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.

Extremely high phone temp!

Does anyone have issues with your SGSII T989 phones having extremely high temps?
I get it when using the GPS, charging the phone while i'm talking on the phone, and doing a few other activities. It did not do this on my first purchase of the phone and i'm a bit weary of the temps as sometiems it gets quite warm!
Currently I'm on O.E. SGS II Rom w/ root, that's about it! No OC no mods or anything of that sort. (Just CWM and Root).
Any tips would be greatly appreciated, as this heat as caused me from using my phone each day more and more.
P.S. I WAS on Juggernaut Rom and then flashed back to Stock, and it was having this heating issue then, should i try to do a complete 100% wipe like on one of the development threads and start from scratch like I just got the phone from the factory again? I wiped my system using Odin and it seems to of kept my old programs, no information like games and etc. was kept however, does anyone think that might be the problem? Once again thanks!

If you are rooted you might want to try a different kernel and maybe SetCPU. I had some overheating/temp issues a while back and after I lowered my CPU a bit and set it to an Ondemand state with a profile for screen off running CPU very low when not actively in use it seemed to fix the problem.. Btw SetCPU is free for XDA users, there is a thread somewhere in the Android Hacking Apps forum..

Edit: I thought it was free to xda users, I checked and cant find the thread, maybe I was wrong or they changed it..

I'm on the stock kernal, I was on the modified 1.7ghz kernal before i believe, as I could overclock over that, but i just recently stopped that and went back to stock. I was and still am expecting the phone to malfunction on me sometime soon lol. It's been a really reliable phone so far! My G1 and Mytouch 3G slide (gf's phone) took soo many dumps on me while I used it. Each of those phones were probably sent back 5-8 times and they were kept completely stock for a while!
Back on subject though. Any kernals that go well with the factory rom? I don't favor any aftermarket roms right now as they're not stable enough for my usage IMO.

I have heat problems but I've always had the stock kernel...

Undervolt at the stock clock if you want to lower temps. However, charging will always increase heat especially if you are using the phone at the same time, and depending on ambient temps.

Dude my moms sgsII literally got fried because it heated up once. She was using her phone normally and all of a sudden it started heating up. She kept using it and the next day the phone won't turn on, charge or get into download mode. It looked like what a hard brick would look like. So I just returned it for a HTC one S.
Btw she was on full stock.
My phone heats up a lot because I'm down south with 90-95 degree temps and I keep phone in the car dock by the windshield but it never failed on me.
Sent from my SGH-T989 using XDA

I thought it was a well fixable issue. Guess not? lol... Either way, everytime my batt temps rise, i notice i get 40-45C and i start to get worried. So if i'm in a car, i'd just put it next to the AC vent while the car's running and temps get down to about 25C and i'm good again. I just don't feel comfortable with the phone anymore like I use to. It never did this before, why now??

I have an app that warns when it goes over 40 and it happens daily. I was downloading torrents one time and it keeps the screen active while downloading and the thing got like 62 celsius before I realized what happened. It almost burnt my hand lol. if your ever in sunlight or palming the phone while using gps on 4g.
overheating is very common with this phone I wouldn't worrie about it to much it is uncomfortable though if in your pocket

Also remember, any app that uses hardware acceleration for graphics or video (games, browser, etc.) or gps will cause the phone to heat up if used for a prolonged period of time.
Playing Osmos was like setting my phone on fire.

Are you sure I shouldn't worry? I mean, I don't want solder points falling off due to too high of a temp. Then again these temps don't even reach 100C yet. I've got the same app too probably, it's a battery monitor that tells u when the phone gets too hot. mine's goes off everytime i'm around 40+

Yep, I use GPS and often. It's just so much easier than guessing your way off a piece of paper. But yeah, like you the phone gets soo hottttttt. I have to always put the phone to my AC vent.

It's normal to a point.
These are serious computers we have.
Think of the old P486's back in the day, those things needed huge heat sinks and some even had fans
our phones which is what, 4x the cpu power and not only no heat sink but everything is squished together inbetween a hot screen and a hot battery
That being said, I use a program called A-see, which is to watch my security cameras while out.
And if I forget to close it out (Actually exit the program) It will keep running and running and eventually probably fry my phone
lets put it this way, I will actually start to feel it in my jeans pocket, it gets that hot.
Also I have a program which will alert me if my phone gets to 130 degrees F
And will automatically shut the phone down if it gets to 140
overheat protection or something

I had this issue where whenever I try to charge my phone it would overheat to the point unbearable to touch I went back to stock flash different roms in the end i exchanged it it was still under warranty

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.

[Q] Note2 Overheats while Powered Down?

Greetings,
My brother's Note2 has started being seriously unreliable. Just seeing it today at Thanksgiving Dinner, I witnessed the phone sitting powered off and warm, to the touch. I would estimate it to be around 110 - 120*F POWERED OFF!
When I did turn it on, the I looked at the battery useage, and noted the NFC function was using 30%. I then went into the settings to disable it, but it was already disabled. Then the phone crashed and rebooted. I pulled and inspected the battery. The water marker was dry, the battery was not warped or bulging, and it was not hotter then the processor area of the phone.
Has anyone seen this?
He has a new battery on its way so perhaps that is the problem, however I suspect faulty hardware or perhaps software.
He went to the store and was told he would need to pay $200 for a warranty claim, outrageous!
Thanks in advance!
Matt|ttaM

It would most probably be the battery problem. If u using a custom rom or kernel, reflash/flash a different one.

Just do a factory wipe..
and format all your memory partitions..
i had this crashing issue once.. most probably a rouge app messing up..

Do as @geekynoob said above and after flashing new ROM (possibly Custom ROM) do following :
1. Charge it to 100%
2. Install BetterBatteryStats
3. Install CPU Spy Plus
4. Reboot phone
5. Launch both apps and exit them (they'll keep running in the background collecting data)
6. Take reading through (just look at app screen) both after using your device normally for minimum 6-7hrs.
Share those readings here (through Screenshot probably). We will try to troubleshoot issues, if any remaining, after fresh install.
Btw, I don't think it has got anything to do with battery.

Thanks for the replies, guys.
He is still on the stock ROM. I will try what you mentioned and report the findings.

Just a quick update. He has read this post, and taken your advisements. He says the phone doesn't overheat now, but he is having issues connecting to WiFi.
Any suggestions?

He told me he removed more apps, and now the wifi works and the battery lasts all day again. So it would seem problem solved.
I am just curious how an app could be pegging the battery useage for NFC even though it is off in the settings.

tab gets flickering screen and reboots

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

If you have the ability, since it was dropped, I would open it and make sure connection is tight to battery and screen. Then if it still acts up, get a battery. Several people had battery issues out of the box. All it turned out to be for a few was a loose connection.

i was thinking about that but i'm afraid of voiding warranty. do i even still have warranty? due to the knox?

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

I'm not by any means an expert or repairman of any kind, just so you know. I'm thinking maybe a loose connection at the terminals on the board the battery connects to or if they use a separate board for the battery to connect to and then to the main board it may be somewhere along in there. Maybe a loose wire going into the tab that connects to the prongs. It sure sounds like something isn't making a good connection. Sounds like a load gets put on it and it and that bad connection can't handle the load.
Might just be you're going to have to send it off...

You may be right. Sounds like a particular connection which does higher load or something. Once i put the tablet in power save mode, the symptoms never reappeared. I dont notice a drastic slowdown in the tablet either. Probably am prolonging the inevitable.

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

nope, ever since the Power Saving mode solution, it hasnt flickered and rebooted yet. and my warranty was expired by that point so i didnt bring it to the shop. no noticable reduction in performance so far

I have seen this problems on 2 tablets 10.5 and 8.4 the connector where battery is connected on motherboard gets loose which causes reboots and flicker
Solution in my case was resoldering that connector again

i had the same problem, opened up my tablet, just disconnected the battery, cleaned the contacts, pushed it back, made sure its nice and snug, put it all back together and now battery doesn't drain as fast, no more flickers and reboots!

hmm. i'll have to give it a try. you think this may be something to do with condensation?

Sorry for the bump, but I'm having this issue as well on my S 8.4. Custom ROM. The thing with me is that it's not consistent. One day, it will do it a few times; others, no issues whatsoever. I'll try the suggested if it gets progressively worse.

Hey guys,
Unfortunately our home's tablet (Tab s 8.4 Wifi) has the same problem.
It never did weird whatshowever, but when I flashed a custom rom (which went perfectly smooth actually) the screen flashes and the tablet reboots sometimes.
Now it weird that this never happened before and only when I flashed a custom rom it began showing this behaviour.
I am affraid of opening this tablet, and I guess because of the custom rom there is no warranty left anymore (or can this be bypassed by some terminal trick?)
Also I question myself if this is not a software issue, and that it can be fixed with software or so?
Thanks for answering!

My Fix
Hey Guys!
I might have some surprising news to tell about this "issue".
I saw some unboxing video's and saw at what place the battery connector was placed. It was some sort of a 'push to click' system.
So what I did was the following:
I pushed the tablet at the place of the battery connector. I tried this at various places until I heard a *click*.
Now I don't have this issue anymore. Jay!
I hope this will help you too!

I started to have the same issue on a Tab Pro 12.2, presumably after the battery has lost considerable amount of its energy. Normally I remember this tablet to have a dazzling 10+ hours of usage time. Just after some serious usage time of more than 2 years this issue started, along with increasing temperature and finally reboot. From time to time Android gave a warning message about overheating. From time to time charge values drop big values at a time. From 45 to 20 or 80 to 50. Seems arbitrary. This was happening even when I was on stock, then I switched to some Android 6 stock port from some other tablet. Still the same.
I believe the battery needs replacement. (That's obvious after 18 months, I just mean blinking is related to this) Hope I can find a high quality one cause there are several garbage batteries.
