Hello guys,
I'm facing a very troublesome problem,
Whenever I plug in my GT-N71000 to my charger or the computer, the phone shows that error "Charging paused. Battery temperature too low", or if the phone is off it shows the yellow exclamation point with a thermometer.
I know that must be a really common thread here at XDA-Dev but I have searched the entire internet to find out a solution for this. What have I already done:
When it appeared for the first time I could take the battery off and put it again and sometimes it would charge whenever the phone wanted (I didn't know before that Note II had personality). I downloaded apps that monitor the battery temperature and it showed -20°C. Really freaky. Then I moved to another country and sometimes it worked. I opened it up cleaned and I could charge for some time, then it came back. I went to the Samsung Service and replaced the charging mechanism and the phone worked fine until last friday after a drunken night when this problem showed again!
It happens even with other batteries, so battery problem is ruled out. I opened the phone again and checked the PCB it looks fine, doesn't have any damage of water or any corrupt paths.
I even rooted, deleted battery stats.bin . Reflashed to stock and it's no use. What makes me believe it is some hardware problem with the thermistor that reads the battery temperature, since it was stuck in -20, -19.
Is there a way to reprogram the kernel or whatever coding is responsible for this reading to fool the phone that the battery temperature is at normal levels, so this way I could charge and use my phone normally? Has anyone any solution that I haven't tried? I want to try everything before going to Samsung again because I'm really sure they will say they have to change the whole PCB.
Thank you very much
Well, just a quick update.
I haven't found a solution yet. I bought an external charger so I can at least use my phone but haven't arrived yet. I searched and searched and the only place that I found about anyone having some sort of solution is on this thread http://forum.xda-developers.com/showthread.php?p=47008088 .
But i have no idea how to patch that kind of code in my phone, nor I know if it is on the Kernel.
Anyone might wanna help? Thanks!

My defy is barely 2 months old, i am running CM7.1 since it was released and its quite smooth with no problems till now.
But recently i went to a remote place (i made another post somewhere) and switched SIM cards, i switched back SIM again now. Since then, my defy randomly dies sometimes while holding it and most times while in my pocket. My battery percent looks fine (i wiped it just in case).
This happened to me several times, i suspected the battery was loose, so at the beginning i reinserted my battery 2-3 times and it would start again. But now even after reinserting the battery it refuses to turn on, i usually need to connect it to a charger (or USB) and after the LED light turns on, i can switch it back on, disconnect it and use it again.. until it dies again randomly.
I tried inserting a piece of paper as padding to prevent the battery from moving, but didnt help much. When i shake it a bit, it dies too, so it might be a loose battery or some hardware problem, but the reason im baffled is why i cant turn it on again without connecting it to a charger, and also why it dies randomly when i leave it alone and didnt even touch it. Also, i never dropped it even once or mishandle it at all to make the battery be loose, when i insert tha battery, it still snaps/click into place just like when it was new.
ANy help suggestions will be appreciated. Sorry for the long post, just wanted to provide a detailed account.
I found an almost similar problem but no answer here http://forum.xda-developers.com/showthread.php?t=1109429
Firstly, check if your setVsel settings is all ok and not too low down specially the voltages settings. If you're not using SetVsel, then check your 2nd-ini in system - overclock settings, see if it enable and check those individual settings which might be too low that caused the phone under power/voltage and triggered self shut down.
Another option to narrow down your issue is trying another battery. Buy or borrow from a friend. If the case of random shut down still occur, then it might be hardware issue in your Defy mainboard. BUT.. I would flash it to another rom to make 100% sure before sending it back to the shop.
Thanks a lot for the reply, im not sure if its an overclock or vsel issue because it even dies sometime while booting up if i move it around, so im guessing battery or mainboard issue?? Ill have to check with another battery first then... hoping its not a mainboard issue coz the nearest service centre is miles away from where i live
Hi, need some technical advise on this issue. Apparently, I have a set of Galaxy Grand from China Unicom. The thing is that it is on stock. I gets heated up super hot whereby I can feel the blistering heat and when plugged in to charger, it just discharges and not charging. The phone is hot with or without charger plugged in. It has never went to water contact before. I am puzzled, I can't flash it to any other firmware as I've read the I9082_CU phones are sort of like firmware locked. The phone will keep on draining battery until it kills itself off. The only way to charge it back is for me to charge the battery with external charger.
If anyone has any insight of this issue, or have a schematic diagram for any jumpers to the mainboard, please share thanks. I suspect something is drawing power or a blown capacitor or resistor that is causing this. Another thing is that whenever I try to activate the wifi and bluetooth , it just says " Turning Wifi On" or "Turning Bluetooth On" it stays for a couple and reverts back to off position. However I noticed even in the off position, the WIFI or Bluetooth icon is dimly lit.
I thank everyone for any insight on this.
Regards
phone is getting slower
am also facing the same problem... & now a days am not able to open the google play store, when i open it, my phone hangs & after some times error message wil popup on my screen like "unfortunately google play store stopped", please help me with a solution for this.....
I never knew Grand has a carrier-locked variant... Given its target market in developing countries, not US.
Your best bet is to complain to your carrier and claim your warranty, because it seems like they have done lousy modifications to the phone...
The thing is these phone was purchased from China, didn't know it too that they locked the firmware but after reading from a couple of guys here, it seems it's locked. Battery is draining like crazy , 1% every 20-30 secs. I think it could be firmware but maybe it could be hardware as well
This could be a faulty app/firmware---which can be detected by some system monitoring apps on Play Store---a bad kernel or some faulty hardware...
There's no solution for faulty hardware... just dump it if you can't bring it to a service center
Can you root and install a custom ROM on a locked firmware? (sorry I've never used a locked phone before) This could be a fix if it's a faulty app/firmware/kernel.
Hi all,
I have been running my Z1 Compact on 4.4.4 for the longest time, mainly due to sound issues after updating to Lollipop.
Recently, the battery has been dropping randomly from 60 odd percent to 3 or 4 and then shutting down all within a few seconds. The last time it did this, I tried charging it when I got home but the charging light would not stay on, thus it was not charging. All typical signs of battery failure due to age.
Having already replaced the battery successfully on my Z1, I bought a replacement original Sony battery and replaced it. The problem persisted. On first boot, the phone got to the blue waves then black screen, and power off. Charging screen just showed the battery at about 40%.
I risked it and flashed the latest software with Flashtool, having done a complete wipe. The result of this proved no better, but I did get a different message on the charging screen, a message saying the phone had shut down due to overheating. Picture is attached.
The phone is in no way overheating and I've even booted it while sat on a shelf in the fridge to help dissipate any heat generated but with no luck.
So, the old battery maybe did overheat and caused the phone to shut down, I'll accept that as a probability. It may have even damaged something, but I don't think that's likely.
After changing the battery, I would have expected the problem to resolve itself, but it seems like some kind of hardware 'flag' has been raised that is now not allowing the phone to boot in case it overheats again.
Does anyone know of any way to resolve this, reset the 'flag' per se, other than going to Sony? The phone is definitely out of warranty due to its age, never mind me taking the back off lol
It is a shame because it has been a great phone over the years, and I would like to fix it if possible, even if to give it to one of the grandkids. I have my Z3 still (which I won't part with for anything) and I have an XZ too and both are great phones. I would just like to save the XZ1c if I can.
The phone is not, and has never been modified in any way, no rooting, no bootloader unlocking. Only stock roms have ever been flashed, and then only once or twice, to put it back on 4.4.4.
I have tried reflashing just the kernel, or just the system too, to no avail.
In desperation I even left it in the fridge for a few hours in case the temperature sensor was on the fritz, but that did nothing at all.
I just feel like there's nothing actually wrong with the phone, apart from this trigger that won't reset.
Any help greatly appreciated of course.
Thanks,
Mick
Maybe theres lot of consideration:
1. Rom Bugs
2. The Kernel not supported well
3. Battery Issues (But you already change it right)
There are two temperature sensors afaikin our phone. One in the SOC and another one in the battery (hence three pins).
The battery is probably the one giving the high temp report. Try yet another battery.
A bad battery normally heats up very fast inside and the battery temp sensor stops the battery from charging and/or working to protect the phone and the battery.
I changed my battery before when it had symptoms like yours 100-90-0 drop and after replacing with a battery from eBay it was OK. I gave it a full charge then complete discharge and then complete charge to full cycle the battery once and let the phone Guage its full capacity. one year later now my battery is acting funny again (not charging past 30%) and getting so hot when charging it triggers overheat control service in Android.
Any luck?
Apologies for the necro. But did you ever fix this issue, having the same problem

No, I never did figure it out. I've been loathe to spend more money on another battery when I've got other much newer phones. I really have no idea why it would not reset once the battery was replaced, maybe it's the replacement battery.
Have you tried changing the battery?
I've tried flashing different stock roms, Kit Kat, Lollipop, and it doesn't help.
Short of going to Sony, I'm not sure what else to do.
Greetings, all.
I am in dire need of help. My plight is as follows:
I am soon going off to college and have a Samsung Galaxy Tab Pro 8.4, SM-T320. I am fairly technical, and have fixed computer parts prior. However, I had weak charging, and I decided to pop the back off to get the serial number of the current battery. It was a T4800E, in case that is relevant. I went to eBay, purchased the battery, and just installed it about half an hour ago. I expected the battery to be low and/or dead, so I plugged it in. I immediately have an issue which I am not sure is severe or harmful to my device.
Currently, the tablet is sitting next to me on a stand, plugged in, and the oddest thing on the screen: the battery charging animation when powered off (the battery in the center of the screen) is starting (i.e. showing the "loading circle" in the battery), but is not actually showing the charging bar animation, powering off, and repeating. I will leave it overnight, replying in the morning with an update if you wish to know, and if the problem ceases, I will simply delete this thread.
If this is still up the day after OP, it is likely still going on (check below for an update from me), but I just want to get an answer as soon as possible.
To answer some possibly-relevant questions:
Yes, I still possess the original battery, and can replace if you feel is a good idea.
Unfortunately, I am completely opposed to cracking or anything of that sort, as I wish to avoid the possibility of bricking and/or permanent damage.
Thank you in advance for any help,

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.
