Overheating, random reboots.. out of warrenty

Hi, I have a HTC desire, its nice but it gets hot latley when playing games like angry birds for a bit when the battery drops to 20% or so, and I plug in in.. it starts doing reboot cycle.. I think it only happens until the phone cools down.
I know the only real fix for this is a new mainboard, but I am not under warrenty..
any suggestions on how to live with it, or work with it.. someone told me a bad sim card or sd card might do this to the phone... I have already put 2.3 on it and factory reset and such...
thanks

How old is it? In the eu the warranty is 2 years.

Wow, good to see im not the only one. I have the same problems, and depending on the rom they get worse or better. im running CM7 now and i have little problems, but when i was running the ICS beta it happend a lot, both on and of the charger and in my pants pocket or out.
If its overheated and i take out the battery i can smell a sort of molten plastic / overheated electronics smell.

for me it was the same - main problem is motherboard.
in the end service center exchanged for me motherboard and now this problem is gone.
but before this exchange i did following:
* decreased max cpu speed to 576-768MHz (via SetCPU)
* in one of old kernels I was able to manipulate with CPU voltage level, so i was decreasing it for all freq. which was used by me.
* charging only via PC usb ports - when it was able to be fully charged and not overheat
but the proper way would be only to bring your device into service center...

I would also suggest decreasing the max speed

might be that sleep mode doesn't work entirely as it should in some roms, not making the CPU frequency drop enough when the screen is off.
And your device might be getting old and wear is starting to show.
If it's actually damaged, replacing parts may be the only solution

This is a known problem for the first devices. The solution is to change the motherboard, of course at the service center.

You need to pick a good firmware I worth Runnymede AIO V 5.0.1 Special Edition-> Base Runnymede 1.22.461.2 Official Sensation sense 3.5 Android 2.3.5 [CM7/r2] [STOCK] [AD2SDX] [A2SD] [BEATS] [RCTWEAKS] [Aroma Touch Installer]
no problems found! the same problems arise Earlier.

How did you void your warranty? Rooting or installing custom does not void hardware warranty. At least I got my pvt1 motherboard replaced even when I had rooted and used superglue to fix some broken plastic under back cover.

Ya, the phone is just out of warrenty, it really is only 1 year in Canada.. no ifs ands or butts...
But the phone only seems to do the reboot loop when I play angry birds when the battery is low and or when I play angry birds when the phone is charging ..
I think it happend once in google street view...
in other words intense apps... that make the phone warm up and then the sensor tells the phone to restart to protect the processor from overheating, but when the phone reboots the thing is still hot so it keeps rebooting.. only solution is to take the phone battery out and let it cool..
I guess this problem could get worse but it doesn't happen with normal web browsing at this point. I might have to live with it until I find someone to replace the mainboard cheaper than HTC wants.. otherwise not worth it.
I guess lowering the CPU max might be great so it doesn't overheat in the 1st place, I will try that.
I don't really understand rom, I have 2.3 gingerbread, is there something else I can change to perhaps get a better radio signal on this puppy ?

I have this problem, although until recently it only when trying to use it as satnav.
I'm glad to hear it's a known problem though.
I contacted my provider and they said perhaps the battery is getting tired and causing it to reboot due to lack of power. I pointed out that it was the other components near the sim & sd card slots that were getting hot, not the battery, so they sent me another one. I did buy another battery too and that has made no difference either. As soon as I rooted the replacement phone it started getting warm too. I'm also pretty sure that the "replacement" was a refurbed one, since the optical joystick doesn't always respond and when typing msgs sometimes the vibe feedback stops working mid-word.
It's very frustrating not being able to use it for navigation any more (although it works happily with My Tracks for recording routes).
However since I've rooted it, I don't think I'd get away with requesting another replacement phone. I've tried installing other rom's that might run cooler, but when I do they always lock at the HTC splashscreen and I have to restore nandroid backup.

Hello,
i'm new to XDA developers. Should i buy this phone? I'm thinking about it these days but i'm not sure if it is worth. Thanks for your answers.

The same Problem on my Phone! While charging i can not use my Phone.
My solution: Don't touch while charging. :-(

I think I have same problem...my Desire in regular use get worm at 35% and at 38% burns my hand...and what is wors,for 15/20 min. regular use(not havy or gaming) temp. rise from 28% to 37% but something confuse me...last night I play 3d games for an 1 hour and at 20 min. I put it on charger and continue to play games and 40 min. later temp. is 40% and stil no reboot but butom side of phone(not battery...front side (buttons and screen) and back side) is so hot that I can burn my hand on it. I put statistic that battery indicator show(time,%,temp.). So is it like that to you guys? Is your phone have that heat thing for 15 min. of regular use?
Its pic of last night 3D gaming and its all statistic of temp./ % / time...

Ok, sounds promising. Can you elaborate on that a little bit please? What settings did you use etc?

Ahhhhh.... My gf phone having this issue.. and i think the problem is the sdcard, class 2 and use it for a2sd..
But, i tried to unroot the problems still happen, even without sdcard, the best way for me is leave this phone.. :-(

simply installed it, and it had it run at lowest speed on idle so it could remain cooler
(you can check the settings on it to see what it runs on idle and modify to your needs anyway)

I have similar problem like yours. I suspect the problem is come from SIM because there is no this kind issue happened IF turn to flight mode or tool out the SIM.

Is mi xperia play unrepairable?

Hi, to start off my xplay fell into the water
I took out the battery and used a drier on it for a long time, when i tried to use it it worked fine however it wouldnt charge battery.
As soon as i was able i changed the battery (to the original factory one, i use a 3400 mah mugen battery) and it wouldnt charge either, then i took it to some technician who jump-started it or something, since then it has been working but the speed of both batteries drain is at last 5 times faster, during my sleep (only data turned on) it discharges about 50%. Drainage is crazy fast.
The phone signal is also very bad, keeps showing that the network is unavailable and sometimes when i try to manually connect to my operator network it does work. the signal display shows 4 bars and still no network even if on the street sometimes. (briefly before i installed doomlord kernel, 2.3.4 android, and jokawild rom in case this issue is known to happen)
This has been going on for like 15 days, everything else works perfectly. However just a couple hours ago touch screen also went mad, it keeps "clicking" all over the place, after doing touch screen service test it keeps drawing lines instead of dots wherever i touch.
I know its a lot of stuff, but i couldnt give up without asking in xda if theres any chance of saving my xplay or i just have to buy a new one.
THX a lot for your feedback.

It sounds like some circuitry may be overcharged from the water, as a similar effect happened with my old laptop. It may not be that though. Personally, I would try to replace it through ebay or the like. I feel bad for you, sorry that happened.

You could keep the microSD and put for sale elsewhere as "for parts"

[Q] R800i Battery & heat issue

Hello,
I've browsed the xda forums and few others extensively for solution of my issue, though to no help at all.
For the starters some numbers and general info:
Phone: R800i Xperia Play, 2.6.32.9-DooMKernel, Xperia NXT v.1.3.
Only default stuff running in the background.
For testing and possible solution, apps I've installed:
Advanced Task Manager,
No-Frills CPU (min. 134 MHz, max 1.114 GHz, smartass, sio),
Battery Defender (Temp 32C, voltage: 3.0V, changed from 4.0V).
I always keep Data, WiFi, Bluetooth, GPS off, unless I need them. Brightness is about 30% most of the time, no auto-brightness control.
For solution purpose I've got manual network selection for 2G, usually it is 2G/3G auto search - never got issues with this.
I've got two batteries, stock one and a Tell Me one, both 1500 MAh, both never had any issues.
Today morning (7AM), as usual, I've disconnected fully charged phone from the charger. I haven't noticed a thing that could be off about the phone.
I've went to the work, and around 11 AM I've messaged a little, and then I've noticed a weird thing - phone was very hot and the battery info said that it is on around 30%. Of course, first I've tried was to reboot the device, and lower the maximum frequency of the CPU.
Unfortunately it wasn't a bug or a mistake - phone really had around 30% charge left. I've got a usb cable from a co-worker to keep the phone from dying.
In the meantime, I've tried resetting the phone to factory defaults, tried flight mode, setting everything to off - nothing helped. Also, what's more weird - phone was charging incredibly slow (that might be because of charging from PC USB) when turned off and it still was hot.
I've realized that phone is getting really hot only in one area - near top right corner (place where light sensor is), on the backside, after you extend the phone (there is a little screw there, under 'sticker').
After getting back to home, I've tried charging the first battery to 100% - it completed, using stock charger, but it took quite longer than expected. Discharging is quite fast - 1% per 4-5 minutes. In ~50 minutes I've got 90%. This gives roughly 7 hours of work on battery. In flight mode, with everything turned off, with CPU on 134 MHz.
On a second battery, which I have in right now, I am steadily progressing from 93% to the 0% at the speed of 1% per 3 minutes.
Phone is +2 years old, not on warranty.
Any advice could be really appreciated.

Is it a stock battery or an aftermarket? I had an aftermarket battery once. It had a similar response in my phone. Bought another battery. OEM and solved it.

Maybe it's battery fault.
One of my battery did the same thing (it even got even bigger due gasses inside it). Replaced it and it's working fine.
If it happends on both batteries, maybe it's hatdware issue. In worste case, something inside phone is shortcutted and drainibg current, causing heating. Maybe opening phone and cleaning parts inside could help.

Wouldn't hurt to open it up and using an eraser clean the battery contacts inside phone and on battery itself. Then use a can of compressed air to blast that bad boy.
Sent from my R800at using xda premium

I've got two different batteries, stock one that came with phone, and a second aftermarket one, which was rarely used - only on long trips when I wanted to play. Both of them couldn't be damaged like that.
Phone never fell on the floor, is always in protective rubber-like 'case' and of course it never even touched water.
Right now heat is strong enough to be a bit painful if you slide the phone out and touch the light sensor area on the backside. I will try to get some torx screwdrivers and open up this part, but I doubt I will find anything. I was wondering if switching back to stock rom could help.
I'm really at loss here since I don't wanna buy new one, though they're cheap right now (about 150$ in my area with 24 month warranty, without any contract), since I've got some holiday plans and wanted to have some more funds. I can go by with the 4-5 hour discharge time if I have a cable on me since I'm working at the office with computers. I can always charge the phone, but knowing that usually I never even fell under 80% after 8 hours at work is kind of bothering.

Have you reformatted the phone via flashing a ftf file... see if that fixes the issue.

Maybe try to use it without battery. Connect charger, remove battery while still powered on, and wait 15minutes (as i recall, it will not turn off). If phone is still hot, then it's not battery related problem.

Actually I've tried this and I've got some results. Phone turns off when it stays this way in OS for a while, so I did that in Boot manager, which I thought won't be affected by OS itself, and I was right - phone stays on, with screen on. Unfortunately, it is very hot in the 'usual' place. So we can root out the possibility that this is a battery issue.I am not quite sure, but also this is certainly not antenna, since it is off in the boot manager, as well as WiFi, BT and GPS.
So could it be that the kernel itself, which must have some module responsible for power management, went crazy? That is just my wild (hopeful) guess, and I wish that flashing will help. Any ROMs that you can advice?

Well, to test if everything is working properly, flash stock firmware with flashtool (even kernel). Test all functions of phone with apps (wifi, BT, gps, 3g, flashlight, tear-front camera). If all works, maybe some chip is overheating.
In that case, if you don't know how to open phone, maybe it's best to take it to service.
If you do know how to open it, first start cleaning enterier. If that don't help, try to power it while dissasembled, and see what chip is overheating and google for it's model to see what it is.

Thanks for advice. I will flash the phone completely to stock and test it. Actually, if it is turned off, it is not heating up but starts to when I try to charge the battery.
I'm working at IT company, but my knowledge ends at the desktop computers actually, certainly I am not into electronics - I can tell when capacitors on motherboard are starting to go bad, but that's it. Starting from laptops, some parts are to small and prone to damage to be just opening and looking around.
I suppose if the stock kernel won't help, I will seek assistance of some service since they always give some kind of warranty for repairs. Of course, I will keep this topic updated, since there might be same kind of lost soul with the same problem.

When you are on stock kernel, test offline charging too (phone turned off, but charging). So heating problem is only limited to battery-charging electronics-kernel).
Post your results when/if it's fixed, no matter what they are. Good luck

Unfortunately, after flashing to stock R800i_4.0.2.A.0.79.ftf I still have this weird overheating issue and the battery is draining really fast. Seems like this is hardware problem, not a software one, since I tested it in many different ways to no help at all.
I will not let go off my XPlay, as I will visit service and try to repair The Best Gaming Phone to Date, though I will buy a new phone, which will be Xperia S, since I've got my eyes on it ever since I played on my friend's one - Final Fantasy 7 with OpenGL plugin in fpse looked really great, and the controls were fine for my tastes.
When I get the XPlay fixed, I will update this thread, since I like this phone and would like to have it back and running.
Thanks for all the help, I really appreciate it

Heating up near home button.

I've been having an issue lately where my S3 will get pretty hot to the touch right above the home button on the screen. The last time this was happening was when I found out that my SD card reader is apparently going bad.
Is it possible that the SD reader is still causing the heat or is there another cause?

that could be but i don't think so as the card slot is higher in the phone. all of the antennas are at the bottom of the phone and if my memory is right so is the cpu. if you are using the phone longer then normal the cpu will heat and make the phone warm front and back also if you have bad cell signal, your phone will turn up the power to the antenna to keep the strongest signal and in turn use more battery. some phone cases can make the phone warmer then normal too. i had a rubber case on an old hd2 phone and after using it for bit it was really warm. if you have just changed or put a case on your phone, maybe take it off and see if it still heats up. just a thought. worse case, i think your phone is going to let you down when you need it most due to being fried from excess heat. if you can't find the reason, take it to sprint and see what those wonderful people say.

The SD card slot is right in the area that I'm talking about.
I'm about to order another battery since my battery life has been kinda crappy lately. I've had the phone for over a year, so it's probably about time to order one.

The exact same thing was happening to my s3 since the first day I got it. It didn't happen to my dads which he got on the same day as me. This excessive heating happened both on touchwiz and aosp with and without the buttons lights turned on. Sprint told me it was normal so at that point it was whatever I got used to it. I'm pretty sure the excessive overheating from doing literally nothing (on debloated aosp roms) eventually destroyed my sd card, I believe.

Gents normally the Device should only feel warm to the touch after extended use. By extended I mean over 45 min, an hour, or more. Even then it should not feel so hot you need to put it down. If your Device is feeling warm near the top of the home button, you may want to Un-Root and take it in to be looked at. If you want to see some pics of the inside of the S3 check out THIS thread.

G3 Freezing, restarting into bootloop

I'm back again XDA. Even more G3 problems!
So since the last time I posted, I've replaced the board on my G3. Everything was great up until the SIM reader quit out. Switched to an HTC One M9 and boy is it terrible. So I use the G3 for music, games, etc. Didn't bother rooting or anything. Running VS9854BA. It's always on Airplane mode with WiFi enabled, I try not to let it overheat since the WiFi went to **** on my last board. And what do ya know, as I was typing up a comment on Facebook the thing just freezes up, makes some ****ed up screeching noise, and tries to restart. I get boot looped and notice a red and blue led. So I pull the battery, hold down the power for a bit and throw the battery back in. It boots up. A few minutes later the phone freezes and does the same thing. The battery level was around 80% on this battery. I try another OEM battery and it works fine for the rest of the night. However, the phone is now doing the same thing with that battery. I've only had issues with non official batteries in the past. For example, one battery I have will make the phone reboot after using the camera. Anyways, I'm iffy on purchasing a new battery. I don't want to pay $6-10 on a POS that was made in 2014. And I don't want to gamble on buying a $15-20 OEM battery from LG, as it may still be old and degraded; or won't even solve the problem. I tried contacting LG to see if I could get any insight, or to see if they are selling newer manufactured BL-53YH batteries and have yet to hear from them. I have noticed most people have issues with LG phones two months after their warranty ends. I was surprised to see the G3 last a few years and would like to get some more time out of it. If my 2011 galaxy nexus still works flawlessly, so should the G3. In the meantime I put a little noctua thermal paste on the EMMC and was baffled by the temperature decrease in cpu z. It still doesn't fix anything though. Any thoughts here? Should I gamble and buy the battery or is this hardware failure?
TLDR: LG devices may be time bombs and their support sucks.

There seems to be a lot of bootloop/battery issues this week. I hope device is not a "time bomb".

"...as I was typing up a comment on Facebook..."
Maybe it's just the universe trying to tell you that Facebook sucks?
Kidding aside - it sounds like your phone is dying a slow death. Normally if you had just the restart issue I would suggest a new battery(even with the reboot at 80% - old batteries get weird), but with the sim issue combined with the screeching noise red/blue light reboot - which usually delivers a green screen kernel panic reboot - it sounds like the weirdness that occurs when a G3 dies.
If it were a bad battery I think it would just shut down, reboot to the LG logo, and then bootloop(that's what mine did when it failed); but failing G3 batteries do some weird things sometimes. To t-shoot a bad battery I guess you could try plugging the phone in and using it while charging to see if any troubles occur; if not, then invest in a battery. I can't say that is a fool proof way to check the battery though...the best way is always to replace it.
If it's (what is believed to be) a solder issue on the board - which a lot of G3 users have reported as the phone has aged - you can try the paper trick to create enough pressure on the chips to complete the solder connection or even using some heat to try and get some solder to reflow, but those are generally only temporary fixes...the issue usually comes back in time. It may be worth it to try the paper trick to help you troubleshoot your issues - if the trick fixes it briefly then you know it's a hardware issue and you can make a decision from there. If you have one of these solder issues it's just best to move on.
So flip a coin: replace the battery for @$20, or say eff-it and get a new phone; sounds like a tough decision...glad I'm not making it - yet.
*If you don't know what the paper trick is just search the G3 forums...screen flicker threads usually mention it and there are other threads out there too.
