Xperia play overheating

i rehoused me xperia play and when i tryed to turn it on i just got the blinking red light, so i bought a new battery that worked for 45 mins when it overheated to 47degress then died so i bought a external battery charger and the battery charges but when i put it in it overheats and dies in an hour and when it charges it gets even hotter and dies faster..... does anyone know how to fix this cause i cant afford to buy a new phone anytime soon

Are you using stock firmware or a custom one?

Stock

well the same thing happened to me..
i rehoused my mobile. but when i was closing up the phone, without putting in the back housing, i tried to switch on the phone so i would check if everything was fine or not. But what i did wrong here was that i just inserted the battery in wrong direction. Negative to the positive and vice versa. Nothing happened at that time, and the phone did not turn on. Upon realizing my mistake, i tried to power on my mobile again with the correct battery connections but this time the phone just wont turn on. There was a weird red light that started blinking and the phone just wont turn on.
so i completed the housing process thinking that maybe that was the problem and there was some sort of a sensor or something but that damn thing just wouldnt turn on. even if i put the mobile on charge it wouldnt turn on. so what i did was, i again opened up the back of my phone, deliberately put the battery in wrong position, tried to switch the phone on, and then i put the battery back again in the right direction and as i press the power button, walla, the phone is alive again.
BUT...
its getting HOT. damn HOT. after only being on for about 5 min, the battery got hot to 54C. upon inspection. i found out that the battery is not getting hot, but its the motherboard that is heating up.
i went to the service center, which opened up the board and found an IC that was damaged (caused by my battery mistake).
Found the IC from china. Ordered it, and TODAY it arrived. I will be going back to the service center, for replacement of the IC. If all is OK, i will let you know.
meanwhile, check out the pic of the IC that got damaged on my mobile during the process of rehousing and my stupidity.

hey thanks that helps cause i think i did the same thing with the battery...do u have a link to buy the new Ic?

FOUND a friend in china, and bought the IC from him ..
STATUS :
just now, after connecting the new IC, the phone has started working again. its NOT heating up. Everything is working fine..
EXCEPT
that now my phone shows no signals. In the settings when i search for other networks, i find many other networks also (MEANING THE TRANSMITTER IS WORKING FINE) but the phone just wont connect to my network and wont give me any signals.
I only get "EMERGENCY CALLS ONLY" status.
I am actually getting fed up of this set. Anyways, i hope u get the IC, and your phone works fine. ( I HOPE )

I did the exact same thing and have the same problem, but the difference is when i try the reverse method it still doesnt come on but cud i get a link to where u found the IC

The problem here is the same IC from the picture. Even though I found the replacement IC from China, I still couldn't get my set to start up normally without overheating. If you remove the IC from the board, the phone will start (even without the IC) but you will get no signals
For me, I was unable to get the phone back to its working condition. So I sold the phone as it was.

By inserting the battery in reversed position you probably caused some sort of short-circuit. You probably didn't burn only IC, but many different parts. When the part is damaged and short-circuit exist in it it heats up very very quickly as the current on this part (any many other parts that are connected with it) is very big (this also causes very quick battery drainage). So it means you had probably burnt the mainboard even if the phone switches on, so getting new mainboard is the only sollution to get the phone fully working (as I think you aren't proffessional who can diagnose and repair it. Neither do I ).
I hope this helped somehow.

Hello all I too have an xperia r800i play with the same problem or better the battery under the battery becomes very hot in a few minutes, and drain the battery quickly. Moreover, even when you plug in the charger not charging? only shows the loading icon but then not charged and only the LED flashing red?
And you can not start the phone FASTBOOT? because the LED flashes blue and then turns on a second phone in the normal
how can I do to fix?
thanks

Hey,
i have the same problem.
i tried isolating a pin from battery (the midle one) and i got it to work without heating, i thought it was fixed but then i took the battery back out and overheated again maybe theres something wrong with the pins any alternatives?

i did the same thing my phone is in the fridge now i boosted the battery by usb with bare wires got it started up hoping to get to 50% charge then try a reflash see if that works

[Q] Charging Paused, Battery temperature too low. Already tried everything!

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!

New with the tablet, random shut downs

Hi, i have a Tab S 8.4 and I was using it and suddenly the tablet turns off, I tryed to tun on but nothing, it was totally dead, with 63% of de battery remaining and with no apps installed, just made a factory reset 1h ago, i tried every key combination to turn on but nothing, totally dead, when I get home I connect it to the charger and the charging screen appears so it wasnt bricked, i disconected it because it was al 63% as before, i used it all day and with 24% again, off and the only way to turn on was charging it
Now again, i was trying to play Lara Croft Go and it turns off 3 times with this game, so i uninstalled it, try with Geometry Dash and it was working until I turn off the screen and turn on again and after 3 seconds the tablet was off again...
I dont really care since I can turn on charging, but I dont like this solution because obvious reasons, someone can tell me if it is a firmware bug? My firmware is:
LRX22G.T700XXU1BOF2
I had no warranty so i dont really know what to do, anyone knows about something similar? Maybe its the battery?
Also I cant enter to bootload mode, I tried with all combination of keys during boot and it always turns on normally, what exactly I have to do to enter to bootloader?

Search the forum for battery connector.

thank you, I searched on google by using another keywords and I found nothing wich describes my problem, but thay seem to be the problem as I read.
i really though it was be a software problem, if it is the battery connector how does it "autofix" when I plug in? And how does it always crash on some apps? Maybe when an app uses too much energy it crashes, and when I plug the charger it restarts the circuit? Dont really understand
Anyway if people say its the solution I will try, thank you very much

It's a known issue on your model. There are several posts on the forum regarding this.
There are even tutorials on YouTube how to fix it.

Thank You, any way to repair without buying another battery? People say to fix the connection by closing the female pins but they are tooooo small so there is no way I could make it fit thight, by the way, If I buy an original samsung battery how I know it wont happen again to the new one?
Other peoples tablet reboot, mine just turns off and gets dead until I plug the charger, there is no way to tun on without the charger, Im thinking to buy an external battery such as Xiaomi's one , but im not sure if it will woke up the tablet whe its off, someone have an external battery can test for me if the tablet turns on when you connect the battery?
Thank you e

UCH12

Hello,
Couple of months ago I bought a UCH12 charger and it was working fine with my Z5 Dual Premium.
But since the update to Android 7.0, it stopped working.
I'd plug the charger to the phone and it would vibrate as if it recognized that something was connected but the phone does not show the icon of being in charge and even when I go check the battery usage it says that the phone is not charging.
My phone is not routed. I tried getting help from Sony support, but all of the action tried (reset, long reset, turning on and off, repair, etc...) did not get any results.
Anyone has the same issue ?

have you tried charging ANYTHING else from this charger?
looks like it's dead.

Yep, a Galaxy S7, works like a charm, just hates my cellphone or my cellphone hates it, either way.

try the same chargers while
1. device switched off
2. charging optimization is off
i suspect that charging optimization causing trouble...

1. Same thing
2. I am not sure where to do that, I have check battery optimization but iit only optimize the charge in respect of the apps used. and it did not do anything.
I admit that this is a strange one, has anybody witness the same thing ?
I can always send it for repair (I am still under warranty) but I'd like to use this as last resort (takes some time and forces me to use a crappy phone).

Settings > About Phone > Status

Tried it, no change...
EDIT:
I wonder if this article isn't saying that Google might be messing with Quick Chargers...

Anyone else on this issue ?

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:

Where to buy a replacement battery:

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.
