[Q] Rooted Motherboard Issues? - Galaxy Tab S Q&A, Help & Troubleshooting

Knowing that this is my last resort and with all the wonderful knowledge here on the forums, I'm hoping I might get some creative ideas.
I recently bought a Tab S 8.4, rooted it about 2 weeks after I got it. No problems, everything is working great. Last week, the screen starts to flicker and the tablet reboots randomly. When it does this, the battery goes from 100% down to 12%. Eventually this happens enough where the tablet won't stay on for longer than a minute. Read around the forums and find others mention the exact same issue. Potentially a battery pull/re-plug may alleviate. Tried that to no avail.
I have found that if I hold the battery plug in place *real* tight, by pushing down with my finger, the tablet operates somewhat normally. Could be a motherboard issue.
Anyone run into this at all? Thoughts? Ideas? Replacement parts? I've got a $500 brick on my hands now with no warranty to boot. :crying:
Thanks in advance!

I soldered my battery straight to the board. But before doing that, try spraying some contact cleaner (found in hardware stores) and see if it Will work

hey, i got this issue once ! go to customer service,they will fix it for you in 5min FREE !

So they took off the back cover and soldered it back in for you for free with no warranty? I'm a bit surprised they would do that. I'll have to see if I have one in my area.

Please keep us updated

I found a local electronic repair shop that said they could re-solder it for me relatively easily. Brought it in and he said it did look like the terminals on the battery plug had been pulled back a little bit and weren't soldered on there very good (good to hear some type of confirmation on that and he let me view it through a microscope as well). Twenty minutes and twenty dollars later, my tablet is working as it did previously. I've used it sparingly over the last 2 hours, so nothing definitive yet, but the fact that it doesn't restart right away makes me think the issue is resolved.
Thanks everyone for the suggestions!!

Battery Results
Just wanted to follow up with everyone that might be experiencing similar issues. After fixing the issue, and de-bloating a bit, my battery life is phenomenal. Much better than when I first got it. I suspect the battery issue was causing some drain as well, even when it wasn't restarting. The attached screen is still with 35% battery left.

Thanks to all those who contributed to this thread. I too was having battery issues. I'd get random restarts, disconnects from the cellular network, forgetting wifi passwords, battery that would go from 50% to dead in three seconds., display glitches etc. I finally opened up my tab which I thought was going to be a pain but was actually pretty easy. By naked eye the solder joints looked fine but under a microscope I could see that all six solder joints on the battery connector were cracked and by pressing on the connector could see the connector move independently from the PCB. Resoldered the joints and everything is good now.

Well my problem is that the battery isn't charging, I get a battery with a red "X" mark when the screen is on but when it is turned off, its charging well but very slow and when it reaches 99% it never goes to 100%. Could it be possible I have the same problem as you guys? no random restarts for me just the issue of sucky battery life (3 hours on wifi) and not charging

Are you using the stock Samsung charger? Just plug it into the wall and it should be fine. Don't charge from the computer or use a different charger

Got that same problem. My tab will only charge up to 60% under 6 hours. Batterystatus app shows that my 2amp wall charger is just charging at 300mah +/- . Tried my power bank, same issue. Changed the cable and the reading from the wall charger is 1800mAh , could top up the battery in 2hrs

Using wall charger. Never charged via pc...
Any Ideas?

I have experienced this. Flickering of the screen which eventually leads to reboots. Got it fixed at a samsung service center. You rooted it but you're on stock ROM right? I think there's a problem when we root it and stick with the stock ROM. When I rooted my tab again, certain apps started FCing which lead to lags. So I'm gonna wipe this and start from scratch.

[Q] Imported Galaxy Nexus hard brick

Hey all. I now have an imported Galaxy Nexus that won't turn on, here's what happened...
I bought the phone back in April and haven't had a single problem with it until now. On this past Monday I woke up, got ready for work and unplugged my fully charged GNex from my wall charger as I do every morning. On my way to work I popped my GNex into the Samsung car dock to listen to music as I do every morning. When I got to work I popped out my GNex from the dock and sat at my desk for a while. I went to check something on my phone and it felt kinda hot, I thought nothing of it and kept working. Maybe 10 minutes later I checked if it was still hot and it was, uncomfortably hot, and the battery was at like 40% (this was about 40 minutes after I took it out of the car dock).
This made me think that by some chance a program was running crazy in the background, so I restarted my phone. Booted back up, plugged it into a wall charger I have at my desk, and let it sit for about 10 minutes. I then picked it back up and it was still burning hot, now I shut it down again, unplugged it, and pulled the battery out until it cooled down (about another 10 minutes).
Now I popped the battery back in and booted it up. Starts to get hot again and now the battery is at 4%. At this point I think "WTF..." and turn the phone off and let it sit there with the battery in. Keep it in there until the battery completely discharges (the phone isn't hot anymore) thinking that maybe it's having trouble reading the battery stats idk no big deal right? Turns out no, very big deal.
Let it sit there for an hour with no battery in it, then plugged it in and tried to power it on. Nothing. Pulled the battery, popped it back in, and let it sit with the charger in it for 30 minutes. Nothing. The phone isn't getting hot at this point like it was. So I try all the button combinations with the volume buttons and power buttons and still nothing. Even when I plug the phone in the charging battery animation doesn't show up.
When I leave it plugged into the wall charger now, the phone gets a little warm as you'd expect when you charge your phone, not hot like before. I took the phone apart and saw nothing wrong with it, but then again I'm not a hardware guy so I took it to a phone repair shop. He took a look at it and couldn't find anything weird with it either (besides it doesn't work).
In this mess I tried to contact Samsung and take advantage of my "International" warranty but no dice as I'm sure most of you know (this is my $450 lesson). Samsung USA said they won't even fix it if I pay them, I have to do it through Samsung UK which is a nightmare.
The last kick to floor was seeing my credit card charged for the desk dock that I ordered a week before the day this happened. I've ordered a new battery on the off chance that maybe that's the problem, if not I'll be buying another GNex with a US Warranty from the Play Store.
Any bits of hope anyone has for me? Is it even worth my while to ship it off to another phone repair store that says they can "fix it no problem"? Sorry for the long post, everyone always says to post as much detail as possible so I did!! lol. Thanks for reading!!
In the same boat, my Nexus just died today. It is completely unresponsive. Plugging the phone into the computer with no battery will not display any OMAP hardware.
hmm I'm wondering now what is the reason? is it 4.0.4 update? my phone is getting warm after the update too, and the cpu consumes 30% power. but its not too hot, only one area, on the virtual SD card area.
where did you order your GN from? depending on which website... they may "fulfill" your warranty if you're within their warranty time frame.

Off an Amazon retailer, I already checked and they said no :-( I should be getting this battery soon, hopefully that fixes it. I highly doubt it though.
Good news, the website I got mine from(Dailysteals) is willing to do an exchange or refund for me. Surprisingly, I didn't even have to go through a lot of trouble for them to issue an RMA for me. I just had to explain my situation with them about Samsung USA/UK unwillingly to repair the phone.

I just hope Handtec covers it. I've never dealt with their warranty before and I've been trying to find if anyone had any experiences with it. I remember people saying they'd cover it for 24 months which is why I went with them in the first place.

Good luck, they probably updated the warranty thing after the March sale because of the confusion with the warranty status.

Absolutely. I replaced the batter with the official Samsung extended 200mAh and it turned on, funny thing is though that the same thing is happening again...it still turns on but it's getting super hot and draining almost instantly. The phone shows that it's plugged into power but it says under the battery option that the device is not charging, weird. This is what it shows my battery stats as:

The first death drop in charge is when this all started, the second one is what's happening now. It seems to be charging okay now via PC USB which doesn't make sense to me, cause I tried my wall charger and my car charger earlier and it got super hot and said it wasn't charging.
My phone is getting hot right around the area of the "Texas Instruments TWL6030 Fully Integrated Power Management with Switch Mode Charger" as seen here:

I see. So your phone is draining the battery and not charging at all. Have you considered doing a factory reset? Maybe invest in a battery charger for the time being until the phone starts to charge the phone properly.
Oh, just a follow up on my situation. My NAND is still broken beyond repair. Tried ODIN, OMAP flash, different USB cables, drivers and nothing will write to the NAND. I contacted Handtec and they told me to RMA it to them. So I'm gonna be doing that some time this week. They want original box and everything that came with the phone so I'm trying to gather all of that before I ship it to them. Hopefully the turn around will be quick cause this Galaxy S (which also had a NAND hardware failure and repaired once by Samsung then failed again) is getting old quick.

[Q] N7100 Suddenly Won't Charge - Ideas?

Hi all, I'm pretty lost here. My Note II (N7100) suddenly won't charge. Earlier today it charged just fine. I've only ever run stock with root on it. It's not the charger, it's not the cable. I've tried many of both, all of which worked before, none of which work now. I flashed back to stock recovery and did a factory reset, and the problem persists.
When I plug it into a charger while off, briefly a gray battery screen with what looks like a stationary 'wait spinner' will pop up and then the screen will turn back off again. I know the USB port is not totally FUBARed, because I can flash it with heimdall in Linux. It shows up in lsusb when in the bootloader, but not otherwise. The port is pretty much spotless, especially compared with that on my GNex, which still works fine.
I've tried leaving the battery out for an hour, holding the power button, etc. It almost seems like a problem that could be solved by discharging some capacitors, but battery pulls always solved those on my Galaxy Nexus.
Any thoughts on other things I can try?
I can't even figure out how to contact Samsung support in case this is somehow a warranty/hardware issue. At least on their US site the N7100 isn't even an option in the pulldowns they want me to go through.
After some calls to Samsung USA and Canada, I gave up. Apparently the phone is from the UAE, for which Samsung USA has no phone number, and their repair centers won't touch it if it's international. This is really stupid and I plan to write to Samsung about it. It had only been three weeks since I ordered it, so I am returning it to the Amazon seller for a refund. I'll let them deal with their supplier in UAE I guess. I hate to do that, but it seems to be a hardware problem and I have no other recourse at this point.
I cant really help here but i wanted to let you know i had the same problem with a white note 2 from Carphone Warehouse in the UK, just stopped charging after owning the phone for 2 days (i had also only rooted and running stock rom).
Carphone warehouse replaced the handset for me and havent had a problem with the new one so far but its made me take extra care when plugging or unplugging the usb cable ( i use Airdroid for file transfers now). I guess there must be a defect with a limited few usb ports on the note 2.
I thought it might be a 3rd party usb cable to blame (i use a blackberry usb cable at work but ive stopped that now and only use the official Samsung cable).
Sorry i cant help just wanted to share my experiences, hope you get it sorted, good luck!
Thanks for chiming in Steve, good to know I'm not the only one. I saw another post on here like that too, maybe it was yours? There was no discussion. The strange thing is ODIN worked just fine. Maybe a loose connection only on one/both of the power pins?
Nah it wasn't me mate, I had just put it down to me being heavy handed and thought nothing more of it till I saw your post.
I've seen a post in the Jellybam thread today about the charging being down to software but I don't know how true this is as i've yet to check the facts.
Did you manage to get it replaced? I remember it was the worst feeling in the world when the realization hit that my phone wouldn't charge.

Yeah I just invoked the Amazon.com return policy, sent it back for a refund, and ordered another one. It was supposed to arrive today, but apparently UPS had some kind of mechanical issue and now it's delayed until tomorrow. I just need it to get here before my next month's Verizon plan bills so I can cancel before paying another month.
Sorry to drag up an old thread but this has just happened to me, EXACTLY the same as OP.
I've reset it, wiped everything, re-flashed latest stock firmware. Tried 3 different cables and two different chargers.
Pretty sure the battery is good because if I take it out of the phone and charge it on the dock, it works fine. If I then put the battery back into the phone, the phones works in every way except it wont charge
I have most of my digital life on this thing, I am so screwed without it. Look like its a warranty repair job then? Ive had the phone about 3 months from Phones 4U :crying:

Happened to mine to T-mobile version. Never dropped it, never got it wet, only 1.5 months old.
WTF? Seriously?
Behavior:
Charges sometimes.
Charge sometimes stops at 70% or less.
Screen sensitivity screws up sometimes.
Data constantly being transmitted whether WiFi or cell network.
Never dropped.
Never wet.
Never harshly impacted.
Never rooted.
Tried factory reset.
Tried pulling battery.
Tried different chargers and cables.
Wondering if the trident aegis case put too much pressure on the charger cable by pushing it sideways with the flap.
Any ideas?
Hardware problem.

Check in the box, and if you have an EROS Group sticker on it that means it's covered under warranty here in Dubai, UAE as they are the main distributor here for Samsung products.

This happened to me yesterday after spilling tea on it. I took the device apart as per this video, checked the connectors and reassembled it. Voila, the charger is working again. Obviously I take no responsibility etc etc.
My Samsung Galaxy Note 2 wont charge
I have also had this problem where my galaxy note 2 wont charge. I have tried all the chargers i have used successfully in the past and none of them will charge it now. I had the problem some weeks ago and now it has happened again. I only purchased the phone in January 2013. It is very frustrating. I have never dropped my phone or damaged it in any way what so ever. I have no idea what the problem could be but i will be taking it back to Telstra as i need it sorted out.
Same problem here - is this a generic problem with the Note 2??
I always put my phone on charge overnight , woke up yesterday and it hadn't charged. Swapped batteries - no problem - then put original battery back in, hey presto, charging!
But since then both batteries have run out and I couldn't get either to take any charge. Got it plugged in now and just like other people I've got a static charging ring showing, And no power.
Bought an external charger to try and get round this, but has anyone come up with a proper solution??

tab gets flickering screen and reboots

I dropped by tablet battery down once and now every so often the screen flickers with vertical lines and this is followed by loss of network and the thing reboots.
I've read this to be a battery problem.
Warranty is still active but I've rooted it and my Knox counter has gone up.
What do you think XDA? Just get a replacement battery?

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.
i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

Well ive opened it up and tightened everything i can see and it seems to work ok for a while, when the charge gets to around 20-30%, the tablet flickers, all mobile connections are lost and 75% of the time, reboots.
So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...
You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

I am facing exactly same issue what you have described and am in same situation, have tripped Knox on my Tab S 8.4.
I can see that you have been able to suppress the behavior by putting it to Power Saving mode. Have you experienced flicker and reboot since then? I am planning to take it to Samsung store not sure if they will honor warranty, did you tried that?

So i went ahead and got a new battery. Now this was worse kinda. At random moments, like unlocking the screen, or replying to a message, or maybe just a high cpu load event, the tablet just turns off and is unable to be powered back on without first connecting it to a power supply like a wall charger or a power bank.
The time and date will be reset once its back on and ill have to wait a few minutes before the auto network time setting kicks in before i can use something like whatsapp.
Anyone got any clue what might be causing this problem? Thanks in advance, helpful xdarians.

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again
i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!
hmm. i'll have to give it a try. you think this may be something to do with condensation?
Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.
Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!
My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!
I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.

Strange Charging Issues *Please help!*

I'm at a loss as to what's going on. A few months ago I was changing up my ROMs and went to charge my phone and left the room. When I came back I was smelling that dreaded burning circuit board type of smell. Now none of my stock USB cords work with my stock charger. In fact I have 50 or so USB's and the only one that will still work is an old one from my Samsung device.
Just today I got a quick charge 2.0 and plugged it in and to my surprise it worked! Then about 30 minutes later noticed it was not charging. Hold the phone up to my nose and sure enough I smell a slight burning smell again. Is my device no longer going to be able to charge normally? I can't think of anything else to do. Could it be kernel related? Any help or troubleshooting ideas would be wonderful. Thank you so much guys!
Seems like that is a problem with your phone components not with software.Tell me about your battery life.If you connect your phone to a PC did your phone charge?Did you tried changing your rom with the original one?

Thanks for the reply. PC only would work if the cord being used was one of the 1 or 2 that actually work. I did have a little increased battery drain that seems to be decreasing my battery about 30% or so faster than before. I was going to investigate further, but it wasnt at an alarming rate as of yet. I honestly chalked that up to the ROM. I have Multiboot installed and CM6 is the same...100% hardware issue at this point...just not sure if the root of it started from the kernel or not.
I do have an update though...so it seems the part that burned last night was the final straw and now even the 1 charger that worked won't do anything...seems like I'm dead. Took it into Sprint (I have insurance) and they are going to replace it. Sadly looks like it won't be here until Tuesday. I tweeted Sprint about the issue and they'll be calling me shortly. If my insurance/warranty covers my issue and it's believed to be a defective phone I do not understand why I should be without a phone for 6 days. At the very least give me a loaner...but even that doesn't seem to be the best solution for an issue such as this. Good news is my phone won't take a charge so there's no need for me to try and make sure they can't tell I'm rooted.
Sprint used to be really good about customer service w/ having phones overnighted to your house or in store exchange. Those are distant memories now though.
Ig that helps you.My phone is in the repair store too and a guy from HTC told me that the repair for my phone will last for 40 working days ).So...6 days it's a WONDERFUL period.I am not so lucky as you.
P.S.They just have to change my camera module.

Replacement battery

Anyone replace their battery yet? I bought my note 10 refurbed and never felt it had the power it should. Will last 3ish hours with light gaming and web surf. I've seen some replacements on amazon, just wanted to get some input.

I bought one from zwxj on Amazon a couple of weeks ago. 20 minute install. Very easy. There a a few youtube videos you can search for that show the entire process.
I'm getting about 8 hours or more of screen on time now.

I bought one from new power 99, was getting 10% loss for every hour for the first few months but then it started to go alot faster. They have a 1 year garantee on there batteries so i just wrote them 2 days ago and explained what was happening and they sent me a replacement the day they got my email. It was a little more expensive but definitely worth it. They also told me to just keep the first battery. So i would definitely recommend them . They didn't argue or tell me I'm doing something wrong when I sent the email , they just shipped a new battery out. It comes with all the tools to take tablet apart and was very easy to do.
So my battery is fine except when playing games. It's drops insanely fast. I have a refurbished model and am thinking a new battery should do it. Anyone have that issue and a new battery take care of it?

My battery life is getting much worse, and the tablet is now 2 years old. Looks like time for a new battery here too...
Don't know if I need one yet. I know I leave it on the charger quite often and it seems to drain much faster under load than my refurbished nexus 7 2013, but standby time is much, much longer than my nexus 7. Disassembly also seems like a pain. I don't like that you have to pry on the screen

Like the rest of you, I'm experiencing severe, and rapid drain from my battery. I just bought a brand new OEM battery for my tablet. Hasn't come yet, and I will let you know about any difficulties. YouTube videos make it look like a fairly easy job, and it doesn't look like there's much pressure on the screen while you do it. By the way, just for giggles I decided to check how difficult it would be to access the battery. Take it from me-DO NOT TRY TO PRY THE SCREEN LOOSE! You might lose the power and volume switch caps. Only remove the screen if you need to replace it.
Rather, pull the S Pen from it's socket, and gently pry the back cover loose. From there, follow the directions on YouTube carefully. When you are done, gently reseat the rear cover, and make sure that it's properly seated. You'd never believe that piece of chrome coloured plastic was so important. Sheer Genius!
Well, hope that helps.

Changed my battery about a week ago. Wasn't very hard and the results have been amazing. So happy.

Get the one used in the most wellknown tutorial vid, from Newpower99. I wonder whether they ship overseas.
Any way to check to see how much power or life your battery has left? Just bought a used one and seems normal.

i got it from zwxj on Amazon. it was cheap. it was actually very easy to install. there was a small issue though. the cord that connects the battery is a little to long. and the plastic piece at the top isnt exactly correct. i was able to get it in though with minimal effort. they battery lasts forever. the only issue i have and it is a pita is it will randomly shut off when playing a game. doesnt happen all the time and there is no rhyme or reason to when it happens. i need to plug it into the wall and then it will restart with the same battery it shut off from. i could read things all day down to zero and it would never happen. wither way for the 15 bucks or so i spent on the battery it makes the tablet usable again and i love it.

I've bought one from AliExpress with the same issue in the little plastic piece on top so I guess it's from the same manufacturer. Mine constantly turns off. Even updating apps. It seems to be an issue with these batteries.
Also, I feel like it doesn't show the correct percentage. Is there something I should do after replacing the battery for it to show the correct percentage?
One last question and this goes to everyone. Using Ampere, could you please check and tell me whats the average drain in mA?
Thanks!
I use Battery Monitor Widget, included in the 3C Android Toolkit, and samplin battery data in sync with Android to save power. So Standby values should be too high to be representative, 0,05 to 0,2A. Idling with screen on, around 0,6A. Max Load should be over 2A or ten watts. These values should be calculated from the battery voltage instead of the Usb voltage. Attached to a power supply, the Note never seems to drain the battery, so there must be a ten watt power limit, it will simply no longer charge under full load.
Using improper plugs doesn't sound like a good idea, the contacts could get so hot, that the plastic of the plug und socket or the back cover could melt and the contacts could de-solder themselves from the main pcb.
Just ordered a OEM Samsung battery today. Will post when I getvand get it installed. Battery is totally flat on my device.

I had the exact same thing happening with mine after replacing the battery. Check your CPU clocking. If you're on a CM ROM it's probably overclocked & set to 1900MHz. If you set the governor to 1300MHz (which is the factory clocking speed, I think) it should quit shutting down like that. That's what I did and I haven't had it happen even once since. I think the CPU is just overclocked a bit much for the aftermarket battery to handle. Your tablet will run a bit cooler this way too.

I just replaced my battery as the tablet had become unusable. I found the same issue. Only happened once, I also found that I could only charge the device while off, I reseated the charging flex which seemed to correct the unable to charge while on. Now that I think about it, I was on a TW 4.4 rom rooted when it happened, I'll report back with findings.
I contacted Samsung support and they referred me to a distributor of official OEM Samsung parts. Ordered a battery last week. Unfortunately, delivery is in the 2 to 3 week timeframe, as it's coming from overseas. I will let you all know how replacement of it goes.

If you want or need directions for replacing the battery, when I did mine about a month ago I posted a step by step guide for what to do along with pictures (just ignore the part about removing the charging port if your only doing the battery). Here's a link to it http://forum.xda-developers.com/showpost.php?p=66124495&postcount=13
