Hardware issue with battery, crashing, rebooting, powering off - Galaxy Tab S Q&A, Help & Troubleshooting

I just bought a used SM-T800. I didn't see any immediate issues but I've noticed it has been intermittently powering off or rebooting on it's own. These aren't graceful shutdowns, it powers off immediately, either when I'm using it or I'm not touching it. It can even happen while the battery is supposedly full and the charger is plugged in. This can happen many times in a row, a lot of times during the bootup process. If I leave the cable unplugged I've noticed if it finishes booting the battery can sometimes claim to be almost dead at like 3% when I thought it was 100% full.
I've done a bit of searching and saw a reference to an issue with a cracked interface to the battery. Is there a known issue with this device regarding this? Any detailed links on this? My alternative was to buy and replace the battery. Anyone else having the same issue?

Yes, I've seen that happen with the video glitching but it doesn't happen all the time.
Currently my device won't boot up anymore. Even with the device plugged in, the surge of power it needs to boot up isn't available from the battery.

As was mine a couple weeks ago, i tried everything...rooting flashing re partitioning, you name it, i did it. NOTHING WORKED!!
Until 2 days ago i opened up the back and noticed that the piece where the battery wire connects to the motherboard was loose i simply placed some foil above it and closed it up again( the foil put pressure on the connection which allowed it to carry power across). And now everything works fine, while its not a permanent solution(ill take it to samsung sometime later this month) it does work and now my tab is fully functional. While i dont know your situation this worked for me so maybe it will work for you...Let me know how it goes!!!!!

My Samsung Galaxy Nexus won't turn on

First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.
Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!
Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:
Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth
Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!
That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.

Thanks!

Hey Balums,
My GNex didn't turn on this morning and I was really confused as to why it would do such a thing, until I saw your post. Thanks a lot for posting your uncle's remedy!

Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools
Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?
Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!
Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?
I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.
Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

galaxy nexus reboot
my galaxy nexus is about 1 year old now and this is the first time that i've encountered a problem with it. It suddenly restarted, and will take about 5-7minutes before it opens, it will be open up to the "X" logo and when it reaches the normal screen it will restart again. I don't know whats wrong with it. please help/

You saved my Galaxy Nexus
Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?

Not charging, screen flickering

I bought a note 10.1 2014 Ed a couple of weeks ago on eBay. Not refurb and sealed in the box.
Devastated to find tonight, after completely discharged and shut down, that it seemed not to charge at all.
It becomes stuck on either the battery symbol, where nothing happens, arrow doesn't spin and no animation, or goes to the device model name. All the while the brightness flickers.
Have tried various chargers, I've taken all the cards out but nothing is working
I think it may be a loose connection with the battery (but open to other theories).
If anyone has had this problem, how have you fixed it? Is it worth disassembling and trying to fix it myself (as I'm sure you can tell I don't have a lot of knowledge about this)? Being an eBay purchase is it still under warranty with Samsung? How much would a fix be if it was a loose battery?
Thanks in advance

As far as I am aware items from ebay are not covered under warrenty.
Even with the screen off and nothing happening, leave it on charge for few hours then unplug and try to put it on.
Also have a look into the charger port of the tablet at the bottom to make sure nothing looks bent or out of the ordinary.

samsung sm-p605 dead not starting
havig the same error mentioned above.. got the device new from amazon, shipped to chile where i live.. recieved it and tried switching on and didnt switch on.. tried connecting wall charger for couple of hours no progress not even battery symbol coming up.. tried usb to laptop battery image comes up with no animation.. and screen flickers... boots in odin mode... when tried booting in recovery mode stucks in screen where the model name appears...
plz help since i have 0 hrs of usage completely new.. chile samsung doesn't accept becos its purchased in usa.. any email of samsung will also help
shame i always liked samsung over apple.. and bought a product with no support.. apple atleast accepts product bought anywhere in the world and even replaced battery for my frnds iphone 5s when in warranty...
I have not had this issue with my Note, but my Nook did the same thing once. I disconnected the battery for a few minutes and everything reset. No idea if this will help, or if you are adventurous enough to try it.
Here are some pictures of the Note tear down. http://forum.xda-developers.com/showthread.php?p=49595697
samsung sm-p605 dead not starting, screen flickers
i am going to try removing the battery as u said.. lets see..
anyother ideas plz let me know..
but shld i do this quite often?? is this an known error of note???.. do we have this problem when complety drained????
samsung sm-p605 dead not starting, screen flickers
no luck.. i removed the battery from the board, then plugged in back after couple of minutes..
still in same state..
the screen flickers a lot.. is that normal when the note is completely drained..???
It is very bad for the battery to go completely down. I don't let it happen on my devices, so I cannot say if the flicker is normal.
My experience with the Nook was actually a friend's device. He had let it run down, and it was not charging. He left it on the charger for a few days, and it was still not showing a charge. He gave it to me to check out. I disconnected and reconnected the battery. It was probably half an hour or so, because I was interrupted. When I reconnected the battery, the Nook popped on and reported a full battery. Apparently it was charging but not registering anything, and the disconnect allowed things to reset.
If you do not any other ideas, I would suggest leaving on the charger overnight (or longer) and trying the disconnect again. Maybe leave it disconnected longer too.

I have the same exact issue right now! But mine is a refurbished unit. I tried the battery unplug, tried leaving it charging overnight, letting it discharge, flashing new roms, new kernels, etc. Nothing. THe only thing that did work a little bit was changing the kernel. Other than that, even flashing stock ODIN roms wasn't working.
When you charge yours, does it charge up to 75% but won't go any further? And does it take an extremely long time to get there? Because mine does. Reading about other devices that have the same issue, it seems to be the battery. But the other devices were phones. This is a tablet. The battery costs $65 :/

I know this is a very late reply and you have probably solved your problem by now, but for future readers with this problem:
I currently have the exact same problem, and just found out what it was. Either my charging cable (official Samsung cable) is faulty. I plugged it into another microUSB cable, and it is now charging again. No more battery symbol that doesn't have the spinning animation or flickering, and now it turns on.

Thanks for this information. Exactly this was the issue. Great!
Charging works and screen stops flickering with Samsung charger if you let it charge in Recovery mode. Mine is still charging as of now, so I don't have any news further yet, but it went from 0% -> 3% after around 30min.
Other than that, I only managed to get charging working with a Motorola's turbo charger.

Charging issue with Tab Pro 8.4 and newest update!

I just developed a charging issue where I have it plugged in and it hasn't advanced in %. It's stuck at around 65%. Official charger/usb cord and tried different outlets.
This never happened on the first firmware build, but only after the second update the last month.
Anyone else experience this?
I've encountered it both in stock and cm11. Run the batterybdown to 10 % and fully charge. Should report properly then.
Sent from my SM-T320 using XDA Premium HD app
I'm running the 8.4 original firmware without issue since I bought it several months ago. This week it charges up to a point then stops. Restarting does not help. Different chargers, etc. Arggh!!
This worked for me: (Press and hold: Volume Up + Home + Power (in that order)). Keep holding an unit will reboot. It's not abrasive like a factory reset (like I was considering doing).
Now for the first time in a week, i'm over 50% and its still charging like it should.
Someone else did all the hard lifting to find the solution. I just found the tread over on android central. http://forums.androidcentral.com/sa...y-wont-charge-without-reboot.html#post3723135
Cheers.
I haven't upgraded, but I did encounter the same problem earlier this week. It was stuck at 91% even though I left it charging all night. After restarting and plugging it into my laptop for a while, it seemed to work fine again. Now and then it'll just do strange things like this. xD
I'm having same problem, stucks at about 57% 69%. can't find a solution yet. In my case it is happening after software upgrade. does anyone have a solution that helps ? restarting does not seam to be a solution.

Pretty much a known issue on all software builds (maybe a hardware issue?). There is a long thread about this issue in this section. The only consistent solution seems to be to open up the tablet, and disconnect/reconnect the battery. A bit extreme for my taste, so I've just left it alone. Sometimes mine will get stuck at various percentages (for a few charge cycles), sometimes it will charge up to full. Reboots sometimes help, but not always.
II found this and it helped some; including myself... Hope it works for you...

Pro T320
Went from a machine that could discharge completely in a few hours doing general surfing and messing around. (Not gaming or video).Taking all night to charge to 70% and constant reboots to get to 100%.
Took the back off and disconnected the battery as per advice on this thread.
At 97% it now gave me nearly 6 hours video streaming down to 17%. Only took around two hours then to fully charge.
I was a little worried about doing it but it is well worth it.
Tip I found two thinnish guitar picks worked really well to ease the back off.
I never had this problem or as bad as some users but I have notices a few things to keep an eye out for
When you plug your tab into the charger do this
Go to settings - Battery and make sure it says Charging (AC) , on a few very rare occasions I found that sometimes plugging it in it wouldn't switch over to charging (it would still say discharging even though it was pulling current from the charger) and required a reboot I suspect this could mess up battery stats pretty bad, another way to tell is when you plug it in, shut the screen off for a second or two, then press the home button or power button and make sure it says Charging xx% on the unlock screen.
another way to charge is just power it off (power button for 5 seconds, select power off on the popop menu) plug it in and you will see a big battery charging animation, you can regularly check updates by pressing the home key or power key...
Oh and toggle off WIFI (found out wifi can pull an additional 100mA when tablet is in standby), bluetooth(not necessary unless you were using it), and GPS before charging.

Replaced screen and battery, now in (another) bootloop!

Recently I posted about a problem others had as well - when under 50% ish battery, my HTC 10 would randomly reboot, and that would loop until it was plugged in.
Once plugged in and fully rebooted, the battery % reading would vary from where it was before to 1%. Also, certain apps' data or cache would be deleted. I would open, Macrodroid, for example, and it acts like it's the first time being opened after installation.
This has been exhausting, having to constantly be charging, staying above 60% - and even then it still happening. After it does, the apps whose data was cleared varied, and I wouldn't always know until I opened each.
So after this I dropped it and cracked the screen. I have fixed all of my HTCs before with various problems - M8, M7, DNA, Incredible, Max - so I decided to put in a new battery to hopefully fix the bootloop problem.
After watching a few disassembly videos, it seemed best to replace the screen when I opened it for the battery. So I ordered a screen, and waited more, constantly charging, restoring data to apps like Macrodroid and initializing apps all over again.
I finally have the new battery and screen. I have a few hours. I get out all my tools.
A few hours later, I have put it back together. It's like Medusa inside this thing! I was really being risky doing this last night, because I have a ton of work to do today, yet here I am typing this on my backup nexus 5x - so slow!
So the result? Success for the screen replacement, and the battery as well. But, now, it is bootlooping still! I plug it in, and two things:
Plugging it in does not stop the bootloop.
The charging LED does not light up.
So I am hoping someone may have some insight as to what I may not have connected properly. I can post pictures later, I'm not home right now.
I looked and looked and looked and cannot find where I went wrong. I am going to take it apart and put it back together if I can't find the error. Any ideas? Any other places I should post this?
I guess when I get home, assuming it has completely drained itself, I can plug it in, and see if it gets a charge, and if the LED illuminates. I am thinking: charging port is not properly connected back + the new battery did not fix the bootloop / battery issue.
Thoughts?
Bootloops/shutdowns are going to corrupt your data. I would RUU the thing before looking for hardware trouble, which you've likely sorted out by replacing the battery (of course, we're assuming the new battery is good).
BUT before that, is there a memory test in the bootloader or recovery? If so, I would run that very first thing.

Recently I posted about a problem others had as well - when under 50% ish battery, my HTC 10 would randomly reboot, and that would loop until it was plugged in.
Once plugged in and fully rebooted, the battery % reading would vary from where it was before to 1%. Also, certain apps' data or cache would be deleted. I would open, Macrodroid, for example, and it acts like it's the first time being opened after installation.
This has been exhausting, having to constantly be charging, staying above 60% - and even then it still happening. After it does, the apps whose data was cleared varied, and I wouldn't always know until I opened each.
So after this I dropped it and cracked the screen. I have fixed all of my HTCs before with various problems - M8, M7, DNA, Incredible, Max - so I decided to put in a new battery to hopefully fix the bootloop problem.
After watching a few disassembly videos, it seemed best to replace the screen when I opened it for the battery. So I ordered a screen, and waited more, constantly charging, restoring data to apps like Macrodroid and initializing apps all over again.
I finally have the new battery and screen. I have a few hours. I get out all my tools.
A few hours later, I have put it back together. It's like Medusa inside this thing! I was really being risky doing this last night, because I have a ton of work to do today, yet here I am typing this on my backup nexus 5x - so slow!
So the result? Success for the screen replacement, and the battery as well. But, now, it is bootlooping still! I plug it in, and two things:
Plugging it in does not stop the bootloop.
The charging LED does not light up.
So I am hoping someone may have some insight as to what I may not have connected properly. I can post pictures later, I'm not home right now.
I looked and looked and looked and cannot find where I went wrong. I am going to take it apart and put it back together if I can't find the error. Any ideas? Any other places I should post this?

Whatever happened to your phone? I have the exact same problem. Infinite boot loop, no illuminated LED, and no way of getting into recovery or anything else with it bootlooping. It occurred after I made the mistake of trying to restart it at 25%. I have the new battery and screen. i'm going to attempt to open this Pandora's box. Seriously going to have to turn my back on HTC. The 10 is so full of software issue problems regarding the batteries that they never bothered to address.
I did the exact same thing a few days ago and my phone won't charge or boot, but I do think the problem is with the button strip, that's what i think, because i tried turning it on before re assembling it and it did turn on successfully and was charging normally but when i re Assemble it, the phone got this problem, now i think when i turned it on before assembling i pressed the power button with a screw driver because i couldn't press it with my fingers, I think there i messed it up, any advice how to fix the button strip and remove a slip nut would be very much appreciated
I had the exact same issue as you(shutting down at 50%), have you found any solution to it?
edit: I THINK clean flashing oreo firmware then latest RUU then twrp then lineage fixed my issue, charging to full rn will drain it over the next day and report back if its gone for good

My friend is dead:( SM T800 random boots

I don't know what happened, but my true friend is probably deadly ill and she's dying.
My Samsung Galaxy Tab S 10.5 after almost 3.5 years of really hard work, 8h daily of SOT, hard CPU tasks, loading battery two times a day, started to do strange random reboots.
I was installing Blue Filter app, reading big pdf and sending this PDF from Xodo to Voice Aloud reader. Tablet was connected to charger from Moto X Style, which is turbo power charger. I saw first reboot, then other and next. Entered Cwn Twrp, cleaned cache but the problem still existed. Cleaned system, internal storage and tried to flash Iron ROM again. Strange, but tablet couldn't flash Iron ROM 3.2 gauge showed 100%, almost after beginning of installing ROM. I decided to flash 4 elements repair ROM with Odin, but it didn't help. Checked erase NAND, flashed correct pit file.
Strange, but while flashing with Odin, there were no reboots, so downloading mode is working properly. But after install, reboots returned, almost after running system first time.
Maybe it depends on ROM version? I flashed 4 files of 4.4.2 with Odin, while I was on 6.0.1 earlier?
But reboots started on proper ROM.
Also, maybe charger is responsible? Moto X Style 3A charger maybe damaged memory or motherboard of my friend?
Do you think that exchanging the battery may help? My battery when it was loading frequently showed a red cross, it can be that it's damaged, but random reboots never happened to me.
I don't want to buy new device, it's really stupid for me to spend hundreds of dollars every two, there years. I believe that a device should work 5 years or longer. Maybe corporations make devices especially to die after warranty period?
Can you help me to determine what is damaged?
It was my true friend, carrying tons of books with a thin device, reading big pdfs smoothly, making notes tons of paintings, editing photos and taking photos with my Nikon D610 via USB, listening to music with A.r.i.s.e , watching photography tutorials and movies, modern Combat 4 tons of hours, notes, showing portfolio to my clients... Yes I love my small friend, can you help me to rescue it?
You can see the behaviour here
Are the reboots happening even while plugged in or only after unplugging the charging cable?
Also is the percentage reading being sporadic meaning it changes every time it shuts off?
Replacing the battery is fairly cheap and easy on this model.
Here is a guide:

If for some reason it still has the same issue after replacing battery then the battery connector needs to be looked at under microscope. It may have a loose connection to the board meaning it would need to be resoldered.
Dear Benjamen, thanks for your help. Tab reboots even if it's plugged to charger. The percentage is strange, one time it shows 40%, another time beeps and shows low power warning.
Sometimes it works 5 minutes without reboot, some times boots many times continuously.
Do you think it's battery? No EMMC error or some chip damaged on motherboard?
Download mode Odin worked good, also CWRP worked without reboots.
Maybe internal storage is damaged?
What do you think?
If it is battery I can surely exchange it like you wrote.
You can see the behaviour of tablet on YouTube I've posted above.
Have you tried to reinstall Twrp and a custom rom besides Iron Rom and doing a clean flash? Also I was thinking it might be a corrupted sd card try to remove the sd card and reboot see if that works I had a tablet once that was going bonkers cause the sd card was messed up , it might not be it but could always try it. Also make sure your on the proper boot loader for the rom you are trying to flash iron rom thread actually has a link to all the current boot loaders if i remember correctly. I do own this device and run a custom nougat rom no issues, just shooting out some ideas but you are right this is great device and should last a long time.

Sounds like battery connector has loose soldering. Take it to a reputable repair shop that does soldering and tell them to check the battery connector and see if it needs resoldering. That's how I ended up fixing it with the same symptoms that you had.
Edit: Forgot to tell you but I cant play the YouTube video, maybe the embedded video link is invalid so can you send me the youtube link?
Mine has been doing the exact same thing for a couple of days now.
I'm running LineageOS 14.1.
Random reboots both with the charger connected and disconnected, Battery percentage is around 45% most of the time, but jumps to 0% or 100%.
I've already replaced the battery with a "new" one (about 12 months old, according to the label), but to no avail.
Any ideas? I really like this device and would not want to buy a replacement...

My SM-T800 started doing something strange like this yesterday. As I was watching Youtube and reading a news site in split screen mode, the screen suddenly went blank (it didn't shut down, but went blank at once). Before this happened, I saw a warning that my battery charge was below 15%. After powering on the tablet, my charge was 28%. I opened youtube and a web browser again, and the screen went blank within a minute. After powering on, I decided that I will not be using split screen mode again, but the screen eventually went blank. I monitored the CPU temperature and it didn't seem like it was running too warm (50ish C). I will try re-calibrating the battery (if that's even possible) and even replacing one, but if that doesn't help I guess it's time to move on to something new. Sadly, four years after the T800, nobody made a worthy replacement (the leaked Tab S4 specs look good, but they want to charge laptop prices for that).
PS: It's running the stock rooted (later unrooted) MM 6.0.1 from November 2016 with TWRP.
I re-calibrated battery and the tablet seems to be working fine so far.

Okay first of all very big thank you for your replies
my Galaxy Tab S 1 except strange reboots is also overheating when it has some tasks to do measured temperature on CPU cores is getting around 80 degrees Celsius and is going up and then tablet gets restart so I don't know if it is only the problem with battery maybe it's connected with CPU problems or other electrical problems on MotherBoard.
It's worth to mention, that I've charged the tab with charger from Moto X Style, that is Turbo Charger, with 3A, and the Tab S1 can load with 2A only.

Here's the link to movie with Tab behaviour again, can you see it now?

My tablet used to have a damaged main-board that used to overheat. However, the screen did not go blank when that happened. I actually got some kind of message that said that the tablet is overheating. This was fixed after I replaced the mainboard. You can certainly try it, but these things were not cheap when I did it.
Mine also started doing this last month now it wont power on but resets till the battery is dead.
Did you get it fixed?

I'm seeing random shutdowns with no warning popup on heat but the screen area where the motherboard is sure gets hot. I replaced the battery and same result. I looked at the battery connector and looks OK, seems tight but I didn't check with a magnifying glass. Where did you source your motherboard?
Also how has everyone elese resolved this? I see people citing the problem on this old thread but I'm curioius if you found a resolution.
