or charge the phone before reboot is possible, the battery shows different values after rebooting, sometimes close to what was before (especially when rebooting on charger), and sometimes way off the values before. I came initially from slimrom with siyah or dorimanx kernel, I really hoped jb leak would help (also tried different kernels), but it didn't. It also seems to me that it happens more often with the sd card (32gb) and without the phone seems more stable, but still it happens from tme to time. Once the screen dim (only one or two steps) and shut down even happend when in CWM recovery, is it maybe hardware related? It's very hard to find the source of the problem, anybody else experience similar issues? By the way the shutdown I have is not a proper shut down, the phone doesn't show the message "is shutting down".
I've completely wiped, used Odin to go back to ics stock, installed cfroot, then installed neatrom light. Had the same issue, so I've installed siyah, and used stweaks to reset the battery fuel gauge. I've only been off charge for 10 mins so far, but normally it would have shut down by now, so here's hoping...

Update - battery was at 89%, and the phone shut down, when rebooted, it showed 28%, then when plugging in while it was shut down, the battery icon showed about 50%. Like a previous reply, it never happens on charge, so it does appear that the battery is knackered, time to go shopping I guess :-\

I had the same problem - SOD several times a day. I change the batery with a fresh new samsung 2000 mA one.
Unfortunatelly SOD came back, but I found a trick: turn off WiFi. Use it only manually.
For the past 3 months I succeded to have 0 SOD's.
I know that manual WiFi is a setback but it works with those experiencing SOD.
Hope it will be usefull.

My vibrant turns off by itself and it's unusable

Secuence of events that happened BEFORE the problem started:
1-Had a working rom of CM7.2
2-Battery was going out too quickly (7 hours or so) therefore I tried wiping battery data
3-Charged the phone
4- Unplugged it, took a picture
Problem:
One hour later I realised it was turned off...
I turned it on again, it turned off soon afterwards
for a moment it had a problem turning on (it wouldn't go past the cm logo)
afterwards it was even worse; it turned off before even passing the first logo, I couldn't even get it to recovery mode.
Solution Attempt no.1
Tried to get it to stock rom with Odin.
I was able too... but the problem persisted in the new Rom.
Solution Attempt no.2
Tried to get another rom
My situation NOW
I'm back on stock Rom. If I leave my phone alone for like an hour or so it works for 20/30 secs before turning off... After that the problem gets worse till I cannot boot.
Any ideas guys?
How old is the battery? There are apps on playstore to check your battery, thats where I would start. It doesn't sound like a Rom problem, sounds like hardware.ie battery first. Gluck.

Can't have the phone on for 1 minute, forget about downloading and using an app from the store...
I don't know if it's a hardware problem since it happen really suddenly...and just the day after I resetted the battery stats ..... Maybe it is a hardware issue but I want to be sure I tested everything first
Hey, maybe you moved on but I was having the same issue on every ROM.. stock or not. being the detective I am I investigated and inspected.
One of my battery connecting pins is loose even though it's pressed tightly in the case any moderate amount of force or impact loosens it from the contacts.
My temp solution for you would be to add something to the back cover to apply enough pressure to keep the battery still or resolder the copper connectors. The first being easier.
Hit thanks if that helps.
Invest in a new battery. Simple solution.

Nook Tablet shutting down for (what seems like) no reason, over and over.

Hey I seem to be having some trouble with my Nook Tablet. I've got the 16gb version, bought it within the first month or so of the tablets getting released. It's been running fine, i have it rooted, ran cm7 for the longest time on it, switched to cm10.1 more than a few months ago and everything was pretty great, then crap started going downhill.
I noticed that when my battery would get down between 20-30% it would just shut down. The low battery screen would come on for a split second before the "tablet is shutting down" screen would pop up in front of that and it would shut down.
Now, since then it's been happening more and more. When it's at anything lower than 96ish% it'll happen. But it's got some weird symptoms.
- The screen freaks out. Like there's 100 fingers on it pushing a ton of crap at once, when I'm not touching it at all. it's sensing a bunch of false touches that usually ends on the Google Now screen before getting the same old low battery, then tablet shutting down notifications.
- It only happens when it's running on the battery. It's never ever happened while it's plugged in.
- It only seems to happen when the wifi is on. If the wifi is off and i'm at home just reading a book or something, it'll drain all the way down to 15 or whatever before telling me the battery is low, I plug it in, all is fine. If the wifi is turned on the freak out happens.
- If it starts freaking out and I plug it in while it's happening, 1 of 2 things, It either completely stops and everything works fine, or it just turns off dead right there, not shutting down, just turning off.
- I HAVE had it drain pretty low (around 23ish) with the wifi on, but it did do the same freak out thing once it got there. It just seems to be so random when it happens, any time the battery is between 15 and 96%.
- If I turn it back on after a freak out without plugging it in first, it will restart fine, then last about a minute or 2, freak out again and shut off. If I turn it on again after that it'll do the exact same thing. And if i turn it on again after that it'll get to the CM10 boot screen, just about to where it's going to go to the lock screen, then boom, makes the beedoop battery sound and shuts off without ever actually showing the lock screen. THAT happens everytime just like that. If I plug it in first and then turn it on, it runs fine.
I've tried factory reset and reinstalling and all that stuff, nothing seems to be working. I even started from scratch not letting google or titanium backup restore my apps, completely formatted and wiped the sd card when reinstalling, nothing seems to be fixing it.
Basically this thing is useless without being plugged in. Ive even lost a 32gb sd card because of it's constant just turning off screwing it up (i'm guessing) since it's not being properly dismounted or whatever before being shut off. That card cant seem to read/write anymore. I now have a 16gb in there I'm hoping wont get screwed up because of the same thing (although I'm sure it will eventually if this isnt fixed)
Is this a battery issue? A hardware issue? User Issue? Can anyone help? I can provide any information you might need.
I've been searching for months trying to find an answer, but the symptoms are so weird I cant find anyone having the same problem as me..
Also, my fiancee also has the same Nook tablet, bought them the same day, rooted and hacked them the same way that day, and put CM10.1 on both of ours the same way the same day, hers is fine, mine is acting a fool. (I also use mine about 1000x more than her though, I use mine for EVERYTHING, EVERYDAY, she reads Sandra Brown books and watches YouTube movies once every month and a half)
Help? =[
the finger touch thing at random on your screen without touching it is your charger cable , its a crap cable , i had this happen to me too , B&N will swap the cable and charger for free, i highly suggest you do that and get a new one swapped , mine still has issues , when its plugged in and charging , i sometimes cant use the touch screen , its the charger , they are like 1 in 3 garbage and cheaply made ,
take it to the store they will swap the charger for free, if they hassle you ***** up a storm , they are supposed to just swap them , its well known fact the cables are cheap garbage and not easy to get new ones that are not garbage, i use micro usb's it takes longer to charge but i get quality cables from amazon cheap as piss 2.49$ if you want the link ill find it , again takes longer to charge , but i no longer have touch screen issues and can use tablet while its charging ill re read the rest of your post and make an edit if i can help on anything else
spyder
how long are you charging it for at any one time ? i do believe if my memory serves me right , theres a problem with the battery level on both cm 10 and 7 , seven is way worse, the battery level is not reported correctly , its being worked on by better minds than ours , im sure one of em will chip in here shortly ,
if i were you you have cynoboot installed to emmc ? i would turn the thing off completly , and charge the **** out of it , with a good cable , id use your girls cable it sounds like she got a good cable. like leave it over night charging on hers while you sleep , then in the morning boot it check the batt level in cynoboot and then in cm10.1 , im keeping mine juiced up , last time it died it ended in a boot loop that i had to unplug the battery to fix , most people dont want to crack a case even though its easy peasy ,
again , try her charger , if your powered up check how long it takes to charge fully it should be 6-8 hours on the nook 2.1 amp factory charger , i think you need a new charger though , i would try to swap cables until i found a good one , then look at ipad travel charger they are 30$ , but they output 2.1 amp and apple crap is quality which is why its 30$ , or look for a samsung galaxy tab charger USB output 2.1 amp ,
Ahhhh.. see. The battery level being reported wrong makes sense for why it happens so randomly. Another interesting thing you said was it should take 6-8 hours to charge with the stock charger, mine was reporting 100% battery after 2.5 - 3 hours charge time. This could be the problem.
I did what you said, let it charge overnight, and it did the same thing, but, not until it got down to 32%. Which is better than 82% shutdown.
When I get home tonight ill plug it in immediately and not touch it until tomorrow morning, well see what happens. Thanks for the response.

I may have figured this out. I switched my rom to aokp 4.2.2 and then flashed the showtime kernel, set cpu tuner to no more than 999mhz and all seems to be running fine. Bbs says 14hrs on battery, deep sleep for 9 of them, and I'm at 69% battery now. (Bbs started collecting at 91% for some reason instead of 100%)
I flashed the rom yesterday around 6pm, let the battery go all the way down to the first time it randomly died, then just charged it back to 100% and I've had it off the charger since then, 14 hours now according to bbs. Ill report back if it freaks out or something later.
Edit: turns out this didn't work.

Just did it =[ freakedout and shutdown at 77% battery, then got stuck in a bootloop.
It ran fine yesterday, I was watching podcasts on it no problem. Charged it last night and now today it seems unusable without being plugged in.
Does anyone have any other help they can offer?

I might have a solution for the battery problem. Do you have any microUSB chargers lying around? maybe for an old cellphone? If you do, use that to charge your Nook Tablet. It works, but it's slow, takes 8-9 hours for a full charge (5% to 100%) @ 500mA current. My old Motorola flip phone's charger supplies 5V @ 550mA. I'm pretty sure you have one of those lying around in the attic or garage. Anyways, let the NT charge to 100% using a microUSB charger (not the Nook Tablet's stock one, the cable is faulty and I am sure of it).
Once it's charged to 100%, go on YouTube and watch a few videos. If the battery goes down steadily, that's good. If it goes from 100% to 80% or less suddenly, there might be a problem with the battery calibration or the battery's going dead.
I bought a Nook Color off eBay that the seller listed as broken, except it wasn't. The battery was simply dead beyond the capability of the Nook's stock charger to revive it. I used the old Motorola charger. It took 10+ hours, but finally my Nook Color booted up, although with 18% battery life only. No matter what, it would stay at 18% until it shutdown without a warning. The solution to this was to delete a file called max####.bin in the /rom partition, then reboot.
Steps to recalibrate the battery (ONLY try this method if you're sure the battery needs to be calibrated):
Open the terminal (once you are 100% charged. You'll know this if the power adapter isn't warm anymore)
Type in "su", allow root access for once
Type in "cd /rom"
Type in "ls" (that's a lowercase L and S)
Type in "rm max#####.bin" (where ### are the numbers there)
Type in "exit"
Type in "exit" again
Hold down the power button and reboot. Once it reboots, it might show question marks on the battery meter before going away shortly. Hopefully, your battery will be successfully recalibrated.
Hope that helps.
Thanks a lot for the reply. I definitely have a charger lying around so ill try this tonight when I get home.

Any good news? Did you charge it up?

Just got done testing it out. I charged it for about 16 hours, pulled it off and powered it up, my battery status said charged, then 100, 99 etc. Once it got down to 87 it freaked and died.
The battery did drop way fast though. Like 100 to 87 in under 15 mins. Not instantly though.
If you search "nexus 7 phantom touch" on youtube, you'll see exactly what my nook is doing, only difference being the nook dies after about 10-15 seconds of the screen freaking out. And it ONLY happens when not plugged in.
If my battery calibration is off, would that mean maybe it could actually be around 15-20%, even though its reported as 100%, and not letting it charge passed that? Or is my understanding a bit off?

Right. My Nook Color was showing 18% charge no matter how charged or discharged it was (until I deleted the max#####.bin file).
Try what I said, delete the max#####.bin file and reboot. That will recalibrate your battery. If after that it still shows the battery draining way too fast, that means your battery is going dead.
Ok, so I reset the battery stats and now I'm seeing this.. this doesn't seem right at all..
I let it hang out for a while and it did the usual freakout/shutdown when bbs said it was at -22%, android showed 69%.
I think ordering a replacement battery or finally just getting a nexus 7 is the fix at this point?

Or actually, you might find "for parts" Nook Tablets on eBay for <$30. I would use the battery in there instead of buying a cheap chinese made battery (which are always of garbage quality, not to mention dangerous). You could also use a Nook Color battery in there, but you'll trade off 3 hours of usage time. Nook Color batteries on eBay sell for $7 used, but genuine.
Before you buy anything, try doing a complete wipe and reflash of CM10. Boot to CWM > wipe battery stats, wipe data/factory reset, wipe cache, wipe dalvik cache; advanced > wipe system partition; go back > flash CM10, flash gapps, flash CWM (if not already installed).

Awesome, thanks for all your help man. One more thing, I'm running CWM recovery v. 6.0.2.7, there's no wipe battery stats option in advance (or anywhere else I can see). Is it hidden somewhere I'm not looking or not in this version? Is there a newer version I can flash I overlooked?
Btw, http://www.newpower99.com/Barnes_No...cement_Kit_p/barnes and noble nook tablet.htm this was the battery I was looking at for $40, but the used nook from ebay seems like a better idea. (Cheaper too, which I like)

The CWM I used was a bootable microSD one. It had the option to wipe battery stats. At best, it will recalibrate your battery, nothing else.
I followed Ray Waldo's instructions (he's really good at explaining things in non-technical language). Download link also posted there.
You can use any Linux distro with GParted installed to set the boot flags on the card. (I highly recommend Debian, been using it for 4+ years).

I wouldn't buy that battery off the newpower site. It's a scam. You'll get a really crappy battery (3200mAH, probably chinese made, and unreliable). I would much rather buy a used GENUINE battery for the Nook Color or Tablet than a cheaply manufactured one (selling for an unreasonably high price).
If clearing the battery stats and doing a full wipe and reinstall doesn't help, I would buy a Nook Color battery for $7 off eBay. This is the last one supposedly (doubt it) http://www.ebay.com/itm/Nook-Color-...863?pt=LH_DefaultDomain_0&hash=item27d5fc185f
^^It's genuine, has a 4000mAH capacity, compatible with both the Tablet and Color, and wont explode in your face. (You really don't want to take chances with cheaply made chinese li-ions. Look on YouTube for li-ion fires/bloat (expansion)/explosions, not pretty). Be sure you also have a Torx T5 screwdriver to open up the NT. If you don't, order a set off eBay. (P.S. Don't get the chinese made ones, they're cheap and they don't work. Get a set from Craftsman if you can, those have a lifetime warranty).
Gotcha. Will try everything you mentioned and if no luck ill hit up ebay. Thanks again for all your help (and saving me from a potentially harmful choice of battery)

Have you have made progress?
Also, let me know if the battery (if you ordered one) works well. I think my Nook Color's battery is about to kick the bucket. It takes like 15 hours to charge from 15% to 100% (compared to 8-9 hours for my Nook Tablet, using the same specced charger).
My 16gb nook tablet with CM10.1 is doing the exact same thing as yours. Random touches and sudden shutdowns. The OS does not know how charged the battery is. I am eager to hear your results.
